Description
본 발명은 중앙식 연속 아스콘 생산장치 및 그 방법에 관한 것으로, 보다 상세하게는 한번에 많은 양의 재생골재와 신골재를 이용하거나, 재생골재 또는 신골재만을 이용하여 고정된 장소에서 연속적으로 아스콘을 생산할 수 있도록 함과 동시에 고품질의 아스콘을 얻을 수 있도록 한 중앙식 연속 아스콘 생산장치 및 그 방법에 관한 것이다. The present invention relates to a central continuous ascon production apparatus and method thereof, and more particularly, to produce ascon continuously in a fixed place using a large amount of recycled aggregates and new aggregates at once, or using only recycled aggregates or new aggregates. The present invention relates to a central continuous ascon production apparatus and method for achieving high quality ascon while at the same time.
최근 급격한 경제성장과 기간산업의 발달로 도로를 신설, 보수하거나 재건설함으로 인해 아스콘 생산량이 급격히 증가하고 있다.Ascon production has increased rapidly due to the recent economic growth and the development of infrastructure, as new roads have been built, repaired or rebuilt.
이러한 아스콘 사용량의 증가로 인해 보다 많은 아스콘을 생산하기 위한 장치들이 개발되고 있다.Due to the increase in the use of ascone, devices for producing more ascones are being developed.
이 중에서 도 1에 도시된 바와 같은 배치식 아스콘 생장장치(10)는 아스콘을 입도별로 수용하는 다수개의 콜드빈(12)이 구비되고, 콜드빈(12)으로부터 배출되는 골재를 이송시키는 이송컨베이어(14)가 구비되며, 이송컨베이어(14)로 이송된 골재를 가열하는 가열로(16)가 구비되며, 가열된 핫골재를 이송시키는 핫엘리베이터(18)가 구비되고, 이송된 골재를 입도별로 분리하는 진동스크린(22)이 구비되며, 진동스크린(22)에서 선별되는 골재가 입도별로 저장되는 다수개의 핫빈(24)이 구비되고, 핫빈(24)에 저장된 핫골재를 용량 비율로 배출하여 혼합하는 혼합부(26)로 구성되어 있다.Among them, the batch-type ascon growth apparatus 10 as shown in FIG. 1 is provided with a plurality of cold bins 12 accommodating ascon by size, and a conveying conveyor for transporting aggregates discharged from the cold bins 12 ( 14) is provided, the heating furnace 16 for heating the aggregate transported to the conveying conveyor 14, is provided with a hot elevator 18 for transporting the heated hot aggregate, and separates the transported aggregate by particle size Is provided with a vibration screen 22, a plurality of hot bins 24 are stored for each aggregate size of the aggregates selected from the vibration screen 22, and discharged by mixing the hot aggregate stored in the hot bin 24 in the capacity ratio It consists of the mixing part 26.
이와 같이 구성된 종래의 배치식 아스콘 생산장치는 분쇄된 골재를 입도별로 선별하여 콜드빈에 수용시키고, 콜드빈에 수용된 골재는 이송컨베이어의 상부로 배출되어 이송되고, 이송된 골재는 가열로로 공급되며, 이 골재는 가열로의 내면에 부착된 옆지날개에 의해 분산, 가열, 전진되어 가열로의 끝에서 배출되고 배출된 핫골재는 이송엘리베이터로 배치탑의 상부에 공급되며, 여기서 핫골재는 진동스크린에 의해 입도별로 분리되어 핫빈에 저장된다.The conventional batch-type ascon production apparatus configured as described above sorts the crushed aggregates by particle size and accommodates them in the cold bin. The aggregates contained in the cold bin are discharged to the upper portion of the conveying conveyor, and the transferred aggregate is supplied to the heating furnace. The aggregate is distributed, heated and advanced by side blades attached to the inner surface of the furnace, and is discharged from the end of the furnace. The discharged hot aggregate is supplied to the upper part of the batch tower by a transfer elevator, where the hot aggregate is a vibrating screen. It is separated by particle size and stored in hot bean.
이렇게 핫빈에 입도별로 저장된 핫골재는 혼합비율에 맞게 입도별로 배출되어 혼합부로 공급되어 혼합이 이루어져 아스콘의 생산이 완료되게 된다.The hot aggregate stored by the particle size in the hot bean is discharged by the particle size according to the mixing ratio and supplied to the mixing part to be mixed to complete the production of ascon.
그러나, 종래의 아스콘 생산장치는 구조와 과정이 복잡하여 골재를 이용하여 아스콘을 생산하는데 많은 시간과 장소가 소요되는 문제점이 있었다.However, the conventional ascon production apparatus has a problem that it takes a lot of time and place to produce ascon using the aggregate because the structure and process is complicated.
또한, 입도가 서로 다른 골재를 혼합하여 가열한 후 가열된 핫골재를 입도별로 다시 분리하는 추가적인 작업과, 분리된 핫골재를 입도별로 저장하는 다수개의 핫빈을 구비하여야 하고, 드럼건조기 내부를 통과하는 가열공기와 함께 배출되는 미세분진도 심각하여 이들을 포집할 집진설비가 필요하였다.In addition, after mixing and heating aggregates having different particle sizes, additional work for separating the heated hot aggregates by particle size and a plurality of hot bins for storing the separated hot aggregates by particle size should be provided. The fine dust discharged with the heated air was also serious, and a dust collecting facility was needed to collect them.
따라서, 중앙식 배치 아스콘 생산공정은 골재 드럼건조기 이 외에도, 가열골재 이송장비, 이를 저장하는 핫빈, 핫빈의 가열골재가 투입되는 퍼그밀 혼합기, 페아스콘 가열용 드럼건조기, 페아스콘 저장 핫빈, 집진설비, 등과 같은 추가적인 장비들과 이들의 설치공간이 필요하며 이에 따라 공정이 복잡해지고 공간을 많이 차지하는 문제점이 있었다.Therefore, the central batch ascon production process is not only aggregate drum dryer, but also heating aggregate transfer equipment, a hot bin for storing it, a pug mill mixer in which the hot aggregate is fed, a drum dryer for heating peascon, a peascon storage hot bin, and a dust collecting facility. Additional equipment such as, and installation space thereof are required, and thus there is a problem that the process becomes complicated and takes up a lot of space.
그리고, 핫빈의 저장용량이 한정되어 있어 한번에 산할 수 있는 아스콘의 생산량이 제한받게 되어 대형 도로보수공사시에는 부적합한 문제점이 있었다.In addition, the storage capacity of the hot bean is limited because the production of ascone that can be produced at a time is limited, there was an unsuitable problem during large road repair work.
즉, 대형 도로 공사 시에는 아스콘의 생산작업을 수회에 걸쳐 반복적으로 진행해야 하기 때문에 아스콘의 생산시간이 오래 걸릴 뿐만 아니라, 공사의 연속성이 떨어지는 문제점이 있었다.In other words, during the construction of large roads, the production of ascon must be repeatedly performed several times, and therefore, the production time of the ascon is not only long, but there is a problem in that the continuity of construction is inferior.
그리고, 중앙식 연속 아스콘 생산 장치의 경우에는 드럼혼합기 자체가 일정한 경사 각도를 가지도록 구비되며, 혼합기의 원통 내면에 원주를 따라 일정한 길이의 엽지날개 다수개가 붙어서 한세트를 이루며, 원통의 길이 방향으로 여러 세트의 엽지날개가 붙어 있다.In the case of the central continuous ascon production apparatus, the drum mixer itself is provided to have a constant inclination angle, and a plurality of leaf blades of a constant length are attached to the inner surface of the mixer along the circumference to form a set, and in the longitudinal direction of the cylinder There is a leaf blade of the set.
따라서, 상기 드럼이 회전함에 따라 엽지날개의 홈이 원통의 밑면에 있는 재료를 퍼 올려서 상부에 도달하면 엽지날개의 위치가 거뚜로 되어 홈의 재료가 혼합원통이 기울어진 방향으로 떨어지게 되는데, 이때 원통 내부를 지나가는 버너의 열풍과 교차하며 떨어져 재료의 분사, 가열 및 이송을 하게 된다.Therefore, as the drum rotates, the grooves of the blade blade reach the upper part by spreading the material at the bottom of the cylinder, and the position of the blade blade becomes rough, so that the material of the groove falls in the direction in which the mixing cylinder is inclined. It intersects with the hot air of the burner passing inside, and is sprayed, heated and transferred.
그러나, 이러한 방법의 가열과 이송은 재료의 단순혼합을 가져올 뿐이며 재료간의 전단마찰 효과가 거의 없어서 혼합과 가열에 오랜 시간이 걸릴 뿐 아니라, 폐아스콘을 재생할 경우에는 단순혼합에 따른 혼합불량으로 불균일한 재료가 생산되는 문제가 있어 왔다.However, this method of heating and conveying only results in the simple mixing of materials, and there is almost no shear friction effect between the materials, which takes a long time for mixing and heating, and in the case of regenerating waste ascon, uneven mixing due to the simple mixing There has been a problem that the material is produced.
그리고, 종래의 중앙식 연속 아스콘 생산설비는 배치식과는 달리 공간을 적게 차지하고 본 발명과 유사한 장비와 공간을 필요로 하는 장점이 있다. In addition, the conventional central continuous ascon production facility has a merit that requires less space and similar equipment and space as the present invention, unlike the batch type.
그러나, 회전통의 한쪽 끝에 설치된 버너의 직접가열에 의해 노출된 골재의 과다가열이 골재와 접촉하는 아스팔트를 급격히 산화노화 시킬 수 있는 문제가 있고, 무엇보다도 회전통 내부에 붙어 있는 엽지날개에 의한 혼합이 비효율적이어서 완전혼합에 이르기까지 충분한 혼합공간과 시간이 필요하다. However, there is a problem that the overheating of aggregate exposed by direct heating of the burner installed at one end of the rotating cylinder can rapidly oxidize the asphalt in contact with the aggregate, and above all, mixing by leaf blades attached inside the rotating cylinder. This is inefficient and requires sufficient mixing space and time to reach full mixing.
즉, 드럼혼합기의 길이를 충분히 길게 하여 혼합시간을 늘리지 않으면 혼합품질도 나쁘고 생산량도 적어지는 구조적 단점이 있다. In other words, if the length of the drum mixer is not long enough to increase the mixing time, there is a structural disadvantage that the mixing quality is poor and the production amount is small.
본 발명은 상기한 종래의 문제점을 해결하기 위하여 안출된 것으로, 본 발명에서는 이중원통을 사용하여 외통의 내주와 내통의 위주 사이에서 골재의 이송과 혼합이 골재의 투입과 동시에 진행되어 생산공정의 단순화, 생산효율의 증가, 생산량의 극대화를 꾀할 수 있도록 하는데 그 목적이 있다.The present invention has been made to solve the above-mentioned conventional problems, in the present invention, the transfer and mixing of aggregate between the inner circumference of the outer cylinder and the circumference of the inner cylinder using a double cylinder proceeds at the same time as the input of aggregate to simplify the production process The aim is to increase production efficiency and maximize production.
