Description

Technical Field

[0001] This invention relates to the field of smoke and dust removal mechanisms, specifically to a smoke and dust removal mechanism for air pollution control in bio-based asphalt processing. Background Technology

[0002] Air pollution generated during asphalt production mainly comes from the heating and combustion of asphalt. Under high-temperature conditions, asphalt releases substances harmful to the natural environment and human health. Therefore, fume removal systems are primarily designed to control and reduce the fumes and harmful substances generated during asphalt processing, ensuring environmental and operational safety. The fume removal system in bio-based asphalt processing mixing units is a crucial element in achieving sustainable development. Through effective technological means, it can significantly reduce environmental pollution and operational risks.

[0003] Patent CN214389438U discloses a dust removal mechanism for a bio-based asphalt processing mixing device, including a heating cylinder and a coarse filter cylinder. A fine filter cylinder is connected above the coarse filter cylinder, and the fine filter cylinder is arranged with a negative electrode mesh, a positive electrode mesh, and a fan in sequence from the inlet to the outlet. A booster is fixedly connected to the outer wall of the fine filter cylinder. The booster is electrically connected to both the positive and negative electrode meshes. A nozzle is arranged above one side of the positive electrode mesh. In this patent, the flue gas first passes through the negative electrode mesh. The current is boosted by the booster, forming a strong electric field in the negative electrode mesh, which causes the passing fine particles to become negatively charged. The air mixed with fine particles continues to move forward along the airflow channel. When it encounters the positive electrode mesh, it is adsorbed by the positive electrode mesh. The water flow from the nozzle acts on the positive electrode mesh, washing the impurities on the positive electrode mesh into the drain pipe, and then flowing into the water tank for subsequent circulation, thus saving resources.

[0004] However, during the use of the above-mentioned device, dust will accumulate at the filter, which will affect its ventilation and subsequent dust filtration effect. Therefore, a smoke and dust removal mechanism for the prevention and control of air pollution in bio-based asphalt processing is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a dust removal mechanism for air pollution control in bio-based asphalt processing, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a dust removal mechanism for air pollution control in bio-based asphalt processing, comprising a base, a motor mounted on the top of the base, a support column fixedly connected to the top of the base, a filtration mechanism, a stirring mechanism, and a cleaning mechanism, and a primary filter cartridge fixedly connected to the top of the base. A second air inlet pipe is fixedly connected to the circumferential surface of the primary filter cartridge, a guide pipe is fixedly connected to the circumferential surface of the primary filter cartridge, and a first air inlet pipe is fixedly connected to the circumferential surface of the primary filter cartridge. The other end of the primary filter cartridge is fixedly connected to a fine filter cylinder. A fine filter cylinder cover is fixedly connected to the top of the fine filter cylinder cover. A water pump is fixedly installed on the top of the fine filter cylinder cover. An air outlet pipe is fixedly connected to the top of the fine filter cylinder cover. A water outlet pipe is fixedly connected to one side of the primary filter cylinder. A chemical dosing pipe is fixedly connected to the bottom of the water pump. The filtration mechanism includes a rotating column one, a filter disc, a triangular scraper, a squeezing block, a pushing block, a telescopic spring rod one, a fan cylinder, a rotating column two, fan blades, a sleeve block, a scraper, an arc plate, and an air inlet. The rotating column one is fixedly connected to the output end of the motor, and the filter disc is fixedly connected to the circumference of the rotating column one. The triangular scraper is fixedly connected to the inner wall of the primary filter cartridge; the extrusion block is fixedly connected to the surface of the filter disc; the first telescopic spring rod is fixedly connected to the inner wall of the primary filter cartridge; the pushing block is fixedly connected to the side of the first telescopic spring rod near the first rotating column; the fan cylinder is fixedly connected to the inner wall of the primary filter cartridge; the second rotating column is rotatably connected to the bottom of the fan cylinder; the fan blades are fixedly connected to the circumferential surface of the second rotating column; the sleeve block is fixedly connected to the circumferential surface of the second rotating column; the scraper is fixedly connected to the circumferential surface of the sleeve block; the arc-shaped plate is fixedly connected to the side of the scraper near the fan cylinder; the arc... The shaped plate slides in contact with the inner wall of the fan cylinder, the triangular scraper contacts the surface of the filter disc, the squeezing block slides in contact with the pushing block, and an air inlet is provided at the bottom of the fan cylinder. The squeezing block and the pushing block squeeze the filter disc to cause it to vibrate to a certain extent, which will cause some dust and harmful particles adhering to the surface of the filter disc to fall to the bottom of the primary filter cylinder, which facilitates the cleaning and collection of dust and harmful particles in the flue gas later, and improves the efficiency of the device. The fan blades guide the flue gas in the primary filter cylinder into the air inlet pipe, which improves the smoothness of the device and accelerates the cleaning of impurities and particles in the flue gas.

