Description

Technical Field

[0001] The present invention relates to the technical field of gold mine mining, and specifically to a ventilation device for gold mine mining and its usage method. Background Art

[0002] Dust is generated during gold mine mining. The generation of dust will have an adverse impact on the working environment and the physical health of workers. Dust will reduce the visibility at the operation site and increase the accident risk. The ventilation device for gold mine mining conveys fresh air from the ground to each operation point underground through air ducts, and at the same time uses local ventilation equipment to strengthen local ventilation. The air purification equipment removes dust and harmful gases, and the ventilation structures regulate the air flow.

[0003] However, during gold mine mining, due to the large number of solid particles in the dust, it is very easy to adhere to the outer wall of the filter plate. After long-term use, there will be more impurities on the surface of the filter plate, which will reduce the filtering effect of the filter plate. At the same time, when the filtering effect of the filter plate is poor, the air flow of the ventilation device cannot be discharged, and the air flow flushes back and forth in the inner cavity of the device, which will cause the components such as the impeller and the casing of the fan to be washed and corroded by the air flow, resulting in a decline in the material performance. A ventilation device for coal mine mining (publication number CN 212039535U), in this patented technology, dust cleaning mechanisms are fixedly installed at both the left and right ends of the ventilation box. The dust cleaning mechanism includes a driving motor. The output end of the driving motor is connected to an output shaft. The middle outer side of the output shaft is connected to a mounting block. The outer side of the mounting block is connected to a positioning frame. The middle outer side of the positioning rod is connected to a limiting block. The bottom of the positioning rod is fixedly installed with a cleaning shaft. A cleaning brush is arranged at the rear side of the cleaning shaft. The rear side of the cleaning brush is connected to a filter net. It is convenient for automatic cleaning, greatly improves the work efficiency of workers, and effectively solves the problems of the prior art. However, its structure still needs to be improved, specifically as follows:

[0004] In this solution, a driving motor is used to drive the cleaning structure to operate. The driving motor will cause the device to have a high energy consumption. Since the poor environment in the mine will affect the service life of electrical equipment, the driving motor needs to be maintained regularly. Otherwise, the failure of the driving motor will cause the cleaning structure to fail. Due to the microporous structure of the filter plate adsorbing impurity particles, it is very difficult to clean the cleaning shaft and the cleaning brush sliding on the outer surface of the filter net.

[0005] Therefore, a ventilation device for gold mine mining and its usage method are needed to improve the above problems. Summary of the Invention

[0006] When the ventilation equipment for gold mine mining is in use, during gold mine mining, dust is easily adhered to the outer wall of the filter plate. After long-term use, the impurities increase, resulting in a reduction in the filtering effect. When the filtering effect is poor, the air flow of the ventilation device cannot be discharged and flushes back and forth inside the cavity, causing components such as the fan impeller and the casing to be corroded by the air flow erosion, and the material performance to decline.

[0016] As a preferred solution of the present invention, a rack is slidably connected to the inner wall of the limiting housing. One end of the rack is connected to the compression spring, and the rack is meshed with the driving gear on its outer wall. A connecting convex rod is rotatably connected to one side of the limiting housing and on the outer wall of the rack. A limiting pull rod is installed at one end of the connecting convex rod. A connecting block is rotatably connected to the outer wall of the limiting pull rod. One end of the connecting block is connected to a limiting frame.

[0017] As a preferred solution of the present invention, a protective cover is installed at the port of the fan. The controller is electrically connected to a magnetic sensor through a wire. The baffle is inclined 30 degrees relative to the inner wall of the box body. The graphene adsorption plate is located on one side of the grille plate. The diversion housing plays a role in limiting the closed plate.

