Description

폐절삭유의 재사용장치{WASTE-OIL RETREAT APPARATUS}Waste cutting oil reuse device{WASTE-OIL RETREAT APPARATUS}

본 발명은 폐절삭유의 재사용장치에 관한 것으로서, 더욱 상세하게는 절삭액에 포함된 금속칩 중 비교적 부피가 큰 금속칩을 폐절삭유전처리부에서 우선적으로 걸러낸 후, 폐절삭유여과부를 통해 나머지 금속칩을 분리함으로써, 절삭유의 여과율을 향상시키고자 하는 폐절삭유의 재사용장치에 관한 것이다.The present invention relates to an apparatus for reusing waste cutting oil, and more particularly, a relatively bulky metal chip among metal chips contained in a cutting fluid is first filtered by a waste cutting oil pretreatment unit, and then the remaining metal chips through a waste cutting oil filter unit. By separating, it relates to a reuse apparatus for waste cutting oil to improve the filtration rate of the cutting oil.

일반적으로 공작물의 절삭이나 연삭 또는 정밀연마 가공라인에 사용되는 절삭유는 가공 중에 발생하는 칩을 포함하고 있기 때문에 이의 재사용을 위해서는 이물질 등을 제거한 후 순수한 절삭유만을 채집하여 재사용하게 된다.In general, cutting oil used for cutting, grinding, or precision polishing processing lines of workpieces contains chips generated during processing, so for reuse, only pure cutting oil is collected and reused after removing foreign substances.

통상, 공작기계인 CNC 장비, 머시닝센터 또는 연마기 등의 장비를 이용하여 공작물을 가공할 경우 다량의 칩(CHIP), 절삭분 및 연삭 슬러지(이하 "슬러지"라 통칭함) 등이 발생하게 되고, 이러한 절삭물의 가공시 고속가공에 따라 절삭물과 절삭공구에는 고열이 발생하게 되어 절삭공구의 사용수명을 단축하게 됨은 물론, 절삭과정에서 발생하는 슬러지는 가공과 동시에 공급되는 절삭유에 함유된 상태로 순환하는 방식으로 사용하게 된다.In general, when a workpiece is processed using equipment such as CNC equipment, a machining center or a grinder, which is a machine tool, a large amount of chips (CHIP), chips and grinding sludge (hereinafter referred to as "sludge") are generated. When processing such a cutting material, high heat is generated in the cutting material and the cutting tool due to high-speed processing, which shortens the service life of the cutting tool, and the sludge generated during the cutting process is circulated in a state contained in the cutting oil supplied at the same time as the processing. You will use it in a way that you do.

이러한 절삭유는 최초에 공급할 경우는 별 문제가 발생하지 않으나, 장시간 사용하게 되면 절삭유에 함유된 슬러지는 자중에 의해 하부로 침전되고 나머지의 절삭유만 순환시켜 재사용을 하고 있으므로, 절삭유는 순환의 과정에서 유동으로 인해 슬러지가 함유된 상태로 순환을 하게 되어 분사노즐을 막게 되는 요인으로 작용하게 된다.If such cutting oil is initially supplied, there is no problem, but if it is used for a long time, the sludge contained in the cutting oil is settled down by its own weight and only the remaining cutting oil is circulated for reuse, so the cutting oil flows in the process of circulation. As a result, it circulates in a state containing sludge and acts as a factor that blocks the injection nozzle.

또한, 이와 같이 절삭유에 함유된 슬러지가 절삭유와 함께 이동이 되므로 인해 장비에 과부하게 발생하게 되어 동력의 손실이 과도할 뿐만 아니라 가공도중 절삭유의 공급불량으로 인해 절삭물과 절삭공구에 과열이 발생하게 되어 가공의 효율성이 불량하게 되고, 한편으로는 절삭공구가 파손되거나 심하게 마모되는 등의 현상이 발생하여 상기 절삭공구의 교체에 따른 시간적인 손실은 물론, 장비의 정지로 인한 작업능률이 저하되는 문제가 있다.In addition, since the sludge contained in the cutting oil moves together with the cutting oil, the equipment is overloaded, resulting in excessive loss of power, as well as overheating of the cutting material and cutting tools due to poor supply of cutting oil during processing. As a result, the efficiency of processing becomes poor, and on the other hand, a phenomenon such as damage or severe wear of the cutting tool occurs, resulting in a loss of time due to the replacement of the cutting tool as well as a decrease in work efficiency due to the equipment stop There is.

