Description

Technical Field

[0001] This invention relates to the field of flue gas treatment technology, specifically to a flue gas treatment mechanism for a tape coating machine. Background Technology

[0002] During the production process, especially the drying process, tape coating machines generate a large amount of high-temperature industrial waste gas containing complex volatile organic compounds (VOCs). This flue gas mainly originates from the evaporation of solvents in the coating material. Its composition is complex, its concentration fluctuates greatly, and it often carries a small amount of paint mist particles. If it is discharged directly without effective treatment, it will cause serious pollution to the atmospheric environment, endanger human health, and does not meet the increasingly stringent environmental protection regulations.

[0003] For example, the Chinese patent with announcement number CN222266634U, patent name: an activated carbon purification device for waste gas treatment, and announcement date: 2024-12-31, includes: a purification box, with an air inlet port on one side and an air outlet port on the other side, hinges on both sides of one end of the purification box, and a sealing door on the hinge, and multiple partitions inside the purification box, which divide the purification box into multiple purification chambers, each of which is equipped with a set of purification mechanisms.

[0004] The existing technologies mentioned above have the following technical problems: When existing waste gas treatment facilities adsorb harmful substances in waste gas, they usually use activated carbon for purification. However, the waste gas generated when the coating machine dries the glue on the tape will generate heat. At the same time, the adsorption and purification process of activated carbon will release heat. When the activated carbon adsorbent comes into contact with the high-temperature waste gas and the adsorption heat causes its own temperature to rise, it will aggravate the thermal movement of pollutants, making them easier to desorb from the surface of the adsorbent, thereby reducing the overall adsorption effect.

[0005] Therefore, we propose a flue gas treatment mechanism for tape coating machines to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a flue gas treatment mechanism for a tape coating machine, in order to solve the problem mentioned in the background art. Currently, existing waste gas treatment mechanisms on the market typically use activated carbon for purification when adsorbing harmful substances in waste gas. However, the waste gas generated when the coating machine dries the adhesive on the tape generates heat, and the adsorption and purification process of activated carbon also releases heat. When the activated carbon adsorbent comes into contact with the high-temperature waste gas and its own heat release causes the temperature to rise, it intensifies the thermal motion of pollutants, making them more likely to desorb from the surface of the adsorbent, thereby reducing the overall adsorption effect.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a flue gas treatment mechanism for a tape coating machine, comprising a body and a positioning seat installed at the bottom of the body, an inlet pipe and an exhaust pipe installed on the body, a water-cooled column installed inside the body, the upper middle part of the water-cooled column being fixed inside the body, a movable plate connected to the upper end of the water-cooled column, a filter plate installed on the inner side of the movable plate, an exhaust gas pipe installed in the middle of the water-cooled column, and the interior of the water-cooled column being filled with coolant, and a refrigeration unit installed in the water-cooled column. The component has a lower end of the exhaust gas pipe connected to the drainage chamber, and a first through hole is provided on the side of the drainage chamber. An adjusting sleeve is fitted on the outside of the drainage chamber, and a first notch is provided on the side of the adjusting sleeve. The adjusting sleeve is connected to the adsorption hood through the gas supply pipe. The adsorption hood is filled with activated carbon adsorption particles. A second through hole is provided on the side of the adsorption hood away from the water cooling column. A limiting sleeve fixed inside the machine body is provided on the outside of the adsorption hood. A second notch is provided on the limiting sleeve, and the second notch corresponds to the exhaust pipe.

[0008] Preferably, the movable disc can rotate at the upper end of the water-cooling column, and two filter plates are fixed inside the movable disc. A partition plate is fixed on the side of the movable disc, which divides the cavity inside the machine body into a working area and a waiting area. The air inlet pipe is located above the filter plate in the working area. The lower end of the partition plate is fixed to the adjusting sleeve, and the partition plate is also fixed to the adsorption cover. The middle part of the lower end of the partition plate is connected to the output end of the first motor.

[0009] By adopting the above technical solution, the rotation of the partition plate can drive the movable disc and the adsorption hood to rotate synchronously. By using the rotation of the adsorption hood, the filter units in the working area and the waiting area can be swapped.

