Description

Technical Field

[0001] The invention belongs to the technical field of coal mine ventilation, and in particular relates to ventilation and purification equipment for a coal mine excavation working face. Background Art

[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly peel off the surface soil layer to mine coal. This is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. In order to ensure the ventilation effect of the excavation face and reduce the harm of gas and coal dust to workers, ventilation and purification equipment is usually used to discharge the air inside the coal mine to the outside.

[0003] In the Chinese patent with publication number CN218687516U, a coal mine ventilation air purification device is mentioned, which is provided with a rotating motor to drive the rotating fan blades to rotate and inhale the external air through the high-density filter plate, the porous filter plate and the filter square plate to perform multi-stage filtering operations on the dust and particles in the air, so that the dust and particles in the air have a better filtering effect, can better ensure the convenience of dust and particle filtering, and help to better use;

[0004] However, the cleaning process of the ventilation and purification equipment requires manual removal of the filter, which not only increases the operating burden of the workers and increases labor costs, but may also accelerate the wear of the filter due to frequent disassembly and assembly processes and increase the frequency of replacement. The equipment must be shut down during the cleaning of the filter, which directly leads to the interruption of the ventilation and purification process. It may not only affect the air quality of the excavation face and increase the risk of workers being exposed to harmful dust and gases, but may also disrupt the overall production rhythm due to shutdowns and reduce coal mining efficiency.

[0021] (1) The present invention sets a purification mechanism at the top of the dust removal box. The air extracted through the diversion pipe is input into one of the purification cylinders, so that the air can be filtered and purified through multiple purification filters in turn. At the same time, the flow of air drives the driving fan to rotate, thereby driving the cleaning brush in the other purification cylinder to clean the purification filter.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1:

[0040] See also Figures 1 to 8 As shown, a ventilation and purification device for a coal mine excavation working face comprises:

[0041] Dust removal box 1;

[0042] A purification mechanism 2 is installed at the top of the dust removal box 1, and shunt pipes 3 are installed at both ends of the purification mechanism 2. Adjustment mechanisms 4 are installed on the opposite sides of the two shunt pipes 3. A transmission mechanism 5 is installed inside the dust removal box 1.

[0043] The purification mechanism 2 includes a purification cylinder 21, a cleaning mechanism 22, a fixing frame 23, a purification filter 24, an ultraviolet lamp 25 and a dust hopper 26. There are two purification cylinders 21, two cleaning mechanisms 22 and two ultraviolet lamps 25. The two purification cylinders 21 are installed on the opposite sides of the two diversion pipes 3, and the two cleaning mechanisms 22 are installed between the opposite sides of the two purification cylinders 21. There are several fixing frames 23, purification filters 24 and dust hoppers 26. Several fixing frames 23 are respectively installed on the inner walls of the two purification cylinders 21, and several purification filters 24 are respectively installed on the inner walls of several fixing frames 23. Two ultraviolet lamps 25 are respectively installed at one end of the rightmost fixing frame 23, and several dust hoppers 26 are respectively installed at the bottom ends of the two purification cylinders 21. The bottom ends of several dust hoppers 26 are all installed on the top of the dust removal box 1.

[0044] Depend on Figures 1 to 3 It can be seen that the cleaning mechanism 22 includes a protective box 221, a cleaning shaft 222, a cleaning brush 223, a pulley group 224, a driving shaft 225 and a driving fan 226. The protective box 221 is installed between the opposite surfaces of the two purification cylinders 21, the cleaning shaft 222 is installed on one end of the protective box 221 through a bearing, a plurality of cleaning brushes 223 are provided, and the plurality of cleaning brushes 223 are installed on the outer surface of the cleaning shaft 222, the driving shaft 225 is installed on the other end of the protective box 221 through a bearing, the pulley group 224 is installed between the outer surfaces of the cleaning shaft 222 and the driving shaft 225, and the other end of the driving shaft 225 is installed with a driving fan 226.

[0045] As can be seen from the above, during the use of the ventilation and purification equipment, the corresponding valves on the two shunt pipes 3 can be selectively closed or opened by the controller 6 to control the air flow to one of the purification cylinders 21. The air is filtered and purified through multiple purification filters 24 in turn, and the air purification effect is enhanced by the ring-shaped ultraviolet lamp 25 and the corresponding photocatalyst filter on its fixing frame 23. Effective air purification significantly reduces the concentration of dust and harmful gases in the air, providing a healthier and safer working environment for miners. At the same time, the air flow drives the driving fan 226 and the pulley group 224 to rotate. , which in turn drives the cleaning shaft 222 and the cleaning brush 223 in the other purification cylinder 21 to rotate, and automatically cleans the purification filter 24. In this way, the two purification cylinders 21 can alternately perform air purification and filter cleaning without stopping for cleaning, thereby ensuring the stability of the air quality at the excavation face and the continuity of ventilation purification, reducing the risk of workers being exposed to harmful dust and gases, and improving excavation work efficiency. In addition, the design of the automatic cleaning filter reduces the need for manual cleaning, reduces labor intensity and labor costs, improves work efficiency and safety, and at the same time reduces the wear and replacement frequency of the purification filter 24.