따라서, 근래에는 이와 같은 문제점을 해소하고자 국내특허등록 제387169호, 국내특허등록 제805248호로'절삭유 여과장치'가 제안된 바 있다.Therefore, in recent years, in order to solve such a problem, a'cutting oil filtering device' has been proposed with Korean Patent Registration No. 387169 and Domestic Patent Registration No. 805248.

상기한 기술구성은 본 발명의 이해를 돕기 위한 배경기술로서, 본 발명이 속하는 기술분야에서 널리 알려진 종래기술을 의미하는 것은 아니다.The above-described technical configuration is a background technique to aid understanding of the present invention, and does not mean a conventional technique widely known in the art to which the present invention belongs.

기존의 절삭유 여과장치는 칩을 함유한 절삭유를 공급받아 필터로 낙하시키며 칩을 걸러내는데, 칩이 절삭유가 낙하되는 필터의 특정 부위에 집중 적층됨에 따라, 필터는 칩의 부분적 적층으로 인해 절삭유의 통과가 불균일하여 필터링 효율이 저하되고, 칩의 부분적 적층 위치에서 절삭유의 통과가 이뤄지지 않음에 따라 교체가 청소가 필요함으로써 자주 청소해야 하는 번거로움이 있으며, 그 청소를 위하여 절삭유 여과 장치의 작동을 정지해야 함에 따라 설비의 작동을 정지해야 함으로써 가공 효율이 극히 저하되는 문제점이 있다.Existing coolant filtration devices receive cutting oil containing chips and drop them into a filter to filter the chips. As the chips are concentrated on a specific area of the filter where the coolant falls, the filter passes the cutting oil due to the partial stacking of the chips. The filtering efficiency is degraded due to the unevenness of the chip, and as the cutting oil does not pass through at the partially stacked position of the chip, replacement is required to be cleaned, causing frequent cleaning, and the operation of the coolant filtration device must be stopped for cleaning. Accordingly, there is a problem in that the processing efficiency is extremely deteriorated by having to stop the operation of the facility.

따라서, 이를 개선할 필요성이 요청된다.Therefore, there is a need to improve this.

In this case, the filter roll 260 is naturally rotated and the filter filter 262 is released and supplied.

또는, 필터롤(260)의 롤러축(264)이 구동원에 의해 강제 회전됨으로써, 여과필터(262)가 강제 이송될 수 있다. 이 경우, 상부롤러(230)와 하부롤러(240)는 자연 회전된다.Alternatively, as the roller shaft 264 of the filter roll 260 is forcibly rotated by a driving source, the filter filter 262 may be forcibly transferred. In this case, the upper roller 230 and the lower roller 240 are rotated naturally.

한편, 축지부(270)는 폐절삭유탱크(110)의 외측에서 필터롤(260)을 회전 가능하게 거치하여 여과필터(262)를 안정적으로 공급 안내하는 역할을 한다.Meanwhile, the shaft support part 270 serves to stably supply and guide the filter filter 262 by rotatably mounting the filter roll 260 on the outside of the waste cutting oil tank 110.

상세히, 유입관(220)은 중공인 내부에 격판(225)을 구비한다. 유입관(220)은 격판(225)에 의해 축 방향을 따라 양분된다. 격판(225)에 의해 양분되어 폐절삭유가 없는 공간에 회동축(226)이 회동 가능하게 연결된다. 그리고, 회동축(226)은 플로터(227)를 구비한다. 플로터(227)는 유입관(220)의 하부에 위치하도록 회동축(226)에 연결된다. In detail, the inlet pipe 220 is provided with a diaphragm 225 inside the hollow. The inlet pipe 220 is bisected along the axial direction by the diaphragm 225. It is bisected by the diaphragm 225 and the rotation shaft 226 is rotatably connected to a space where there is no waste cutting oil. And, the rotation shaft 226 is provided with a plotter 227. The plotter 227 is connected to the rotation shaft 226 so as to be located under the inlet pipe 220.

특히, 유입관(220)의 내측에 위치된 회동축(226)에는 근접레버(228)가 유입관(220)의 일측 단부로 돌출되도록 설치되고, 근접레버(228)의 회동 구간 중 일부에 근접센서(229)가 폐절삭유탱크(110)에 고정 설치된다.In particular, the proximity lever 228 is installed on the rotation shaft 226 located inside the inlet pipe 220 so as to protrude to one end of the inlet pipe 220, and is close to a part of the rotation section of the proximity lever 228 The sensor 229 is fixedly installed in the waste cutting oil tank 110.

