본 고안은 오물이나 분뇨등의 각종 폐기물 정화처리 공정과정중 협잡물 선별 공정과정에 의해 분리 이송되는 섬유조각이나 나무조각, 폐지등의 각종 협잡물을 처리한 후 발생된 슬럿지에 함유된 수분을 탈수함에 있어서, 탈수조내의 슬럿지 중에 회전 스크린을 침적시켜 여과된 물은 중력등에 의해 배출하며, 슬럿지를 분리 처리할 수 있도록 한 슬럿지의 탈수장치에 관한 것이다.The present invention dehydrates the water contained in the sludge produced after treating various kinds of contaminants such as fiber fragments, wood fragments, and waste paper which are separated and transported by the process of sorting the contaminants during various waste purification processes such as dirt and manure. The present invention relates to a sludge dewatering device which deposits a rotating screen in sludge in a dewatering tank and discharges the filtered water by gravity, etc., so that the sludge can be separated and processed.

종래의 슬럿지 탈수장치는 제6도에서와 같이 슬럿지 공급조(1)의 하방에 하 여과포(101)를 설치하고, 이 하 여과포(101)의 일측면에는 상 여과포(102)를 접면 상태로 설치하며, 사익 하 여과포(101)의 하방에 세척기(103)를 설치하여 구성되어 있었는 바, 이상과 같은 종래의 것을 상기 슬럿지 공급조(1)에서 함수량이 높은 슬럿지(104)를 망상의 하 여과포(101)에 공급시킨 후 이를 이송하게 되면, 제6도에서와 같이 슬럿지(104)가 망상의 하 여과포(101)를 따라 가압위치까지 이동되고 이 가압위치에서부터 상 여과포(102)와 하 여과포(101) 사이에 상기 슬럿지(104)가 끼워지는 상태로 된다.In the conventional sludge dewatering device, as shown in FIG. 6, the lower filter cloth 101 is installed below the sludge supply tank 1, and the upper filter cloth 102 is installed on one side of the lower filter cloth 101 in a folded state. In addition, the washing machine 103 is installed below the filter cloth 101 under the mid-bar, and the conventional method as described above has a sludge 104 having a high water content in the sludge supply tank 1. When it is supplied to 101 and then conveyed, the sludge 104 is moved along the reticulated lower filter cloth 101 to the pressurized position as shown in FIG. 6 and from this pressurized position, the upper filter cloth 102 and the lower filter cloth 101 The sludge 104 is sandwiched between the holes.

상기와 같이 하 여과포(101)와 상 여과포(102) 사이에 끼워진 슬럿지(104)는 상기 여과포(101)(102)들의 압축력과 이동에 의하여 탈수가 이루어지며, 상기 여과포(101)(102)들의 접면 거리와 속도에 따라 탈수율이 높거나, 낮게 되고 이 탈수율은 탈수전에 미리 설정하게 되어 있다.The sludge 104 sandwiched between the lower filter cloth 101 and the upper filter cloth 102 as described above is dehydrated by the compressive force and movement of the filter cloths 101 and 102, and the filter cloths 101 and 102 are The dehydration rate is high or low depending on the contact distance and speed, and the dehydration rate is set in advance before dehydration.

