Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and in particular, to a bag filter dust collection device. Background Technology

[0002] A baghouse dust collector is a dry filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, large and heavy dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter bags, the dust is trapped, thus purifying the gas.

[0003] After a period of use, the dust collection bags inside a baghouse dust collector accumulate a large amount of dust on their surface, affecting the dust collection efficiency. Therefore, regular dust removal is necessary. Current methods typically employ pulse-jet cleaning for dust removal. These pulse-jet units are usually installed directly inside the baghouse dust collector. The unit injects compressed air into the dust collection bags through venturi tubes, removing the dust adhering to the bag surface. This method is simple to operate, highly automated, and requires minimal labor.

[0004] However, in the above methods, the dust collection bag is relatively long, and the airflow generated by the pulse is prone to insufficient energy after reaching the lower end of the dust collection bag, which results in the dust on the dust collection bag not being completely removed, thus reducing the dust filtration effect of the dust collection bag.

[0027] The dust removal assembly 3 also includes a connecting post 34. There are two dust removal components 32. Both dust removal components 32 can be slidably sleeved on the outside of the guide post 31. The connecting post 34 is used to connect the two dust removal components 32. Specifically, one end of the connecting post 34 is fixedly connected to the upper dust removal component 32, and the other end of the connecting post 34 is fixedly connected to the lower dust removal component 32.

[0028] Furthermore, there are multiple cleaning pipes 33, with two cleaning pipes 33 corresponding to each cleaning component 32, and the two cleaning pipes 33 are arranged opposite to each other. Each cleaning pipe 33 includes a connecting section 331, a flexible hose section 332, and an air inlet section 333 that are connected to each other. The flexible hose section 332 is located between the connecting section 331 and the air inlet section 333. The connecting section 331 is fixedly connected to the cleaning component 332, and the air inlet section 333 is fixedly connected to the side wall of the dust collector body 1. In this embodiment, both the connecting section 331 and the air inlet section 333 are rigid pipes, which can increase the connection stability between the connecting section 331 and the cleaning component 32, and between the air inlet section 333 and the dust collector body 1.

In other embodiments not shown, the driving component 35 may also be an electric push rod; this is not a limitation, as long as the driving component 35 can drive the dust removal component 32 to slide longitudinally along the length direction of the guide rod 31.

[0034] When it is necessary to filter dust from the main body 1 of the dust collector, the gas first enters the cleaning cylinder 321 through the cleaning pipe 33, and then flows out through the cleaning ring 322 to filter dust from the outer surface of the filter bag 2. Then the drive component 35 is activated, and the drive component 35 drives the cleaning component 32 to slide downward along the length of the guide rod 31, so that all the dust attached to the surface of the entire filter bag 2 can be removed.

[0035] The dust collector and filter device provided by this utility model filters dust from the outer surface of the filter bag 2 by setting a dust removal component 32. The dust removal component 32 can slide longitudinally along the length direction of the guide rod 31, thereby avoiding the phenomenon of insufficient energy when the air flow generated by the pulse reaches the lower end of the dust collector bag. Therefore, the dust on the filter bag 2 can be completely removed, improving the dust filtration effect of the filter bag 2.
