To this end, according to the pump device of an embodiment of the present invention, a hopper for injecting sludge is provided in an opened upper part of a screw housing in which a pair of screw conveyors separated from each other is embedded, and hydraulic cylinders connected through a three-way valve pipe are provided in a line in each of the screw conveyors such that the sludge is introduced to the corresponding cylinder through each three-way valve pipe when each of the screw conveyors is rotated and then, is transferred through a discharge pipe vertically connected to the three-way valve pipe. According to the present invention, a pair of hollow rotary pipes individually surrounding each of the screw conveyors is rotatably provided in the screw housing. In addition, the backflow of the sludge is prevented when the hopper and the screw conveyors are blocked by rotation of the rotary pipes in a process of introducing the sludge into each of the screw conveyor through an opening formed in each of the rotary pipes and filling each cylinder with the sludge.

Description

슬러지 이송용 펌프장치{Pump unit for sludge transfer}Pump unit for sludge transfer

본 발명은 슬러지 이송용 펌프장치에 관한 것으로서, 더욱 상세하게는 호퍼에서 공급되는 슬러지가 스크류컨베이어를 타고 실린더로 압송되는 과정에서 압축된 슬러지가 호퍼 쪽으로 역류되지 않도록 상기 스크류컨베이어와 호퍼의 사이를 간헐적으로 개폐하는 수단을 마련함으로써, 실린더에 압축력이 걸리더라도 슬러지가 호퍼 쪽으로 역류되지 않으므로 슬러지 이송효율을 높일 수 있는 슬러지 이송용 펌프장치에 관한 것이다.The present invention relates to a pump device for transporting sludge, and more specifically, intermittently between the screw conveyor and the hopper so that the compressed sludge does not flow back toward the hopper while the sludge supplied from the hopper is pushed to the cylinder on a screw conveyor. By providing a means to open and close by, it relates to a pump device for sludge transfer that can increase the efficiency of the sludge transfer because the sludge does not flow back toward the hopper even if a compression force is applied to the cylinder.

일반적으로 버려지는 음식물 찌꺼기는 수거과정에서 음식물 이외의 이물질(병, 종이, 캔, 나무젓가락 등)이 썩여 있기 때문에 분리 수거가 잘 않 될 경우 음식물 쓰레기 처리장에서 이를 운반 이송할 때 장치에 무리를 주어 쉽게 고장 나는 원인이 되었다.Generally, food waste that is wasted is rotten by foreign matter (bottles, paper, cans, wooden chopsticks, etc.) other than food during the collection process. It easily caused the failure.

종래에는 음식물 쓰레기와 같은 점도가 높은 슬러지를 이송시키기 위해 모노펌프 같은 펌프를 이용한 기술이 국내 실용신안 등록 제174569호로 등록된 바 있다. 그러나 종래의 이송장치는 기계적인 펌프를 이용하는 것이기 때문에 음식물 쓰레기 등에 금속성 또는 단단한 이물질이 포함되어 있을 경우 펌프를 구성하는 부품들이 파손되거나 과부하가 걸려 수명이 단축되는 등의 문제가 있었다. 그리고 펌프 내부에 음식물 찌꺼기가 항상 남아 있으므로 기기를 작동하지 않을 경우 쓰레기가 부패되면서 악취가 발생되는 등의 문제점이 있었다.Conventionally, a technique using a pump such as a monopump to transfer sludge with a high viscosity such as food waste has been registered as a domestic utility model registration No. 174569. However, since the conventional transfer device uses a mechanical pump, there is a problem in that, when metal or hard foreign matter is contained in food waste, parts constituting the pump are damaged or overloaded, resulting in shortened life. In addition, since food waste is always left inside the pump, there is a problem in that, when the device is not operated, garbage is spoiled and odor is generated.

