Description

Technical Field

[0001] This utility model relates to the field of coal mine dust removal equipment application technology, specifically a mine wet dust collector. Background Technology

[0002] During coal mining, especially in fully mechanized tunneling faces, the crushing of coal and rock by tunneling machines generates a large amount of dust. This dust permeates the working environment, seriously threatening the health of coal miners and causing a persistently high incidence of pneumoconiosis. In order to reduce the harm of dust, wet dust collectors are usually used to purify the air during coal mining.

[0003] However, in reality, traditional wet dust collectors for mining cannot guarantee sufficient contact between coal dust in the air and the washing liquid, resulting in poor dust removal efficiency. Traditional wet dust collectors for mining cannot efficiently and thoroughly dehydrate the air after dust removal. At the same time, traditional wet dust collectors for mining not only waste a lot of water resources, but also result in high dust removal costs. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a wet dust collector for mining.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This utility model provides a wet dust collector for mining, including a front cylinder, a water inlet pipe, a fan, an explosion-proof motor, and a rear cylinder. One end of the front cylinder is connected to an air inlet hood by bolts. The water inlet pipe is located on one side of the air inlet hood. The side of the air inlet hood near the front cylinder is connected to the motor cylinder by bolts. The fan is installed on one side of the outer wall of the motor cylinder. Several impellers are evenly spaced on one side of the fan. The explosion-proof motor is installed on the outer wall of the motor cylinder. One end of the front cylinder away from the air inlet hood is connected to a retaining ring by bolts. One end of the rear cylinder is connected to one side of the retaining ring by bolts.

[0006] Preferably, one end of the water inlet pipe is located in the middle of one side of several impellers, and the motor cylinder is connected to the inner wall of the front cylinder by bolts.

[0007] Preferably, one end of the explosion-proof motor is connected to a guide vane, which is located inside the front cylinder and on one side of several impellers away from the water inlet pipe.

[0008] Preferably, both the front and rear cylinders are cylindrical, the retaining ring is an annular structure, and the bottom of the outer side wall of the front cylinder is connected to a support frame by bolts.

[0009] Preferably, dust baffles are provided at both ends of the inner wall of the rear cylinder. The dust baffles are in the shape of a "W". The end of the rear cylinder away from the retaining ring is connected to an air hood by bolts.

[0010] Preferably, a wall frame is welded to the top center of the outer side wall of the rear cylinder, and nozzles are provided at both ends of the wall frame, with the nozzles at both ends of the wall frame respectively positioned on the top of the two dust baffles.

[0011] Preferably, both the bottom of the front cylinder and the rear cylinder are provided with sewage tanks, and both the bottom of the front cylinder and the rear cylinder are provided with slots that are compatible with the sewage tanks. The sewage tank at one end of the bottom of the front cylinder near the air inlet hood is provided with a drain outlet, and the sewage tank at the end and bottom of the bottom of the rear cylinder away from the retaining ring is provided with a drain outlet.

[0012] The beneficial effects of this utility model are:

[0013] (1) By turning on the fan, the fan drives the impeller to rotate, which is conducive to the high-speed relative motion between the impeller and the airflow when the impeller rotates. This is conducive to the water droplets of washing liquid sprayed from the water inlet pipe and the air dust particles entering the front cylinder through the air inlet hood to clump together. At the same time, in conjunction with turning on the explosion-proof motor, the explosion-proof motor drives the guide vanes to move, which is conducive to the efficient capture of coal dust particles by using inertial collision and diffusion. This is conducive to the more thorough combination of coal dust in the air and washing liquid, thereby ensuring that the dust collector has a better air purification effect.

[0014] (2) By setting a dust baffle on the rear cylinder, it is beneficial for the washing liquid to enter the dust baffle and the air at the same time for dehydration after the washing liquid has completed the mixing and washing action. Secondly, the dust baffle is set into a W-shaped structure, which makes it easier for the dust baffle to optimize the airflow path, prolong the gas-liquid contact time, and improve the interception efficiency of the dust baffle, thereby achieving the dehydration and separation effect. At the same time, the gas purified by this dust collector is not only convenient to be discharged directly into the atmosphere through the air outlet hood, but can also be used as circulating air to achieve zero emissions and reduce air pollution.

[0015] (3) By setting nozzles on both sides of the top of the two dust baffles, it is beneficial for the nozzles to clean the dust baffles regularly, avoiding the accumulation of a large amount of dust on the dust baffles and affecting the subsequent dust removal operation of the dust collector. At the same time, by setting sewage tanks at the bottom of the front cylinder and the rear cylinder, it is convenient to collect the separated washing liquid into the sewage tank. The sewage in the sewage tank is recycled after sedimentation or filtration, which not only reduces water waste, but also reduces the cost of dust removal. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-7 As shown, this utility model discloses a wet dust collector for mining, comprising a front cylinder 1, a water inlet pipe 3, a fan 5, an explosion-proof motor 6, and a rear cylinder 9. One end of the front cylinder 1 is bolted to an air inlet hood 2. The water inlet pipe 3 is located on one side of the air inlet hood 2. The side of the air inlet hood 2 near the front cylinder 1 is bolted to a motor cylinder 4. The fan 5 is installed on one side of the outer wall of the motor cylinder 4. Several impellers 501 are evenly spaced on one side of the fan 5. When the fan 5 is turned on, the fan 5 drives the impellers 501 to rotate, which facilitates the high-speed relative motion between the impellers 501 and the airflow when the impellers 501 rotate. This also facilitates the agglomeration of the washing liquid droplets sprayed from the water inlet pipe 3 and the air dust particles entering the front cylinder 1 through the air inlet hood 2. The explosion-proof motor 6 is installed on the outer wall of the motor cylinder 4. One end of the front cylinder 1 away from the air inlet hood 2 is bolted to a retaining ring 8. One end of the rear cylinder 9 is bolted to one side of the retaining ring 8. One end of the water inlet pipe 3 is connected to a container containing washing liquid.

