[0002] A CNC machine tool is an automated machine tool equipped with a program control system. During CNC machine tool processing, the rapid rotation of the workpiece and the contact between the tool generate a large amount of heat, which needs to be cooled by coolant. During the processing of iron parts, a large amount of iron filings will be generated, and these iron filings will remain in the coolant. The coolant is not a disposable item. After filtering the coolant through the filter device of the CNC machine tool, it can be recycled.

[0003] For example, in the utility model patent with announcement number CN217914330U, a coolant filter box for a CNC machine tool is disclosed, including a filter structure, wherein the filter structure includes a machine tool body, a filter box is fixedly connected to the front side of the machine tool body, a liquid inlet pipe is fixedly connected to the right side of the filter box, a liquid outlet pipe is fixedly connected to the left side of the filter box, the liquid inlet pipe and the liquid outlet pipe are fixedly connected to the machine tool body, and a fixed block is fixedly connected to the lower side of the filter box.

[0004] However, when the utility model is in use, iron filings cannot be automatically discharged, resulting in iron filings piling up on the filter plate, which causes the filter plate to be clogged. Workers need to clean the filter plate frequently, which increases the workers' labor intensity and results in poor use effect. Utility Model Content

[0021] Embodiment: According to the specification attached Figure 1-2 It can be known that when in use, the liquid inlet pipe 2 is connected to the coolant discharge port of the CNC machine tool, and the liquid outlet pipe 17 is connected to the coolant inlet port of the CNC machine tool. The starting motor 7 can drive the active bevel gear 8 to rotate, and the rotation of the active bevel gear 8 can drive the driven bevel gear 10 to rotate, and the rotation of the driven bevel gear 10 can drive the hollow shaft 9 to rotate, and the rotation of the hollow shaft 9 can drive the rotating drum 5 to rotate counterclockwise. The coolant containing iron filings generated by the CNC machine tool enters the box body 1 through the liquid inlet pipe 2 and falls into the left side of the rotating drum 5.

The drum 5 continues to rotate counterclockwise, and the iron chips remaining on the side surface of the drum 5 can be scraped off by the scraper 6, avoiding the influence of the magnetic separation effect on the accumulation of iron chips on the outer surface of the drum 5. The coolant that removes the iron chips is gradually separated from the drum 5 by its own gravity and falls into the left side of the partition 13 and flows into the filter box 15. The non-magnetic impurities in the coolant can be filtered through the filter plate 11, and the filtered coolant can be pumped out for recycling by the water pump 16. The filter plate 11 can be pulled out to clean the filter plate 11.