그리고, 골재의 이송과 혼합에 압출 스크루식의 플라이트 역할을 하면서 일정한 길이와 간격을 가진 교반부재를 사용하여 나선형방향으로 전단마찰을 일으켜 혼합을 행함으로서, 효과적인 혼합을 달성할 수 있도록 하는데 그 목적이 있다.The purpose of the present invention is to achieve effective mixing by performing shear friction in a helical direction by using a stirring member having a constant length and spacing while acting as an extrusion screw type flight for mixing and conveying aggregates. have.
또한, 종래의 방법에서는 가열이 하나의 원통내에서 재료이송과 함께 행해진 후 혼합부로 이송됨으로 이송과정에서 열손실이 발생하고 골재이송에서의 열풍에 의해 발생하는 분진을 제거하기 위해 집진기를 설치하는 반면에, 본 발명에서는 재료의 이송과 혼합이 내통의 위주에서 행해지고 내통의 내부에서는 가열이 행해짐으로 재료와 열의 이동이 완전히 분리되는 간접 가열방식을 채택하여 재료의 산화노화를 엄격히 제어함과 동시에, 재료이송과 혼합이 가열과 함께 행해져 열손실이 거의 없을 뿐더러, 재료가 혼합기에 투입됨과 동시에 아스팔트를 포함하는 유기첨가제가 분사되어 골재를 피복시켜 윤활작용을 하게 할 뿐만 아니라 분진을 최소화함으로서 집진설비가 필요 없도록 하는데 그 목적이 있다.In addition, in the conventional method, since the heating is carried out together with the material transfer in one cylinder and then transferred to the mixing unit, a dust collector is installed in order to remove dust generated by the hot air in the aggregate transport, while the dust collector is installed. In the present invention, the transfer and mixing of the material is performed mainly in the inner cylinder, and the heating is performed in the inner cylinder to adopt an indirect heating method that completely separates the movement of the material and heat, thereby strictly controlling the aging of the material and simultaneously Transfer and mixing are performed together with heating, so there is almost no heat loss. In addition, materials are added to the mixer and organic additives including asphalt are sprayed to coat the aggregate to lubricate and minimize dust. The purpose is to make sure that
나아가, 폐골재와 신골재를 입도별로 분리하여 다수개의 콜드빈에 저장한 후 저장된 골재를 혼합비율로 배출시키고 가열부에서 전단마찰에 의한 교반과 간접가열을 가하여 균질한 아스콘을 생산함으로써, 품질이 우수한 아스콘 생산과 생산공정의 단순화와 단시간에 다량의 아스콘 생산이 가능하도록 하는데 그 목적이 있다.Furthermore, waste aggregates and new aggregates are separated by particle size and stored in a plurality of cold bins, and then the stored aggregates are discharged at a mixing ratio, and a homogeneous ascon is produced by stirring and indirect heating by shear friction at the heating unit. Its purpose is to make excellent ascon production, simplify the production process, and to produce large quantities of ascon in a short time.
또한, 본 발명에 의한 드럼혼합기의 특징은 재료와 열의 흐름이 이중원통에 의해 분리된 간접가열방식을 채택함으로서 아스팔트가 직접 가열원에 노출되지 않아 산화노화가 경감되고, 열풍에 의한 분진의 방출문제가 해소되고, 아스팔트와 유기재료를 골재의 초입에 첨가하여 처음부터 골재를 피복시킴으로서 건조골재의 마찰에 의한 과부하와 분진발생을 최소화시키고, 교반부재의 나선형 회전에 의해 재료 간의 전단마찰과 혼합을 원활하게 성취함으로서 효과적인 혼합을 할 수 있도록 하는데 그 목적이 있다.In addition, the drum mixer according to the present invention is characterized by adopting an indirect heating method in which the flow of material and heat are separated by a double cylinder, so that asphalt is not directly exposed to a heating source, thereby reducing oxidative aging and emitting dust by hot air. By adding asphalt and organic materials to the beginning of the aggregate and covering the aggregate from the beginning, it minimizes the overload and dust generation caused by friction of the dry aggregate and smoothes the shear friction and mixing between the materials by the spiral rotation of the stirring member. Its purpose is to enable effective mixing by accomplishing this.
그리고, 내통의 일측, 즉 골재가 공급되는 방향은 직경이 작고, 배출되는 방향은 직경을 크게 형성함으로써, 폐골재나 신골재의 투입을 용이하게 이루어지도록 하는데 그 목적이 있다.In addition, one side of the inner cylinder, that is, the direction in which the aggregate is supplied is small in diameter, and the discharge direction is formed to have a large diameter, so that it is easy to input the waste aggregate or new aggregate.
또한, 아스팔트나 유기재료를 첨가할 수 있는 공간이 생겨서 초입부터 골재를 피복시켜 윤활작용을 하게 함으로서, 과부하가 발생하는 것을 방지함과 동시에 재료의 과잉공급 시에 제1,2호퍼가 막히는 것을 방지 할 수 있도록 하는데 그 목적이 있다.In addition, there is a space for adding asphalt or organic materials to coat the aggregate from the beginning to lubricate, preventing overloading and blocking of the first and second hoppers during oversupply. The purpose is to make it possible.
또한, 내통의 일측부에 버너가 구비되고, 내통의 내측에는 다수개의 칸막이가 구비되고, 이 칸막이에는 다수개의 통공이 형성되어 버너에 의해 발생한 열기가 급속하게 타측으로 배출되지 않고 내통의 내측에 정체된 상태로 서서히 타측부로 배출되도록 함으로써, 열효율을 극대화시킬 수 있도록 하는데 그 목적이 있다.In addition, a burner is provided at one side of the inner cylinder, and a plurality of partitions are provided inside the inner cylinder, and a plurality of through holes are formed in the partition so that the heat generated by the burner is not rapidly discharged to the other side and is stagnated inside the inner cylinder. In order to be discharged to the other side in a steady state, the purpose is to maximize the thermal efficiency.
그리고, 내통으로부터 배출되는 폐열을 회수하여 폐골재가 투입되는 제1호퍼를 가열할 수 있도록 회수관이 배관되어 폐열을 재사용함으로써, 열손실을 방지함과 동시에 골재를 예열하여 효과적인 혼합을 준비시킴으로서, 우수한 재생 혹은 신규아스콘을 생산할 수 있도록 하는데 그 목적이 있다.And, by recovering the waste heat discharged from the inner cylinder to heat the first hopper into which the waste aggregate is injected, the recovery pipe is piped to reuse the waste heat, thereby preventing heat loss and preheating the aggregate to prepare effective mixing, Its purpose is to be able to produce excellent recycled or new ascon.
한편, 상기 폐아스콘 재생하는 과정에서 방생하는 수증기를 별도로 회수하여 이 수중기를 냉각시킴과 동시에 수중기를 냉각시킬 때 발생하는 응축수는 별도로 포집하고 응축수가 제거된 공기를 외부로 배출시킴으로써, 환경이 오염되는 것을 방지할 수 있도록 하는데 그 목적이 있다.Meanwhile, by separately recovering the water vapor generated during the recycling of the waste ascon, the condensed water generated when the water cooler is cooled and the water condensed water is collected separately and discharged the air from which the condensed water is removed. The purpose is to help prevent this.

이와 같이 구성된 본 발명은 이중원통을 사용하여 외통의 내주와 내통의 위주 사이에서 골재의 이송과 혼합이 골재의 투입과 동시에 진행되어 생산공정의 단순화, 생산효율의 증가, 생산량의 극대화를 꾀할 수 있도록 하는 효과가 있다.In the present invention configured as described above, the transfer and mixing of aggregate between the inner circumference of the outer cylinder and the inner circumference of the inner cylinder is carried out at the same time as the input of the aggregate to simplify the production process, increase the production efficiency, and maximize the yield. It is effective.
그리고, 골재의 이송과 혼합에 압출 스크루식의 교반부재를 사용하여 나선형방향으로 전단마찰에 의한 이송과 혼합을 행함으로서, 종래의 방법보다 훨씬 효과적인 혼합을 달성할 수 있도록 하는 효과가 있다.Further, by using the extrusion screw type stirring member for conveying and mixing the aggregate, the conveying and mixing by shear friction in the helical direction has an effect of achieving a much more effective mixing than the conventional method.
또한, 종래의 방법에서는 가열이 하나의 원통내에서 재료이송과 함께 행해진 후 혼합부로 이송됨으로 이송과정에서 열손실이 발생하고 골재이송부에서 발생하는 분진을 제거하기 위해 집진기를 설치하는 반면에, 본 발명에서는 재료의 이송과 혼합이 내통의 위주에서 행해지고 내통의 내부에서는 가열이 행해짐으로 재료와 열의 이동이 완전히 분리되는 간접 가열방식을 채택하여 재료의 산화노화를 엄격히 제어함과 동시에, 재료이송과 혼합이 가열과 함께 행해져 열손실이 거의 없을 뿐더러, 재료가 혼합기에 투입됨과 동시에 아스팔트를 포함하는 유기첨가제가 분사되어 골재를 피복시켜 윤활작용을 하게 할 뿐만 아니라 분진의 발생을 소멸시킴으로써, 집진설비가 필요 없도록 하는 효과가 있다.In addition, in the conventional method, since heating is performed together with material transfer in one cylinder and then transferred to the mixing section, heat loss occurs during the transfer process and a dust collector is installed to remove dust generated in the aggregate transfer section. In the inner cylinder, heating and mixing of materials are carried out mainly, and heating is carried out inside the cylinder to adopt an indirect heating method that completely separates the movement of materials and heat. It is done with heating, so there is almost no heat loss, the material is introduced into the mixer, and the organic additives including asphalt are sprayed to coat the aggregate to lubricate and eliminate the generation of dust, thus eliminating dust collection equipment. It is effective.
나아가, 폐골재와 신골재를 입도별로 분리하여 다수개의 콜드빈에 저장한 후 저장된 골재를 혼합비율로 배출시키고 가열부에서 전단마찰에 의한 교반과 간접가열을 가하여 균질한 아스콘을 생산함으로써, 품질이 우수한 아스콘 생산과 생산공정의 단순화와 단시간에 다량의 아스콘 생산이 가능하도록 하는 효과가 있다.Furthermore, waste aggregates and new aggregates are separated by particle size and stored in a plurality of cold bins, and then the stored aggregates are discharged at a mixing ratio, and a homogeneous ascon is produced by stirring and indirect heating by shear friction at the heating unit. It has the effect of producing excellent ascon and simplifying the production process and producing large quantities of ascon in a short time.
또한, 본 발명에 의한 드럼혼합기의 특징은 재료와 열의 흐름이 이중원통에 의해 분리된 간접가열방식을 채택함으로서 아스팔트가 직접 가열원에 노출되지 않아 산화노화가 경감되고, 열풍에 의한 분진의 방출문제가 해소되고, 아스팔트와 유기재료를 골재의 초입에 첨가하여 처음부터 골재를 피복시킴으로서 건조골재의 마찰에 의한 과부하와 분진발생을 최소화시키고, 교반부재의 나선형 회전에 의해 재료 간의 전단마찰과 혼합을 원활하게 성취함으로서, 용이하게 혼합을 할 수 있도록 하는 효과가 있다.In addition, the drum mixer according to the present invention is characterized by adopting an indirect heating method in which the flow of material and heat are separated by a double cylinder, so that asphalt is not directly exposed to a heating source, thereby reducing oxidative aging and emitting dust by hot air. By adding asphalt and organic materials to the beginning of the aggregate and covering the aggregate from the beginning, it minimizes the overload and dust generation caused by friction of the dry aggregate and smoothes the shear friction and mixing between the materials by the spiral rotation of the stirring member. By achieving this, it is possible to easily mix.