[0010] Preferably, the adjusting sleeve is rotatable on the outside of the drainage cavity, and two first notches are symmetrically arranged on the adjusting sleeve, with the first notch in the working area corresponding to the first through hole on the side of the drainage cavity.

[0011] By adopting the above technical solution, and by adjusting the sleeve so that only one first notch corresponds to the first through hole on the side of the drainage cavity, the cooled exhaust gas can only enter the adsorption hood in the working area.

[0012] Preferably, a limiting post is fixed inside the adsorption cover, and a moving rod is inserted into the limiting post. The moving rod is connected to the adsorption cover by an auxiliary spring, and a magnetic block is fixed at the bottom of the moving rod. A second motor is installed inside the positioning seat and is located below the working area. A transmission rod is fixed on the output end of the second motor, and an electromagnet is embedded inside the transmission rod. A pressing block is fixed on the moving rod, and a transverse rod is provided below the pressing block. A dispersing blade is fixed on the transverse rod, and the transverse rod is connected to the limiting post by a return spring.

[0013] By adopting the above technical solution, when the moving rod rotates with the adsorption cover, the magnetic block at the lower end of the moving rod can be aligned with the electromagnet inside the transmission rod on the same vertical line.

[0014] Preferably, the moving rod forms an elastic telescopic structure through an auxiliary spring and an adsorption cover, and a first magnetic block is fixed at the end of the squeezing block on the moving rod away from the transverse moving rod. The squeezing block and the first magnetic block are combined to form an inverted frustum-shaped structure.

[0015] By adopting the above technical solution, the auxiliary spring can be used to reset and rebound the moving rod after it has moved vertically on the adsorption cover.

[0016] Preferably, the end of the transverse rod near the extrusion block is spherical, and the spherical end of the transverse rod is in contact with the side of the extrusion block in the initial state, and the transverse rod can move laterally on the adsorption cover and the limiting post.

[0017] By adopting the above technical solution, when the extrusion block moves downward, it can use the inclined side to extrude the spherical end of the transverse rod.

[0018] Preferably, a heat exchange block is provided on the side of the end of the transverse rod extending out of the adsorption hood in the working area inside the machine body, and the heat exchange block is fixed to the side of the water-cooling column. A piston plate is installed inside the heat exchange block, and the piston plate is connected to the heat exchange block by an internal spring. A guide hole is provided on the heat exchange block. A docking part is provided on the middle rod of the piston plate, and an insertion part that mates with the docking part is provided at the end of the transverse rod. A second magnetic block is fixed above the section of the transverse rod inside the limiting column.

[0019] By adopting the above technical solution, when the transverse rod moves toward the heat exchange block, the insertion part at the end of the transverse rod can be inserted into the mating part on the middle rod of the piston plate.

[0020] Preferably, the transverse rod, dispersion blade, docking part, piston plate and heat exchange block are all made of thermally conductive metal, and the piston plate is circumferentially wrapped with a sealing ring at one end inside the heat exchange block.

[0021] By adopting the above technical solution, the sealing performance of the piston plate can be improved when it moves inside the heat exchange block through the circumferential sealing ring of the piston plate.

[0022] Preferably, after the moving rod rotates synchronously with the transmission rod, the first magnetic block on the side of the pressing block on the moving rod can approach the second magnetic block on the transverse rod, and after the first magnetic block and the second magnetic block approach each other, the surfaces of the two oppositely arranged have the same magnetic polarity.

