Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a bag dust collector with convenient bag replacement. Background Art

[0002] The dust bag can be regarded as the heart of the bag dust collector. It is generally called a dust bag or a dust filter bag. The dust bag is a key part in the operation of the bag dust collector. Usually the cylindrical filter bag is hung vertically in the dust collector. The fabric and design of the dust bag should strive for high-efficiency filtration, easy dust removal and durability. The selection of the dust bag is crucial, which directly affects the dust removal effect of the bag dust collector.

[0003] The dust bags of bag-type dust collectors and their mounting frames are currently generally fixed with bolts. Although this connection method ensures the firmness of the connection, it brings inconvenience to disassembly in actual operation, especially when the dust bags need to be quickly replaced or repaired. The removal and installation process of the bolts can be cumbersome. In addition, the existing dust bag designs are sometimes not fully deployed according to actual dust removal needs during use, which to some extent limits the efficiency and practicality of the bag-type dust collector, making its effect in actual application fail to achieve the best state. Therefore, for the design and improvement of bag-type dust collectors, we need to focus on how to simplify the disassembly process of the dust bags and how to improve the deployment efficiency of the dust bags, so as to further improve the practicality and performance of the bag-type dust collectors.

[0004] Therefore, it is necessary to provide a new bag filter that is convenient for replacing bags to solve the above technical problems. Utility Model Content

[0014] Preferably, surfaces of the two snap blocks close to the positioning block are provided with rounded corners.

[0015] When the extrusion rod squeezes the buckle block, the buckle block will not completely move out of the rectangular groove on the side of the positioning block.