그리고, 내통의 일측, 즉 골재가 공급되는 방향은 직경이 작고, 배출되는 방향은 직경을 크게 형성함으로써, 폐골재나 신골재의 투입을 용이하게 이루어지도록 하는 효과가 있다.In addition, one side of the inner cylinder, that is, the direction in which the aggregate is supplied has a small diameter, and the discharge direction has a large diameter, thereby making it easy to add waste aggregate or new aggregate.
또한, 아스팔트나 유기재료를 첨가할 수 있는 공간이 생겨서 초입부터 골재를 피복시켜 윤활작용을 하게 함으로서, 과부하가 발생하는 것을 방지함과 동시에 재료의 과잉공급 시에 제1,2호퍼가 막히는 것을 방지 할 수 있도록 하는 효과가 있다.In addition, there is a space for adding asphalt or organic materials to coat the aggregate from the beginning to lubricate, preventing overloading and blocking of the first and second hoppers during oversupply. It has the effect of making it possible.
또한, 내통의 일측부에 버너가 구비되고, 내통의 내측에는 다수개의 칸막이가 구비되고, 이 칸막이에는 다수개의 통공이 형성되어 버너에 의해 발생한 열기가 급속하게 타측으로 배출되지 않고 내통의 내측에 정체된 상태로 서서히 타측부로 배출되도록 함으로써, 열효율을 극대화시킬 수 있도록 하는 효과가 있다.In addition, a burner is provided at one side of the inner cylinder, and a plurality of partitions are provided inside the inner cylinder, and a plurality of through holes are formed in the partition so that the heat generated by the burner is not rapidly discharged to the other side and is stagnated inside the inner cylinder. By gradually discharging to the other side in the state, there is an effect to maximize the thermal efficiency.
그리고, 내통으로부터 배출되는 폐열을 회수하여 폐골재가 투입되는 제1호퍼를 가열할 수 있도록 회수관이 배관되어 폐열을 재사용함으로써, 열손실을 방지함과 동시에 골재를 예열하여 효과적인 혼합을 준비시킴으로서, 우수한 재생 혹은 신규아스콘을 생산할 수 있도록 하는 효과가 있다.And, by recovering the waste heat discharged from the inner cylinder to heat the first hopper into which the waste aggregate is injected, the recovery pipe is piped to reuse the waste heat, thereby preventing heat loss and preheating the aggregate to prepare effective mixing, It is effective to produce excellent recycled or new ascon.
한편, 상기 폐아스콘 재생하는 과정에서 방생하는 수증기를 별도로 회수하여 이 수중기를 냉각시킴과 동시에 수중기를 냉각시킬 때 발생하는 응축수는 별도로 포집하고 응축수가 제거된 공기를 외부로 배출시킴으로써, 환경이 오염되는 것을 방지할 수 있도록 하는 효과가 있다.Meanwhile, by separately recovering the water vapor generated during the recycling of the waste ascon, the condensed water generated when the water cooler is cooled and the water condensed water is collected separately and discharged the air from which the condensed water is removed. There is an effect that can be prevented.

At this time, if the slip is severe, the stirring member is in vain and the aggregate transfer is not possible to prevent the embossing, grooving, grooved or recessed groove 430 to prevent the contact surface of the stirring member 430 It must be made or processed in various patterns.
이렇게, 상기 교반부재(430)는 골재와의 마찰로 인해 마모되기 쉬움으로 이를 방지하도록 내마모강으로 제조되어야 한다. Thus, the stirring member 430 is to be made of wear-resistant steel to prevent this due to the wear and tear due to friction with the aggregate.
본 발명에서처럼 교반부재가 전단마찰에 의해 재료를 나선방향으로 이송하는 방법은, 기존장비에서처럼 회전원통 내벽에 경사져 달린 엽지날개가 재료를 이송하는 방법과는 혼합효율 면에서 큰 차이가 있다. As in the present invention, the method of conveying the material in the spiral direction by the shear friction in the stirring member, as in the existing equipment, has a big difference in terms of mixing efficiency from the method in which the blade blades inclined to the inner wall of the rotating cylinder convey the material.
기존방법에서는 혼합기 원통이 회전하게 되면 내벽에 붙은 엽지날개의 홈에 원통밑면의 재료를 퍼 올려서 상부에서 엽지날개가 거꾸로 되어 홈의 재료가 중력에 의해 날개가 부착된 각도로 뿌려짐으로서 재료의 이송과 혼합을 이루게 되지만, 본 발명에서의 교반부재는 압출스크루 식의 전단마찰에 의해 재료 간의 강력한 혼합을 유도하면서 나선방향으로 재료를 이송시킨다. In the conventional method, when the mixer cylinder is rotated, the material of the bottom of the cylinder is spread in the groove of the blade blade attached to the inner wall so that the blade blade is inverted from the top, so that the material of the groove is scattered at the angle of the wing attached by gravity to transfer the material. Although the mixing with the present invention, the stirring member in the present invention transfers the material in the spiral direction while inducing strong mixing between the materials by the shear screw of the extrusion screw type.
즉, 재료의 혼합기능을 고려할 때 본 발명의 교반부재(430)는 재료간의 강력한 전단마찰을 유도하여 혼합시키는 반면에, 종래의 엽지날개는 단순히 재료를 섞어주는 역할만을 하는 차이가 있기 때문에 두 방법 간에는 비교할 수 없을 만큼 큰 혼합효율성의 차이가 존재하며, 본 발명에 의한 혼합방법이 훨씬 우수하다.That is, when considering the mixing function of the material, the stirring member 430 of the present invention induces strong shear friction between the materials, while mixing, whereas the conventional leaf blades have only the role of mixing the materials, the two methods There is an incomparable difference in mixing efficiency between the livers, and the mixing method according to the present invention is much better.
또한, 상기 외통(412)의 외측으로 돌출된 어느 일측의 내통(420)에 설치되어 내통(420)을 회전시키는 동력전달부(440)가 구비된다.In addition, the power transmission unit 440 is installed in the inner cylinder 420 of any one side protruding to the outside of the outer cylinder 412 is provided to rotate the inner cylinder 420.
여기서, 상기 동력전달부(440)는 재료를 전단마찰에 의해 앞으로 이동시킬 때, 내통(420)을 후진시키려는 힘이 발생하는 데 이를 막아주는 테이크 베어링, 모터의 회전속도는 감소시키나 회전 힘은 몇 배로 배가시키는 감속기 그리고 감속기를 회전시키는 모터가 모두 포함된 것을 지칭한다. Here, the power transmission unit 440, when moving the material forward by the shear friction, the force generated to reverse the inner cylinder 420 is generated, which takes this to prevent the bearing, the rotational speed of the motor is reduced but the rotational force is a few It refers to a speed reducer that doubles and includes a motor that rotates the speed reducer.
나아가, 상기 내통(420)의 일측 외주면에 스프라켓(442)이 구비되고, 이 스프라켓(442)이 체인(444)에 의해 회전되도록 동력전달부(446)가 구비된다.Furthermore, a sprocket 442 is provided on one side outer circumferential surface of the inner cylinder 420, and a power transmission unit 446 is provided such that the sprocket 442 is rotated by the chain 444.
아울러, 상기 내통(420)의 외주면에는 풀리(미도시)를 형성하고, 이 풀리와 벨트(미도시)로 모터(446)를 연결시킬 수도 있으며, 이 이외에 내통(420)을 회전시킬 수 있는 모든 수단이 적용 가능하다.In addition, a pulley (not shown) may be formed on the outer circumferential surface of the inner cylinder 420, and the pulley and the belt (not shown) may be connected to the motor 446. In addition to this, all of the inner cylinder 420 may be rotated. Means are applicable.
그리고, 상기 내통(420)의 내측에 설치되어 열을 발산하여 외통(412)과 내통(420)의 사이로 공급되는 폐골재와 신골재가 용이하게 혼합이 이루어질 수 있도록 하는 가열부(450)가 구비된다.In addition, the heating unit 450 is installed inside the inner cylinder 420 to dissipate heat so that the waste aggregate and the new aggregate supplied between the outer cylinder 412 and the inner cylinder 420 can be easily mixed. do.
여기서, 상기 가열부(450)는 내통(420)의 내측에 길이 방향으로 다수개의 히터봉(452)이 구비되고, 이 히터봉(452)은 외부로부터 공급되는 전원공급수단에 의해 열을 발산하여 교반부재(430)에 의해 이동되는 혼합골재를 간접 가열하게 된다.Here, the heating unit 450 is provided with a plurality of heater rods 452 in the longitudinal direction on the inner side of the inner cylinder 420, the heater rods 452 to dissipate heat by the power supply means supplied from the outside Indirect heating of the mixed aggregate moved by the stirring member 430.
따라서, 상기 교반부재(430)에 의해 나선방향으로 이동하면서 폐골재와 신골재가 혼합되는 과정에서 가열부(450)에서 발산하는 열에 의해 간접 가열되게 되어 열교환이 이루어지게 되어 더욱 효과적으로 균일한 혼합과 균일한 피복이 이루어지게 된다.Therefore, while moving in a spiral direction by the stirring member 430 is indirectly heated by the heat emitted from the heating unit 450 in the process of mixing the waste aggregate and the new aggregate heat exchange is made more effectively uniform mixing and Uniform coating is achieved.
또한, 상기 내통(420)에는 가열부(450)에서 발산하는 열기에 의해 내통(420)의 일측으로 배출되는 폐열을 회수하는 폐열회수부(460)가 더 구비된다.In addition, the inner cylinder 420 is further provided with a waste heat recovery unit 460 for recovering waste heat discharged to one side of the inner cylinder 420 by the heat emitted from the heating unit 450.
여기서, 상기 폐열회수부(460)는 제1호퍼(414) 측의 내통(420)에 설치되는 회수관(462)이 구비된다.Here, the waste heat recovery unit 460 is provided with a recovery pipe 462 is installed in the inner cylinder 420 of the first hopper 414 side.
나아가, 상기 회수관(462)의 일측은 내통(420)의 내측과 연결되게 설치되고, 타측부는 외통(412)의 상부에 설치되어 폐골재가 투입되는 제1호퍼(414)의 외주면에 권취되게 된다.Further, one side of the recovery pipe 462 is installed to be connected to the inner side of the inner cylinder 420, the other side is installed on the upper portion of the outer cylinder 412 is wound on the outer circumferential surface of the first hopper 414 into which waste aggregate is introduced Will be.
따라서, 상기 내통(420)의 열기는 내통에 연결된 방향으로 회수되어 회수관(462)을 순환하여 외부로 배출되게 된다.Therefore, the heat of the inner cylinder 420 is recovered in the direction connected to the inner cylinder to circulate the recovery pipe 462 is discharged to the outside.
