Description

Technical Field

[0001] The utility model belongs to the technical field of large-flow low-pressure filters and relates to a filter with a large-flow low-pressure structure. Background Art

[0002] High-flow, low-pressure filters are specially designed to handle impurities and particulate matter in high-flow, low-pressure fluids. Widely used in various industrial fields, high-flow, low-pressure filters are distinguished by their ability to process large volumes of fluid at relatively low pressures. This design allows the filters to meet the demands of large-scale production without increasing energy consumption or costs. However, failure to improve filtration and flow diversion efficiency can lead to serious problems that not only affect the normal operation of the equipment but can also negatively impact the production process and product quality.

[0003] Low filtration efficiency means that the filter cannot effectively intercept impurities and particulate matter in the fluid. In the existing technology, the filter adopts a direct filtration structure. However, when the direct filtration structure processes large-flow, low-pressure fluids, as the impurities increase, these unfiltered impurities will continue to flow with the fluid, which may cause blockage to subsequent equipment or process links. It requires a long period of shutdown to disassemble the equipment and replace the filter element, increasing the maintenance cost and downtime of the equipment. Therefore, there is an urgent need for a filter with a large-flow, low-pressure structure to solve the above problems. Utility Model Content
