Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and particularly relates to an air purification device for a roll-coated color aluminum plate production line. Background Art

[0002] During the production process of roll-coated color aluminum plates, various chemical substances such as coatings, solvents, and additives are used. These substances will inevitably volatilize into the air during production operations such as spraying and drying, forming polluted air containing a large amount of harmful substances and particulate matter. These pollutants will seriously affect the environmental quality of the production workshop, endanger the physical health of operators, cause health problems such as respiratory diseases and allergic reactions, and will also diffuse into the surrounding environment with the air flow, causing pollution to the atmospheric environment.

[0003] Existing air purification equipment generally filters particulate matter through filters and adsorbs VOCs through activated carbon. However, a roll-coated color aluminum plate production line usually needs to run continuously, which requires the air purification device to have stable and reliable performance and a long service life. However, during the long-term operation of existing air purification equipment, filtering components such as filter bags are easily blocked due to a large amount of dust adhesion, resulting in a decrease in filtering efficiency and an increase in air resistance. The activated carbon also needs to be replaced after use. When cleaning the filter bags and replacing the activated carbon, it is often necessary to stop the machine, which not only increases the maintenance cost and time cost of the equipment, but also reduces the production efficiency.

[0057] It further includes:

[0058] A sleeve 2, which is movably sleeved outside the central cylinder 14. A pair of baffles 21 are fixedly connected to the sleeve 2 at intervals. An annular seat 22 corresponding to the annular groove 13 is fixedly connected to the baffle 21. Partition plates 23 are fixedly connected to the circumference between the baffles 21 at equal intervals. Chambers are formed between adjacent partition plates 23. The rightmost chamber is the dust cleaning chamber, and the remaining chambers are filter chambers. Air inlet waist holes 24 are provided on the upper surface of the top plate of the bottom box 11 corresponding to the positions of the respective filter chambers. Dust outlet waist holes 25 are provided on the lower surface of the bottom plate of the bottom box 11 corresponding to the position of the dust cleaning chamber. A dust discharge pipe 26 is fixedly connected inside the right side plate of the bottom box 11. The top of the dust discharge pipe 26 is fixedly connected to the treatment cylinder 12 and covers the dust outlet waist hole 25 therein. First through slots 27 are provided on the central cylinder 14 corresponding to the positions of the respective filter chambers. The first through slots 27 are located above the fan blade group 15. Second through slots 28 are provided on the sleeve 2 corresponding to the positions of the respective chambers. The second through slots 28 are at the same height as the first through slots 27. Through holes 29 are provided in the annular seats 22 and the baffles 21 corresponding to the positions of the respective chambers;

[0059] A filtering mechanism 3, the upper and lower ends of which are slidably connected in the through holes 29;

[0060] An adsorption mechanism, which is arranged on the front and back sides of the bottom box 11 and is used for adsorbing and treating the air discharged from the bottom box 11;

[0061] A driving mechanism, which is used for driving the fan blade group 15 to rotate and for driving the sleeve 2 to rotate intermittently, and the angle of each rotation of the sleeve 2 is equal to the included angle between adjacent two chambers;

[0062] The vibration mechanism is used to drive the rightmost filtering mechanism 3 to vibrate for dust cleaning.

[0063] In this embodiment, as Figures 1 - 2 and Figures 3 - 4 shown, in the initial state, the rightmost chamber is the dust cleaning chamber, and the remaining chambers are filtering chambers.

The remaining filtering mechanisms 3 continue to perform their filtering functions. In this way, each filtering mechanism 3 can be in the position of the dust cleaning chamber in turn, so that each filtering mechanism 3 can be kept clean, maintaining a continuous and good filtering effect and avoiding equipment shutdown.