이때, 상기 회수관(462)을 순환하여 배출되는 열기에 의해 제1호퍼(414)에 권취된 회수관(462)을 폐열이 통과하는 과정에서 제1호퍼(414)로 투입되는 폐골재를 예비 가열한 상태로 투입되게 되어 더욱 효과적으로 혼합되므로, 혼합에 따른 효과가 상승하게 된다. At this time, the waste aggregate is introduced into the first hopper 414 in the process of waste heat passing through the recovery pipe 462 wound in the first hopper 414 by the heat discharged by circulating the recovery pipe 462. Since it is put in a heated state and mixed more effectively, the effect of mixing increases.
한편, 도 4에 도시된 바와 같이 상기 외통(412)의 배출구(418)를 통하여 배출된 아스콘을 공급받아 일정한 온도로 저장하고, 필요에 따라 운반용 덤프트럭에 배출시키는 저장사일로(510)가 구비된다.Meanwhile, as illustrated in FIG. 4, a storage silo 510 is provided to receive the ascon discharged through the discharge port 418 of the outer cylinder 412 and store it at a constant temperature, and to discharge it to a transport dump truck as necessary. .
이때, 상기 혼합부(410)에서 혼합됨과 동시에 가열되어 외통(412)의 배출구(418)로 배출되는 아스콘은 저장사일로(510)를 통하지 않고, 운반용 덤프트럭에 직접 적재하여 포장공사 등 공사 현장으로 운반할 수도 있다.At this time, the ascon mixed with the mixing unit 410 and heated and discharged to the outlet 418 of the outer cylinder 412 is loaded directly into the transport dump truck without passing through the storage silo 510 to a construction site such as a packaging work. You can also carry it.
이와 같이 구성된 본 발명에 따른 중앙식 연속 아스콘 생산장치에 대한 작용관계를 설명하면 다음과 같다.Referring to the working relationship for the central continuous ascon production apparatus according to the present invention configured as described above are as follows.
도 5 및 도 6은 본 발명에 따른 중앙식 연속 아스콘 생산장치의 작용관계를 보인 도면이다. 5 and 6 is a view showing the working relationship of the central continuous ascon production apparatus according to the present invention.
이에 도시된 바와 같이 본 발명에 따른 중앙식 연속 아스콘 생산장치(100)는 먼저, 도로공사 등을 할 때 발생된 폐아스콘을 수거하여 분쇄수단을 이용하여 분쇄한 후 분쇄된 폐골재를 입도 별로 분류하여 골재저장부(110)의 콜드빈(112)에 분리하여 각각 저장시킨다.As shown in the central continuous ascon production apparatus 100 according to the present invention, first, the waste ascon generated during the road construction, etc. to collect the pulverized by using a grinding means and then sorted the crushed waste aggregate by particle size By separating the stored in the cold bin 112 of the aggregate storage unit 110.
그리고, 골재를 입도별로 분류하여 골재저장부(110)의 콜드빈(112)에 치수별로 각각 저장시킬 수도 있으며, 콜드빈(112)의 개수를 늘려서 폐골재와 신골재를 각각 따로 콜드빈(112)에 저장하였다가 폐골재와 신골재의 입도별로 혼합비율에 따라 각각 적당량씩 콜드빈(112)의 하부에 구비된 배출조절구(114)에 의해 배출시킨 후 이 혼합골재를 이송컨베이어(212)를 통해 이송시킬 수도 있다.In addition, the aggregates may be classified by particle size and stored in the cold bins 112 of the aggregate storage unit 110 by dimensions, respectively, and by increasing the number of cold bins 112, the waste aggregates and the new aggregates are separately stored in the cold bins 112. ) And then discharged by the discharge control port 114 provided in the lower portion of the cold bin 112 according to the mixing ratio of the waste aggregate and the new aggregate by the particle size of each aggregate aggregate conveying conveyor (212) It can also be transferred via.
이 상태에서 아스콘을 생산하기 위하여 골재 종류와 입도가 서로 다른 골재가 배합 함량에 따라 콜드빈(112)의 하부에 구비된 배출조절구(114)를 통해 배출된다.In order to produce ascon in this state, aggregates having different aggregate types and particle sizes are discharged through the discharge control unit 114 provided at the lower portion of the cold bean 112 according to the blending content.
이와 같이 상기 콜드빈(112)으로부터 배출된 골재들은 이송컨베이어(212)의 상부로 떨어지게 되고, 이 상태에서 이송컨베이어(212)에 의해 혼합부(410)로 이송되게 된다.As such, the aggregates discharged from the cold bin 112 are dropped to the upper portion of the transfer conveyor 212, and in this state is transferred to the mixing unit 410 by the transfer conveyor 212.
이때, 상기 이송컨베이어(212)에 의해 이송되는 골재에 물성을 개선하기 위하여 개질첨가제 공급부(310)에서 이송중인 골재에 개질첨가제를 정량 공급한다.At this time, in order to improve the physical properties of the aggregate transported by the conveying conveyor 212, the reforming additive supply unit 310 supplies a fixed amount of the reforming additive to the transported aggregate.
그리고, 상기 이송컨베이어(212)에 의해 이송된 골재와 개질첨가제는 혼합부(410)의 제1호퍼(414)를 통해 외통(412)의 내측으로 공급되고, 외통(412)의 내측으로 공급된 폐골재는 동력전달부(440)의 모터(446)에 의해 회전하는 내통(420)의 외주면에 구비된 교반부재(430)에 의해 교반이 이루어지면서 외통(412)의 배출구(418) 방향으로 이동하게 된다.In addition, the aggregate and the reforming additive conveyed by the conveying conveyor 212 are supplied to the inside of the outer cylinder 412 through the first hopper 414 of the mixing unit 410, and is supplied to the inner side of the outer cylinder 412 The waste aggregate moves in the direction of the outlet 418 of the outer cylinder 412 while being agitated by the stirring member 430 provided on the outer circumferential surface of the inner cylinder 420 rotating by the motor 446 of the power transmission unit 440. Done.
이렇게, 폐골재와 신골재가 각각 분리되어 별개의 골재이송부(210)에 의해 이송될 경우에는 외통(412)의 제1호퍼(414)로 폐골재가, 외통(412)의 제2호퍼(416)로 신골재가 각각 투입되어 혼합부 내부에서 혼합이 될 수도 있다.Thus, when the waste aggregate and the new aggregate are separated and transferred by the separate aggregate transfer unit 210, the waste aggregate is the first hopper 414 of the outer cylinder 412, the second hopper 416 of the outer cylinder 412 New aggregates are added to each other and may be mixed inside the mixing unit.
그리고, 폐골재와 신골재의 혼합골재가 하나의 골재이송부(210)에 의해 이송될 경우에는 제1호퍼(414) 하나를 사용하여 혼합부(410) 내부로 공급할 수도 있다.When the mixed aggregate of waste aggregate and new aggregate is transferred by one aggregate transfer unit 210, the aggregate aggregate may be supplied into the mixing unit 410 using one first hopper 414.
이때, 상기 제3호퍼를 통해 액상의 재료가 투입되며, 외통(412)에 별도의 호퍼(미도시)를 다수개 형성하여 각각에 신규아스팔트, 재생첨가제 및 섬유재 등을 각기 따로 투입할 수도 있다.In this case, the liquid material is introduced through the third hopper, and a plurality of separate hoppers (not shown) may be formed in the outer cylinder 412, and new asphalt, regeneration additives, and fiber materials may be separately added to each of them. .
이와 같이 골재(폐골재, 신골재, 혹은 혼합골재)와 유기첨가제가 혼합부(410)의 초입에 공급되면 교반부재(430)가 전단마찰을 일으키며 골재와 유기첨가제를 나선방향으로 이송시키는 데, 이때 발생하는 마찰열과 내통(420)으로부터 전달되는 간접가열에 의해 가열 용융되고, 용융된 액체는 가열된 골재를 피복하고, 피복된 골재는 서로 혼합되면서 배출구(418)로 이동하게 된다.As such, when the aggregate (waste aggregate, new aggregate, or mixed aggregate) and the organic additive are supplied to the beginning of the mixing unit 410, the stirring member 430 causes shear friction and transfers the aggregate and the organic additive in the spiral direction. The molten liquid is heated and melted by friction heat generated and indirect heating transferred from the inner cylinder 420, and the molten liquid coats the heated aggregate, and the coated aggregate is mixed with each other to move to the outlet 418.
상기 재료의 이동시에 일정한 간격을 두고 바연속적으로 배치된 교반부재(430)는 이웃하는 교반부재(430)와의 사이에 전단이동이 없는 빈공간이 생긴다. 상기 빈 공간에 위치한 앞선 혼합골재는 전단이동을 할 수 없음으로 역류하게 되어 뒤따라 오는 재료와 만나 다시 전단이동을 일으켜 전진하게 됨으로서 재료의 혼합을 더욱 촉진시키는 역할을 하게 된다.The stirring member 430 continuously arranged at regular intervals at the time of movement of the material has an empty space without shear movement between neighboring stirring members 430. The preceding mixed aggregate located in the empty space is reversed due to the inability to shear movement and meets with the following material, which causes shearing movement to move forward to further promote the mixing of the materials.
즉, 전단마찰에 의한 혼합과 재료의 역류에 의한 혼합작용으로 효율적인 혼합이 이루어진다. That is, efficient mixing is achieved by mixing by shear friction and mixing by reverse flow of materials.
비연속적인에 교반부재(430)는 역류하는 혼합골재를 제외한 접촉면의 혼합골재만을 전단 이동시킴으로써, 내통(420)을 회전시키는 데 걸리는 동력전달부(440)의 부하를 경감시키는 역할도 한다.The discontinuous stirring member 430 also serves to reduce the load of the power transmission unit 440 that is required to rotate the inner cylinder 420 by shearing only the mixed aggregate of the contact surface excluding the mixed backflow aggregate.
상기에서, 재료의 전단마찰에 따른 혼합역할과 동력전달부(440)의 부하경감역할을 동시에 고려하여 교반부재(430)의 길이와 교반부재(430) 사이의 간격을 조절할 수 있다.In the above, the length of the stirring member 430 and the distance between the stirring member 430 may be adjusted in consideration of the mixing role according to the shear friction of the material and the load reducing role of the power transmission unit 440 at the same time.
또한, 상기 내통(420)의 회전에 따른 교반부재(430)의 전단마찰에 의해 골재 및 유기첨가제(신규 아스팔트, 개질첨가제, 새생첨가제 등)가 혼합되면서 이동될 때 가열부(450)의 히터봉(452)에서 열이 발산되고, 열은 간접 가열로 재료에 전달되어 재료 중의 유기첨가제를 녹여 균일한 혼합액체를 형성하게 되고, 이 액체는 교반부재(430), 골재, 내통(420)의 외주, 외통(412)의 내주를 피복함으로서 마찰을 감소시키는 윤활제역할을 한다.In addition, the heater rod of the heating unit 450 when the aggregate and the organic additives (new asphalt, modified additives, new additives, etc.) are moved while mixing by shear friction of the stirring member 430 according to the rotation of the inner cylinder 420 Heat is dissipated at 452, and heat is transferred to the material by indirect heating to melt organic additives in the material to form a uniform mixed liquid, which is the outer circumference of the stirring member 430, aggregate, and inner cylinder 420. By covering the inner circumference of the outer cylinder 412, it serves as a lubricant to reduce friction.