[0018] A method for using a ventilation device for gold mine mining is as follows:

[0019] Operation step one: Turn on the switch of the controller so that the controller controls the fan to operate. When the fan operates, it will suck in the dust gas from the outside, and then the airflow generated by the fan enters the inner cavity of the box body. First, the airflow contacts the baffle grille, and the solid particles collide with the baffle grille and are blocked, causing the particulate matter to slide downward along the surface of the baffle grille. At this time, the particulate matter falls into the inner cavity of the installation shell along the baffle plate and is then collected in the inner cavity of the drawer. Subsequently, when the airflow passing through the baffle grille reaches the adsorption filter plate, the dust impurities are adsorbed by the adsorption filter plate, and then the filtered gas is filtered again by the subsequent graphene adsorption plate;

[0020] Operation Step 2: When the adsorption filter plate is blocked by dust and impurities, since the gas cannot pass through the adsorption filter plate, the gas in the inner cavity of the box will be flushed. At this time, the gas will flush the shunt component along the adsorption filter plate, and then the air flow will flush the sealing plate, causing the sealing plate to drive the positioning block to move under force, and then the sealing plate will drive the positioning block to rotate on the outer wall of the rotating shaft. At the same time, the sealing plate exerts a squeezing force on the limiting spring, causing the limiting spring to be compressed under force;

[0021] Operation Step 3: At the same time, the sealing plate slides and unfolds on the outer wall of the connecting rod, and then the air flow in the inner cavity of the box flows out through the shunt housing. When the opposing sealing plates at the port of the shunt housing are warped respectively, the magnetic sensor and the magnetic block will be disconnected, and then the magnetic sensor will generate an electrical signal and conduct it to the controller through the wire. When the set value is reached, the controller will display the data. When the adsorption filter plate is blocked and cannot filter, the shunt component shunts the air flow in the inner cavity of the box;

[0022] Operation Step 4: When the air flow passes through the ventilation hole, the air flow drives the impeller to rotate. When the impeller rotates, the impeller drives the connecting rod to rotate. When the connecting rod rotates, the connecting rod drives the second driving rod to rotate. When the second driving rod rotates, the second driving rod drives the driving bevel gear to rotate, and then the driving bevel gear drives the driven bevel gear to rotate through meshing connection. When the driven bevel gear rotates, the driven bevel gear drives the second rotating rod to rotate. When the second rotating rod rotates;

[0023] Operation Step 5: The other end of the second rotating rod drives the driving gear to rotate, and then the driving gear drives the rack to move horizontally through meshing connection. The rack will move to one side on the inner wall of the limiting housing. When the rack moves, the outer wall of the rack exerts a thrust on the compression spring, causing the compression spring to be compressed under force. At the same time, one end of the rack exerts a pulling force on the limiting pull rod through the connecting convex rod, and the limiting pull rod will exert a pulling force on the limiting frame through the connecting block. When the limiting frame is stressed, the limiting frame rotates around the rotating shaft, and then the limiting frame is pulled out and moved to the flapping cleaning position;

[0024] Operation Step 6: The connecting rod drives the first driving rod to rotate. When the first driving rod rotates, the first driving rod drives the driving bevel gear to operate. When the driving bevel gear rotates, the driving bevel gear drives the connecting bevel gear to operate through meshing connection. The connecting bevel gear drives the first rotating rod to rotate, and then one end of the first rotating rod drives the cam crank to rotate. Since a first rotating rod is arranged at the crank of the cam crank;

[0025] Operation step seven: When the cam crank rotates, the cam crank drives the first rotating rod to rotate, and then the first rotating rod applies a left and right rotating pulling force to the second rotating rod through the connecting plate, so that the second rotating rod applies a lateral reciprocating pulling force to the fixed handle, so that the fixed handle rotates in an arc on the outer wall of the mounting rod. Since one end of the fixed handle is connected to the flapping frame through the rotation of the fixed rod, when the fixed handle moves left and right, the fixed handle applies a reciprocating force to the flapping frame through the fixed rod. At the same time, since one end of the flapping frame applies an elastic thrust through the ejection spring, so that one end of the flapping frame always presses against the bottom of the adsorption filter plate. At this time, the other end of the adsorption filter plate is reciprocatingly flapped by the flapping frame, so that impurities and dust on the surface of the adsorption filter plate fall off, and then the dust falls into the inner cavity of the mounting shell for collection;

[0026] Operation step eight: The airflow passes through the impeller and drives the connecting rod to rotate, so that when the impeller drives the connecting rod to rotate, the connecting rod and the limit assembly are driven. When the dust on the surface of the adsorption filter plate blocks the adsorption filter plate, the airflow is discharged from the diversion assembly, thereby accelerating the operation of the impeller, and also making the cleaning assembly and the limit assembly run faster. Among them, the flapping frame in the cleaning assembly has a higher efficiency in flapping the adsorption filter plate. At this time, one end of the driving rod 2 is magnetically connected to the connecting rod. When the connecting rod rotates, the connecting rod drives the driving rod 2 to rotate through the magnetic coupling connection. When the rack moves laterally on the inner wall of the limit housing, the compression spring is compressed.

