Description

Technical Field

[0001] The utility model relates to the technical field of industrial dust removal, in particular to a 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] Traditional bag-type dust collectors usually use a single air spray method to drive the bag-type dust collector to vibrate after filtering to shake off the dust attached to the outer surface of the bag-type dust collector. However, when the gas flows under the bag during the air spraying process, the airflow will slowly decrease, resulting in a decrease in the amplitude of the vibration under the bag, making it difficult to achieve a good dust cleaning effect on the outer surface of the bag. Utility Model Content

[0004] The utility model aims to provide a bag dust collector to solve the problem that the dust on the lower outer surface of the traditional bag dust collector cannot achieve a good dust cleaning effect.

[0006] As a further solution of the utility model: a guide rail is provided at the connection between the positioning pulley and the fixed ring tube, and a filter bag is detachably connected to the lower part of the outer side of the vortex blade fixed ring through threaded rotation.

[0007] As a further solution of the utility model: a dust funnel is provided below the filter cabin, and four supporting legs are provided on the outer side of the dust funnel, and the four supporting legs are respectively located at four corners of the bottom of the filter cabin.

[0021] In this embodiment, when in use, the compressed air tank 3 is first started, and the gas in the compressed air tank 3 will intermittently jet into the fixed ring tube 8 through the air supply pipe 4 and the jet pipe 9 fixedly connected below the air supply pipe 4. When the jetted gas contacts the vortex fan 16, it will drive the vortex fan 16 to rotate. The rotating vortex fan 16 will drive the vortex fan blade fixing ring 15 fixedly connected on the outside to rotate at the bottom of the inner side of the fixed ring tube 8.
