본 발명은 로터리 킬른 로에 관한 것으로서, 좀 더 상세하게는 다양한 제품의 소성이 가능하면서 소성 과정에서 변형을 방지하고 연속적 공정을 수행하여 생산성을 향상하는 로터리 킬른 로에 관한 것이다.The present invention relates to a rotary kiln furnace, and more particularly, to a rotary kiln furnace capable of firing various products while preventing deformation in the firing process and performing a continuous process to improve productivity.

일반적으로 로터리 킬른은 제철소, 시멘트 제조공장, 쓰레기소각장과 같은 대규모 시설은 물론 도자기 제품이나 분말 소재를 소규모로 소성하기 위한 전기로의 대체 용도로 널리 활용되고 있다.In general, rotary kilns are widely used as an alternative to electric furnaces for small-scale firing of ceramic products or powder materials, as well as large-scale facilities such as steel mills, cement manufacturing plants, and waste incinerators.

도 1은 종래의 일예에 따른 킬른 로를 나타내는 도식도, 도 2는 도 1의 요부를 확대하여 나타내는 도식도이다.1 is a schematic diagram illustrating a kiln furnace according to a conventional example, and FIG. 2 is an enlarged schematic diagram illustrating main parts of FIG. 1.

도 1에서 종래의 킬른 로는 회전통(10)의 내면에 내화벽돌(12)을 일정한 두께로 설치하고, 외면에 치형과 같은 구동기(16)를 설치하며, 회전통(10)의 일측에는 버너(15)를 설치한 구성을 지닌다. 도 2처럼 내화벽돌(12)의 일부는 돌출편(13)으로 형성하여 대상제품의 이송 기능을 겸하기도 한다.In FIG. 1, a conventional kiln furnace has a refractory brick 12 installed at a predetermined thickness on an inner surface of a rotating cylinder 10, and a driver 16 such as a tooth type is installed on an outer surface thereof, and a burner (1) is provided at one side of the rotating cylinder 10. 15) has the configuration installed. As shown in FIG. 2, a part of the refractory brick 12 is formed as a protrusion 13 to serve as a transfer function of the target product.

그러나 이와 같은 방식에 의하면 소성과정에서 발생하는 분진이나 유독가스 등의 유해물질이 대상제품과 직접 접촉할 뿐 아니라 버너(15)에 의한 온도 편차가 발생하면 대상제품에 즉시 영향을 끼치므로 제품의 변형, 변질, 품질의 불균일성 등의 불량을 초래한다.However, according to this method, not only the harmful substances such as dust or toxic gas generated during the firing process come into direct contact with the target product, but also when the temperature deviation by the burner 15 occurs, the target product is immediately affected. It results in poor quality, deterioration and non-uniformity of quality.

또한, 회전통(10)의 내면에 적층 상태로 설치된 내화벽돌(12)이 반복하중의 작용으로 파손과 이탈이 쉬어 내구성을 저하시키는 요인이 된다. 내화벽돌(12)의 돌출편(13)은 믹싱 역할이 강하고 배출 기능이 약하므로 연속적인 소성 공정을 수행할 수 없는 폐단이 있다.In addition, the refractory brick 12 installed in the laminated state on the inner surface of the rotary cylinder 10 is a factor of reducing durability due to easy breakage and detachment due to the action of repeated loads. Since the protrusion 13 of the firebrick 12 has a strong mixing role and a weak discharge function, there is a closed end where a continuous firing process cannot be performed.

이에 따라 본 발명은 상기한 폐단을 해결하기 위한 것으로서, 다양한 제품의 소성이 가능하면서 소성 과정에서 유해물과 접촉에 의한 변형을 방지하고 연속적인 장입과 장출을 수행하여 생산성을 향상하는 로터리 킬른 로를 제공하는 것을 그 목적으로 한다.Accordingly, the present invention is to solve the above-described waste, it is possible to bake a variety of products while preventing the deformation caused by contact with harmful substances during the firing process provides a rotary kiln furnace to improve productivity by performing continuous charging and charging It is for that purpose.

