Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a multi-layer filtering cloth 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] The patent with announcement number CN220071047U discloses a bag dust collector, including a cylinder and a cone connected to the bottom of the cylinder, an air inlet pipe connected to the inside of the cylinder is arranged in the middle of the side wall of the cylinder, a partition is arranged above the air inlet pipe at the inner cavity of the cylinder, a cyclone is arranged in the middle of the bottom of the partition, a central tube is arranged on the outside of the cyclone, and an air guide structure is arranged in the middle of the upper surface of the partition. This bag dust collector realizes the dual functions of swirl and filtration through the cooperation between the cyclone and the filter bag, so that larger dust particles can fall directly into the ash bin under the action of centrifugal force, or form fine dust by colliding with the wall of the device and being filtered by the filter bag. At the same time, the two complement each other, making the best use of their strengths and avoiding their weaknesses, greatly improving the dust removal efficiency.

[0004] However, due to the above-mentioned bag-type dust collector, when connecting the bag-type dust collector and the dust outlet pipe of the incinerator, it is not clear how the bag-type dust collector is connected to the dust outlet pipe of the incinerator. If it is fixed with the existing more common bolts, the connection between the dust outlet pipe and the bag-type dust collector needs to be checked every day to prevent the bolts from loosening and causing the dust outlet pipe to fall off, which is rather cumbersome. Therefore, we propose a multi-layer filtering bag-type dust collector to solve the above problem. Utility Model Content
