Description

Technical Field

[0001] The invention belongs to the technical field of dust removal, in particular to a wet-type coal mine dust collector. Background Art

[0002] The operating principle of a wet dust collector is that dust-laden gas enters the dust collector and comes into contact with atomized water droplets. Through inertial collision, interception, diffusion, and agglomeration, dust particles combine with the water droplets to form larger clusters. These clusters then settle to the bottom of the dust collector under the action of gravity and are discharged through the drainage system. The purified gas is then discharged through the exhaust port. During operation, some dust will fall onto the nozzles during dust removal. When the wet dust collector is not in use, due to the constant presence of dust in the underground coal mine environment, some dust will still enter the wet dust collector and adhere to the nozzles. Over time, dust accumulates, gradually clogging the nozzles and affecting the proper functioning of the spray system. When a nozzle is clogged, the area it was originally responsible for spraying will lose its water mist coverage. When the dust-laden airflow passes through the dust collector, it will preferentially choose a path with less resistance (i.e., an area without water mist or with sparse water mist), thereby bypassing the normal dust removal area and forming an airflow short circuit. Air flow short-circuiting causes dust-laden gas to be discharged without sufficient dust removal treatment. A large amount of dust cannot be effectively removed, resulting in excessive dust concentration in the exhaust gas and failure to meet environmental emission standards, seriously affecting the normal production of the coal mine and the quality of the surrounding environment.

[0012] The beneficial effects of the present invention are as follows: 1. The wet coal mine dust collector described in the present invention can prevent external dust from entering the riser through the air duct by blocking the air inlet with the first annular plate, and then entering the dust removal chamber through the air inlet and adhering to the spray assembly, gradually clogging the nozzle, resulting in an air flow short circuit in the subsequent dust removal process, causing the exhaust gas dust concentration to exceed the standard and fail to meet the environmental emission standards. At the same time, by using the slide plate and the first annular plate to scrape the dust in the dust removal chamber and between the riser and the vertical cylinder, the residual dust can be pushed out, avoiding the increase of residual dust in the dust removal chamber and the vertical cylinder, which will increase the risk of clogging the spray assembly.

[0013] 2. The wet coal mine dust collector described in the present invention can divert the dust gas entering the vertical pipe by providing multiple dust removal chambers, and divert the dust into different dust removal chambers, and then reduce the diverted dust through the spray components respectively. In this process, the dust can be dispersed to avoid the dust from gathering together, resulting in excessive dust density. When reducing the concentrated dust, the atomized water droplets cannot fully contact the dust, resulting in part of the dust being discharged into the external environment again, thereby reducing the dust removal effect. At the same time, dust with too high a density is more likely to adhere to the spray component, causing the spray component to be blocked.

[0014] 3. The wet coal mine dust collector described in the present invention has an intelligent flow meter installed on the hose connected to the nozzle, and the intelligent flow meter is connected to the computer through a communication module. Therefore, the value change of the intelligent flow meter when the liquid passes through can be monitored by the computer. If the value on a certain intelligent flow meter is monitored to be unchanged for a long time, it can be determined that the nozzle connected to the intelligent flow meter is blocked. At this time, the control valves in the air inlet and the air outlet in the dust removal chamber where the nozzle is located are controlled to be closed, so that the dust cannot enter the dust removal chamber through the air inlet. Therefore, the dust removal chamber is in a closed state. In this process, the dust removal chamber with a blocked nozzle can be closed, thereby avoiding the use of the dust removal chamber with a blocked nozzle to reduce dust, resulting in the inability to effectively remove the dust, so that this part of the dust is still discharged into the external environment.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figures 1 to 11 As shown, the wet-type coal mine dust collector of the present invention includes a wet dust collector; the wet dust collector includes a standpipe 1; an air duct 3 is installed at the bottom of the standpipe 1; a vertical cylinder 11 is provided in the standpipe 1, and the top of the vertical cylinder 11 is fixedly connected to the standpipe 1 through a second annular plate 12; the bottom of the vertical cylinder 11 is frustum-shaped; a distance is left between the vertical cylinder 11 and the standpipe 1; A first annular plate 13 slides on the vertical tube 11; the outer ring of the first annular plate 13 is located on the vertical tube 1 and has multiple air inlets 14, and the first annular plate 13 is initially located below the air inlets 14; the outer ring of the second annular plate 12 is located on the vertical tube 1 and has multiple air outlets 15. The outer ring of the riser 1 is fixedly connected to the annular partition 2, and the top of the annular partition 2 is closed; multiple partition groups are fixedly connected to the annular partition 2, and each partition group includes two partitions 21; the space between the two partitions 21 of the partition group is a dust removal chamber 22; and the air inlet 14 and the air outlet 15 are both located in the dust removal chamber 22; A slide 23 slides in each of the dust removal chambers 22, and in its initial state, the slide 23 is located above the air inlet 14; a cylinder 24 is fixedly connected to the slide 23, and the cylinder 24 extends above the annular partition 2; two rectangular cylinders 25 are fixedly connected above the first annular plate 13, and the two rectangular cylinders 25 are respectively located on the left and right sides of the vertical cylinder 11; The rectangular tube 25 passes through the second annular plate 12 and extends to the top of the riser 1; a third annular plate 26 is provided above the riser 1, and the cylinder 24 and the rectangular tube 25 are both fixedly connected to the third annular plate 26; an electric push rod 27 is fixedly connected to the outer ring of the annular partition 2, and the extension rod of the electric push rod 27 is fixedly connected to the third annular plate 26; Each of the dust removal chambers 22 is provided with a spray assembly, and the spray assembly is used to reduce dust on the passing gas; In this embodiment, a first motor is installed in the air duct 3; the first motor is installed in a protective shell; and a vortex blade 31 is installed on the first motor; An annular bin 32 is fixedly connected to the bottom of the annular partition 2; a plurality of spacers 33 are fixedly connected to the annular bin 32, and the spacers 33 correspond to the partitions 21 one by one and fit together; A rectangular bin 34 is fixedly connected to the bottom of the riser 1, and the annular bin 32 is connected to the rectangular bin 34 through a conduit; a base is provided below the rectangular bin 34; a fixing ring 35 is fixedly connected to the outer ring of the annular partition 2, and the fixing ring 35 is fixedly connected to the base through supporting legs.