[0046] Specifically, refer to Figures 1 to 3 As shown, the bristles of the cleaning brush 223 are in contact with the mesh surface of the purification filter 24, valves are provided on the lower part of the outer surface of the dust hopper 26 and on both sides of the outer surface of the diversion pipe 3, and several dust hoppers 26 are respectively located at the lower left of several corresponding fixing frames 23, and the diversion pipe 3 is set as a Y-shaped structure.

[0047] As can be seen from the above, it is ensured that the cleaning brush 223 can effectively contact the mesh surface of the purification filter 24 for brushing and cleaning. The valve can control the switching state of the dust hopper 26 and the diverter pipe 3 to ensure that the dust cleaned by each purification filter 24 can be smoothly discharged through the corresponding dust hopper 26 to avoid dust accumulation inside the equipment. The Y-shaped diverter pipe 3 can divide the air into two paths to realize air diversion processing.

[0048] Embodiment 2:

[0049] refer to Figure 4 and Figure 5 As shown, the adjustment mechanism 4 includes a ventilating tube 41, a mounting frame 42, a mounting hole 43, a connecting screw 44 and a disassembling tube 45. The ventilating tube 41 is mounted on the other end of the shunt pipe 3. Two mounting frames 42 are provided. The two mounting frames 42 are respectively mounted on both sides of the outer surface of the ventilating tube 41. Four mounting holes 43 are provided. The four mounting holes 43 are respectively opened at the top ends of the two mounting frames 42. The connecting screw 44 is provided on one side of the interior of the ventilating tube 41. The disassembling tube 45 is installed inside the ventilating tube 41 through the connecting screw 44.

[0050] A speed regulating fan 46 is installed on one side of the inner wall of the disassembly cylinder 45, a connecting screw groove 47 is opened on one side of the outer surface of the disassembly cylinder 45, a dust sensor 48 is installed on the other side of the inner wall of the disassembly cylinder 45, and a processor 49 is installed on one end of the dust sensor 48.

[0051] As can be seen from the above, first, the mounting frame 42 near the shunt pipe 3 is installed and fixed in the coal mine. Then, through the folding pipe designed on the ventilation tube 41, the length of the ventilation tube 41 can be flexibly adjusted, and another mounting frame 42 is also installed and fixed in the coal mine to meet different usage requirements. At this time, the speed-adjustable fan 46 starts to draw the air in the coal mine into the ventilation tube 41, and then the air is diverted to the purification mechanism 2 through the shunt pipe 3 for purification. At the same time, the dust sensor 48 can detect the dust concentration in the air in real time and transmit the signal to the processor 4. 9. The processor 49 controls the rotation speed of the speed-regulating fan 46 according to the received signal to adjust the ventilation volume and the air purification effect. Through the intelligent adjustment of the dust sensor 48 and the speed-regulating fan 46, the ventilation volume can be flexibly adjusted according to the actual situation, so as to achieve more refined management and reduce the energy consumption of the equipment. In addition, when it is necessary to inspect or clean the components in the disassembly cylinder 45, the protrusion of the disassembly cylinder 45 can be grasped and rotated, and the disassembly cylinder 45 can be easily removed from the ventilation cylinder 41 through the connection relationship between the connecting screw groove 47 and the connecting screw strip 44.

[0052] Preferably, reference Figure 4 and Figure 5 As shown, the disassembly tube 45 is set to a T-shaped structure, the processor 49 is electrically connected to the dust sensor 48 and the speed-regulating fan 46, and the middle part of the ventilation tube 41 adopts a folded pipe design.

[0053] As can be seen from the above, the T-shaped disassembly tube 45 can be easily installed or disassembled with the ventilation tube 41, realizing signal transmission and control between the dust sensor 48, the speed regulating fan 46 and the processor 49, and the folding pipe design allows the ventilation tube 41 to be flexibly extended and retracted.

