[0052] Embodiment 2:

[0053] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 , an anti-pollution filtering device for an electric spark wire cutting machine tool is basically the same as Example 1, and further, the transmission component includes a pressure relief pipe 8 and a pipe three 9, the pressure relief pipe 8 is fixedly connected to the outer wall of the filter separation box 704, the pipe three 9 is fixedly connected to the outer wall of the water storage frame 3, one end of the pressure relief pipe 8 is connected to the inner cavity of the sleeve 6, and the other end is connected to the air inlet end of the pipe three 9, the air outlet end of the pipe three 9 is connected to the air nozzle 903, and an impeller three 904 is fixedly installed on one end of the rotating shaft 901 passing through the pipe three 9.

[0054] The air suction pump 7 is connected to the inner cavity of the dust collecting cover 702 through the pipeline 1 701 , and the air suction pump 7 is connected to the inner cavity of the filter separation box 704 through the pipeline 2 703 .

The filter screen 705 and the guide rod 802 are fixedly connected to the inner wall of the filter separation box 704. The reciprocating screw rod 801 is rotatably connected to the inner wall of the filter separation box 704. An impeller 804 is fixedly installed on one end of the reciprocating screw rod 801 that passes through the pressure relief pipe 8. A scraper 803 is threadedly connected to the reciprocating screw rod 801. The scraper 803 is slidably connected to the guide rod 802. Sewage outlets 805 are provided on the outer walls on both sides of the filter separation box 704.

[0056] When cutting the workpiece to be cut, start the suction pump 7. The suction pump 7 enables the dust collecting hood 702 to generate adsorption capacity through the pipe 1 701, so that the dust collecting hood 702 can absorb and collect the debris generated by the electrode wire 205 cutting the workpiece and the coolant sprayed by the atomizing nozzle 305 to cool the electrode wire 205, thereby effectively preventing the debris and coolant from splashing around and polluting the processing environment. The debris and coolant are then transported into the filter separation box 704 through the pipe 2 703. The debris and coolant discharged into the filter separation box 704 come into contact with the filter screen 705, so that the filter screen 705 can block the debris, and the coolant passes through the filter screen 705 and falls into the bottom of the filter separation box 704, and then flows back into the water storage frame 3 through the drain pipe 706 for recycling. , thereby reducing the waste of coolant.

When the air pressure entering the sleeve 6 is greater than the safety value set by the pressure relief valve connected to the pressure relief pipe 8, the pressure relief valve automatically opens to relieve pressure. At this time, part of the gas in the sleeve 6 is transported to the air nozzle 903 through the pressure relief pipe 8 and the pipeline three 9 for spraying. The sprayed gas can drive the coolant circulating in the water storage frame 3 to generate bubbles and move upward, thereby achieving the preliminary heat dissipation effect of the heated coolant circulating in the water storage frame 3.

[0057] At the same time, when the gas passes through the pressure relief pipe 8, the gas drives the reciprocating screw rod 801 to rotate through the impeller 804, and the reciprocating screw rod 801 drives the scraper 803 to fit the upper surface of the filter screen 705 and reciprocate left and right under the guide limit of the guide rod 802, so that the workpiece debris blocked on the filter screen 705 can be automatically cleaned, and the cleaned workpiece debris is discharged from the filter separation box 704 through the sewage outlet 805. At the same time, when the gas passes through the pipeline 9, the gas drives the rotating shaft 901 to rotate through the impeller 904, and the rotating shaft 901 drives the dial plate 902 and the air nozzle 903 to rotate, so that the rotating dial plate 902 can move the heated coolant in the water storage frame 3 to fully contact with the gas ejected from the air nozzle 903, thereby further improving the heat dissipation effect of the heated coolant circulating in the water storage frame 3.

[0058] It should be noted that the pipeline three 9 is arranged in two sections, one end of which is placed in the rotating shaft 901 and connected to the air nozzle 903, and the other end is connected to the air outlet end of the pressure relief pipe 8, and the connected ends of the two sections are connected through a rotating joint provided on the rotating shaft 901. Therefore, the pipeline three 9 will not interfere with the rotation of the rotating shaft 901.
