Description

Technical Field

[0001] The utility model relates to the technical field of bag filters, and in particular to a combined bag filter. Background Art

[0002] Bag filter is a multi-purpose filtering equipment with novel structure, small size, simple and flexible operation, energy saving, high efficiency, closed operation and strong applicability. Bag filter is a new type of filtering system. The filter bag is supported by a metal mesh basket inside the bag filter. The liquid flows in from the inlet and flows out from the outlet after being filtered by the filter bag. Impurities are intercepted in the filter bag. After replacing the filter bag, it can continue to be used.

[0003] The existing devices have some disadvantages during use, for example: bag filters are common filtering equipment in industrial production, used to remove impurities in liquids or gases. Traditional bag filter designs often adopt a combined installation structure, that is, the filter bag is placed inside the filter and fixed by a series of fasteners such as screws and pressure plates. Although this design method ensures the stability and sealing of the filter bag to a certain extent, there are many inconveniences in fixing the screws and pressure plates in actual operation. Especially when the filter bag needs to be cleaned or replaced, users usually need to first remove a large number of screws and pressure plates that fix the filter bag. This process is not only time-consuming and labor-intensive, but may also cause fasteners to wear or lose due to frequent disassembly and assembly, increasing maintenance costs.