[0054] Embodiment three:

[0055] refer to Figures 6 to 8 As shown, a controller 6 is installed in the middle of the outer surface of the dust removal box 1, a protective cover 7 is installed at the bottom end of the dust removal box 1, a water inlet pipe 8 is installed on one side of the top of the dust removal box 1, and a water outlet pipe 9 is installed on the lower side of one end of the dust removal box 1;

[0056] The transmission mechanism 5 includes a transmission rod 51, a worm 52, a stirring mechanism 53, a transmission wheel set 54 and a driver 55. Two transmission rods 51 are provided, and the two transmission rods 51 are installed between the inner walls of both sides of the protective cover 7 through bearings. There are a plurality of worms 52 and stirring mechanisms 53, and the plurality of worms 52 are respectively installed on the outer surfaces of the two transmission rods 51, and the plurality of stirring mechanisms 53 are installed inside the dust removal box 1. The transmission wheel set 54 is installed between the outer surfaces of the two transmission rods 51, and the driver 55 is installed at one end of the transmission rod 51 on one side.

[0057] The stirring mechanism 53 includes a stirring rod 531, a transmission blade 532, a stirring paddle 533 and a worm gear 534. The stirring rod 531 is installed on the bottom inner wall of the protective cover 7 through a bearing, the transmission blade 532 is installed on the upper outer surface of the stirring rod 531, the stirring paddle 533 is installed in the middle of the outer surface of the stirring rod 531, and the worm gear 534 is installed in the lower outer surface of the stirring rod 531.

[0058] As can be seen from the above, during the automatic cleaning process of one of the purification cylinders 21, the controller 6 opens the valves on the corresponding dust hoppers 26, so that the cleaned dust can smoothly enter the interior of the dust removal box 1 through the dust hoppers 26. At the same time, the controller 6 controls the driver 55 to start, and realizes the synchronous rotation of the two transmission rods 51 through the transmission of the transmission wheel group 54. The two transmission rods 51 drive the several worm gears 52 thereon to rotate together. At this time, through the precise engagement between the worm gear 52 and the corresponding worm wheel 534, the stirring rod 531 is driven to rotate, and then the transmission blades 532 and the stirring paddle 533 thereon are driven to rotate. In this process, the transmission blades 532 transport the dust in the dust hopper 26 to the water inside the dust removal box 1 to ensure the smooth discharge of dust, while the stirring paddle 533 stirs the dust and water to make them fully mixed and evenly mixed, thereby preventing dust particles from flying into the air again and avoiding the problem of secondary dust pollution.

[0059] Preferably, reference Figures 6 to 8 As shown, the upper portion of the outer surface of the transmission blade 532 is located inside the dust hopper 26 and does not contact each other. The transmission blade 532 is configured as a spiral structure, the worm gear 534 is meshed with the corresponding worm 52, and the driver 55 is electrically connected to the controller 6.

[0060] As can be seen from the above, when the transmission blade 532 rotates inside the dust hopper 26, the dust can be transmitted from the bottom of the dust hopper 26 to the inside of the dust removal box 1. The spiral structure transmission blade 532 facilitates the smooth transmission of dust and can convert the rotational motion of the worm 52 into the rotational motion of the worm wheel 534, thereby realizing signal transmission and control between the driver 55 and the controller 6.

[0061] Application examples:

[0062] This design is applied in the environment of the excavation face in the coal mine. The excavation face is an important part of the coal mining process. It involves the excavation of lanes or tunnels. In this process, a large amount of dust and harmful gases, such as coal dust and methane, will be generated. These dust and gases will not only pose a serious threat to the health of miners (such as pneumoconiosis, gas explosion, etc.), but also affect the safety and efficiency of coal mine production. Specifically, the excavation face is usually located deep underground, with relatively small space and insufficient light. Due to the crushing of coal seams and rocks, a large amount of dust and debris will be generated. Therefore, in this environment, effective ventilation and air purification are the key to ensuring the safety and health of miners and improving production efficiency.

[0063] The present design sets a purification mechanism 2 and a shunt pipe 3 so that the shunt pipe 3 inputs air into one of the purification cylinders 21. When one purification cylinder 21 performs air purification, the other purification cylinder 21 cleans the filter, so that the two purification cylinders 21 can be used alternately. In this way, the equipment can continuously purify the air without stopping, thereby improving the working efficiency. The thrust generated by the wind flow is used to drive the cleaning mechanism 22 to rotate, thereby automatically cleaning the filter. This design reduces the need for manual cleaning and reduces the labor intensity of the staff. Then, by setting an adjustment mechanism 4, the length of the ventilation cylinder 41 can be flexibly adjusted, and the dust sensor 48 therein can sense the dust concentration in the air in real time, and the speed of the speed-regulating fan 46 can be flexibly adjusted according to the concentration change. In this way, the ventilation volume can be adjusted according to the actual situation to achieve a better air purification effect. Finally, by setting a transmission mechanism 5, the dust is transmitted to the water in the dust removal box 1, and stirred to make it fully mixed, so that the dust can be effectively removed from the air to prevent it from flying again and causing pollution.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