[0027] Operation step nine: When the dust on the surface of the adsorption filter plate falls off and the adsorption filter plate is filtering the gas normally, the airflow does not pass through the diversion component, and the compressed limit spring is elastically thrust to reset the sealing plate. At this time, the impeller stops running. When the impeller drives the connecting rod to stop running, the connecting rod will stop running on the cleaning component and the limit component. At this time, the compressed compression spring loses the thrust of the rack, and then the compression spring stretches and resets, so that the compression spring pushes the rack to move in the opposite direction in the limit housing. After the limit component is reset, the limit frame will also be reset.

[0028] Compared with the prior art, the present invention sets a diversion component in the gold mining ventilation equipment and its use method, so that when the adsorption filter plate is blocked by dust, the airflow in the inner cavity of the box is discharged through the diversion component, and the closed plate is forced to drive the positioning block to move, and then the closed plate drives the positioning block to rotate on the outer wall of the rotating shaft, so that the airflow in the inner cavity of the box flows out through the diversion shell. When the closed plates are tilted up respectively, the magnetic sensor and the magnetic block will be disconnected, and the magnetic sensor will generate an electrical signal which is transmitted to the controller through the wire. When the set value is reached, the controller will display the data, thereby solving the problem that when the filtering effect is poor, the airflow of the ventilation device cannot be discharged, and it is washed back and forth in the inner cavity, causing the fan impeller, casing and other components to be corroded by the airflow and the material performance to decline.

[0029] In the gold mine ventilation equipment and its usage method of the present invention, by setting a limiting component, when the connecting rod drives the second driving rod to rotate, the driving bevel gear drives the driven bevel gear to rotate through meshing connection, causing the driven bevel gear to drive the second rotating rod to rotate. The other end of the second rotating rod drives the driving gear to rotate, and then the driving gear drives the rack to move horizontally through meshing connection. One end of the rack applies a pulling force to the limiting pull rod through the connecting convex rod, causing the limiting pull rod to apply a pulling force to the limiting frame through the connecting block. When the limiting frame is stressed, it rotates around the rotating shaft, and the limiting frame is pulled out and moved to the flapping cleaning position.

[0030] In the gold mine ventilation equipment and its usage method of the present invention, by setting a cleaning component, the filter adsorption plate can be flapped to make the dust fall off. The connecting rod drives the first driving gear to drive the driving bevel gear, and the driving bevel gear drives the connecting bevel gear to operate through meshing connection, causing the cam crank to drive the first rotating rod to rotate. Then the first rotating rod applies a left - right rotating pulling force to the second rotating rod through the connecting plate, causing the fixed handle to apply a reciprocating moving force to the flapping frame through the fixed rod. At the same time, since one end of the flapping frame applies an elastic pushing force through the ejecting spring, one end of the flapping frame always abuts against the bottom of the adsorption filter plate. At this time, the other end of the adsorption filter plate is reciprocally flapped by the flapping frame, so that the impurities and dust on the surface of the adsorption filter plate fall off, and then the dust falls into the inner cavity of the installation housing for collection, thus solving the problem that in gold mine exploitation, dust is easily adhered to the outer wall of the filter plate, and the impurities increase after long - term use, resulting in a reduction in the filtering effect.

