상기 내부 드럼스크린(20)은 매쉬크기가 적은 형태로 형성하고 외부 드럼스크린(10)은 매쉬크기가 내부 드럼스크린(20) 보다 큰 형태로 형성하는 것이 단계적인 탈수기능을 용이하게 수행할 수 있도록 하는 것이다.The inner drum screen 20 is formed to have a smaller mesh size and the outer drum screen 10 is formed to have a larger mesh size than the inner drum screen 20 so that the stepwise dehydration function can be easily performed. It is.

또한 내부 드럼스크린(20) 입구 측에 위치하는 지지축관(21)에 끼워지는 공급관(40)과의 틈새로 누수를 방지하기 위하여 실링처리가 이루어지는 것이 바람직하다.In addition, it is preferable that a sealing treatment is performed to prevent leakage due to a gap with the supply pipe 40 fitted into the support shaft pipe 21 positioned at the inlet side of the inner drum screen 20.

상기 외부 드럼스크린(10)의 하부에는 배수되는 물을 수거하여 배송할 수 있도록 집수조(60)를 구비하고, 외부 드럼스크린(10)의 출구 측의 하방에는 내,외부 드럼스크린(10,20)을 통해 걸러져 빠져나오는 협잡물인 이물질을 배송위치로 배출되도록 배송슈트(70)를 별도로 구비할 수 있는 것이다.The lower portion of the outer drum screen 10 is provided with a collecting tank 60 to collect and deliver the drained water, the inner and outer drum screen (10, 20) below the outlet side of the outer drum screen (10) It is to be provided with a shipping chute 70 to discharge the foreign matters that are caught through the filtered out through the delivery location.

도 3,4에서와 같이 상기 내,외부 드럼스크린(10,20)을 서로 다른 회전수 및 반대방향으로 회전시키도록 하기 위한 구동수단(50)에 대하여 살펴보면,
모터(51)의 구동축(52)에 축설한 소기어(53)를 외부 드럼스크린(10)의 한 측단에 설치하는 대기어(13)에 치합하여 외부 드럼스크린(10)을 감속 회전시키도록 구성하며, 상기 구동축(52)의 적정위치에 축설하는 스프로킷(54)과 내부 드럼스크린(20)에 고정한 타측의 지지축(22) 단부에 축설한 스프로킷(55)을 체인(56)에 의하여 연동하도록 구성한 것이다.Referring to the driving means 50 for rotating the inner and outer drum screens 10 and 20 at different rotational speeds and in opposite directions as in FIGS. 3 and 4,
The small gear 53 arranged on the drive shaft 52 of the motor 51 is engaged with the standby gear 13 installed at one side end of the external drum screen 10 so as to decelerate and rotate the external drum screen 10. The sprocket 54 arranged at the proper position of the drive shaft 52 and the sprocket 55 arranged at the end of the supporting shaft 22 fixed to the inner drum screen 20 are interlocked by the chain 56. It is made up.

상기 내부 드럼스크린(20)은 내면에 미세구멍으로 형성된 스크린판(20a)의 강도 유지를 위해 긴 장공을 형성한 보강판(20b)을 부착한 이중판체로 형성할 수 있다.The inner drum screen 20 may be formed as a double plate body to which a reinforcing plate 20b having a long long hole is attached to maintain the strength of the screen plate 20a formed with micro holes on the inner surface thereof.

이와 같이 구성한 본 발명에 대한 작동상태를 구체적으로 설명하면 다음과 같다.Referring to the operating state of the present invention configured as described above in detail.

먼저 모터(51)를 포함한 구동수단(50)이 구동하면 내,외부 드럼스크린(10,20)이 각각 서로 다른 회전수 및 반대방향으로 회전하게 되는 상태에서 공급관(40)을 통해 이송물이 내부 드럼스크린(20)을 지지하는 지지축관(21)을 통해 유입되어 지지축관(21)의 내측 단부 둘레에 형성된 공급공(21a)을 통해 이송물이 내부 드럼스크린(20)의 내부로 공급이 이루어진다.First, when the driving means 50 including the motor 51 is driven, the conveyed material is fed through the supply pipe 40 while the inner and outer drum screens 10 and 20 are rotated in different directions and in opposite directions, respectively. The feed is supplied into the internal drum screen 20 through a supply hole 21a which is introduced through the support shaft tube 21 supporting the drum screen 20 and formed around the inner end of the support shaft tube 21. .

그리고 회전하는 내부 드럼스크린(20)으로 유입된 이송물은 나선 익편(23)에 의해 이물질인 협잡물들이 이송되면서 협잡물에 포함된 수분은 드럼스크린 배수공을 통해 배수가 이루어지는데 드럼스크린(20)이 세목형태로 되어 있어 이물질이 걸리지 않고 머리카락 등은 이송중에 엉키면서 뭉쳐져 이송이 이루어진다.Then, the conveyed material introduced into the rotating inner drum screen 20 is transferred to the contaminants which are foreign matters by the spiral blades 23, and the moisture contained in the contaminated matter is drained through the drum screen drain hole. Because it is in the form, foreign substances are not caught, and hairs are tangled during transportation and are gathered together to transfer.

이러한 과정에 의하여 이동된 이물질들은 내부 드럼스크린(20)의 후단에 이르게 되면 단부 둘레에 형성한 배출공(24)를 통해 배출되어 회전상태를 갖는 외부 드럼스크린(10)에 유입됨에 따라 다시 처리물은 나선 익편(11)에 의해 이물질인 협잡물들이 이송되면서 협잡물에 포함된 수분은 2차적으로 드럼스크린의 배수공을 통해 배수가 이루어진 후 외부로 이물질인 협잡물이 외부 드럼스크린(20)으로부터 빠져 나가 외부로 배출되며, 배출되는 이물질은 별도로 구비되는 배출로를 통해 배출위치로 배출하게 되는 것이고 상기 외부 드럼스크린(10)을 통해 배수되는 물은 그 하방에 위치한 집수조(60)에 모아져 별도의 처리시설로 배송하여 처리되거나 배출을 하는 것이다.When the foreign matters moved by this process reach the rear end of the inner drum screen 20, the discharged matter is discharged through the discharge hole 24 formed around the end and flows into the outer drum screen 10 having the rotational state. As the contaminants that are foreign matters are transferred by the silver spiral blade 11, the moisture contained in the contaminants is secondly drained through the drain hole of the drum screen, and then the foreign matters are escaped from the outer drum screen 20 to the outside. The foreign substances discharged are discharged to a discharge position through a discharge path provided separately, and the water discharged through the external drum screen 10 is collected in a collecting tank 60 located below and delivered to a separate treatment facility. To be treated or discharged.

위와 같이 투입되는 이물질이 왕복하는 과정을 거치면서 이물질에 포함된 수분이 거의 빠져나가게 되고 이물질을 제거하게 되는 것이다.As the foreign material introduced as above goes back and forth, the moisture contained in the foreign material is almost drained and the foreign material is removed.
