본 고안은 공작기계의 가공작업시 사용되는 절삭유(또는 냉각유)에 포함된 철분이나 찌꺼기등 각종 슬러지를 순환식으로 진공여과시켜 청결한 절삭유로서 재사용할 수 있게 함을 목적으로 안출한 절삭유의 순환식 진공클리너에 관한 것이다.The present invention is a circulating type of cutting oil devised for the purpose of circulating vacuum filtration of various sludges such as iron or debris contained in cutting oil (or cooling oil) used in the processing of machine tools to reuse them as clean cutting oil. It relates to a vacuum cleaner.

일반적으로 공작기계에 사용되는 절삭유는 가공작업후 절삭유탱크에 저장시켜 다시 사용하게 되는데 각종 공작물을 가공하게 되면 절삭유에 금속칩이나 불순물등이 포함되어 절삭유 탱크에 저장되므로, 재사용시 절삭유와 함께 급속칩 등이 가공면에 투입되어 정밀한 가공을 방해하고 거칠어지게 할 뿐 아니라 바이트 등을 손상시키는 등의 문제점이 있었다.In general, the cutting oil used in the machine tool is stored in the cutting oil tank to be used again after processing. When processing various workpieces, the cutting oil contains metal chips or impurities in the cutting oil tank, so it is stored in the cutting oil tank. There is a problem that the back is put into the processing surface to interfere with the rough machining and roughen, as well as damage the bite.

따라서, 종래에는 절삭유 탱크의 상면에 단순한 여과망을 설치하여 슬러지를 일부 여과시킨후 재사용하고 있으나 이는 구멍이 뚫린 여과망을 사용하는데 한계가 있어 여과구멍보다 작은 칩은 여과구멍을 통과하게 되므로 여과효과가 극히 적었으며, 이러한 여과효율의 불량함으로 인해 얼마 사용하지 않아 공작기계를 정지시킨 다음 새로운 절삭유로 교체해야 되므로서 작업시간을 지연시키고 경제적으로 부담을 주게되는 등의 폐단이 있었다.Therefore, in the related art, a simple filtering net is installed on the upper surface of the cutting oil tank, and the sludge is partially filtered and reused. However, this is limited in using a perforated filter net, and chips smaller than the filtration hole pass through the filtration hole. Due to this poor filtration efficiency, the machine tool must be stopped for a short time and then replaced with a new coolant, resulting in delayed working time and economic burden.

본 고안은 이와 같은 점을 감안하여 절삭유 저장탱크에 저장된 절삭유를 진공흡인시켜 여과포에 의거 정밀한 여과를 시킨다음 토출펌프로서 절삭유 저장탱크에 재투입하므로서 청결한 절삭유를 재사용할 수 있게 한 것인데, 이를 첨부도면에 의거 상술하면 다음과 같다.In view of the above, the present invention vacuum-sucks the cutting oil stored in the cutting oil storage tank to perform precise filtration based on the filter cloth, and then re-inserts it into the cutting oil storage tank as a discharge pump to reuse clean cutting oil. Based on the above, as follows.

이동용바퀴(1)를 부착한 밀폐상태의 클리너통체(2)의 여과실(3)에는 절삭유탱크(4)의 흡입관(5)이 관접되는 유입관(6)을 유출공(7)이 뚫린 선단이 취부판(8)(8')의 사이에 있도록 설치하고, 취부판(8)(8')의 내측에 근접 설치된 고정원판(9)(9')의 저부에는 로울러(10)에 의해형상으로 권회한 밴드필터(11)를 설치하여 그 내부에 유사형상의 여과조(12)를 다수개의 구멍(13)이 뚫린 호면(12')이 밴드필터(11)의 상부저면에 당접되게 설치하되 체인기어(14)의 연동으로 고정원판(9)(9')의 외면을 슬라이딩 하는 체인(15)의 스크레이퍼(16)에 의거 회전되게 하며, 여과실(3)의 하방에는 진공펌프(17)에 의거 진공상태로 되는 청정절삭유 탱크(18)를 구획설치하되 플로우 스윗치(19)와 자동수위 조절변(20)이 설치된 이송관(21)으로 여과조(12)와 연결하여 이로부터 낙하된 청정절삭유를 토출펌프(22)에 연결시킨 회수관(23)으로 절삭유탱크(4)에 토출하며 여과실(3)의 하방에 설치된 슬러지박스(24) 방향의 밴드필터(11) 내측에 유체의 흐름여부를 감지하는 플로우 스윗치(19)에 의거 작동되는 에어분사관(25)을 설치하여서 되는 구조이다.The tip of the inlet pipe 6 through which the suction pipe 5 of the cutting oil tank 4 is connected to the filtration chamber 3 of the cleaner cylinder 2 in the sealed state with the moving wheel 1 attached thereto. It is installed so as to be between these mounting plates 8 and 8 ', and the roller 10 is attached to the bottom of the stationary disks 9 and 9' which are installed near the inside of the mounting plates 8 and 8 '. A band filter 11 wound in a shape is installed, and a similar filter tank 12 therein is installed so that an arc surface 12 ′ having a plurality of holes 13 abuts on an upper bottom surface of the band filter 11. The chain gear 14 is rotated based on the scraper 16 of the chain 15 sliding the outer surface of the stationary disks 9 and 9 'by interlocking with the chain gears 14, and a vacuum pump 17 is provided below the filtration chamber 3. The clean cutting oil tank 18, which is in a vacuum state, is partitioned and connected to the filtration tank 12 by a transfer pipe 21 in which the flow switch 19 and the automatic water level control valve 20 are installed. Is flowed into the cutting oil tank (4) by the recovery pipe 23 connected to the discharge pump 22 and the flow of fluid inside the band filter (11) in the direction of the sludge box (24) installed below the filtration chamber (3). It is a structure that is provided by installing the air injection pipe 25 is operated based on the flow switch 19 for detecting the.