아울러, 여과필터(262)는 폐절삭유탱크(110)의 일측에서 가이드원판(210)과 이송부재(250) 사이로 삽입된 후 폐절삭유탱크(110)의 타측으로 인출된다. 이때, 여과필터(262)는 가이드원판(210)의 누름에 의해 하부 방향으로 볼록한 곡면을 형성한다. 물론, 이송부재(250)도 가이드원판(210)의 누름에 의해 하부 방향으로 볼록한 궤적을 이루게 된다.In addition, the filtration filter 262 is inserted between the guide disk 210 and the transfer member 250 at one side of the waste cutting oil tank 110 and is then drawn out to the other side of the waste cutting oil tank 110. At this time, the filter filter 262 forms a convex curved surface in a downward direction by pressing the guide disk 210. Of course, the transfer member 250 also forms a convex trajectory in a downward direction by pressing of the guide disk 210.

이와 같이, 여과필터(262)가 장착된 상태에서, 금속칩을 함유한 폐절삭유가 유입관(220)을 통해 폐절삭유탱크(110)로 유입되면서 여과필터(262)에 의해 금속칩이 걸러진다.In this way, while the filtration filter 262 is mounted, the metal chips are filtered by the filtration filter 262 while the waste cutting oil containing metal chips flows into the waste cutting oil tank 110 through the inlet pipe 220. .

아울러, 여과필터(262)에 금속칩이 쌓여감에 따라, 폐절삭유탱크(110) 내부에서 여과필터(262) 상부의 폐절삭유의 수위가 점차 높아지게 된다. In addition, as the metal chips accumulate in the filtration filter 262, the level of the waste cutting oil above the filtration filter 262 in the waste cutting oil tank 110 gradually increases.

폐절삭유의 수위에 따라 플로터(227)가 상승하게 되고, 플로터(227)가 고정된 회동축(226)도 함께 회전된다. 따라서, 회동축(226)에 고정 설치된 근접레버(228)가 플로터(227)와 반대방향으로 회동하게 된다. 근접레버(228)의 끝단부의 회동 궤적 상에는 근접센서(229)가 설치되어 있는데, 근접센서(229)의 정확한 설치위치는 폐절삭유가 더 이상의 수위로 상승되면 안 되는 곳이다. 즉, 더 이상 상승되면 안되는 폐절삭유의 수위에서의 플로터(227)의 위치에 의해 결정된 근접레버(228)의 위치에 근접센서(229)가 설치된다.The plotter 227 rises according to the level of the waste cutting oil, and the rotation shaft 226 to which the plotter 227 is fixed is also rotated. Accordingly, the proximity lever 228 fixedly installed on the rotation shaft 226 rotates in the opposite direction to the plotter 227. A proximity sensor 229 is installed on the rotational trajectory of the end of the proximity lever 228, and the exact installation position of the proximity sensor 229 is a place where the waste cutting oil should not rise to the water level any more. That is, the proximity sensor 229 is installed at the position of the proximity lever 228 determined by the position of the plotter 227 at the level of the waste cutting oil that should not be raised any more.

이로써, 플로터(227)의 연속적인 상향 회동에 의해, 근접레버(228)가 연속적으로 하방으로 회동하다가, 최대 폐절삭유의 수위에서 근접레버(228)가 근접센서(229)와 만나게 된다. Accordingly, the proximity lever 228 continuously rotates downward due to the continuous upward rotation of the plotter 227, and the proximity lever 228 meets the proximity sensor 229 at the maximum level of the waste cutting oil.

그리고, 축지부(270)는 필터롤(260)의 롤러축(264)이 자중에 의하여 낙하할 수 있는 가이드홈(274)이 수직으로 형성된 한 쌍의 축지판(272)을 포함하고, 가이드홈(274)의 하부에 풀림방지롤러(276)를 포함한다.In addition, the shaft support portion 270 includes a pair of shaft support plates 272 vertically formed with a guide groove 274 through which the roller shaft 264 of the filter roll 260 can fall by its own weight, and the guide groove It includes an anti-loosening roller 276 in the lower part of 274.

따라서, 필터롤(260)은 항상 아래 방향의 중력에 의하여 하부 둘레면의 여과필터(262)는 항상 풀림방지롤러(276)에 접촉된 상태로 작동하게 된다.Accordingly, the filter roll 260 always operates in a state in which the filter filter 262 on the lower circumferential surface is in contact with the loosening prevention roller 276 by gravity in a downward direction.

