Description

Technical Field

[0001] The utility model relates to the field of bag dust collectors, in particular to a self-cleaning mechanism of bag dust collectors. Background Art

[0002] The bag filter is a dry dust filter. It 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 filter, the large particles and heavy 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] After searching the patent document with the announcement number CN219043183U, the patent document discloses "a boiler bag dust collector with a self-cleaning structure, in which the limit block moves downward to drive the rotating rod to move downward, and the rotating rod moves downward to drive the transmission gear to move downward, at this time, the transmission gear rotates due to the meshing force of the transmission rack, and the rotation of the transmission gear drives the rotating rod to rotate, and the rotation of the rotating rod drives the self-cleaning film roller to rotate, so that the self-cleaning film roller can be attached to the outer wall of the dust filter bag while rotating and moving downward, so that the solid dust on the outer wall of the dust filter bag can be adhered to more cleanly, and this structure is beneficial to quickly adhere the solid dust on the outer side of the dust filter bag through the self-cleaning film roller, so as to increase the dust filter bag's treatment effect on flue gas";

[0004] When the above-mentioned device cleans the filter structure, although one end of the dust filter bag is cleaned by the self-cleaning film roller, referring to the attached figure of the above-mentioned device, the main filtering end face of the dust filter bag is the end face on which the self-cleaning film roller is installed, and the passing gas is secondary filtered through the other end of the dust filter bag. In this way, the dust filter bag of the above-mentioned device can clean the main filtering end face by the self-cleaning film roller, while the other end and other end faces of the dust filter bag are not provided with cleaning structures. This may easily lead to the situation that the other filtering end faces of the dust filter bag of the above-mentioned device are blocked due to excessive dust accumulation after long-term use.