[0031] In the gold mine ventilation equipment and its usage method of the present invention, by setting multiple components to cooperate with each other and operate automatically without energy consumption. When the air flow drives the connecting rod to rotate through the impeller, the connecting rod drives the cleaning component and the limiting component. When the air flow does not pass through the shunt component, the compressed limiting spring applies an elastic pushing force to reset the sealing plate. At this time, the impeller stops rotating, and the connecting rod stops driving the cleaning component and the limiting component. At this time, the compressed spring loses the pushing force of the rack, and then the compressed spring stretches and resets, pushing the rack to displace in the reverse direction in the limiting housing. After the limiting component resets, the limiting frame also resets. The device operates automatically through the cooperation of multiple components without energy consumption, thus solving the problems that when the driving motor drives the cleaning structure to operate, the energy consumption is high, the mine environment affects its service life, and regular maintenance is required. Otherwise, the motor damage will cause the cleaning structure to fail. BRIEF DESCRIPTION OF THE DRAWINGS

The driven bevel gear 705 is meshed with the driving bevel gear 703 on its outer wall. A driving gear 706 is installed at the other end of the second rotating rod 704. A limiting housing 707 is installed on the side wall of the fixed bracket 702. A fixing block 708 is installed on the outer wall of the limiting housing 707. A compression spring 709 is installed on the side wall of the fixing block 708. A rack 710 is slidably connected to the inner wall of the limiting housing 707. The compression spring 709 is connected to the outer wall of the rack 710, and the rack 710 is meshed with the driving gear 706 on its outer wall. A connecting convex rod 711 is rotatably connected to one side of the limiting housing 707 and on the outer wall of the rack 710. A limiting pull rod 712 is installed at one end of the connecting convex rod 711. A connecting block 713 is rotatably connected to the outer wall of the limiting pull rod 712. One end of the connecting block 713 is connected to a limiting frame 19.

[0049] Under the action of the above structural features and connection relationships, one end of the second driving rod 701 is magnetically connected to the connecting rod 411. The second driving rod 701 and the connecting rod 411 are magnetically fixed through magnetic coupling connection. When the limiting component 7 drives the limiting frame 19 to be pulled out and moved to the flapping cleaning position, at this time, the rack 710 in the cavity of the limiting component 7 is stuck, and the jamming of the second driving rod 701 will not affect the rotation of the connecting rod 411;

[0050] Among them, under the action of a protective cover 23 installed at the port of the blower 11, the protective cover 23 shields the blower 11, making the device safer. Under the action of the controller 13 being electrically connected to a magnetic sensor 407 through a wire, the device is powered on, and then the controller 13 controls the magnetic sensor 407 to operate. The baffle 17 is inclined 30 degrees relative to the inner wall of the box body 2, and the graphene adsorption plate 22 is located on one side of the grille plate 12. The flow splitting housing 401 plays a role in limiting the sealing plate 404.

[0051] When the gold mining ventilation device of the present scheme and its use method are in operation, by turning on the switch of the controller 13, the controller 13 controls the fan 11 to operate. When the fan 11 is in operation, the fan 11 will suck in the dust gas from the outside, and then the airflow generated by the fan 11 will enter the inner cavity of the box body 2. First, the airflow contacts the material blocking grille 16, and the solid particles collide with the material blocking grille 16 and are blocked, causing the particles to slide downward along the surface of the material blocking grille 16. At this time, the particles fall into the inner cavity of the installation shell 3 along the material blocking plate 17 and are then collected in the inner cavity of the drawer 8. Subsequently, when the airflow passing through the material blocking grille 16 is subjected to the adsorption filter plate 20, the dust impurities are adsorbed by the adsorption filter plate 20, and then the filtered gas is filtered again by the subsequent graphene adsorption plate 22, and the filtered gas is discharged;

[0052] When the adsorption filter plate 20 is blocked by dust and impurities, the gas cannot pass through the adsorption filter plate 20, which will cause the gas in the inner cavity of the box 2 to be flushed. At this time, the gas will flush the diverter component 4 along the adsorption filter plate 20, and then the airflow will flush the sealing plate 404, so that the sealing plate 404 is forced to drive the positioning block 403 to move, and then the sealing plate 404 drives the positioning block 403 to rotate on the outer wall of the rotating shaft 402. At the same time, the sealing plate 404 applies an extruding force to the limit spring 406, so that the limit spring 406 is compressed, and the sealing plate 404 slides and expands on the outer wall of the connecting rod 411, thereby making the inner cavity of the box 2 The airflow in the cavity flows out through the diverter housing 401. When the sealing plates 404 opposite to each other at the ports of the diverter housing 401 are respectively tilted up, the magnetic sensor 407 and the magnetic block 408 are disconnected, and the magnetic sensor 407 generates an electrical signal which is transmitted to the controller 13 through a wire. When the set value is reached, the controller 13 displays the data. When the adsorption filter plate 20 is blocked and cannot filter, the diverter assembly 4 diverts the airflow in the inner cavity of the box body 2, thereby solving the problem that when the filtering effect is poor, the airflow of the ventilation device cannot be discharged, and is washed back and forth in the inner cavity, causing the fan impeller, casing and other components to be corroded by the airflow and the material performance to deteriorate.

