Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, specifically a pretreatment device for electrophoretic waste gas. Background Technology

[0002] Electrophoresis is a highly efficient industrial coating process. Its core process involves immersing the pre-treated workpiece, such as degreasing and phosphating, into an electrophoretic paint tank and connecting it to a direct current source as an electrode. This causes the charged paint particles to move directionally under the influence of the electric field and deposit on the surface of the workpiece, forming a uniform coating. The coating is then completed by washing with water and baking to cure. In the pre-treatment stage, the workpiece needs to undergo cleaning, phosphating, passivation and other processes. During this process, acid and alkali-containing mist will be generated.

[0003] Existing technologies for pre-treatment of acidic and alkaline mists often involve filtering the mist through a filter box. This filter box has a complex internal design with a labyrinthine or honeycomb structure, and also incorporates a porous filter bag, forming a multi-chamber labyrinthine layout. The working principle is as follows: when air containing acidic or alkaline mist passes through the box, the airflow changes direction multiple times within the internal baffle channels, ensuring that the mist particles fully contact the inner walls of the filter bag and filter box. This allows the mist particles to adhere to their surface, thus achieving separation of the aerosol particles from other gases.

[0004] The aforementioned technology primarily filters mist through filter boxes. However, after prolonged use, excessive mist particles accumulate inside the filter boxes, hindering the smooth passage of gas and reducing filtration efficiency. In such cases, the filter boxes need to be replaced. However, since multiple filter boxes are typically installed, replacing them one by one is slow, thus affecting maintenance efficiency.

[0005] Therefore, the present invention provides a pretreatment device for electrophoresis waste gas. Summary of the Invention

[0021] 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.

[0022] like Figures 1 to 4As shown in the embodiment of the present invention, a pretreatment device for electrophoresis waste gas includes a housing 1; an inlet pipe 2 and an exhaust pipe 3 are respectively fixedly connected to both ends of the housing 1, and an exhaust fan is installed at the exhaust pipe 3; a support plate 4 is fixedly connected inside the housing 1; through grooves 5 are provided on the top and bottom surfaces of the housing 1; sealing plates 6 are provided on the surface of the housing 1 at positions corresponding to the through grooves 5, and a counterweight is provided on the top of the sealing plate 6; a sealing ring 7 is fixedly connected to the side of the sealing plate 6 near the housing 1; a plurality of evenly arranged partitions 8 are fixedly connected to the bottom surface of the sealing plate 6; a limit plate 9 is fixedly connected to the side of the partitions 8 that are close to each other; a pair of limit plates 9 are fixedly connected to the side of the partitions 8 that are close to each other; A filter box 10 is provided between each of the position plates 9; each filter box 10 has a limiting groove 11 on both sides, and the limiting groove 11 is slidably connected to the limiting plate 9; a rotating rod 12 is rotatably connected inside the support plate 4, and both ends of the rotating rod 12 extend to the outside of the box body 1; gears 13 are fixedly connected to both ends of the rotating rod 12; toothed plates 14 are meshed on both sides of the gears 13, and the toothed plates 14 are slidably connected to the box body 1; two pairs of toothed plates 14 are fixedly connected to two sealing plates 6 respectively; an activated carbon adsorption component is installed at the end of the exhaust pipe 3 away from the box body 1; the activated carbon adsorption component is used to further adsorb the gas filtered by the filter box 10.During operation, when acidic or alkaline mist gas is drawn into the chamber 1 through the inlet pipe 2, the gas containing mist particles passes through the filter boxes 10 on the top and bottom surfaces of the support plate 4, where most of the mist particles are filtered out. The filtered gas then passes through the activated carbon adsorption assembly, where the activated carbon further adsorbs harmful impurities, facilitating further waste gas treatment. However, after prolonged exposure to mist-containing gas, excessive mist particles accumulate inside the filter box 10, affecting its filtration efficiency. In this case, the filter box 10 needs to be replaced. The user rotates the rotating rod 12, which drives the gear 13 to rotate. This causes the two meshing toothed plates 14 to slide along the chamber 1, pushing the two sealing plates 6 away from the chamber 1. As the sealing plates 6 move away from the chamber 1, they cause the partition plate 8 to move from the through-hole... The user moves the housing 1 out of slot 5, and then pushes the filter box 10 from one side. The filter box 10 slides out between the paired partitions 8 along the limiting plate 9, allowing the user to remove the used filter box 10. The user then aligns the limiting slot 11 of the new filter box 10 with the limiting plate 9 on the surface of the partition 8 and inserts it between the paired partitions 8, thus completing the replacement of the new filter box 10. The user then rotates the rotating rod 12, causing the sealing plate 6 to snap back onto the surface of the housing 1. At this time, the filter box 10 between the partitions 8 is also inserted into the housing 1, and the sealing ring 7 on the surface of the sealing plate 6 presses tightly against the surface of the housing 1, sealing the through slot 5. Through the cooperation of the rotating rod 12, gear 13, and toothed plate 14, the user can quickly and in batches remove and replace the filter boxes 10, thereby reducing the difficulty of replacement and improving maintenance efficiency.

