Description
본 고안은 예로 공작기계의 절삭유 탱크에 비중이 다른 유체가 혼입되어 있을 때 이의 분리를 효율적을 할 수 있도록 한 절삭유 탱크의 유수분리장치에 관한 것이다.The present invention relates to an oil-water separation device of a cutting oil tank, for example, to efficiently separate a fluid having a different specific gravity from a cutting oil tank of a machine tool.
일반적으로 공작기계의 경우 절삭유가 사용되어 있고, 이송계에 안내면 윤활을 위한 윤활유가 사용되어 진다. 서로 다른 성질의 이 두 유체는 기계구조상 기계사용시 혼합되어져 절삭유 탱크로 회수되어 지고 이때, 윤활유는 절삭유를 쉽게 오염시키게 된다.In general, in the case of machine tools, cutting oil is used, and lubricating oil for lubricating guide surfaces is used in the feed system. These two fluids of different properties are mixed in the machine construction and returned to the coolant tank, whereby the lubricant can easily contaminate the coolant.
이의 분리를 위하여 도 1,2에서와 같이 유수분리기(10)를 절삭유 탱크에 장착하여 유수분리모터(M)를 회전시키면 유수분리기 양끝단에 장착되어 지는 구동측 풀리(11) 및 차동풀리(12)를 통하여 유수분리벨트(13)를 회전시키게 된다.For this separation, as shown in FIGS. 1 and 2, the oil-water separator 10 is mounted on the cutting oil tank and the oil-water separation motor M is rotated so that the driving side pulley 11 and the differential pulley 12 are mounted at both ends of the oil-water separator. Rotate the oil and water separation belt 13 through).
이때 유수분리벨브(13)의 한쪽끝(차동풀리측)은 절삭유 탱크(14)에 잠겨있으며 유수분리벨트(13)의 회전에 따라 윤활유의 점성으로 인하여 윤활유가 유수분리벨브(13)에 묻어서 절삭유 탱크(14) 밖으로 상승하게 된다.At this time, one end (differential pulley side) of the oil-water separation valve 13 is locked to the cutting oil tank 14, and lubricating oil is buried in the oil-water separation valve 13 due to the viscosity of the lubricant as the oil-water separation belt 13 rotates. It rises out of the tank 14.
유수분리벨트(13)에 묻어있는 윤활유는 회전 반대편에 설치되어 있는 오일안내판(15)의 날끝에 걸러지게 되어 보조탱크(16)로 모아지게 된다.Lubricating oil buried in the oil and water separation belt 13 is filtered by the blade tip of the oil guide plate 15 installed on the opposite side of the oil separation belt 13 to be collected in the auxiliary tank 16.
보조탱크(16)에 모아지는 윤활유는 작업자 또는 자동 드레인밸브 등에 의하여 처리되게 되어 있다.Lubricating oil collected in the auxiliary tank 16 is processed by an operator or an automatic drain valve.
그러나 유수분리벨브(13)에는 윤활유뿐만 아니라 절삭유도 함께 묻어 나오기 때문에 보조탱크(16)에 채워지는 유체는 윤활유 및 절삭유가 모두 채워지게 되어 절삭유의 낭비가 심해지고 보조탱크(16)를 수시로 비워야 하는 번거로움이 있다.However, since the oil-separation valve 13 buryes not only lubricating oil but also cutting oil, the fluid filled in the auxiliary tank 16 is filled with both lubricating oil and cutting oil, which leads to severe waste of cutting oil and to empty the auxiliary tank 16 from time to time. There is a hassle.
따라서 본 고안은 상기와 같은 사정을 감안하여 안출된 것으로, 보조탱크 없이 비중을 이용하여 절삭유를 절삭유 탱크로 되돌리도록 함으로써 절삭유의 낭비를 막고 보조청소의 주기를 최소화할 수 있는 절삭유 탱크의 유수분리장치를 제공함에 그 목적이 있다.Therefore, the present invention has been devised in view of the above circumstances, and the oil-water separator of the cutting oil tank can prevent the waste of cutting oil and minimize the cycle of the auxiliary cleaning by returning the cutting oil to the cutting oil tank using specific gravity without an auxiliary tank. The purpose is to provide.
