Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mine ventilation equipment, in particular to a mine internal extraction and ventilation integrated device. BACKGROUND

[0002] In the process of coal mining, the mine usually contains harmful gases such as high-concentration gas. In order to ensure the health of construction personnel, the harmful gases in the mine need to be extracted during the construction process. At the same time, in order to ensure the oxygen concentration in the mine, fresh air needs to be transported into the mine.

[0003] Through retrieval, a mine ventilation device with publication number CN118815532B is disclosed. The device includes a casing, a ventilator, and a ventilation pipe. The ventilator is installed in the casing, and the ventilation pipe is in communication with the casing. The outer bottom side of the ventilation pipe is provided with a collection groove, which is filled with an aqueous solution. The top side of the collection groove is provided with a through groove in communication with the ventilation pipe. A sliding groove is formed in the inner wall of the ventilation pipe, and a sliding block is slidably arranged in the sliding groove. A filter screen is installed on the sliding block. A frame is installed in the ventilation pipe, and a pressure difference opening and closing spray dust removal assembly and an airflow driven dust beating assembly are fixedly arranged on the frame. The pressure difference existing in the ventilation pipe is used to realize self-cleaning of the filter screen accumulated with dust. The cleaned waste liquid can be continuously filtered, separated, and recycled, saving resource costs, and the filter screen does not need to be disassembled and cleaned or cleaned with external cleaning devices.

[0004] In the above-mentioned technology, the airflow in the ventilation pipe drives the blade to rotate, allowing the blade to beat the filter screen, thereby beating the dust intercepted on the filter screen. At the same time, high-pressure spraying is used for dust suppression. However, cleaning the filter screen in the above-mentioned way can easily cause damage to the filter screen. At the same time, the dust generated during the beating process can easily reattach to the filter screen, resulting in poor cleaning effect of the filter screen. SUMMARY

Both the second air inlet and the second air outlet are connected to the ventilation cavity.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This invention uses a water pump to deliver cleaning fluid from the water tank to the piston tube. As the amount of cleaning fluid inside the piston tube increases, the hydraulic pressure gradually increases, pushing the piston plate and piston rod to move. At this time, the first spring contracts, and the piston rod moves, causing the gate plate to move, thus opening the drain pipe so that the wastewater generated during subsequent filter cleaning can be discharged smoothly. When the piston plate passes through the inlet of the connecting pipe, the cleaning fluid flows into the guide pipe through the connecting pipe, and then into the spray pipe through the guide pipe. Finally, it is sprayed out through the nozzle of the spray pipe to rinse the filter screen.

[0024] This invention utilizes a turbine blade design that allows the cleaning fluid flowing within the water guide pipe to drive the rotating shaft and bevel gear, which in turn drives the transmission rod, synchronous pulley, and synchronous belt to rotate. This, in turn, drives the reciprocating screw to rotate. The rotation of the reciprocating screw causes the bushing to move back and forth, which in turn drives the slider and cleaning roller to move back and forth. During this reciprocating movement, the bristles on the surface of the cleaning roller can brush away impurities from the filter screen, thereby improving the cleaning effect. In addition, the movement of the cleaning roller can drive the first gear to move. Since the first gear is meshed with the rack, it can rotate during movement, thereby driving the cleaning roller to rotate. By making the cleaning roller rotate, the cleaning effect can be further improved.

[0025] This invention utilizes a top plate and top rod design. When the slider moves towards the water spray pipe, the top rod and top plate push the moving plate to move. During this process, the second spring and telescopic rod contract. Under the pressure of the moving plate, the cleaning fluid in the water storage box flows into the water spray pipe through the first water supply pipe and is sprayed out from the nozzle of the water spray pipe, thereby rinsing the cleaning roller. As the slider gradually moves away from the water spray pipe, the second spring gradually rebounds and pushes the moving plate and top plate to move. When the moving plate moves, a negative pressure is generated inside the water storage box. Under the action of the negative pressure, the cleaning fluid in the water tank flows into the water storage box through the second water supply pipe for subsequent use.