[0007] Preferably, the stirring mechanism includes a rotating column three, a connecting block, stirring blades, a stirring rod, a disc, and a telescopic spring rod two. The telescopic spring rod two is fixedly connected to the bottom of the inner cavity of the fine filter cylinder. The disc is rotatably connected to the surface of the telescopic spring rod two. The rotating column three is rotatably connected to the inner wall of the fine filter cylinder. The connecting block is fixedly connected to the circumferential surface of the rotating column three. The stirring blades are fixedly connected to the circumferential surface of the connecting block. The stirring rod is fixedly connected to the surface of the stirring blades. The stirring mechanism also includes a water inlet column, a plug, a pressing arc plate, a connecting plate, a circular nozzle, a supporting column, a bottom cover, a push column, and a connecting groove block. The water inlet column penetrates the inner wall of the fine filter cylinder cover. The plug is slidably connected to the circumferential surface of the water inlet column. The pressing arc plate is fixedly connected to the circumferential surface of the plug. The connecting plate is fixedly connected to the inner wall of the pressing arc plate. The circular nozzle... The system is fixedly connected to the inner wall of the water inlet column. The supporting cylinder is fixedly connected to the circumference of the circular nozzle. The bottom cover is fixedly connected to the side of the supporting cylinder away from the connecting plate. A motor is fixedly connected to the bottom of the fine filter cartridge. The output end of the motor is fixedly connected to the rotating column. The pushing column is fixedly connected to the bottom of the connecting plate. The bottom of the pushing column is fixedly connected to the top of the disc. The water inlet column is fixedly connected to the output end of the water pump. This system can continuously stir the liquid, allowing the chemical liquid to fully mix and contact with the particulate matter in the flue gas. This causes the impurities in the flue gas to precipitate and merge, further improving the flue gas treatment effect and reducing emissions to the environment. The connecting plate drives the pressing arc plate to move, and the pressing arc plate drives the plug cover to move down and cover the circular nozzle, so that new mixed liquid will not continue to be discharged when the liquid is discharged, reducing the waste of chemical liquid and reducing the cost of use.

[0008] Preferably, the cleaning mechanism includes a mating block, a fixing column, a long strip block, a cleaning arc plate, and an L-shaped block. The mating block is fixedly connected to the top of the disc, the fixing column is fixedly connected to the top of the disc, the long strip block is fixedly connected to the circumferential surface of the fixing column, the cleaning arc plate is fixedly connected to the side of the long strip block away from the fixing column, and the L-shaped block is fixedly connected to the inner wall of the fixing column. The cleaning mechanism also includes rollers, an inner connecting column, a collecting plate, and a baffle. The inner connecting column is rotatably connected to the top of the long strip block, the rollers are fixedly connected to both ends of the inner connecting column, the collecting plate is fixedly connected to the circumferential surface of the inner connecting column, and the baffle is fixedly connected to... On the left and right sides of the collecting plate, the cleaning arc plate is fixedly connected to the side of the L block away from the fixed column. The roller contacts the inner surface of the fine filter cartridge, and the cleaning arc plate contacts the inner wall of the fine filter cartridge. This allows the cleaning arc plate to scrape off the precipitates caused by the reaction between the chemical liquid and the dust. The precipitates adhering to the inner wall of the fine filter cartridge will flow out with the liquid through the guide pipe, increasing the service life of the device and preventing the precipitates from adhering to the inner wall of the fine filter cartridge, thus affecting the subsequent dust removal effect. When the cleaning arc plate scrapes, the collecting plate can rotate and collect the precipitates on its own surface, improving the subsequent collection efficiency of the precipitates and improving the internal cleaning effect of the fine filter cartridge.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This bio-based asphalt processing air pollution control smoke and dust removal mechanism utilizes the coordinated movement of rotating column one, filter disc, triangular scraper, extrusion block, pushing block, telescopic spring rod one, fan cylinder, rotating column two, fan blades, sleeve block, scraper, arc plate, and air inlet. The extrusion block and pushing block compress the filter disc, causing it to vibrate. This vibration dislodges dust and harmful particles adhering to the filter disc surface, causing them to fall to the bottom of the primary filter cartridge. This facilitates the subsequent cleaning and collection of dust and harmful particles from the smoke and dust, improving the device's efficiency, preventing filter disc blockage, reducing fan effectiveness, and promoting air movement inside the primary filter cartridge. The fan blades guide the smoke and dust gas from the primary filter cartridge into the air inlet pipe one, improving the device's smoothness and accelerating the removal of impurities and particles from the smoke and dust gas.