A guiding rod 565 is fixedly connected in the guiding groove 564. A guiding seat 566 is slidably connected to the guiding rod 565. A compression spring 567 is sleeved on the guiding rod 565 above the guiding seat 566. A seat body 568 is fixedly connected to the left side of the guiding seat 566. The bottom right side of the seat body 568 is inclined. An installation shaft 569 is fixedly connected to the seat body 568. Further included is a flap 5610. A jack 5611 is formed at the bottom of the flap 5610. The jack 5611 is inserted into the installation shaft 569. A torsion spring 5612 is sleeved on the installation shaft 569. Two ends of the torsion spring 5612 are respectively fixedly connected to the inner wall of the jack 5611 and the installation shaft 569. The torsion spring 5612 keeps the flap 5610 in a vertical state. A groove 5613 is formed on the upper surface of the treatment cylinder 12 corresponding to the left side of the frame 55.

[0084] Preferably, a ratchet wheel 571 is fixedly connected to the second rotating shaft 531. A pawl 572 adapted to the ratchet wheel 571 is rotatably connected to the treatment cylinder 12. A thrust spring 573 is fixedly connected between the pawl 572 and the treatment cylinder 12.

[0085] Preferably, there are four partition plates 23, and the number of teeth of the spur gear 532 is half of that of the toothed ring 533.

[0086] In this embodiment, as Figure 6 and Figure 9 shown, when the motor 52 works, it drives the output shaft 522 to rotate. The output shaft 522 drives the fourth rotating shaft 556 to rotate through the second bevel gear pair 557. As Figure 11 shown, the fourth rotating shaft 556 drives the third rotating shaft 555 to rotate through the worm gear 558 and the worm 559. As Figure 12 shown, the moving seat 56 is engaged with the reciprocating thread groove 561 on the third rotating shaft 555 through the reciprocating thread sleeve 562. When the third rotating shaft 555 rotates, it drives the moving seat 56 to move left and right reciprocally.

[0087] As Figures 9 - 15 shown, when the moving seat 56 moves to the left ( Figure 13In the state shown, the bottom of the seat body 568 contacts the upper surface of the processing cylinder 12, the flap 5610 is held in a vertical state, and the right side of the flap 5610 contacts the right side of the notch 563, so that the flap 5610 cannot rotate to the right. The flap 5610 pushes the push seat 552 to move, and the push seat 552 drives the lifting seat 544 and the pin shaft 546 to rise through the connecting rod 553. The return spring 545 is compressed, and the pin shaft 546 rises in the vertical groove 534.

[0088] When the left side of the seat body 568 is aligned with the groove 5613 ( Figure 14 In the state shown), if the moving seat 56 continues to move to the left, the seat body 568 and the flap 5610 will descend.

[0089] When the bottommost part of the flap 5610 is separated from the push seat 552 ( Figure 15 In the state shown), under the action of the return spring 545, the lifting seat 544 descends and drives the push seat 552 to move to the right through the connecting rod 553. At this time, if the moving seat 56 continues to move to the left, it will not cause the push seat 552 to move. When the lifting seat 544 descends, it drives the pin shaft 546 to move. As shown in Figure 9 Shown, due to the provision of the ratchet 571 and the pawl 572, the rotation of the rotating column 53 is limited to counterclockwise rotation only. Therefore, the pin shaft 546 descends in the spiral groove 535, thereby driving the rotating column 53 to rotate counterclockwise, as shown in Figure 4 and Figure 10 Shown, the rotating column 53 drives the second rotating shaft 531 and the spur gear 532 to rotate, and the toothed ring 533 meshing with the spur gear 532 rotates, thereby driving the sleeve 2 to rotate. The sleeve 2 drives the baffle 21, the partition plate 23 and the filtering mechanism 3 to rotate. The spiral angle of the spiral groove 535 is 180°. Therefore, after the pin shaft 546 descends in the spiral groove 535, it drives the rotating column 53 and the spur gear 532 to rotate half a turn. Since the number of teeth of the spur gear 532 is half that of the toothed ring 533, the sleeve 2 and the filtering mechanism 3 rotate 90°. Since there are four partition plates 23 and the included angle between adjacent two chambers is 90°, that is, the angle of each rotation of the filtering mechanism 3 is equal to the included angle between adjacent two chambers.

