Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to an internal scraper self-cleaning filter. Background Art

[0002] A filter is an important device that is mainly used to remove impurities or unwanted substances from fluids (liquids or gases) to achieve the purpose of purification. It is widely used in various industrial production and daily life, such as water treatment, air purification, food processing and other fields. The working principle of the filter is mainly divided into physical filtration and chemical filtration. Physical filtration mainly uses the pores or filter materials in the equipment to screen out larger solid particles or other impurities. For example, the mesh filter on a household faucet is a common physical filter that can block impurities such as sand and leaves in the water.

[0003] In the prior art, after long-term use, the internal filter screens of most filters are easily clogged by impurities, which reduces the filtering quality of the filters and requires manual replacement of the filter screens, which not only increases the workload of the staff, but also makes the filtering quality of the filters poor, thus affecting subsequent use.