[0010] 2. This bio-based asphalt processing air pollution control smoke and dust removal mechanism utilizes the coordinated movement of a rotating column, connecting block, stirring blades, stirring rod, disc, telescopic spring rod, water inlet column, plug, pressing arc plate, connecting plate, circular nozzle, supporting column, bottom cover, pushing column, and connecting groove block. The connecting block drives the stirring blades to rotate, which in turn drives the stirring rod, continuously stirring the liquid. This ensures the chemical liquid fully mixes and contacts the particulate matter in the smoke and dust, causing impurities to precipitate and fuse, further improving the smoke and dust treatment effect and reducing environmental pollution. The connecting plate moves the pressing arc plate, which in turn moves the plug downwards, covering the circular nozzle. This prevents the discharge of new mixed liquid, reducing chemical waste and lowering operating costs.

[0011] 3. This bio-based asphalt processing air pollution control smoke and dust removal mechanism utilizes the coordinated movement of a matching block, fixed column, long strip block, cleaning arc plate, L-block, roller, inner connecting column, collection plate, and baffle. The cleaning arc plate scrapes away precipitates formed by the reaction between chemical liquid and smoke and dust. Precipitates adhering to the inner wall of the fine filter cartridge are then carried away by the liquid through the guide pipe, increasing the device's lifespan and preventing precipitates from sticking to the inner wall of the fine filter cartridge, thus affecting subsequent smoke and dust removal. During the cleaning arc plate's scraping action, the collection plate rotates, collecting precipitates on its own surface, improving subsequent precipitate collection efficiency and enhancing the internal cleaning effect of the fine filter cartridge.

Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-8One embodiment of the present invention is as follows: a dust removal mechanism for air pollution control in bio-based asphalt processing, comprising a base 15, a motor 6 mounted on the top of the base 15, a support column 13 fixedly connected to the top of the base 15, a filter mechanism 7, a stirring mechanism 8, and a cleaning mechanism 9 on the top of the base 15, a primary filter cartridge 1 fixedly connected to the top of the base 15, an air inlet pipe 14 fixedly connected to the circumference of the primary filter cartridge 1, a guide pipe 4 fixedly connected to the circumference of the primary filter cartridge 1, an air inlet pipe 5 fixedly connected to the circumference of the primary filter cartridge 1, a fine filter cartridge 3 fixedly connected to the other end of the air inlet pipe 5, a fine filter cartridge cover 12 fixedly connected to the top of the fine filter cartridge 3, and a water pump 10 fixedly mounted on the top of the fine filter cartridge cover 12. The top of the filter cylinder cover 12 is fixedly connected to an air outlet pipe 11, one side of the primary filter cylinder 1 is fixedly connected to a water outlet pipe 2, and the bottom of the water pump 10 is fixedly connected to a dosing pipe. The filtration mechanism 7 includes a rotating column 701, a filter disc 702, a triangular scraper 703, a squeezing block 704, a pushing block 705, a telescopic spring rod 706, a fan cylinder 707, a rotating column 708, a fan blade 709, a sleeve block 710, a scraper 711, an arc plate 712, and an air inlet 713. The rotating column 701 is fixedly connected to the output end of the motor 6, the filter disc 702 is fixedly connected to the circumference of the rotating column 701, the triangular scraper 703 is fixedly connected to the inner wall of the primary filter cylinder 1, the squeezing block 704 is fixedly connected to the surface of the filter disc 702, and the telescopic spring rod 706... 06 is fixedly connected to the inner wall of the primary filter cartridge 1. The push block 705 is fixedly connected to the side of the telescopic spring rod 706 near the rotating column 701. When the device is started, the dust enters the primary filter cartridge 1 through the second air inlet pipe 14. The motor 6 starts at the same time. The output end of the motor 6 drives the rotating column 701 to start rotating. The rotating column 701 drives the filter disc 702 to rotate, so that some of the dust particles stay on the surface of the filter disc 702 under the rotation of the filter disc 702, reducing some of the particles and dust in the dust. The rotation of the filter disc 702 drives the squeezing block 704 to rotate. The squeezing block 704 will contact and squeeze the push block 705 when it rotates. The squeezing block 704 and the push block 705 squeeze the filter disc 702 to a certain extent. Vibration will cause some dust and harmful particles adhering to the surface of the filter disc 702 to fall to the bottom of the primary filter cartridge 1, facilitating the subsequent cleaning and collection of dust and harmful particles in the flue gas, thus improving the efficiency of the device. The fan cylinder 707 is fixedly connected to the inner wall of the primary filter cartridge 1, the rotating column 708 is rotatably connected to the bottom of the fan cylinder 707, the fan blade 709 is fixedly connected to the circumferential surface of the rotating column 708, the sleeve block 710 is fixedly connected to the circumferential surface of the rotating column 708, the scraper 711 is fixedly connected to the circumferential surface of the sleeve block 710, the arc plate 712 is fixedly connected to the side of the scraper 711 near the fan cylinder 707, the arc plate 712 slides in contact with the inner wall of the fan cylinder 707, and the triangular scraper 703 contacts the surface of the filter disc 702.The extrusion block 704 and the push block 705 slide in contact. An air inlet 713 is provided at the bottom of the fan cylinder 707. When smoke and dust enter the primary filter cartridge 1, the rotating column 708 rotates, driving the fan blades 709 to rotate. The rotating column 708 also drives the sleeve block 710 to rotate, which in turn drives the scraper 711 to rotate. The scraper 711 then drives the arc plate 712 to rotate, continuously scraping the inner wall of the fan cylinder 707 to prevent impurities and particles from clogging the fan cylinder 707 and weakening the fan effect. This allows air to move inside the primary filter cartridge 1, and the fan blades 709 guide the smoke and dust gas in the primary filter cartridge 1 into the air inlet pipe 5, improving the smoothness of the device and accelerating the removal of impurities and particles from the smoke and dust gas.

[0016] Working Principle: When the device is started, the fumes from asphalt processing enter the primary filter cartridge 1 through the second air inlet pipe 14. Simultaneously, the motor 6 starts, and its output drives the rotating column 701 to rotate. The rotating column 701 drives the filter disc 702 to rotate, causing some of the fumes to remain on the surface of the filter disc 702, reducing the amount of particles and dust in the fumes. The rotation of the filter disc 702 also drives the extrusion block 704 to rotate. The extrusion block 704 contacts and compresses the pushing block 705. This compression causes the filter disc 702 to vibrate, dislodging some of the dust and harmful particles adhering to its surface and causing them to fall to the bottom of the primary filter cartridge 1, facilitating further cleaning. The subsequent cleaning and collection of dust and harmful particles in the smoke improves the efficiency of the device and prevents clogging of the filter. When the smoke enters the primary filter cartridge 1, the rotating column 708 rotates, which drives the fan blades 709 to rotate. The rotating column 708 also drives the sleeve block 710 to rotate, which in turn drives the scraper 711 to rotate. The scraper 711 then drives the arc plate 712 to rotate, and the arc plate 712 continuously scrapes the inner wall of the fan cylinder 707 to prevent impurities and particles from clogging the fan cylinder 707 and weakening the fan effect. This allows the air inside the primary filter cartridge 1 to move, and the smoke gas in the primary filter cartridge 1 is guided to the air inlet pipe 5 through the fan blades 709, improving the smoothness of the device and accelerating the cleaning of impurities and particles in the smoke gas.

