상기 트롬멜선별기는 다양항 크기의 타공망이 형성된 원통을 경사지게 설치후 회전시키면서 일정 크기 이하의 토사가 하부로 배출되도록 하는 선별 장치이고,The trommel sorter is a sorting device for discharging the soil of a predetermined size or less to the lower side while rotating inclinedly installed cylinder formed with a perforated network of various terms size,
상기 진동 평판 선별기는 메쉬망 또는 타공망이 형성된 평판을 경사지게 설치 후 바이브레이터 등을 이용하여 진동을 주면서 토사를 이동시켜 일정 크기 이하의 토사가 하부로 배출되도록 하는 선별 장치이다.The vibrating plate sorter is a sorting device for discharging the soil of a predetermined size or less to the bottom by moving the soil by vibrating the vibrator or the like after the inclined flat plate formed mesh or perforated network.
상기 디스크 스크린은 다수의 디스크를 1축상에 좌우로 다수 배열하고, 이러한 축을 전후로 다수 배열하여 구성하여, 그 디스크 간의 간격을 배출시키고자 하는 토사의 크기 정도로 배열한 후 축에 구동력을 제공하여 회전시킴으로써 디스크 사이의 간격보다 큰 토사는 이동시키고 그보다 작은 토사는 하부로 배출되도록 하는 선별 장치이다.The disk screen is configured by arranging a plurality of disks left and right on one axis, and arranging a plurality of these axes back and forth, and arranging them to the size of the soil to discharge the gaps between the disks, and then rotating by providing a driving force to the shafts. Soil larger than the gap between the disks moves and the smaller soil is discharged to the bottom.
하지만 상기 트롬멜 선별기 및 진동 선별기는 함수량이 적은 토사 선별시는 효과적이지만, 함수량이 많은 토사를 선별시는 타공망이 막히는 문제점이 있고,However, the trommel sorter and the vibration sorter is effective in sorting soils with low water content, but there is a problem that a perforated network is blocked when sorting soils with high water content,
또한 상기 디스크 선별기는 트롬멜 선별기 및 진동 선별기에 비해 디스크 회전 방식이라 토사의 막힘 현상 등은 많이 개선 되었지만 이 역시 함수량이 많은 토사 선별시는 디스크 사이에 끼는 현상이 많았다. 특히 공급되는 토사가 습지 농지(논) 등에서 발생하는 점토성과 함수율이 높은 토사일 경우 디스크 사이 사이의 간격 차이로 토사를 선별하는 디스크 스크린 특성상 점토성과 함수율이 높은 토사에 의하여 디스크 사이 사이가 막힘이 발생하고, 토사가 뭉쳐져서 공 모양이 되고 선별되지 못하고 배출되는 현상이 발생하고, 토사에 비닐이나 실 같은 이물질이 있을 경우 감김 현상이 발생한다는 구조적 단점이 있다.In addition, the disk sorter is a disk rotation type compared to the trommel sorter and vibration sorter, so the blockage of the earth and sand has been improved a lot, but this also has a lot of phenomenon caught between the disks in the soil-selected soil. Particularly, when the supplied soil is clay having high moisture content and moisture generated in wetland farmland (paddy field), blockage between the disk is caused by clay having high clay and moisture content due to the characteristics of the disk screen that selects soil due to the difference between the disks. And, there is a structural disadvantage that the soil is agglomerated into a ball shape, not being screened and discharged, and when there is a foreign material such as vinyl or thread in the soil, a winding phenomenon occurs.
일반적으로 디스크 스크린에 사용되는 디스크 형상은 원판형, 다각형 등이 주된 형상인데, 이와 달리 디스크의 탄성력을 이용하여 선별율을 높이기 위해 도 9에 나타난 바와 같이 다수개의 고무재질 나선날로 이루어진 별모양으로 구성한 것이 있는데, 이 고무 재질과 형상을 중심부에서부터 나선날이 형성된 디스크는 폭(두께)은 보통 16mm 두께로 제작되어, 1축에 각각 선별 규격(8 ~ 25mm)에 맞는 간격으로 다수의 디스크를 축에 삽입하여 조립한 후 조립된 다수의 디스크 조립체를 전후로 서로 엇갈리게 다수개의 축을 배열하여, 구동력이 전달된 다수의 디스크 축 조립체가 고속 회전하면서 디스크 사이 간격(8 ~ 25mm)보다 적은 크기의 토사는 선별하고, 간격 이상의 크기는 배출하는 선별 장치로 다수의 디스크 축 조립체는 서로 체인으로 연결하여 모터에 의하여 구동된다.In general, the disk shape used in the disk screen is a disk-shaped, polygonal, etc., the main shape, on the other hand to form a star shape consisting of a plurality of rubber material spiral blades as shown in Figure 9 to increase the screening rate by using the elastic force of the disk This rubber material and shape is made of spiral blades from the center of the disk, the width (thickness) is usually made of 16mm thick, and each disk has a plurality of disks on the shaft at intervals that meet the selection standard (8-25mm). After inserting and assembling, the plurality of assembled disk assemblies are arranged in a staggered direction. The plurality of disk shaft assemblies to which the driving force is transmitted are rotated at high speed, and the soils smaller than the distance between the disks (8 to 25 mm) are sorted out. It is a sorting device that discharges more than the gap. Multiple disc shaft assemblies are connected to each other in a chain Is driven.
