Description

Technical Field

[0001] This invention belongs to the field of dust collection technology, specifically a mobile dust collection device for aluminum ingot production. Background Technology

[0002] During the aluminum ingot smelting and casting processes, a large amount of dust containing alumina, oil mist, and high-temperature fumes is generated. If not collected and treated in a timely manner, this will not only pollute the workshop environment but also endanger the health of operators. Currently, the industry mostly uses mobile dust collection equipment to collect and purify the aforementioned dust on-site. This type of equipment has advantages such as flexible deployment and no need for complex piping networks, making it suitable for multi-station, mobile operation scenarios.

[0003] However, the flue gas generated during aluminum ingot production is at a high temperature, and after the oil mist and sticky alumina dust enter the filtration device, the oil mist and water vapor easily adhere to the filter material surface to form a dense film layer when they encounter cold. Ordinary pulse cleaning methods cannot completely remove it, which can easily cause the filter material to clog quickly, increase the operating resistance of the equipment, reduce the suction, and require frequent shutdowns for manual disassembly and cleaning or replacement of the filter material, resulting in a large amount of maintenance work and high operating costs.

[0004] Therefore, the present invention provides a mobile dust collection device for aluminum ingot production. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

The purification box is equipped with a wire mesh inside and an air jet box on the top of the purification box. A processing box with a cavity is slidably mounted on the wire mesh. The processing box is open at one end facing the wire mesh. A cleaning roller is rotatably mounted inside the processing box. The cleaning roller is provided with multiple sets of bristles. A cleaning brush is rotatably mounted inside the processing box. The cleaning brush is located directly below the cleaning roller. Multiple toothed combs are rotatably mounted on the cleaning brush, and the multiple toothed combs are connected to the cleaning brush through elastic tubes. Both the cleaning roller and the comb are hollow and have multiple drainage holes. The processing box is equipped with a liquid delivery component to deliver the cleaning liquid into the cleaning brush and the cleaning roller. The rotation of the cleaning brush and the cleaning roller is controlled by a power component.

[0007] The liquid delivery assembly includes a water pump, a liquid box, an inlet pipe, an outlet pipe, and a diversion pipe. The liquid box is fixedly installed inside the treatment box and located below the cleaning brush. The water pump is mounted on the treatment box. One end of the inlet pipe is connected to the input end of the water pump, and the other end of the inlet pipe extends into the interior of the liquid box. One end of the outlet pipe is connected to the output end of the water pump, and the other end of the outlet pipe extends into the interior of the cleaning roller. One end of the diversion pipe is connected to the outlet pipe, and the other end is connected to the cleaning brush.

[0008] A partition plate is fixedly installed inside the liquid box. The liquid inlet pipe is located below the partition plate. A connecting block with a cavity is rotatably installed on the liquid box. Multiple cleaning brushes are provided. The multiple cleaning brushes are arranged in a ring at equal intervals on the connecting block, and the inner cavities of the multiple cleaning brushes are all connected to the inner cavity of the connecting block. One end of the diversion pipe extends into the interior of the connecting block.

[0009] The cleaning brush has a transmission rod rotatably mounted inside via a torsion spring. The toothed comb is fixedly mounted on the outer wall of the transmission rod. Multiple toothed combs are provided, and all of the multiple toothed combs are fixedly mounted on the outer wall of the transmission rod.

[0010] A positioning ring is fixedly installed on the side wall of the liquid box. The positioning ring has a first gear group and a second gear group inside. A control block is fixedly installed at one end of the transmission rod. The control block has a transmission gear that meshes with the first gear group and the second gear group fixedly installed through a connecting rod.

[0011] A ratchet is fixedly installed on the transmission rod, a ratchet is rotatably installed inside the cleaning brush, a slide bar is elastically installed inside the cleaning brush, the slide bar is connected to the ratchet via a fixed rod, an elastic strip for pushing the slide bar is sleeved on the outer wall of the control block, and multiple push rods for pressing the elastic strip are elastically installed inside the control block.

[0012] The control block has a rotating block rotatably mounted inside, and an arc-shaped block for pushing the push rod is fixedly mounted on the outer wall of the rotating block. The cleaning brush has a push rod elastically mounted inside, and a spiral groove is opened inside the rotating block. A guide block is fixedly mounted on the outer wall of the push rod. One end of the push rod passes through the transmission gear and is movably connected to the transmission gear. The positioning ring has a positioning groove inside for the push rod to slide, and an inclined stop block for pressing the push rod to slide is fixedly installed inside the positioning groove.