[0090] When the moving seat 56 moves to the right after reaching the leftmost side, at this time the push seat 552 has moved to the right. When the push seat 552 moves, it drives the seat body 568 to move. Since the right side of the bottom of the seat body 568 is inclined, when the right side of the bottom of the seat body 568 contacts the top of the right side wall of the groove 5613, it will cause it to rise and compress the pressure spring 567. The seat body 568 and the flap 5610 rise to the top.

[0091] When the flap 5610 contacts the push seat 552, if the moving seat 56 continues to move, the flap 5610 will rotate leftward so that the flap 5610 can pass through the push seat 552. Until the whole flap 5610 moves to the right side of the push seat 552, under the action of the torsion spring 5612, the flap 5610 returns to the vertical state again. After the moving seat 56 moves to the rightmost side and then moves leftward again, it drives the push seat 552 to move leftward, and the pin shaft 546 rises in another vertical groove 534. By circulating in this way, the intermittent 90° rotation of the filtering mechanism 3 can be realized.

[0092] Embodiment 4

[0093] The adsorption mechanism includes an adsorption box 41 and a cover plate 42; the adsorption box 41 is fixedly connected to the outer walls of the front and rear side plates of the bottom box 11. A partition net 43 is fixedly connected to the bottom of the adsorption box 41. Activated carbon 44 is contained in the adsorption box 41 above the partition net 43. Exhaust pipes 45 are longitudinally and evenly fixedly connected to the right side plate of the adsorption box 41. One end of each exhaust pipe 45 is inserted below the partition net 43. A U-shaped sealing plate 46 is fixedly connected to the upper part of the inner cavity of the adsorption box 41. The cover plate 42 is placed on the sealing plate 46. A handle 47 is fixedly connected to the cover plate 42. Flexible hoses 48 are also horizontally and evenly fixedly connected to the cover plate 42. The other ends of the flexible hoses 48 are fixedly connected to the bottom box 11. Manual valves 49 are fixedly connected to the flexible hoses 48.

[0094] In this embodiment, as Figure 1 and Figure 16 shown, the air in the bottom box 11 enters the adsorption box 41 through the flexible hose 48, and the VOCs in it are adsorbed by the activated carbon 44. The clean air is discharged from the exhaust pipe 45. When the activated carbon 44 needs to be replaced, the manual valve 49 on one side can be closed, and the cover plate 42 can be lifted through the handle 47 to replace the activated carbon 44. The adsorption mechanism on the other side continues to work, so that the air purification process continues.

[0095] The working principle of the present invention is as follows:

[0096] The driving mechanism drives the fan blade to rotate, so that the polluted air enters the filter bags 33 on the front, rear and right sides through the air inlet waist hole 24, intercepting the particulate pollutants in the air. The treated air enters the bottom box 11 and enters the adsorption box 41 through the flexible hose 48, and the VOCs are absorbed by the activated carbon 44. The clean air is discharged from the exhaust pipe 45.

[0097] And the rightmost filtering mechanism 3 is in the dust cleaning chamber, and it is driven by the vibration mechanism to vibrate up and down, so as to shake off the dust adhering to the filter bags 33. The shaken-off dust enters the dust discharge pipe 26 through the dust outlet waist hole 25 and is discharged.

[0098] During this process, the filtering mechanism 3 rotates intermittently by 90°. After one rotation, the filtering mechanisms 3 exchange positions, so as to clean each filter bag 33 in turn.

[0099] When the two adsorption mechanisms work simultaneously and the activated carbon 44 needs to be replaced, the manual valve 49 on one side can be closed first, and the activated carbon 44 on that side can be replaced while the adsorption mechanism on the other side works normally.
