[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is close to the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly peel off the surface soil layer to mine coal. This is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. In order to allow air circulation between the mine and the outside world, prevent the accumulation of excessive concentrations of toxic and harmful gases such as carbon monoxide and carbon dioxide in the mine, and ensure the personal safety of the workers, the mine will be ventilated.

[0028] Start the fan 2 in the ventilation pipe 1. The fan 2 filters the outside air through the filter plate 5 and then sucks it into the mine for ventilation. When dust and impurities accumulate on the filter plate 5 after filtering for a long time, start the rotating motor 3 on the side of the ventilation pipe 1. The output shaft of the rotating motor 3 rotates to drive the fan 2 to rotate 180°. After the fan 2 rotates 180°, the air outlet faces the filter plate 5. Then the operator pulls the bracket 8 on the mounting plate 4 through the handle 9. The bracket 8 compresses the spring 7 and slides on the slide 6 of the mounting plate 4. The bracket 8 slides and drives the vertical rod 10 and the brush 11 to move from one side of the mounting plate 4 to the other side. Then the drive motor 122 at the end of the vertical rod 10 is started. The output shaft of the drive motor 122 rotates to drive the screw rod 123 to rotate. The screw rod 1 23 rotates and drives the movable block 124 to move toward the bottom of the slide groove 121. The movable block 124 moves toward the bottom of the slide groove 121 so that the bristles of the brush 11 are tightly fitted with the side of the mounting plate 4. Finally, the operator releases the handle 9 and drives the bracket 8 to reset through the restoring force of the spring 7. During the resetting process of the bracket 8, the dust and impurities on the surface of the filter plate 5 are preliminarily cleaned by the bristles. During cleaning, the fan 2 is started to blow away the dust to improve the cleaning effect of the filter plate 5. The reciprocating driving of the brush 11 can clean the surface of the filter plate 5. After the cleaning is completed, the fan 2 is driven again to flip and reset. The coal mine ventilation and dust removal device can facilitate the removal of dust accumulated on the filter plate 5, has a good cleaning effect, improves the ventilation effect of the ventilation pipe 1, is highly safe, and has strong practicality.

[0031] A frame 15 is provided on the side of the filter plate 5 , and the frame 15 is fixed to the mounting plate 4 by screws; this facilitates the subsequent disassembly and assembly of the filter plate 5 , and facilitates the replacement of the filter plate 5 .

[0032] The size of the brush 11 matches the size of the frame 15 , which can improve the cleaning effect of the filter plate 5 .

[0033] The mounting plate 4, the frame 15 and the filter plate 5 are in the same horizontal plane; this can further improve the cleaning effect of the filter plate 5.

[0034] A controller is provided at the handle 9, and the controller is electrically connected to the rotating motor 3 and the driving motor 122;

[0035] Working principle: Start the fan 2 in the ventilation pipe 1, and the fan 2 will filter the outside air through the filter plate 5 and then suck it into the mine to ventilate the inside of the mine. When dust and impurities accumulate on the filter plate 5 after filtering for a long time, start the rotating motor 3 on the side of the ventilation pipe 1, and the output shaft of the rotating motor 3 will rotate to drive the fan 2 to rotate 180°. After the fan 2 rotates 180°, the air outlet faces the filter plate 5. Then the operator pulls the bracket 8 on the mounting plate 4 through the handle 9, and the bracket 8 compresses the spring 7 to slide on the slide 6 of the mounting plate 4. The sliding of the bracket 8 drives the vertical rod 10 and the brush 11 to move from one side of the mounting plate 4 to the other side, and then the driving motor at the end of the vertical rod 10 is started. The machine 122 drives the output shaft of the motor 122 to rotate and drives the screw rod 123 to rotate. The screw rod 123 rotates and drives the movable block 124 to move to the bottom of the slide groove 121. The movable block 124 moves to the bottom of the slide groove 121 so that the bristles of the brush 11 are tightly fitted with the side of the mounting plate 4. Finally, the operator releases the handle 9 and drives the bracket 8 to reset through the restoring force of the spring 7. During the resetting process of the bracket 8, the dust and impurities on the surface of the filter plate 5 are preliminarily cleaned through the bristles. During cleaning, the fan 2 is started to blow away the dust to improve the cleaning effect of the filter plate 5. The reciprocating driving of the brush 11 can clean the surface of the filter plate 5. After cleaning, the fan 2 is driven again to flip and reset.