하지만 상기와 같이 다수의 나선 날개를 가진 별 모양의 디스크 역시 고함수비의 토사 선별시 점토성 토사가 고착되거나 공 모양으로 만들어져 선별 효과가 떨어지는 단점이 있다.However, as described above, the star-shaped disk having a plurality of spiral wings also has a disadvantage in that the sedimentary clay sediment is fixed or made in a ball shape at the time of sediment selection of high water content.
한편, 상기와 같은 구조를 가진 디스크 선별기(스크린)를 이용한 토사 선별 장치는 단독으로 사용시 뭉친 토사가 공급시 디스크 선별 장치 작동에 무리가 있음므로 사전에 이를 적절히 전처리하는 수단이 필요하고, 또한 분급되어 선별된 토사 중 포함된 이물질을 효율적으로 선별하여 정밀한 분급 및 선별이 이루어 질 수 있게 하는 수단의 필요성이 대두되고 있다. On the other hand, the earth and sand sorting device using the disk sorter (screen) having the structure as described above requires a means for appropriately pre-treatment beforehand because it is difficult to operate the disk sorting device when supplying the aggregated soil when used alone There is a need for a means for efficiently classifying and sorting foreign matter contained in selected soils.
또한 디스크 스크린에 장치된 모근 회전축의 속도가 단일한 모터에 의한 단일의 회전력을 제공 받기 때문에 서로 다른 성질(함수율, 점토성)이 복합적으로 섞인 토사가 공급될 경우 일부 성질의 토사는 잘 선별되지만 나머지 성질을 갖는 토사는 잘 선별되지 못한다는 단점이 있어 복합적인 토사 공급시 이를 전체적으로 고르게 선별할 수 있는 수단의 필요성이 대두되고 있다.In addition, because the speed of the root axis of rotation installed in the disk screen is provided with a single rotational force by a single motor, when the soil is mixed with different properties (water content, clay), the soil of some properties is well selected but the rest Soil having a property has a disadvantage that it is not well screened, there is a need for a means that can be evenly selected as a whole when a complex soil supply.

When one unit double disk is installed, a unit space disk, that is, at least one unit double disk, is left, and another unit double disk is installed. To this end, the spacing between neighboring unit dual disks is maintained by using a second spacer 120 for adjusting the dual disk spacing installed on the shaft. That is, the unit double disk 100 and the second spacer 120 for adjusting the dual disk spacing are alternately installed on the shaft.
이중 디스크 간격 조절용 제 2 스페이서(120)가 설치된 축 상의 공간은 일종의 버퍼 공간을 이룰 수 있는데, 이러한 버퍼 공간 때문에 함수비가 높은 토사를 단위 이중 디스크들이 회전시 디스크 사이에 끼거나 뭉쳐졌을 때 회전에 무리를 주지 않고 이러한 공간으로 밀려나게 됨으로써 회전하는 축과 디스크의 부하를 덜어줄 수 있게 된다.The space on the axis on which the dual disk spacing second spacer 120 is installed can form a kind of buffer space. Due to the buffer space, the soil containing high water content is difficult to rotate when the unit double disks are sandwiched or packed together during the rotation. By being pushed into these spaces without relieving, the load on the rotating shaft and disk can be reduced.
본 발명의 이중 디스크 선별기(1)는 상기와 같이 복수개의 단위 이중 디스크(100)가 설치된 축(110)이 토사의 진행 방향 전후로 복수개 설치되는데, 앞뒤 축상에 설치된 단위 이중 디스크는 서로 엇갈리게 설치되어 2개의 축 사이 공간에서 이웃하는 단위 이중 디스크간이 연속적으로 균일한 간극을 유지하게 된다.In the dual disk sorter 1 of the present invention, a plurality of shafts 110 in which the plurality of unit dual disks 100 are installed as described above are installed in front and rear of the earth-moving direction, and the unit dual disks installed on the front and rear shafts are alternately installed. In the space between the two axes, adjacent unit double disks maintain a uniform gap continuously.