이러한 윤활역할은 골재와 교반부재(430), 골재와, 골재와 내통(420) 외주면 간의 마찰을 줄여서 내통(420)의 회전을 용이하게 하며, 재료의 균일한 혼합을 촉진시키며 교반부재(430)에 의해 나선방향으로 이동하게 된다.This lubrication role facilitates the rotation of the inner cylinder 420 by reducing the friction between the aggregate and the stirring member 430, the aggregate, and the outer peripheral surface of the aggregate and the inner cylinder 420, promotes uniform mixing of the material and the stirring member 430 It moves in the spiral direction by.
이렇게, 상기 내통(420)의 회전에 의해 나선방향으로 이동하면서 혼합이 이루어진 골재는 외통(412)의 배출구(418)로 배출되게 되게 된다.Thus, the aggregate made by mixing while moving in the spiral direction by the rotation of the inner cylinder 420 is to be discharged to the outlet 418 of the outer cylinder 412.
따라서, 상기 외통(412)의 배출구(418)로 배출된 아스콘은 운반용 덤프트럭에 적재 운반하여 도로 포장공사 등에 재사용할 수도 있고, 별도의 저장사일로(510)에 저장된 후 필요에 따라 운반용 덤프트럭에 적재 운반하여 도로 포장공사 등에 사용할 수 있게 된다.Therefore, ascon discharged to the outlet 418 of the outer cylinder 412 may be transported in a transport dump truck to be reused for road pavement construction, etc., or stored in a separate storage silo 510 to a transport dump truck as needed. It can be used for road pavement construction by carrying and loading.
또한, 상기 내통(420)의 내측으로부터 배출되는 폐열은 회수관(462)을 통하여 순환하여 외통의 제1호퍼(414)를 가열시켜 제1호퍼(414)로 투입되는 폐골재를 예비가열함으로써, 내통(420)의 외부로 배출되는 폐열을 재활용하게 되어 열손실을 방지할 수 있게 된다.In addition, the waste heat discharged from the inside of the inner cylinder 420 is circulated through the recovery pipe 462 to heat the first hopper 414 of the outer cylinder to preheat the waste aggregate introduced into the first hopper 414, The waste heat discharged to the outside of the inner cylinder 420 can be recycled to prevent heat loss.
도 7은 본 발명에 따른 혼합부의 다른 실시 예를 보인 도면이다.7 is a view showing another embodiment of the mixing unit according to the present invention.
이에 도시된 바와 같이 상기 내통(420)의 일측부, 즉 외통(412)의 제1호퍼(414)가 형성된 방향은 직경이 작은 관(420a)으로 외통(412)의 배출구(418)가 형성된 방향은 직경이 큰 관(420c)으로, 직경이 작은 관(420a)과 큰 관(420c) 사이에는 직경이 점진적으로 증가하는 전환관(420b)이 형성된다.As shown therein, one side portion of the inner cylinder 420, that is, the direction in which the first hopper 414 of the outer cylinder 412 is formed is a direction in which the outlet 418 of the outer cylinder 412 is formed by a small diameter pipe 420a. Silver is a large diameter tube 420c, and a conversion tube 420b whose diameter gradually increases is formed between the small diameter tube 420a and the large diameter tube 420c.
여기서, 각 관의 길이와 각도는 설계자의 설계에 따라 조정이 가능하다. 내통을 3부분으로 나눈 이유는 각기 다른 기능을 수행하기 위해서이다. 직경이 작은 관(420a) 부분은 재료의 투입과 이송을 원활히 하기 위해, 전환 관(420b) 부분은 이송된 재료의 압축과 압축 재료에 강력한 전단마찰을 일으켜 용융을 가속화하기 위해, 그리고 큰 관(420c) 부분은 용융의 완성과 균일혼합을 이룬 후 혼합재료를 배출하기 위해 각각 고안되는 특징이 있다.Here, the length and angle of each tube can be adjusted according to the design of the designer. The reason for dividing the inner cylinder into three parts is to perform different functions. The small diameter tube 420a portion facilitates the feeding and conveying of the material, and the conversion tube 420b portion causes strong shear friction on the compressed and compressed material of the conveyed material to accelerate the melting, and the large tube ( The portion 420c is characterized in that it is designed to discharge the mixed material after completion of the melting and homogeneous mixing.
이와 같이 구성된 본 발명에 따른 중앙식 연속 아스콘 생산장치에 대한 작용관계는 전자에서와 동일한 방법에 의해 이루어지는 것으로, 여기에서는 작용관계에 대한 설명은 생략한다.The working relationship for the central continuous ascon production apparatus according to the present invention configured as described above is made by the same method as in the former, the description of the working relationship is omitted here.
도 8은 본 발명에 따른 혼합부의 또 다른 실시예를 보인 도면이다.8 is a view showing another embodiment of the mixing unit according to the present invention.
이에 도시된 바와 같이 상기 혼합부(410)의 내통(420)에 설치되는 가열부(450)는 내통(420)의 일측부에 화염구가 위치되게 버너(454)가 구비된다.As shown therein, the heating unit 450 installed in the inner cylinder 420 of the mixing unit 410 is provided with a burner 454 such that a flame opening is positioned at one side of the inner cylinder 420.
이와 같이 구성된 본 발명에 따른 중앙식 연속 아스콘 생산장치에 대한 작용관계는 전자에서와 동일한 방법에 의해 이루어지는 것으로, 여기에서는 작용관계에 대한 설명은 생략한다.The working relationship for the central continuous ascon production apparatus according to the present invention configured as described above is made by the same method as in the former, the description of the working relationship is omitted here.
다만, 상기 내통(420)의 회전에 의해 외통의 제1,2,3호퍼(414)(416)(417)로 각각 공급되는 폐골재, 신골재 및 유기첨가제가 교반부재(430)에 의해 교반이 이루어지면서 나선방향으로 이동될 때 버너(454)에서 발산되는 화염에 의해 발생된 열기가 혼합재료에 간접적으로 전달되어 열교환이 이루어지게 된다. However, waste aggregates, new aggregates and organic additives supplied to the first, second and third hoppers 414, 416 and 417 of the outer cylinder by the rotation of the inner cylinder 420 are stirred by the stirring member 430. This is done while the heat generated by the flame emitted from the burner 454 when moved in the spiral direction is indirectly transferred to the mixed material to the heat exchange.
종래의 버너 가열방식은 가열부와 골재이송부가 한 건조통 내부에서 이루어짐으로 엄밀한 의미에서 간접가열이기 보다는 직접가열에 가깝다. The conventional burner heating method is closer to direct heating rather than indirect heating in a strict sense, since the heating part and the aggregate conveying part are made inside a drying container.
다만, 화염에 재료가 직접 닿지 않는다는 점에서 간접가열이라고 주장하고 있으나 가열에 의한 재료의 온도상승을 제어하기가 어렵다. However, it is indirect heating in that the material does not directly touch the flame, but it is difficult to control the temperature rise of the material by heating.
따라서, 국부적인 산화노화에 의한 재료손상이 예측된다. 이에 반하여 본 발명은 이중 통으로 구성되어 재료는 내통의 위주에서 이송되고, 가열은 내통의 내면에서 시작하여 위주면의 재료로 열전달이 이루어지도록 함으로서 재료이송과 열전달이 완전히 분리된다. Therefore, material damage due to local oxidation aging is predicted. In contrast, the present invention is composed of a double cylinder material is transferred in the inner cylinder, the heating is started from the inner surface of the inner cylinder to transfer the heat to the material of the peripheral surface is completely separated material transfer and heat transfer.
이로 인해 전달되는 열을 사전에 온도센서로 감지하여 정확한 온도제어가 가능하도록 구성되는 특징이 있다. 폐골재에 부착된 폐 혹은 신규아스팔트는 열에 의해 산소와 반응하여 유연성을 상실하고, 딱딱해지며 노화되는 데 이를 산화노화라 한다. 산화노화가 많이 될수록 재료는 딱딱해지고 딱딱해진 재료는 쉽게 균열을 발생시킴으로 수명이 짧아진다. 이러한 열에 의한 아스팔트의 산화노화는 온도가 높을수록 급속히 증가함으로 과다한 산화노화를 피하기 위해 가급적 직접적인 가열은 피하려고 한다. 따라서 본 발명에서처럼 재료이송과 열 발생원이 분리되어 완전한 간접가열을 이루는 것이 가장 이상적이라 할 수 있다. Due to this, there is a feature that is configured to enable accurate temperature control by detecting the heat transferred in advance with a temperature sensor. Lung or new asphalt attached to the waste aggregate loses flexibility, hardens and ages by reacting with oxygen by heat, which is called aging. The more oxidative aging is, the harder the material becomes and the harder the material is, the easier it is to crack and shorten its lifetime. Oxidation aging of asphalt caused by heat increases rapidly at higher temperatures, and therefore, direct heating is avoided as much as possible to avoid excessive oxidation. Therefore, as in the present invention, it is most ideal that the material transfer and the heat generating source are separated to achieve complete indirect heating.

나아가, 상기 외통(412)의 내측에는 중앙부 길이 방향으로 내통(420)이 구비된다.Further, an inner cylinder 420 is provided in the longitudinal direction of the central portion of the outer cylinder 412.
이때, 상기 내통(420)은 고정된 외통(412)의 양측부로 돌출되게 구비되고, 내통(420)은 외통(412)으로부터 분리되어 회전이 가능하게 설치된다. At this time, the inner cylinder 420 is provided to protrude to both sides of the fixed outer cylinder 412, the inner cylinder 420 is separated from the outer cylinder 412 is installed to enable rotation.
아울러, 상기 내통(420)의 외주면에는 압출스크루 방향으로 배열되게 다수개의 교반부재(430)가 구비된다.In addition, the outer circumferential surface of the inner cylinder 420 is provided with a plurality of stirring members 430 to be arranged in the extrusion screw direction.
이때, 상기 교반부재(430)는 이웃하는 교반부재(430)와 소정의 간격을 유지하면서 압출스크루의 나선방향으로 내통(420)의 외주면에 볼트 등 고정수단에 의해 고정, 된다.At this time, the stirring member 430 is fixed to the outer circumferential surface of the inner cylinder 420 in the spiral direction of the extrusion screw by a fixing means such as a bolt while maintaining a predetermined interval with the neighboring stirring member 430.
그리고, 상기 교반부재(430)는 일정한 길이를 가진 압출 스크루의 플라이트 형상을 하고 있으나, 압출스크루의 플라이트는 고분자용융액체의 혼합을 취급하는 데 반하여, 본 발명에서는 큰 골재(최대 40mm 이하)를 취급해야 함으로, 내통(420)의 반경과 골재크기를 고려하여 플라이트의 제반 치수가 크게 증가된 것이어야 한다. In addition, the stirring member 430 has a flight shape of an extruded screw having a predetermined length, whereas the flight of the extruded screw handles mixing of the molten polymer solution, whereas the present invention handles large aggregates (up to 40 mm or less). Should be, the overall dimensions of the flight should be greatly increased in consideration of the radius and the aggregate size of the inner cylinder (420).
