Technical Field

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

[0002] A filter screen, or simply filter mesh, is made of metal wire mesh with different mesh sizes. Its function is to filter molten material flow and increase flow resistance, thereby removing mechanical impurities and improving the mixing or plasticizing effect. Filter screens have a wide range of applications, commonly used for filtering solid impurities in liquids. They can effectively isolate particulate fixed or suspended matter in liquids and have significant uses in both domestic and industrial applications.

[0003] Metal filters are made of metal. Compared to flexible filters, metal filters are more robust and durable, allowing for long-term use. However, to ensure filtration effectiveness, metal filters are typically fixed inside the filtration equipment. With continuous use, a large amount of solid debris accumulates on their surface, affecting their filtration efficiency. Therefore, regular cleaning is necessary. However, most metal filters have a fixed shape and cannot be folded or disassembled, making thorough cleaning impossible and impacting their normal filtration performance. Utility Model Content
