Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, and more specifically, to an eco-friendly dust removal device for furniture processing. Background Technology

[0002] Furniture refers to all kinds of items used in daily life. During its processing, due to the inherent properties of wood, the cutting process often generates a large amount of scattered wood chips. Some of these wood chips are small and lightweight, making them easily suspended in the air by air currents, thus causing a significant impact on the surrounding ecological environment.

[0003] Current dust removal typically uses baghouse vacuum cleaners, which use cloth bags as the filter medium to capture and collect dust, particulate matter, and other impurities. After prolonged operation, a large amount of dust gradually accumulates on the surface of the cloth bags, affecting the suction effect. Although existing technologies clean the cloth bags by blowing air in reverse, this process requires stopping the vacuum cleaner's suction, affecting the continuity of dust removal operations.

[0004] Meanwhile, dust that detaches from the bag surface during reverse air cleaning easily disperses and adheres to the inside of the vacuum cleaner. Once the machine is restarted for vacuuming, this dust will re-adhere to the bag. If a dedicated cleaning of the vacuum cleaner's interior is required, it must be stopped again, impacting overall work efficiency.

[0005] In view of this, we propose an eco-friendly dust removal device for furniture processing. Summary of the Invention

[0017] Beneficial effects Compared with the prior art, the present invention provides an eco-friendly dust removal device for furniture processing, which has the following beneficial effects: 1.

[0019] 3. By setting an adjustment mechanism, when the metal filter shell becomes increasingly clogged, the invention automatically drives the limiting component to release the limit by utilizing the change in negative pressure, causing the entire metal filter shell to move upward and changing the relative position of the air intake pipe and the metal filter shell.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0025] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0026] This invention provides an eco-friendly dust removal device for furniture manufacturing processes, such as... Figures 1-5 As shown, it includes: support leg 1, fixed shell 2, air outlet pipe 3, connecting shell 4, connecting ring 5, rotating part 1 6, air inlet pipe 7, fixed plate 8, sealing sleeve 9, rotating part 2 10, metal filter shell 11, bottom shell 12, drive mechanism and adjustment mechanism. The support leg 1 is fixedly connected to a fixed shell 2. An air outlet pipe 3 is fixedly connected to and connected to one side of the fixed shell 2. A connecting shell 4 is detachably connected to the top of the fixed shell 2. A rotating component 6 is detachably connected to the connecting shell 4. An air inlet pipe 7 is rotatably connected to the middle of the rotating component 6. A fixed plate 8 is fixedly connected to a connecting ring 5 and is fixedly connected to the air inlet pipe 7. A sealing sleeve 9 is slidably connected to the bottom of the fixed shell 2. A rotating component 10 is rotatably connected to the sealing sleeve 9. A metal filter shell 11 is slidably connected inside the fixed shell 2. The metal filter shell 11 is connected to the rotating component 10. The rotating component 10 is splined and bolted together; the inlet pipe 7 and outlet pipe 3 are located on the inner and outer sides of the metal filter housing 11, respectively; the inlet pipe 7 is fixedly connected to an elastic cleaning plate 101, which abuts against the metal filter housing 11; the bottom shell 12 is rotatably connected to the lower side of the rotating component 10; the drive mechanism is located on the connecting shell 4, and the drive mechanism changes the rotation speed of the rotating component 16 according to the pressure in the outlet pipe 3; the adjustment mechanism is located on the fixed shell 2, and the adjustment mechanism changes the position of the metal filter housing 11. In use, an external air pump is connected to the air outlet pipe 3, and then the air inlet pipe 7 is extended to the area to be suctioned. The air pump on the air outlet pipe 3 is started, and a negative pressure is generated in the air outlet pipe 3 and the fixed shell 2, which in turn draws the generated wood chips and dust into the air inlet pipe 7. Under the guidance of the air inlet pipe 7, the airflow carries the wood chips and dust to impact the metal filter shell 11. Under the filtering action of the metal filter shell 11, the wood chips and dust in the air are filtered, and then the filtered air is discharged through the air outlet pipe 3.

