It is preferable to configure so that the predetermined interval position can be moved along the filter surface. Therefore, when the dewatering cylinder 2 is rotated, the rotating cylinder 68 coupled to the driven friction car 62 of the transmission 52 is rotated at a different speed than the dehydrating cylinder 2, and the number of rotations Due to the difference of the compression roll 8 coupled to the periphery of the rotating cylinder 68, the filter 4 in which the compression roll 8 is in close contact with each other is relative to each other. Accordingly, the compression roll 8 simultaneously rotates and revolves along the inner surface of the filter 4, thereby crushing the sludge supplied into the filter 4. In this case, a separate support frame is provided on the outer circumferential surface of the filter 4 to correspond to the position at which the compression roll 8 moves, thereby preventing the filter 4 from being pressed and deformed by the compression roll 8.

In addition, the bottom surface of the housing 72 is provided with a discharge hopper 74 for discharging the sludge discharged to the discharge port 18 of the dehydration cylinder 2, and drain holes 26 and 28 of the dehydration cylinder 2. A drain hopper 76 is formed to discharge the discharged discharged water, and a partition 78 is formed between the discharge hopper 74 and the drain hopper 76 to prevent the sludge and the discharged water from being mixed.

따라서, 상기 구동모터를 구동하면 상기 탈수통체(2)와 이 탈수통체(2)의 내부에 장착된 필터(4)가 회전하게 되고, 상기 압축롤(8)이 상기 탈수통체(2)와는 다른 회전수로 필터(4)의 내측면을 따라 자전과 공전을 하게 된다. 이때, 상기 고정샤프트부재(6)와 배출덕트(72)는 회전하지 않고 정지되어 있다. 그리고, 상기 슬러지투입관(38)을 통해 상기 고정샤프트부재(6)의 중공부(40)로 슬러지를 공급하면, 이 슬러지는 고정샤프트부재(6)에 형성된 분출구(42)와 상기 회전통체(68)의 배출공(71)을 통해 상기 필터(4)의 내부로 공급되어 탈수통체(2)와 함께 회전되며 일차로 탈수된다.Therefore, when the driving motor is driven, the dehydrating cylinder 2 and the filter 4 mounted inside the dehydrating cylinder 2 rotate, and the compression roll 8 is different from the dehydrating cylinder 2. Rotation and revolution are performed along the inner surface of the filter 4 at the rotational speed. At this time, the fixed shaft member 6 and the discharge duct 72 is stopped without rotating. Then, when the sludge is supplied to the hollow portion 40 of the fixed shaft member 6 through the sludge inlet pipe 38, the sludge is a jet 42 and the rotating cylinder formed in the fixed shaft member (6) It is supplied to the inside of the filter (4) through the discharge hole 71 of the 68 is rotated together with the dehydrating cylinder (2) and dewatered primarily.

Then, the dewatered sludge is continuously supplied into the dehydrating cylinder (2) and pushed by the sludge moving along the inner surface of the filter (4) to be discharged to the outlet (18), and then to the housing 72 It is discharged to the discharge hopper 74 formed.

이때, 상기 임펠러(68)에 의해 발생된 부압에 의해 필터(4)의 내측으로 흡입되는 공기에 의해 슬러지가 필터(4)의 내측면에 달라붙거나, 슬러지 찌꺼기가 필터(4)의 슬릿(34)사이에 끼어 필터(4)가 막히는 것을 방지할 수 있다.At this time, the sludge adheres to the inner surface of the filter 4 by the air sucked into the filter 4 by the negative pressure generated by the impeller 68, or the sludge dregs of the slits of the filter 4 It is possible to prevent the filter 4 from being clogged by being sandwiched between 34).

그리고, 상기 슬러지에서 탈수된 물은 상기 내통체(12)에 형성된 배수구(26,28)를 통해 상기 집수쳄버(22)에 일차 저장된 후, 상기 외통체(14)에 형성된 배수구(26,28)를 통해 배수되며, 상기 배수구(28)로 배출된 배출수는 상기 하우징(72)에 형성된 배수호퍼(76)를 통해 외부로 배출된다.The water dewatered from the sludge is first stored in the water collecting chamber 22 through drain holes 26 and 28 formed in the inner cylinder 12, and then drain holes 26 and 28 formed in the outer cylinder 14. Drained through, the discharged water discharged to the drain 28 is discharged to the outside through the drain hopper 76 formed in the housing (72).