[0053] When air flows through the ventilation hole 409, the air flow drives the impeller 410 to rotate. When the impeller 410 rotates, it causes the impeller 410 to drive the connecting rod 411 to rotate. When the connecting rod 411 rotates, it causes the connecting rod 411 to drive the second driving rod 701 to rotate. When the second driving rod 701 rotates, it causes the second driving rod 701 to drive the driving bevel gear 703 to rotate. Furthermore, the driving bevel gear 703 drives the driven bevel gear 705 to rotate through meshing connection. When the driven bevel gear 705 rotates, it causes the driven bevel gear 705 to drive the second rotating rod 704 to rotate. When the second rotating rod 704 rotates, the other end of the second rotating rod 704 drives the driving gear 706 to rotate. Furthermore, the driving gear 706 drives the rack 710 to move horizontally through meshing connection, causing the rack 710 to move to one side on the inner wall of the limiting housing 707. When the rack 710 moves, the outer wall of the rack 710 exerts a thrust on the compression spring 709, causing the compression spring 709 to be compressed under force. At the same time, one end of the rack 710 exerts a pulling force on the limiting pull rod 712 through the connecting convex rod 711, causing the limiting pull rod 712 to exert a pulling force on the limiting frame 19 through the connecting block 713. When the limiting frame 19 is stressed, the limiting frame 19 rotates around the rotating shaft 18, and thus the limiting frame 19 is pulled out and moved to the flapping and cleaning position;

[0054] The connecting rod 411 drives the first driving rod 601 to rotate. When the first driving rod 601 rotates, it drives the driving bevel gear 604 to operate. When the driving bevel gear 604 rotates, the driving bevel gear 604 drives the connecting bevel gear 606 to operate through meshing connection, and the connecting bevel gear 606 drives the first rotating rod 605 to rotate. Furthermore, one end of the first rotating rod 605 drives the cam crank 607 to rotate. Since the first rotating rod 608 is arranged at the crank of the cam crank 607, when the cam crank 607 rotates, it will drive the first rotating rod 608 to rotate. Then, the first rotating rod 608 applies a left - right rotating pulling force to the second rotating rod 611 through the connecting plate 609, so that the second rotating rod 611 applies a lateral reciprocating pulling force to the fixed handle 610, and then the fixed handle 610 rotates arcuately on the outer wall of the mounting rod 603. Since one end of the fixed handle 610 is rotatably connected to the flapping frame 613 through the fixing rod 612, when the fixed handle 610 moves left and right, the fixed handle 610 applies a reciprocating moving force to the flapping frame 613 through the fixing rod 612. At the same time, since one end of the flapping frame 613 applies an elastic pushing force through the ejecting spring 615, one end of the flapping frame 613 always abuts against the bottom of the adsorption filter plate 20. At this time, the other end of the adsorption filter plate 20 is subjected to the reciprocating flapping of the flapping frame 613, so that the impurities and dust on the surface of the adsorption filter plate 20 fall off, and then the dust falls into the inner cavity of the mounting housing 3 for collection, thus solving the problem that in gold mining, dust is easily adhered to the outer wall of the filter plate, and the impurities increase after long - term use, resulting in a reduction in the filtering effect;