[0023] like Figure 1 , Figure 3 and Figure 5As shown, connecting posts 15 are fixedly connected to both sides of the housing 1 at positions corresponding to the rotating rod 12, and the rotating rod 12 is rotatably connected to the connecting posts 15; a sleeve 16 is threadedly connected to the surface of the connecting post 15; a crown gear 17 is rotatably connected to the side of the sleeve 16 away from the housing 1; a spring 18 is rotatably connected between the sleeve 16 and the housing 1; a crown gear 19 is fixedly connected to the side of the gear 13 near the crown gear 17, and the crown gear 19 meshes with the crown gear 17; a limiting rod 20 is fixedly connected to the inner side of the crown gear 17, and the limiting rod 20 is slidably connected to the connecting post 15; during operation, when the user needs to rotate the rotating rod 12, the user needs to screw the sleeve 16 onto the surface of the connecting post 15, thereby... This will cause the crown gear 17 and the limiting rod 20 to move away from the crown gear 19. At this time, the crown gear 17 and the crown gear 19 will disengage, so the user can rotate the rotating rod 12 normally. When the user needs to lock the rotating rod 12, the user needs to screw the sleeve 16 so that the sleeve 16 and the connecting column 15 are disengaged. At this time, the compressed spring will push the sleeve 16, the limiting rod 20 and the crown gear 17 towards the crown gear 19, and make the crown gear 17 and the crown gear 19 mesh, thereby locking the crown gear 19 and restricting the rotation of the rotating rod 12. This makes it convenient for the user to fix the position of the sealing plate 6, and makes it convenient for the user to remove or install the filter box 10 between the partitions 8.

[0024] like Figures 1 to 3 As shown, a pair of pressure plates 21 are provided on the sides of the two sealing plates 6 that are far apart from each other; a connecting block 22 is fixedly connected to the side of the housing 1 near the exhaust pipe 3 at the corresponding position of the pressure plate 21, and the pressure plate 21 and the connecting block 22 are slidably connected; during operation, after the sealing plate 6 is fastened to the surface of the housing 1, the pressure plate 21 needs to be slid so that it slides along the connecting block 22 and presses against the surface of the sealing plate 6, thereby pressing the sealing plate 6 tightly against the surface of the housing 1, thereby improving the sealing performance between the sealing plate 6 and the housing 1, and preventing fog from overflowing from the through groove 5, thereby causing pollution to the surrounding environment.

[0025] like Figure 1 and Figure 3As shown, a connecting plate 23 is fixedly connected between the pairs of pressure plates 21; a drive rod 24 is threadedly connected to the side of each connecting plate 23 near the exhaust pipe 3; the two drive rods 24 are connected to the output shaft of the drive motor through a gear set; during operation, when the user needs to slide the pressure plate 21, the user can drive the two drive rods 24 to rotate through the drive motor, and the rotating drive rods 24 will drive the two connecting plates 23 to move, thereby realizing the synchronous movement of the four pressure plates 21. At the same time, after the sealing plate 6 drives the filter box 10 away from the housing 1, the user can also control the movement of the connecting plate 23 and the pressure plate 21 to push the filter box 10 between the partitions 8, thereby realizing the synchronous top movement of multiple filter boxes 10, thus making it convenient for the user to remove the filter box 10 in one step and reducing the user's maintenance difficulty.

