Description

Technical Field

[0001] This invention relates to the field of air filtration technology, specifically to an air filtration device for environmental engineering. Background Technology

[0002] Air filtration devices in environmental engineering are key equipment for addressing air pollution and protecting health. They can efficiently remove dust and toxic gases from industrial waste gas, as well as pollutants such as PM2.5 and bacteria from indoor air, ensuring that emissions meet standards and reducing health risks. At the same time, they can improve production efficiency and energy utilization, and help achieve green and low-carbon development goals.

[0003] Patent CN210905429U discloses an air filtration device for environmental engineering. The air filtration device includes a base; a water tank fixedly installed on the top of the base; a sliding plate slidably installed inside the water tank, with one side extending outside the water tank; a groove formed on the top of the sliding plate; a filter screen fixedly installed on the bottom inner wall of the groove; an installation pipe fixedly installed on the top of the water tank; two annular pipes symmetrically fixedly installed inside the installation pipe; and multiple high-pressure nozzles fixedly installed on the inner side of the annular pipes. The air filtration device for environmental engineering provided by this patent has the advantages of being easy to use, having good filtration effect, and being able to filter water-soluble impurities in the air.

[0004] Because the nozzles of the above-mentioned device are fixed, uneven coverage of water mist can easily create dead zones, leading to a decrease in purification efficiency. Therefore, an air filtration device for environmental engineering 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 an air filtration device for environmental engineering, 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: an air filtration device for environmental protection engineering, comprising a housing, an air inlet cylinder fixedly connected to the circumferential surface of the housing, a cover plate fixedly connected to the top of the housing, an exhaust cylinder fixedly connected to the circumferential surface of the housing, a motor fixedly connected to the circumferential surface of the housing, a rotating shaft fixedly connected to the output end of the motor, a belt drivingly connected to the circumferential surface of the rotating shaft, a telescopic tube drivingly connected to the end of the belt away from the rotating shaft, a rotary joint rotatably connected to the circumferential surface of the telescopic tube, a support rod fixedly connected to the circumferential surface of the telescopic tube, a support shaft fixedly connected to the end of the support rod away from the telescopic tube, a roller rotatably connected to the circumferential surface of the support shaft, a protruding ring fixedly connected to the inner wall of the housing, a cleaning device provided at the bottom of the support rod, a storage box fixedly connected to the circumferential surface of the air inlet cylinder, and an air supply device provided on the inner wall of the air inlet cylinder. The telescopic tube has spray holes on its circumferential surface, and a drain pipe is fixedly connected to the circumferential surface of the housing. The circumferential surface of the telescopic tube is rotatably connected to the cover plate. The circumferential surface of the roller contacts the convex ring. A windproof cover is provided on the top of the storage box. The motor drives the rotating shaft to rotate, which in turn drives the belt drive. The belt drives the telescopic tube to rotate and spray water through the spray holes, increasing the coverage area of ​​the water mist and reducing the dead zone of the water mist. This can effectively remove dust and water-soluble pollutants from the air. The telescopic tube drives the support rod to rotate, which in turn drives the support shaft to rotate. The support shaft drives the roller to rotate. The contact and separation between the roller and the protrusion on the convex ring causes the support shaft to move up and down. The support shaft drives the support rod to move up and down, which in turn drives the telescopic tube to move up and down. This allows the water mist to be sprayed up and down, further increasing the contact area between the water mist and the air, effectively preventing dust from penetrating the water mist, and thus improving the purification efficiency.

[0007] Preferably, the cleaning device includes a connecting rod, a scraper fixedly connected to the right side of the connecting rod, a support base fixedly connected to the inner wall of the housing, a striking rod slidably connected to the inner wall of the support base, a limit block fixedly connected to the circumferential surface of the striking rod, a striking block fixedly connected to the right side of the striking rod, a top of the connecting rod fixedly connected to the support rod, and a spring provided between the support base and the limit block. Rotation of the support rod will cause the connecting rod to rotate, which in turn causes the scraper to rotate and scrape away water stains on the inner wall of the housing, preventing a mixture of water and dust from adhering to the housing. The inner wall, due to excessive accumulation of impurities, leads to increased wind resistance, which in turn reduces airflow and air purification efficiency. The deposits can also corrode the cylinder wall, causing damage to the device. The contact between the inclined surface of the scraper and the arc surface of the striking block will cause the striking block to move. The striking block will drive the striking rod to move, and the striking rod will drive the limiting block to move. The limiting block will compress the spring. When the scraper is removed, the striking block will reset due to the spring force and strike the inner wall of the shell. This can further prevent the mixture of water and dust from adhering to the inner wall of the shell and further prevent impurities from caking.