이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명의 일예에 따른 킬른 로를 나타내는 도식도, 도 4는 도 3의 중앙을 종단하여 나타내는 도식도, 도 5는 도 3의 회전지지부를 종단하여 나타내는 도식도이다.Figure 3 is a schematic diagram showing a kiln furnace according to an embodiment of the present invention, Figure 4 is a schematic diagram showing the termination of the center of Figure 3, Figure 5 is a schematic diagram showing the termination of the rotation support of Figure 3.

본 발명은 대상물을 소성, 소각, 건조 가능한 로터리 킬른 로에 관련되는 것으로서, 특히 회전통(30)에서 내화벽돌을 분리하여 유해 가스가 회전통(30)에 침투하지 않도록 한다. 즉 소성, 소각, 건조의 대상물이 회전통(30)을 이동하면서 하우징(20) 내의 열에너지에 의해 간접적으로 가열되는 방식을 요지로 한다.The present invention relates to a rotary kiln furnace that can burn, incinerate, and dry an object. In particular, the refractory brick is separated from the rotary cylinder 30 to prevent harmful gas from penetrating the rotary cylinder 30. That is, the main point of the method is that the object of firing, incineration and drying is heated indirectly by the heat energy in the housing 20 while moving the rotary cylinder 30.

본 발명에 따른 하우징(20)은 내화벽돌로 밀폐되고 상측의 덮개(25)로 개폐 가능한 구조이다. 하우징(20)의 상면은 개방하고 4면을 내화벽돌로 구성하면서 적어도 2개의 내측면에 스트립히터(28)를 일정한 간격으로 설치한다. 하우징(20)의 소재와 스트립히터(28)의 용량은 내부 온도 1450℃를 기준으로 선정한다. 개방된 상면에는 세라믹 울 소재로 형성된 덮개(25)를 설치하여 필요에 따라 하우징(20) 내부로 접근이 가능하도록 한다. 하우징(20)의 저면에는 냉각과 진동 완화를 위한 별도의 지지프레임(22)을 둘 수도 있다.Housing 20 according to the present invention is a structure that is sealed with a refractory brick and can be opened and closed by an upper cover 25. The upper surface of the housing 20 is opened and four surfaces are formed of firebrick, and the strip heaters 28 are installed on at least two inner surfaces at regular intervals. The material of the housing 20 and the capacity of the strip heater 28 are selected based on an internal temperature of 1450 ° C. An open upper surface is provided with a cover 25 formed of a ceramic wool material to allow access to the inside of the housing 20 as necessary. The bottom of the housing 20 may have a separate support frame 22 for cooling and vibration dampening.

또, 본 발명에 따르면 내면에 대상물을 이송하는 대경스크류(35)를 구비하는 회전통(30)이 상기 하우징(20)에 양단이 노출된 상태로 회전가능하게 장착된다. 회전통(30)은 중공의 관구조이며 후술하는 회전지지부(40)에 의해 지지된다. 본 발명 에서 회전통(30)의 내부에 내화벽돌이 구비되지 않으므로 동력손실을 방지하고 내구성을 향상하는 측면에서 유리하다. 회전통(30)의 구동을 위해 외면에 치형을 형성하고 체인이나 기어를 개재하여 모터(36)에 연결한다. 이러한 회전통(30)의 회전수는 3∼20rmp의 저속 범위로 유지된다.In addition, according to the present invention, a rotating cylinder 30 having a large diameter screw 35 for transferring an object to an inner surface thereof is rotatably mounted with both ends exposed to the housing 20. The rotary cylinder 30 is a hollow tubular structure and is supported by the rotary support 40 described later. In the present invention, since the refractory brick is not provided inside the rotating cylinder 30, it is advantageous in terms of preventing power loss and improving durability. To form the teeth on the outer surface for driving the rotary cylinder 30 and is connected to the motor 36 via a chain or gear. The rotation speed of this rotating cylinder 30 is maintained in the low speed range of 3-20 rmp.

