[0038] Embodiment 1:

[0039] Please combine Figures 1 to 8As shown, the utility model provides a tunnel dust removal device, in which support frames 6 are evenly spaced in the length direction of the tunnel 1, each support frame 6 is fixedly mounted on the inner surface of the tunnel 1, and a spray assembly is mounted on the top of the support frame 6, the spray assembly is composed of a main water pipe 3, a branch pipe 7 and an atomizing nozzle 8; the main water pipe 3 is mounted on a plurality of support frames 6, a water pump is mounted on the main water pipe 3, the water pump is not shown in the figure, a plurality of branch pipes 7 are provided and all are fixedly mounted on the main water pipe 3, and more than one atomizing nozzle 8 is arranged on each branch pipe 7, water is pumped into the main water pipe 3 by the water pump, and sprayed into the tunnel 1 by the plurality of atomizing nozzles 8 to remove dust in the tunnel 1; an air duct 2 is mounted at the bottom end of the support frame 6, a fan 4 is fixedly mounted at one end of the air duct 2, an exhaust pipe 5 is fixedly mounted on the fan 4, and absorption assemblies are evenly spaced in the length direction of the air duct 2, the absorption assembly includes a collection cover 9, a connecting cover 11 and a collection box 10;

[0040] Among them, the connecting cover 11 is fixedly installed on the air duct 2, one end of the collecting cover 9 is fixedly connected to one end of the connecting cover 11, a filter screen 12 is fixedly installed on one end of the collecting cover 9, the collecting box 10 is detachably connected to the collecting cover 9, and a debris discharge port is provided on the collecting cover 9, which is located just above the opening end of the collecting box 10. The spray component sprays water mist into the tunnel 1 for dust removal, and the fan 4 is started at the same time to make each absorption component work. During the suction process, the collecting cover 9 can increase the speed of gas flow in the tunnel 1, and can accelerate the movement of water mist to the bottom of the tunnel 1, thereby increasing the speed of dust removal, and collecting The hood 9 can absorb the water mist that moves to the bottom of the tunnel 1 and reduce the amount of water mist that falls on the ground. Therefore, the ground in the tunnel 1 is not easy to become muddy and affect the normal construction of the workers. The collecting hood 9 also has the function of absorbing dust, and cooperates with the spray component to remove dust from the inside of the tunnel 1, so that the dust removal effect of the dust removal device is better; the water mist and dust absorbed by the collecting hood 9 will contact the filter 12, and the filter 12 will block the dust. The blocked dust and the generated water droplets will eventually fall into the collection box 10 through the discharge port for collection. The staff only needs to clean the collection box 10 regularly.

[0041] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below for details.

[0042] The filter 12 blocks water mist and dust. Most of the dust easily adheres to the surface of the filter 12, which will block the filter holes on the filter 12, affecting the ventilation speed of the filter 12 and weakening the ability of the collection hood 9 to absorb dust and water mist. A scraper 15 is slidably arranged in the length direction of the filter 12; an air pressure drive component is fixedly installed on the collection hood 9, one end of which is connected to the scraper 15, and the other end is connected to the air duct 2. The air pressure drive component enables the scraper 15 to reciprocate in the length direction of the filter 12. During the reciprocating movement, the scraper 15 can scrape the dust adhered to the filter 12 to prevent the dust from clogging the filter 12 and ensuring the ventilation speed of the filter 12. Concave plates 21 are fixedly arranged at both ends of the length direction of the filter 12. When the scraper 15 pushes the dust to the range where the concave plates 21 are located, the dust is separated from the filter 12, loses its adhesion force, and can smoothly fall into the collection box 10;

[0043] The pneumatic drive assembly includes a sleeve 13, a movable rod 14, a spring 17, a connecting pipe 18, a solenoid valve 19 and a pressure relief valve 20; the sleeve 13 is fixedly mounted on the collecting cover 9, and a piston 16 is slidably arranged inside the sleeve 13; one end of the movable rod 14 is fixedly connected to the piston 16, and the other end thereof is fixedly connected to the scraper 15; one end of the spring 17 is fixedly connected to the piston 16, and the other end is fixedly connected to the sleeve 13; the pressure relief valve 20 is fixedly mounted on one end of the sleeve 13, and one end of the sleeve 13 is fixed to the air duct 2 through the connecting pipe 18. The solenoid valve 19 is fixedly installed on the connecting pipe 18. When the solenoid valve 19 is opened and the pressure relief valve 20 is closed, the air duct 2 will extract the cavity gas between the piston 16 and the sleeve 13. At this time, the piston 16 compresses the spring 17 to make the scraper 15 slide along the length direction of the filter screen 12. When the solenoid valve 19 is closed and the pressure relief valve 20 is opened, the scraper 15 is reset under the elastic force of the spring 17. At this time, the internal pressure of the sleeve 13 connected to the connecting pipe 18 returns to normal, so that the scraper 15 can reciprocate in the length direction of the filter screen 12.

[0044] Embodiment three:

[0045] A support rail 22 is fixedly installed on the lower surface of the collecting hood 9, and a track bar 23 is fixedly installed on the top of the collecting box 10. The track bar 23 can slide in the support rail 22. At this time, the collecting box 10 can be supported on the lower surface of the collecting hood 9. A plug rod 24 is slidably provided on the collecting hood 9, and a convex plate 26 is fixedly installed on the top of the collecting box 10. The convex plate 26 is provided with a through hole for the bottom end of the plug rod 24 to pass through. The bottom end of the plug rod 24 is inserted into the through hole, so that the collecting box 10 can be fixed on the collecting hood 9. In this way, the process of disassembling and installing the collecting box 10 is quick and convenient. A limiting ring 25 is fixedly installed on the outer surface of the plug rod 24 to prevent the plug rod 24 from detaching from the collecting hood 9.

[0046] Embodiment 4:

[0047] A first slide rail 27 is fixedly installed at the bottom end of the support frame 6, a first slide bar 29 is fixedly installed on the air duct 2, and the air duct 2 is slidably connected to the first slide rail 27; a second slide rail 28 is fixedly installed on the top end of the support frame 6, a hose 31 is fixedly installed at both ends of the main water pipe 3 in the length direction, a second slide bar 30 is fixedly installed on the main water pipe 3, and the second slide bar 30 is slidably connected to the second slide rail 28. During the mining process, the area where dust is generated will change. The positions of the air duct 2 and the main water pipe 3 can be moved, so that the dust removal device can change its position to remove dust in the area where dust removal is needed, making it more practical.

[0048] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above.