[0027] Under the action of the drive mechanism, the metal filter shell 11 rotates circumferentially within the fixed shell 2. The metal filter shell 11 drives the rotating part 10 to rotate along the sealing sleeve 9. During the rotation of the metal filter shell 11, the wood chips and dust on the metal filter shell 11 move away from the air outlet pipe 3 and the air inlet pipe 7. Then, under the action of the elastic cleaning plate 101, the wood chips and dust fall into the bottom shell 12. The wood chips and dust in the bottom shell 12 are then cleaned and recycled periodically.

[0028] When the metal filter housing 11 becomes clogged, the position of the metal filter housing 11 is changed by the adjustment mechanism, thereby changing the relative position of the air intake pipe 7 and the metal filter housing 11, thus ensuring the filtration efficiency of wood chips and dust.

[0029] like Figure 4 , Figures 6-8 As shown, the drive mechanism includes: a vertical rod 13, a rubber ring 14, a slide rail 15, a motor 16, a frustum wheel 17, a fixed seat 18, a worm gear 19, a gear 20, a rack 21, a support frame 22, a worm 23, a fixed ring 24, a torsion spring 25, a winding wheel 26, a fixed tube 27, a piston 28, and a connecting rope 29. Multiple vertical rods 13 are provided, all of which are fixed to the lower side of the rotating component 6. The vertical rods 13 are slidably connected to the metal filter shell 11. A rubber ring 14 is sleeved and fixedly connected to the rotating component 6. A slide rail 15 is fixedly connected to the connecting shell 4. The slide rail 15 is slidably connected to a motor 16 through a connecting seat. The output shaft of the motor 16 is fixedly connected to a frustum wheel 17. The frustum wheel 17 and the rubber ring 14 abut against each other. One generatrix of the frustum wheel 17 is parallel to the direction of gravity. A fixed seat 18 is fixedly connected to the connecting shell 4. The fixed seat 18 is rotatably connected to a worm gear 19 and a gear 20. The worm gear 19 and the gear 20 are rotatably connected to each other. The motor 16 is fixedly connected to a rack 21, which meshes with a gear 20. A support frame 22 is fixedly connected to a fixed base 18. A worm 23 is rotatably connected to the support frame 22 and meshes with a worm wheel 19. A fixed ring 24 is fixedly connected to the worm 23. A torsion spring 25 is fixedly connected between the fixed ring 24 and the support frame 22. A winding wheel 26 is fixedly connected to the worm 23. The exhaust pipe 3 is fixedly connected to and connected to a fixed pipe 27. A piston 28 is slidably connected inside the fixed pipe 27. A connecting rope 29 is fixedly connected to and wound around the winding wheel 26. The connecting rope 29 is fixedly connected to the piston 28.

[0030] When in use, the motor 16 is started, and the output shaft of the motor 16 drives the frustum wheel 17 to rotate circumferentially. The frustum wheel 17 drives the rubber ring 14 and the rotating part 6 to rotate circumferentially through friction. The rotating part 6 drives the metal filter shell 11 to rotate circumferentially through the vertical rod 13. The metal filter shell 11 drives the rotating part 10 to rotate circumferentially along the sealing sleeve 9. During the above process, the metal filter shell 11 rotates circumferentially, so that the wood chips and dust are evenly distributed on the inner wall of the metal filter shell 11, and the elastic cleaning plate 101 cleans the wood chips and dust on the metal filter shell 11.

[0031] When the metal filter housing 11 becomes clogged, the pressure inside the outlet pipe 3 is lower than the external pressure. Under the pressure, the piston 28 slides downward along the fixed pipe 27. The piston 28 pulls the winding wheel 26 to rotate through the connecting rope 29. The winding wheel 26 drives the worm 23 to rotate. The worm 23 rotates along the support frame 22. The worm 23 drives the worm wheel 19 to rotate. The worm 23 drives the fixed ring 24 to rotate. The torsion spring 25 is tightened. The worm wheel 19 drives the gear 20 to rotate. The gear 20 drives the rack 21 to move upward, causing the motor 16 and the frustum wheel 17 to move upward. This changes the transmission ratio between the frustum wheel 17 and the rubber ring 14, thereby increasing the rotation speed of the rotating part 6 and increasing the rotation speed of the metal filter housing 11. This prevents sawdust and dust from accumulating too thickly on the inner wall of the metal filter housing 11, which would affect the suction efficiency of the inlet pipe 7 in the suction area.