[0013] The beneficial effects of this invention are as follows: 1. The present invention discloses a mobile dust collection device for aluminum ingot production. This invention rapidly cools high-temperature exhaust gas containing oil mist and sticky dust by spraying cold air at an angle towards the wire mesh through a jet box. This causes the oil mist to condense into small droplets, while the wire mesh efficiently captures the condensed oil droplets and sticky dust, allowing them to agglomerate and fall off by gravity. This achieves pre-separation of oil mist and sticky dust, preventing them from entering subsequent filter media and forming an adhesive film. This significantly reduces the equipment's operating resistance and maintains stable suction. The processing box can slide along the wire mesh, and its internal cleaning rollers drive brushes to promptly clean residual oil mist from the wire mesh surface, further preventing wire mesh blockage. This reduces the frequency of manual disassembly and cleaning, and filter replacement, lowering maintenance workload and operating costs, ensuring continuous and stable equipment operation, and adapting to the multi-station, mobile operation requirements of aluminum ingot production.

[0014] 2. The mobile dust collection device for aluminum ingot production described in this invention can accurately deliver cleaning fluid into the cleaning roller and cleaning brush through a liquid delivery component. When the cleaning roller rotates, the cleaning fluid is sprayed onto the wire mesh through the drain hole, which, together with the brush bristles, enhances the cleaning effect of the wire mesh. The comb on the cleaning brush can comb and clean the bristles of the cleaning roller, while simultaneously spraying cleaning fluid through the drain hole to thoroughly remove oil droplets adhering to the surface of the bristles. The comb can rotate 180° back and forth. When it enters the liquid box under the drive of the cleaning brush, it can achieve thorough cleaning by means of water flow resistance and its own oscillation, ensuring a continuous and stable cleaning effect. There is no need for manual cleaning of the bristles and wire mesh, further improving the automation level of the equipment, extending the service life of components such as the wire mesh and cleaning roller, and reducing the long-term operating cost of the equipment.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] A mobile dust collection device for aluminum ingot production, as described in this embodiment of the invention, includes a dust collection device 1, an air inlet pipe 2, and an exhaust pipe 3; The dust collection device 1 has a purification box 4 connected to the air inlet pipe 2 inside. The purification box 4 has a wire mesh 5 inside and an air jet box 6 on the top of the purification box 4. When the exhaust gas produced during aluminum ingot production is sent into the inner cavity of the purification chamber 4 through the air inlet pipe 2, cold air is first sprayed at an angle towards the wire mesh 5 through the air jet box 6 to cool the exhaust gas entering the inner cavity of the purification chamber 4. This causes the oil mist in the exhaust gas to change from a gaseous state to a liquid state, forming small droplets. When the exhaust gas containing droplets passes through the wire mesh 5, the wire mesh 5 captures these condensed oil droplets and sticky dust, causing them to aggregate on the surface of the wire mesh 5 and fall off by gravity. This achieves pre-separation of oil mist and sticky dust, preventing them from entering the subsequent filter material and forming an adhesive film that causes blockage. This reduces the operating resistance of the equipment and the frequency of manual maintenance.

[0020] A processing box 7 with a cavity is slidably installed on the screen 5. The processing box 7 is open at one end facing the screen 5. A cleaning roller 8 is rotatably installed inside the processing box 7. The cleaning roller 8 is provided with multiple sets of bristles. The treatment box 7 is attached to the surface of the wire mesh 5. The treatment box 7 can be slidably installed inside the purification box 4 by a common electric push rod. When the treatment box 7 slides along the surface of the wire mesh 5, the cleaning roller 8 drives the bristles to clean the oil mist remaining on the surface of the wire mesh 5.

[0021] A cleaning brush 14 is rotatably mounted inside the treatment box 7. The cleaning brush 14 is located directly below the cleaning roller 8. Multiple toothed combs 19 are rotatably mounted on the cleaning brush 14. The multiple toothed combs 19 are connected to the cleaning brush 14 through the elastic tube 20. The comb 19 can rotate 180° on the cleaning brush 14. Through the elastic tube 20, it can still maintain communication with the cleaning brush 14 when the comb 19 rotates. When the cleaning brush 14 rotates, the comb 19 can comb and clean the bristles on the cleaning roller 8, and remove the oil droplets adhering to the surface of the bristles.

[0022] Both the cleaning roller 8 and the toothed comb 19 are hollow. Both the cleaning roller 8 and the toothed comb 19 have multiple drainage holes 10. The processing box 7 is equipped with a liquid delivery component to deliver the cleaning liquid into the cleaning brush 14 and the cleaning roller 8. The rotation of the cleaning brush 14 and the cleaning roller 8 is controlled by a power component.

