The installation is stable and has a certain limiting function. The medium - efficiency bag - type filter component 2 can be replaced individually, avoiding the need to replace the entire bag - type filter module as a whole. At the same time, the position of the medium - efficiency bag - type filter component 2 can be locked by using the anti - loosening component 4 to prevent the medium - efficiency bag - type filter component 2 from loosening. And when replacing the medium - efficiency bag - type filter component 2, only a small number of disassembly and assembly bolts 46 need to be loosened to disassemble and assemble the medium - efficiency bag - type filter component 2, thereby making the replacement of the medium - efficiency bag - type filter component 2 more convenient, improving the replacement efficiency of the medium - efficiency bag - type filter component 2, and reducing the impact of the replacement time of the medium - efficiency bag - type filter component 2 on the medium - efficiency bag - type air filter.

[0052] The medium - efficiency bag - type filter component 2 includes an installation frame 21, and a medium - efficiency filter bag 22 is connected to the bottom of the installation frame 21.

[0053] In this technical solution, the medium - efficiency filter bag 22 is used to filter air.

[0054] The length of the installation frame 21 is less than the inner diameter length of the fixed outer frame 1.

[0055] In this technical solution, the installation frame 21 can be installed inside the fixed outer frame 1.

[0056] The disassembly and assembly component 3 includes a first gear 31 and a second gear 32, and the first gear 31 and the second gear 32 are meshed and connected to each other;

[0057] On the opposite sides of the first gear 31 and the second gear 32, a moving rack 33 is meshed and connected;

[0058] One side of the moving rack 33 is connected to a connecting column 34, and the end of the connecting column 34 away from the moving rack 33 is connected to the side of the installation frame 21.

[0059] In this technical solution, the first gear 31 and the second gear 32 can respectively drive the moving rack 33 to move synchronously, thereby moving the installation frame 21, which is more convenient for the installation and disassembly of the medium - efficiency bag - type filter component 2.

[0076] The bottom of the locking rack 43 is connected with a plurality of elastic reset components 47, and the bottom ends of the elastic reset components 47 are connected with the bottom of the inner cavity of the protective housing 45.

[0077] In this technical solution, when the disassembly and assembly bolt 46 is loose, the elastic reset component 47 can be used to make the locking rack 43 move along with the movement of the installation cover plate 44.

[0078] After the medium-efficiency bag filter component 2 is installed, the installation cover plate 44 is locked on the top of the protective housing 45 by using the disassembly and assembly bolt 46. At this time, the locking rack 43 moves along with the movement of the installation cover plate 44. When the installation cover plate 44 is locked on the protective housing 45, the locking rack 43 is in close contact with and engaged with the locking gear 42, thereby locking the angles of the first gear 31 and the second gear 32, and enabling the medium-efficiency bag filter component 2 to be stably installed;

[0079] When it is necessary to disassemble the medium-efficiency bag filter component 2, first loosen the disassembly and assembly bolt 46. At this time, under the action of the elastic reset component 47, the locking rack 43 moves away from the locking gear 42. At this time, the first gear 31 and the second gear 32 can be rotated by using the rotating disk 36 to disassemble the medium-efficiency bag filter component 2.
