Description

Technical field: [0001] The invention is a vertical backwash filter suitable for filtering impurities in water in water systems such as power plants, iron and steel, papermaking, and plumbing. Background technique: [0002] At present, the vertical filter for filtering impurities in water is installed with a filter screen in a vertical filter cartridge, and the water containing impurities is filtered by a high-inlet and low-out method, and the impurities are intercepted on the filter screen in the filter cartridge. , to achieve the filtering effect. The main disadvantage of this traditional vertical filter is that when the filtered impurities reach a certain amount, the filter screen needs to be taken out from the filter cartridge to clean the screen, which is not only inconvenient to disassemble, but also damages the filter The tightness and filter screen will have a certain impact, reducing the service life of the filter.