이때, 도 4에서 대경스크류(35)는 회전통(30)의 내면에서 일정한 높이로 돌출되어 나선 형태로 이어진다.At this time, the large diameter screw 35 in Figure 4 protrudes to a constant height from the inner surface of the rotating cylinder 30 leads to a spiral form.

또, 본 발명에 따르면 상기 회전통(30)의 양단과 중앙에서 회전 가능하게 지지하도록 회전지지부(40)가 지지대(44)와 함께 설치된다. 지지대(44)는 직육면체의 상면에 반원형의 곡면을 지니는 구조이며 고강도의 캐스터블(castable)을 사용하여 형성된다. 회전지지부(40)의 또 다른 요체로서 지지대(44) 외에 회전 가능한 롤러를 적어도 3점 지지 구조로 배치한다. 2개의 롤러는 회전통(30)의 외측단을 지지하고 1개의 롤러는 중앙부를 지지한다.In addition, according to the present invention, the rotatable support 40 is installed together with the support 44 so as to be rotatably supported at both ends and the center of the rotatable cylinder 30. Support 44 is a structure having a semi-circular curved surface on the upper surface of the rectangular parallelepiped and is formed by using a castable of high strength. As another element of the rotation support portion 40, in addition to the support 44, a rotatable roller is arranged in at least a three-point support structure. Two rollers support the outer end of the rotating cylinder 30, and one roller supports the center part.

또, 본 발명에 따르면 상기 회전지지부(40)가 과열되지 않도록 적어도 일부에 냉각수단이 설치된다. 회전지지부(40) 중에서 하우징(20) 내부에 설치되는 적어도 하나의 롤러는 금속제로서 전술한 지지대(44)와 달리 내열성이 높지 않으므로 냉각수단을 요한다.In addition, according to the present invention, a cooling means is installed at least in part so that the rotation support part 40 is not overheated. At least one roller installed inside the housing 20 of the rotation support part 40 is made of metal, and unlike the support member 44 described above, heat resistance is not high, so cooling means are required.

이때, 본 발명에 따르면 상기 회전통(30)은 대상물을 일정하게 이송하도록 상류단의 장입호퍼(50) 및 소경스크류(55)와, 하류단의 장출구(32)를 더 구비하는 것이 좋다. 장입호퍼(50)의 하단 송출구에서 회전통(30)의 대경스크류(35) 상류단까지 소경스크류(55)가 설치된다. 소경스크류(55)는 지지프레임(52) 상에 지지하며 외단에 모터(56)를 연결한다. 회전통(30)의 하류단에 형성되는 장출구(32)는 경사진 면에 다수의 인출 구멍을 형성한 구조이다.In this case, according to the present invention, the rotary cylinder 30 may further include an upstream end charging hopper 50 and a small diameter screw 55 and a downstream end opening 32 so as to constantly transport the object. The small diameter screw 55 is installed from the lower end outlet of the charging hopper 50 to the upstream end of the large diameter screw 35 of the rotary cylinder 30. The small diameter screw 55 is supported on the support frame 52 and connects the motor 56 to the outer end. The elongate outlet 32 formed in the downstream end of the rotating cylinder 30 is a structure which formed the several drawing hole in the inclined surface.

본 발명의 냉각수단은 로터리조인트(48)를 개재하여 중공 구조의 회전 가능한 수냉롤러(42)와 외부로 인출되는 냉각관(46)을 연결한다. 도 5에서 수냉롤러(42)의 내부에 냉각수의 유로가 형성되고, 외부의 냉각관(46)과 로터리조인트(48)를 통하여 연결된다. 이에 따라 수냉롤러(42)의 내부에 냉각수가 순환되므로 하우징(20) 내부의 고열 환경에서 무리없이 지지기능을 수행할 수 있다.The cooling means of the present invention connects the rotatable water-cooling roller 42 having a hollow structure with the cooling pipe 46 drawn out through the rotary joint 48. In FIG. 5, a flow path of cooling water is formed in the water cooling roller 42, and is connected to an external cooling pipe 46 and a rotary joint 48. Accordingly, since the coolant is circulated in the water cooling roller 42, the support function can be performed without difficulty in a high temperature environment inside the housing 20.