상기의 목적을 달성하기 위한 본 고안의 구체적인 수단은, 절삭유 탱크내의 하단측에 설치된 차동풀리와 그 상방에 설치된 구동풀리에 유수분리벨트를 권취시켜, 이 유수분리벨트 묻어나온 윤활유를 오일안내판에 의해 걸러서 윤활유를 분리시키도록 한 유수분리장치에 있어서, 상기 절삭유 탱크내에 이에 연통하는 리턴홀을 갖는 중간카막이를 설치하여 윤활유 저장실을 구비하고, 이 윤활유 저장실에 상기 오일안내판에서 분리되는 윤활유가 유입되도록 하여 윤활유에 포함된 절삭유를 비중차에 의해 상기 리턴홀을 통하여 절삭유 탱크내로 회수되도록 함과 동시에 상기 윤활유 저장실의 상부 일측벽에 드레인 밸브를 설치한 것을 특징으로 한다.The specific means of the present invention for achieving the above object is, by winding the oil and water separation belt on the differential pulley installed on the lower end side of the cutting oil tank and the driving pulley installed above, the oil oil separation plate In the oil-water separator for separating the lubricating oil, the oil tank is provided with an intermediate casing having a return hole in communication with the cutting oil tank, and having a lubricating oil reservoir, in which the lubricating oil separated from the oil guide plate is introduced. Thus, the cutting oil contained in the lubricating oil is recovered into the cutting oil tank through the return hole due to the specific gravity difference, and at the same time, a drain valve is installed on one upper wall of the lubricating oil storage chamber.

이하, 첨부된 도면을 참조하여 본 고안의 실시예를 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 3,4는 도 1,2와 동일한 부분은 동일부호를 사용하여 설명한다.3 and 4 will be described the same parts with the same reference numerals.
도 3,4에 도시된 바와 같이 절삭유 탱크(14)내의 하단측에 설치된 차동풀리(12)와 그 상방에 설치된 구동풀리(11)에 유수분리벨트(13)를 권취시켜, 이 유부분리벨트(13)에 묻어나온 윤활유를 오일안내판(15)에 의해 걸러서 윤활유를 분리시키도록 한 유수분리장치에 있어서, 상기 절삭유 탱크(14)내에 이에 연통하도록 하부 리턴홀(40A)을 갖는 중간카막이(40)가 설치된 윤활유 저장실(41)이 구비되어 있고, 이 윤활유 저장실(41)에 상기 오일안내판(15)에서 분리되는 윤활유가 유입되도록 하여 윤활유에 포함된 절삭유를 비중차에 의해 상기 리턴홀(40A)을 통하여 절삭유 탱크(14)내로 회수되도록 함과 동시에 상기 윤활유 저장실(41)의 상부 일측벽에 윤활유를 외부로 배출시키기 위해 드레인 밸브(50)가 설치되어 있다.As shown in Figs. 3 and 4, the oil-water separation belt 13 is wound around the differential pulley 12 provided on the lower end side of the cutting oil tank 14 and the drive pulley 11 provided above the oil-water belt. In the oil / water separator for filtering the lubricating oil buried in 13) by the oil guide plate 15 to separate the lubricating oil, the intermediate cover 40 having the lower return hole 40A to communicate with it in the cutting oil tank 14. ) Is provided with a lubricating oil storage chamber 41, the lubricating oil separated from the oil guide plate 15 is introduced into the lubricating oil storage chamber 41 so that the cutting oil contained in the lubricating oil by the specific gravity difference is returned to the return hole 40A. The drain valve 50 is installed in the cutting oil tank 14 to allow the lubricant oil to be discharged to the outside at the same time as the upper side wall of the lubricant storage chamber 41.
그리고, 상기 중간칸막이(40)의 상방에 상판(42)을 설치하여 상기 드레인밸브(50)가 닫쳐져 있을 경우 오버 플로워되는 윤활유를 상기 상판(42)과 중간칸막이(40)의 사이를 통하여 다시 절삭유 탱크(14)내로 회수되도록 되어 있다.Then, the upper plate 42 is installed above the middle partition 40 so that when the drain valve 50 is closed, lubricating oil overflowed through the upper plate 42 and the middle partition 40 again. The cutting oil tank 14 is to be recovered.
한편, 상기 중간칸막이(40)의 리턴홀(40A)에 윤활유 제거시 절삭유의 역류를 방지하기 위해 역류방지용 체크밸브를 설치할 수도 있다.On the other hand, in order to prevent the back flow of the cutting oil when the lubricant is removed in the return hole (40A) of the intermediate partition 40 may be provided with a check valve for preventing the back flow.
이와 같이 구성된 본 실시예의 작동상태를 설명한다.The operating state of this embodiment configured as described above will be described.
먼저, 유수분리모터(M)가 작동되기 전에는 절삭유탱크(14)내의 유면높이와 윤활유저장실(41)의 유면높이는 같은 상태에 있게 된다.First, the oil level in the cutting oil tank 14 and the oil level in the lubricating oil storage chamber 41 are in the same state before the oil / oil separation motor M is operated.
