Description

Technical Field

[0001] The utility model relates to the technical field of dust collecting equipment, in particular to a pulse back-flushing industrial dust collecting equipment. Background Art

[0002] Various dusts are generated in the production process of industries and other fields. Some of these industrial dusts contain various metal components, and some contain various wood chips, paper scraps, etc. If these industrial dusts are allowed to be released into the air environment, they will not only damage the surrounding air quality, but also endanger the health of operators who breathe these dusty air for a long time. Therefore, dust collection equipment is needed to remove dust from the air. Dust collector is a device that collects suspended dust and dust-like floating objects from the air. It is mainly installed at the exhaust port of the air delivery and masterbatch system to prevent dust and dust-like floating objects from entering the atmosphere, avoiding serious air pollution, and playing a role in environmental protection.

[0003] Most of the dust collection equipment on the market sends dusty air directly to the filter cartridge through the DC air inlet on the outside of the box during filtering. This will cause the filter cartridge to be impacted by high-velocity gas, which will greatly reduce the service life of the filter cartridge. After the filter cartridge of the dust collection equipment is used for a long time, dust will adhere to the filter cartridge, causing the filter cartridge to be blocked. In the past, workers directly disassembled the filter cartridge for cleaning, which was time-consuming and labor-intensive, and increased labor costs.
