Description
본 발명은 전로의 폐열을 이용한 벨트컨베이어의 클리닝장치, 보다 상세하게는 전로에서 사용되는 냉각제와 매용제 등의 부원료를 수송하는 벨트컨베이어에 있어서 이의 하부에서 지지되는 리턴롤러에 습기로 인하여 분진이 부착되는 현상을 방지함으로써 분진이 부착된 리턴롤러가 벨트에 접촉됨으로 인한 벨트 및 리턴롤러의 손상을 줄일 수 있게한 전로의 폐열을 이용한 벨트컨베이어의 클리닝장치에 관한 것이다.The present invention is a cleaning device for a belt conveyor using the waste heat of the converter, more specifically in the belt conveyor for transporting the subsidiary materials such as coolants and solvents used in the converter in which dust is attached to the return roller supported by the lower portion due to moisture. The present invention relates to a cleaning device for a belt conveyor using waste heat of a converter which prevents the phenomenon and reduces the damage of the belt and the return roller due to the contact with the belt.
일반적으로, 전로에서 취련작업을 할 때 사용하는 부원료로 냉각제와 매용제 등이 있으며, 이러한 부원료의 수송은 도 1의 전로의 부원료 공급장치에 대한 개요도에 나타난 바와 같이, 작업자가 통제실의 컴퓨터 모니터(M)를 이용하여 전로(1)에 사용할 부원료의 레벨을 확인한 후 입력장치를 통하여 수송할 부원료의 종류를입력하고, 입력신호에 의해 PLC(programable logic controller ; 2)에서 부원료의 수송을 명령하게 되면 지상호퍼(3)에서 수송된 부원료가 벨트컨베이어(4)(5)(6)를 통하여 이송되어 트리퍼카(7)의 동작으로 각각의 노상호퍼(8)에 공급하게 된다.In general, there are subsidiary materials used for the work in the converter, such as a coolant and a solvent, and the transportation of such subsidiary materials is carried out by the operator of the computer monitor (M) of the control room, as shown in the schematic diagram of the subsidiary material supply of the converter of FIG. After confirming the level of sub-materials to be used for converter (1), input the sub-materials to be transported through the input device, and when the sub-materials are commanded by PLC (programmable logic controller; 2) by the input signal, The subsidiary materials transported from the hopper 3 are conveyed through the belt conveyors 4, 5 and 6 to be supplied to each hearth hopper 8 by the operation of the tripper car 7.
상기와 같이 수송된 부원료는 취련작업중 평량호퍼(9)에 필요한 만큼의 부원료를 평량시킨 후 전로(1)에 투입되며, 이때 부원료의 종류 중에는 생석회, 경소돌로마이트 및 단광 등과 같이 가공상태로 수송하는 것과 자연에서 채취된 그대로를 사용하는 생돌로마이트, 형석 및 철광석 등이 있다.Subsidiary materials transported as described above are added to the converter 1 after weighing as many sub-materials as necessary for the basis weight hopper 9 during the drilling operation. Fresh dolomite, fluorspar and iron ore using natural extracts.
상기 각종 부원료에는 다량의 분진이 함유되어 있고, 자연에서 채취된 것은 야적장에 야적한 상태에서 필요할 때마다 덤프를 이용하여 수송하기 때문에 비가 오게 될 경우 습기를 함유한 채 수송되어 진다.The various subsidiary materials contain a large amount of dust, and because it is transported using a dump whenever it is necessary in the state unloaded in the yard when it rains, it is transported with moisture.
다수의 벨트컨베이어로 구성된 벨트라인을 통하여 부원료가 수송되는 경우에 도 2에서와 같이, 풀리(10)에 의해 궤도운동을 하는 벨트(11)의 외측면에 고무재의 스크레이퍼(12)를 밀착시켜 분진이나 오물을 제거하였으며, 제거된 분진은 백필터라인을 이용하여 집진되고 오물은 하부의 호퍼라인을 통하여 회수된다.When the sub-materials are transported through a belt line composed of a plurality of belt conveyors, as shown in FIG. 2, the rubber scraper 12 is brought into close contact with the outer surface of the belt 11 orbiting by the pulley 10 to be dusted. Or dirt is removed, the removed dust is collected by the bag filter line and the dirt is recovered through the hopper line at the bottom.