또한 축 상에 설치된 단위 이중 디스크의 끝단과 이웃하는 전후 축간의 간극 역시 디스크 간의 간격과 비슷한 간격을 가지게 설치한다. 이와 같이 설치되어야 필요로 하는 토사 선별 크기에 맞는 토사가 하부로 낙하되기 때문이다.In addition, the gap between the end of the unit double disk and the adjacent front and rear axes installed on the shaft is also installed to have a similar gap between the disk. This is because the earth and sand suitable for the size of the earth and sand sorting that needs to be installed in this way falls to the bottom.
상기 단위 이중 디스크(100)는 마치 별 모양과 같은 2개의 디스크(102)가 가운데 위치한 제 1 스페이서에 의해 필요로 하는 간극을 유지토록 하여 일체로 결합되어 단위 이중 디스크를 이룬다. 여기서 결합이라는 것은 축상에 순차적으로 조립하여 하나를 이룬다는 개념이다. 꼭 용접등의 결합이 필요한 것은 아니다.The unit double disk 100 is integrally coupled to form a unit double disk so as to maintain a gap required by a first spacer in which two disks 102 having a star shape are located in the center. Coupling is the concept of forming one by sequential assembly on the axis. It is not necessary to combine welding.
상기 별 모양 디스크(102)라 함은 축(110)과 축 결합되도록 중앙에 천공된 사각홈을 포함한 다각홈이 형성된 디스크의 둘레 부분이 원형을 이루지 않고 복수개의 조각 날개(1021)가 형성되도록 가공한 것으로, 조각 날개의 형상이 전술한 종래 고무재질 디스크처럼 나선형의 긴 날개 형상과 달리 외경부에 비해 하부 즉, 디스크 중심 방향쪽으로 갈수록 폭이 넓은 날개로 형성된 것을 말한다. 이와 같은 형상을 가짐으로써 토석 등에 의한 디스크 손상을 막을 수 있게 된다.The star disk 102 is processed so that the circumferential portion of the disk having a polygonal groove including a square groove drilled in the center to be axially coupled to the shaft 110 does not form a circle, but a plurality of engraving wings 1021 are formed. In other words, the shape of the carving wing is formed as a wing wider toward the lower portion, that is toward the disk center direction than the outer diameter portion, unlike the spiral shape of the spiral like the conventional rubber material disk described above. By having such a shape, it is possible to prevent the disk damage caused by soil, etc.
즉, 도시된 바와 같이 본 발명의 한 실시예에 따른 디스크 조각 날개의 형상은 축 회전 방향쪽 단면은 곡률을 이루는 형상이고 후방부는 수직하게 절단된 형상이다. 마치 원판을 수직선과 수평선으로 1/4로 나눈 하나의 형상이 본 발명 디스키크 둘레에 형성된 하나의 조각 날개 형상과 같다. 도면의 한 실시예에서는 디스크 둘레에 8개 정도 배열하게 도시되어 있다.That is, the shape of the disk piece wing according to an embodiment of the present invention as shown in the axial rotation direction cross section is the shape of the curvature and the rear portion is a vertically cut shape. It is as if the shape of the disk divided into 1/4 by the vertical line and the horizontal line is the shape of one piece wing formed around the present invention. In one embodiment of the figure, eight or so are arranged around the disk.
또한 디스크의 재질은 금속재질로, 바람직하게는 부식이 잘 일어나지 않는 스테인레스 또는 합금 등의 금속 재질로 구성한다.In addition, the material of the disk is made of a metal material, preferably made of a metal material such as stainless or alloy, which is hardly corroded.