[0055] The air flow drives the connecting rod 411 to rotate through the impeller 410. When the impeller 410 drives the connecting rod 411 to rotate, the connecting rod 411 will drive the cleaning component 6 and the limiting component 7. When the dust on the surface of the adsorption filter plate 20 blocks the adsorption filter plate 20, the air flow is discharged through the shunt component 4, thereby accelerating the operation of the impeller 410 and also making the cleaning component 6 and the limiting component 7 operate faster. Among them, the flapping frame 613 in the cleaning component 6 has a higher flapping efficiency for the adsorption filter plate 20. At this time, one end of the second driving rod 701 is magnetically connected to the connecting rod 411. When the connecting rod 411 rotates, the connecting rod 411 will drive the second driving rod 701 to rotate through magnetic coupling connection. When the rack 710 moves horizontally on the inner wall of the limiting housing 707, the compression spring 709 is compressed at this time. When the dust on the surface of the adsorption filter plate 20 falls off and the adsorption filter plate 20 filters gas normally, the air flow does not pass through the shunt component 4. The compressed limiting spring 406 exerts an elastic thrust to reset the sealing plate 404. At this time, the impeller 410 stops operating. When the impeller 410 drives the connecting rod 411 to stop operating, the connecting rod 411 will stop driving the cleaning component 6 and the limiting component 7. At this time, the compressed compression spring 709 loses the thrust of the rack 710, so that the compression spring 709 extends and resets, and the compression spring 709 pushes the rack 710 to displace in the opposite direction in the limiting housing 707. After the limiting component 7 is reset, the limiting frame 19 will also be reset. The device operates automatically through the cooperation of multiple components without energy consumption, thus solving the problems that the driving motor drives the cleaning structure to operate, with high energy consumption and the mine environment affecting its service life, and regular maintenance is required, otherwise the motor damage will cause the cleaning structure to fail.

