Description

Technical Field

[0001] This utility model relates to the field of waste paint mist treatment technology, specifically a waste paint mist collection and purification device for a color-coated aluminum coil production line. Background Technology

[0002] The production of color-coated aluminum coils requires coating the surface of the aluminum coils using spraying or roller coating processes, followed by high-temperature curing to form a protective and decorative layer. During this process, the organic solvents in the coating will evaporate, and some of the coating will atomize to form waste paint mist. The paint mist not only contains solid particles such as pigments and resins, but also volatile organic compounds such as xylene and formaldehyde. If this waste paint mist is directly diffused, it will adhere to the production equipment and the ground, corroding the equipment and increasing cleaning and maintenance costs. Subsequent volatilization will also continue to pollute the air in the workshop. On the other hand, long-term inhalation by workers can cause respiratory diseases, and skin contact can lead to dry skin, inflammation, and other problems. Long-term exposure to benzene-based substances may even induce serious diseases such as leukemia.

[0003] Existing waste paint mist purification devices typically use a fan to collect the waste paint mist, which is then filtered by a filter. While this method can clean up the waste paint mist, some of the waste paint mist may not be absorbed into the purification device due to the fixed inlet, which can still pose a hazard to workers and equipment.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example: Figures 1-5 As shown, the present invention provides a waste paint mist collection and purification device for a color-coated aluminum coil production line, including a housing 1, and an angle adjustment mechanism 2 is provided on the left side of the inner and outer sides of the housing 1. The angle adjustment mechanism 2 includes a telescopic hose 4, which can extend or shorten to facilitate adjustment of the position of the suction nozzle 5. The suction nozzle 5 is fixedly connected to the left end of the telescopic hose 4, and a connecting ring 6 is fixedly connected to the bottom of the suction nozzle 5. The connecting ring 6 connects and fixes the suction nozzle 5 to the connecting rod 7. The connecting rod 7 is fixedly connected to the middle of the outer bottom wall of the connecting ring 6. The bottom end of the connecting rod 7 is rotatably connected to the inner side of the U-shaped plate 8 through a pivot 24. When the connecting rod 7 rotates inside the U-shaped plate 8, it can cause the top suction nozzle 5 to rotate up and down. The U-shaped plate 8 is fixedly connected to the middle left side of the top wall of the mounting plate 13. On the side, gears 9 are fixedly connected to both ends of the rotating shaft 24. Gear plates 10 are meshed with the bottom of each gear 9. When the gear plates 10 move left and right, they can drive the gears 9 to rotate, thereby causing the rotating shaft 24 fixed to the gears 9 to rotate. The rotation of the rotating shaft 24 causes the top connecting rod 7 to rotate. A connecting plate 11 is fixedly connected to the right end between the two sets of gear plates 10. An electric telescopic rod 12 is fixedly connected to the right side of the middle part of the top wall of the mounting plate 13. The electric telescopic rod 12 is the power component for the left and right movement of the gear plates 10. When the electric telescopic rod 12 is working, the extension and retraction of the output end can cause the connecting plate 11 and the gear plates 10 to move left and right.

[0017] The output end of the electric telescopic rod 12 is fixedly connected to the connecting plate 11. The bottom wall of the mounting plate 13 is fixedly connected to the output end of the drive motor 14. The drive motor 14 is fixedly connected to the left end of the fixing plate 15. The fixing plate 15 is fixedly connected to the lower middle part of the left side wall of the housing 1. During the operation of the drive motor 14, the output shaft rotates, causing the mounting plate 13 and its top components to rotate, thereby causing the air extraction nozzle 5 to swing left and right.

[0018] The flexible hose 4 passes through and is fixedly connected to the middle of the connecting shell 3. The connecting shell 3 passes through and is fixedly connected to the middle of the left side wall of the shell 1. The filter cotton 21 is fixedly connected to the left end of the inner side of the shell 1. The filter cylinder 18 is fixedly connected to the middle of the inner side of the shell 1. The filter bag 19 is provided on the side wall of the filter cylinder 18 to increase the contact area with air, thereby improving the filtration efficiency.

[0019] An air inlet 20 is provided at the middle of the left end of the filter cylinder 18. A filter bag 19 is provided on the inner wall of the filter cylinder 18. A filter plate 22 is fixedly connected to the right end of the filter cylinder 18 inside the housing 1. An exhaust fan 23 is provided on the right side of the filter plate 22 inside the housing 1. An exhaust window 17 is provided at the bottom of the middle of the right side wall of the housing 1. Universal wheels 16 are provided at the four corners of the bottom of the housing 1. The universal wheels 16 can reduce the difficulty of moving the purification device.

[0020] Working principle: When collecting and purifying waste paint mist, the drive motor 14 and the electric telescopic rod 12 are started. The output shaft of the drive motor 14 rotates, causing the mounting plate 13 to rotate, which in turn causes the suction nozzle 5 on the top of the mounting plate 13 to rotate back and forth. The output end of the electric telescopic rod 12 extends and retracts, causing the connecting plate 11 and the toothed plate 10 to move left and right. During the movement of the toothed plate 10, the gear 9 rotates, which causes the connecting rod 7 and the suction nozzle 5 to rotate up and down. Adjusting the suction position of the suction nozzle 5 improves the accuracy of waste paint mist collection. After aligning with the waste paint mist, the exhaust fan 23 is started. The exhaust fan 23 generates suction, which causes the waste paint mist to enter the housing 1 from the connecting shell 3. After passing through the filter cotton 21, the filter bag 19 and the filter plate 22 for triple filtration, the treated gas is discharged from the exhaust window 17, completing the waste paint mist collection and purification operation.