[0026] like Figure 2 , Figure 3 and Figure 6 As shown, two pairs of limiting blocks 25 are fixedly connected to the top and bottom surfaces of the housing 1, near the end of the air intake pipe 2; limiting holes 26 are formed on the surface of the limiting blocks 25, and the limiting holes 26 are adapted to the pressure plate 21; a rotating groove 27 is formed at the end of the pressure plate 21 near the air intake pipe 2; a push plate 28 is rotatably connected in the rotating groove 27; during operation, when the user needs to push the filter box 10 through the pressure plate 21, the user rotates the push plate 28 to rotate it to a vertical position, so that the push plate 28 can contact the surface of the filter box 10, thereby increasing the contact area between the pressure plate 21 and the filter box 10, thus preventing the filter box 10 from being damaged due to pressure. The pressure plate 21 softens due to prolonged contact with the mist, and its small contact area can cause it to insert into the filter box 10, resulting in damage to the filter box 10 and leakage of mist particles. When the sealing plate 6 is fastened to the surface of the housing 1, the user needs to rotate the push plate 28 to make it horizontal while controlling the pressure plate 21 to press against the surface of the sealing plate 6. At this time, the push plate 28 and the pressure plate 21 can pass through the limiting hole 26 on the surface of the limiting block 25, thereby providing downward pressure to the end of the pressure plate 21 away from the connecting block 22, so that the sealing plate 6 is subjected to more even force, thereby further improving the sealing performance between the sealing plate 6 and the housing 1.

[0027] like Figure 4 and Figure 7 As shown, a pair of guide plates 29 are installed on the top surface of the support plate 4 near the side of the partition 8 close to the air inlet pipe 2; the cross-section of the two guide plates 29 forms a V structure; during operation, when the partition 8 is inserted into the box 1, the two guide plates 29 will be located on the windward side of the partition 8. At this time, the mist drawn into the box 1 will enter the filter box under the guidance of the guide plates 29, thereby improving the filtration effect of the mist.

[0028] like Figure 7As shown, a sliding plate 30 is slidably connected to the top surface of the support plate 4 at the corresponding position of the partition 8, and the sliding plate 30 is slidably connected to the support plate 4; a spring 31 is fixedly connected between the end of the sliding plate 30 away from the guide plate 29 and the support plate 4; a magnet 32 ​​is fixedly connected to the side of the pair of guide plates 29 near the partition 8, and the magnet 32 ​​is located at the bottom of the guide plate 29; the partition 8 is made of magnetizable metal; during operation, when the partition 8 is inserted into the position of the magnet 32, the magnet 32 ​​will be attracted to the partition 8, thereby fastening the guide plate 29 onto the partition 8, and at the same time driving the sliding plate 30 to compress the spring 31. When the user needs to pull out the partition 8, after the partition 8 is separated from the magnet 32, the compressed spring 31 will recover, thereby driving the sliding plate 30 and the guide plate 29 to move away from the partition 8, thereby avoiding the guide plate 29 and the magnet 32 ​​from affecting the movement of the partition 8.

[0029] like Figure 1 , Figure 8 , Figure 9 and Figure 10 As shown, the activated carbon adsorption assembly includes a receiving tube 33, which is installed at the end of the exhaust pipe 3 away from the housing 1. A baffle 34 is fixedly connected to the end of the receiving tube 33 near the exhaust pipe 3. A through hole 35 is opened on the surface of the baffle 34. A sliding rod 36 is slidably connected in the through hole 35. Multiple evenly arranged activated carbon cakes 37 are inserted into the surface of the sliding rod 36. A stop plate 38 is fixedly connected to the end of the sliding rod 36 away from the baffle 34. During operation, when dealing with users of different flow rates of mist, users can insert activated carbon cakes 37 of different thicknesses and quantities into the surface of the sliding rod 36 according to their own needs. Then, the sliding rod 36 is inserted into the through hole 35 on the surface of the baffle 34, thereby clamping the activated carbon cakes 37 between the baffle 34 and the stop plate 38. By using users to select activated carbon cakes 37 of different thicknesses and quantities according to their own needs, the cost of activated carbon cakes 37 can be reduced while ensuring purification and adsorption efficiency.

