Description
본 고안은 오일여과장치에 관한 것으로서, 좀 더 상세히는 가공장치의 작업 중에 사용중인 오일에 대한 연속적인 세척이 가능하고, 여과성능이 우수한 새로운 구조의 오일여과장치에 관한 것이다.The present invention relates to an oil filtration device, and more particularly, to a new structure of the oil filtration device capable of continuously washing the oil in use during the operation of the processing device and having excellent filtration performance.
종래에 공작기계에서 발생하는 절삭유와 같은 오일이나 냉각수(이하에 오일이라 칭함) 등에 함유되는 금속칩이나 금속 및 비금속분말과 타르와 미생물 등을 여과하여 오일을 재사용하기 위한 오일여과장치가 사용되고 있다. 이러한 오일여과장치는 수집탱크에 수집된 폐오일을 펌프를 이용하여 여과탱크로 압송하고, 여과탱크 내에는 다단 적층된 필터부재를 구비하여 이 필터부재를 통과하면서 여과된 오일은 다시 오일수집탱크로 회수하여 재사용하고 있다. 그리고, 여과효율을 높이기 위해 여과조제로서 규조토를 필터부재의 필터층 코팅하여 사용한다.Background Art Conventionally, an oil filtration apparatus for reusing oil by filtering metal chips, metals and nonmetal powders, tars, and microorganisms contained in oils such as cutting oils generated in machine tools or cooling water (hereinafter referred to as oils), and the like are used. The oil filtration device pumps the waste oil collected in the collection tank to the filtration tank by using a pump, and includes a multi-stage stacked filter member in the filtration tank, and the oil filtered while passing through the filter member is returned to the oil collection tank. It is recovered and reused. Then, in order to increase the filtration efficiency, diatomaceous earth is used as a filtration aid coating the filter layer of the filter member.
그런데, 종래의 오일여과장치는 규조토를 필터부재에 코팅하기 위해, 규조토를 오일수집탱크에 부어서 오일과 섞은 다음, 오일과 함께 규조토를 압송하여 필터층의 표면에 코팅되는 방법을 취하였다. 이때, 필터층에 부착되기 전의 미세입자의 규조토가 불가피하게 필터층을 통과하여 여과된 오일과 함께 수집탱크로 복귀된다. 따라서, 여과된 오일 속에는 규조토가 상당량 함유되게 되고, 일정시간이 지난후에 오일이 깨긋이 여과된다 할지라도 오일수집탱크내의 절삭유에는 기투입한 규조토의 잔량이 여과된 오일과 희석되는 동안 장시간 잔존하게 되므로, 이 동안은 절삭유 등을 사용할 수 없어서 공작기계 등의 장치를 가동할 수 없는 문제점이 있었다.However, in the conventional oil filtration apparatus, in order to coat the diatomaceous earth on the filter member, the diatomaceous earth is poured into the oil collection tank and mixed with the oil, and then the diatomaceous earth is transported together with the oil to be coated on the surface of the filter layer. At this time, the diatomaceous earth of the fine particles before adhered to the filter layer is inevitably passed through the filter layer and returned to the collection tank together with the filtered oil. Therefore, a large amount of diatomaceous earth is contained in the filtered oil, and even if the oil is filtered after a certain time, the remaining amount of diatomaceous earth introduced into the cutting oil in the oil collection tank remains for a long time while being diluted with the filtered oil. During this time, there was a problem in that cutting oil or the like could not be used to operate an apparatus such as a machine tool.
또한, 종래에 필터탱크의 필터층에 쌓인 슬러지 등에 원치 않는 미생물 등이 번식하는 경우에 여과성능이 급격히 저하되는 문제점이 있었다.In addition, conventionally, when unwanted microorganisms, such as sludge accumulated in the filter layer of the filter tank breeds, there was a problem that the filtration performance is sharply reduced.
그리고, 종래의 여과장치에는 필터의 여과중이나 필터세척시에 고압이 작용하면, 필터층이 간격이 일정하게 유지되지 못하여, 금속칩 분말 등의 슬러지가 균등하게 축적되지 못하여 여과효율이 저하되는 문제점이 있었다.In addition, in the conventional filtration apparatus, when high pressure is applied during filtration or washing of the filter, the filter layer is not kept constant, and sludge, such as metal chip powder, cannot be accumulated evenly, resulting in a decrease in filtration efficiency. .
본 고안은 전술한 바와 같은 종래의 오일여과장치의 문제점에 착안하여 제안된 것으로서, 오일의 여과 중에서 공작기계의 연속적인 가동이 가능하고, 생물막이나 유기막에 의해 여과성능이 저하되지 않는 새로운 구조의 오일여과장치를 제공하고자 하는 것이다.The present invention has been proposed in view of the problems of the conventional oil filtration device as described above, and it is possible to continuously operate the machine tool during the filtration of oil, and has a new structure in which the filtration performance is not degraded by the biofilm or organic membrane. To provide an oil filtration device.

And a pump P, supplied to the filtration tank 10 through the lines L6, L7, L8, the bar V2, and the line L1, so that diatomaceous earth is supplied to the filter network 31 of the filter member 20. Coated, the oil returns to stirrer 22 via line L9 and valve V4.