또한, 골재와 접촉하는 교반부재(430)의 접촉면은 액체가 아니라 골재를 취급함으로 골재와의 미끄러짐을 방지해야 한다. In addition, the contact surface of the stirring member 430 in contact with the aggregate should prevent the slip with the aggregate by handling the aggregate, not the liquid.
이때, 미끄러짐이 심하면 교반부재가 헛돌게 되어 골재이송을 할 수 없음으로 이를 방지하기 위하여 교반부재(430)의 접촉면에 엠보싱을 만들거나, 그루빙을 내거나, 홈이 파여 있거나 오목홈(430)이 만들어져있거나 혹은 다양한 패턴으로 가공된 것이어야 한다. At this time, if the slip is severe, the stirring member is in vain and the aggregate transfer is not possible to prevent the embossing, grooving, grooved or recessed groove 430 to prevent the contact surface of the stirring member 430 It must be made or processed in various patterns.
이렇게, 상기 교반부재(430)는 골재와의 마찰로 인해 마모되기 쉬움으로 이를 방지하도록 내마모강으로 제조되어야 한다. Thus, the stirring member 430 is to be made of wear-resistant steel to prevent this due to the wear and tear due to friction with the aggregate.
본 발명에서처럼 교반부재가 전단마찰에 의해 재료를 나선방향으로 이송하는 방법은, 기존장비에서처럼 회전원통 내벽에 경사져 달린 엽지날개가 재료를 이송하는 방법과는 혼합효율 면에서 큰 차이가 있다. As in the present invention, the method of conveying the material in the spiral direction by the shear friction in the stirring member, as in the existing equipment, has a big difference in terms of mixing efficiency from the method in which the blade blades inclined to the inner wall of the rotating cylinder convey the material.
기존방법에서는 혼합기 원통이 회전하게 되면 내벽에 붙은 엽지날개의 홈에 원통밑면의 재료를 퍼 올려서 상부에서 엽지날개가 거꾸로 되어 홈의 재료가 중력에 의해 날개가 부착된 각도로 뿌려짐으로서 재료의 이송과 혼합을 이루게 되지만, 본 발명에서의 교반부재는 압출스크루 식의 전단마찰에 의해 재료 간의 강력한 혼합을 유도하면서 나선방향으로 재료를 이송시킨다. In the conventional method, when the mixer cylinder is rotated, the material of the bottom of the cylinder is spread in the groove of the blade blade attached to the inner wall so that the blade blade is inverted from the top, so that the material of the groove is scattered at the angle of the wing attached by gravity to transfer the material. Although the mixing with the present invention, the stirring member in the present invention transfers the material in the spiral direction while inducing strong mixing between the materials by the shear screw of the extrusion screw type.
즉, 재료의 혼합기능을 고려할 때 본 발명의 교반부재(430)는 재료간의 강력한 전단마찰을 유도하여 혼합시키는 반면에, 종래의 엽지날개는 단순히 재료를 섞어주는 역할만을 하는 차이가 있기 때문에 두 방법 간에는 비교할 수 없을 만큼 큰 혼합효율성의 차이가 존재하며, 본 발명에 의한 혼합방법이 훨씬 우수하다.That is, when considering the mixing function of the material, the stirring member 430 of the present invention induces strong shear friction between the materials, while mixing, whereas the conventional leaf blades have only the role of mixing the materials, the two methods There is an incomparable difference in mixing efficiency between the livers, and the mixing method according to the present invention is much better.
또한, 상기 외통(412)의 외측으로 돌출된 어느 일측의 내통(420)에 설치되어 내통(420)을 회전시키는 동력전달부(440)가 구비된다.In addition, the power transmission unit 440 is installed in the inner cylinder 420 of any one side protruding to the outside of the outer cylinder 412 is provided to rotate the inner cylinder 420.
여기서, 상기 동력전달부(440)는 재료를 전단마찰에 의해 앞으로 이동시킬 때, 내통(420)을 후진시키려는 힘이 발생하는 데 이를 막아주는 테이크 베어링, 모터의 회전속도는 감소시키나 회전 힘은 몇 배로 배가시키는 감속기 그리고 감속기를 회전시키는 모터가 모두 포함된 것을 지칭한다. Here, the power transmission unit 440, when moving the material forward by the shear friction, the force generated to reverse the inner cylinder 420 is generated, which takes this to prevent the bearing, the rotational speed of the motor is reduced but the rotational force is a few It refers to a speed reducer that doubles and includes a motor that rotates the speed reducer.

In addition to this, all of the inner cylinder 420 may be rotated. Means are applicable.
그리고, 상기 내통(420)의 내측에 설치되어 열을 발산하여 외통(412)과 내통(420)의 사이로 공급되는 폐골재와 신골재가 용이하게 혼합이 이루어질 수 있도록 하는 가열부(450)가 구비된다.In addition, the heating unit 450 is installed inside the inner cylinder 420 to dissipate heat so that the waste aggregate and the new aggregate supplied between the outer cylinder 412 and the inner cylinder 420 can be easily mixed. do.
여기서, 상기 가열부(450)는 내통(420)의 내측에 길이 방향으로 다수개의 히터봉(452)이 구비되고, 이 히터봉(452)은 외부로부터 공급되는 전원공급수단에 의해 열을 발산하여 교반부재(430)에 의해 이동되는 혼합골재를 간접 가열하게 된다.Here, the heating unit 450 is provided with a plurality of heater rods 452 in the longitudinal direction on the inner side of the inner cylinder 420, the heater rods 452 to dissipate heat by the power supply means supplied from the outside Indirect heating of the mixed aggregate moved by the stirring member 430.
따라서, 상기 교반부재(430)에 의해 나선방향으로 이동하면서 폐골재와 신골재가 혼합되는 과정에서 가열부(450)에서 발산하는 열에 의해 간접 가열되게 되어 열교환이 이루어지게 되어 더욱 효과적으로 균일한 혼합과 균일한 피복이 이루어지게 된다.Therefore, while moving in a spiral direction by the stirring member 430 is indirectly heated by the heat emitted from the heating unit 450 in the process of mixing the waste aggregate and the new aggregate heat exchange is made more effectively uniform mixing and Uniform coating is achieved.
또한, 상기 내통(420)에는 가열부(450)에서 발산하는 열기에 의해 내통(420)의 일측으로 배출되는 폐열을 회수하는 폐열회수부(460)가 더 구비된다.In addition, the inner cylinder 420 is further provided with a waste heat recovery unit 460 for recovering waste heat discharged to one side of the inner cylinder 420 by the heat emitted from the heating unit 450.
여기서, 상기 폐열회수부(460)는 제1호퍼(414) 측의 내통(420)에 설치되는 회수관(462)이 구비된다.Here, the waste heat recovery unit 460 is provided with a recovery pipe 462 is installed in the inner cylinder 420 of the first hopper 414 side.
나아가, 상기 회수관(462)의 일측은 내통(420)의 내측과 연결되게 설치되고, 타측부는 외통(412)의 상부에 설치되어 폐골재가 투입되는 제1호퍼(414)의 외주면에 권취되게 된다.Further, one side of the recovery pipe 462 is installed to be connected to the inner side of the inner cylinder 420, the other side is installed on the upper portion of the outer cylinder 412 is wound on the outer circumferential surface of the first hopper 414 into which waste aggregate is introduced Will be.
따라서, 상기 내통(420)의 열기는 내통에 연결된 방향으로 회수되어 회수관(462)을 순환하여 외부로 배출되게 된다.Therefore, the heat of the inner cylinder 420 is recovered in the direction connected to the inner cylinder to circulate the recovery pipe 462 is discharged to the outside.
이때, 상기 회수관(462)을 순환하여 배출되는 열기에 의해 제1호퍼(414)에 권취된 회수관(462)을 폐열이 통과하는 과정에서 제1호퍼(414)로 투입되는 폐골재를 예비 가열한 상태로 투입되게 되어 더욱 효과적으로 혼합되므로, 혼합에 따른 효과가 상승하게 된다. At this time, the waste aggregate is introduced into the first hopper 414 in the process of waste heat passing through the recovery pipe 462 wound in the first hopper 414 by the heat discharged by circulating the recovery pipe 462.

이렇게, 폐골재와 신골재가 각각 분리되어 별개의 골재이송부(210)에 의해 이송될 경우에는 외통(412)의 제1호퍼(414)로 폐골재가, 외통(412)의 제2호퍼(416)로 신골재가 각각 투입되어 혼합부 내부에서 혼합이 될 수도 있다.Thus, when the waste aggregate and the new aggregate are separated and transferred by the separate aggregate transfer unit 210, the waste aggregate is the first hopper 414 of the outer cylinder 412, the second hopper 416 of the outer cylinder 412 New aggregates are added to each other and may be mixed inside the mixing unit.
그리고, 폐골재와 신골재의 혼합골재가 하나의 골재이송부(210)에 의해 이송될 경우에는 제1호퍼(414) 하나를 사용하여 혼합부(410) 내부로 공급할 수도 있다.When the mixed aggregate of waste aggregate and new aggregate is transferred by one aggregate transfer unit 210, the aggregate aggregate may be supplied into the mixing unit 410 using one first hopper 414.
이때, 상기 제3호퍼를 통해 액상의 재료가 투입되며, 외통(412)에 별도의 호퍼(미도시)를 다수개 형성하여 각각에 신규아스팔트, 재생첨가제 및 섬유재 등을 각기 따로 투입할 수도 있다.In this case, the liquid material is introduced through the third hopper, and a plurality of separate hoppers (not shown) may be formed in the outer cylinder 412, and new asphalt, regeneration additives, and fiber materials may be separately added to each of them. .
이와 같이 골재(폐골재, 신골재, 혹은 혼합골재)와 유기첨가제가 혼합부(410)의 초입에 공급되면 교반부재(430)가 전단마찰을 일으키며 골재와 유기첨가제를 나선방향으로 이송시키는 데, 이때 발생하는 마찰열과 내통(420)으로부터 전달되는 간접가열에 의해 가열 용융되고, 용융된 액체는 가열된 골재를 피복하고, 피복된 골재는 서로 혼합되면서 배출구(418)로 이동하게 된다.As such, when the aggregate (waste aggregate, new aggregate, or mixed aggregate) and the organic additive are supplied to the beginning of the mixing unit 410, the stirring member 430 causes shear friction and transfers the aggregate and the organic additive in the spiral direction. The molten liquid is heated and melted by friction heat generated and indirect heating transferred from the inner cylinder 420, and the molten liquid coats the heated aggregate, and the coated aggregate is mixed with each other to move to the outlet 418.