유수분리모터(M)를 회전시키면 유수분리기 양끝단에 장착되어 지는 구동측 풀리(11) 및 차동풀리(12)를 통하여 함께 회전되는 유수분리벨트(13)에 의해 유수분리벨트(13)의 하부에서 절작유에 포함된 윤활유의 점성으로 인하여 윤활유가 유수분리벨브(13)에 묻어서 절삭유 탱크(14) 밖으로 상승하게 된다.When the oil-separation motor (M) is rotated, the lower portion of the oil-water separation belt (13) by the oil-water separation belt (13) rotated together through the driving side pulley (11) and the differential pulley (12) mounted at both ends of the oil / water separator. Due to the viscosity of the lubricant contained in the cutting oil in the lubricating oil is buried in the oil-water separation valve 13 to rise out of the cutting oil tank (14).
상승하는 유수분리벨트(13)에 묻어있는 윤활유는 회전반대편에 설치되어 있는 오일안내판(15)의 날끝에 걸러지게 되어 윤활유저장실(41)로 수집되게 된다.Lubricating oil buried in the rising oil-water separation belt 13 is filtered by the blade tip of the oil guide plate 15 installed on the opposite side of the rotating oil to be collected in the lubricant storage chamber 41.
이때 윤활유와 절삭유의 비중차에 의해 절삭유 높이(H2)와 윤활유 높이(H1)이가 윤활유 저장실(41)에 발생하게 된다.At this time, the cutting oil height H2 and the lubricating oil height H1 are generated in the lubricating oil storage chamber 41 due to the specific gravity difference between the lubricating oil and the cutting oil.
즉, 윤활유저장실(41)의 절삭유 높이(H2)는 낮아지게 되고, 윤활유 높이(H1)는 높아지게 된다.(드레인 밸브(50)를 열지 않았을 경우)That is, the cutting oil height H2 of the lubricating oil storage chamber 41 becomes low, and the lubricating oil height H1 becomes high (when the drain valve 50 is not opened).
이때, 윤활유 저장실(41)내의 윤활유 비중(γ1), 윤활유높이(H1), 절삭유 비중(γ2), 절삭유 높이(H2), 그리고 절삭유 탱크(14)내의 절삭유 높이(H)로 가정하면 다음과 같은 식이 성립한다.In this case, it is assumed that the lubricating oil specific gravity γ 1 , the lubricating oil height H1, the cutting oil specific gravity γ 2 , the cutting oil height H2, and the cutting oil height H in the cutting oil tank 14 are as follows. Equation
H1×γ1=(H-H2)×γ2 H1 × γ 1 = (H-H2) × γ 2
이같은 상태에서 드레인 밸브(50)를 열게 되면 외부로 윤활유를 배출시킬 수 있다. 그리고 윤활유 저장실(41)에 채워진 절삭유는 리턴홀(40A)을 통하여 일부가 계속해서 절삭유탱크(14)내로 회수되게 된다.In this state, when the drain valve 50 is opened, lubricant oil can be discharged to the outside. Part of the cutting oil filled in the lubricating oil storage chamber 41 is continuously recovered into the cutting oil tank 14 through the return hole 40A.
한편, 드레인밸브(50)를 닫아놓게 되면 윤활유저장실(41)에 채워진 윤활유는 상판(42)과 중간칸막이(40)의 사이로 오버 플로워되어 절삭유 탱크(14)내로 회수되게 된다.On the other hand, when the drain valve 50 is closed, the lubricating oil filled in the lubricating oil storage chamber 41 overflows between the upper plate 42 and the intermediate partition 40 and is recovered into the cutting oil tank 14.
이같이 윤활유저장실(41)에 채워진 윤활유만 외부로 배출가능하게 됨으로써 절삭유의 불필요한 낭비를 막을 수 있고, 또 종래와 같이 보조탱크를 수시로 비워야 하는 불편함도 없게 된다.Since only the lubricating oil filled in the lubricating oil storage chamber 41 can be discharged to the outside, unnecessary waste of cutting oil can be prevented, and the inconvenience of having to empty the auxiliary tank from time to time is eliminated.
그리고 상기 윤활유 저장실(41)의 일측벽에 외부에서 이의 유면높이를 관찰하기 용이하도록 투시창을 두는 것이 바람직하다.And it is preferable to place a viewing window on one side wall of the lubricating oil storage chamber 41 so as to easily observe the oil level thereof from the outside.
상술한 바와 같이 본 고안에 의하면 유슈분리장치에서 걸러지는 윤활유에 포함된 절삭유를 절삭유 탱크로 다시 회수토록 함과 동시에 걸러진 윤활유만 배출케함으로 절삭유의 낭비를 막을 수 있고, 윤활유제거 작업주기를 최소화할 수 있는 장점이 있다.As described above, according to the present invention, the cutting oil contained in the lubricating oil filtered by the yushu separator may be recovered back to the cutting oil tank, and at the same time, only the filtered lubricating oil may be discharged to prevent waste of cutting oil and minimize the lubricating oil removal work cycle. There are advantages to it.