종래 특허 제733790호는 점도가 높은 음식물쓰레기 및 하수종말처리장의 침전물인 슬러지를 관로상에서 진공 흡입하여 이송시키되 펌핑수단을 병설하여 한쪽에서 흡입하는 동안 한쪽은 배출이 이뤄지도록 하여 슬러지를 연속성있게 관로에서 이송시킬 수 있으며, 흡입 및 배출관로의 개폐시 별도의 절환밸브를 이용하여 신속하게 절환되도록 하여 흡입 및 배출량을 최대한 높여 이송 효율성이 향상되도록 한 슬러지 이송장치에 관한 것이다.Conventional Patent No. 733790 vacuum-suction and transports high-viscosity food waste and sediment from the sewage treatment plant on the pipeline, but pumping means is installed in parallel to allow the discharge to occur while one side is discharged so that the sludge is continuously discharged from the pipeline. It relates to a sludge transfer device that can be transferred, and is quickly switched using a separate switching valve when opening and closing the suction and discharge pipes, thereby improving the transfer efficiency by increasing the suction and discharge volume as much as possible.

그러나 종래의 이송장치는 흡입절환밸브 및 배출절환밸브가 이중으로 구비되고, 각 절환밸브에는 두개의 흡입관 및 두개의 배출관이 이중으로 구비되어야 하므로 구조가 복잡한 단점이 있었다.However, the conventional transfer device has a drawback in that the suction switching valve and the discharge switching valve are provided in duplicate, and each switching valve must be provided with two suction pipes and two discharge pipes, so that the structure is complicated.

이를 해결하기 위하여 종래 특허 제1862601호는 실린더를 병렬로 설치하고 각 실린더와 한쌍의 스크류컨베이어 사이에 삼방밸브관을 결합한 피스톤펌프를 제안한 바 있다. 이는 호퍼에서 공급되는 슬러지가 스크류컨베이어를 통하여 각 실린더에 교대로 압송되면 삼방밸브관에서 배출관을 통하여 원하는 장소에 이송되는 구조로써, 이때 실린더의 작동중에 피스톤의 마모를 방지하기 위하여 구리스를 공급하여 피스톤의 수명을 늘린 것이다.To solve this, the conventional patent No. 1862601 proposed a piston pump in which cylinders are installed in parallel and a three-way valve tube is coupled between each cylinder and a pair of screw conveyors. This is a structure in which the sludge supplied from the hopper is alternately pushed to each cylinder through a screw conveyor, and is transferred to a desired place through a discharge pipe from a three-way valve pipe. At this time, the piston is supplied with grease to prevent abrasion of the piston during operation of the cylinder. It will increase the lifespan.

그러나 종래 특허는 호퍼에서 공급되는 슬러지가 별도 압축수단 없이 적층된 무게로 상기 스크류컨베이어에 공급되므로 해당 실린더에 압송되는 과정에서 실린더의 흡입속도보다 빠르게 압송될 경우 상기 호퍼로 슬러지가 역류되기 때문에 실린더에 슬러지를 압축하여 보낼 수 없는 단점이 있었다.However, in the conventional patent, since the sludge supplied from the hopper is supplied to the screw conveyor with a stacked weight without a separate compression means, when the pressure is faster than the suction speed of the cylinder in the process of being pressed against the cylinder, the sludge flows back into the cylinder. There was a drawback that sludge could not be compressed.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 호퍼에서 공급되는 슬러지가 스크류컨베이어를 타고 실린더로 압송되는 과정에서 압축된 슬러지가 호퍼 쪽으로 역류되지 않도록 상기 스크류컨베이어와 호퍼의 사이를 간헐적으로 개폐하는 수단을 마련함으로써, 실린더에서 호퍼 쪽으로 슬러지의 역류가 방지되므로 슬러지 이송효율을 높일 수 있는 슬러지 이송용 펌프장치를 제공함에 있다.The present invention was developed in consideration of the conventional problems, and the object of the present invention is to prevent the compressed sludge from flowing back toward the hopper while the sludge supplied from the hopper is pushed to the cylinder through a screw conveyor. By providing a means for intermittently opening and closing, it is to provide a pump device for sludge transfer, which can increase the efficiency of sludge transfer because the back flow of sludge from the cylinder to the hopper is prevented.

