This utility model discloses a ceramic filter plate cleaning device, relating to the field of ceramic filter plate technology. It includes a water receiving tank with a baffle plate installed at its top and a pressure boosting pipe installed on one side of the baffle plate. The device comprises a water pump, a water storage tank, and a water receiving tank. The water pump draws water from the storage tank through a pumping pipe. The pump then transfers the water to a transmission pipe, which in turn transfers it to a connecting pipe. The connecting pipe then transfers the water to a pressure boosting pipe, which in turn transfers it to a spray nozzle. The spray nozzle pressurizes the water and sprays it out. The rapidly moving water washes the ceramic filter plate, dripping downwards. The water passes through the inner side of the filter screen and is guided through a water inlet. The water is then collected in the receiving tank. As the water level rises, the water passes through the inner side of a water outlet, which then transfers the water to the inner side of the storage tank, thus achieving water recycling and saving water for the user.
