A limit plate 21 is installed on the end of the guide rail 17 away from the mounting disk 23. A spring 22 is installed between the limit plate 21 and the mounting frame 19. A fixed plate 10 is slidably arranged in the shell 1. The fixed plate 10 is provided with a plurality of circular openings that match the position of the cloth bag 9. An inflatable airbag cover 16 is installed in the circular opening. The cloth bag 9 is located in the inflatable airbag cover 16, and the blower 12 is located above the fixed plate 10. The connection between the air inlet nozzle 3 and the shell 1 is located below the fixed plate 10.

[0031] As a technical optimization solution of the utility model, sliding blocks 14 are installed on both sides of the fixed plate 10, and a sliding groove 15 is opened on the inner wall of the shell 1. The sliding block 14 is slidably installed in the sliding groove 15. A locking bolt is inserted into the sliding block 14, and the end of the locking bolt abuts against the inner wall of the sliding groove 15. Through the coordinated use of the sliding block 14, the sliding groove 15 and the locking bolt, the height of the fixed plate 10 can be easily adjusted.

[0032] As a technical optimization scheme of the utility model, an air pump for inflating the inflatable airbag cover 16 is provided in the shell 1, and an exhaust valve for discharging the gas in the inflatable airbag cover 16 is installed on the inflatable airbag cover 16. An annular groove 24 is opened in the circular mouth, and the inflatable airbag cover 16 is installed in the annular groove 24. The air pump can facilitate inflating the inflatable airbag cover 16, and the exhaust valve can facilitate discharging the gas in the inflatable airbag cover 16. The annular groove 24 can provide a mounting portion for the inflatable airbag cover 16.

[0033] As a technical optimization solution of the utility model, a support plate 7 is installed on the inner bottom wall of the shell 1, and a bearing plate 8 is installed on the top of the support plate 7. The support plate 7 can provide a supporting portion for the bearing plate 8.

[0034] As a technical optimization solution of the utility model, the air inlet nozzle 3 is connected to a serpentine tube 11, which is connected to the shell 1. The connection between the serpentine tube 11 and the shell 1 is located below the fixed plate 10. The serpentine tube 11 can facilitate the adjustment of the position of the air inlet nozzle 3, and the position of the air inlet nozzle 3 can be adjusted as needed.

[0035] As a technical optimization solution of the utility model, the air inlet end of the blower 12 is connected to a bell mouth 13 , and the bell mouth 13 is located above the fixed plate 10 .

[0036] As a technical optimization solution of the utility model, a maintenance port is opened on the side of the shell 1, and a first sealing plate 4 is hinged on the side of the shell 1. The first sealing plate 4 closes the maintenance port. The maintenance port can facilitate the replacement of the cloth bag 9 in the shell 1 and the maintenance of the components in the shell 1.

[0037] As a technical optimization solution of the utility model, a discharge port is opened at the bottom of the shell 1, and a second sealing plate 6 is hinged at the bottom of the shell 1, and the second sealing plate 6 closes the discharge port. Two sets of universal wheels 5 are symmetrically installed at the bottom of the shell 1. The discharge port can facilitate the discharge of dust with excessive weight collected in the shell 1.

[0038] When the utility model is in use, when it is necessary to remove dust from the external air, the blower 12 is started, and the blower 12 absorbs the air in the shell body 1 through the bell mouth 13, so that the external dust-containing gas enters the shell body 1 through the air inlet nozzle 3 and the serpentine tube 11. The external dust-containing gas entering the shell body 1 first enters below the fixed plate 10, and the dust with excessive weight in the external dust-containing gas falls on the bottom wall of the shell body 1 under its own gravity, and the external dust-containing gas containing fine dust is filtered through the cloth bag 9. The cloth bag 9 can be used to filter the dust in the external dust-containing gas, and the air passing through the cloth bag 9 enters the blower 12 through the bell mouth 13, and the air absorbed by the blower 12 is discharged through the air outlet nozzle 2, thereby completing the filtration of the external dust-containing gas.

[0039] When the cloth bag 9 has been used for too long or is clogged with too much dust and needs to be replaced, the first sealing plate 4 can be opened, and then the locking bolt inserted on the sliding block 14 can be loosened, and the air in the inflatable airbag cover 16 can be discharged through the exhaust valve on the inflatable airbag cover 16. After the air in the inflatable airbag cover 16 is discharged, the inner ring diameter of the inflatable airbag cover 16 becomes larger. At this time, the fixing plate 10 can be moved up, and the cloth bag 9 can be removed from the inflatable airbag cover 16. At this time, the cloth bag 9 can be directly pulled out from between several clamping blocks 20. In addition, the present device can also be suitable for cloth bags 9 of different diameters and heights. By using the cooperation of the slider 18, the guide rail 17 and the spring 22, the position of the slider 18 on the guide rail 17 can be adjusted according to the diameter of the cloth bag 9. The elasticity of the spring 22 can be used to make the clamping block 20 clamp the cloth bag 9. The holding blocks 20 can clamp the cloth bag 9 together to complete the clamping and fixing of the bottom end of the cloth bag 9. Cloth bags 9 of different diameters can be clamped, and the inflation amount in the inflatable airbag cover 16 is different, and the inner circle diameter of the inflatable airbag cover 16 is also different. The inner circle diameter of the inflatable airbag cover 16 can be adjusted according to the diameter of the cloth bag 9, thereby completing the clamping and fixing of the inflatable airbag cover 16, and the height of the fixing plate 10 can be adjusted by the cooperation of the sliding block 14, the sliding groove 15 and the locking bolt inserted on the sliding block 14, and then the height of the fixing plate 10 and the inflatable airbag cover 16 can be adjusted according to the height of the cloth bag 9 to be installed, so that the device can be applicable to cloth bags 9 of different diameters and different heights, so that the device can be installed and used for cloth bags 9 of different diameters and different heights, thereby improving the convenience of the device when in use.
