[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 6This utility model provides a technical solution: a wet dust collector for mining, including a dust collection cylinder 1, a water spray assembly 3 fixedly connected to the upper surface of the dust collection cylinder 1, an exhaust duct 2 fixedly connected to the rear end of the dust collection cylinder 1, and a filter assembly 4 slidably connected to the lower surface of the dust collection cylinder 1. The filter assembly 4 includes a filter box 408, a vibration motor 401 fixedly connected to the outer surface of one end of the filter box 408, a connecting turntable 404 fixedly connected to the output shaft end of the vibration motor 401, a rotating column 405 fixedly connected to the eccentric part of the surface of the connecting turntable 404, a connecting rod 406 rotatably connected to the rotating column 405, a filter screen 407 rotatably connected to the other end of the connecting rod 406, springs 403 fixedly connected to the lower surfaces of both ends of the filter screen 407, a telescopic rod 402 provided inside the springs 403, the upper end of the telescopic rod 402 fixedly connected to the lower surface of the filter screen 407, and fixed to the outside of the filter box 408 by the vibration motor 401, and rotated eccentrically. The high-frequency vibration is generated, and the output shaft is connected to the turntable 404. The rotating column 405 at the eccentric part of the turntable rotates with the motor, driving the linkage mechanism to move. One end of the connecting rod 406 is sleeved on the rotating column 405, and the other end is rotatably connected to the filter screen 407. The circular motion of the turntable is converted into the reciprocating vibration of the filter screen. It is supported by the spring 403 and the telescopic rod 402. During vibration, the spring 403 absorbs the impact, and the telescopic rod 402 ensures vertical stability and prevents the filter screen from shifting. When the filter screen traps too much dust, water will be blocked above the dust and cannot penetrate. The vibration motor 401 starts, driving the filter screen to vibrate at high frequency, causing the dust to shake above the filter screen 407, preventing the filter screen 407 from clogging. The water that needs to fall into the filter box 408 is allowed to flow downward again through the vibration of the filter screen 407, avoiding the formation of "water layer accumulation". This allows the water to pass through the filter screen smoothly and fall into the bottom of the filter box 408, maintaining the normal water circulation of the filtration system.

[0026] Reference Figure 4 , Figure 5A water pump 301 is fixedly connected to the upper surface of the vacuum cleaner 1. A water pump pipe 307 is fixedly connected to the input end of the water pump 301. The other end of the water pump pipe 307 is fixedly connected to the filter box 408. A water outlet pipe 302 is fixedly connected to the output end of the water pump 301. A water tank 303 is fixedly connected to the other end of the water outlet pipe 302. An activated carbon filter 304 is installed at one end of the water tank 303. A water tank 305 is installed at the other end of the activated carbon filter 304. The activated carbon filter 304 is slidably connected to the inner side wall at the connection between the activated carbon filter 304 and the water tank 303 and the water tank 305. A booster pump 308 is fixedly connected inside the water tank 305. A connecting pipe 309 is fixedly connected to the output end of the booster pump 308. A spray pipe 306 is fixedly connected to the other end of the connecting pipe 309. When the mine wet dust collector is running, the wastewater filtered in the filter box 408 is pumped to water tank 303 through the pumping pipe 307 when the wastewater level reaches the extraction point. After preliminary sedimentation, the wastewater passes through the activated carbon filter 304, which adsorbs organic matter, odors, and residual dust in the water. The purified water is then stored in water tank 305. When water spraying is required for dust removal, the booster pump 308 is started to pressurize the clean water in water tank 305 and deliver it to the water spray assembly 3 through the connecting pipe 309 and the spray pipe 306 for spray dust removal, thus realizing the recycling of water resources.

[0027] Reference Figure 2 The other end of the water spray pipe 306 passes through the front of the upper end of the dust collection cylinder 1 and is fixedly connected to an annular pipe 101. Several water spray nozzles 102 are fixedly connected to the surface of the annular pipe 101. A first filter plate 103 and a second filter plate 104 are arranged in front of the several water spray nozzles 102. The first filter plate 103 and the second filter plate 104 are both fixedly connected to the top of the inner wall of the dust collection cylinder 1. A drive motor 107 is arranged behind the second filter plate 104. An impeller 105 is fixedly connected to the output shaft of the drive motor 107. A motor protective cover 108 is sleeved on the surface of the drive motor 107. The outer surface of the motor protective cover 108 All are fixedly connected with guide vanes 109, and the other end of the guide vanes 109 is fixedly connected to the inner wall of the dust collection cylinder 1. The lower end of the inside of the dust collection cylinder 1 is fixedly connected with a water filter tank 106. Dust-laden air enters the dust collection cylinder 1 under negative pressure. It first passes through the first filter plate 103, which intercepts larger dust particles. Then it mixes thoroughly with the water mist sprayed from the water nozzle 102. The dust particles are moistened by the water mist and become heavier. Under the action of gravity, they settle downwards. Some dust falls into the water filter tank 106. The remaining dust-laden air continues to flow backwards and passes through the second filter plate 104 to further filter fine dust. Then it enters the exhaust duct 2.