[0026] In summary, the present invention cleans the filter screen without easily causing damage, achieves good cleaning results, and allows for real-time cleaning of the cleaning roller. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Please see Figures 1-9 This invention provides an integrated extraction and ventilation device for mines, comprising a cabinet 1, a first ventilation pipe 6, a filter screen 7, a spray pipe 8, and a cleaning roller 9. The cabinet 1 is internally divided into an extraction chamber 2 and a ventilation chamber 3 by a partition. A first air inlet 4 communicating with the extraction chamber 2 is installed on the left side wall of the cabinet 1, and a first air outlet 5 communicating with the extraction chamber 2 is installed on the right side wall of the cabinet 1. The first ventilation pipe 6 is fixedly connected to one side of the extraction chamber 2 and communicates with the first air inlet 4. The filter screen 7 is detachably connected inside the first ventilation pipe 6. The spray pipe 8 is fixedly connected inside the first ventilation pipe 6 and located above the filter screen 7. The cleaning roller 9 is positioned below the filter screen 7. Both ends of the cleaning roller 9 are rotatably connected to sliders 10, which are slidably connected to the first ventilation pipe 6. Both ends of the inner wall of the first ventilation pipe 6 are rotatably connected to reciprocating screws 11, with bushings 12 sleeved in the middle of the reciprocating screws 11. The bushings 12 are fixedly connected to the sliders 10. One end of the reciprocating screws 11 extends to the outside of the first ventilation pipe 6 and is fixedly connected to a synchronous pulley 13. The two synchronous pulleys 13 are driven by a synchronous belt 14. Both ends of the cleaning roller 9 are fixedly connected to first gears 15 at positions adjacent to the sliders 10. A rack 16 is fixedly connected to the inner wall of the first ventilation pipe 6, with the rack 16 located above the first gear 15. The first gear 15 and the rack 16 are meshed together.

[0039] Specifically, by installing a pipe at the first air inlet 4 and a negative pressure fan at the first air outlet 5, harmful gases such as methane in the mine are extracted. During the extraction process, dust in the air is intercepted by the filter screen 7. After prolonged extraction operations, a large amount of dust will adhere to the surface of the filter screen 7, thus affecting the filtration efficiency. Therefore, the filter screen 7 needs to be cleaned. At this time, cleaning fluid needs to be introduced into the spray pipe 8, and the cleaning fluid is sprayed out through the nozzle of the spray pipe 8 to rinse the filter screen 7. At the same time, the two reciprocating screws 11 need to be driven to rotate. When the reciprocating screw 11 rotates, it drives the bushing 12 to reciprocate, which in turn drives the slider 10 and the cleaning roller 9 to reciprocate. During the reciprocating movement, the bristles on the surface of the cleaning roller 9 can brush away the dust on the filter screen 7, thereby improving the cleaning effect. In addition, the movement of the cleaning roller 9 can drive the first gear 15 to move. Since the first gear 15 is meshed with the rack 16, the first gear 15 can rotate when it moves, thereby driving the cleaning roller 9 to rotate. The rotation of the cleaning roller 9 can further improve the cleaning effect. A shuttle is installed inside the bushing 12. The end of the shuttle is slidably connected to the guide groove of the reciprocating screw 11. When the reciprocating screw 11 rotates, the shuttle slides along the guide groove, thereby driving the bushing 12 to reciprocate. The reciprocating movement of the bushing 12 driven by the reciprocating screw 11 is a conventional technical means, which will not be explained in detail here.

[0040] like Figure 5 , Figure 7 and Figure 9 As shown, one end of the spray pipe 8 extends to the outside of the first ventilation pipe 6 and is connected to a water guide pipe 17. A rotating shaft 18 is rotatably connected inside the water guide pipe 17. A turbine blade 19 is fixedly connected to the top of the rotating shaft 18. A transmission rod 20 is rotatably connected to the side wall of the water guide pipe 17. One end of the transmission rod 20 is fixedly connected to a synchronous pulley 13, and the other end of the transmission rod 20 and the rotating shaft 18 are both fixedly connected to bevel gears 21, which mesh with each other. A receiving hopper 22 is installed at the bottom of the first ventilation pipe 6, located below the filter screen 7. A drain pipe 23 is connected to the bottom of the receiving hopper 22. A gate 24 is slidably connected to the top of the 23; a water pump 25 is fixedly connected to the bottom of the cabinet 1, and a piston tube 26 is connected to the output end of the water pump 25. A piston plate 27 is slidably connected inside the piston tube 26. A piston rod 28 is fixedly connected to one end of the piston plate 27. The piston rod 28 is fixedly connected to the gate 24. A first spring 29 is sleeved around the piston rod 28. One end of the first spring 29 is fixedly connected to the piston plate 27, and the other end of the first spring 29 is fixedly connected to the piston tube 26. A connecting pipe 30 is connected to the end of the piston tube 26 near the drain pipe 23. The connecting pipe 30 is connected to the bottom of the water guide pipe 17.

