Scraper filter


1. Working Principle and Structural Characteristics

The automatic scraper filter has a linear filter with automatic cleaning structure. The filter parts are made of Johnson filter with high strength, so it has the advantages of large filtering area and easy cleaning. When the pressure difference between the inlet and outlet of the filter reaches a certain value, the backwashing system of the filter starts to operate automatically. The motor drives the stainless steel brush to rotate. The impurity particles are brushed down from the inner wall of the filter by the rotating steel brush, and then discharged by the discharge valve to achieve the cleaning purpose. In the whole process of filtering and cleaning, the material flow continuously, realizing continuous and automatic production. Fully automatic scraper filter is our patent product (patent number: 97243360.0).
