[0009] Beneficial effects

[0010] The utility model provides a coolant filtering mechanism for a numerical control lathe, which has the following beneficial effects:

[0011] 1.

By the counterclockwise rotation of the conveyor belt, the iron filings can be transferred to the demagnetization area of the conveyor belt. Due to the disappearance of the magnetic attraction force, the iron filings will fall off the surface of the conveyor belt downward under the action of their own gravity and fall into the right side of the partition plate and be discharged through the chip discharge port, thereby realizing the separation of the coolant and the iron filings;

[0012] 2. The residual iron filings on the surface of the conveyor belt can be scraped off by the scraper, avoiding the influence on the magnetic separation effect caused by the accumulation of iron filings on the surface of the conveyor belt;

[0013] 3. The non-magnetic impurities in the coolant can be filtered by the filter screen;

[0014] 4. The filtered coolant can be pumped out by the water pump for recycling;

[0015] 5. The filter screen can be cleaned by pulling out the filter screen. Description of the drawings

[0024] Embodiment: According to the attached drawings of the specification Figures 1-3It can be known that during use, the coolant doped with iron filings enters the recovery tank 6, then enters the box body 1 through the liquid inlet pipe 10, and falls onto the slide 9. Starting the motor 13 can drive the rotating shaft 5 to rotate. By rotating the rotating shaft 5, the drum 3 can be driven to rotate.
