Description

와류를 이용한 공작기계 절삭유 정화장치{A machine tool cutting oil purifying apparatus by using vortex}Machine tool cutting oil purifying apparatus by using vortex

본 발명은 와류를 이용한 공작기계용 절삭유 정화장치에 관한 것으로, 더욱 상세하게는 공작기계(CNC 등)에서 발생하는 절삭유의 저장 탱크 바닥에 절삭 칩(Chip) 등 불순물이 침전되면서 부식/부패가 되고 절삭유(수용성 성분)가 상부에 덮인 습동유(기름성분)로 인해 산소공급을 받지 못해 부패하면서 악취가 발생하는 등 작업환경을 해치고, 산업 폐기물화되는 것을 방지하기 위하여 절삭유 공급탱크 내에 와류를 발생시켜 침전되어 있는 칩과 불순물을 부양시키고 절삭유와 혼합되어 있는 습동유 및 절삭 칩과 함께 필터링이 가능한 절삭유 정화장치로 공급하고 필터링된 절삭유를 다시 절삭유 탱크로 순환시켜 고품질의 절삭유를 공급할 수 있도록 하는 와류를 이용한 공작기계 절삭유 정화장치에 관한 것이다.
The present invention relates to a cutting oil purification device for machine tools using vortex, and more particularly, corrosion and rot due to the precipitation of impurities such as chips in the storage tank bottom of the cutting oil generated from the machine tool (CNC, etc.) The cutting oil (water-soluble component) does not receive oxygen supply due to the sliding oil (oil component) covered on the top, which causes odors due to decay and deterioration of the working environment. Vortex flow is generated in the cutting oil supply tank to prevent industrial waste. Vortex which feeds the deposited chips and impurities and supplies them to the coolant filter system which can be filtered together with the lubricating oil and cutting chips mixed with the coolant and circulates the filtered coolant back to the coolant tank to supply high quality coolant. It relates to a machine tool cutting oil purification device used.

국내에서 사용중인 공작기계(특히, CNC 선반, 머시닝센터 등)는 절삭가공시 공작물과 공구의 냉각을 위하여 다량의 절삭유(주로 수용성)를 공급하고, 기계의 마찰/이송부분에는 마모현상을 방지하기 위하여 습동유(기름)를 공급하면서 사용하며, 절삭유와 습동유는 공작물 가공시 발생하는 작은 칩, 절삭분, 이물질 (이하 "불순물"이라 칭함)등이 혼합되어 순환하면서 대부분의 불순물은 절삭유 탱크 바닥에 침전되어 부식되고 부패한다.Machine tools used in Korea (especially CNC lathes, machining centers, etc.) supply a large amount of cutting oil (mainly water soluble) to cool the workpieces and tools during cutting, and to prevent wear on the friction / transfer parts of the machine. It is used while supplying sliding oil (oil) .Cutting oil and sliding oil are circulated by mixing small chips, cutting powder, and foreign substances (hereinafter referred to as "impurity") generated during processing of the workpiece, and most impurities are stored in the bottom of the cutting oil tank. Precipitates, corrodes and decays.

또한 습동유와 절삭유가 혼합되어 순환하면서 습동유(기름)는 절삭유(수용성) 상부에 부유하면서 절삭유에 산소 공급을 차단하므로 절삭유와 불순물의 부패를 촉진한다.In addition, the sliding oil and the cutting oil are circulated while circulating, the sliding oil (oil) floats on the cutting oil (water-soluble) and blocks oxygen supply to the cutting oil, thereby promoting the corruption of cutting oil and impurities.

이러한 절삭유는 처음에는 별 문제가 발생하지 않으나, 장시간 사용하게 되면 절삭유에 함유된 불순물은 자중에 의해 탱크 바닥에 침전되지만 일부 불순물은 절삭유에 함유된 상태로 순환을 하면서 공급되어 절삭 가공면의 품질저하, 절삭공구의 수명 단축 및 절삭유 분사 노즐의 막힘 원인이 된다.This coolant does not cause any problems at first, but when used for a long time, impurities contained in the coolant settle at the bottom of the tank due to its own weight, but some impurities are supplied while circulating in the coolant to reduce the quality of the cutting surface. This can shorten the life of the cutting tool and cause clogging of the cutting oil spray nozzle.