이를 위하여 본 발명 한 실시예는 서로 떨어진 한쌍의 스크류컨베이어가 내장된 스크류하우징의 개방된 상부에 슬러지를 투입하는 호퍼가 구비되고, 상기 각 스크류컨베이어에는 삼방밸브관을 통하여 연결되는 유압식 실린더가 일렬로 구비되어서 상기 각 스크류컨베이어의 회전시 슬러지가 각 삼방밸브관을 통하여 해당 실린더로 유입된 뒤 상기 삼방밸브관에 수직으로 연결된 배출관을 타고 이송되도록 한 슬러지 이송용 펌프장치에 있어서, 상기 각 스크류컨베이어를 개별적으로 감싸는 중공상의 회전관 한쌍이 상기 스크류하우징에 회전 가능하게 구비되고; 상기 각 회전관에는 상기 해당 스크류컨베이어와 호퍼를 연결하는 개방부가 형성되어서 슬러지가 상기 각 스크류컨베이어에 채워지도록 해주고, 상기 각 스크류컨베이어의 회전으로 해당 실린더에 슬러지가 채워지는 과정에서 가득 채워지기 직전 상기 회전관의 회전으로 상기 호퍼와 상기 스크류컨베이어가 차단되어 슬러지의 역류가 방지되도록 한 특징이 있다.To this end, an embodiment of the present invention is provided with a hopper for injecting sludge into an open upper part of a screw housing in which a pair of screw conveyors are separated from each other, and each of the screw conveyors is lined with a hydraulic cylinder connected through a three-way valve tube. In the pump device for sludge transfer, the sludge is transported through a discharge pipe vertically connected to the three-way valve pipe after sludge flows into the corresponding cylinder through each three-way valve pipe when the screw conveyor is rotated. A pair of hollow rotating tubes wrapped individually are rotatably provided on the screw housing; Each rotating tube is formed with an opening for connecting the corresponding screw conveyor and the hopper so that the sludge is filled in each screw conveyor, and immediately before being filled in the process in which the sludge is filled in the cylinder by the rotation of each screw conveyor. It is characterized in that the hopper and the screw conveyor are blocked by rotation of the rotating tube to prevent back flow of sludge.

본 발명에 따르면 스크류컨베이어와 호퍼 사이에 간헐적으로 개폐되는 수단이 구비되는데, 상기 개폐수단은 윗면은 개방되고 밑면은 막힌 회전관으로 구성되어 상기 스크류컨베이어를 감싼 상태로 회전되면서 스크류컨베이어와 호퍼를 개폐시킨다. 실린더에 슬러지가 2/3이상 채워지면 압축력이 걸리면서 슬러지가 잘 투입되지 않고 역류현상이 발생되는데, 이 때문에 실린더에 슬러지를 가득 채우기 어렵게 된다. 본 발명 한 실시예는 압축력이 걸리는 시점에서 개폐수단으로 스크류컨베이어와 호퍼를 차단하여 스크류컨베이어가 밀폐상태에 놓이므로 슬러지를 압축하여 실린더에 투입할 수 있게된다.According to the present invention, there is provided a means for intermittently opening and closing between the screw conveyor and the hopper, wherein the opening and closing means is composed of a rotating tube with a top surface open and a bottom surface being closed while the screw conveyor is rotated to open and close the screw conveyor and the hopper. Order. When the cylinder is filled with more than 2/3 of the sludge, compression force is applied and sludge is not well input and a backflow occurs, which makes it difficult to fill the cylinder with sludge. In one embodiment of the present invention, since the screw conveyor and the hopper are blocked by the opening and closing means at the time when the compressive force is applied, the screw conveyor is placed in a closed state so that the sludge can be compressed and injected into the cylinder.

따라서 슬러지가 호퍼 쪽으로 역류되지 않고 실린더에 가득 채워지므로 연속으로 이송되어 이송효율이 향상되는 이점이 있다.Therefore, since the sludge is not backflowed toward the hopper and is filled in the cylinder, it is continuously transferred and has an advantage of improving the transfer efficiency.

