Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to an automatic dust unloading device for bag dust collectors. Background Art

[0002] The bag filter is a dry dust filter device suitable for capturing fine, dry, non-fibrous dust. Its working principle is: when the dust-laden gas enters the ash hopper through the guide plate from the lower air intake duct of the dust collector, the coarse dust will fall into the ash hopper due to the collision of the guide plate and the reduction of gas velocity, and the remaining fine dust particles will enter the filter bag chamber with the gas. Due to the inertia, diffusion, barrier, hooking, static electricity and other effects of the filter material fibers and fabrics, the dust is retained in the filter bag, and the purified gas escapes from the bag and is discharged through the exhaust pipe.

[0003] Most of the dust removal devices for bag dust collectors in the prior art cannot realize automatic dust removal operation, and workers are required to manually complete the dust removal, which is complicated and troublesome, time-consuming and labor-intensive, reduces work efficiency, reduces practicality, and is inconvenient to use.
