[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a CNC machine tool coolant filter device, including a filter box, two pairs of support rods are fixedly connected between the left wall and the right wall of the filter box, a drawer is provided above the support rod, a liquid outlet is opened on the bottom surface of the drawer, an overflow plate is fixedly provided on the upper inner surface of the drawer and located on the right side of the liquid outlet, a return strip is fixedly provided on the lower inner surface of the drawer, a detachable filter plate is installed on the upper surface of the return strip, a liquid inlet pipe is connected to the upper wall of the filter box and located on the right side of the overflow plate, and the bottom of the filter box is connected to a drain pipe.

[0007] Preferably, the right wall of the filter box is provided with two through openings, and the bottom edges of the through openings are higher than the support rods.

[0008] Preferably, a pair of limit plates are fixedly connected to the bottom surface of the drawer, and the limit plates are in contact with the support rods.

[0009] Preferably, a water pump is installed on the drainage pipe.

[0010] Preferably, a handle is fixedly connected to the right surface of the drawer.

[0011] Beneficial effects:

[0012] The utility model provides a cooling liquid filtering device for a CNC machine tool, which has the following beneficial effects:

[0013] By providing an overflow plate, iron filings in the coolant can be precipitated in the upper drawer, so that the coolant can be filtered. The coolant overflows to the left side of the overflow plate and flows into the lower drawer through the liquid outlet of the upper drawer. The coolant can be further filtered through the filter plate. The coolant can be pumped out through the drain pipe by starting the water pump. After the filtration is completed, the drawer can be pulled out from the opening by holding the handle and lifting the right end of the drawer. BRIEF DESCRIPTION OF THE DRAWINGS
