Description

Technical Field

[0001] The utility model relates to the technical field of filter bag structures, in particular to an efficient dust removal filter bag. Background Art

[0002] A dust removal filter bag refers to a cloth bag equipped in a dust collector;

[0003] Among them, for a dust removal filter bag in a Chinese patent with the application number <2020216>60520.2>, the patent includes a filter bag body. One end of the filter bag body is provided with a bag mouth. A connection structure is arranged at the front end of the bag mouth. The connection structure includes a connection rope, a first connection column, a connection ball, a connection port and a limit opening. A bag cage is arranged inside the filter bag body. A connection ring is arranged at the end of the bag cage. A second connection column is arranged at the rear end of the connection ring. A positioning ring is arranged inside the second connection column. A chassis is arranged at the end of the second connection column. The filter bag body includes a fiber wear-resistant layer, an anti-static layer, a convex dust-proof layer and a concave dust-proof layer. For the dust removal filter bag described in the utility model, by arranging the connection structure, the installation and disassembly of the filter bag body can be completed more conveniently, thereby facilitating the cleaning of the filter bag body. At the same time, the durability effect of the filter bag body can be increased, and the use effect is better.

[0004] However, the above patent and existing filter bags are mainly composed of an external filter bag body and an internal support (bag cage). The dust removal effect is achieved through the filter bag body, and the filter bag body is put into the dust removal operation through the internal support. However, the designs of the filter bag body and the internal support in the above patent and existing filter bags are relatively simple. Affected by the air duct in the dust collector, deformation will occur. This requires improving the support material of the internal support to avoid the above problems. However, this will lead to too much contact between the support part and the filter bag, blocking the flowing air, thereby reducing the filtering effect; and when replacing the filter bag, the filter bag body and the internal support need to be taken out separately, which increases the operation time. Therefore, we propose an efficient dust removal filter bag. Summary of the Utility Model