[0032] like Figure 2 , Figure 9 and Figure 10 As shown, the adjustment mechanism includes: guide rod 30, ring 31, sliding rod 32, spring 1 33, limit block 34, support plate 35, limit plate 36, driving component 37, fixing block 38, fixing tube 2 39, piston 2 40, support ring 41, spring 2 42 and connecting rod 43. Multiple guide rods 30 are provided, all of which are slidably connected to the lower side of the fixed shell 2. The guide rods 30 are fixedly connected to the sealing sleeve 9. A ring 31 is fixedly connected to the lower side of the multiple guide rods 30. A sliding rod 32 is slidably connected to the fixed shell 2. The sliding rod 32 is fixedly connected to the ring 31. A spring 33 is fixedly connected between the sliding rod 32 and the fixed shell 2. A limiting component is provided between the fixed shell 2 and the air outlet pipe 3, and the limiting component limits the guide rods 30. Multiple limiting blocks 34 are provided, and the multiple limiting blocks 34 are fixedly connected to the guide rods 30 at equal intervals. A support plate 35 is fixedly connected to the fixed shell 2, and the support plate 35 is slidably connected to the guide rods 30. There are two limiting plates 36; the driving component 37 is rotatably connected to the support plate 35, and the driving component 37 has two sets of through slots. The ends of the limiting plates 36 slide in the through slots of the driving component 37; the driving component 37 is fixedly connected to a fixing block 38, and the fixing block 38 has a through slot. The air outlet pipe 3 is fixedly connected to and connected to a second fixing pipe 39. A second piston 40 is slidably connected in the second fixing pipe 39. A support ring 41 is fixedly connected in the second fixing pipe 39. A second spring 42 is fixedly connected between the support ring 41 and the second piston 40; the second piston 40 is fixedly connected to a connecting rod 43, and the lower end of the connecting rod 43 slides in the through slot of the fixing block 38 through a connecting piece.

[0033] After piston 28 stops moving, worm gear 23 stops rotating, motor 16 stops moving downward along slide rail 15. As the air pump works, and the filter holes of metal filter housing 11 are not cleaned, if the negative pressure in the exhaust pipe 3 continues to increase, the external pressure will push piston 40 upward, spring 42 will be compressed, and piston 40 will pull fixed block 38 upward through connecting rod 43. Fixed block 38 will drive drive component 37 to rotate along support plate 35. During the rotation, the two limiting plates 36 move in opposite directions. In the initial state, the lower limiting plate 36 is positioned relative to limiting block 34. When the two limiting plates 36 move in opposite directions, the lower limiting plate 36 loses contact with the limiting block 34, and the upper limiting plate 36 has moved above the limiting block 34. Under the elastic force of the spring 33, the sliding rod 32 moves upward along the fixed shell 2. The sliding rod 32 drives the guide rod 30 to slide upward along the fixed shell 2 through the ring 31. The guide rod 30 drives the metal filter shell 11 to move upward through the sealing sleeve 9 and the rotating part 10, changing the relative position of the air inlet pipe 7 and the air outlet pipe 3 with the metal filter shell 11. The metal filter shell 11 slides along the vertical rod 13.

[0034] When the metal filter housing 11 undergoes relative displacement, the negative pressure in the air outlet pipe 3 is released. Under the elastic force of the second spring 42, the second piston 40 is reset. The second piston 40 drives the driving component 37 to reset via the connecting rod 43 and the fixed block 38. When the driving component 37 resets, the two limiting plates 36 are also reset. During the reset process of the two limiting plates 36, the upper limiting plate 36 releases its restriction on the limiting block 34, and the lower limiting plate 36 restricts the fixed block 38 below it. This causes the metal filter housing 11 to move upward alternately, thereby changing the position of the metal filter housing 11 without stopping the operation.