[0023] By adopting the above technical solution, the first magnetic block and the second magnetic block approach each other, thereby generating a repulsive magnetic force on the second magnetic block, causing the transverse rod to move under the action of the magnetic force.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the flue gas treatment mechanism for the tape coating machine, by passing the exhaust gas pipe through the water-cooled column, allows the exhaust gas to undergo water-cooled heat exchange during the flow process, thereby reducing the temperature of the exhaust gas entering the adsorption hood and avoiding the high temperature exhaust gas from contacting the activated carbon adsorption particles, which would accelerate the thermal movement of pollutants and reduce the adsorption and purification effect. 1. By setting the exhaust gas pipe inside the water-cooled column, the coolant inside the water-cooled column can cool down the high-temperature exhaust gas flowing in the exhaust gas pipe. At the same time, after the transverse rod and the piston plate are connected, the transverse rod can adsorb the heat inside the adsorption hood and transfer the adsorbed heat to the heat exchange block through the piston plate. Through the contact between the heat exchange block and the coolant, the inside of the adsorption hood can also be cooled down. 2. The rotation of the partition plate can drive the movable plate and the adsorption cover to rotate synchronously, thereby automatically switching the filter units in the working area and waiting area inside the machine. This avoids the machine having only a single filter unit inside, and the entire machine does not need to be shut down for maintenance and repair when the filter unit is repaired or replaced. 3. The rotation of the extrusion block and the first magnetic block enables the transverse rod to reciprocate under the action of magnetic force. The movement of the transverse rod enables the dispersion blades and the piston plate to move synchronously. The movement of the dispersion blades can agitate the activated carbon particles inside the adsorption hood, while the reciprocating movement of the piston plate can draw and discharge the coolant inside the water-cooled column, thereby improving the cooling efficiency of the refrigeration components for the coolant.

[0027] 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.

[0028] Example 1: Please refer to Figures 1-13Existing waste gas treatment mechanisms typically use activated carbon for purification when adsorbing harmful substances in waste gas. However, the waste gas generated when the coating machine dries the adhesive on the tape generates heat, and the activated carbon adsorption and purification process also releases heat. When the activated carbon adsorbent comes into contact with the high-temperature waste gas and its own heat release causes the temperature to rise, it intensifies the thermal motion of pollutants, making them more likely to desorb from the adsorbent surface, thereby reducing the overall adsorption effect. To solve this technical problem, this embodiment discloses the following technical content: a flue gas treatment mechanism for a tape coating machine, including a body 1 and a positioning seat 2 installed at the bottom of the body 1. An air inlet pipe 3 and an exhaust pipe 18 are installed on the body 1. A water-cooled column 4 is installed inside the body 1, and the water-cooled column 4... The upper middle part is fixed inside the body 1. The upper end of the water-cooled column 4 is connected to a movable plate 5, and a filter plate 6 is installed on the inner side of the movable plate 5. An exhaust gas pipe 8 is installed in the middle of the water-cooled column 4, and the interior of the water-cooled column 4 is filled with coolant. A refrigeration component is installed in the water-cooled column 4. The lower end of the exhaust gas pipe 8 is connected to the drainage cavity 9, and a first through hole 10 is opened on the side of the drainage cavity 9. An adjusting sleeve 11 is fitted on the outside of the drainage cavity 9, and a first notch 12 is opened on the side of the adjusting sleeve 11. The adjusting sleeve 11 is connected to the adsorption hood 14 through a gas supply pipe 13. The interior of the adsorption hood 14 is filled with activated carbon adsorption particles. A second through hole 15 is opened on the side of the adsorption hood 14 away from the water-cooled column 4, and a fixed part is provided on the outside of the adsorption hood 14 inside the body 1. The limiting sleeve 16 of the part has a second notch 17, which corresponds to the exhaust pipe 18. The adsorption cover 14 has a limiting post 20 fixed inside, and a moving rod 21 is inserted into the limiting post 20. The moving rod 21 is connected to the adsorption cover 14 through an auxiliary spring 22, and a magnetic block 23 is fixed at the bottom of the moving rod 21. The positioning seat 2 has a second motor 24 installed inside, and the second motor 24 is located below the working area. A transmission rod 25 is fixed on the output end of the second motor 24, and an electromagnet 26 is embedded inside the transmission rod 25. A pressing block 27 is fixed on the moving rod 21, and a transverse moving rod 28 is provided below the pressing block 27. A dispersing blade 29 is fixed on the transverse moving rod 28, and the transverse moving rod 28 is connected to the return spring 3. The 0 and the limiting post 20 are interconnected. The moving rod 21 forms an elastic telescopic structure through the auxiliary spring 22 and the adsorption cover 14. The end of the squeezing block 27 on the moving rod 21 away from the transverse moving rod 28 is fixed with a first magnetic block 36. The squeezing block 27 and the first magnetic block 36 are combined to form an inverted frustum structure. The end of the transverse moving rod 28 near the squeezing block 27 is set as a ball, and the spherical end of the transverse moving rod 28 is in contact with the side of the squeezing block 27 in the initial state. The transverse moving rod 28 can move laterally on the adsorption cover 14 and the limiting post 20. A heat exchange block 31 is set on the side of the transverse moving rod 28 extending out of the adsorption cover 14 in the working area inside the machine body 1. The heat exchange block 31 is fixed to the side of the water-cooled column 4. A piston plate 32 is installed inside the heat exchange block 31.The piston plate 32 is connected to the heat exchange block 31 via a built-in spring 33. The heat exchange block 31 has a flow guide hole. A docking part 34 is provided on the middle section of the piston plate 32, and an insertion part 35, which mates with the docking part 34, is provided at the end of the transverse rod 28. A second magnetic block 37 is fixed above a section of the transverse rod 28 inside the limiting post 20. The transverse rod 28, the dispersing blade 29, the docking part 34, the piston plate 32, and the heat exchange block 31 are all made of thermally conductive metal. A sealing ring is circumferentially wrapped around one end of the piston plate 32 inside the heat exchange block 31. After the moving rod 21 rotates synchronously with the transmission rod 25, the first magnetic block 36 on the side of the pressing block 27 on the moving rod 21 can approach the second magnetic block 37 on the transverse rod 28. After the first magnetic block 36 and the second magnetic block 37 approach each other, their opposing surfaces have the same magnetic polarity.

