A coolant liquid cleaning apparatus according to the present embodiment when sludge discharged from two processing mother machines is a magnetic material will be described with reference to FIGS. The cleaning apparatus includes two sets of magnetic separators 11, two sets of circular coolant tanks 12 connected to the two sets of magnetic separators 11, and two sets of circular coolant tanks 12 provided on two sets of circular coolant tanks 12. For pumping the coolant liquid, which is provided so as to connect the immersion coolant pump 13 for cooling liquid circulation and the two sets of circular coolant tanks 12 and in which the sludge in the coolant liquid has been separated, to two machining base machines. The pump chamber 15 includes one coolant pump 14. The coolant liquid containing the magnetic sludge discharged from the two processing mother machines first flows into the two magnetic separators 11 installed for the two processing mother machines and separates the sludge in the coolant liquid. Processing is performed. The magnetic separator 11 includes a non-magnetic rotating cylinder in which a rotating cylinder 16 having a fixed magnet built therein is rotated by an electric motor 17, and a flow path in which a predetermined gap is formed between the rotating cylinder 16 and a semi-cylindrical bottom plate 18. The sludge of the coolant is separated by passing a coolant containing a sludge of the magnetic substance through the inside of the cylinder 19 and adsorbing and separating the sludge of the magnetic substance in the coolant on the outer periphery of the rotary cylinder 16. The coolant liquid after the sludge separation process in the coolant liquid flowing out of the magnetic separator 11 flows into the two sets of circular coolant tanks 12 in a tangential direction. The magnetic sludge adsorbed on the outer periphery of the rotary cylinder 16 is pressed by the squeezing roller 20 to be dehydrated, scraped off by the scraping plate 21, and discharged into the sludge box 22.

The vortex 26 is generated in the coolant, and the fine sludge and the like in the coolant that cannot be collected by the magnetic separator 11 continue to settle while rotating together with the coolant. Collect on the bottom. The strength of the vortex 26 can be adjusted by adjusting the flow rate of the coolant ejected from the coolant ejection nozzle 25 with the flow adjustment valve 27. The center bottom of the two sets of circular coolant tanks 12 has the upper surface of the pump suction port 29 of the casing 28 of the immersion coolant pump 13 for circulating the coolant liquid flush with the bottom of the circular coolant tank 12 or less. As a result, the pump casing 28 can be embedded in the bottom of the circular coolant tank 12. As a result, fine sludge and the like in the coolant that could not be collected by the magnetic separator 11 integrated on the bottom of the central portion of the two sets of circular coolant tanks 12 due to the vortex 26 are immersed coolants for coolant circulation. Most of the liquid is sucked by the pump 13 and is again fed into the magnetic separator 11 to separate sludge in the coolant liquid again.

The pump chamber 15 is provided with a coolant pump 14 for performing cooling, and the two sets of circular coolant tanks 12 and the pump chamber 15 communicate with each other through cutout holes 31 having an underflow structure. In the middle of the discharge pipe 23 of the coolant pump 14, two T-shaped connection pipes 24 are provided as described above, and a part of the coolant is provided in a tangential direction in the two sets of the circular coolant tank 12. The coolant is discharged into the two sets of circular coolant tanks 12 via two coolant discharge nozzles 25.