[0027] One end of the water inlet pipe 3 is located in the middle of one side of several impellers 501. The motor cylinder 4 is connected to the inner wall of the front cylinder 1 by bolts to ensure that the washing liquid sprayed by the water inlet pipe 3 is more dispersed, which is conducive to the washing liquid sprayed by the water inlet pipe 3 coming into more uniform and comprehensive contact with air dust through the impellers 501.

[0028] One end of the explosion-proof motor 6 is connected to a guide vane 601, which is located inside the front cylinder 1 and on one side of several impellers 501 away from the water inlet pipe 3. When the explosion-proof motor 6 is turned on, it drives the guide vane 601 to move, which is beneficial to efficiently capture coal dust particles by using inertial collision and diffusion. This helps the coal dust in the air to combine more thoroughly with the washing liquid, thereby ensuring that the dust collector has a better air purification effect.

[0029] Both the front cylinder 1 and the rear cylinder 9 are cylindrical in shape, and the retaining ring 8 is an annular in shape. By setting the front cylinder 1 and the rear cylinder 9, it is beneficial for the dust collector to perform dust removal and dehydration operations on coal dust. Moreover, the annular structure of both the front cylinder 1 and the rear cylinder 9 is conducive to the impeller 501 and the guide vane 601 to fully mix and disperse the air entering the air inlet hood 2, thereby realizing the full condensation of coal dust and washing liquid into water droplets. The bottom of the outer wall of the front cylinder 1 is connected to the support frame 7 by bolts, which plays a supporting role for the dust collector.

[0030] Dust baffles 15 are provided at both ends of the inner wall of the rear cylinder 9. The dust baffles 15 have a "W" shape. The end of the rear cylinder 9 away from the retaining ring 8 is connected to the air outlet hood 14 by bolts. By providing dust baffles 15 on the rear cylinder 9, it is beneficial for the washing liquid to enter the dust baffles 15 for dehydration after completing the mixing and washing process. Secondly, the dust baffles 15 are set in a W shape, which facilitates the optimization of the airflow path, prolongs the gas-liquid contact time, and improves the interception efficiency of the dust baffles 15, thereby achieving the dehydration and separation function. At the same time, the gas purified by this dust collector can not only be directly discharged into the atmosphere through the air outlet hood 14, but can also be used as circulating air to achieve zero emissions and reduce air pollution.

[0031] A wall frame 10 is welded to the top center of the outer wall of the rear cylinder 9. Spray nozzles 11 are provided on both sides of the wall frame 10. The spray nozzles 11 are connected to a container filled with clean water and can spray clean water. The spray nozzles 11 on both sides of the wall frame 10 are respectively positioned on the top of the two dust baffles 15. By providing spray nozzles 11 on both sides of the top of the two dust baffles 15, it is beneficial for the spray nozzles 11 to clean the dust baffles 15 regularly, and to avoid the accumulation of a large amount of dust on the dust baffles 15, which would affect the subsequent dust removal operation of the dust collector.

[0032] Both the front cylinder 1 and the rear cylinder 9 are equipped with sewage tanks 12 at their bottoms. Both the front cylinder 1 and the rear cylinder 9 have slots at their bottoms that are compatible with the sewage tanks 12. The sewage tank 12 at one end near the bottom of the front cylinder 1, which is close to the air inlet hood 2, has a drain outlet 13. The sewage tank 12 at the end and bottom of the rear cylinder 9, which is away from the retaining ring 8, is equipped with drain outlets 13 for discharging sewage and settled coal dust from the sewage tanks 12. By providing sewage tanks 12 at the bottoms of both the front cylinder 1 and the rear cylinder 9, it is easy to collect the separated washing liquid into the sewage tanks 12. The sewage in the sewage tanks 12 is recycled after sedimentation or filtration, which not only reduces water waste but also reduces dust removal costs.

[0033] In operation, firstly, by turning on the fan 5, the fan 5 drives the impeller 501 to rotate. This facilitates high-speed relative motion between the impeller 501 and the airflow, causing the washing liquid droplets sprayed from the water inlet pipe 3 to agglomerate with the air dust particles entering the front cylinder 1 through the air inlet hood 2. Simultaneously, the explosion-proof motor 6 is turned on, which drives the guide vanes 601 to move. This facilitates the efficient capture of coal dust particles through inertial collision and diffusion, thus ensuring a more thorough combination of coal dust and washing liquid in the air, thereby guaranteeing a better air purification effect of the dust collector.

[0034] Then, after the washing liquid completes the mixing and washing process, it enters the dust baffle 15 at the same time as the air for dehydration. The dust baffle 15 optimizes the airflow path, prolongs the gas-liquid contact time, and improves the interception efficiency of the dust baffle 15, thereby achieving the dehydration and separation function. The purified gas can be directly discharged into the atmosphere through the air outlet hood 14, reducing air pollution.

[0035] Finally, nozzles 11 are installed on both sides of the top of the two dust baffles 15 to clean the dust baffles 15 regularly, so as to avoid the accumulation of a large amount of dust on the dust baffles 15 and affect the subsequent dust removal operation of the dust collector. The sewage in the sewage tank 12 is discharged through the drain outlet 13 after sedimentation or filtration and is recycled.
