[0034] Working process: When the device is in use, the external power supply is energized. When filtering dust, dust is transported to the inside of the outer shell 21 through the air inlet pipe 3. A valve is installed at the lower end of the collecting box 1. At this time, the valve at the lower end of the collecting box 1 is closed, and the dust passes through the dust bag 8. The dust bag 8 filters the dust, and the dust particles remain on the outside of the dust bag 8. The filtered gas enters the upper part of the upper mounting plate 26 from the inside of the dust bag 8 and flows out through the air outlet pipe 4. The bottom end of the dust bag 8 is fixed to the top of the fixing seat 24, and the upper end of the dust bag 8 is fixed to the inner side of the upper mounting plate 26. When the particles on the outside of the dust bag 8 are cleaned, the servo is started. The motor 5 and the servo motor 5 drive the winding wheel 6 to rotate, and the winding wheel 6 winds the steel wire 7. The steel wire 7 moves inside the upper end of the outer shell 21 and inside the upper mounting plate 26. The outer side of the steel wire 7 fits with the sealing ring provided on the inner side of the upper mounting plate 26, which can prevent the dust from overflowing from the lower end of the upper mounting plate 26 and the lower part of the air outlet pipe 4. The steel wire 7 pulls the second copper tube 94 to move upward, and the second copper tube 94 drives the outer sleeve 92 to move. The outer sleeve 92 drives multiple outer sleeves 92 and the second copper tube 94 to move upward at the same time through the first through tube 93. The rectangular slide 91 is slidably connected to the inner side of the limiting slide 22, which plays a role in the movement of multiple outer sleeves 92. The outer ring 92 has the function of limiting the position. When the outer ring 92 moves, the magnetic inner ring 96 is driven to move upward under the effect of magnetic attraction. With the cooperation of the magnetic inner ring 96, the inner side of the outer ring 92 can be in close contact with the outer side of the dust bag 8, and the outer side of the magnetic inner ring 96 can be in close contact with the inner side of the dust bag 8. When the outer ring 92 and the magnetic inner ring 96 move, the first steel ball 98 and the second steel ball 99 can scrape and crush the dust solidified on the dust bag 8, thereby improving the cleaning effect of the dust bag 8. At the same time, the filter suction fan 25 is started, and the filter suction fan 25 exhausts air from the inside of the hose 27. The outer ring 92 is close to the dust bag 8. A number of through holes are opened inside, and the through holes on the outer ring 92 fit with the dust bag 8 to prevent a large amount of dust from being sent into the through holes of the outer ring 92. The crushed particles on the dust bag 8 enter the annular air duct 95 from the through holes, enter the first through pipe 93 and the second copper pipe 94 through the connecting port 97, and enter the hose 27 again to be discharged through the filter suction fan 25. The rear end of the filter suction fan 25 is equipped with a filter block and a collection box, so that the dust bag 8 can be cleaned while the dust removal device is working, without stopping the dust removal device, thereby improving the filtering efficiency of the dust bag 8 and not affecting the continuous production of the enterprise.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