[0017] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the stirring mechanism 8 includes a rotating column 801, a connecting block 802, a stirring blade 803, a stirring rod 804, a disc 813, and a telescopic spring rod 815. The telescopic spring rod 815 is fixedly connected to the bottom of the interior of the fine filter cartridge 3. The disc 813 is rotatably connected to the surface of the telescopic spring rod 815. The rotating column 801 is rotatably connected to the inner wall of the fine filter cartridge 3. The connecting block 802 is fixedly connected to the circumferential surface of the rotating column 801. The stirring blade 803 is fixedly connected to the circumferential surface of the connecting block 802. The stirring rod 804 is fixedly connected to the surface of the stirring blade 803. When the flue gas enters the fine filter cartridge 3 through the inlet pipe 5, the inlet pipe 5 discharges the flue gas into the fine filter cartridge. Inside the bottom area of ​​filter cartridge 3, pump 10 mixes water and chemical agents and introduces them into the inlet column 805. The mixed liquid is then discharged into the fine filter cartridge 3 through the circular nozzle 809, causing harmful substances such as sulfur dioxide in the flue gas to react. Simultaneously, the output end of the device drives the rotating column 801 to rotate, which in turn drives the connecting block 802 to rotate. The connecting block 802 drives the stirring blade 803 to rotate, which in turn drives the stirring rod 804 to rotate. This continuous stirring of the liquid ensures that the chemical liquid fully mixes and contacts the particulate matter in the flue gas, causing impurities in the flue gas to precipitate and fuse, further improving the flue gas treatment effect and reducing emissions to the environment. The stirring mechanism 8 also includes the inlet column 805, the plug 806, and the pressure arc plate 807. The system comprises a connecting plate 808, a circular nozzle 809, a supporting cylinder 810, a bottom cover 811, a push-down column 812, and a connecting groove block 814. A water inlet column 805 is connected through to the inner wall of the precision cylinder cover 12. A plug 806 is slidably connected to the circumferential surface of the water inlet column 805. A pressing arc plate 807 is fixedly connected to the circumferential surface of the plug 806. The connecting plate 808 is fixedly connected to the inner wall of the pressing arc plate 807. The circular nozzle 809 is fixedly connected to the inner wall of the water inlet column 805. The supporting cylinder 810 is fixedly connected to the circumferential surface of the circular nozzle 809. The bottom cover 811 is fixedly connected to the side of the supporting cylinder 810 away from the connecting plate 808. The push-down column 812 is fixedly connected to the bottom of the connecting plate 808, and the bottom of the push-down column 812 is fixedly connected to the top of the disc 813. The inlet column 805 is fixedly connected to the output end of the water pump 10. When the liquid reaches a certain amount, its gravity will squeeze the telescopic spring rod 815, causing the disc 813 to move downward. The movement of the disc 813 will expose the guide pipe 4. The guide pipe 4 will raise the liquid and sediment to the surface of the filter disc 702, further flushing the dust and particles on the surface of the filter disc 702. At the same time, the downward movement of the disc 813 will drive the push column 812 to move. The push column 812 will drive the connecting plate 808 to move. The connecting plate 808 will drive the pressing arc plate 807 to move. The pressing arc plate 807 will drive the plug 806 to move downward and cover the circular nozzle 809, so that new mixed liquid will not continue to be discharged when the liquid is discharged, reducing the waste of chemical liquid and reducing the cost of use.

