Abstract

PURPOSE:To automatically separate and recover used cutting oil with high efficiency by separating and extracting cutting oil with a cyclone after eliminating chips from the used cutting oil in a separation tank, and moreover separating and extracting oil from the chips with a centrifugal separator. CONSTITUTION:A used cutting oil, including a chip flowed in a leading gutter 2 via a gutter 1, is scraped out with a scraper 4 to be stored in a separation tank 10 from the dropping port 11 of the tank 10, and the chip deposited in a bottom by gravity is recovered with a carrying conveyer 20. And also a cutting oil separated is overflowed in a receiving tank 13 with a scraper 24 at the time of return via a filtration plate 12. The cutting oil including the fine chip stored in the tank 13 is led to a cyclone 40, separated from a chip part in the cyclone 40, and the cutting oil purified is recovered in a purifying tank through a cutting oil recovery tube. The chip part deposited in the cyclone 40 is sent to a centrifugal separator 50a via a discharge valve 48, and recovered in the purifying tank 14 through a separation recovery tube 51a with the cutting oil which adhered to the chip part separated.

When cutting metal materials with machine tools, lubricating oil (lubricant), generally called cutting oil (cutting agent), is used to prevent friction between the tool and the material and heat generation caused by this. Conventionally, the method of collecting used cutting oil containing chips and fine sludge discharged from machine tools is to introduce this used cutting oil into a filter tank and pass it through multiple filters depending on the particle size of the chips using a pump. A device (Utility Model Publication No. 54-13650) that collects purified cutting oil by forcibly circulating it through a Guide it to the oil receiving plate,
A device that removes chips using a scraper-type conveyor, drips cutting oil from this cutting oil receiving plate through a wire mesh, and stores and collects the purified cutting oil (Japanese Patent Publication No. 59-2641
No. 9) have been proposed.

(Problems to be Solved by the Invention) Conventional cutting oil recovery devices are configured as described above. This requires the use of many filters, and clogging of the filters is unavoidable in machine tools that generate large amounts of chips.
Therefore, it is necessary to clean the filter frequently in a short period of time, which requires maintenance and is not suitable for unmanned operation.Furthermore, the filter cannot be cleaned while the machine tool is in operation, so the machine tool cannot be used 24 hours a day. There was a problem that it could not be operated continuously.

In addition, in the cutting oil recovery device described above, which introduces used cutting oil into a cutting oil receiving plate with small holes and removes chips using a scraper-type conveyor, the holes in the cutting oil receiving plate are It is easy to get clogged, and if the wire mesh is used to filter used cutting oil that contains a large amount of chips, it is easy to get clogged, which requires a lot of maintenance and is not suitable for unmanned operation. This poses a problem in that the recovered purified cutting oil is not suitable for reuse in precision machine processing.

Furthermore, not only is it necessary to secure a worker when cleaning filters or wire mesh, but if cutting oil spills on the floor, workers may slip and get injured, or it may cause a fire, making it safer. This was a problem from a gender perspective. In addition, the chips stored in the chip collection container also have a large amount of cutting oil attached to them, so the cutting oil is carried along with the chips, so the amount of chips is not surprising.
Not only does this increase the amount of cutting oil used (replenishment amount), which increases costs, but it is also undesirable from the standpoint of resource conservation. Further, when the chips are accumulated directly on a predetermined ground surface, there is a problem that the cutting oil adhering to the chips seeps into the ground and contaminates groundwater.

(Effects of the Invention) As described above, according to the present invention, the used cutting oil that has been filtered and separated through the separation layer is purified by a cyclone, separated and recovered, and the cutting oil in the chips is further separated by a centrifuge. As a result, used cutting oil containing chips can be collected with high efficiency and highly clean cutting oil can be obtained, and maintenance work can be simplified to enable 24-hour continuous operation of machine tools, improving work efficiency. It has the effect of improving the