[0035] When the metal filter housing 11 can no longer move along the fixed housing 2, disconnect the metal filter housing 11 from the rotating part 10, then remove the connecting ring 5 from the connecting housing 4, take out the metal filter housing 11, clean the filter holes of the metal filter housing 11, and reinstall the metal filter housing 11 to the initial state.

[0036] Working principle of the invention: When the device is in operation, an external air pump is first connected to the exhaust pipe 3, and the intake pipe 7 is extended to the area to be suctioned through an extension pipe. After the air pump is started, a negative pressure is generated inside the exhaust pipe 3 and the fixed housing 2. The airflow carrying sawdust and dust is sucked in through the intake pipe 7 and impacts the metal filter housing 11 under the guidance of the intake pipe 7. The metal filter housing 11 filters the sawdust and dust in the air, and the filtered clean air is discharged through the exhaust pipe 3.

[0037] During equipment operation, the drive mechanism starts, and the output shaft of motor 16 drives the frustum wheel 17 to rotate. The frustum wheel 17 drives the rubber ring 14 and the rotating component 6 to rotate through friction. The rotating component 6 drives the metal filter shell 11 to rotate circumferentially within the fixed shell 2 via the vertical rod 13. At the same time, the metal filter shell 11 drives the rotating component 10 to rotate along the sealing sleeve 9. The circumferential rotation of the metal filter shell 11 causes the sawdust and dust to be evenly distributed on its inner wall. The elastic cleaning plate 101 continuously cleans the surface of the metal filter shell 11 during rotation, causing the detached sawdust and dust to fall into the bottom shell 12. The sawdust and dust accumulate in the bottom shell 12 and will not re-adhere to the metal filter shell 11. Then, they are cleaned and recycled periodically.

[0038] When the metal filter housing 11 becomes clogged, the negative pressure inside the outlet pipe 3 increases. Under the action of air pressure, the piston 28 slides along the fixed pipe 27, pulling the winding wheel 26 to rotate via the connecting rope 29. The winding wheel 26 drives the worm 23 to rotate, which in turn drives the worm wheel 19 and gear 20 to rotate. The gear 20 drives the motor 16 and the frustum wheel 17 to move upward via the rack 21, changing the transmission ratio between the frustum wheel 17 and the rubber ring 14, increasing the rotation speed of the rotating part 6, and thus accelerating the rotation speed of the metal filter housing 11. This prevents excessive accumulation of sawdust and dust on the inner wall and ensures suction efficiency.

[0039] If the blockage in the metal filter housing 11 is not relieved in time, the negative pressure in the outlet pipe 3 continues to increase. Under the action of air pressure, piston 40 moves upward along the fixed pipe 39, compressing spring 42. Through connecting rod 43, it pulls the fixed block 38 and drive component 37 to rotate. Drive component 37 drives the two limiting plates 36 to move in opposite directions, causing the lower limiting plate 36 to disengage from the limiting block 34, and the upper limiting plate 36 to move above the limiting block 34. At this time, under the action of spring 33, sliding rod 32 drives ring 31 and guide rod 30 to slide upward. Guide rod 30 drives the metal filter housing 11 to move upward as a whole through sealing sleeve 9 and rotating component 10, changing the relative position of the inlet pipe 7 and the metal filter housing 11, and further optimizing the filtration path. After the negative pressure is released, spring 42 pushes piston 40 to reset, drive component 37 and limiting plate 36 return to their initial state, and lower limiting plate 36 re-limits the limiting block 34, realizing the alternating adjustment of the position of metal filter housing 11 during continuous operation.

[0040] When the metal filter housing 11 can no longer move along the fixed housing 2 or requires deep maintenance, disconnect the metal filter housing 11 from the rotating part 10, remove the connecting ring 5 from the connecting housing 4, take out the metal filter housing 11 and clean its filter holes. After cleaning, reinstall it to the initial state to complete the maintenance operation.

[0041] In all the solutions mentioned above, for connections between two components, welding, bolt and nut connection, bolt or screw connection, or other known connection methods can be selected according to the actual situation. These will not be elaborated here. For all fixed connections mentioned above, welding is preferred. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
