The device feeds water-based paint through a feed port, and then the water-based paint is filtered through a filter plate to filter impurities therein. Then the filtered water-based paint falls to the bottom of the filter box due to gravity, and then the discharge port can be opened by a control valve to discharge the paint. When the paint is discharged, clean water can be injected through the feed port, and then the motor is started to drive the threaded rod to rotate. The threaded rod rotates and pushes the threaded ring to drive the sliding ring and the cleaning brush to move to clean the filter plate. Then the baffle can be opened by the first handles on both sides to discharge the cleaned impurities, and the sewage can be discharged through the discharge port.
