[0031] Among them, the structure such as motor is prior art, will not repeat; At the same time, the utility model still includes power supply, controller and switch etc., it is not the main technical point of this patent, will not repeat. The wiring diagram of the motor in the utility model belongs to the common knowledge in the art, and its working principle is already known technology, and its model is selected according to actual use, so the motor will not be explained in detail Control mode and wiring arrangement.

[0032] Working principle and process: when the cutting fluid is filtered, first start the self-priming pump 14, at this time the self-priming pump 14 through the water outlet pipe 13 stored in the cutting fluid recycling tank 12, cutting fluid is extracted, at this time when the cutting fluid sent to the centrifugal pump 15, at this time start centrifugal pump 15, self-priming pump 14 power off, at this time the centrifugal pump 15 through the water inlet pipe 16 cutting fluid is constantly sent to the inside of the detection box 21, pressure transmitter 28 can detect the pressure in the water inlet pipe 16, so as to feedback the state of the filter plate 22, then the filtered cutting fluid flows into the cutting fluid tank in the machine tool through the circulating pipe 27 again;

[0033] At this time the filter plate 22 in the detection box 21 carries on the filtration to the cutting fluid, with the continuous filtration of cutting fluid, at this time the filter plate 22 inside accumulates a large amount of cutting impurities, with the gradually increasing of the gravity of filter plate 22, at this time the filter plate 22 slides on the surface of guide rod 24, guide rod 24 can guide the moving position of filter plate 22, filter plate 22 in the process of sliding extrusion reset spring 29, so that the reset spring 29 deformation, reset spring 29 can reset the position of filter plate 22, at this time the filter plate 22 drives the extrusion block 25 to move down, the extrusion block 25 moves to the weighing sensor 26 after sticking, at this time the weighing sensor 26 carries on the weighing treatment to the cutting impurities accumulated in the filter plate 22, so as to make the feedback of the weight of cutting impurities accumulation, so that the operator cleans the cutting impurities accumulated in the filter plate 22, when the cutting impurities accumulated in the filter plate 22 is cleaned, at this time the weight of filter plate 22 is reduced, and the reset spring 29 drives the filter plate 22 to reset;