즉, 근접센서(229)의 제어에 의하여, 여과필터(262)가 이송되는 경우, 필터롤(260)은 피동적으로 회전하면서 여과필터(262)를 풀게 된다. 그리고, 여과필터(262)가 일정 거리 이송된 후에는 멈추게 된다. 이로써, 여과필터(262)의 임의적 풀림이 방지되어, 여과필터(262)는 항상 일정한 장력을 유지하게 되므로, 여과필터(262)의 이동이나 가이드원판(210)과 이송부재(250) 사이의 정확한 위치로 진입할 수 있게 된다.That is, under the control of the proximity sensor 229, when the filter filter 262 is transferred, the filter roll 260 is passively rotated to release the filter filter 262. And, after the filtration filter 262 is transferred a certain distance, it is stopped. As a result, arbitrary loosening of the filtration filter 262 is prevented, so that the filtration filter 262 always maintains a constant tension, the movement of the filtration filter 262 or between the guide disk 210 and the transfer member 250 You will be able to enter the location.

어퍼쉘(310)은 폐절삭유탱크(110) 또는 폐절삭유탱크(110)의 상부로 연장되는 프레임(112)에 상하 왕복 이동 가능하게 연결된다. 특히, 프레임(112)은 하나 이상의 작동부재(312)를 직선 전후진 왕복 이동 가능하게 구비하고, 어퍼쉘(310)은 작동부재(312)에 연결되어 직선 왕복 이동된다. The upper shell 310 is connected to the waste cutting oil tank 110 or the frame 112 extending to the upper portion of the waste cutting oil tank 110 so as to be reciprocally moved up and down. In particular, the frame 112 has one or more operating members 312 to be linearly reciprocated back and forth, and the upper shell 310 is connected to the operating member 312 to linearly reciprocate.

이때, 어퍼쉘(310)은 로어쉘(320) 측으로 하강하면서 형폐(型閉)가 되어 공급되는 폐절삭유와 금속칩이 외측으로 튀거나 누유되는 것을 방지한다. 아울러, 어퍼쉘(310)은 로어쉘(320) 측의 반대 방향으로 상승하면서 형개(型開)가 되어 로어쉘(320)의 내측을 청소할 수 있게 된다.At this time, the upper shell 310 is mold-closed while descending toward the lower shell 320 to prevent the supplied waste cutting oil and metal chips from splashing or leaking outward. In addition, the upper shell 310 is mold-opened while rising in a direction opposite to the lower shell 320 so that the inner side of the lower shell 320 can be cleaned.

특히, 어퍼쉘(310)은 금속칩을 포함한 폐절삭유를 공급받을 수 있도록 인렛포트(314)를 형성한다. 이때, 인렛포트(314)는 프레임(112) 또는 폐절삭유탱크(110)의 외측으로 돌출되게 연장되고, 개수 및 형상에 한정하지 않는다.In particular, the upper shell 310 forms an inlet port 314 so that waste cutting oil including metal chips can be supplied. At this time, the inlet port 314 extends to protrude to the outside of the frame 112 or the waste cutting oil tank 110, and is not limited to the number and shape.

또한, 로어쉘(320)은 어퍼쉘(310)의 하측에 구비된다. 이때, 로어쉘(320)과 어퍼쉘(310)은 상호 마주하는 방향으로 개방되게 형성된다. 특히, 로어쉘(320)은 어퍼쉘(310)에서 배출되는 폐절삭유가 퍼지거나 비산되는 것을 방지하여 여과필터(262) 측으로 유동되도록 안내하는 역할을 한다.In addition, the lower shell 320 is provided under the upper shell 310. At this time, the lower shell 320 and the upper shell 310 are formed to be open in a direction facing each other. In particular, the lower shell 320 serves to guide the flow toward the filtration filter 262 by preventing the waste cutting oil discharged from the upper shell 310 from spreading or scattering.

