[0002] Bag dust collector is a dry dust filtering device, which is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter dust-containing gas. When the dust-containing gas enters the bag dust collector, the large particles and high specific gravity dust settle due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

[0003] The existing announcement number is CN210473335U, and the name is a bag-type dust collector for collecting dust, comprising a shell, a plurality of cloth bags are installed inside the shell, a dust suction pipe is connected to the right side of the shell, a flange is connected to the right end of the dust suction pipe, a collection pipe is vertically welded at the bottom of the dust suction pipe, and a material blocking mechanism is installed on both the dust suction pipe and the collection pipe, and the material blocking mechanism includes a fixing plate, a handle and a baffle, and a limit block and a limit sleeve are installed inside the dust suction pipe and the collection pipe; a vibration damping cavity is arranged in the shell, and a plurality of vibration damping blocks are installed inside the vibration damping cavity, and the vibration damping block includes two symmetrically arranged rubber blocks, three groups of springs are arranged between the two rubber blocks and connected by the springs, a rubber plate is arranged on the surface of the rubber block, and the rubber plate is connected to the inner wall of the vibration damping cavity by glue bonding, the dust collector has a collection pipe installed at the bottom of the dust suction pipe, and a filter net is fixed in the dust suction pipe, which can filter larger debris, and when the work stops, the debris automatically falls into the collection pipe, which is convenient for cleaning.

[0004] However, when the above-mentioned bag filters and removes dust in the air, the dust will adhere to the bag. A lot of dust will accumulate in the bag for a long time. The dust falls by its own gravity, and the dust falling rate is slow. The thick dust accumulated on the bag not only blocks the air vents on the bag, but also affects the air circulation rate.