[0041] Specifically, when cleaning fluid needs to be supplied to the spray pipe 8, the input end of the water pump 25 is connected to the cleaning fluid. The water pump 25 supplies the cleaning fluid to the piston pipe 26. As the amount of cleaning fluid inside the piston pipe 26 increases, the hydraulic pressure gradually increases, pushing the piston plate 27 and piston rod 28 to move. At this time, the first spring 29 contracts, and the piston rod 28 moves, causing the gate plate 24 to move, thus opening the drain pipe 23 to facilitate the smooth discharge of wastewater generated during subsequent cleaning of the filter screen 7. When the piston plate 27 passes through the inlet of the connecting pipe 30, the cleaning fluid flows through the connecting pipe 30 into the guide pipe 17 and then into the spray pipe 8. During the flow of the cleaning fluid in the guide pipe 17, it drives the turbine blades 19 to rotate, which in turn drives the rotating shaft 18 and bevel gear 21 to rotate, which in turn drives the transmission rod 20, synchronous pulley 13, and synchronous belt 14 to rotate, thereby driving the reciprocating screw 11 to rotate, thus providing driving force for the movement of the cleaning roller 9. When the filter screen 7 is cleaned, the water pump 25 is turned off. At this time, the hydraulic pressure in the piston tube 26 disappears, and the first spring 29 will rebound and push the piston plate 27 and piston rod 28 to move, which in turn drives the gate plate 24 to move, so that the gate plate 24 blocks the drain pipe 23 to prevent the extracted gas and other harmful gases from being discharged through the drain pipe 23.

[0042] like Figure 5 , Figure 6 and Figure 8 As shown, a water spray pipe 32 is fixedly connected inside the first ventilation pipe 6 and adjacent to the reciprocating screw 11. One end of the water spray pipe 32 is connected to a first water supply pipe 33. A water storage box 34 is fixedly connected inside the first ventilation pipe 6, located on one side of the water spray pipe 32. One end of the first water supply pipe 33 extends into the water storage box 34 and communicates with it. A first one-way valve 35 is installed on the first water supply pipe 33. A movable plate 36 is slidably connected inside the water storage box 34, and the movable plate 36 is slidably connected to the first water supply pipe 33. Two telescopic rods 38 are fixedly connected inside the water storage box 34 on the side away from the water spray pipe 32. A second spring 37 is sleeved around the telescopic rods 38. Spring 37 and telescopic rod 38 are both fixedly connected to movable plate 36. Two top plates 39 are fixedly connected to the two ends of movable plate 36 away from the second spring 37. One end of top plate 39 extends to the outside of water storage box 34 and is slidably connected to water storage box 34. Top rod 40 is fixedly connected to the bottom of slider 10. Top rod 40 is movably connected to top plate 39. Water tank 41 is fixedly connected to the cabinet 1 at the position adjacent to water pump 25. The input end of water pump 25 is connected to water tank 41. The end of water storage box 34 away from water spray pipe 32 is connected to second water supply pipe 42. One end of second water supply pipe 42 extends into the water tank 41 and is connected to water tank 41. Second one-way valve 43 is installed on second water supply pipe 42.

[0043] Specifically, the first one-way valve 35 ensures that the cleaning fluid in the water storage box 34 can only flow towards the spray pipe 32; the second one-way valve 43 ensures that the cleaning fluid in the water tank 41 can only flow towards the water storage box 34. During use, the water tank 41 needs to be filled with cleaning fluid beforehand. During the cleaning of the filter screen 7, the cleaning roller 9 needs to be driven to move back and forth to brush the filter screen 7. During this process, a lot of impurities will adhere to the surface of the cleaning roller 9, affecting subsequent cleaning. Therefore, the spray pipe 32 is used to clean the cleaning roller 9. When the slider 10 moves towards the spray pipe 32, its bottom push rod 40 contacts the top plate 39 and pushes the top plate 39 to move, thereby moving the moving plate 36. During this process, the second spring 37 and the telescopic rod 38 will contract. Under the pressure of the moving plate 36, the cleaning fluid in the water storage box 34 will flow into the spray pipe 32 through the first water supply pipe 33 and be sprayed out from the nozzle of the spray pipe 32, thus rinsing the cleaning roller 9. As the slider 10 gradually moves away from the water spray pipe 32, the second spring 37 will gradually rebound and push the moving plate 36 and the top plate 39 to move. When the moving plate 36 moves, a negative pressure will be generated inside the water storage box 34. Under the action of the negative pressure, the cleaning fluid in the water tank 41 will flow into the water storage box 34 through the second water supply pipe 42 for subsequent use.

