Description

Technical Field

[0001] This utility model relates to the field of basket filtration technology, and specifically to a basket filter. Background Technology

[0002] Basket filters are used in oil or other liquid pipelines to filter out impurities. The filter pore area is 2-3 times larger than the pipe diameter. The filter screen structure differs from other filters; it is named a basket because of its basket-like shape. Basket filters mainly consist of connecting pipes, a cylinder, a filter basket, flanges, flange covers, and fasteners. Installed on pipelines, they remove larger solid impurities from fluids, ensuring the normal operation of machinery and instruments, stabilizing the process, and guaranteeing safe production.

[0003] Existing basket filters typically use a filter basket to filter impurities. When the basket filter needs to be cleaned, the flange cover needs to be disassembled manually for cleaning. Since the fluid flowing inside the basket filter may be corrosive, it is easy to cause injury to personnel during the maintenance and cleaning of the basket filter. Furthermore, when the internal filter cartridge needs to be cleaned after long-term use, it is also inconvenient to remove the filter cartridge. Utility Model Content
