The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] Embodiment 1:

[0035] When it is necessary to remove the smoke, the smoke is introduced into the dust removal tube 1, and the dust in the smoke is filtered and retained by the dust filter installed inside the dust removal tube 1. The filtered smoke is guided out through the dust filter to achieve dust removal. When it is necessary to clean the dust attached to the dust filter, during the dust removal process, the airbag scraper and the airbag moving part are inflated at the same time, so that the two are tightly fitted with the inner wall of the dust removal tube 1 after expansion, and the friction force is used to make the two hover on the dust removal tube. Inside the cylinder 1, when cleaning the dust in the dust filter, the airbag scraper is deflated so that the airbag scraper is no longer in contact with the inner wall of the dust filter cylinder 1, while the airbag moving part remains inflated. At this time, when the waterproof motor 24 drives the threaded rod 23 to rotate, the moving frame 22 moves downward under the guidance of the limit cylinder 16. The moving frame 22 drives the airbag scraper to move during the downward movement, and the airbag scraper scrapes the dust attached to the dust filter during the movement.

[0036] When the movable frame 22 moves the limit distance relative to the limit cylinder 16, the airbag scraper is inflated again and the airbag movable member is deflated. At this time, when the waterproof motor 24 drives the threaded rod 23 to rotate in the opposite direction, the airbag movable member moves downward relative to the airbag scraper, so that the airbag scraper and the airbag movable member are driven by the telescopic mechanism to move in a creeping manner along the inner wall of the dust removal cylinder 1 until the airbag scraper completely scrapes off the dust on the dust filter.

[0037] The dust filter part includes a mounting seat 17, a filter screen 18 and a mounting seat 2 19, the two ends of the filter screen 18 are respectively welded to the bottom of the mounting seat 2 19 and the top of the mounting seat 17, and a connecting pipe 7 is welded to the top of the mounting seat 2 19, and the connecting pipe 7 and the top of the dust removal cylinder 1 are welded and fixed;

[0038] The filter screen 18 can be provided to filter and retain dust in the smoke, and the filtered and retained smoke is finally discharged through the connecting pipe 7.

[0039] Further, the airbag scraper comprises a slide plate 20 and an airbag body 21, the slide plate 20 is slidably connected to the outer wall of the guide rod 14, and the airbag body 21 is bonded to the outer wall of the slide plate 20, the airbag moving member comprises an airbag body 18 and a slide plate 15, the slide plate 15 is slidably connected to the outer wall of the guide rod 14, and the airbag body 18 is bonded to the outer wall of the slide plate 15;

[0040] The moving paths of the slide plates 20 and 15 can be guided by the guide rod 14. The airbag body 1 8 and the airbag body 21 expand and fit with the circumferential inner wall of the dust removal cylinder 1 after inflation. The dust on the dust filter part can be scraped off by providing the slide plate 20.

[0041] Furthermore, a mounting plate 11 is welded to the outer wall of the dust removal cylinder 1, and an air pump 5 is fixed to the outer wall of one side of the mounting plate 11 by bolts, and a hose 10 is fixed to the output end of the air pump 5 by bolts, and an intermediate tube 26 is integrally formed on the outer wall of the hose 10, and the two ends of the intermediate tube 26 and the airbag body 21 and the airbag body 1 8 are connected respectively by a solenoid valve 27 and a solenoid valve 1 25;

[0042] By providing an air pump 5, air can be inflated into the hose 10 and the intermediate tube 26. By controlling the switching of the solenoid valve 1 25 and the solenoid valve 2 27, the airbag body 2 21 or the airbag body 8 can be inflated, thereby realizing the alternating creeping between the airbag scraper and the airbag moving part.

[0043] Furthermore, a support plate 3 is fixed to the top of the dust removal cylinder 1 by bolts, and a negative pressure fan 2 is fixed to the outer wall of one side of the support plate 3 by bolts, and the outer wall of one side of the negative pressure fan 2 and one end of the connecting pipe 7 are fixedly connected, and a dust suction pipe 6 is welded to the side wall of the dust removal cylinder 1;

[0044] The negative pressure fan 2 can be provided to induce air, so that smoke and dust are introduced into the dust removal cylinder 1 through the dust suction pipe 6 under the action of negative pressure, and the smoke and dust are removed by the dust filter.

[0045] Furthermore, a support frame 4 is fixed to the outer circumferential wall of the dust removal cylinder 1 by bolts;

[0046] The entire device can be supported by providing a support frame 4 .

[0047] When the present embodiment is in use, the negative pressure fan 2 is first started, and the smoke is introduced into the dust collection tube 1 through the negative pressure fan 2 through the dust suction pipe 6, and the dust in the smoke is filtered and retained by the dust filter. When it is necessary to clean the dust attached to the dust filter, during the dust removal process, the airbag scraper and the airbag moving part are inflated at the same time, so that the two are tightly fitted with the inner wall of the circumference of the dust collection tube 1 after expansion, and the friction force is used to make the two hover inside the dust collection tube 1. When cleaning the dust attached to the dust filter, the airbag scraper is deflated so that the airbag scraper is no longer in contact with the inner wall of the dust collector 1, while the airbag movable member remains inflated. At this time, when the waterproof motor 24 drives the threaded rod 23 to rotate, the movable frame 22 moves downward under the guidance of the limit cylinder 16. The movable frame 22 drives the airbag scraper to move during the downward movement, and the airbag scraper scrapes off the dust attached to the dust filter during the movement.

[0048] Embodiment 2:

[0049] A dust removal device for powder coating production, such as Figures 1 to 7As shown, in order to facilitate the cleaning of the scraped dust; this embodiment makes the following supplements on the basis of embodiment 1: the through hole opened at the bottom of the dust removal cylinder 1 is embedded with a liquid inlet pipe 13, and a valve 9 is fixed to one end of the liquid inlet pipe 13 by bolts, and the other end of the liquid inlet pipe 13 is connected to a nozzle 34 through a rotating joint, and a nozzle 32 is welded on the top of the nozzle 34, and a nozzle head 33 is welded on the circumferential outer wall of the nozzle 32;

[0050] When the airbag moving part is deflated, the dust scraped by the airbag scraping part will fall onto the slide plate 15. When the slide plate 15 moves to the same height as the nozzle 33, flushing liquid is injected into the liquid inlet pipe 13 and the nozzle 34, so that the nozzle 33 sprays the flushing liquid to flush the dust on the slide plate 15. The flushed dust finally moves to the bottom of the dust collector 1 through the gap between the airbag body 8 and the dust collector 1.

[0051] The outer wall of the nozzle 34 is fixed with a rotating column 29, and the outer wall of the rotating column 29 is provided with an arc groove 28. The bottom of the slide plate 15 is fixed with a vertical plate 31 by bolts, and the outer wall of one side of the vertical plate 31 is fixed with a toggle head 30 used in conjunction with the arc groove 28 by screws.

[0052] When the slide plate 15 moves in the vertical direction, the driving action of the toggle head 30 on the arc groove 28 causes the rotating column 29 to drive the nozzle 33 on the nozzle 32 to rotate synchronously during the rotation process. During the rotation process, the nozzle 33 allows the flushing liquid to flush the dust more evenly, thereby reducing the flushing blind angle.

[0053] A valve 2 12 is fixed to the bottom of the dust removal cylinder 1 by bolts;

[0054] The waste liquid after flushing can be discharged by providing a valve 12.