[0008] Preferably, the air supply device includes a second rotating shaft, a first bevel gear fixedly connected to the top end of the second rotating shaft, a retainer fixedly connected to the inner wall of the air inlet cylinder, a third rotating shaft rotatably connected to the inner wall of the retainer, a second bevel gear fixedly connected to the right end of the third rotating shaft, a fan fixedly connected to the circumferential surface of the third rotating shaft, a filter plate fixedly connected to the inner wall of the air inlet cylinder, the first bevel gear meshing with the second bevel gear, an external motor provided at the bottom of the air inlet cylinder, and the output end of the external motor fixedly connected to the second rotating shaft, the circumferential surface of the second rotating shaft rotatably connected to the air inlet cylinder. The air supply device also includes a fourth rotating shaft, a scraper fixedly connected to the circumferential surface of the fourth rotating shaft, a limit rod slidably connected to the inner wall of the storage box, a wedge fixedly connected to the top end of the limit rod, the circumferential surface of the fourth rotating shaft rotatably connected to the filter plate, and the wedge and... Springs are installed between the storage boxes. An external motor drives the second rotating shaft to rotate, which in turn drives the first bevel gear to rotate. The first bevel gear then drives the second bevel gear to rotate, which in turn drives the third rotating shaft to rotate. The third rotating shaft then drives the fan to rotate. The fan draws in air, and large impurities drawn in by the fan are blocked by the filter plate, preventing large impurities from getting tangled on the fan and causing it to stop working, or from entering the housing and clogging the pipes. The fan's airflow drives the scraper blades to rotate. The part of the filter plate blocked by the wind deflector does not generate wind pressure. When the scraper blades blow the impurities to the windless area, the impurities fall into the storage box, preventing impurities from adhering to the filter plate surface and reducing air purification efficiency. The fan's rotation generates vibration and causes the inclined block to shake slightly, which shakes the impurities into the storage box, effectively improving the space utilization of the storage box.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0010] 1. The air filtration device used in this environmental protection project works through the coordinated action of the housing, cover plate, motor, rotating shaft, belt, rotary joint, telescopic tube, spray nozzle, support rod, support shaft, roller, and convex ring. The belt drives the telescopic tube to rotate and spray through the spray nozzle, increasing the coverage area of ​​the water mist and reducing the dead zone of the water mist. This effectively removes dust and water-soluble pollutants from the air. The up-and-down reciprocating motion of the support rod drives the up-and-down reciprocating motion of the telescopic tube to spray vertically, further increasing the contact area between the water mist and the air. This effectively prevents dust from penetrating the water mist, thereby improving the purification efficiency.

[0011] 2. The air filtration device used in this environmental protection project, through the coordinated action of connecting rods, scrapers, support seats, striking rods, limit blocks, and striking blocks, allows the connecting rods to drive the scraper to rotate, which can scrape away water stains on the inner wall of the shell, preventing the mixture of water and dust from adhering to the inner wall of the shell. This prevents excessive accumulation of impurities from increasing wind resistance, which in turn reduces airflow and air purification efficiency. The deposits can also corrode the cylinder wall, leading to device damage. The inclined surface on the scraper contacts the arc surface of the striking block, causing the striking block to move. When the scraper moves away, the striking block will return to its original position due to spring force and strike the inner wall of the shell, further preventing the mixture of water and dust from adhering to the inner wall of the shell and further preventing impurities from caking.

[0012] 3. The air filtration device used in this environmental protection project, through the coordinated action of rotating shaft two, bevel gear one, bevel gear two, rotating shaft three, cage, fan, filter plate, rotating shaft four, scraper, inclined block, and limit rod, ensures that large impurities sucked in by the fan are blocked by the filter plate, preventing large impurities from getting tangled on the fan and causing it to stop working, or large impurities from entering the housing and clogging the pipes. The fan's airflow drives the scraper to rotate. The part of the filter plate blocked by the wind deflector does not generate wind pressure. When the scraper blows the impurities to the windless area, the impurities fall into the storage box, which can prevent impurities from adhering to the surface of the filter plate and thus reducing the air purification efficiency. The fan's rotation generates vibration and causes the inclined block to shake slightly, which can shake the impurities into the storage box, effectively improving the space utilization of the storage box.