상기 재료의 이동시에 일정한 간격을 두고 바연속적으로 배치된 교반부재(430)는 이웃하는 교반부재(430)와의 사이에 전단이동이 없는 빈공간이 생긴다. 상기 빈 공간에 위치한 앞선 혼합골재는 전단이동을 할 수 없음으로 역류하게 되어 뒤따라 오는 재료와 만나 다시 전단이동을 일으켜 전진하게 됨으로서 재료의 혼합을 더욱 촉진시키는 역할을 하게 된다.The stirring member 430 continuously arranged at regular intervals at the time of movement of the material has an empty space without shear movement between neighboring stirring members 430. The preceding mixed aggregate located in the empty space is reversed due to the inability to shear movement and meets with the following material, which causes shearing movement to move forward to further promote the mixing of the materials.
즉, 전단마찰에 의한 혼합과 재료의 역류에 의한 혼합작용으로 효율적인 혼합이 이루어진다. That is, efficient mixing is achieved by mixing by shear friction and mixing by reverse flow of materials.
비연속적인에 교반부재(430)는 역류하는 혼합골재를 제외한 접촉면의 혼합골재만을 전단 이동시킴으로써, 내통(420)을 회전시키는 데 걸리는 동력전달부(440)의 부하를 경감시키는 역할도 한다.The discontinuous stirring member 430 also serves to reduce the load of the power transmission unit 440 that is required to rotate the inner cylinder 420 by shearing only the mixed aggregate of the contact surface excluding the mixed backflow aggregate.
상기에서, 재료의 전단마찰에 따른 혼합역할과 동력전달부(440)의 부하경감역할을 동시에 고려하여 교반부재(430)의 길이와 교반부재(430) 사이의 간격을 조절할 수 있다.In the above, the length of the stirring member 430 and the distance between the stirring member 430 may be adjusted in consideration of the mixing role according to the shear friction of the material and the load reducing role of the power transmission unit 440 at the same time.
또한, 상기 내통(420)의 회전에 따른 교반부재(430)의 전단마찰에 의해 골재 및 유기첨가제(신규 아스팔트, 개질첨가제, 새생첨가제 등)가 혼합되면서 이동될 때 가열부(450)의 히터봉(452)에서 열이 발산되고, 열은 간접 가열로 재료에 전달되어 재료 중의 유기첨가제를 녹여 균일한 혼합액체를 형성하게 되고, 이 액체는 교반부재(430), 골재, 내통(420)의 외주, 외통(412)의 내주를 피복함으로서 마찰을 감소시키는 윤활제역할을 한다.In addition, the heater rod of the heating unit 450 when the aggregate and the organic additives (new asphalt, modified additives, new additives, etc.) are moved while mixing by shear friction of the stirring member 430 according to the rotation of the inner cylinder 420 Heat is dissipated at 452, and heat is transferred to the material by indirect heating to melt organic additives in the material to form a uniform mixed liquid, which is the outer circumference of the stirring member 430, aggregate, and inner cylinder 420. By covering the inner circumference of the outer cylinder 412, it serves as a lubricant to reduce friction.
이러한 윤활역할은 골재와 교반부재(430), 골재와, 골재와 내통(420) 외주면 간의 마찰을 줄여서 내통(420)의 회전을 용이하게 하며, 재료의 균일한 혼합을 촉진시키며 교반부재(430)에 의해 나선방향으로 이동하게 된다.This lubrication role facilitates the rotation of the inner cylinder 420 by reducing the friction between the aggregate and the stirring member 430, the aggregate, and the outer peripheral surface of the aggregate and the inner cylinder 420, promotes uniform mixing of the material and the stirring member 430 It moves in the spiral direction by.
이렇게, 상기 내통(420)의 회전에 의해 나선방향으로 이동하면서 혼합이 이루어진 골재는 외통(412)의 배출구(418)로 배출되게 되게 된다.Thus, the aggregate made by mixing while moving in the spiral direction by the rotation of the inner cylinder 420 is to be discharged to the outlet 418 of the outer cylinder 412.
따라서, 상기 외통(412)의 배출구(418)로 배출된 아스콘은 운반용 덤프트럭에 적재 운반하여 도로 포장공사 등에 재사용할 수도 있고, 별도의 저장사일로(510)에 저장된 후 필요에 따라 운반용 덤프트럭에 적재 운반하여 도로 포장공사 등에 사용할 수 있게 된다.Therefore, ascon discharged to the outlet 418 of the outer cylinder 412 may be transported in a transport dump truck to be reused for road pavement construction, etc., or stored in a separate storage silo 510 to a transport dump truck as needed. It can be used for road pavement construction by carrying and loading.
또한, 상기 내통(420)의 내측으로부터 배출되는 폐열은 회수관(462)을 통하여 순환하여 외통의 제1호퍼(414)를 가열시켜 제1호퍼(414)로 투입되는 폐골재를 예비가열함으로써, 내통(420)의 외부로 배출되는 폐열을 재활용하게 되어 열손실을 방지할 수 있게 된다.In addition, the waste heat discharged from the inside of the inner cylinder 420 is circulated through the recovery pipe 462 to heat the first hopper 414 of the outer cylinder to preheat the waste aggregate introduced into the first hopper 414, The waste heat discharged to the outside of the inner cylinder 420 can be recycled to prevent heat loss.
도 7은 본 발명에 따른 혼합부의 다른 실시 예를 보인 도면이다.7 is a view showing another embodiment of the mixing unit according to the present invention.
이에 도시된 바와 같이 상기 내통(420)의 일측부, 즉 외통(412)의 제1호퍼(414)가 형성된 방향은 직경이 작은 관(420a)으로 외통(412)의 배출구(418)가 형성된 방향은 직경이 큰 관(420c)으로, 직경이 작은 관(420a)과 큰 관(420c) 사이에는 직경이 점진적으로 증가하는 전환관(420b)이 형성된다.As shown therein, one side portion of the inner cylinder 420, that is, the direction in which the first hopper 414 of the outer cylinder 412 is formed is a direction in which the outlet 418 of the outer cylinder 412 is formed by a small diameter pipe 420a. Silver is a large diameter tube 420c, and a conversion tube 420b whose diameter gradually increases is formed between the small diameter tube 420a and the large diameter tube 420c.
여기서, 각 관의 길이와 각도는 설계자의 설계에 따라 조정이 가능하다. 내통을 3부분으로 나눈 이유는 각기 다른 기능을 수행하기 위해서이다. 직경이 작은 관(420a) 부분은 재료의 투입과 이송을 원활히 하기 위해, 전환 관(420b) 부분은 이송된 재료의 압축과 압축 재료에 강력한 전단마찰을 일으켜 용융을 가속화하기 위해, 그리고 큰 관(420c) 부분은 용융의 완성과 균일혼합을 이룬 후 혼합재료를 배출하기 위해 각각 고안되는 특징이 있다.Here, the length and angle of each tube can be adjusted according to the design of the designer. The reason for dividing the inner cylinder into three parts is to perform different functions. The small diameter tube 420a portion facilitates the feeding and conveying of the material, and the conversion tube 420b portion causes strong shear friction on the compressed and compressed material of the conveyed material to accelerate the melting, and the large tube ( The portion 420c is characterized in that it is designed to discharge the mixed material after completion of the melting and homogeneous mixing.
이와 같이 구성된 본 발명에 따른 중앙식 연속 아스콘 생산장치에 대한 작용관계는 전자에서와 동일한 방법에 의해 이루어지는 것으로, 여기에서는 작용관계에 대한 설명은 생략한다.The working relationship for the central continuous ascon production apparatus according to the present invention configured as described above is made by the same method as in the former, the description of the working relationship is omitted here.
도 8은 본 발명에 따른 혼합부의 또 다른 실시예를 보인 도면이다.8 is a view showing another embodiment of the mixing unit according to the present invention.
이에 도시된 바와 같이 상기 혼합부(410)의 내통(420)에 설치되는 가열부(450)는 내통(420)의 일측부에 화염구가 위치되게 버너(454)가 구비된다.As shown therein, the heating unit 450 installed in the inner cylinder 420 of the mixing unit 410 is provided with a burner 454 such that a flame opening is positioned at one side of the inner cylinder 420.
이와 같이 구성된 본 발명에 따른 중앙식 연속 아스콘 생산장치에 대한 작용관계는 전자에서와 동일한 방법에 의해 이루어지는 것으로, 여기에서는 작용관계에 대한 설명은 생략한다.The working relationship for the central continuous ascon production apparatus according to the present invention configured as described above is made by the same method as in the former, the description of the working relationship is omitted here.
다만, 상기 내통(420)의 회전에 의해 외통의 제1,2,3호퍼(414)(416)(417)로 각각 공급되는 폐골재, 신골재 및 유기첨가제가 교반부재(430)에 의해 교반이 이루어지면서 나선방향으로 이동될 때 버너(454)에서 발산되는 화염에 의해 발생된 열기가 혼합재료에 간접적으로 전달되어 열교환이 이루어지게 된다. However, waste aggregates, new aggregates and organic additives supplied to the first, second and third hoppers 414, 416 and 417 of the outer cylinder by the rotation of the inner cylinder 420 are stirred by the stirring member 430. This is done while the heat generated by the flame emitted from the burner 454 when moved in the spiral direction is indirectly transferred to the mixed material to the heat exchange.
종래의 버너 가열방식은 가열부와 골재이송부가 한 건조통 내부에서 이루어짐으로 엄밀한 의미에서 간접가열이기 보다는 직접가열에 가깝다. The conventional burner heating method is closer to direct heating rather than indirect heating in a strict sense, since the heating part and the aggregate conveying part are made inside a drying container.
다만, 화염에 재료가 직접 닿지 않는다는 점에서 간접가열이라고 주장하고 있으나 가열에 의한 재료의 온도상승을 제어하기가 어렵다. However, it is indirect heating in that the material does not directly touch the flame, but it is difficult to control the temperature rise of the material by heating.
따라서, 국부적인 산화노화에 의한 재료손상이 예측된다. 이에 반하여 본 발명은 이중 통으로 구성되어 재료는 내통의 위주에서 이송되고, 가열은 내통의 내면에서 시작하여 위주면의 재료로 열전달이 이루어지도록 함으로서 재료이송과 열전달이 완전히 분리된다. Therefore, material damage due to local oxidation aging is predicted. In contrast, the present invention is composed of a double cylinder material is transferred in the inner cylinder, the heating is started from the inner surface of the inner cylinder to transfer the heat to the material of the peripheral surface is completely separated material transfer and heat transfer.
이로 인해 전달되는 열을 사전에 온도센서로 감지하여 정확한 온도제어가 가능하도록 구성되는 특징이 있다. 폐골재에 부착된 폐 혹은 신규아스팔트는 열에 의해 산소와 반응하여 유연성을 상실하고, 딱딱해지며 노화되는 데 이를 산화노화라 한다. 산화노화가 많이 될수록 재료는 딱딱해지고 딱딱해진 재료는 쉽게 균열을 발생시킴으로 수명이 짧아진다. 이러한 열에 의한 아스팔트의 산화노화는 온도가 높을수록 급속히 증가함으로 과다한 산화노화를 피하기 위해 가급적 직접적인 가열은 피하려고 한다. 따라서 본 발명에서처럼 재료이송과 열 발생원이 분리되어 완전한 간접가열을 이루는 것이 가장 이상적이라 할 수 있다. Due to this, there is a feature that is configured to enable accurate temperature control by detecting the heat transferred in advance with a temperature sensor. Lung or new asphalt attached to the waste aggregate loses flexibility, hardens and ages by reacting with oxygen by heat, which is called aging. The more oxidative aging is, the harder the material becomes and the harder the material is, the easier it is to crack and shorten its lifetime. Oxidation aging of asphalt caused by heat increases rapidly at higher temperatures, and therefore, direct heating is avoided as much as possible to avoid excessive oxidation. Therefore, as in the present invention, it is most ideal that the material transfer and the heat generating source are separated to achieve complete indirect heating.