디스크의 가운데 형성된 원통형 제 1 스페이서(101)는 상기 2개의 별모양 디스크(102)가 선별코자 하는 토사 크기에 따라 필요로 하는 간극으로 이격되게 그 길이를 절단하고, 제 1 스페이서 양측단에 디스크를 조립(또는 위치)하여 일체화 하면 된다. 이때 필요로 하는 디스크간의 간극이란 본 발명의 한 실시예에 따르면 8mm 정도가 되게 한다. 이는 8mm 이하의 토사를 선별시를 기준으로 한 것으로 그 크기는 선별 크기에 따라 예를 들어 8 ~ 25mm 정도로 다르게 설정하여 제작하면 된다. 즉, 본 발명의 한 실시예에 따른 단위 이중 디스크는 4mm 두께를 가진 2개의 스테인레스 디스크 사이에 8mm의 크기를 가지는 제 1 스페이서를 설치 조립하여 1개의 단위 이중 디스크를 구성하게 된다. 이와 같이 구성된 단위 이중 디스크는 점토성 토사의 고착도 방지되고, 공 모양으로 만들어지는 토사를 파쇄하는 효과가 있게 된다.The cylindrical first spacer 101 formed in the center of the disk is cut in length so that the two star disks 102 are spaced apart by the required gap according to the soil size to be sorted, and the disks are disposed at both ends of the first spacer. What is necessary is to assemble (or position) and to integrate. In this case, the gap between the disks is required to be about 8 mm according to one embodiment of the present invention. This is based on the screening of the soil of less than 8mm, the size is, for example, according to the sorting size may be produced by setting differently about 8 ~ 25mm. That is, the unit double disk according to an embodiment of the present invention is installed by assembling a first spacer having a size of 8mm between two stainless disks having a thickness of 4mm to configure one unit double disk. The unit double disk configured as described above also prevents the seizure of clay soil and prevents the soil from being formed into a ball shape.
또한 2개의 축 상에 설치되어 서로 엇갈리게 배열된 이웃하는 단위 이중 디스크간의 간극 역시 8mm의 간극을 유지하게 설치된다.In addition, the gap between neighboring unit double disks arranged on two axes and staggered with each other is also installed to maintain a gap of 8 mm.
한편, 본 발명은 상기 단위 이중 디스크 사이에 끼는 토사를 물리적으로 제거하기 위해 축(110) 하부에 스크래퍼(130)를 수직하게 설치하였다. 스크래퍼의 설치 개수는 바람직하게 개별 축당 하나씩 설치할 수도 있고, 몇 개의 축 당 하나의 축 하부에만 설치할 수도 있다.On the other hand, in the present invention, the scraper 130 is vertically installed in the lower portion of the shaft 110 to physically remove the soil sandwiched between the unit double disk. The number of scrapers to be installed may be preferably one per individual shaft or may be installed only under one shaft per several shafts.
이와 같은 스크래퍼는 종래의 디스크식 선별기에는 설치하기가 불가능하였다. 그 이유는 종래는 디스크와 동일 크기의 스페이서로만 축 결합체를 구성하였기 때문에 디스크와 디스크 사이 공간에 요철구조의 스크래퍼를 구성할 수 없었기 때문이다. 하지만 본 발명은 크기가 다른 제 1 스페이서와 제 2 스페이서를 사용하여 단위 이중 디스크를 구성시는 제 1 스페이서를 사용하여 토사의 선별 크기를 제어하고, 제 2 스페이서는 단위 이중 디스크 간의 간극만을 유지토록 함으로써 스크래퍼가 설치될 수 있는 공간을 확보했기 때문에 디스크 사이에 꺼거나 디스크 측면에 고착된 토사 제거용 스크래퍼를 설치할 수 있게 되었다. Such a scraper could not be installed in a conventional disc sorter. The reason for this is that conventionally, because the shaft assembly is composed only of spacers having the same size as the disk, a scraper having an uneven structure cannot be formed in the space between the disk and the disk. However, according to the present invention, when the unit double disks are formed by using the first and second spacers of different sizes, the sediment size of the soil is controlled using the first spacers, and the second spacers maintain only the gap between the unit double disks. This ensured a space for the scraper to be installed so that it was possible to install a soil removal scraper that was turned off between the disks or stuck to the side of the disk.
상기 스크래퍼의 구조는 복수개의 홈(131)이 단위 이중 디스크(100)의 간격에 맞게 배열된 요철구조로 이루어져, 단위 이중 디스크(100)가 회전하면서 스크래퍼의 홈(131)에 진입하면 디스크의 외경 둘레부분과 측면 부분의 토사가 제거되게 된다. The scraper structure has a concave-convex structure in which a plurality of grooves 131 are arranged in accordance with the interval of the unit double disk 100, and when the unit double disk 100 rotates and enters the groove 131 of the scraper, the outer diameter of the disk The soil of the circumference and the side part is removed.
이와 같은 구성에 의해 단위 이중 디스크 사이 사이에 토사가 고착되어 막히는 현상을 방지하여 항상 선별 공간을 유지시키게 된다.This configuration prevents sedimentation and blockage between the unit double disks, thereby maintaining the sorting space at all times.
