Description

Technical Field

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

[0002] The filter is a multi-purpose filtering equipment with novel structure, small size, simple and flexible operation, energy saving, high efficiency, closed working and strong applicability. The filter bag is supported by a metal mesh basket inside the 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 and it can continue to be used after replacing the filter bag.

[0003] When installing the existing filter bag, the pressure plate is usually pressed against the filter bag, and then the pressure plate and the sleeve are fixed by bolts. This results in the need to manually remove the bolts one by one when replacing the filter bag, which is cumbersome and inconvenient to replace the filter bag. In order to solve the above problems, a filter bag is proposed. Utility Model Content