[0018] The cleaning mechanism 9 includes a mating block 901, a fixing post 902, a long strip block 903, a cleaning arc plate 904, and an L-shaped block 909. The mating block 901 is fixedly connected to the top of the disc 813, the fixing post 902 is fixedly connected to the top of the disc 813, the long strip block 903 is fixedly connected to the circumferential surface of the fixing post 902, and the cleaning arc plate 904 is fixedly connected to the side of the long strip block 903 away from the fixing post 902. When the disc 813 moves downward, the mating block 901 moves downward and mates with the connecting groove block 814, thereby causing the connecting groove block 814 to rotate. The rotating disc 813 causes the fixed column 902 to move, which in turn moves the elongated block 903. The elongated block 903 then moves the cleaning arc plate 904, which rotates with the disc 813. This causes the cleaning arc plate 904 to scrape away the precipitates formed by the reaction between the chemical liquid and the dust. The precipitates adhering to the inner wall of the fine filter cartridge 3 are then carried away by the liquid through the guide pipe 4, increasing the lifespan of the device and preventing precipitates from adhering to the inner wall of the fine filter cartridge 3, thus affecting the subsequent dust removal effect. Block L 909 is fixedly connected to... The cleaning mechanism 9 also includes rollers 905, an inner connecting column 906, a collection plate 907, and a baffle 908 on the inner wall of the fixed column 902. The inner connecting column 906 is rotatably connected to the top of the elongated block 903. The rollers 905 are fixedly connected to both ends of the inner connecting column 906. The collection plate 907 is fixedly connected to the circumferential surface of the inner connecting column 906. The baffle 908 is fixedly connected to the left and right sides of the collection plate 907. The cleaning arc plate 904 is fixedly connected to the side of the L-block 909 away from the fixed column 902. The rollers 905 are in contact with the inner surface of the fine filter cartridge 3. The cleaning arc plate 904 contacts the inner wall of the fine filter cartridge 3. At the same time, the movement of the fixed column 902 will drive the inner connecting column 906 to move. The inner connecting column 906 drives the collecting plate 907 to move. The collecting plate 907 drives the roller 905 to move. Because the roller 905 contacts the inner wall of the fine filter cartridge 3, the roller 905 will rotate and drive the collecting plate 907 to rotate. This allows the collecting plate 907 to rotate while the cleaning arc plate 904 is scraping, and collects the precipitate on its own surface, improving the subsequent collection efficiency of the precipitate and improving the internal cleaning effect of the fine filter cartridge 3.

[0019] Working principle: When the flue gas enters the fine filter cartridge 3 through the inlet pipe 5, the inlet pipe 5 discharges the flue gas into the bottom area inside the fine filter cartridge 3. The water pump 10 mixes water and chemical agents and introduces them into the water inlet column 805. The mixed liquid is then discharged into the fine filter cartridge 3 through the circular nozzle 809, causing harmful substances such as sulfur dioxide in the flue gas to react. Simultaneously, the motor output drives the rotating column 801 to rotate, which in turn drives the connecting block 802 to rotate. The connecting block 802 drives the stirring blade 803 to rotate, which in turn drives the stirring rod 804 to rotate. This continuous stirring of the liquid ensures that the chemical liquid fully mixes and contacts the particulate matter in the flue gas, causing impurities in the flue gas to precipitate and fuse, further improving the efficiency of the filter cartridge. The dust treatment effect reduces pollution to the environment. When the liquid reaches a certain amount, its gravity will squeeze the telescopic spring rod 815, causing the disc 813 to move downward. The movement of the disc 813 will expose the guide pipe 4. The guide pipe 4 will raise the liquid and sediment to the surface of the filter disc 702, further flushing the dust and particles on the surface of the filter disc 702. At the same time, the downward movement of the disc 813 will drive the push column 812 to move. The push column 812 will drive the connecting plate 808 to move. The connecting plate 808 will drive the pressing arc plate 807 to move. The pressing arc plate 807 will drive the plug 806 to move downward and cover the circular nozzle 809, so that new mixed liquid will not continue to be discharged when the liquid is discharged, reducing the waste of chemical liquid and reducing the cost of use.

[0020] As the disc 813 moves downward, the mating block 901 moves downward and mates with the connecting groove block 814. This causes the connecting groove block 814 to rotate, driving the disc 813 to rotate. The rotation of the disc 813 then moves the fixing column 902, which in turn moves the elongated block 903. The elongated block 903 then moves the cleaning arc plate 904, which rotates with the disc 813. This allows the cleaning arc plate 904 to scrape away the precipitates formed by the reaction between the chemical liquid and the dust. The precipitates adhering to the inner wall of the fine filter cartridge 3 are then carried away by the liquid through the guide pipe 4, increasing the lifespan of the device and preventing further sedimentation. The deposits adhere to the inner wall of the fine filter cartridge 3, thus affecting the subsequent dust removal effect. At the same time, the movement of the fixed column 902 will drive the inner connecting column 906 to move, the inner connecting column 906 will drive the collecting plate 907 to move, and the collecting plate 907 will drive the roller 905 to move. Since the roller 905 is in contact with the inner wall of the fine filter cartridge 3, the roller 905 will rotate and drive the collecting plate 907 to rotate. This allows the collecting plate 907 to rotate when the cleaning arc plate 904 scrapes, and collects the deposits on its own surface, improving the subsequent collection efficiency of the deposits and improving the internal cleaning effect of the fine filter cartridge 3.
