Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a multi-filter element backwashing filter. Background Art

[0002] A multi-element backwash filter is a device used for water treatment and liquid filtration. It usually contains multiple filter elements, each of which can capture impurities and particulates of different sizes and types. This design can provide a larger filtration surface area and higher filtration efficiency. The backwash filter cleans the filter element by reverse flow of liquid to remove accumulated dirt on the filter element, extend the service life of the filter element, and ensure the continued efficient operation of the filter. This type of filter is usually used in industrial production, water treatment plants, swimming pools and other occasions that require large flow and high efficiency filtration.

[0003] When replacing the filter element of a general multi-filter element backwash filter, it is necessary to disassemble the cylinder and then replace the filter element. The process is cumbersome and wastes a lot of time. In order not to interrupt the filtering work and improve the working efficiency, the general multi-filter element backwash filter will perform a separate backwash on each filter element to clean the filter element. After cleaning the filter element for many times, it is difficult for the sewage pipe and the filter element interface to fit tightly, and gaps are likely to appear, resulting in poor cleaning effect. Pollutants may overflow from the gaps and then flow back into the filter element for repeated filtration. In view of the above problems, a multi-filter element backwash filter is proposed to solve them. Utility Model Content