[0023] The power unit consists of a pulley set driven by a motor, which connects the cleaning roller 8 and the cleaning brush 14 in series. The motor drives the cleaning roller 8 and the cleaning brush 14 to rotate counterclockwise simultaneously through the pulley set. When the cleaning roller 8 and the cleaning brush 14 rotate at the same time, the cleaning brush 14 located below can clean the cleaning roller 8.

[0024] Simultaneously, the cleaning fluid is delivered into the cleaning roller 8 and the cleaning brush 14 in conjunction with the liquid delivery component. At this time, while the rotating cleaning roller 8 is cleaning the screen 5, the drain hole 10 on the cleaning roller 8 can spray the cleaning fluid onto the screen 5, thereby assisting the cleaning roller 8 in cleaning the screen 5. When cleaning the bristles, the comb 19 on the cleaning brush 14 can also spray the cleaning fluid through the drain hole 10 on the comb 19, which facilitates the improvement of the cleaning effect on the bristles.

[0025] Since both the cleaning roller 8 and the cleaning brush 14 drain water when rotating, an identical treatment box 7 can be set on the other side of the wire mesh 5 to wrap both sides of the wire mesh 5 and reduce the leakage of cleaning liquid. Alternatively, a baffle can be set at the corresponding position on the other side of the treatment box 7 to prevent the cleaning liquid from spilling out.

[0026] The liquid delivery assembly includes a water pump 11, a liquid box 9, an inlet pipe 12, an outlet pipe 13, and a diversion pipe 38. The liquid box 9 is fixedly installed inside the treatment box 7 and located below the cleaning brush 14. The water pump 11 is installed on the treatment box 7. One end of the inlet pipe 12 is connected to the input end of the water pump 11, and the other end of the inlet pipe 12 extends into the interior of the liquid box 9. One end of the outlet pipe 13 is connected to the output end of the water pump 11, and the other end of the outlet pipe 13 extends into the interior of the cleaning roller 8. One end of the diversion pipe 38 is connected to the outlet pipe 13, and the other end is connected to the cleaning brush 14.

[0027] When the water pump 11 starts, it draws out the cleaning fluid from inside the liquid box 9 through the inlet pipe 12 and sends it into the cleaning roller 8 through the outlet pipe 13. The cleaning fluid inside the outlet pipe 13 is then sent into the cleaning brush 14 through the diversion pipe 38.

[0028] A partition plate 15 is fixedly installed inside the liquid box 9. The liquid inlet pipe 12 is located below the partition plate 15. A connecting block 17 with a cavity is rotatably installed on the liquid box 9. Multiple cleaning brushes 14 are provided. The multiple cleaning brushes 14 are arranged in a ring at equal intervals on the connecting block 17, and the inner cavities of the multiple cleaning brushes 14 are all connected to the inner cavity of the connecting block 17. One end of the diversion pipe 38 extends into the interior of the connecting block 17.

[0029] The connecting block 17 is connected to the pulley assembly. When the motor rotates, it can drive the connecting block 17 to rotate. The connecting block 17 can drive multiple cleaning brushes 14 to rotate simultaneously, thereby improving the cleaning effect on the cleaning roller 8. The diversion pipe 38 will send the liquid into the inner cavity of the connecting block 17, and finally it will flow evenly into the interior of multiple cleaning brushes 14.

[0030] The partition plate 15 can block and filter the oil droplets cleaned by the cleaning roller 8 by the cleaning brush 14, so that the cleaning liquid falling into the bottom of the liquid box 9 can maintain the standard of recycling.

[0031] The cleaning brush 14 has a transmission rod 16 mounted inside by a torsion spring. The toothed comb 19 is fixedly mounted on the outer wall of the transmission rod 16. Multiple toothed combs 19 are provided, and all of them are fixedly mounted on the outer wall of the transmission rod 16.

[0032] The transmission rod 16 drives the cleaning brush 14 to rotate synchronously. The transmission rod 16 can only rotate 180° back and forth on the inner wall of the cleaning brush 14. At the same time, it can also make the comb 19 rotate 180° back and forth. When the cleaning brush 14 comes into contact with the bristles on the cleaning roller 8 and rotates into the liquid box 9, the cleaning liquid inside the liquid box 9 will soak and clean the comb 19. At the same time, as the connecting block 17 drives the cleaning brush 14 to rotate, the comb 19 can move in the cleaning liquid. The resistance of the water flow can be used to improve the cleaning effect. At the same time, the transmission rod 16 drives the comb 19 to rotate 180°, flipping the comb 19 and rotating the side close to the bristles of the cleaning roller 8 to the position close to the partition plate 15. At this time, the connecting block 17 drives the cleaning brush 14 to rotate. Since the side of the comb 19 with oil droplets is currently facing down and is not obstructed, the cleaning effect of the comb 19 by the resistance of the water flow will be better.

