펠트타입의 슬러지 탈수장치{felt type sludge dewatering system}Felt type sludge dewatering system

본 발명은 공장의 폐수에 혼합된 슬러지를 연속적으로 탈수하기 위한 슬러지탈수장치에 관한 것으로 보다 상세하게는 폐수속에 함유된 슬러지를 응집제로 응집시켜 무한궤도 형상으로 되고 동물의 털을 압축시켜 만든 펠트로 구성된 상하 압착벨트 사이에 투입하여 탈수시키고 펠트로된 상하압착벨트 내측에 무한궤도형상의 체인에 다공체인 탈수안내구가 부착되어 펠트내측에서 펠트를 가압할수 있게 만든 내측압착벨트를 설치하여 탈수작용을 하는 상하압착벨트를 중복 압착시킬수 있게 구성하여 슬러지에 포함된 수분을 효과적으로 탈수시킬수 있게 한 펠트타입의 슬러지 탈수장치에 관한 것이다.The present invention relates to a sludge dewatering apparatus for continuously dewatering the sludge mixed in the wastewater of the plant, and more particularly, the sludge contained in the wastewater in the wastewater is made by agglomerates into an orbital shape and composed of felt made by compressing animal hair Dehydration by putting in between the upper and lower pressing belts, and inside and outside the upper and lower pressing belts, a dehydration guide, which is a porous body, is attached to the endless orbital chain to install the inner pressing belt made to press the felt inside the felt. The present invention relates to a felt-type sludge dewatering device configured to be able to compress the pressing belts in duplicate so that the water contained in the sludge can be effectively dehydrated.

종래의 공장폐수에 함유된 슬러지 탈수장치는 구멍이 천공된 벨트형상으로된 흡수여과판위에 압착벨트를 설치하여 그 사이로 슬러지를 통과시켜서 슬러지에 함유된 수분이 흡수여과판의 압착여과작용으로 탈수되게 구성하고 탈수된 슬러지를 흡수여과판과 압착벨트사이로 배출시키는 장치로 되어 있다.따라서 이러한 탈수장치는 슬러지내의 수분을 완벽하게 압착하여 탈수시키지 못하는 결점이 있다.The sludge dewatering device contained in the conventional plant wastewater is provided with a compression belt on the belt-shaped absorption filter plate with perforated holes, and the sludge is passed therebetween so that the water contained in the sludge is dehydrated by the compression filter action of the absorption filter plate. The dewatered sludge is discharged between the absorption filtration plate and the pressing belt. Therefore, the dewatering device has a drawback in that the water in the sludge is not completely depressed and dehydrated.

상기와 같이 구성된 본 발명은 탈수장치전방에 배치한 폐수탱크(7)에 응집제 투입장치(8)를 갖추어서 폐수에 응집제를 투입하므로서 공지된 방법으로 폐수속에 함유된 슬러지를 응집시킬수 있고 응집된 슬러지는 별도의 슬러지이송벨트(40)(41)로 운반시켜 상하압착벨트(1)(1a)의 투입구(24)에 투입하면 상하압착벨트가 투입구에서 배출구쪽으로 회전하면서 서로 접촉되는 접촉면 사이로 슬러지가 투입되어 상하 압착벨트를 구성하고 있는 펠트층의 압착작용을 통해 슬러지가 압착되어 수분은 펠트층을 통해 여과되고 슬러지는 펠트층사이에 남아 케익상태로 상하압착벨트사이를 통과하여 배출구(25)로 배출되기 때문에 슬러지를 연속적으로 탈수하게 되며 상하압착벨트(1)(1a)의 펠트층내측에는 펠트내면에서 외측방향으로 펠트에 압력을 주는 내측압착벨트(20)(21)가 설치되어 내측압착벨트의 압착면 내측에 있는 가압판(22)(23)에 유체압실린더가 장치되어 있으므로 유체압실린더(30)(31)에 가압신호를 주어 펠트의 압착면을 더욱 강하게 압착시킬수 있고 이 과정에서 펠트층을 통과한 수분은 내측압착벨트(20)(21)의 체인(2)(2a)외면에 부착되어 있는 구멍(2b)이 천공된 관체형상의 탈수안내구(2c)를 통해 착출된 수분이 탈수안내구(2c)내측으로 유입되어 양측방으로 배출되기 때문에 펠트의 압착과정에서 짜여진 수분이 그 자리에 머물지 않고 외부로 신속하게 배출되는 효과를 얻을수 있어서 펠트층을 통과하는 슬러지의 함유수분을 완전하게 탈수시킬수 있고 탈수안내구(2c)는 그 폭이 체인하나의 폭보다 좁기 때문에 체인의 굴곡작용에 영향을 기치지 않고 탈수안내작업을 수행할수 있다.이로인해 슬러지의 탈수를 연속적으로 수행하면서 폐수를 처리할수 있게 되는 탈수장치를 얻는 것이다.The present invention configured as described above is provided with a flocculant injector 8 in the wastewater tank 7 disposed in the front of the dehydration apparatus, so that the sludge contained in the wastewater can be aggregated by a known method and the flocculated sludge is aggregated. Is transported to a separate sludge conveying belt (40) (41) and put into the inlet 24 of the upper and lower compression belt (1) (1a), the upper and lower compression belt rotates from the inlet to the discharge port, the sludge is introduced between the contact surface The sludge is compressed through the action of the felt layer constituting the up and down compression belt, and the water is filtered through the felt layer and the sludge remains between the felt layers and passes between the up and down compression belt in the cake state and discharged to the outlet 25. Since the sludge is continuously dewatered, the inner compression bell which presses the felt from the inside of the felt to the outside of the felt layer on the inside of the felt layer of the up-and-down compression belt (1) (1a) (20) (21) are installed and the pressure plate (22) (23) is installed on the pressure plate (22) (23) inside the pressing surface of the inner compression belt, so that the pressure signal is applied to the fluid pressure cylinder (30) (31) to press the felt. The surface can be pressed more strongly, and the water passing through the felt layer in this process is dehydrated in the shape of a tubular body with holes 2b attached to the outer surface of the chains 2, 2a of the inner compression belts 20, 21. Since the water extracted through the guide 2c flows into the dehydration guide 2c and is discharged to both sides, it is possible to obtain the effect of the moisture squeezed out during the pressing process of the felt to be discharged to the outside quickly without remaining in place. The water contained in the sludge passing through the felt layer can be completely dehydrated, and the dehydration guide 2c can be dehydrated and guided without affecting the bending action of the chain because its width is narrower than that of one chain. This allows sludge dewatering While continuously carried out to obtain the dewatering device being able to process the waste water.