[0020] 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.

[0021] Please see Figures 1-6One embodiment of the present invention is: an air filtration device for environmental engineering, comprising a housing 1, an air inlet 2 fixedly connected to the circumferential surface of the housing 1, a cover plate 3 fixedly connected to the top of the housing 1, an exhaust pipe 16 fixedly connected to the circumferential surface of the housing 1, a motor 4 fixedly connected to the circumferential surface of the housing 1, a rotating shaft 5 fixedly connected to the output end of the motor 4, a belt 6 drivingly connected to the circumferential surface of the rotating shaft 5, a telescopic tube 8 drivingly connected to the end of the belt 6 away from the rotating shaft 5, a rotary joint 7 rotatably connected to the circumferential surface of the telescopic tube 8, the belt 6 driving the telescopic tube 8 to rotate and spray through the spray nozzle 9, thereby increasing the coverage area of ​​the water mist, reducing the dead zone of the water mist, and effectively removing pollutants from the air. Dust and water-soluble pollutants are contained within the telescopic tube 8. A support rod 10 is fixedly connected to the circumferential surface of the telescopic tube 8. A support shaft 11 is fixedly connected to the end of the support rod 10 away from the telescopic tube 8. A roller 12 is rotatably connected to the circumferential surface of the support shaft 11. A convex ring 13 is fixedly connected to the inner wall of the housing 1. A cleaning device 14 is provided at the bottom of the support rod 10. A storage box 17 is fixedly connected to the circumferential surface of the air inlet 2. An air supply device 15 is provided on the inner wall of the air inlet 2. Spray holes 9 are opened on the circumferential surface of the telescopic tube 8. A drain pipe 18 is fixedly connected to the circumferential surface of the housing 1. The circumferential surface of the telescopic tube 8 is rotatably connected to the cover plate 3. The circumferential surface of the roller 12 contacts the convex ring 13. A windproof cover is provided on the top of the storage box 17. The support rod 10... The reciprocating motion of the telescopic tube 8 causes it to spray water up and down, further increasing the contact area between the water mist and the air. This effectively prevents dust from penetrating the water mist, thereby improving purification efficiency. The cleaning device 14 includes a connecting rod 1401, with a scraper 1402 fixedly connected to the right side of the connecting rod 1401. The connecting rod 1401 drives the scraper 1402 to rotate, which can scrape away water stains on the inner wall of the housing 1, preventing the mixture of water and dust from adhering to the inner wall of the housing 1. Excessive accumulation of impurities can increase wind resistance, leading to reduced airflow and decreased air purification efficiency. The deposits can also corrode the cylinder wall, causing damage to the device. A support base 14 is fixedly connected to the inner wall of the housing 1. 03. A striking rod 1404 is slidably connected to the inner wall of the support base 1403. A limiting block 1405 is fixedly connected to the circumferential surface of the striking rod 1404. A striking block 1406 is fixedly connected to the right side of the striking rod 1404. The top of the connecting rod 1401 is fixedly connected to the support rod 10. A spring is provided between the support base 1403 and the limiting block 1405. When the inclined surface on the scraper 1402 contacts the arc surface of the striking block 1406, it will drive the striking block 1406 to move. When the scraper 1402 is removed, the striking block 1406 will reset due to the spring force and strike the inner wall of the housing 1. This can further prevent the mixture of water and dust from adhering to the inner wall of the housing 1 and further prevent impurities from caking.

