Double-layer filter tank structure

The utility model provides a double-layer filter tank structure, which relates to the field of filter tank equipment and comprises a first filter tank, a pipeline, a valve, a second filter tank and two collecting components, one sides of the two collecting components are respectively and fixedly connected with one sides in the first filter tank and the second filter tank, and the valve is mounted at the center of the pipeline. The two ends of the pipeline are fixedly connected with the opposite sides of the first filter tank and the second filter tank respectively, the driving assembly drives the driving plate to move, so that the driving plate drives the transmission brush plate to move on the transmission rod through the transmission connecting plate, and silt and calcium carbonate at the bottoms of the first filter tank and the second filter tank are cleaned into the collecting part; through the structure, automatic collection of silt and calcium carbonate is achieved, the labor intensity of workers is red