또한 상기와 같이 절삭유에 함유된 불순물이 절삭유와 함께 이동되므로 인해 장비에 과부하가 발생되어 동력의 손실이 발생할 뿐만 아니라 가공도중 절삭유의 공급불량으로 인해 절삭물과 절삭공구에 과열이 발생하게 되어 가공의 효율성이 저하되고, 절삭공구가 파손되거나 심하게 마모되는 등의 현상이 발생되어 상기 절삭공구의 교체에 따른 시간의 손실과 장비의 정지로 인한 작업능률이 저하되는 문제점이 발생하였다.In addition, as described above, impurities contained in the cutting oil are moved together with the cutting oil, resulting in overloading of the equipment, resulting in loss of power, and overheating of the cutting and cutting tools due to the supply of the cutting oil during processing. The efficiency is lowered, the cutting tool is damaged or badly worn, such as the loss of time due to replacement of the cutting tool and the work efficiency due to the stop of the equipment has occurred.

종래의 기술로, 발명특허 제0743899호(2007. 07. 24. 등록)는 스크랩퍼식 컨베이어에 의해 침전물이 수거되고 드럼필터와 터보필터의 2단계 여과처리과정을 거쳐 청정된 수용성인 절삭유(세척액) 속에 함유된 침전물 게거 및 비수용성인 기계 윤활유, 그리스, 방청유를 분리하는 것으로서, 공작기계 절삭유 탱크의 일측에는 금속칩과 같은 침전물을 수거하는 스크랩퍼식 컨베이어가 설치되고 그 타측에는 드럼필터와 터보필터 및 다수의 비중 분리판이 경사상으로 배열 설치되고 그 전방에는 청정 절삭유 수집실(배출실) 및 폐유 수집실을 형성하여 수용성인 절삭유 속에 함유된 비수용성인 기계 윤활유, 그리스, 방청유 등의 폐유를 비중차로 분리수거함으로서 절삭유의 부패 방지 및 환경공채 방지에 크게 기여할 수 있도록 하였다.In the prior art, the invention patent No. 0743899 (registered on July 24, 2007) is a water-soluble cutting oil (washing liquid) which is collected by a scraper-type conveyor and purified through two-stage filtration processes of a drum filter and a turbo filter. It separates sediment gelatin and non-aqueous mechanical lubricants, greases and rust preventive oils contained in it. One side of the machine tool oil tank is equipped with a scraper-type conveyor for collecting sediment such as metal chips. The specific gravity separating plate is installed in an inclined shape, and in front of it, a clean cutting oil collection chamber (waste chamber) and a waste oil collection chamber are formed so that the waste oils such as non-insoluble mechanical lubricants, greases, and rust preventive oils contained in the water-soluble cutting oil are separated and collected by specific gravity. By doing so, it is possible to greatly contribute to preventing corruption of cutting oil and environmental bonds.

그러나 비중 차이에 의한 스크랩퍼식 컨베이어와 드럼필터 및 터보필터 및 비중 분리판을 다수 설치하는 복잡한 구조를 제공하게 되므로 절삭유의 부패 및 변질을 방지할 수 있어 절삭유의 품질향상과 환경공해를 방지할 수 있지만, 공작기계의 내부에 직접 설치해야 하므로 현재 사용하고 있는 공작기계에는 적용할 수 없는 한계가 있으며, 매우 복잡한 구조를 가지고 있으면서 절삭유 고유의 기능을 저하시키는 결점이 있었다.
However, it provides a complex structure that installs a large number of scraper conveyors, drum filters, turbo filters, and specific gravity separators due to the difference in specific gravity, thereby preventing the corruption and deterioration of the cutting oil, thereby improving the quality of the cutting oil and preventing environmental pollution. However, there is a limitation that cannot be applied to the machine tool currently used because it has to be installed directly inside the machine tool, and it has a defect that degrades the function of the coolant while having a very complicated structure.