그러나 상기와 같이 고무재로 된 스크레이퍼를 사용하는 경우에는 벨트와의 마찰에 의해 스크레이퍼가 빈번하게 마모됨으로써, 원하는 바의 크리닝작업을 하기 위해서는 크리닝장치로부터 고정나사를 풀어 스크레이퍼를 교환해야 되었으므로 작업자에게 많은 불편과 업무부하를 가중시키는 문제점이 있었다.However, in the case of using a rubber scraper as described above, the scraper is frequently worn by friction with the belt. Therefore, in order to perform the desired cleaning work, it was necessary to remove the fixing screw from the cleaning device and replace the scraper. There was a problem that increased the inconvenience and the work load.
또한 상기와 같이 크리닝 작업을 할 때 고무재로 된 스크레이퍼는 벨트에 부착된 분진과 오물만 제거할 뿐, 부원료를 이송하는 과정에 부원료에서 침출되어 벨트에 잔류된 습기는 제거가 거의 불가능 하였다.In addition, when cleaning as described above, the scraper made of rubber material only removes dust and dirt attached to the belt, and it was almost impossible to remove moisture remaining on the belt due to leaching from the subsidiary materials during the process of transferring the subsidiary materials.
특히, 도 3a 내지 3c에서와 같이 높은 위치에서 궤도운동을 하면서 노상호퍼(8)에 부원료를 수송하는 벨트컨베이어(6)의 벨트(11)에는 트리퍼카(7)의 동작에 의해 부원료가 낙하될 때 다량의 분진이 비산됨으로써, 이때 발생하는 분진이 부원료의 수송과정에서 이미 리턴롤러(13)에 붙어 있는 습기에 달라 붙으면서 마치 덩어리(M) 형태로 굳어지게 되었고, 이러한 덩어리 형태로 굳어진 소위 고착분진은 벨트와 접촉되면서 벨트를 조기에 마모시키는 원인이 되었음은 물론 고착분진에 의해 리턴롤러를 자주 교환해야 됨으로써 생산원가를 상승시키는 등의 비경제적인 문제점이 있었다.In particular, in the belt 11 of the belt conveyor 6 for transporting the subsidiary materials to the hearth hopper 8 while orbiting at a high position as shown in FIGS. 3A to 3C, the subsidiary materials are dropped by the operation of the tripper car 7. When a large amount of dust is scattered, the dust generated at this time is solidified in the form of lumps (M) as it adheres to the moisture already attached to the return roller (13) in the transportation process of the sub-materials, so-called fixation The dust was in contact with the belt, causing the belt to wear out prematurely, and the return rollers were frequently replaced by the fixed dust, thereby increasing the production cost.
본 발명은 상기와 같은 종래의 벨트컨베이어의 문제점을 해결하기 위하여 안출된 것으로, 그 목적은 부원료의 수송과정중 침출된 습기가 벨트에 잔류되지 않도록 제거하여 리턴롤러를 청결하게 할 수 있는 전로의 폐열을 이용한 벨트컨베이어의 클리닝장치를 제공하는 것이다.The present invention has been made in order to solve the problems of the conventional belt conveyor as described above, the purpose is to remove the moisture leaching during the transport process of the sub-materials to remove the residual heat of the converter to clean the return roller It is to provide a cleaning device of the belt conveyor using.
이러한 목적을 달성하기 위한 본 발명은 습기가 함유된 부원료를 수송할 때 발생하는 오염물질을 제거하기 위하여 설치한 오염물질제거부와, 분진이 함유된 부원료를 수송할 때 발생하는 벨트에 붙은 먼지를 제거하기 위하여 설치한 분진제거부와, 습기가 함유된 원료 수송시 벨트의 습기를 제거하기 위하여 설치한 습기제거부로 구성함으로써, 벨트의 습기제거로 리턴롤러에 분진이 부착됨을 방지하여 벨트 크리너의 교환시기를 연장하고, 벨트와 리턴롤러와의 접촉에 의한 벨트의 마모 및리턴롤러의 조기교체를 방지함을 특징으로 한다.The present invention for achieving this purpose is to remove the contaminant removal unit installed to remove the contaminants generated when transporting the subsidiary material containing moisture, and dust attached to the belt generated when transporting the subsidiary material containing dust. It consists of a dust removal part installed to remove and a moisture removal part installed to remove moisture from the belt when transporting moisture-containing material, and prevents dust from adhering to the return roller by removing moisture from the belt. It is characterized by prolonging the replacement time and preventing wear of the belt and premature replacement of the return roller by the contact between the belt and the return roller.

