At the same time, the rotation of the screw (S) in the state in close contact with the inner wall surface (12, 12 ') of the outer cylinder (9) (9') is made.

여기서 설명되지 아니한 부호, 17,17'는 베어링이며, 18,18'는 찌꺼기 유출구와 탈수유출구를 각각 표시한다.Reference numerals 17 and 17 ', which are not described herein, are bearings, and 18 and 18' are respectively indicating the dregs outlet and the dehydration outlet.

이와같이 구성된 본 발명을 실시함에 있어 그 작용효과는 다음과 같다.In carrying out the present invention configured as described above, the effects are as follows.

즉 모우터(M)을 가동시키면 구동기어(G)(G')와 체인(3)(3')으로 연결된 축수부(6)(6')의 대소체인기어(4)(4')에 의해 외통(9)(9')과 그 내부로 장설된 스크루(S)는 서로 그 회전속도(스크루가 외통에 비해 초고속으로 회전함)을 달리하며 회전하는 것이다.In other words, when the motor M is operated, the gears 4 and 4 'of the bearing parts 6 and 6' are connected to the drive gears G and G 'and the chains 3 and 3'. By the outer cylinder (9) (9 ') and the screw (S) installed in the inside is to rotate at different speeds (screws rotate at a very high speed compared to the outer cylinder).

이때 상기 축수부(6)의 중앙으로 천공된 급수공(5)을 통해 폐수가 →로 방향으로 급수되게 하면 상기 폐수는 축수부(6)에 의한 스크루(S)의 고속회전으로 인한 원심력에 의해 배수공(5')으로 부터 외통(9)(9')의 내벽면(12)(12') 방향을 향해 확산 분포되는 것이다.At this time, if the waste water is supplied in the direction of → through the water supply hole 5 drilled into the center of the water storage unit 6, the waste water is caused by centrifugal force due to the high speed rotation of the screw S by the water storage unit 6. The diffusion is distributed from the drain hole 5 'toward the inner wall surfaces 12 and 12' of the outer cylinders 9 and 9 '.

그러나 상기 외통(9)(9')은 스크루(S) 보다도 그 회전속도가 느리기 때문에 폐수중에 함유된 찌꺼기는 직선형의 환봉(7)(7')으로 구성한 외통(9)(9')의 내벽면(12)(12')이 본 발명 제3도에서 보는 바와같이 환봉(7)(7')의 내측이 지분상으로 가공되어 있고 이에 스크루(S)의 주연이 밀착된 상태로 회전함에 따라 후렌지캡(14)과 토출구(15')를 갖는 토출캡(15)이 위치한 앞쪽 밀려 이송되면서 동체(1)의 하방으로 형성한 찌꺼지 유출구(18)를 통해 유출되는 한편, 상기 외통(9)(9')의 환봉(7)(7')과 사이의 틈새(13)(13')로 빠진 탈수는 동체(1)의 하방으로 형성시킨 탈수유출구(18')로 각각 분리 유출되는 것이다.However, since the outer cylinders 9 and 9 'have a lower rotational speed than the screws S, the wastes contained in the waste water are in the inner cylinders 9 and 9' composed of straight round rods 7 and 7 '. As the wall surface 12, 12 'is shown in FIG. 3 of the present invention, the inner side of the round bar 7, 7' is processed into equity and the peripheral edge of the screw S is rotated in close contact. While the front cap 9 having the flange cap 14 and the discharge cap 15 having the discharge port 15 'is pushed forward and flows out through the dregs outlet 18 formed below the fuselage 1, the outer cylinder 9 ( The dewatered drained out by the gaps 13 and 13 'between the round rods 7 and 7' of 9 ') is separated and discharged to the dehydration outlet 18' formed below the fuselage 1, respectively.

또한 본 발명을 제4도에 도시한 다른 실시예의 외통(9)(9')에서는 상기와 같은 효과가 제공되도록 환봉(8)(8')을 코일식으로 나권하고 그 내벽면(12)(12')을 지분가공하여 주므로서 외통(9)(9')의 내부로 장설된 축수부(6)에 의해 스크루(S)의 주연이 이와 밀착 회전될 수 있게 구성한 것에 의해 페수중의 찌꺼기와 탈수를 분리처리할 수 있다.In addition, in the outer cylinder (9) (9 ') of another embodiment of the present invention shown in FIG. 4, the rods (8) and (8') are coiled spirally to provide the same effect as above, and the inner wall surface (12) ( 12 '), so that the periphery of the screw (S) can be rotated in close contact with this by the bearing part 6 installed inside the outer cylinder (9) and (9'). Dewatering can be separated off.

따라서 본 발명을 축수부(6)(6')에 구성한 대소체인기어(4)(4')에 의해 외통(9)(9')의 내부로 장설되어 이와 결합된 스크루(S)와 외통(9)(9')과는 회전속도를 달리하면서 상기 스크루(S)의 회전속도로 인한 원심력을 이용하는 본 발명의 폐수처리장치는 단일구성체내에서 폐수중의 찌꺼기와 탈수의 분리작용이 동시에 이루어지도록함과 동시에 외통(9)(9')을 봉상으로 된 직선형의 환봉(7)(7')이나 또는 코일식의 환봉(8)(8')으로 연접나권하여 구성하고 그 내벽면(12)(12')은 실린더와 같은 역할을 행하도록 매끄럽게 하여 이와 밀착회전하는 스크루(S)에 의해 찌꺼기의 원활한 이송작용과 환봉(7)(7')(8)(8')과 사이에 틈새(13)(13')를 통한 탈수작용의 효과를 함께 제공하는 한편 외통(9)(9')의 각 후렌지부(10)(10')에 의해 볼트닛트(11)(11')로 외통(9)(9')수를 가감구성할 수 있기 때문에 처리하고자 하는 폐수량에 따라 외통의 크기를 달리할 수 있으므로 페수처리에 따른 신속성과 경제성을 같이하는 이점이 있다.Therefore, the screw (S) and the outer cylinder (3) installed in the inside of the outer cylinder (9) and 9 'by the large and small chain gear (4) (4') constituted in the bearing part (6) (6 '). 9) (9 ') using a centrifugal force due to the rotational speed of the screw (S) while varying the rotational speed of the wastewater treatment apparatus of the present invention so that the separation action of the debris and dehydration in the wastewater in a single body at the same time At the same time, the outer cylinder (9, 9 ') is formed by connecting or winding with a straight round bar (7) (7') or a coiled round bar (8) (8 ') in the form of a rod, and the inner wall surface (12).