도 1 내지 도 5에서 본 발명 한 실시예의 펌프장치는 서로 떨어진 한쌍의 스크류컨베이어(11)가 내장된 스크류하우징(10)이 구비되고, 상기 스크류하우징(10)의 개방된 상부에는 슬러지가 투입되는 호퍼(12)가 구비된다. 그리고 상기 각 스크류컨베이어(11)와 나란하게 한쌍의 삼방밸브관(20) 및 한쌍의 실린더(30)가 일렬로 구비되고, 상기 각 실린더(30)는 내부의 피스톤을 유압으로 작동시키는 유압발생부(31)구 구비된다.The pump device of one embodiment of the present invention in FIGS. 1 to 5 is provided with a screw housing 10 having a pair of screw conveyors 11 separated from each other, and sludge is introduced into the open top of the screw housing 10 The hopper 12 is provided. In addition, a pair of three-way valve tubes 20 and a pair of cylinders 30 are provided in line with each of the screw conveyors 11, and each of the cylinders 30 is a hydraulic generating unit that hydraulically operates an internal piston. (31) phrase is provided.

상기 삼방밸브관(20)은 수직의 배출관(23)이 상부에 연결되고, 상기 스크류컨베이어(11)와 실린더(30)를 연결하는 흡입체크밸브판(21) 및 상기 배출관(23)과 실린더(30)를 연결하는 배출체크밸브판(22)이 내장된다. 그리고 상기 각 스크류컨베이어(11)와 호퍼(12)를 간헐적으로 연결하는 개폐수단이 구비된다.The three-way valve pipe 20 has a vertical discharge pipe 23 connected to the upper portion, and a suction check valve plate 21 connecting the screw conveyor 11 and the cylinder 30, and the discharge pipe 23 and the cylinder ( 30) is connected to the discharge check valve plate (22). And the opening and closing means for intermittently connecting each of the screw conveyor 11 and the hopper 12 is provided.

상기 개폐수단은 스크류컨베이어(11)의 회전으로 슬러지가 실린더(30)로 압송되는 과정에서 역류되는 것을 막는데, 슬러지가 실린더(30)에 2/3 이상 채워진 상태에서 최대로 채워지기 전에 압축력이 걸리면서 스크류컨베이어(11)에서 정체되거나 또는 위쪽의 호퍼(12) 쪽으로 역류되는 현상을 막는다.The opening/closing means prevents the sludge from being reversed in the process of being pushed to the cylinder 30 by the rotation of the screw conveyor 11, and the compression force before the sludge is filled to the cylinder 30 for 2/3 or more is maximized. It prevents the phenomenon of stagnation in the screw conveyor 11 or reverse flow toward the upper hopper 12 while being caught.

이를 위하여 상기 개폐수단으로 상기 스크류컨베이어(11)를 감싸는 원통형의 회전관(40)이 스크류하우징(10)에 내장된다. 상기 회전관(40)은 스크류컨베이어(11)의 외주연을 따라 동심으로 회전되게 상기 스크류하우징(10)의 내벽에 마련된 가이드레일(45)을 타고 회전되며, 상기 회전관(40)은 호퍼(12)와 스크류컨베이어(11)를 연결하는 개방부(41)가 회전관(40)의 절반 정도인 반원 크기로 형성되고, 상기 스크류하우징(10)과 접하는 끝단은 외주면에 외접기어 형태의 종동기어(42)가 구비되며, 상기 종동기어(42)와 치합되는 구동기어(43)는 상기 스크류하우징(10) 외부의 모터(44)와 연결된다.To this end, a cylindrical rotating tube 40 surrounding the screw conveyor 11 with the opening/closing means is built in the screw housing 10. The rotating tube 40 is rotated on the guide rail 45 provided on the inner wall of the screw housing 10 to be rotated concentrically along the outer periphery of the screw conveyor 11, and the rotating tube 40 is a hopper ( 12) The opening 41 connecting the screw conveyor 11 is formed in a semicircle size that is about half of the rotating tube 40, and the end contacting the screw housing 10 is a driven gear in the form of an external gear on the outer circumferential surface. (42) is provided, and the driven gear (43) engaged with the driven gear (42) is connected to a motor (44) outside the screw housing (10).

미설명부호 32는 각 실린더(30)의 피스톤 작동으로 발생되는 마찰열을 줄여주는 냉각수가 공급되는 냉각수튜브이다.Reference numeral 32 is a cooling water tube that supplies cooling water to reduce frictional heat generated by the piston operation of each cylinder 30.

