[0002] Cartridge dust collectors have been around since the 1970s in Japan and some European and American countries. They offer advantages such as compact size, high efficiency, low investment, and easy maintenance. However, due to their small capacity, difficulty in combining them into high-volume units, low filtration velocity, and limited application, limited to industries such as grain and welding, they have not been widely adopted for many years. In recent years, with the continuous development of new technologies and materials, companies in Japan and the United States have made improvements to dust collector structure and filter media, leading to their widespread application in industries such as cement, steel, electricity, food, metallurgy, and chemicals.

[0003] Cartridge dust collectors use filter cartridges as filter elements or employ pulse jet technology. Cartridge dust collectors can be categorized by installation method, including oblique insertion, side-mounted, ceiling-mounted, and top-mounted. Cartridge dust collectors can be categorized by filter cartridge material, including long-fiber polyester, composite fiber, antistatic, flame-retardant, membrane-coated, and nanometer filter cartridges.

[0004] When the existing cartridge dust collector structure is in use, the filter holes are easily clogged when the filter cartridge filters dust for a long time, thereby reducing its filtering effect. Utility Model Content

[0028] Working principle: When using the modular cartridge dust collector structure, first, turn on the suction fan 3, which conveys dust-laden air into the box 1. After entering the box 1, the air is filtered by the filter cartridge 11 and discharged to the outside of the box 1, while the dust falls into the box 1. After filtering for a period of time, turn off the suction fan 3, and the dust accumulated at the bottom of the box 1 needs to be discharged;

[0029] Turn on the motor 5, which drives the auger shaft 6 to rotate. The dust enters the conveying cylinder 4 through the waste outlet 2. Under the transmission action of the auger shaft 6, the dust is transported to the dust outlet at the bottom for discharge. At the same time, the rotation of the auger shaft 6 drives the second bevel gear 17 to rotate, and the second bevel gear 17 drives the first bevel gear 16 to rotate. The first bevel gear 16 drives the second rotating shaft 15 to rotate, and the second rotating shaft 15 drives the cam plate 18 to rotate. When the protruding end of the cam plate 18 rotates to the connecting plate 20, the connecting plate 20 is pushed to make the movable rod 19 slide to the right and squeeze the reset spring 21. The movable rod 19 drives the circular gear 22 to rotate through the tooth block on the side wall, and the circular gear 22 drives the first rotating shaft 8 to rotate. Since the groove at the bottom of the bottom column 10 is stuck in the clamping piece 9 of the cross structure The outer wall and the bottom column 10 rotate synchronously, and the bottom column 10 drives the filter cartridge 11 to rotate and store force. When the protruding end of the cam disc 18 rotates past the connecting plate 20, under the action of the reset spring 21, the movable rod 19 quickly resets and drives the circular gear 22 to rotate and reset. The circular gear 22 drives the first rotating shaft 8, the clamping member 9 and the bottom column 10 to quickly rotate and reset, so that the filter cartridge 11 quickly rotates and resets. When the filter cartridge 11 rotates rapidly, centrifugal force is generated, so that the dust blocked on the filter cartridge 11 is thrown into the box body 1. During the whole process of the rotation of the auger shaft 6, the filter cartridge 11 removes the dust blocked in the mesh through multiple rapid rotations, thereby preventing the filter cartridge 11 from being seriously blocked while cleaning the dust, thereby reducing its filtering effect. After the dust is discharged, the motor 5 is turned off and the suction fan 3 is turned on.

[0030] After use, the filter cartridge 11 can be pulled out upwards, the sealing ring 13 on the surface of the filter cartridge 11 that fits against the inner wall of the slot 12 is removed, and the bottom column 10 is removed from the clamping piece 9, thereby facilitating the replacement or cleaning of the filter cartridge 11.
