WIPO Patent Application WO/2022/181032
Kind Code:
A1
Abstract:
Provided is a filtration device enabling more efficient treatment of foreign matter included in a liquid discharged from a machine tool. A filtration device as in one embodiment of the present invention comprises: a tank unit having a first tank into which a liquid containing foreign matter flows; and a pump that is provided to a middle part of the first tank and discharges the liquid that has collected in the first tank. The first tank comprises: a bottom surface; four side surfaces connected to the bottom surface; four corners at which the bottom surface and two side surfaces out of the four side surfaces are respectively connected; and four inclined surfaces for respectively covering the four corners. The four inclined surfaces are inclined so as to draw closer to the bottom surface going toward the middle part from a connecting part where the two side surfaces are connected. The liquid flowing into the first tank causes a vortex to occur inside the first tank, gathering the foreign matter at the middle part of the first tank, and the foreign matter is then discharged by the pump.