도면중 미설명부호 26은 청정절삭유 탱크(18)의 수위를 감지하여 토출펌프(22)의 작동을 제어하는 수위감지 스윗치이고, 27은 클리너통체(2)의 진공상태를 감지하여 진공펌프(17)의 작동을 제어하는 진공감지 스윗치이다.In the drawing, reference numeral 26 denotes a level sensing switch for controlling the operation of the discharge pump 22 by sensing the level of the clean cutting oil tank 18, and 27 is a vacuum pump 17 by sensing the vacuum state of the cleaner cylinder 2. This is a vacuum sensing switch that controls the operation of).

이와 같이된 본 고안은 공작기계에 고정식이나 이송식으로 설치하여 한번 사용된 후 절삭유탱크(4)에 회수된 금속칩이 침전된 절삭유를 진공으로 흡인시켜 여과하게 되는 것으로 먼저 진공펌프(17)를 작동시켜 청정절삭유 탱크(18)를 1차 진공상태로 형성하게 되면 이송관(21)으로 연결된 여과조(12)도 2차 진공상태가 되고, 이어서 다수개의 구멍(13)을 통해 여과실(3)내의 공기가 모두 흡출되어 결국 클리너통체(2) 전체가 진공상태가 되고 진공이 완료되면 진공감지 스윗치(27)가 이를 감지하여 진공펌프(17)의 작동을 제어한다.The present invention, as described above, is installed in a machine tool in a fixed or conveying manner, and then, once used, the vacuum oil is filtered by sucking the coolant in which the metal chips recovered in the coolant tank 4 are deposited by vacuum. When the clean cutting oil tank 18 is operated in the primary vacuum state, the filtration tank 12 connected to the transfer pipe 21 also becomes the secondary vacuum state, and then the filtration chamber 3 through the plurality of holes 13. After all the air in the air is aspirated out, the entire vacuum cleaner 2 becomes a vacuum state, and when the vacuum is completed, the vacuum sensing switch 27 senses this to control the operation of the vacuum pump 17.

이상태에서 절삭유탱크(4)의 흡인관(5)을 클리너통체(2)의 유입관(6)에 관접시키고 토출펌프(22)에 회수관(23)을 연결시키면 절삭유탱크(4)내의 오염된 절삭유는 흡인관(5)을 통해 유입관(6)으로 흡인된 후 유출공(7)으로 유출되므로서 취부판(8)(8') 사이의 밴드필터(11)의 상면에 제2도와 같이 낙하되어 저유됨과 동시에 금속칩 등의 슬러지가 밴드필터(11)에 의해 걸러진 후 여과조(12)의 호면(12')에 뚫린 구멍(13)을 통해 여과조(12)에 저장되는데, 이때 밴드필터(11)와 접면된 체인(15)은 체인기어(14)에 의해 고정원판(9)(9')의 외면을 슬라이딩 하면서 무단으로 회전하되 여과조(12)의 호면(12')과 당접된 밴드필터(11)를 가압하면서 회전되므로, 체인(15)에 부착된 스크레이퍼(16)가 밴드필터(11)를 이끌고 강제 회전시키게 됨에 따라 밴드필터(11)는 체인(15)의 회전으로 서서히 회전하게 되므로서 밴드필터(11)의 상면에 저유된 오염된 절삭유는 밴드필터(11)를 통해 여과되어 여과조(12)에 낙하된다.In this state, the suction pipe 5 of the cutting oil tank 4 is brought into contact with the inflow pipe 6 of the cleaner cylinder 2, and the recovery pipe 23 is connected to the discharge pump 22. Thus, the contaminated cutting oil in the cutting oil tank 4 Is sucked into the inlet pipe (6) through the suction pipe (5) and then flows out of the outlet hole (7) and falls on the upper surface of the band filter 11 between the mounting plate (8) (8 ') as shown in FIG. At the same time, the sludge such as metal chips is filtered by the band filter 11 and then stored in the filtration tank 12 through the holes 13 bored in the arc surface 12 ′ of the filtration tank 12. The chain 15 which is in contact with and rotates without change by sliding the outer surfaces of the fixed disks 9 and 9 'by the chain gear 14, but the band filter 11 which is in contact with the arc surface 12' of the filtration tank 12. Rotating while pressing the band, the band filter 11 is rotated by the chain 15 as the scraper 16 attached to the chain 15 is forced to rotate the band filter 11 Since the Hi rotation standing contaminated low dielectric coolant to the upper surface of the band filter 11 is filtered through a band filter 11 it is falling to the filtration tank (12).