또, 상기와 같이 탈수가 완료된 슬럿지(104)는 상기 여과포(101)(102)들의 끝단으로 배출되며, 상기 압착작용에 의해 상기 하 여과포 이어(101)의 망상에는 슬럿지가 끼게 되고 다음의 탈수를 위하여 망상의 콘베이어에 끼워진 슬럿지를 제거해야 하는데, 이를 위한 세척기(103)가 구성상 하 여과포(101)의 하방에 설치되어야만 하므로서 고압의 세척수가 슬럿지와 함께 비산되는 폐단이 있었으며, 또 슬럿지가 망상의 하 여과포에 끼워지는 방향으로 고압 세척수를 가압하게 되므로 오히려 슬럿지가 망상의 하 여과포에 끼워지는 방향으로 고압 세척수를 가압하게 되므로 오히려 슬럿지가 상기 슬럿지가 상기 망상에 강력히 끼워질 염려가 있었고, 부분적으로는 상기 하 여과포(101)내로 들어가게 되어 슬럿지에서 탈수되는 수분을 여과해야 하는 폐단이 있었을 뿐만 아니라 탈수율이 장치의 부피에 비하여 현저히 낮게 되며, 또 소음이 발생되었고 상기의 방법으로 세척하므로서 세척수의 소모량이 많게 되는 점등의 문제점이 있었다.In addition, the sludge 104, which has been dehydrated as described above, is discharged to the ends of the filter cloths 101 and 102, and the sludge is caught in the mesh of the lower filter foil 101 by the compression action, and the next dehydration is performed. In order to remove the sludge inserted into the reticular conveyor, the washing machine 103 for this configuration must be installed under the lower filter cloth 101, so there was a closed end where the high-pressure washing water was scattered together with the sludge. Since the high pressure washing water is pressurized in the direction to be inserted into the lower filter cloth, the sludge pressurizes the high pressure washing water in the direction to be inserted into the lower filter cloth, so that the sludge may be strongly inserted into the mesh, and partially There was a closed end to enter the lower filter cloth 101 to filter the water dehydrated in the sludge Not only is the dehydration rate is significantly lower than the volume of the device, and there is a problem of light were generated noise which the consumption of hameuroseo washed with the wash water of the process a lot.

또한, 스크류 콘베이어를 이용하는 탈수장치가 안출된바 있으나, 이는 슬럿지등의 탈수를 상기 스크류 콘베이어에만 의존하므로서 장치의 규모에 비하여 탈수 효과가 극히 저조하였을 뿐만 아니라, 그 청소가 어려웠고 탈수시 다량의 슬럿지드이 함유된 상태가 되므로서 이를 다시 여과시켜야 하는 문제점이 있었다.In addition, a dewatering device using a screw conveyor has been devised, but this is dependent on the screw conveyor for dehydration such as sludge, so that the dewatering effect is extremely low compared to the size of the device, and the cleaning is difficult, and a large amount of sludge is used when dewatering. There was a problem to be filtered again because it is in the contained state.

본 고안은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로 장치의 부피를 줄이면서 슬럿지중의 수분을 회전 스크린으로 여과ㅡ 탈수할 수 있도록 하고 또, 상기 슬럿지를 2단계에 걸쳐 탈수 하도록 하므로서 탈수효율을 높일 수 있도록 하며, 탈수속도를 빠르게 할 수 있도록 하며, 또한 전처리 공정의 협잡물에 함유된 모래등을 분리, 제거할 수 있도록 한 것인바, 이를 이하에서 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been devised in view of the above-mentioned problems in the related art, and it is possible to filter and dehydrate water in the sludge with a rotating screen while reducing the volume of the apparatus, and dewatering by allowing the sludge to be dehydrated in two stages.

이상과 같이 구성된 본 고안은 제1도에서와 같이 슬럿지 공급조(1)에서 수분이 다량 함유된 슬럿지를 유입구(3)를 통해 탈수조(2)에 공급하게 되면, 상기 공급되는 슬럿지의 충력과 구동모터(22)에 의해 축(14)과 함께 회전되는 회전스크린(12)의 회전력에 의해서 상기 슬럿지에 함유된 수분이 회전스크린(12)내로 탈수되며, 상기 슬럿지는 회전 스크린(12)의 표면 외주에 붙게 된다.When the present invention configured as described above is supplied to the dewatering tank (2) through the inlet (3) containing a large amount of water in the sludge supply tank (1) as shown in Figure 1, The moisture contained in the sludge is dewatered into the rotating screen 12 by the rotational force of the rotating screen 12 which is rotated together with the shaft 14 by the drive motor 22, and the sludge is the surface of the rotating screen 12. It is attached to the outer circumference.