[0029] When the fumes generated by the tape coating machine drying need to be purified, the fumes enter the machine body 1 through the inlet pipe 3. The fumes are first filtered by the filter plate 6 in the movable disc 5. The filtered fumes then enter the exhaust gas pipe 8. Since the exhaust gas pipe 8 is located inside the water-cooled column 4, the heat of the exhaust gas in the exhaust gas pipe 8 can exchange with the coolant in the water-cooled column 4, thereby achieving the purpose of cooling the exhaust gas. At the same time, a refrigeration component is installed inside the water-cooled column 4, which can continuously cool the coolant. The refrigeration component can be a semiconductor refrigeration chip or other refrigeration components. The refrigeration components are all existing technologies and will not be described in detail here. The cooled exhaust gas enters the drainage chamber 9 through the exhaust gas pipe 8. The exhaust gas in the drainage chamber 9 flows to the adsorption hood 14 through the first through hole 10 and the gas delivery pipe 13. At this time, the activated carbon adsorption particles in the adsorption hood 14 are used to further adsorb and purify the fumes. The purified exhaust gas finally passes through the side of the adsorption hood 14. The second through hole 15 and the exhaust pipe 18 discharge outwards. During the purification of exhaust gas, the electromagnet 26 in the transmission rod 25 is energized. After the electromagnet 26 is energized, it can generate a magnetic attraction force on the magnetic block 23 at the lower end of the moving rod 21, causing the moving rod 21 to move downwards. After the moving rod 21 moves, it can drive the pressing block 27 to move downwards synchronously. At this time, after the pressing block 27 moves, it can press the end of the transverse rod 28, causing the transverse rod 28 to move towards the piston plate 32. The transverse rod 28 moves in the direction of the piston plate 32. After the transverse rod 28 moves, the insertion part 35 at the end can be inserted into the docking part 34 on the middle rod body of the piston plate 32. After the transverse rod 28 and the piston plate 32 are docked, since the transverse rod 28, the dispersion blade 29, the docking part 34, the piston plate 32 and the heat exchange block 31 are all made of thermally conductive metal, the transverse rod 28 absorbs the heat inside the adsorption cover 14 and can transfer it to the heat exchange block 31 through the piston plate 32. This can also play an auxiliary role in cooling the inside of the adsorption cover 14. Simultaneously, when the magnetic block 23 at the lower end of the moving rod 21 attracts the electromagnet 26 inside the transmission rod 25, and the second motor 24 is turned on to drive the transmission rod 25 to rotate, the rotation of the transmission rod 25 can drive the moving rod 21 to rotate synchronously. After the moving rod 21 rotates, it can drive the pressing block 27 and the first magnetic block 36 to rotate synchronously. Because the pressing block 27 and the first magnetic block 36 combine to form a frustum-shaped structure, the rotation of the pressing block 27 and the first magnetic block 36 will not affect the insertion of the transverse rod 28 and the piston plate 32. When the pressing block 27 rotates with the moving rod 21, the first magnetic block 36 on the side of the pressing block 27 and the second magnetic block 37 on the transverse rod 28 approach each other, utilizing... The repulsive magnetic force between the two forces causes the transverse rod 28 to move toward the piston plate 32. When the extrusion block 27 rotates, the first magnetic block 36 and the second magnetic block 37 on the side move away from each other. The transverse rod 28 is reset and rebounded under the action of the reset spring 30, thus realizing the reciprocating movement of the transverse rod 28. The reciprocating movement of the transverse rod 28 can drive the dispersing blade 29 to move synchronously. The movement of the dispersing blade 29 inside the adsorption hood 14 can turn the activated carbon adsorption particles. The continuous turning causes the activated carbon adsorption particles to be redistributed, destroying the fixed channels and forcing the exhaust gas to contact all the activated carbon particles more evenly and fully, thereby greatly improving the overall adsorption efficiency. Secondly, since the transverse rod 28 is already engaged with the piston plate 32, the reciprocating movement of the transverse rod 28 can drive the piston plate 32 to reciprocate synchronously inside the heat exchange block 31. Through the reciprocating movement of the piston plate 32 inside the heat exchange block 31, the coolant inside the water-cooled column 4 can be drawn and discharged through the guide holes on the side of the heat exchange block 31. By drawing and discharging the coolant, the fluidity of the coolant inside the water-cooled column 4 can be effectively improved, so that the refrigeration components can cool the coolant inside the water-cooled column 4 more quickly.

