Description

Technical Field

[0001] The utility model relates to the field of dust collectors, and specifically relates to a filter element for a pulse dust collector. Background Technique

[0002] The pulse dust collector is a new type of high-efficiency pulse dust collector improved on the basis of the bag dust collector. It usually consists of a metal mesh skeleton, a filter mesh cover wrapped around the circumferential surface of the metal mesh skeleton, and end caps bonded to both ends of the filter mesh cover. It uses high-pressure pulse gas to blow back, purge, and shake off the dust attached to the surface of the dust collector, so that its filtration area reaches more than 3 times that of ordinary filter bags under the same volume, greatly reducing the floor area of the dust collector.

[0003] However, since the filter element of the dust collector is generally cylindrical, the surface area facing upwards of the filter element is relatively large, and more dust falls on the surface of the filter element. It is also very difficult to purge it cleanly using a conventional pulse valve for back blowing. Therefore, the utility model proposes a filter element for a pulse dust collector, which adopts a combined structure. On the one hand, it is convenient for disassembly and assembly, and can ensure its service life by regularly disassembling and cleaning the filter element. On the other hand, it is provided with structures such as an electromagnet and a magnetic block. The electromagnet can adsorb or repel the magnetic block when powered on and started. At this time, the telescopic block is in an extended or contracted state, and the telescopic tube will also move accordingly. By the above means, the filter element can be vibrated / shaken, and the dust adsorbed on the filter element can be shaken off before the filter element is back blown, making the back blowing dust removal more convenient.