[0022] Working principle: Starting motor 4 drives shaft 5 to rotate, which in turn drives belt 6, which in turn drives telescopic tube 8 to rotate and spray water through nozzles 9. This increases the coverage area of ​​the water mist and reduces dead zones, effectively removing dust and water-soluble pollutants from the air. Telescopic tube 8 drives support rod 10 to rotate, which in turn drives support shaft 11. Support shaft 11 drives roller 12 to rotate. The contact and separation between roller 12 and the protrusion on the convex ring 13 causes support shaft 11 to move up and down, which in turn drives support rod 10 to move up and down, which in turn drives telescopic tube 8 to move up and down. This allows the water mist to spray vertically, further increasing the contact area between the water mist and the air, effectively preventing dust from penetrating the water mist and thus improving purification efficiency. The rotation of support rod 10 drives connecting rod 14. 01. Rotation causes the connecting rod 1401 to rotate the scraper 1402, which scrapes away water stains on the inner wall of the housing 1. This prevents the mixture of water and dust from adhering to the inner wall of the housing 1, thus preventing excessive accumulation of impurities, which would increase wind resistance, reduce airflow, decrease air purification efficiency, and cause the deposits to corrode the cylinder wall, potentially leading to device damage. The inclined surface on the scraper 1402 contacts the arc surface of the striking block 1406, causing the striking block 1406 to move. The striking block 1406 then moves the striking rod 1404, which in turn moves the limiting block 1405. The limiting block 1405 compresses the spring. When the scraper 1402 moves away, the striking block 1406 returns to its original position due to the spring force and strikes the inner wall of the housing 1, further preventing the mixture of water and dust from adhering to the inner wall of the housing 1 and further preventing impurities from caking.

[0023] Please see Figures 1-6Based on the above embodiments, in another embodiment of the present invention, the air supply device 15 includes a second rotating shaft 1501, a first bevel gear 1502 fixedly connected to the top end of the second rotating shaft 1501, a retainer 1505 fixedly connected to the inner wall of the air inlet cylinder 2, a third rotating shaft 1504 rotatably connected to the inner wall of the retainer 1505, a second bevel gear 1503 fixedly connected to the right end of the third rotating shaft 1504, a fan 1506 fixedly connected to the circumferential surface of the third rotating shaft 1504, and a filter plate 1507 fixedly connected to the inner wall of the air inlet cylinder 2. The first bevel gear 1502 meshes with the second bevel gear 1503, and large impurities sucked in by the fan 1506 are blocked by the filter plate 1507, preventing large impurities from getting tangled on the fan 1506 and causing the fan 1506 to stop working, or large impurities from entering the housing 1 and blocking the pipes. An external motor is provided at the bottom of the air inlet cylinder 2, and the output end of the external motor is fixedly connected to the second rotating shaft 1501. The air supply device 15 is rotatably connected to the air inlet cylinder 2. The air supply device 15 also includes a rotating shaft 1508. A scraper 1509 is fixedly connected to the circumferential surface of the rotating shaft 1508. A limit rod 1511 is slidably connected to the inner wall of the storage box 17. An inclined block 1510 is fixedly connected to the top of the limit rod 1511. The circumferential surface of the rotating shaft 1508 is rotatably connected to the filter plate 1507. A spring is provided between the inclined block 1510 and the storage box 17. The wind force of the fan 1506 will drive the scraper 1509 to rotate. The part of the filter plate 1507 blocked by the wind shield will not generate wind pressure. When the scraper 1509 scrapes the impurities to the windless area, the impurities will fall into the storage box 17, which can prevent the impurities from adsorbing on the surface of the filter plate 1507, thereby reducing the air purification efficiency. When the fan 1506 rotates, it will generate vibration and drive the inclined block 1510 to shake slightly, which can shake the impurities into the storage box 17, effectively improving the space utilization of the storage box 17.

[0024] Working principle: When the external motor is started, it drives shaft 1501 to rotate. Shaft 1501 drives bevel gear 1502 to rotate, which in turn drives bevel gear 1503 to rotate. Bevel gear 1503 drives shaft 1504 to rotate, which in turn drives fan 1506. Fan 1506 draws in air, and large impurities drawn in by fan 1506 are blocked by filter plate 1507, preventing large impurities from becoming entangled on fan 1506 and causing it to stop working. When impurities enter the housing 1 and block the pipes, the airflow from the fan 1506 will drive the scraper 1509 to rotate. The part of the filter plate 1507 blocked by the wind deflector will not generate wind pressure. When the scraper 1509 blows the impurities to the windless area, the impurities will fall into the storage box 17, which can prevent impurities from adhering to the surface of the filter plate 1507 and thus reducing the air purification efficiency. When the fan 1506 rotates, it will generate vibration and drive the inclined block 1510 to shake slightly, which can shake the impurities into the storage box 17, effectively improving the space utilization of the storage box 17.

[0025] This invention provides an air filtration device for environmental engineering. Many methods and approaches exist for implementing this technical solution; the above are merely preferred embodiments. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