도 9는 본 발명에 따른 혼합부의 또 다른 실시예를 보인 도면이다.9 is a view showing another embodiment of the mixing unit according to the present invention.
이에 도시된 바와 같이 상기 버너가 일측에 설치된 내통(420)의 내측부에는 일정 간격을 유지하며 다수개의 칸막이(422)가 구비되고, 이 각각의 칸막이(422)에는 다수개의 통공(424)이 형성된다.As shown therein, a plurality of partitions 422 are provided on the inner side of the inner cylinder 420 provided at one side of the burner, and a plurality of through holes 424 are formed in each of the partitions 422. .
이와 같이 구성된 본 발명에 따른 중앙식 연속 아스콘 생산장치에 대한 작용관계는 전자에서와 동일한 방법에 의해 이루어지는 것으로, 여기에서는 작용관계에 대한 설명은 생략한다.The working relationship for the central continuous ascon production apparatus according to the present invention configured as described above is made by the same method as in the former, the description of the working relationship is omitted here.
다만, 상기 버너(454)에서 발산되는 화염의 열기는 내통(420)의 내측에 구비된 칸막이(422)에 의해 정체되고, 이 정체된 열기는 순차적으로 칸막이(422)에 형성된 통공(424)을 통하여 이웃하는 칸막이(422) 사이로 이동하는 방식으로 하여 버너(454)가 설치된 내통(420)의 반대 방향으로 배출되도록 함으로써, 버너(454)에서 발산하는 화염에 의해 발생한 열기가 칸막이(422)에 의해 서서히 타측 방향으로 이동하게 되어 열효율을 극대화함과 동시에 혼합골재에 많은 열을 공급하여 혼합이 더욱 잘 이루어지게 된다. However, the heat of the flame emitted from the burner 454 is stagnated by the partition 422 provided on the inner side of the inner cylinder 420, and the stagnant hot air sequentially opens the through holes 424 formed in the partition 422. The heat generated by the flame emitted from the burner 454 is discharged by the partition 422 by causing the burner 454 to be discharged in the opposite direction to the inner cylinder 420 in which the burner 454 is moved in such a manner as to move between neighboring partitions 422. It gradually moves to the other side, maximizing the thermal efficiency and at the same time supplying a lot of heat to the mixed aggregate is made better mixing.
도 10은 본 발명에 따른 혼합부의 또 다른 실시예를 보인 도면이다.10 is a view showing another embodiment of the mixing unit according to the present invention.
이에 도시된 바와 같이 상기 혼합부(410)의 내통(420)에 설치되어 열을 발산하는 가열부(450)는 내통(420)의 내주면에 부착되는 방식으로 하여 다수개의 발열선(456)이 구비된다.As shown in the drawing, the heating unit 450 installed in the inner cylinder 420 of the mixing unit 410 to dissipate heat is provided with a plurality of heating wires 456 in a manner that is attached to the inner circumferential surface of the inner cylinder 420. .
이와 같이 구성된 본 발명에 따른 중앙식 연속 아스콘 생산장치에 대한 작용관계는 전자에서와 동일한 방법에 의해 이루어지는 것으로, 여기에서는 작용관계에 대한 설명은 생략한다.The working relationship for the central continuous ascon production apparatus according to the present invention configured as described above is made by the same method as in the former, the description of the working relationship is omitted here.
다만, 상기 내통(420)의 내주면에 설치된 다수개의 발열선(456)은 외부로부터 공급되는 전원에 의해 발열이 이루어지고, 이 발열선(456)에서 발산하는 열은 내통(420)으로 전달되어 제1,2호퍼(414)(416)로 투입된 폐골재와 신골재의 교반시 열을 간접적으로 공급하여 열교환이 이루어지게 한다. 그 결과 폐골재와 신골재의 혼합이 잘 이루어지도록 도우며, 급격한 산화노화도 방지할 수 있게 한다.However, the plurality of heating wires 456 installed on the inner circumferential surface of the inner cylinder 420 is generated by the power supplied from the outside, the heat emitted from the heating line 456 is transferred to the inner cylinder 420, the first, When the waste aggregate and new aggregate introduced into the two hoppers 414 and 416 are indirectly supplied with heat, heat is made. As a result, it helps the mixing of waste aggregate and new aggregate well, and also prevents rapid oxidation aging.
이와 같이 구성된 본 발명에 따른 중앙식 연속 아스콘 생산장치의 작용관계는 전자에서와 동일한 방법에 의해 이루어지는 것으로, 여기에서는 작용관계에 대한 설명은 생략한다.The working relationship of the central continuous ascon production apparatus according to the present invention configured as described above is made by the same method as in the former, the description of the working relationship is omitted here.
도 11은 본 발명에 따른 중앙식 연속 아스콘 생산장치의 또 다른 실시예를 보인 도면이다.11 is a view showing another embodiment of the central continuous ascon production apparatus according to the present invention.
이에 도시된 바와 같이 상기 외통(412)의 외주면에는 열을 발산하여 외통(412) 내측에 위치한 재료온도를 더 빨리 상승시킬 목적으로 내통(420) 내측에 가열부재(470)가 구비된다.As shown in the drawing, the outer circumferential surface of the outer cylinder 412 is provided with a heating member 470 inside the inner cylinder 420 for the purpose of dissipating heat to quickly increase the material temperature located inside the outer cylinder 412.

그리고, 상기 외통(412)의 외주면에는 외통(412) 외부의 가열부재(470)와 외통(412) 내부로부터 발산하는 열이 외부로 소실되는 것을 차단하는 단열재(472)가 구비된다.In addition, the outer circumferential surface of the outer cylinder 412 is provided with a heat insulator 472 that blocks the heating member 470 outside the outer cylinder 412 and the heat dissipated from the inside of the outer cylinder 412 to the outside.
또한, 상기 외통(412)의 일측부에 설치되어 폐골재가 투입되는 제1호퍼(414)에는 내통(420)이 회전하는 속도에 맞추어 폐골재가 투입되도록 투입량과 속도를 조절하는 스크루축(474)이 구비되고, 이 스크루축(474)의 상단부에는 스프라켓(476)이 구비되며, 이 스프라켓(476)과 체인(477)에 의해 연결되어 스크루축(476)을 회전시키는 모터(478)가 구비된다.In addition, the screw shaft 474 is installed on one side of the outer cylinder 412 to adjust the input amount and speed so that the waste aggregate is injected into the first hopper 414 to which the waste aggregate is introduced, in accordance with the speed at which the inner cylinder 420 rotates. Sprocket 476 is provided at the upper end of the screw shaft 474, and the motor 478 is connected by the sprocket 476 and the chain 477 to rotate the screw shaft 476. do.
이와 같이 구성된 본 발명에 따른 중앙식 연속 아스콘 생산장치에 대한 작용관계는 전자에서와 동일한 방법에 의해 이루어지는 것으로, 여기에서는 작용관계에 대한 설명은 생략한다.The working relationship for the central continuous ascon production apparatus according to the present invention configured as described above is made by the same method as in the former, the description of the working relationship is omitted here.
다만, 상기 제1호퍼(414)로 폐골재를 투입하기 위한 스크루축(474)의 속도와 내통(420)의 회전속도가 맞지 않을 경우에는 내통(420)의 회전이 방해받거나, 또는 외통(412)의 내측이 막히는 현상이 발생하게 되어 내통(420)의 회전시에 과부하가 발생하여 각 부품, 특히 교반부재(430)가 파손될 염려가 있어 주위할 필요가 있다.다.However, when the speed of the screw shaft 474 for introducing the waste aggregate into the first hopper 414 and the rotation speed of the inner cylinder 420 do not match, the rotation of the inner cylinder 420 is hindered, or the outer cylinder 412. The inside of the c) is clogged, and an overload occurs during the rotation of the inner cylinder 420, which may damage each component, especially the stirring member 430.
따라서, 상기 제1호퍼(414)에 일정한 속도 및 양으로 폐골재를 공급할 수 있도록 제1호퍼(414)에 스크루축(474)을 구비함으로써, 내통(420)의 회전을 방해하지 않고, 항상 일정한 속도로 폐골재가 공급되게 되어 일정한 생산량을 확보할 수 있게 된다.Therefore, by providing a screw shaft 474 in the first hopper 414 to supply the waste aggregate to the first hopper 414 at a constant speed and quantity, it is always constant without disturbing the rotation of the inner cylinder 420.

It is easily done.
도 12는 본 발명에 따른 중앙식 연속 아스콘 생산장치의 또 다른 실시예를 보인 도면이다.12 is a view showing another embodiment of the central continuous ascon production apparatus according to the present invention.
이에 도시된 바와 같이 상기 외통(412)의 일측부, 즉 제1,2,3호퍼(414)(416)(417)가 형성된 타측 길이 방향 끝단부에는 배출구(418)가 형성된다.As shown therein, an outlet 418 is formed at one side portion of the outer cylinder 412, that is, the other longitudinal end portion in which the first, second and third hoppers 414, 416 and 417 are formed.
여기서, 상기 외통(412)의 큰 관 끝단부에는 작은 관이 형성되고, 이 작은 관에는 배출구(418)가 형성되며, 생산된 아스콘은 배출구(418)를 통해 배출된다.Here, a small tube is formed at the end of the large tube of the outer cylinder 412, the outlet 418 is formed in this small tube, the produced ascon is discharged through the outlet 418.
나아가, 상기 내통(420)의 직경도 외통의 직경과 일정한 간격을 두고 작아지되 작아지는 비율은 큰 관부분에서의 재료이송 양이 변함없이 그대로 유지되는 범위 내에서 내통(420)의 작은 관(421)을 형성하며, 작은 관(421) 주변에는 스크루(421a)가 형성되어 있어 내통(420)과 외통(412) 사이에 운반된 재료를 스크루(421a)를 이용하여 배출구(418)로 배출시킨다. Further, the diameter of the inner cylinder 420 is also small at a constant interval with the diameter of the outer cylinder, but the small ratio is small pipe 421 of the inner cylinder 420 within the range that the amount of material transfer in the large pipe portion remains unchanged. And a screw 421a is formed around the small tube 421 to discharge the material conveyed between the inner cylinder 420 and the outer cylinder 412 to the outlet 418 using the screw 421a.
이때, 상기 스크루(421a)는 배출구(418)까지만 형성되며 그 이후에는 스크루 (421a) 없이 작은 관(421)만 연장되어 끝부분에 베어링으로 고정하여 내통(420)의 균형을 유지시킨다.