한편, 본 발명의 이중 디스크 선별기는 종래 일반적인 디스크 선별기와 달리 회전 축(110)이 단일 모터의 구동력으로 사용되어 구동 스프로켓에 전달된 회전력이 이웃하는 스프로켓에 체인이나 벨트 등의 동력 전달 수단(도시 생략)에 의해 전달됨으로써 선별기의 회전축이 동시에 회전하는 종래 방식과 달리 권역별(투입부, 중앙부, 배출부)로 회전 속도를 달리 조절함으로써 항시 서로 다른 성질(함수율, 점토성)이 복합적으로 섞인 토사가 공급되어도 뭉쳐진 토사의 파쇄 효과가 높고 선별 효율을 증대시켰다.On the other hand, the dual disk selector of the present invention, unlike the conventional disk selector, the rotating shaft 110 is used as the driving force of a single motor, the rotational force transmitted to the drive sprocket is a power transmission means such as a chain or belt to the neighboring sprocket (not shown) Unlike the conventional method in which the rotating shaft of the sorter rotates at the same time by being transmitted by), soils mixed with different properties (water content, clay) are always mixed by controlling the rotation speed differently according to the area (inlet, center, and outlet). Even when supplied, the crushing effect of the aggregated soil was high and the sorting efficiency was increased.
이를 위해 복수개로 구성된 축을 3개의 권역별로 각각 별도의 권역 모터인 투입부모터(140), 중앙부모터(141) 및 배출부모터(142)를 구비하여 권역을 담당하는 복수개의 스프로켓에만 해당 권역 모터(투입부모터, 중앙부모터 및 배출부모터)의 회전력이 인가되도록 구성함으로써 투입부, 중앙부 및 배출부의 디스크 회전속도를 달리 구성하였다.To this end, a plurality of shafts are provided for each of the three regional zones, each having a separate regional motor, an inlet motor 140, a central motor 141, and an outlet motor 142. The rotational speeds of the input motor, the central motor and the discharge motor are applied so that the rotation speeds of the disks of the input, the central and the discharge parts are different.
상기 권역별 투입부모터, 중앙부모터 및 배출부모터에 의해 회전하는 축은 이중 디스크 선별기의 프레임(150)의 양측에 설치된 베어링(160) 간을 관통하여 설치되고, 축의 양단에는 스프로켓(170)이 설치된다. 또한 권역별로 나뉘어 설치된 축(110) 중에서 적어도 하나의 스프로켓은 구동 스프로켓(171)으로 이루어져 구동모터인 투입부모터(140), 중앙부모터(141) 및 배출부모터(142) 중 어느 하나의 회전력을 인가 받게 구성된다.The shaft rotated by the region-specific inlet motor, the central motor and the outlet motor is installed through the bearings 160 installed on both sides of the frame 150 of the dual disk sorter, and sprockets 170 are installed at both ends of the shaft. do. In addition, at least one sprocket among the shafts 110 divided by districts includes a driving sprocket 171 to rotate the rotational force of any one of an input motor 140, a central motor 141, and an outlet motor 142, which are driving motors. It is configured to be authorized.
이와 같이 구성됨으로써 권역별 담당 구동모터(투입부모터(140), 중앙부모터(141) 및 배출부모터(142) 중의 어느 하나)가 회전하면 구동 스프로켓을 회전시키게 되고, 구동 스프로켓은 이웃하는 스프로켓과 체인이나 벨트 등의 동력 전달 수단(도시 생략)으로 연결된 스크로켓을 연동시켜 회전시키게 된다. 이와 같은 구동모터와 구동 스프로켓 및 스프로켓간의 연결에 의한 동력 전달 방식을 일반적인 동력 전달 방식이므로 추가적인 설명은 생략한다.In this way, when the driving motor (one of the inlet motor 140, the central motor 141, and the outlet motor 142) for each zone rotates, the driving sprocket is rotated, and the driving sprocket is adjacent to the neighboring sprocket. It rotates by interlocking the scrocket connected by a power transmission means (not shown), such as a chain or a belt. Since the power transmission method by the connection between the drive motor and the drive sprocket and the sprocket is a general power transmission method, further description thereof will be omitted.
이하 상기와 같은 이중 디스크 선별기를 구비한 토사 선별 장치를 설명한다.Hereinafter, the earth and sand sorting apparatus including the double disk sorting machine will be described.