(4) 오일의 여과작업을 수행한다. 이를 위해, 밸브(V7)과 밸브(V4)를 닫고, 밸브(V10)와 밸브(V2) 및 밸브(V6)를 개방한다. 그러면, 오일수집탱크(16) 내의 오일이 라인(L3)과 밸브(V10) 및 펌프(P)를 거치고, 라인(L6,L7,L8)과 밸브(V2)를 거쳐 여과탱크(10)로 주입되고 여과되고, 여과된 오일은 라인(L9)과 밸브(V6) 및 라인(L2)을 통해 오일수집탱크(16)로 복귀된다.(4) Perform oil filtration. For this purpose, the valve V7 and the valve V4 are closed, and the valve V10, the valve V2, and the valve V6 are opened. Then, the oil in the oil collection tank 16 passes through the line L3, the valve V10 and the pump P, and is injected into the filtration tank 10 via the lines L6, L7, L8 and the valve V2. And filtered, and the filtered oil is returned to the oil collection tank 16 through the line L9, the valve V6 and the line L2.
(5) 필터층의 슬러지 내에 유해한 생물막의 생장을 억제하기 위해, 오일여과 작동 중에 간헐적으로 미생물을 포획하는 규조토를 오일과 함께 약간 공급한다. 이를 위해, 상기 (4) 단계에서 밸브(V8)를 열어서 교반기(22) 내의 규조토 혼합액을 펌프(P)의 유입단으로 공급하여 오일과 함께 여과탱크(10)로 보낸다. 이에 따라, 필터층에 축적되는 금속분말 등의 슬러지 속에 규조토성분이 포함되어 미생물을 포획, 흡착함으로써, 생물막의 형성을 억제한다.(5) In order to suppress the growth of harmful biofilm in the sludge of the filter layer, diatomaceous earth which intermittently traps microorganisms during the oil filtration operation is supplied with oil. To this end, in step (4), the valve V8 is opened to supply the diatomaceous earth liquid mixture in the stirrer 22 to the inlet of the pump P, and is sent to the filtration tank 10 together with the oil. Accordingly, the diatomaceous earth component is contained in the sludge such as metal powder accumulated in the filter layer to trap and adsorb the microorganisms, thereby suppressing the formation of the biofilm.
이상에서 설명한 본 고안에 따르면, 종래의 오일여과장치와 달리, 여과작동의 초기단계에서, 교반기(22)를 통해 규조토와 오일의 혼합액을 여과탱크(10)로 주입하여 규조토를 코팅처리하여 규조토가 부착된 후에 필터부재에 오일을 통과시킴으로써, 회수되는 오일에 규조토가 잔류되지 않아서, 회수된 오일을 그대로 공작기계의 절삭유로 재사용할 수 있으므로, 공작기계의 가동을 멈추지 않고 오일여과작업을 행할 수 있는 장점이 있다. 그리고, 여과작업 중에 규조토성분을 소량식 오일과 함께 여과탱크로 공급함으로써, 축적되는 슬러지의 유해한 미생물을 포획, 흡착함으로써 미생물에 의한 생물막의 형성을 억제할 수 있다.According to the present invention described above, unlike the conventional oil filtration device, in the initial stage of the filtration operation, the diatomaceous earth is coated by injecting a mixture of diatomaceous earth and oil into the filtration tank 10 through the stirrer 22 to coat the diatomaceous earth By passing oil through the filter member after it is attached, diatomaceous earth does not remain in the recovered oil, and the recovered oil can be reused as cutting oil of the machine tool, so that oil filtration can be performed without stopping the operation of the machine tool. There is an advantage. Then, the diatomaceous earth component is supplied to the filtration tank together with a small amount of oil during the filtration operation, thereby trapping and adsorbing harmful microorganisms of the accumulated sludge, thereby suppressing the formation of the biofilm by the microorganisms.
아울러, 필터부재(20)에 스페이서(35,37)를 설치하여, 필터부재(20)간의 간격을 유지함으로써, 슬러지의 축적을 양호하게 하고, 오일배출관(14) 통로의 차단을 방지한다. 그리고, 차단판(54)을 설치하여 압축공기의 균등한 분산을 가능케 하고, 여과탱크(10)의 커버(11)를 본체의 상부에 설치함으로써, 세척시에 슬러지의 누출 등을 방지할 수 있다. 결과적으로 본 고안에 따르면, 가공장치의 작업 중에 사용중인 오일에 대한 연속적인 세척이 가능하고, 여과성능이 우수한 새로운 구조의 오일여과장치에 관한 것이다.In addition, spacers 35 and 37 are provided on the filter member 20 to maintain the distance between the filter members 20, thereby improving sludge accumulation and preventing the passage of the oil discharge pipe 14 passage. Further, by providing a blocking plate 54 to enable even distribution of compressed air, and by installing the cover 11 of the filtration tank 10 on the upper part of the main body, it is possible to prevent the sludge from leaking during cleaning. . As a result, according to the present invention, it is possible to continuously wash the oil in use during the operation of the processing apparatus, and relates to a new structure of the oil filtration device having excellent filtration performance.