한편, 스프레드유닛(330)은 외부에서 어퍼쉘(310)의 인렛포트(314)로 유입되는 금속칩과 폐절삭유를 어퍼쉘(310)의 하측에 위치한 로어쉘(320)에 고르게 낙하되도록 하는 역할을 한다. 이를 통해, 로어쉘(320) 전체에 걸쳐 고르게 낙하된 폐절삭유는 안정적으로 일정하게 여과필터(262)에 대체적으로 고르게 투하된다.On the other hand, the spread unit 330 serves to evenly drop metal chips and waste cutting oil flowing into the inlet port 314 of the upper shell 310 from the outside to the lower shell 320 located under the upper shell 310 Do it. Through this, the waste cutting oil evenly dropped across the lower shell 320 is stably and uniformly dropped on the filtration filter 262 in general.

여기서, 스프레드유닛(330)은 분배라인(332) 및 메쉬망부재(334)를 포함한다.Here, the spread unit 330 includes a distribution line 332 and a mesh network member 334.

분배라인(332)은 어퍼쉘(310)의 내측에서 인렛포트(314)에 연결된 채, 어퍼쉘(310)의 내측에서 다??향으로 분기되게 형성되고, 분기되는 축 방향을 따라 토출구(333)를 설정 간격으로 유격되게 형성하여 금속칩과 폐절삭유를 여과필터(262) 측으로 넓은 범위에 걸쳐 배출 안내하는 역할을 한다. The distribution line 332 is formed to diverge from the inside of the upper shell 310 to the inlet port 314 while being connected to the inlet port 314 from the inside of the upper shell 310, and is formed to diverge in the direction of the divergence, and the discharge port 333 along the branched axial direction. ) Is formed to be spaced at set intervals to guide the discharge of metal chips and waste cutting oil to the filtration filter 262 over a wide range.

이때, 분배라인(332)은 다양한 형상으로 변형 가능하다. 아울러, 분배라인(332)은 볼팅 등 다양한 방식으로 어퍼쉘(310)의 내측에 고정된다.At this time, the distribution line 332 can be deformed into various shapes. In addition, the distribution line 332 is fixed to the inside of the upper shell 310 in various ways such as bolting.

또한, 메쉬망부재(334)는 어퍼쉘(310) 내측에서 분배라인(332)의 하측에 배치되어, 분배라인(332)에서 토출되는 금속칩과 폐절삭유를 여과필터(262)에 더욱 고르게 펼쳐지도록 낙하 유도하는 역할을 한다. 특히, 메쉬망부재(334)는 폐절삭유에 함유된 비교적 입자가 큰 금속칩을 걸러내는 역할을 한다. 물론, 메쉬망부재(334))는 메쉬홀의 크기 및 개수에 한정하지 않는다.In addition, the mesh net member 334 is disposed under the distribution line 332 inside the upper shell 310 to spread the metal chips and waste cutting oil discharged from the distribution line 332 more evenly on the filtration filter 262. It plays the role of inducing the fall. In particular, the mesh mesh member 334 serves to filter out metal chips having relatively large particles contained in the waste cutting oil. Of course, the mesh net member 334 is not limited to the size and number of mesh holes.

메쉬망부재(334)가 어퍼쉘(310)에 고정된 상태일 경우, 비교적 입자가 큰 금속칩은 메쉬망부재(334)를 통과하지 못하고 걸리게 되지만, 비교적 입자가 작은 금속칩은 메쉬망부재(334)를 통해 여과필터(262)의 특정 위치에 집중 적층될 수도 있다.When the mesh net member 334 is fixed to the upper shell 310, the metal chips having relatively large particles cannot pass through the mesh net member 334 and are caught, but the metal chips having relatively small particles are applied to the mesh net member ( It may be concentrated and stacked at a specific position of the filter filter 262 through 334.

이를 방지하기 위해, 어퍼쉘(310)은 메쉬망부재(334)를 진동시켜 흔들기 위해 진동자(318)를 구비할 수 있다. 어퍼쉘(310)은 내측에 지지턱(316)을 형성하고, 지지턱(316)은 복수 개의 진동자(318)를 고정 지지하며, 메쉬망부재(334)는 진동자(318)에 놓이게 된다.To prevent this, the upper shell 310 may be provided with a vibrator 318 to vibrate and shake the mesh net member 334. The upper shell 310 forms a support jaw 316 on the inside, the support jaw 316 fixedly supports a plurality of vibrators 318, and the mesh net member 334 is placed on the vibrator 318.

그래서, 메쉬망부재(334)가 진동자(318)의 진동으로 인해 흔들림이 발생됨으로써, 금속칩이 여과필터(262)에 고르게 퍼지면서 낙하할 수 있게 된다.Thus, the mesh mesh member 334 is shaken due to the vibration of the vibrator 318, so that the metal chips can be evenly spread and dropped on the filter filter 262.