도 5는 본 발명의 한 실시예에 따른 이중 디스크 선별기를 구비한 토사 선별 장치를 보인 사시도이고, 도 6은 본 발명의 한 실시예에 따른 이중 디스크 선별기를 구비한 토사 선별 장치를 보인 정면도이고, 도 7은 본 발명의 한 실시예에 따른 이중 디스크 선별기를 구비한 토사 선별 장치를 보인 평면도이고, 도 8은 본 발명의 한 실시예에 따른 이중 디스크 선별기를 구비한 토사 선별 장치를 보인 측면도이다.FIG. 5 is a perspective view illustrating an earth and sand sorting device having a dual disk sorting device according to an embodiment of the present invention, and FIG. 6 is a front view of a soil sorting device having a dual disk sorting device according to an embodiment of the present invention. FIG. 7 is a plan view showing an earth and sand sorting device having a dual disk sorting device according to an embodiment of the present invention, and FIG. 8 is a side view showing a soil sorting device having a dual disk sorting device according to an embodiment of the present invention.
본 발명 토사 선별 장치는 기본적으로 상기한 이중 디스크 선별기(1)를 중심으로 일반적인 토사 선별장치처럼 진동컨베이어, 다수개의 이송용 컨베이어 및 송풍기 등을 구비 하지만 이러한 일반적인 구성 자체가 본 발명의 핵심이 아니고 이중 디스크 선별기의 기술적 사상에 의한 정밀 토사 선별을 위해 유기적으로 결합된 전체 구성이 공지의 타 토사 선별장치와 달리 다양한 크기의 토사 및 골재 그리고 이물질이 혼재된 함수비가 높은 불량 토사까지도 크기별로 정밀 선별 할 수 있다는 것이 본 발명의 핵심 기술적 사상이고 특징이다.The earth and sand sorting device of the present invention basically includes a vibration conveyor, a plurality of conveying conveyors and a blower, like a general earth and sand sorting device, based on the dual disk sorter (1), but this general configuration itself is not the core of the present invention, Unlike other well-known earth soil sorting devices, the whole composition organically combined for precise soil sorting by the technical concept of the disk sorting machine can precisely sort even the poor soils with high water content mixed with various sizes of soils and aggregates. It is a key technical idea and feature of the present invention.
도시된 바와 같이 야적된 다양한 크기의 토사 및 골재 그리고 이물질이 혼재된 함수비가 높은 불량 토사는 진동호퍼(2)로 공급되어 진동에 의해 뭉침 현상이 어느 정도 개선된 후, 진동호퍼의 끝단 하부에 설치된 투입 컨베이어(3)로 낙하된 후 경사면을 따라 이송하여 그 끝단에서 이중 디스크 선별기(1)로 낙하하게 된다. As shown in the figure, soils and aggregates of various sizes, and bad soils having a high water content mixed with foreign matters are supplied to the vibration hopper 2 to improve agglomeration due to vibration, and then installed at the lower end of the vibration hopper. After falling to the input conveyor (3) is transported along the inclined surface to fall to the double disk sorter (1) at its end.
상기 진동호퍼(2)는 끝단에는 막대 모양의 바형 스크린(21)이 설치되어 복수개의 바(211) 간 거리를 조절함으로써 투입 컨베이어(3)로 낙하하는 토사의 크기를 제어할 수 있다. 여기서 바(211)는 필요로 하는 설정 규격에 따라 진동호퍼(2) 본체와 볼트식으로 교환 설치하여 조절할 수 있다.The vibration hopper 2 is provided with a bar-shaped bar-shaped screen 21 at the end to control the size of the soil falling to the input conveyor 3 by adjusting the distance between the plurality of bars 211. Here, the bar 211 can be adjusted by changing the bolt-type body and the vibration hopper 2 according to the required setting standard.
또한 투입 컨베이어(3)로 이송중인 토사의 뭉침을 개선하여 이중 디스크 선별기(1)로 공급시키기 위해 투입 컨베이어(3)의 일 지점 사이드 가이드 상부에 디스크형 토사 파쇄기(4)가 설치된다.In addition, in order to improve the agglomeration of the soil to be conveyed to the input conveyor (3) and to supply to the dual disk sorting machine (1), a disk-type earth and sand crusher (4) is installed on one side side guide top of the input conveyor (3).
