이것에 의해, 제 2 건조부(200)에서 건조된 슬러지를 각각의 스크류 이송장치(220, 230)가 각각의 압축부(400)로 공급할 수 있어, 제 2 건조부(200)의 슬러지를 빠른 속도로 각각의 압축부(400)로 공급하고, 제 1 건조부(100)로부터 슬러지를 다시 받아 들일 수 있어, 슬러지를 건조하고 케이크를 성형하는 생산속도를 높일 수 있는 장점이 있다. As a result, the sludge dried in the second drying unit 200 can be supplied to each of the screw conveying devices 220 and 230 to the respective compression units 400, so that the sludge of the second drying unit 200 can be quickly removed. Supplying to each compression unit 400 at a speed, it is possible to accept the sludge again from the first drying unit 100, there is an advantage that can increase the production speed for drying the sludge and molding the cake.

도 1을 다시 참조하면, 상기 압축부(400)는 압축 실린더(402)에 압축 피스톤 (414)이 제 1 공압실린더(410)에 의해 승하강될 수 있도록 장착되고, 상기 압축 실 린더(402)의 하단에 배치되는 받침판(420)에 제 2 공압실린더(425)가 연결되어, 상기 받침판(420)이 제 2 실린더(425)에 의해 화살표(425)와 같이 제 2 공압실린더 쪽으로 이동되어 압축 실린더(402)에서 벗어남으로써, 압축 피스톤(414)에 의해 압축된 슬러지 케이크(450)가 하부에 배치된 압축된 컨베이어(500)로 낙하된다.Referring back to FIG. 1, the compression unit 400 is mounted to the compression cylinder 402 so that the compression piston 414 can be lifted up and down by the first pneumatic cylinder 410, and the compression cylinder 402 The second pneumatic cylinder 425 is connected to the support plate 420 disposed at the bottom of the support plate, and the support plate 420 is moved toward the second pneumatic cylinder by the second cylinder 425 as shown by the arrow 425. By leaving 402, the sludge cake 450 compressed by the compression piston 414 falls onto the compressed conveyor 500 disposed below.

이것에 의해, 제 2 건조부(200)의 스크류 이송장치(220)에 의해 건조된 슬러지가 압축 실린더(402)로 공급되면, 압축 피스톤(414)이 제 1 공압실린더(410)에 의해 압축 실린더(402)로 하강되어, 슬러지를 압축하게 된다. 슬러지의 압축이 완료되면, 제 2 공압실런더(425)에 의해 받침판(420)이 압축 실린더(402)에서 인출됨으로써, 슬러지 케이크(450)가 컨베이어(500)로 낙하되고, 상기 압축 피스톤(414)이 원위치로 상승되고, 받침판(420)이 원위치로 리턴된다. 이와같은 작업을 반복하여 계속해서 슬러지 케이크를 압축성형할 수 있게 된다.As a result, when the sludge dried by the screw feeder 220 of the second drying unit 200 is supplied to the compression cylinder 402, the compression piston 414 is compressed by the first pneumatic cylinder 410. It is lowered to 402 to compress the sludge. When the compression of the sludge is completed, the support plate 420 is drawn out of the compression cylinder 402 by the second pneumatic cylinder 425, so that the sludge cake 450 falls to the conveyor 500, the compression piston 414 ) Is raised to the original position, and the backing plate 420 is returned to the original position. This operation can be repeated to continuously compact the sludge cake.

이와같이, 슬러지를 케이크 형태로 압축하여 부피를 줄임으로써, 차량의 적재효율을 높여 차량이송비를 절감할 수 있고, 매립장에서의 매립효율을 높일 수 있다.In this way, by compressing the sludge in the form of a cake to reduce the volume, it is possible to reduce the vehicle transportation cost by increasing the loading efficiency of the vehicle, it is possible to increase the landfill efficiency at the landfill.
