An elastic spring acts on the anti-backflow plate, preventing backflow and blockage of the feeding pipe when the cement grinding aid supply stops. The cement grinding aid in the feeding pipe enters a filter cylinder, where it is filtered to effectively remove particulate impurities, improving the impurity-free effect of the cement grinding aid and enhancing the quality of subsequent cement production. The intercepted impurities are placed in the filter cylinder for easy subsequent impurity treatment. In subsequent processing, a hydraulic cylinder is activated, pushing a fixedly connected slip ring to move. The slip ring then moves a fixedly connected extrusion filter, which, with the assistance of an extrusion plate, easily squeezes out impurities and removes residual cement grinding aid, preventing waste, saving costs, and meeting usage requirements.
