Technical Field
[0001] This utility model belongs to the field of mine dust removal technology, specifically a mine ventilation and dust removal device. Background Technology
[0002] Mines generate large amounts of dust during production, which not only harms miners' health but can also cause safety accidents such as explosions. Furthermore, dust emissions into the atmosphere pollute the environment.
[0003] With increasing environmental awareness and improved energy efficiency, the recovery and utilization of resources such as low-temperature heat energy in mine return air has gained attention. However, high dust content can easily affect heat exchange efficiency, thus requiring dust removal devices to reduce dust concentration.
[0004] However, most existing mine ventilation and dust removal devices only remove dust from the air in coal mine roadways and intake shafts, resulting in a large amount of dust in the return air shaft, thus polluting the environment. At the same time, existing dust removal devices have poor dust recovery efficiency because the dust particles are small and the dust flows back. In order to solve the above problems, this utility model designs a mine ventilation and dust removal device. Utility Model Content
[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a mine ventilation and dust removal device, which effectively solves the problems mentioned in the background art.

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] (1) This utility model uses a water pump and a solenoid valve to deliver clean water from the water tank to the nozzle through a water pipe, thereby wetting the dust inside the dust collection box, preventing the dust inside the dust collection box from flowing back, thus ensuring the dust collection effect, thus ensuring the dust removal effect of the air inside the cyclone separator, thus preventing dust from floating in the air, thus protecting the environment.
[0013] (2) The present invention allows high-speed air from inside the intake pipe to enter the cyclone separator along the tangential direction through the connector. This causes the air entering the cyclone separator to rotate along the inner wall of the cyclone separator, thereby providing a centrifugal force for the air and dust inside the cyclone separator. This allows the air that has been cleaned of dust to be discharged along the air supply pipe, while the dust rotates downward along the inner wall of the cyclone separator. The dust then enters the dust collection pipe along the separator funnel and falls into the dust collection box. At this time, the protective disc prevents the dust from flowing back, thus ensuring the dust removal effect, improving the dust removal efficiency, and ensuring the accuracy of dust removal.
[0014] (3) The present invention can drive the fan to rotate by the motor, thereby increasing the air flow rate inside the fan and thus increasing the centrifugal force inside the cyclone separator. At the same time, the device can filter large impurities in the air at the left end of the air inlet pipe through the filter plate. At the same time, the cleaning rod can extend and drive the cleaning plate to descend, thereby driving the sealing block to descend, so that the cleaning plate can clean the large impurities on the left side of the filter plate, thereby ensuring that large impurities do not enter the cyclone separator and thus ensuring the dust removal effect.

[0028] When using this device, the operator assembles the entire device. Then, the operator installs the air inlet of the blower 501 at the outlet of the return air shaft or at the air inlet of the gas pipeline in the coal mine roadway. At this time, the device can filter the air in the dust removal roadway and the air discharged from the return air shaft. The controller 101 then controls the blower 501 to operate, causing air to be transported through the connecting pipe 503 to the inside of the air inlet pipe 6. Due to the function of the filter plate 701, large impurities in the air are filtered out. Furthermore, the controller 101 controls the motor 602 to operate, thereby driving the fan 603 to rotate, thus increasing... The air inside the intake pipe 6 is rapidly drawn in, causing it to enter the cyclone separator 2 tangentially through the connector 207. At this time, the fan 603 accelerates the air inside the cyclone separator 2, causing it to rotate along the internal axis. This creates centrifugal force, causing the clean air to rotate upwards along the axis of the cyclone separator 2. Simultaneously, gravity causes dust to rotate downwards along the inner wall of the cyclone separator 2, further rotating downwards along the separator funnel 202, and falling into the dust collection pipe 203, and ultimately into the dust collection box 3. Internally, the protective disc 204 prevents dust from flowing back into the dust collection box 3. Furthermore, the controller 101 controls the water pump 401 and the solenoid valve 402 to operate, thereby delivering clean water from the water tank 4 to the nozzle 404 via the water pipe 403. This wets the dust inside the dust collection box 3, preventing backflow and ensuring effective dust removal. Meanwhile, the level sensor 302 monitors the level of wastewater inside the dust collection box 3. When the controller 101 detects a high level of wastewater inside the dust collection box 3 via the level sensor 302, the controller 101 controls the... The sewage valve 301 is opened to discharge sewage. At the same time, the controller 101 monitors the gas flow rate inside the air inlet pipe 6 through the gas flow meter 601. When the gas flow meter 601 detects that the flow rate inside the air inlet pipe 6 is low, the controller 101 controls the cleaning rod 7 to extend, thereby driving the cleaning plate 702 to descend, which in turn drives the connecting strip 703 to descend, causing the sealing block 704 to descend. This allows impurities at the left end of the filter plate 701 to fall through the cleaning chamber 706, thus preventing large impurities from entering the cyclone separator 2 and ensuring dust removal effect and efficiency.
[0029] The working process of this utility model is as follows: When using this device, the operator assembles the entire device. Then, the operator installs the air inlet of the fan 501 at the outlet of the return air shaft or at the air inlet of the gas transmission pipeline in the coal mine roadway. At this time, the device can filter the air in the dust removal roadway and the air discharged from the return air shaft. The controller 101 then controls the fan 501 to operate, causing air to be transported through the connecting pipe 503 to the inside of the air inlet pipe 6. Due to the function of the filter plate 701, large impurities in the air are filtered out. Finally, the controller 101 controls the motor 602 to operate, thereby driving the fan. The fan 603 rotates, accelerating the air inside the intake pipe 6, causing it to enter the cyclone separator 2 tangentially through the connector 207. At this time, the fan 603 causes the air inside the cyclone separator 2 to accelerate and rotate along the inside of the telescopic cyclone separator 2. The air gains centrifugal force, causing the clean air to rotate upwards along the axis of the cyclone separator 2. Simultaneously, due to gravity, dust rotates downwards along the inner wall of the cyclone separator 2, further rotating downwards along the separator funnel 202, and falling into the dust collection pipe 203, where it eventually falls into the dust collection tube. Inside the dust collection box 3, the protective disc 204 prevents dust from flowing back. Furthermore, the controller 101 controls the water pump 401 and the solenoid valve 402 to deliver clean water from the water tank 4 to the nozzle 404 via the water pipe 403, thus wetting the dust inside the dust collection box 3 and preventing backflow, thereby ensuring the dust removal effect. At this time, the liquid level sensor 302 monitors the liquid level of the wastewater inside the dust collection box 3. When the controller 101 detects a high liquid level inside the dust collection box 3 via the liquid level sensor 302, the controller 101... The controller 101 controls the sewage valve 301 to open, thereby discharging sewage. At the same time, the controller 101 can monitor the gas flow rate inside the air inlet pipe 6 through the gas flow meter 601. When the gas flow meter 601 detects that the flow rate inside the air inlet pipe 6 is small, the controller 101 controls the cleaning rod 7 to extend, thereby driving the cleaning plate 702 to descend, which in turn drives the connecting strip 703 to descend, causing the sealing block 704 to descend. This allows impurities at the left end of the filter plate 701 to fall through the cleaning chamber 706, thus preventing large impurities from entering the cyclone separator 2 and ensuring dust removal effect and efficiency.
