DETAILED DESCRIPTION

[0019] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts under the premise that no creative efforts are made, belong to the scope of protection of the present application.

[0020] As shown in Figs. 1-2 The machine tool cooling liquid filtering and recycling device of the present application comprises a shell 1, a liquid inlet pipe 2, an overflow pipe 3, a supporting leg 4 and a sewage pipe 5. A motor 6 is fixedly installed at the middle position of the inner cavity of the shell 1. A rotating shaft 7 is fixedly installed at the bottom output shaft of the motor 6. A liquid collecting cover 8 is arranged at the upper position of the inner cavity of the shell 1. A filter plate 9 is fixedly installed at the lower position of the liquid collecting cover 8. A gravel 10 is arranged at the upper position of the filter plate 9. The gravel 10 can filter the small iron filings. A connecting sleeve 11 is arranged between the liquid collecting cover 8 and the filter plate 9. The cooling liquid is guided to the bottom of the inner cavity of the shell 1 through the connecting sleeve 11. The iron filings in the cooling liquid will first be settled. The iron filings with large weight and size will be settled at the bottom of the inner cavity of the shell 1. The filter holes of the filter plate 9 can be effectively prevented from being blocked by the large iron filings. The rotating shaft 7 is located in the connecting sleeve 11. The first cleaning spoke 12 is arranged at the inner cavity position of the connecting sleeve 11. The fixed plate 13 is fixedly installed at the bottom position of the rotating shaft 7. The second cleaning spoke 14 is fixedly arranged at the side of the filter plate 9. The overflow pipe 3 is arranged at one end of the inner cavity of the shell 1 between the gravel 10 and the liquid collecting cover 8.

[0021] Further, the liquid collecting cover 8 is in the form of a funnel.

[0022] Further, the bottom of the shell 1 is in the form of a funnel.

[0023] Working principle: The cooling liquid is injected into the inner cavity of the shell 1 through the liquid inlet 2. When the gravel 10 above is extracted by the overflow pipe 3, the cooling liquid injected through the liquid inlet 2 will be supplemented to the bottom of the inner cavity of the shell 1 through the liquid collecting cover 8 and the connecting sleeve 11. The iron filings in the cooling liquid will be settled at the bottom of the inner cavity of the shell 1 under the action of the liquid collecting cover 8 and the connecting sleeve 11 and its own gravity. The relatively small metal debris will be filtered by the gravel. In the process of slowly rotating the rotating shaft 7 driven by the motor 6, the first cleaning spoke 12 can clean the inner wall of the connecting sleeve 11, and the second cleaning spoke 14 can clean the bottom of the filter plate 9. When the iron filings at the bottom of the inner cavity of the shell 1 need to be removed, the liquid inlet of the liquid inlet pipe 2 and the liquid outlet of the overflow pipe 3 are closed, and the switch valve on the sewage pipe 5 is opened at the same time. The iron filings at the bottom of the inner cavity of the shell 1 and the residual cooling liquid in the shell 1 are discharged together.