이처럼 구성된 본 발명 한 실시예는 한쪽 스크류컨베이어(11)가 호퍼(12)와 차단된 상태로 회전되는 동안 반대쪽의 스크류컨베이어(11)는 정지상태로 호퍼(12)와 연결되어 슬러지가 공급된다.In one embodiment of the present invention configured as described above, while one screw conveyor 11 is rotated in a blocked state with the hopper 12, the opposite screw conveyor 11 is connected to the hopper 12 in a stopped state to supply sludge.

초기상태에서 양쪽 스크류컨베이어(11)의 회전관(40)은 개방부(41)가 호퍼(12) 쪽으로 놓여서 호퍼(12)의 슬러지가 각 스크류컨베이어(11)로 투입된다. 이후 한쪽 스크류컨베이어(11)가 회전되면 슬러지가 대응되는 삼방밸브관(20)의 흡입체크밸브판(21)을 밀고 실린더(30)에 투입되며 이때 실린더(30)는 유압발생부(31)의 작동으로 피스톤이 후진되면서 투입되는 슬러지를 흡입한다. 슬러지가 상기 실린더(30)에 2/3 이상 채워지는 시점에서 압축력이 발생 되려 할 때 회전관(40)이 모터(44)의 작동으로 회전되어 개방부(41)가 호퍼(12)의 반대쪽에 놓이면 회전관(40)에 의해 호퍼(12)와 회전중인 스크류컨베이어(11)는 차단된다. 이때 스크류컨베이어(11)에 남아 있던 잔류 슬러지는 실린더(30)로 압송되는데, 회전관(40)에 의해 스크류컨베이어(11)의 상부가 닫힌 상태이므로 슬러지는 호퍼(12) 쪽으로 역류되지 않고 실린더(30)에 압축된 상태로 가득 채워진다.In the initial state, the rotating pipe 40 of both screw conveyors 11 has an open portion 41 placed toward the hopper 12 so that the sludge of the hopper 12 is introduced into each screw conveyor 11. Subsequently, when one screw conveyor 11 is rotated, the suction check valve plate 21 of the three-way valve pipe 20 corresponding to the sludge is pushed into the cylinder 30, where the cylinder 30 is the hydraulic generating unit 31. As the piston retracts by operation, the sludge that is injected is sucked. When the sludge is about 2/3 or more filled in the cylinder 30, when the compression force is about to be generated, the rotating pipe 40 is rotated by the operation of the motor 44, so that the opening 41 is on the other side of the hopper 12. When placed, the hopper 12 and the rotating screw conveyor 11 are blocked by the rotating tube 40. At this time, the residual sludge remaining in the screw conveyor 11 is pushed to the cylinder 30. Since the upper portion of the screw conveyor 11 is closed by the rotating pipe 40, the sludge is not backflowed toward the hopper 12, and the cylinder ( 30) is filled with a compressed state.

이후 유압발생부(31)가 반대로 작동되어 피스톤이 전진될 때 해당 스크류컨베이어(11)는 정지되고, 흡입체크밸브판(21)은 닫히게 되며, 배출체크밸브판(22)이 개방되면서 실린더(30)에 채워진 슬러지가 배출관(23)으로 압송된다. 그리고 이와 동시에 반대쪽에서 대기중이던 다른 스크류컨베이어(11)가 상기와 같은 방법으로 회전되어 슬러지를 해당 실린더(30)에 압송하는데, 2/3 이상 채워지는 시점에서 회전관(40)의 회전으로 개방부(41)가 호퍼(12)의 반대쪽에 놓이면서 스크류컨베이어(11)가 밀폐되므로 슬러지는 역류되지 않고 실린더(30)에 가득 채워진 뒤 배출관(23)으로 배출되는 과정이 연속적으로 반복된다.Thereafter, when the hydraulic generating unit 31 is operated in reverse and the piston is advanced, the corresponding screw conveyor 11 is stopped, the suction check valve plate 21 is closed, and the discharge check valve plate 22 is opened while the cylinder 30 ) Is filled with sludge is discharged to the discharge pipe (23). And at the same time, the other screw conveyor 11, which was in the air on the other side, is rotated in the same way as above to feed the sludge to the corresponding cylinder 30. Since the screw conveyor 11 is sealed while the 41 is placed on the opposite side of the hopper 12, the process in which the sludge is discharged into the discharge pipe 23 after being filled in the cylinder 30 without reflux is continuously repeated.
