Description

[0001] The utility model relates to dust removal device technical field, concretely is a filter cartridge type industrial dust removal device. BACKGROUND

[0002] As high -efficient filter element, filter cartridge is divided into two big categories in industrial field mainly gas filtration and liquid filtration. Its filter medium adopts wood pulp fiber filter paper or spun -bonded method polyester fiber non -woven material, wherein the polyester non -woven cloth can be given the characteristics such as oil -proof waterproof, antistatic through surface coating process. In industrial dust removal system, this kind of filter cartridge is widely used in dust gas treatment, and three -dimensional filter structure formed through fiber layer realizes dust capture. The current installation mode generally adopts the threaded connection fixed in the dust remover flower board, relies on the threaded structure of the end of the cylinder and is rotated into the reserved hole position of the fixed plate, and the airtightness connection with the dust remover box is realized with the help of rubber sealing ring;

[0003] The threaded connection structure exposes significant defects in actual maintenance. Since filter cartridge needs to be disassembled regularly to check filter medium integrity, the screwing mode causes single filter cartridge to take 5-8 minutes to disassemble, and in the repeated disassembly process, the thread is easy to be abraded to cause sealing failure. More seriously, the rotating action of the cylinder can produce friction with the accumulated dust, which can accelerate the mechanical damage of the film layer on the surface of the filter medium. This installation mode not only reduces the maintenance efficiency, but also can cause secondary pollution, and therefore we propose a filter cartridge type industrial dust removal device.
