The present invention relates to a contaminated liquid purifying apparatus, and more particularly, to a contaminated liquid purifying apparatus in which a part of purified liquid is injected in the process of purifying the contaminated liquid to simultaneously wash the perforated plate.

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) (hereinafter referred to as lubricating oil) .Cutting oil and sliding oil are circulated by mixing small chips, cutting powder, and foreign substances generated during machining of workpieces, and most impurities are stored in the bottom of the cutting oil tank. Precipitates, corrodes and rots.

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.

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.

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 power loss, and overheating of the cutting and cutting tools due to the supply of the cutting oil during processing. The efficiency of the cutting tool is reduced, and the cutting tool is damaged or severely worn. Thus, there is a problem that the work efficiency is reduced due to the loss of time due to the replacement of the cutting tool and the stop of the equipment.

However, even if the cutting oil is purified, a small amount of cutting chips are contained in the purified cutting oil, and thus, when the purified cutting oil is supplied to the machine tool or the like in the purification apparatus of the prior art, it causes damage to the mechanical parts by the cutting chips. can do.

Therefore, a purifier such as the prior art is provided with a separate bag filter equipment for filtering out the fine cutting chips remaining in the cutting oil. However, the bag filter equipment also requires frequent filter replacement due to a drastic drop in filter efficiency over time, and the supply of coolant is interrupted during such filter replacement, which leads to problems in workability and productivity. do.