아울러, 분배라인(332) 또는 어퍼쉘(310)은, 토출구(333)에서 토출되는 금속칩과 폐절삭유가 메쉬망부재(334) 측으로 고르게 뿌려지도록, 안내판(336)을 구비할 수 있다.In addition, the distribution line 332 or the upper shell 310 may be provided with a guide plate 336 so that the metal chips and waste cutting oil discharged from the discharge port 333 are evenly distributed toward the mesh network member 334.

즉, 안내판(336)은 폐절삭유가 여과필터(262)의 가장자리 측으로 뿌려지지 않도록 함으로써 금속칩이 여과필터(262)의 가장자리 부위를 따라 집중 적층되는 것을 방지하는 역할을 한다. That is, the guide plate 336 serves to prevent the metal chips from being concentrated along the edge of the filter filter 262 by preventing the waste cutting oil from being sprayed to the edge of the filter filter 262.

한편, 폐절삭유희석부(400)는 폐절삭유수위센서(405), 농도검출기(410), 희석액탱크(420), 여과절삭유공급탱크(430) 및 제어부를 포함한다.Meanwhile, the waste cutting oil dilution unit 400 includes a waste cutting oil level sensor 405, a concentration detector 410, a dilution tank 420, a filtered cutting oil supply tank 430, and a control unit.

Plays a role.

아울러, 제어부는 폐절삭유탱크(110)의 폐절삭유의 농도를 조정하도록 폐절삭유탱크(110)에 저장된 폐절삭유의 특정시점 또는 실시간으로 검출되는 농도에 의해 희석액을 폐절삭유에 공급 제어하는 역할을 한다.In addition, the control unit serves to supply and control the diluted solution to the waste cutting oil according to the concentration detected in real time or at a specific time of the waste cutting oil stored in the waste cutting oil tank 110 so as to adjust the concentration of the waste cutting oil in the waste cutting oil tank 110. .

상세히, 폐절삭유수위센서(405)는 폐절삭유탱크(110) 내부의 최고치 수위와 최저치 수위를 검출하도록 서로 다른 높이에 배치되는 복수 개 구비될 수 있으나, 폐절삭유탱크(110) 내부의 수위를 실시간으로 검출할 수 있도록 검침봉 형태로 구비되는 것으로 한다. In detail, the waste cutting oil level sensor 405 may be provided with a plurality of disposed at different heights to detect the maximum and minimum water levels inside the waste cutting oil tank 110, but the water level inside the waste cutting oil tank 110 is measured in real time. It is assumed to be provided in the form of a meter needle so that it can be detected by using.

특히, 가공기(10)로부터 흘러나오는 폐절삭유의 농도는 최초 공급되는 절삭유의 농도와 상이해 질 수 있다. 즉, 순환되는 폐절삭유는 최초 공급되는 절삭유보다 농도가 짙게 되고 점도가 높아지게 된다. In particular, the concentration of the waste cutting oil flowing from the processing machine 10 may be different from the concentration of the initially supplied cutting oil. That is, the circulating waste cutting oil has a higher concentration and a higher viscosity than the first supplied cutting oil.

희석액탱크(420)는 폐절삭유를 저장하는 폐절삭유탱크(110)에 희석액을 공급하는데, 희석액은 공업수나 수돗물 등 다양하게 적용 가능하다. 희석액은 보충관(422)을 연장하고, 보충관(422)은 폐절삭유탱크(110) 내부로 삽입된다. 아울러, 보충관(422)은 가동펌프(424)를 구비한다. The dilution liquid tank 420 supplies a dilution liquid to the waste cutting oil tank 110 that stores the waste cutting oil, and the dilution liquid can be variously applied, such as industrial water or tap water. The diluent extends the supplement pipe 422, and the supplement pipe 422 is inserted into the waste cutting oil tank 110. In addition, the supplement pipe 422 is provided with a movable pump 424.

그래서, 가동펌프(424)가 가동시, 희석액탱크(420) 내부의 희석액은 보충관(422)을 통해 폐절삭유탱크(110) 내부로 설정량만큼 공급된다.Thus, when the movable pump 424 is operated, the dilution liquid in the dilution liquid tank 420 is supplied to the inside of the waste cutting oil tank 110 by a set amount through the supplementary pipe 422.

