Description

Technical Field

[0001] This utility model belongs to the field of filter technology, and in particular relates to a filter with a self-cleaning filter screen function. Background Technology

[0002] In the industrial sector, filters are primarily used to remove impurities from raw materials, semi-finished products, or finished products to improve product quality. They are typically used to remove suspended solids, particulate matter, microorganisms, and other impurities from liquids, and are widely used in water treatment, chemical production, and food processing. For example, in the petrochemical industry, filters can remove water and solid particles from oil products, ensuring their purity.

[0003] For example, Chinese patent CN218458827U discloses a cooling water circulation filter, including a housing with an outlet pipe inside. A top cover is attached to the housing, and a disassembly mechanism is located inside the top cover. An anti-clogging mechanism with a filter screen is installed inside the housing, and an inlet pipe is also located inside. This invention utilizes components such as a motor, a first gear, a second gear, a rotating rod, a connecting plate, and a bevel ring to allow water to enter the housing through the inlet pipe. Starting the motor drives the first gear to rotate, which in turn rotates the connecting block and other components. The rotation of the connecting block causes the bevel ring and filter screen to move up and down, reciprocating to prevent clogging of the filter screen.

[0004] The aforementioned patent has the following problems:

[0005] This patented filter has some drawbacks in use. For example, while it can clean clogged screens, it only does so by moving the screen up and down. This method is insufficient to remove all impurities, potentially leading to further clogging. Therefore, we propose a filter with a self-cleaning function. Utility Model Content
