Abstract

The utility model discloses a self-cleaning filter. The self-cleaning filter comprises a filter shell body. A water inlet tube is disposed at the bottom of the filter shell body and a water outlet tube is disposed at the top of the filter shell body. An upper layer filter screen and a lower layer filter screen are installed inside the filter shell body. A cavity between the upper layer filter screen and the lower layer filter screen is filled with steel balls. An upper cavity formed by the upper layer filter screen and the filter shell body is communicated with the water outlet tube hermetically. A lower cavity formed by the lower layer filter screen and the filter shell body is communicated with the water inlet tube hermetically. When a certain amount of impurities are accumulated, the filter starts a self-cleaning process. A pneumatic butterfly bamper is opened, and then water flows through the water inlet tube and washes the upper layer filter screen, the lower layer filter screen and filtered material parts. Because the filtered material parts are stainless steel balls, impurities adherent to surfaces of the filtered material parts are relatively easy to eliminate. When cleaning is finished, the pneumatic butterfly bamper is closed and next circle of work is restarted. The self-cleaning filter is simple in structure and good in cleaning effect.