한편, 제어부는 농도검출기(410)를 통해 특정시점 또는 실시간으로 폐절삭유탱크(110)에 저장된 폐절삭유가 설정치를 벗어난(짙은) 농도임을 검출시, 해당 절삭유가 설정범위의 농도가 될 때까지, 가동펌프(424)를 가동시켜 희석액탱크(420)로부터 희석액을 폐절삭유탱크(110)로 공급하는 역할을 한다.On the other hand, when the control unit detects that the concentration of the waste cutting oil stored in the waste cutting oil tank 110 is out of the set value (dark) through the concentration detector 410 at a specific time or in real time, until the corresponding cutting oil reaches the concentration of the set range, The movable pump 424 is operated to supply the dilution liquid from the dilution liquid tank 420 to the waste cutting oil tank 110.

이때, 농도검출기(410)가 폐절삭유탱크(110)에 저장된 폐절삭유의 농도가 높은 상태임을 검출시, 제어부는 자체 연산을 통해 필요한 희석액의 양을 산출함으로써 가동펌프(424)의 가동시간을 제어하게 된다.At this time, when the concentration detector 410 detects that the concentration of the waste cutting oil stored in the waste cutting oil tank 110 is in a high state, the control unit controls the operation time of the movable pump 424 by calculating the required amount of diluent through its own calculation. It is done.

특히, 가동펌프(424)의 가동으로 인해 희석액이 폐절삭유탱크(110)로 공급될 경우, 제어부는 폐절삭유탱크(110) 내부에 구비된 교반기가 설정시간만큼 가동되도록 제어할 수 있다. 교반기는 폐절삭유와 희석액의 혼합성을 향상시키는 역할을 한다. In particular, when the dilution liquid is supplied to the waste cutting oil tank 110 due to the operation of the movable pump 424, the control unit may control the agitator provided in the waste cutting oil tank 110 to operate for a set time. The stirrer serves to improve the mixing properties of the waste cutting oil and the diluent.

한편, 희석액과 혼합되어 농도가 희석된 폐절삭유는 여과절삭유공급탱크(430)로 공급된다. 즉, 폐절삭유탱크(110)와 여과절삭유공급탱크(430)는 순환관(432)으로 연결된다. 그리고, 순환관(432)은 순환펌프(434)를 구비한다. 순환펌프(434)는 폐절삭유탱크(110)에 저장된 폐절삭유를 여과절삭유공급탱크(430)로 강제 이송시키는 역할을 한다.Meanwhile, the waste cutting oil mixed with the diluent and diluted in concentration is supplied to the filtered cutting oil supply tank 430. That is, the waste cutting oil tank 110 and the filtered cutting oil supply tank 430 are connected by a circulation pipe 432. And, the circulation pipe 432 is provided with a circulation pump 434. The circulation pump 434 serves to forcibly transfer the waste cutting oil stored in the waste cutting oil tank 110 to the filtered cutting oil supply tank 430.

여과절삭유공급탱크(430)와 폐절삭유탱크(110)는 하나의 하우징 내부를 구획하여 배치될 수도 있다.The filtered cutting oil supply tank 430 and the waste cutting oil tank 110 may be arranged by dividing the inside of one housing.

특히, 걸름망(436)이 순환관(432)에 구비될 수 있다. 걸름망(436)은 순환관(432)으로 이송되는 폐절삭유로부터 금속칩 등 이물질을 걸러내는 역할을 한다. 물론, 걸름망(436)은 교체 또는 세척이 가능하도록 순환관(432)에 분리 가능하게 구비된다.In particular, a filter net 436 may be provided in the circulation pipe 432. The filter net 436 serves to filter foreign substances such as metal chips from the waste cutting oil transferred to the circulation pipe 432. Of course, the filter net 436 is detachably provided in the circulation pipe 432 to enable replacement or washing.

이때, 여과절삭유공급탱크(430)는 필요시 절삭유가 공급되고, 폐절삭유탱크(110)로부터 이송되어 온 폐절삭유를 저장하게 된다. 그리고, 여과절삭유공급탱크(430)에 저장된 폐절삭유 또는 절삭유와 폐절삭유(이하, '폐절삭유'라고 함)는 가공기(10)에 공급된다.At this time, the filtered cutting oil supply tank 430 is supplied with cutting oil when necessary, and stores the waste cutting oil transferred from the waste cutting oil tank 110. In addition, the waste cutting oil or cutting oil and waste cutting oil (hereinafter referred to as'waste cutting oil') stored in the filtered cutting oil supply tank 430 are supplied to the processing machine 10.