이와 같이 여과조(12)에 저유된 청정절삭유는 이송관(21)을 통해 하방의 청정절삭유 탱크(18)로 연속적으로 낙하되어 저장되고 저장된 청정절삭유는 토출펌프(22)에 의거 회수관(23)을 통해 절삭유 저장탱크(4)에 다시 토출되므로서 공작기계에 재공급된다.As such, the clean cutting oil stored in the filtration tank 12 is continuously dropped and stored in the lower clean cutting oil tank 18 through the transfer pipe 21, and the stored clean cutting oil is collected in the recovery pipe 23 based on the discharge pump 22. It is discharged again to the cutting oil storage tank 4 through the re-supplied to the machine tool.

여기서, 토출펌프(22)는 청정절삭유가 청정절삭유 저장탱크(18)에 일정수위 이상 저유될 때 수위감지 스윗치(26)의 감지로 인해 작동되며 청정절삭유를 토출하고 수위가 낮아지면 수위감지 스윗치(26)가 다시 이를 감지하여 토출펌프(22)의 작동을 정지시키므로서 토출펌프(22)의 소손을 방지하게 된다.Here, the discharge pump 22 is operated by the detection of the water level detection switch 26 when the clean cutting oil is stored in the clean cutting oil storage tank 18 above a certain level, and discharges the clean cutting oil and the water level is lowered. 26 again detects this and stops the operation of the discharge pump 22 to prevent burnout of the discharge pump 22.

한편, 시계방향으로 회전되는 밴드필터(11)에 의해 걸러진 슬러지는 체인(15)의 스크레이퍼(16)에 의거 상부로 이송되다가 최상단 로울러(10)를 벗어나면서 아래로 낙하되어 하방에 설치된 슬러지박스(24)에 모이게 된다.On the other hand, the sludge filtered by the band filter 11 rotated in the clockwise direction is transported to the upper by the scraper 16 of the chain 15, but falls down while leaving the uppermost roller 10, the sludge box installed below ( Are gathered at 24).

또한 밴드필터(11)가 수차례에 걸친 회전으로 여과를 실시하게 되면 여과포 자체에 불순물이 끼어져 여과효율이 떨어지므로 이송관(21)을 통해 청정절삭유 탱크(18)로 낙하되는 여과된 절삭유의 양이 감소하게 되는데, 이때에는 플로우 스윗치(19)가 이를 감지하여 밴드필터(11)의 내측에 설치된 에어분사관(25)을 작동시키므로서 강한 에어를 불어주게 되면 밴드필터(11)에 부착된 불순물이 떨어지게 되므로 다시 여과를 원활하게 할 수 있게 되는 것이다.In addition, when the band filter 11 performs filtration by rotating the filter several times, impurities are trapped in the filter cloth and thus the filtration efficiency decreases. Thus, the filtered cutting oil dropped to the clean cutting oil tank 18 through the transfer pipe 21 is removed. In this case, when the flow switch 19 detects this and blows strong air while operating the air spray pipe 25 installed inside the band filter 11, the flow switch 19 is attached to the band filter 11. Since impurities fall, the filtration can be smoothed again.

그리고, 본 고안에서 밴드필터(11)는 전술한 바와 같이 체인(15)의 스크레이퍼(16)에 의거 강제 회전시키지 않고 별도의 동력으로 로울러(10)를 구동시켜 자체 회전하게 할 수도 있으며 청정절삭유 탱크(18)에 설치된 이송관(21)의 자동수위 조절변(20)은 청정절삭유 탱크(18)에 청정절삭유가 일정수위에 도달하면 자동으로 차단하는 역할을 하게 된다.In the present invention, the band filter 11 may be driven by the roller 10 by a separate power without forcing rotation based on the scraper 16 of the chain 15 as described above. The automatic water level control valve 20 of the transfer pipe 21 installed at 18 serves to automatically shut off when the clean cutting oil reaches a predetermined level in the clean cutting oil tank 18.

이와 같이 본 고안은 오염된 절삭유를 진공으로 흡인시켜 여과포로된 밴드필터(11)에 의해 여과시키고 청정절삭유를 다시 토출시켜 재사용을 하게 하는 것이므로 공작기계의 정밀한 가공작업을 가능하게 하고 바이트 등을 파손시키지 아니할 뿐 아니라, 절삭유의 잦은 교체를 필요로 하지 아니하므로 매우 경제적인 등 그 효과가 매우 크다.As such, the present invention draws the contaminated cutting oil into a vacuum to filter by the band filter 11 made of filter cloth and discharges the clean cutting oil to reuse it, thus enabling precise processing of the machine tool and damaging the bite. Not only does it do it, but it does not require frequent change of coolant, so it is very economical and the effect is great.