[0030] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. Existing waste gas treatment mechanisms only have one set of filtration units. When the filtration unit becomes clogged or fails, it requires a long downtime for maintenance and replacement. This prolonged downtime can easily affect the overall filtration efficiency. To further solve this technical problem, the following technical content is disclosed in this example: Figures 2-5As shown, the movable disk 5 can rotate at the upper end of the water-cooling column 4, and two filter plates 6 are fixed inside the movable disk 5. A partition plate 7 is fixed on the side of the movable disk 5. The partition plate 7 divides the cavity inside the machine body 1 into a working area and a waiting area. The air inlet pipe 3 is located above the filter plate 6 in the working area. The lower end of the partition plate 7 is fixed to the adjusting sleeve 11, and the partition plate 7 is also fixed to the adsorption cover 14. The middle part of the lower end of the partition plate 7 is connected to the output end of the first motor 19. The adjusting sleeve 11 can rotate outside the drainage cavity 9, and two first notches 12 are symmetrically arranged on the adjusting sleeve 11. The first notch 12 located in the working area corresponds to the first through hole 10 on the side of the drainage cavity 9.

[0031] When the filter unit in the working area inside the machine body 1 needs maintenance or replacement, the electromagnet 26 on the transmission rod 25 is de-energized. After the electromagnet 26 is de-energized, the magnetic block 23 at the lower end of the moving rod 21 returns to its original position under the action of the auxiliary spring 22. After the moving rod 21 returns to its original position, the pressing block 27 on it releases its pressure on the transverse moving rod 28. At this time, the transverse moving rod 28 also returns to its original position under the action of the return spring 30. After the transverse moving rod 28 returns to its original position, the insertion part 35 at its end separates from the docking part 34 on the middle rod of the piston plate 32. At this time, the first motor 19 drives the partition plate 7 to rotate. After the partition plate 7 rotates, the movable disk 5 and the adsorption cover 14 can move. The synchronous rotation allows the filter units in the working area and the waiting area inside the body 1 to be swapped. After the filter units in the two areas are swapped, the entire flue gas treatment mechanism can work normally. The waiting area and the working area are isolated from each other. The filter units in the waiting area can also be replaced during operation without affecting the overall work efficiency. When the partition plate 7 rotates, the adjusting sleeve 11 can rotate synchronously. After the adjusting sleeve 11 rotates, the first notch 12 in the waiting area can rotate to correspond with the first through hole 10 on the side of the drainage cavity 9 in the working area, thus not affecting the subsequent normal airflow.