[0020] When processing the dust in the mining area, the wet dust collector is first started. The wet dust collector will control the spray assembly to work, and then control the electric push rod 27 to extend. The extended electric push rod 27 will drive the third annular plate 26 to move upward. The upward third annular plate 26 will gradually pull multiple cylinders 24 and two rectangular cylinders 25 to move upward. In the process of the rectangular cylinder 25 moving upward, the first annular plate 13 will be pulled upward along the vertical cylinder 11, and finally the first annular plate 13 will be moved up to the position below the air outlet 15. In the process of the multiple cylinders 24 moving upward, the slide 23 in each dust removal chamber 22 will be pulled up respectively. When the slide 23 moves up to above the air outlet 15, the electric push rod 27 is controlled to stop working.

[0021] Subsequently, controlling the first motor will drive the vortex blades 31 to rotate, and the rotating vortex blades 31 will draw external dust into the air duct 3, and then into the riser 1. Since the first motor is installed in the protective shell, the dust can be prevented from directly acting on the first motor. When the dust enters the riser 1, since the riser 1 is provided with a vertical cylinder 11, and there is a distance between the vertical cylinder 11 and the riser 1, the dust will flow upward along the frustum surface at the bottom of the vertical cylinder 11, and gradually flow to between the vertical cylinder 11 and the riser 1, and then the dust will follow the airflow through the air inlet 14 into different dust removal chambers 22, and the spray assembly in the dust removal chamber 22 will spray the dust flowing through. When the dust is fully in contact with the atomized water droplets, the dust particles will combine with the water droplets to form larger particle clusters under the action of inertial collision, interception, diffusion, and condensation, and then settle into the annular bin 32 under the action of gravity. The purified gas will be discharged through the air outlet 15 and then discharged through the top of the riser 1.

[0022] By providing multiple dust removal chambers 22, the dust gas entering the riser 1 can be diverted, and the dust can be diverted to different dust removal chambers 22, and then the diverted dust can be respectively reduced by the spray components. In this process, the dust can be dispersed to prevent the dust from gathering together, resulting in excessive dust density. When reducing the concentrated dust, the atomized water droplets cannot fully contact the dust, causing some dust to be discharged into the external environment again, thereby reducing the dust removal effect. At the same time, dust with excessive density is more likely to adhere to the spray component, causing the spray component to be blocked. When the dust removal work is completed, the electric push rod 27 is controlled to retract. The retracted electric push rod 27 will drive the cylinder 24 and the rectangular cylinder 25 to move downward through the third annular plate 26. The downwardly moving cylinder 24 and the rectangular cylinder 25 will respectively drive the slide plate 23 and the first annular plate 13 to move downward. In the process of the first annular plate 13 moving downward, the space between the vertical cylinder 11 and the vertical pipe 1 will be scraped, thereby pushing the residual dust to move downward. In the process of the slide plate 23 moving downward, the dust removal chamber 22 can be scraped, thereby pushing the residual dust to move downward. When the slide plate 23 moves down to the initial position, the slide plate 23 will continue to be controlled to move downward. The downwardly moving slide 23 will continue to push the dust downward, and at the same time the first annular plate 13 will continue to move downward and gradually move down to the position below the vertical cylinder 11. When the slide 23 moves above the annular bin 32, the dust will be pushed into the annular bin 32. At the same time, the dust between the vertical cylinder 11 and the vertical pipe 1 will be pushed down and fall into the rectangular bin 34. Then the slide 23 and the first annular plate 13 are controlled to move upward and return to the initial state; that is, the slide 23 is above the air inlet 14, and the first annular plate 13 is below the air inlet 14, so that the air inlet 14 can be blocked by the first annular plate 13. During this process, the air inlet 14 is blocked by using the first annular plate 13, which can prevent external dust from entering the riser 1 through the air duct 3, and then entering the dust removal chamber 22 through the air inlet 14 and adhering to the spray assembly, gradually blocking the nozzle 41, resulting in an air flow short circuit in the subsequent dust removal process, causing the dust concentration in the exhaust gas to exceed the standard and fail to meet the environmental emission standards. At the same time, by using the slide plate 23 and the first annular plate 13 to scrape the dust in the dust removal chamber 22 and between the riser 1 and the vertical cylinder 11, the residual dust can be pushed out, avoiding the increase of residual dust in the dust removal chamber 22 and the vertical cylinder 11, which will increase the risk of clogging the spray assembly.

