The bottom of the box body is provided with a water outlet, and a manual ball valve 35 is arranged on the water outlet. When the adsorbing material needs to be replaced, the manual ball valve 35 needs to be opened to discharge the cutting fluid in the filter box 7.

The working principle of the invention is as follows: when the cutting fluid for cooling and lubricating on the machine tool is collected along with a cutting fluid collecting tank, the cutting fluid flows into a first recovery tank 8 of a recovery tank 5 from a guide pipe, when the first recovery tank 8 starts to overflow, the cutting fluid flows into a second recovery tank 9, when the second recovery tank 9 starts to overflow, the cutting fluid flows into a third recovery tank 10, when the cutting fluid in the third recovery tank 10 starts to overflow, a constant flow pump 11 is started, the cutting fluid in the third recovery tank 10 is sucked into a centrifugal processing tank 6, after centrifugal processing, the cutting fluid and silicon powder in the cutting fluid are further separated, relatively clean cutting fluid flows out from a first liquid outlet, a constant flow pump 13 is started, relatively clean cutting fluid is hydraulically fed into a filter tank 7, the silicon powder in the cutting fluid is thoroughly removed, a constant flow pump 15 is started, and clean cutting fluid is sprayed on a diamond wire from a new nozzle 14. The first recovery tank 8, the second recovery tank 9 and the third recovery tank 10 have the function of collecting silicon powder in the cutting fluid. The adsorbate in the filter box 7 can thoroughly adsorb the silica powder in the cutting fluid. The silicon powder in the device comes from diamond wire cutting silicon ingots and is flushed down along with cutting fluid.