[0030] like Figures 9 to 10 As shown, the receiving tube 33 and the exhaust pipe 3 are fixedly connected by bolts; a support frame 39 is fixedly connected to the bottom of the receiving tube 33; rollers 40 are evenly arranged and rotatably connected to the bottom of the support frame 39; a nut 41 is threadedly connected to the side of the slide rod 36 away from the abutment plate 38; when the user needs to replace the activated carbon cake 37 during operation, the user needs to first contact the bolt connection between the receiving tube 33 and the exhaust pipe 3, and then push the support frame 39 so that it is against the rollers 40 at the bottom, moving the receiving tube 33 away from the exhaust pipe 3. In this way, the user has enough space to replace the activated carbon cake 37 in the receiving tube 33. At the same time, the nut 41 at the end of the slide rod 36 can help the user to lock the activated carbon cake 37, so that the activated carbon cake 37 is tightly clamped between the abutment plate 38 and the baffle plate 34.

[0031] like Figures 9 to 11 As shown, a pair of symmetrically arranged rotating plates 42 are rotatably connected to the end of the slide rod 36 away from the abutment plate 38; a clearance groove 43 is provided on the surface of the baffle plate 34; the clearance groove 43 communicates with the through hole 35 and passes through the baffle plate 34; during operation, when the user needs to remove the activated carbon cake 37 from the receiving tube 33, the user needs to first unscrew the nut 41 from the surface of the slide rod 36, and then rotate the two rotating plates 42 so that they are aligned with the clearance groove 43. Then the user pulls the abutment plate 38, which drives the slide rod 36 and the rotating plates 42 to move towards the outside of the receiving tube 33. During this process, the rotating plates 42 can pass through the clearance groove 43 and squeeze the activated carbon cake 37, thereby pushing the activated carbon cake 37 out of the receiving tube 33, which makes it convenient for the user to remove the activated carbon cake 37 and reduces the difficulty for the user to replace the activated carbon cake 37.

[0032] During operation, when acidic or alkaline mist gas is drawn into the chamber 1 through the inlet pipe 2, the gas containing mist particles passes through the filter boxes 10 on the top and bottom surfaces of the support plate 4, where most of the mist particles are filtered out. The filtered gas then passes through the activated carbon adsorption assembly, where the activated carbon further adsorbs harmful impurities, facilitating further waste gas treatment. However, after prolonged exposure to mist-containing gas, excessive mist particles accumulate inside the filter box 10, affecting its filtration efficiency. In this case, the filter box 10 needs to be replaced. The user rotates the rotating rod 12, which drives the gear 13 to rotate. This causes the two meshing toothed plates 14 to slide along the chamber 1, pushing the two sealing plates 6 away from the chamber 1. As the sealing plates 6 move away from the chamber 1, they cause the partition plate 8 to move from the through-hole... The user moves the housing 1 out of slot 5, and then pushes the filter box 10 from one side. The filter box 10 will slide out between the paired partitions 8 along the limiting plate 9, allowing the user to remove the used filter box 10. Then, the user aligns the limiting slot 11 of the new filter box 10 with the limiting plate 9 on the surface of the partition 8 and inserts it between the paired partitions 8, thus completing the replacement of the new filter box 10. The user then rotates the rotating rod 12 again, which drives the sealing plate 6 to snap back onto the surface of the housing 1. At this time, the filter box 10 between the partitions 8 will also be inserted into the housing 1. At the same time, the sealing ring 7 on the surface of the sealing plate 6 is also pressed tightly against the surface of the housing 1, achieving a seal on the through slot 5. Thus, through the cooperation of the rotating rod 12, gear 13 and toothed plate 14, the user can quickly and in batches remove and replace the filter boxes 10, thereby reducing the user's replacement difficulty and improving maintenance efficiency.

[0033] When the user needs to rotate the rotating rod 12, the user needs to screw the sleeve 16 onto the surface of the connecting post 15. This will cause the crown gear 17 and the limiting rod 20 to move away from the crown gear 19. At this time, the crown gear 17 and the crown gear 19 will disengage, so the user can rotate the rotating rod 12 normally. When the user needs to lock the rotating rod 12, the user needs to screw the sleeve 16 so that the sleeve 16 and the connecting post 15 are disengaged. At this time, the compressed spring will push the sleeve 16, the limiting rod 20 and the crown gear 17 against the crown gear 19, and make the crown gear 17 and the crown gear 19 mesh, thereby locking the crown gear 19 and restricting the rotation of the rotating rod 12. This makes it convenient for the user to fix the position of the sealing plate 6, and makes it convenient for the user to remove or install the filter box 10 between the partitions 8.