이때, 상기 회전스크린(12)에 붙은 슬럿지는 계속 공급되는 타 슬럿지의 중력과 회전 스크린(12)의 회전력에 의해 역삼각형 탈수공(13)으로 흡입되는 형태가 되며, 상기 흡입력은 회전 스크린(12)내에 설치된 유출관(17)과 사이폰식 배출구(18) 또는 배출펌프(23)에 의해 발생되므로 슬럿지에 함유된 수분이 상당량 탈수되고, 일부 슬럿지도 함게 상기 회전 스크린(12)내로 유입되며, 상기 탈수된 수분은 유출관(17)을 통해 배출된다.At this time, the sludge attached to the rotary screen 12 is in the form of being sucked into the inverted triangle dewatering hole 13 by the gravity of the other sludge and the rotational force of the rotary screen 12, the suction force is the rotary screen 12 Is generated by the outlet pipe 17 and the siphon type discharge port 18 or the discharge pump 23 installed in the) and the water contained in the sludge is dehydrated in a considerable amount, and some of the slits are also introduced into the rotary screen 12, Dehydrated water is discharged through the outlet pipe 17.

상기와 같은 작용에 의해 탈수된 슬럿지의 대부분은 탈수조(2) 하방의 침적통로(4)를 따라 하강하여 스크류케이싱(5)로 침적되며, 일부 슬럿지는 상기 회전스크린(12)의 외주표면에 붙어 있게 되는데, 이 회전스크린(12)에 붙어있는 슬럿지는 회전 스크린(12)의 회전과 탈수조(2) 상부의 스크레이퍼(15)와 브러시(16)에 의해 제거된다.Most of the sludge dewatered by the above action is lowered along the deposition passage 4 below the dewatering tank 2 and deposited in the screw casing 5, and some slits are formed on the outer circumferential surface of the rotary screen 12. The sludge attached to the rotary screen 12 is removed by the rotation of the rotary screen 12 and the scraper 15 and the brush 16 on the dewatering tank 2.

한편, 상기 침적통로(4)를 따라 스크류 케이싱(5)으로 모여진 슬럿지는 회전축(20)에 의해 회전되는 스크류 콘베이어(19)로 공급되며, 이 간격이 점점 좁아지는 스크류 콘베이어(19)의 회전에 의해 압축되어 통공(6)으로 2차 탈수가 되고 탈수된 슬럿지는 장치의 일측방으로 배출되며, 상기 스크류 케이상(5)에서 압출탈수된 수분은 쟈켓(7)내에 모여지게 되고, 소제구(8)와 배출콕(24)으로 상기 쟈켓(7)내부를 청소하게 된다.On the other hand, the sludge collected in the screw casing 5 along the immersion passage 4 is supplied to the screw conveyor 19 is rotated by the rotary shaft 20, the gap is gradually narrowed to the rotation of the screw conveyor 19 And the dewatered sludge is discharged to one side of the apparatus by being compressed to the through hole (6), and the water extruded and dehydrated on the screw cage (5) is collected in the jacket (7), and 8) and the discharge cock 24 to clean the inside of the jacket (7).

또, 상기 스크류 콘베이어(19)의 세척은 이의 일측 상방에 설치된 분사구(21)를 가동시켜 세척하게 되며, 상기와 같은 작용도중 회전스크린(12)등 막혀 탈수조(2)내의 수위가 높아지면, 이를 감지센서(10)가 감지하여 레벨스위치(9)를 작동시키게 되고, 레벨스위치(9)의 작동에 따라 슬럿지의 공급은 차단되면서 경보기(11)에 의해 경보음이 발생되므로 이를 감지한 관리자가 점검하여 재가동 시키게 되는 것이다.In addition, the washing of the screw conveyor 19 is to operate by washing the injection port 21 installed above one side thereof, and if the water level in the dehydration tank (2) is clogged during the operation such as the rotating screen 12, The detection sensor 10 detects this to operate the level switch 9, and the alarm is generated by the alarm 11 while the supply of the sludge is cut off according to the operation of the level switch 9. It will be checked and restarted.

또한, 상기 배출펌프(23)가 작동되도록 하므로서 탈수된 수분등의 배출을 신속하게 하여 탈수장치의 고장등을 예방하게 되고, 상기 배출펌프(23)의 작동으로 수위가 다시 낮아지면 레벨스위치(9)가 차단되면서 재가동하게 되는 것이다.In addition, the discharge pump 23 is operated to quickly discharge the dehydrated water and the like to prevent the failure of the dehydration device, and the level of the lower level switch (9) when the water level is lowered again by the operation of the discharge pump (23) ) Will be shut down and restarted.
