おいて特に著しい。Conventionally, in such a one-lunt purification system, if the coolant returned from the processing machine to the settling tank contains chips of light metals such as aluminum alloy, floating chips will be generated on the surface of the coolant in the settling tank. Although it is easy to do so, if the coolant surface is almost covered with floating chips, the coolant surface will not be in contact with the outside air, which will cause the coolant to rot when the coolant purification device is stopped, leading to a decrease in coolant performance. This is particularly noticeable in water-soluble coolants where fats and oils float to the surface.

A coolant return device is installed between the purifying liquid tank and the sedimentation tank so that the water can be raised, and a nozzle is installed to propel the floating chips on the surface of the coolant at the constant water level toward the opening for sedimentation detection. The pump is characterized in that a valve is attached to the discharge side of the pump so as to selectively connect the conduit to the filter and the conduit to the nozzle.