도 6은 본 발명의 다른 예에 따른 킬른 로를 나타내는 도식도이다.6 is a schematic diagram showing a kiln furnace according to another embodiment of the present invention.

본 발명에 따르면 상기 회전통(30)은 상류단의 내면에 형성되는 도입부(30a) 또는 외면에 형성되는 플랜지(38) 중 적어도 하나를 더 구비한다. 도 6에서 도입부(30a)는 소경스크류(55)나 대경스크류(35)가 없는 공간으로 형성한다. 이는 알루미나, Si, 질석, 장석 등의 광물질 분말(3∼600 메쉬)을 소성하기 위한 용도로서 회전통(30)이 서서히 회전함에 따라 자유낙하를 반복하며 대경스크류(35)에 도달하고 하류측으로 이송이 진행된다. 물론 저온에서 커피프림, 참깨 등을 볶을 때에도 이와 같은 구성이 적합하다.According to the present invention, the rotary cylinder 30 further includes at least one of an introduction portion 30a formed on the inner surface of the upstream end or a flange 38 formed on the outer surface. In FIG. 6, the introduction portion 30a is formed as a space without the small diameter screw 55 or the large diameter screw 35. This is for firing mineral powders (3 to 600 mesh) such as alumina, Si, vermiculite, feldspar, etc .. As the rotating cylinder 30 rotates slowly, the free fall is repeated and the large diameter screw 35 is reached and transferred to the downstream side. This is going on. Of course, this configuration is also suitable for roasting coffee cream and sesame seeds at low temperatures.

회전통(30)의 외면에 플랜지(38)를 두는 것은 회전지지부(40)의 하나인 롤러의 측면을 긴밀하게 지지하기 위한 용도로서 회전통(30)을 기울인 상태로 가동하는 구성(미도시)에 있어서 보다 적절하게 적용된다. 회전통(30)의 회전중심이 하류단으로 갈수록 낮아지는 경사구조로 설치하면 대상물의 이송이 보다 원활해지므로 양산에 따른 생산성 향상에 유리하다. 경사 각도가 커지면 장치가 복잡화되고 내구성 이 저하되므로 1∼5°의 범위로 하는 것이 적절하다.Placing the flange 38 on the outer surface of the rotating cylinder 30 is for the purpose of closely supporting the side surface of the roller, which is one of the rotating support 40, the configuration for operating the rotating cylinder 30 in an inclined state (not shown) It is applied more appropriately in. If the center of rotation of the rotary cylinder 30 is installed in an inclined structure lowered toward the downstream end, the transfer of the object becomes smoother, which is advantageous for productivity improvement according to mass production. The larger the inclination angle, the more complicated the device and the lower the durability, so it is appropriate to set it in the range of 1 to 5 °.

이와 같이 본 발명의 로터리 킬른 로는 하우징(20)이 가열되고 회전통(30)에서 대상물이 이동하므로 간접 가열이 구현된다. 하우징(20)의 내부 온도가 다소 변동되어도 그 영향이 회전통(30)의 내부에 즉시 미치지 않으므로 품질을 균일하게 유지할 수 있다.In this way, the rotary kiln furnace of the present invention is the housing 20 is heated and indirect heating is implemented because the object moves in the rotary cylinder (30). Even if the internal temperature of the housing 20 fluctuates somewhat, the influence does not immediately reach the inside of the rotating cylinder 30, so that the quality can be maintained uniformly.

본 발명은 기재된 실시예에 한정되는 것은 아니고, 본 발명의 사상 및 범위를 벗어나지 않고 다양하게 수정 및 변형할 수 있음은 이 기술의 분야에서 통상의 지식을 가진 자에게 자명하다. 따라서 그러한 변형예 또는 수정예들은 본 발명의 특허청구범위에 속한다 해야 할 것이다.It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