[0023] Since multiple spacers 33 are fixedly connected in the annular bin 32, and the spacers 33 correspond to the partitions 21 one by one and fit together, it is possible to prevent different dust removal chambers 22 from being connected, and to prevent dust in different dust removal chambers 22 from entering other dust removal chambers 22 through the annular bin 32.

[0024] As an embodiment of the present invention, the spray assembly includes a turntable 4; in the dust removal chamber 22, a plurality of circular grooves are provided in the inner wall of the annular partition 2; the turntable 4 is rotatably connected in each of the circular grooves; A cylindrical groove is formed in the middle of the rotary disc 4, and a nozzle 41 is installed in the cylindrical groove; the nozzle 41 is parallel to the dust removal chamber 22 in the initial state; The outer ring surface of the turntable 4 is fixedly connected with evenly arranged gear teeth 42, and the gear teeth 42 are made of rubber material and fit into the circular groove; The surface of the slide plate 23 that contacts the annular spacer 2 is provided with evenly arranged tooth grooves 43, and the tooth grooves 43 mesh with the gear teeth 42; A movable groove is provided on the left side of the circular groove; a hose is installed on the nozzle 41, and the hose extends into the movable groove; a plurality of liquid tanks 44 are provided on the outside of the annular partition 2, and the liquid tanks 44 are all installed on the fixed ring 35 through vertical rods; the liquid tanks 44 are connected to the external water source; and the hoses are connected to the corresponding liquid tanks 44; In this embodiment, each of the hoses is equipped with an intelligent flow meter 45, which is connected to a computer via a communication module, and the computer monitors the value changes of the intelligent flow meter 45; control valves are installed in the air inlet 14 and the air outlet 15; In this embodiment, an inclined groove 46 is provided in the inner wall of the annular partition 2 below the nozzle 41 , and the inclined groove 46 is connected to the nozzle 41 in the initial state; the inclined groove 46 is connected to the annular chamber 32 through a connecting pipe.

[0025] Since the outer ring of the turntable 4 is fixedly connected with the gear teeth 42 made of rubber material, when the slide plate 23 is pulled up by the cylinder 24, the tooth grooves 43 opened on the slide plate 23 will gradually come into contact with the gear teeth 42. In the process of the slide plate 23 passing the turntable 4, the turntable 4 will gradually drive the turntable 4 to rotate, and the rotating turntable 4 will drive the nozzle 41 to rotate. After the slide plate 23 passes the turntable 4, the turntable 4 rotates ninety degrees and makes the nozzle 41 point to the dust removal chamber 22 and be perpendicular to the dust removal chamber 22. When the dust enters the dust removal chamber 22, the atomized water droplets sprayed by the nozzle 41 will Dust reduction: When the dust reduction is completed, the cylinder 24 will push the slide plate 23 to gradually return to its initial state. During the downward movement of the slide plate 23, when the slide plate 23 passes the turntable 4, it will push the turntable 4 to rotate in the opposite direction again. The turntable 4 rotating in the opposite direction will gradually turn into the circular groove and gradually return to its initial state. During this process, when the nozzle 41 is not in use, the nozzle 41 can be turned into the circular groove. Since the gear 42 fits the circular groove, the circular groove can be blocked to prevent dust from adhering to the nozzle 41 through the circular groove, further reducing the probability of clogging of the nozzle 41. At the same time, since the nozzle 41 is provided with an inclined groove 46 below, and the inclined groove 46 is connected to the annular bin 32 through the connecting pipe, when the nozzle 41 returns to the initial state, the nozzle 41 is controlled to continue to spray water. During the process of the nozzle 41 spraying water, the dust at the nozzle opening of the nozzle 41 can be sprayed off, and then the dust will flow out through the inclined groove 46 and flow into the annular bin 32. In this process, it can be prevented that the dust adhering to the nozzle 41 cannot be removed, causing the dust to dry on the nozzle 41 and cause the nozzle 41 to be blocked. During the implementation process, since an intelligent flow meter 45 is installed on the hose connected to the nozzle 41, and the intelligent flow meter 45 is connected to the computer through a communication module, the value changes on the intelligent flow meter 45 when the liquid passes through can be monitored by the computer. If the value on a certain intelligent flow meter 45 does not change for a long time, it can be determined that the nozzle 41 connected to the intelligent flow meter 45 is blocked. At this time, the control valves in the air inlet 14 and the air outlet 15 in the dust removal chamber 22 where the nozzle 41 is located are controlled to be closed, so that dust cannot enter the dust removal chamber 22 through the air inlet 14, so the dust removal chamber 22 is in a closed state. In this process, the dust removal chamber 22 with the blocked nozzle 41 can be closed, thereby avoiding the use of the dust removal chamber 22 with the blocked nozzle 41 to reduce dust, resulting in the inability to effectively remove dust, so that part of the dust is still discharged into the external environment. By setting a control valve, when the wet dust collector is not in use, the control valve is closed to prevent the dust in the riser 1 from entering the dust removal chamber 22.

