Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a scraper-type self-cleaning filter. Background Art

[0002] A filter is a device that uses filter elements to directly intercept impurities in liquids, remove suspended solids and particulate matter, reduce turbidity, purify water quality, reduce system dirt, bacteria, algae, rust, etc., to purify water quality and protect the normal operation of other equipment in the system. It is widely used in chemical, food processing, water treatment and other industries.

[0003] After long-term use, impurities in existing filters will clog the filter screen, which will cause the filtering performance of the filter screen to decline and affect the flow rate of the water. The filter screen inside the filter needs to be replaced or disassembled and cleaned manually at regular intervals, which not only increases a lot of labor costs, but also increases certain equipment costs.

[0004] To this end, we propose a scraper-type self-cleaning filter. Utility Model Content
