Description

Technical Field

[0001] The utility model belongs to the technical field of bag dust collectors, and particularly relates to an anti-blocking bag dust collector. Background Art

[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 the dust-containing gas. When the dust-containing gas enters the bag dust collector, the large particles and high specific gravity dust settle down 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] A Chinese patent with publication number "CN219897413U" discloses a bag-type dust collector, which belongs to the technical field of dust collectors, and includes a bag-type dust collector body and a cleaning structure arranged on the surface of the bag-type dust collector body, and a pushing structure for driving the cleaning structure; a pulse valve body is installed on the surface of the bag-type dust collector body; the utility model, by setting a cleaning structure, when an operator uses the device and needs to disassemble and replace the filter bag body inside the bag-type dust collector body, the fixing structure is adjusted first, and when the fixing structure is released from the fixing state with the bag-type dust collector body, the operator pulls the installation sleeve, and with the cooperation of two reinforcement plates, the ventilation sleeve can simultaneously drive all the installation sleeves to rotate to a state perpendicular to the ground.

[0004] However, this device still has some shortcomings. When the bag dust collector is running, it will absorb a large amount of dust. Although the bag dust collector has the function of dust absorption and filtering, after long-term use, the larger dust will block the inside of the air inlet pipe of the bag dust collector. Since the position of the air inlet pipe connection is inconvenient to disassemble, the user needs to open the entire body and then clean the blocked areas inside, thereby reducing the maintenance efficiency of the bag dust collector.
