Abstract

The utility model relates to a continuous sand filter. Impure fine sand is conveyed onto a baffle plate on the side wall of a first separator tank at the upper end of a barrel tank body by a sand conveying pipe to separate sand particles from impurities and reduce the impact of spouted fine sand. Because of the different specific gravity of the sand particles and the impurities, the lightest impurities float on the water surface and flow into a shallow groove through the notch of the separating surface on the inner side of the shallow groove and are exhausted by an output pipe, and heavier impurities are exhausted through the output pipe at the bottom of a deep groove. The fine sand drops into a second separator tank through the outlet at the bottom of the first separator tank, and the fine sand is further separated by an empty pressure pipe, so that the fine sand with the impurities can be separated from the impurities, and the impurities flow into the tank body through the notch of the separating surface of the tank body and are exhausted through the output pipe. Thus, the efficiency of continuously cleaning water quality can be realized.