[0028] Reference Figure 3An annular filter 110 is fixedly connected inside the exhaust duct 2. One end of the annular filter 110 is fixedly connected to an air outlet filter plate 112. Several fixing posts 111 are provided on the outer surface of the air outlet filter plate 112. The other end of the fixing posts 111 is fixedly connected to the inner surface of the exhaust duct 2. The air after being cleaned by the dust collection cylinder 1 enters the exhaust duct 2. First, it is initially filtered by the annular filter 110 to intercept larger dust particles remaining in the air. Then, it undergoes secondary fine filtration through the air outlet filter plate 112 to further filter out fine dust particles in the air, so that the exhaust air meets environmental protection standards. Finally, the purified air is discharged from the work area through the exhaust duct.

[0029] Reference Figure 1 , Figure 6 The lower end of the dust collection cylinder 1 is provided with sliding grooves 409 on both sides near the upper end of the filter box 408. The upper end of the filter box 408 is fixedly connected to sliding rods 410 on both sides. The upper end of the filter box 408 is slidably connected to the inner wall of the sliding grooves 409 through the sliding rods 410. The lower surface of the dust collection cylinder 1 is fixedly connected to both ends of the base 5. The opposite side of the base 5 is fixedly connected to the connecting column 6. When the dust and sludge collected on the filter screen 407 above the filter box 408 reaches a certain amount, the filter box 408 can be pulled out from below the dust collection cylinder 1 by pulling it along the sliding connection structure of the sliding grooves 409 and the sliding rods 410. Then the filter box 408 is cleaned, the dust is emptied, and it is reinstalled in its original position. Timely maintenance and upkeep are necessary to ensure the normal operation of the equipment.

[0030] Working principle and usage process of this utility model:

[0031] After the drive motor 107 is powered on, its output shaft drives the impeller 105 to rotate at high speed. The rotation of the impeller 105 generates a strong centrifugal force, creating a negative pressure environment inside the dust collection cylinder 1. Based on the principle of atmospheric pressure difference, external dust-laden air is drawn in from the front end of the dust collection cylinder 1 under atmospheric pressure. After entering the dust collection cylinder 1, the dust-laden air passes through the first filter plate 103, which can intercept larger dust particles for preliminary filtration. Purified water in the second water tank 305 is pumped by the booster pump 308 through the connecting pipe 309 and the spray pipe 306 to the annular pipe 101. The spray nozzles 102 on the surface of the annular pipe 101 spray water in a mist form, forming a fine water mist. After passing through the first filter plate 103, the dust-laden air is fully mixed with the water mist. After the dust particles come into contact with the water mist, they are moistened and become heavier, and then settle downwards under gravity. Subsequently, the dust-laden air continues to flow backwards. The dust particles pass through the second filter plate 104, which further intercepts fine dust particles. The settled and intercepted dust and water fall into the filter assembly 4 at the lower end of the water filtration tank 106 inside the dust collection cylinder 1. After the vibration motor 401 in the filter assembly 4 is powered on, its output shaft drives the connecting turntable 404 to rotate. Since the rotating column 405 is fixed at the eccentric position on the surface of the connecting turntable 404, the rotating column 405 makes a circular motion when the connecting turntable 404 rotates. The rotating column 405 drives the filter screen 407 to swing back and forth through the connecting rod 406. During the swinging process, the dust trapped on the filter screen 407 is subjected to vibration force. The high-frequency vibration causes the dust to shake on the surface of the filter screen, which breaks the tight structure formed by the accumulation of dust, promotes the dust to fall off or redistribute, and prevents the dust from solidifying and accumulating in the filter screen pores, thereby maintaining the permeability of the filter screen and ensuring that the water flow can continuously penetrate the filter screen to complete the filtration.

[0032] Spring 403 and telescopic rod 402 provide support and cushioning for filter screen 407, ensuring stable operation of filter screen 407 during vibration. Filter box 408 is slidably connected to the slide groove 409 at the lower end of dust collection cylinder 1 via slide rod 410. When the dust collection box 408 is full, it can be easily pulled out for cleaning. Under the action of water pump 301, filtered water is pumped to water tank 1 303 through water pipe 307. Activated carbon filter screen 304 in water tank 1 303 performs deep purification treatment on sewage. Activated carbon filter screen 304 uses its rich pore structure and strong adsorption capacity to adsorb organic matter, odor substances, and residual fine dust particles and other impurities in sewage. Water purified by activated carbon filter screen 304 flows into water tank 2 305. Water in water tank 2 305 is then pumped by booster pump 308 to enter the next round of water spraying and dust removal cycle, thereby realizing the recycling of water resources.

[0033] After being treated by the dust removal cylinder 1, the air enters the exhaust duct 2. The annular filter 110 inside the exhaust duct 2 further filters the air, intercepting larger dust particles remaining in the air. Then, the air continues to flow forward and undergoes secondary fine filtration through the outlet filter plate 112. The outlet filter plate 112 is securely installed inside the exhaust duct 2 by the fixing column 111 to ensure the filtration effect. The purified air after double filtration is finally discharged through the outlet of the exhaust duct 2.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