[0033] A positioning ring 18 is fixedly installed on the side wall of the liquid box 9. The positioning ring 18 has a first gear set 23 and a second gear set 24 inside. A control block 27 is fixedly installed at one end of the transmission rod 16. The control block 27 has a transmission gear 21 that meshes with the first gear set 23 and the second gear set 24 fixedly installed through the connecting rod 26.

[0034] The first tooth group 23 is composed of intermittent tooth blocks, with one tooth block missing between every three tooth blocks. Therefore, when the transmission rod 16 has elastic potential energy, it will cause the transmission gear 21 to have elastic potential energy. The first tooth group 23 is located at the bottom of the positioning ring 18. When the transmission gear 21 meshes with the first tooth group 23, as the cleaning brush 14 drives the transmission gear 21 to rotate, the transmission gear 21 will rotate and immediately return to its original position. This allows the transmission gear 21 to drive the transmission rod 16 to maintain a small range of oscillation and control the comb 19 to oscillate within a small range. Therefore, when the cleaning brush 14 drives the comb 19 to rotate to the bottom of the liquid box 9, the setting of the first tooth group 23 allows the transmission gear 21 to drive the transmission rod 16 to keep the comb 19 horizontal and maintain a small range of oscillation. By oscillating in the water, the cleaning effect of the comb 19 is improved.

[0035] The second gear group 24 is a regionally dense combination of gear blocks. When the transmission gear 21 rotates to this area, it will perform a complete transmission and control the transmission gear 21 to rotate 180° at this point.

[0036] A ratchet 34 is fixedly installed on the transmission rod 16. A ratchet 35 is rotatably installed inside the cleaning brush 14. A slide bar 36 is elastically installed inside the cleaning brush 14. The slide bar 36 is connected to the ratchet 35 through a fixed rod 37. An elastic strip 33 for pushing the slide bar 36 is sleeved on the outer wall of the control block 27. Multiple push rods 32 for pressing the elastic strip 33 are elastically installed inside the control block 27.

[0037] By restricting the transmission rod 16 through the ratchet 34 and ratchet 35, the transmission rod 16 cannot drive the ratchet 34 to rotate clockwise.

[0038] The elastic strip 33 is sleeved on the farthest end of the multiple push rods 32. When one of the push rods 32 slides away from the control block 27, it will push the elastic strip 33 to deform. Due to the large deformation range of the elastic strip 33, the slide rod 36 is pushed to slide, and the ratchet 35 is controlled to release the obstruction of the ratchet 34. When the transmission gear 21 slides to the area of ​​the first gear set 23, it can achieve the effect of reciprocating swing by cooperating with the elastically set transmission rod 16.

[0039] A rotating block 28 is rotatably mounted inside the control block 27. An arc-shaped block 31 for pushing the push rod 32 is fixedly mounted on the outer wall of the rotating block 28. A push rod 39 is elastically mounted inside the cleaning brush 14. A spiral groove 29 is opened inside the rotating block 28. A guide block 30 is fixedly mounted on the outer wall of the push rod 39. By sliding the push rod 39 toward the position of the rotating block 28, and by sliding the guide block 30 inside the spiral groove 29, the rotating block 28 and the arc block 31 can be driven to push the push rod 32. The single arc block 31, together with multiple push rods 32, can easily control the push rod 32 to push the elastic strip 33 and contact the ratchet 35 to control the ratchet 34 when the control block 27 is rotated to any position.

[0040] One end of the push rod 39 passes through the transmission gear 21 and is movably connected to the transmission gear 21. The positioning ring 18 has a positioning groove 25 for the push rod 39 to slide inside. An inclined stop 22 for pressing the push rod 39 to slide is fixedly installed inside the positioning groove 25.

[0041] The inclined stop 22 extends to the end of the first gear set 23. When the transmission gear 21 drives the push rod 39 to the position of the inclined stop 22, the push rod 39 can be pushed into the interior of the rotating block 28 through the inclined surface. It will slide inside the spiral groove 29 through the guide block 30, which can drive the rotating block 28 and the arc block 31 to push the push rod 32. When the inclined stop 22 moves out of the range of the first gear set 23, the push rod 39 is reset. It slides inside the spiral groove 29 through the guide block 30, which drives the rotating block 28 and the arc block 31 to release the push rod 32, so that the ratchet 35 blocks the ratchet 34 again.

[0042] At the same time, when sliding to the second tooth group 24, since the ratchet 34 is blocked by the ratchet 35 again, the transmission gear 21 will drive the transmission rod 16 and the comb 19 to rotate 180° again, turning the comb 19 back to facilitate cleaning of the bristles.