즉, 여과절삭유공급탱크(430)는 공급관(438)을 연장하고, 공급관(438)은 공급펌프(439)를 구비한다. 이때, 공급관(438)은 가장자리가 가공기(10)의 절삭유 공급 위치에 배치된다. 그래서, 가공기(10)가 작동시, 이에 연동되어 또는 수동 조작에 의해, 공급펌프(439)는 여과절삭유공급탱크(430)에 저장된 폐절삭유를 가공기(10) 측으로 펌핑한다.That is, the filtered cutting oil supply tank 430 extends the supply pipe 438, and the supply pipe 438 includes a supply pump 439. At this time, the supply pipe 438 is disposed at the edge of the cutting oil supply position of the processing machine 10. Thus, when the processing machine 10 is operated, the supply pump 439 pumps the waste cutting oil stored in the filtered cutting oil supply tank 430 to the processing machine 10 side by interlocking with it or by manual operation.

아울러, 여과절삭유공급탱크(430)는 수위감지센서(437)를 구비한다. In addition, the filtered cutting oil supply tank 430 is provided with a water level sensor 437.

이때, 수위감지센서(437)는 여과절삭유공급탱크(430) 내부의 최고치 수위와 최저치 수위를 검출하도록 서로 다른 높이에 배치되는 복수 개 구비될 수 있으나, 여과절삭유공급탱크(430) 내부의 수위를 실시간으로 검출할 수 있도록 검침봉 형태로 구비되는 것으로 한다. At this time, the water level detection sensor 437 may be provided with a plurality of disposed at different heights to detect the maximum and minimum water levels inside the filtered cutting oil supply tank 430, but the water level inside the filtered cutting oil supply tank 430 It is assumed to be provided in the form of a meter needle so that it can be detected in real time.

여과절삭유공급탱크(430)에 저장된 폐절삭유가 설정 수위 이하가 될 경우, 순환펌프(434)가 가동됨으로써, 폐절삭유탱크(110)에 희석된 상태로 저장된 폐절삭유가 여과절삭유공급탱크(430) 측으로 이동된다. 여과절삭유공급탱크(430)의 폐절삭유의 수위가 최대 설정치가 될 경우, 순환펌프(434)는 가동 정지된다.When the waste cutting oil stored in the filtered cutting oil supply tank 430 falls below the set level, the circulation pump 434 is operated, so that the waste cutting oil stored in a diluted state in the waste cutting oil tank 110 is filtered and the cutting oil supply tank 430 Is moved to the side. When the level of the waste cutting oil in the filtered cutting oil supply tank 430 reaches the maximum set value, the circulation pump 434 is stopped.

결과적으로, 제어부는 농도검출기(410)에 의해 폐절삭유탱크(110)에 희석액을 설정량만큼 공급하여 폐절삭유를 희석하도록 가동펌프(424)의 작동을 제어한다. 이때, 폐절삭유탱크(110) 내부에서, 희석액의 공급으로 인해 상승되는 폐절삭유의 수위가 최대 설정치에 도달하기 전에, 폐절삭유의 희석도가 정상치가 되도록, 제어부는 폐절삭유탱크(110)에서 폐절삭유의 하한치 수위를 검출한 상태에서 희석액 공급을 위해 가동펌프(424)의 작동을 제어한다.As a result, the control unit controls the operation of the movable pump 424 to dilute the waste cutting oil by supplying the dilution liquid to the waste cutting oil tank 110 by the concentration detector 410 by a set amount. At this time, inside the waste cutting oil tank 110, before the water level of the waste cutting oil that is raised due to the supply of the dilution liquid reaches the maximum set value, the control unit closes the waste cutting oil tank 110 so that the dilution degree of the waste cutting oil becomes a normal value. The operation of the movable pump 424 is controlled to supply the diluent while detecting the lower limit water level of the cutting oil.

그리고, 제어부는, 검출되는 여과절삭유공급탱크(430)의 수위가 하한치에 도달할 경우, 폐절삭유탱크(110)의 폐절삭유를 여과절삭유공급탱크(430)로 설정 수위만큼 공급하도록 공급펌프(439)의 가동을 제어한다.And, the control unit, when the detected water level of the filtered cutting oil supply tank 430 reaches the lower limit, the supply pump 439 to supply the waste cutting oil of the waste cutting oil tank 110 to the filtered cutting oil supply tank 430 by a set level. ) To control the operation.
