Description

Technical Field

[0001] This utility model relates to the technical field of bag filters, and in particular to a circular bag filter that facilitates filter bag replacement. Background Technology

[0002] Circular bag filters are a commonly used dust removal device. They filter gas through filter bags to achieve dust removal. Currently, the air blowing pipe of the bag filter is connected to the dust collector cover, which means that when replacing the filter bag, the air blowing pipe and pulse valve must be completely disconnected, and the Roots blower connection pipe must also be disconnected before the bag filter cover can be opened. This involves a lot of disassembly, making filter bag replacement time-consuming. Utility Model Content

[0006] The bag filter housing has an open structure at the top and bottom. The bottom of the bag filter housing is equipped with a bottom connecting flange, and the top of the bag filter housing is equipped with a top connecting flange.

[0007] The bottom of the top cover is equipped with a cover flange.

[0008] The top cover has several reinforcing ribs inside.

[0009] Several channel steel pressure plates are fixed to the mounting plate by bolts, and two adjacent rows of filter bags are pressed together by a corresponding channel steel pressure plate.

[0010] The advantages of this utility model are: the top cover is separated from the bag filter housing, and the air inlet, air manifold, and purge pipe are all located on the bag filter housing, which makes it easier to open the top cover to disassemble and replace the filter bag, resulting in higher efficiency.