상기 디스크형 토사 파쇄기(4)는 모터와 연결된 구동 회전축(41)에 복수개의 브러시 디스크(42)가 축방향으로 설치되고, 복수개의 브러시 디스크(42) 상부는 반원통 형상의 하부가 개방된 메쉬 덮개(43)로 덮어 구성한다. 브러시 디스크(42)는 디스크 주변에 형성된 복수개의 브러시 날개가 이송중인 토사를 깊게 긁도록 함으로써 진동호퍼(2)에서 낙하된 상태로 이송중인 토사가 일정 높이 이상으로 높게 뭉쳐될 경우 이를 파헤쳐 토사의 높이를 넓게 골고루 퍼지게 함과 동시에 내부에 있는 실이나 비닐등의 이물질이 걸리도록 하는 역할을 하게 된다. 또한 메쉬 덮개(43)를 구성한 이유는 이송중인 토사가 높을 경우 메쉬에 의해 부서지도록 하여 디스크형 토사 파쇄기에 가해지는 토사의 부하를 줄이기 위함이다.The disk-type earth and sand crusher 4 has a plurality of brush disks 42 are installed in the axial direction on the drive shaft 41 connected to the motor, the upper portion of the plurality of brush disks 42 is a semi-cylindrical lower opening mesh Covered with a cover 43 is configured. Brush disk 42 has a plurality of brush blades formed around the disk to scrape the soil to be transported deeply by digging the soil in the dropping state from the vibration hopper (2) when the higher than a certain height to dig it up the height of the soil It spreads evenly and at the same time plays a role to catch foreign materials such as thread or vinyl inside. In addition, the reason why the mesh cover 43 is configured is to reduce the load of the earth and sand applied to the disk-type earth and sand crusher when the soil being transported is high by being broken by the mesh.
이중 디스크 선별기(1)로 낙하한 고함수비를 가진 토사는, 토사의 진행방향으로 복수개의 축(110) 상에 선별 크기의 간극을 가지고 설치된 복수개의 단위 이중 디스크(100)의 회전력에 의해 크기별로 선별되어 단위 이중 디스크(100)의 간극 이하 크기는 하부로 낙하하고, 이보다 큰 토석류는 이중 디스크 선별기(1)를 지나가게 된다. 이때 이중 디스크 선별기(1)를 구성하는 복수개의 축(110)들은 권역별로 설치된 투입부모터, 중앙부모터 및 배출부모터의 회전 속도에 의해 서로 다른 속도로 회전하면서 단위 이중 디스크(100)를 회전시켜 토사 선별률을 높임과 동시에 뭉침 현상을 예방하게 된다.The soil having a high water content ratio dropped to the dual disk sorter 1 is sized by the rotational force of the plurality of unit double disks 100 installed with a gap of the sorting size on the plurality of shafts 110 in the advancing direction of the soil. As a result, the gap below the unit double disk 100 falls below the size of the unit, and the larger soils pass through the double disc sorter 1. At this time, the plurality of shafts 110 constituting the dual disk selector 1 rotates the unit dual disk 100 while rotating at different speeds by the rotational speeds of the inlet motor, the center motor, and the outlet motor installed in each zone. It will increase the screening rate of soil and prevent agglomeration.
상기 이중 디스크 선별기(1)의 단위 이중 디스크 간의 사이를 통해 하부 컨베이어(5)로 낙하한 선별코자 하는 양질의 토사는 하부 컨베이어(5)를 따라 수평하게 이송하면서 끝단에서 배출되는데, 배출되기 전에 이물질을 제거하여 보다 양질의 토사를 생산하기 위해 하부 컨베이어의 끝단부 상부에 싸이클론 장치(6)의 흡입노즐(61)을 근접되게 설치하여 미세 이물질을 흡입토록 구성하였다. 흡입된 이물질(비닐, 실 등의 가벼운 미세 이물질)은 싸이클론 장치(6)에서 하향 회전하여 저장한 후, 하부에 설치된 로터리 밸브로 배출시키면 된다. 이때 싸이클론 장치(6)의 흡입 풍력은 후술될 송풍기의 흡입력을 싸이클론 장치(6) 상부와 연결하여 싸이클론 장치 내부에 진공 흡입력을 발생시켜 이용하면 된다.The high quality earth and sand to be dropped to the lower conveyor 5 through between the unit double disks of the double disk sorter 1 is discharged from the end while being transported horizontally along the lower conveyor 5, before being discharged. In order to produce a better quality earth and sand, the suction nozzle 61 of the cyclone apparatus 6 was installed close to the upper end of the lower conveyor, so that fine foreign substances were sucked. The sucked foreign matter (light fine foreign matter such as vinyl, seal, etc.) may be rotated and stored in the cyclone apparatus 6 and then discharged by a rotary valve installed at the lower portion. At this time, the suction wind power of the cyclone apparatus 6 may be used by generating a vacuum suction force inside the cyclone apparatus by connecting the suction force of the blower to be described later with the upper portion of the cyclone apparatus 6.