[0044] like Figures 1 to 4 As shown, an air guide pipe 44 is connected above the first ventilation pipe 6, and a second ventilation pipe 45 is connected to one end of the air guide pipe 44. The second ventilation pipe 45 is fixedly connected to the cabinet 1 and is connected to the first air outlet 5. An activated carbon filter layer 31 is provided inside the second ventilation pipe 45. A second air outlet 46 is installed on the left side wall of the cabinet 1, and a second air inlet 47 is installed on the right side wall of the cabinet 1. Both the second air inlet 47 and the second air outlet 46 are connected to the ventilation cavity 3.

[0045] Specifically, the activated carbon filter layer 31 can further purify the extracted methane and other harmful gases, and the second air inlet 47 and the second air outlet 46 facilitate the delivery of fresh air into the mine.

[0046] Working principle: A negative pressure fan is installed at the first air outlet 5 to extract harmful gases such as methane from the mine. During the extraction process, dust in the air is intercepted by the filter screen 7. After a long period of extraction, a lot of dust will adhere to the surface of the filter screen 7, which will affect the filtration efficiency. Therefore, the filter screen 7 needs to be cleaned. At this time, the water pump 25 delivers the cleaning fluid in the water tank 41 to the piston tube 26. As the cleaning fluid inside the piston tube 26 increases, the hydraulic pressure will gradually increase, thereby pushing the piston plate 27 and the piston rod 28 to move. At this time, the first spring 29 will contract. When the piston rod 28 moves, it will drive the gate plate 24 to move, thereby opening the drain pipe 23 so that the wastewater generated during the subsequent cleaning of the filter screen 7 can be discharged smoothly. When the piston plate 27 passes through the water inlet of the connecting pipe 30, the cleaning fluid will flow into the water guide pipe 17 through the connecting pipe 30 and then into the spray pipe 8 through the water guide pipe 17. Finally, it will be sprayed out through the nozzle of the spray pipe 8 to rinse the filter screen 7.

[0047] As the cleaning fluid flows in the water pipe 17, it drives the turbine blades 19 to rotate, which in turn drives the shaft 18 and bevel gear 21 to rotate, which in turn drives the transmission rod 20, synchronous pulley 13 and synchronous belt 14 to rotate, thereby driving the reciprocating screw 11 to rotate. When the reciprocating screw 11 rotates, it drives the bushing 12 to move back and forth, which in turn drives the slider 10 and cleaning roller 9 to move back and forth. During the reciprocating movement, the bristles on the surface of the cleaning roller 9 can brush away the impurities on the filter screen 7, thereby improving the cleaning effect. In addition, during the movement of the cleaning roller 9, it can drive the first gear 15 to move. Since the first gear 15 is meshed with the rack 16, the first gear 15 can rotate when it moves, thereby driving the cleaning roller 9 to rotate. The rotation of the cleaning roller 9 can further improve the cleaning effect.

[0048] As the slider 10 moves toward the water spray pipe 32, its bottom push rod 40 contacts the top plate 39 and pushes the top plate 39 to move, thereby driving the moving plate 36 to move. During this process, the second spring 37 and the telescopic rod 38 will contract. Under the pressure of the moving plate 36, the cleaning fluid in the water storage box 34 will flow into the water spray pipe 32 through the first water supply pipe 33 and be sprayed out from the nozzle of the water spray pipe 32, thereby rinsing the cleaning roller 9. When the slider 10 gradually moves away from the water spray pipe 32, the second spring 37 will gradually rebound and push the moving plate 36. As the top plate 39 moves, the moving plate 36 generates negative pressure inside the water storage box 34. Under the action of negative pressure, the cleaning fluid in the water tank 41 flows into the water storage box 34 through the second water supply pipe 42 for subsequent use. When the filter screen 7 is cleaned, the water pump 25 is turned off. At this time, the hydraulic pressure in the piston pipe 26 disappears, and the first spring 29 will rebound and push the piston plate 27 and piston rod 28 to move, thereby driving the gate plate 24 to move, so that the gate plate 24 blocks the drain pipe 23 to prevent the extracted gas and other harmful gases from being discharged through the drain pipe 23.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