[0034] After the sealing plate 6 is fastened to the surface of the box 1, the sliding pressure plate 21 needs to be slid along the connecting block 22 and pressed against the surface of the sealing plate 6, thereby pressing the sealing plate 6 tightly against the surface of the box 1, thereby improving the sealing performance between the sealing plate 6 and the box 1, and preventing fog from overflowing from the through groove 5, thus causing pollution to the surrounding environment.

[0035] When the user needs to slide the pressure plate 21, the user can drive the two drive rods 24 to rotate via the drive motor. The rotating drive rods 24 will then drive the two connecting plates 23 to move, thereby achieving synchronous movement of the four pressure plates 21. At the same time, after the sealing plate 6 drives the filter box 10 away from the housing 1, the user can also control the movement of the connecting plate 23 and the pressure plate 21 to push the filter box 10 between the partitions 8, thereby achieving synchronous top movement of multiple filter boxes 10. This makes it convenient for the user to remove the filter box 10 in one step, reducing the user's maintenance difficulty.

[0036] When the user needs to push the filter box 10 through the pressure plate 21, the user rotates the push plate 28 to a vertical position, so that the push plate 28 can contact the surface of the filter box 10. This increases the contact area between the pressure plate 21 and the filter box 10, thus preventing the filter box 10 from softening due to long-term contact with mist. If the contact area of ​​the pressure plate 21 is too small, it will cause the pressure plate 21 to insert into the filter box 10, causing damage to the filter box 10 and resulting in leakage of mist particles. When the sealing plate 6 is fastened to the surface of the housing 1, the user needs to rotate the push plate 28 to a horizontal position while controlling the pressure plate 21 to press against the surface of the sealing plate 6. At this time, the push plate 28 and the pressure plate 21 can pass through the limiting hole 26 on the surface of the limiting block 25, thereby providing downward pressure to the end of the pressure plate 21 away from the connecting block 22, so that the force on the sealing plate 6 is more even, thereby further improving the sealing performance between the sealing plate 6 and the housing 1.

[0037] When the partition 8 is inserted into the housing 1, the two guide plates 29 will be positioned on the windward side of the partition 8. At this time, the mist drawn into the housing 1 will enter the filter box under the guidance of the guide plates 29, thereby improving the filtration effect of the mist.

[0038] When the partition 8 is inserted into the position of the magnet 32, the magnet 32 ​​will be attracted to the partition 8, thereby securing the guide plate 29 onto the partition 8. At the same time, the slide plate 30 will compress the second spring 31. When the user needs to remove the partition 8, after the partition 8 is separated from the magnet 32, the compressed spring 31 will recover, thereby causing the slide plate 30 and the guide plate 29 to move away from the partition 8, thus preventing the guide plate 29 and the magnet 32 ​​from affecting the movement of the partition 8.

[0039] When dealing with mist processing users with different flow rates, users can insert activated carbon cakes 37 of varying thicknesses and quantities into the surface of the slide bar 36 according to their own needs. Then, the slide bar 36 is inserted into the through hole 35 on the surface of the baffle 34, thereby clamping the activated carbon cakes 37 between the baffle 34 and the abutment 38. By selecting activated carbon cakes 37 of different thicknesses and quantities according to their own needs, users can reduce the cost of activated carbon cakes 37 while ensuring purification and adsorption efficiency.

[0040] When the user needs to replace the activated carbon cake 37, the user needs to first contact the bolt connection between the receiving tube 33 and the exhaust pipe 3, and then push the support frame 39 so that it is against the bottom roller 40, moving the receiving tube 33 away from the exhaust pipe 3. In this way, the user has enough space to replace the activated carbon cake 37 in the receiving tube 33. At the same time, the nut 41 at the end of the slide rod 36 can help the user to lock the activated carbon cake 37, so that the activated carbon cake 37 is tightly clamped between the back plate 38 and the baffle 34.

[0041] When the user needs to remove the activated carbon cake 37 from the receiving tube 33, the user first needs to unscrew the nut 41 from the surface of the slide bar 36, and then rotate the two rotating plates 42 so that they are aligned with the relief groove 43. Then the user pulls the abutment plate 38, which drives the slide bar 36 and the rotating plate 42 to move out of the receiving tube 33. During this process, the rotating plate 42 can pass through the relief groove 43 and squeeze the activated carbon cake 37, thereby pushing the activated carbon cake 37 out of the receiving tube 33. This makes it convenient for the user to remove the activated carbon cake 37 and reduces the difficulty of the user replacing the activated carbon cake 37.
