Description

Technical Field

[0001] The utility model relates to the technical field of filter cartridge dust collectors, and more specifically to a filter cartridge dust collector which is convenient for replacing filter cartridges. Background Art

[0002] Cartridge dust collectors are composed of filter cartridges as filter elements or use pulse jets. Cartridge dust collectors can be divided into oblique insertion type, side-mounted type, hanging type, and top-mounted type according to the installation method. Cartridge dust collectors can be divided into long fiber polyester cartridge dust collectors, composite fiber cartridge dust collectors, antistatic cartridge dust collectors, flame retardant cartridge dust collectors, membrane cartridge dust collectors, nano cartridge dust collectors, etc. according to the cartridge material.

[0003] After searching, the existing patent number CN218188641U is a filter cartridge dust collector that is easy to replace the filter cartridge, including a dust box, a disassembly opening is opened at the front end of the dust box, a mounting plate is fixedly arranged inside the disassembly opening, a symmetrical mounting frame is fixedly arranged at the left end of the inner wall of the dust box, filter tubes are horizontally arranged inside the two mounting frames, an annular plate is fixedly arranged at the left end of the two filter tubes, a filter screen is fixedly arranged inside the annular plate, and two identical filter devices are arranged inside the dust box. When a lot of dust accumulates on the surface of the filter screen inside one filter device and needs to be cleaned, the position of the connecting pipe can be quickly rotated to connect with the other filter device, and then the filter device that needs to be disassembled can be disassembled and assembled. The whole process is relatively simple and fast, and will not delay the time of air purification. The filter tube is easy to disassemble and install.

[0004] For common filter cartridge dust collectors, after the filter cartridge is plugged into the housing, it is locked and fixed by a locking piece. After a period of use, the dust filtered on the surface of the filter cartridge is affected by the resistance at the connection between the filter cartridge assembly groove and the filter cartridge. After disassembling the locking piece, the filter cartridge is not convenient to pop out, and the removal process is relatively laborious, reducing the replacement efficiency. Therefore, we propose a filter cartridge dust collector that is easy to replace the filter cartridge to solve the above-mentioned problems. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a filter cartridge dust collector which is easy to replace the filter cartridge. When installing the filter cartridge body, hold the end of the filter cartridge body with the cover plate, and first plug the end of the filter cartridge body with the pressure ring into the assembly groove of the casing until the cover plate fits in the opening position of the assembly ring. At this time, the spring between the filter cartridge body and the pressure ring undergoes elastic deformation, and the cover plate is screwed to plug into the assembly ring. At this time, the installation of the filter cartridge body is completed; when the filter cartridge body needs to be disassembled and replaced, the cover plate is screwed in the opposite direction to separate from the assembly ring. Under the elastic force of the spring, the filter cartridge body pops out to the outside relative to the assembly groove, thereby reducing the resistance generated by the filtered dust, facilitating disassembly and replacement, and improving assembly efficiency.