[0026] As an embodiment of the present invention, a liquid cavity 261 is provided in the third annular plate 26, and the liquid cavity 261 is communicated with the cylinder 24 and the rectangular cylinder 25 respectively; the liquid cavity 261 is communicated with an external water source.

[0027] A liquid tank is provided in the slide plate 23; a liquid tank is also provided in the first annular plate 13; a flow channel 28 is provided at the bottom of the slide plate 23; The bottom of the first annular plate 13 is also provided with evenly arranged flow channels 28 .

[0028] In this embodiment, a baffle 29 is hinged to the bottom of the slide 23 via a torsion spring and a rotating shaft, and the baffle 29 is initially in contact with the slide 23 and seals the flow channel 28. The bottom of the first annular plate 13 is also hinged with evenly arranged baffles 29 via a torsion spring and a rotating shaft. In the initial state, the baffles 29 are in contact with the first annular plate 13 and seal the flow channel 28 .

[0029] In the process of controlling the slide plate 23 and the first annular plate 13 to move downward, water is introduced into the liquid cavity 261 of the third annular plate 26, and the water flows into the liquid grooves of the first annular plate 13 and the slide plate 23 through the cylinder 24 and the rectangular cylinder 25 respectively. Then, the water in the slide plate 23 and the first annular plate 13 flows out through the flow channel 28 respectively. The water flowing out of the slide plate 23 acts on the dust removal cavity 22, thereby cleaning the dust removal cavity 22. The water carries the scraped dust into the annular bin 32. The water flowing out of the first annular plate 13 acts on the space between the vertical cylinder 11 and the vertical pipe 1, thereby cleaning the interior of the vertical pipe 1 and the surface of the vertical cylinder 11. Then, the water carries the scraped dust into the rectangular bin 34. Since the slide 23 and the flow channel 28 on the first annular plate 13 are both fitted together by the torsion spring baffle 29, when dust passes through the flow channel 28, the baffle 29 blocks the flow channel 28, thereby preventing dust from entering the flow channel 28. When water is sprayed from the flow channel 28, the baffle 29 will be pushed open, and then the water will move down along the baffle 29 and take away the dust.

[0030] As an embodiment of the present invention; a second motor is installed in the vertical cylinder 11; a conical block 16 rotates at the bottom of the vertical cylinder 11; the conical block 16 fits with the bottom of the vertical cylinder 11; The outer ring of the conical block 16 is fixedly connected to uniformly arranged scrapers 17, and the scrapers 17 extend to the truncated cone at the bottom of the vertical cylinder 11; the scrapers 17 are located on the inner ring of the first annular plate 13 and do not intersect with the first annular plate 13; In this embodiment, a circular ring 18 is fixedly connected to the top of the vertical pipe 1; the rectangular tubes 25 all pass through the circular ring 18 and are slidably connected to the circular ring 18; a filter screen 19 is installed in the circular ring 18.

[0031] Since there is a rotating conical block 16 at the bottom of the vertical cylinder 11, when dust enters the vertical pipe 1, it will flow along the conical block 16, thereby reducing the obstruction to the dust. When the first annular plate 13 pushes the dust downward, the second motor is controlled to drive the conical block 16 to rotate. The conical block 16 will drive the scraper 17 to rotate along the circular table surface at the bottom of the vertical cylinder 11, thereby scraping off the dust on the circular table surface of the vertical cylinder 11; Since the filter screen 19 is provided on the top of the standpipe 1 , when the gas flowing out of the gas outlet 15 still contains some dust, the filter screen 19 can be used to filter the dust again.