상기 클리너를 통과하여 오물이 제거된 벨트(11)가 더욱 진행되어 그 진행동작에 의해 공회전되는 분진제거롤(40)을 통과할 때 이 분진제거롤을 회전 가능하게 지지하는 회전축관(42)을 통해 그 중공부에 장착된 에어노즐(43)과 다공체(41)를 통해 공기를 분사하여 오물이 제거된 벨트(11)에 잔류된 분진을 제거하게 된다.The rotary shaft pipe 42 rotatably supporting the dust removal roll when passing through the cleaner 11 is further passed through the dust removal roll 40, which is idle by the advancing operation. Air is injected through the air nozzle 43 and the porous body 41 mounted through the hollow portion 41 to remove dust remaining on the belt 11 from which dirt is removed.
이어서, 분진이 제거된 벨트(11)가 풀리(10)를 경유하여 리턴되는 과정에서 다수의 분사롤(50)과 제습롤(60)을 통과할 때 분사롤(50)에 형성된 다공체(51)를 통해 폐열회수라인으로부터 회전축관(52)과 노즐(53)을 경유하여 공급된 열풍이 벨트(11)에 가해짐과 동시에 제습롤(60)에 의한 브러싱작용이 이루어짐으로써, 벨트에 묻어있는 물기 또는 습가가 제거되어 청결한 상태의 벨트가 리턴롤러를 통과하게 되는 것이다.Subsequently, the porous body 51 formed on the spray roll 50 when the belt 11 from which dust is removed passes through the plurality of spray rolls 50 and the dehumidification roll 60 in the process of being returned via the pulley 10. Hot air supplied from the waste heat recovery line via the rotary shaft pipe 52 and the nozzle 53 is applied to the belt 11 and the brushing action by the dehumidification roll 60 is performed, thereby causing moisture to be attached to the belt. Alternatively, the humidity is removed and a clean belt passes through the return roller.
상기 오물의 제거와 분진 및 습기의 제거동작은 궤도운동을 하는 벨트가 리턴되는 과정에서 순차적으로 이루어지게 됨으로써 보다 신속하고 간단하게 동작을 완료하게 된다.The removal of dust and the removal of dust and moisture are performed sequentially in the process of returning the orbiting belt to complete the operation more quickly and simply.
따라서, 상기와 같은 본 발명의 전로의 폐열을 이용한 벨트컨베이어의 클리닝장치에 의하면, 제강공정의 노상호퍼의 상부에 습기와 분진를 함유한 부원료를수송하는 과정에 부원료의 특성에 따라 각기 다른 형태로 벨트에 잔류된 이물질을 최적상태에서 제거함으로써 청결도의 향상으로 리턴롤러에 분진이 고작되는 현상을 방지하여 벨트의 손상을 방지할 수 있는 효과가 있다.Therefore, according to the cleaning apparatus of the belt conveyor using the waste heat of the converter of the present invention as described above, in the process of transporting the sub-material containing moisture and dust in the upper part of the hearth hopper of the steelmaking process, the belt in different forms according to the characteristics of the sub-material By removing the foreign matter remaining in the optimum state, it is possible to prevent the damage of the belt by preventing the phenomenon of dust on the return roller by improving the cleanliness.
또한, 리턴롤러에 분진이 고착되는 현상을 방지함으로써 리턴롤러와 벨트의 사용수명을 증대시킴과 아울러 보수유지로 인한 시간을 절약하여 원가절감을 실현할 수 있는 장점도 있다.In addition, by preventing dust from adhering to the return roller, the service life of the return roller and the belt can be increased, and cost reduction can be realized by saving time due to maintenance.