상기 이중 디스크 선별기(1)를 통과한 하부 배출 토사보다 큰 토석류는 이중 디스크 선별기(1)의 끝단에서 낙하한 후 상승컨베이어(7)를 따라 이송 후 끝단에서 낙하후 배출컨베이어(8)를 따라 배출되어 야적되게 된다.Dirts larger than the lower discharged sediment passed through the double disc sorter 1 drop at the end of the double disc sorter 1 and then transported along the ascending conveyor 7 and then discharged along the discharge conveyor 8 after the drop at the end. It becomes wild.
이때 낙하하는 토석류 중의 이물질을 제거하기 위해 상승컨베이어(7)의 끝단에 하부쪽에 송풍기(9)의 송풍노즐(91)을 위치시켜 풍력에 의해 이물질을 날려 상승컨베이어(7)의 건너편에 있는 에어컨베이어(10)로 배출시켜 분리하게 된다. 여기서 에어컨베이어란 컨베이어의 측면 및 상면이 막힌 통로 구조의 막과 그 하부의 컨베이어로 구성된 컨베이어로, 막을 통해 하부 컨베이어로 낙하하지 않고 비산되는 이물질이 대기중으로 비산되어 대기가 오염되는 것을 막도록 구성된다. 이러한 에어컨베이어는 본 출원인의 여러 특허에 개시된 공지의 에어컨베이어 개념이다.At this time, in order to remove the foreign matter in the falling soil, the air blowing nozzle 91 of the blower 9 is positioned at the lower end of the ascending conveyor 7 to blow up the foreign matter by the wind to blow the foreign matter to the air conditioner conveyor across the rising conveyor 7. It is discharged to (10) and separated. Here, the air conditioner conveyor is a conveyor composed of a membrane having a passage structure with the side and top of the conveyor blocked and a conveyor at the bottom thereof, and is configured to prevent foreign substances from being scattered into the atmosphere without falling into the lower conveyor through the membrane to contaminate the atmosphere. . Such an air conditioner is a known air conditioner concept disclosed in the applicant's various patents.
상기 송풍력을 제공하는 송풍기(9)의 흡입구에 형성된 흡입력은 상기 싸이클론 장치(6) 상부와 공기 덕트(92)로 연결되어 제공함으로써 싸이클론 장치 내부에 진공 흡입력을 발생시키게 연결 구성된다.The suction force formed at the suction port of the blower 9 which provides the blowing force is connected to the cyclone apparatus 6 and the air duct 92 so as to generate a vacuum suction force inside the cyclone apparatus.
이하 본 발명의 바람직한 실시예이다.Hereinafter is a preferred embodiment of the present invention.
(실시예1)Example 1
중장비에 의하여 불량 토사가 투입되면 정량 투입장치인 경사각 조절식 진동 호퍼(2)에 의하여 순차적으로 투입되면서 진동 호퍼 끝단의 바형 스크린(211)에 의하여 한 실시예에 따른 설정규격(100mm) 이상은 외부로 낙하시켜서 배출시키고, 설정규격(100)mm 이하는 선별되어 투입컨베이어(3) 및 디스크형 토사 파쇄기(4)를 통하여 뭉친 토사의 높이를 고루게 퍼트린 후 이중 디스크 선별기(1)에 투입한다. 이중 디스크 선별기(1)에서는 단위 이중 디스크의 간극 조정에 의해 설정 규격(8mm) 이하는 하부 컨베이어(5)로 낙하시키고 그 이상은 배출시킨다. 이때 사용되는 이중 디스크 선별기(1)는 습지 농지(논) 등에서 발생하는 점토성과 함수율이 높은 토사도 무리없이 선별하게 된다. 또한 단위 디스크 사이에 끼는 토사는 축 하부에 설치된 스크래퍼를 통해 제거하면서 선별하여 더욱더 선별 효율을 높이게 된다.When the poor soil is injected by heavy equipment, it is sequentially inputted by the inclined angle adjustable vibration hopper (2), which is a fixed quantity input device, and the set standard (100 mm) or more according to an embodiment is determined by the bar-shaped screen 211 at the end of the vibration hopper. And then discharge it, and the set standard (100) mm or less is sorted and spread evenly spread the agglomerated soil level through the input conveyor (3) and the disk-type earth and sand crusher (4), and then put it into the double disk selector (1). . In the double disc sorter 1, below the set size (8 mm) falls to the lower conveyor 5 by adjusting the clearance of a unit double disc, and discharges more.