6. The usage method of a ventilation device for gold mine exploitation according to claim 5, characterized in that, The steps are as follows: Operation step 1: Turn on the switch of the controller (13) so that the controller (13) controls the fan (11) to operate. When the fan (11) operates, the fan (11) will suck in the dust gas from the outside, and then the airflow generated by the fan (11) will enter the inner cavity of the box (2). First, the airflow contacts the blocking grille (16), and the solid particles collide with the blocking grille (16) and are blocked, so that the particles slide downward along the surface of the blocking grille (16). At this time, the particles fall into the inner cavity of the installation shell (3) along the blocking plate (17), and are then collected in the inner cavity of the drawer (8). Subsequently, when the airflow passing through the blocking grille (16) is subjected to the adsorption filter plate (20), the dust impurities are adsorbed by the adsorption filter plate (20), and then the filtered gas is filtered again by the subsequent graphene adsorption plate (22); Operation step 2: When the adsorption filter plate (20) is blocked by dust and impurities, the gas cannot pass through the adsorption filter plate (20), which causes the gas in the inner cavity of the box (2) to be flushed. At this time, the gas will flush the diversion component (4) along the adsorption filter plate (20), and then the airflow will flush the sealing plate (404), so that the sealing plate (404) is forced to drive the positioning block (403) to move, and then the sealing plate (404) drives the positioning block (403) to rotate on the outer wall of the rotating shaft (402), and at the same time, the sealing plate (404) applies an extrusion force to the limit spring (406), so that the limit spring (406) is compressed; Operation step three: At the same time, the sealing plate (404) slides and unfolds on the outer wall of the connecting rod (411), thereby allowing the airflow in the inner cavity of the box body (2) to flow out through the diversion shell (401). When the sealing plates (404) opposite to each other at the end of the diversion shell (401) are tilted up, the magnetic sensor (407) and the magnetic block (408) are disconnected, thereby causing the magnetic sensor (407) to generate an electrical signal which is transmitted to the controller (13) through the wire. When the set value is reached, the controller (13) will display the data. When the adsorption filter plate (20) is blocked and cannot filter, the diversion component (4) diverts the airflow in the inner cavity of the box body (2). Operation Step Four: When air flows through the ventilation holes (409), the air flow drives the impeller (410) to rotate. When the impeller (410) rotates, it drives the connecting rod (411) to rotate. When the connecting rod (411) rotates, it drives the second driving rod (701) to rotate. When the second driving rod (701) rotates, it drives the driving bevel gear (703) to rotate. Then, the driving bevel gear (703) drives the driven bevel gear (705) to rotate through meshing connection. When the driven bevel gear (705) rotates, it drives the second rotating rod (704) to rotate. When the second rotating rod (704) rotates; Operation Step Five: The other end of the second rotating rod (704) drives the driving gear (706) to rotate. Then, the driving gear (706) drives the rack (710) to move horizontally through meshing connection. The rack (710) moves to one side on the inner wall of the limiting housing (707). When the rack (710) moves, the outer wall of the rack (710) applies a thrust to the compression spring (709), causing the compression spring (709) to be compressed. At the same time, one end of the rack (710) applies a pulling force to the limiting pull rod (712) through the connecting convex rod (711). The limiting pull rod (712) applies a pulling force to the limiting frame (19) through the connecting block (713). When the limiting frame (19) is stressed, the limiting frame (19) rotates around the rotating shaft (18), and then the limiting frame (19) is pulled out and moved to the flapping and cleaning position; Operation Step Six: The connecting rod (411) drives the first driving rod (601) to rotate. When the first driving rod (601) rotates, it drives the driving bevel gear (604) to operate. When the driving bevel gear (604) rotates, it drives the connecting bevel gear (606) to operate through meshing connection. The connecting bevel gear (606) drives the first rotating rod (605) to rotate. Then, one end of the first rotating rod (605) drives the cam crank (607) to rotate. Since a first rotating rod (608) is provided at the crank of the cam crank (607); Operation Step Seven: When the cam crank (607) rotates, it will cause the cam crank (607) to drive the first rotating rod (608) to rotate. As a result, the first rotating rod (608) applies a left - right rotating pulling force to the second rotating rod (611) through the connecting plate (609), so that the second rotating rod (611) applies a transverse reciprocating pulling force to the fixed handle (610), and then the fixed handle (610) rotates in an arc on the outer wall of the mounting rod (603). Since one end of the fixed handle (610) is rotatably connected to the flapping frame (613) through the fixed rod (612), when the fixed handle (610) moves left and right, it will cause the fixed handle (610) to apply a reciprocating moving force to the flapping frame (613) through the fixed rod (612). At the same time, because one end of the flapping frame (613) applies an elastic pushing force through the ejecting spring (615), one end of the flapping frame (613) always abuts against the bottom of the adsorption filter plate (20). At this time, the other end of the adsorption filter plate (20) is reciprocally flapped by the flapping frame (613), so that the impurities and dust on the surface of the adsorption filter plate (20) fall off, and then the dust falls into the inner cavity of the installation housing (3) for collection; Operation Step Eight: When the air flow passes through the impeller (410) to drive the connecting rod (411) to rotate, when the impeller (410) drives the connecting rod (411) to rotate, the connecting rod (411) will drive the cleaning assembly (6) and the limiting assembly (7). When the dust on the surface of the adsorption filter plate (20) blocks the adsorption filter plate (20), the air flow is discharged from the shunt assembly (4), which causes the impeller (410) to operate at an accelerated speed and also makes the cleaning assembly (6) and the limiting assembly (7) operate faster. Among them, the flapping frame (613) in the cleaning assembly (6) flaps the adsorption filter plate (20) with higher efficiency. At this time, one end of the driving rod two (701) is magnetically connected to the connecting rod (411). When the connecting rod (411) rotates, it will cause the connecting rod (411) to drive the driving rod two (701) to rotate through magnetic coupling connection. When the rack (710) moves horizontally on the inner wall of the limiting housing (707), the compression spring (709) is compressed at this time; Operation Step Nine: When the dust on the surface of the adsorption filter plate (20) falls off and the adsorption filter plate (20) filters the gas normally, the air flow does not pass through the shunt assembly (4). The compressed limiting spring (406) applies an elastic pushing force to reset the sealing plate (404). At this time, the impeller (410) stops operating. When the impeller (410) drives the connecting rod (411) to stop operating, it will cause the connecting rod (411) to stop operating the cleaning assembly (6) and the limiting assembly (7). At this time, the compressed compression spring (709) loses the thrust of the rack (710), and then the compression spring (709) extends and resets, causing the compression spring (709) to push the rack (710) to displace in the opposite direction in the limiting housing (707). After the limiting assembly (7) is reset, the limiting frame (19) will also be reset.
