The multi-stage filter plate is composed of a first-stage filter plate, a second-stage filter plate and a third-stage filter plate, the sizes of filter holes of the multi-stage filter plate are sequentially decreased, an embedding plate of the multi-stage filter plate is embedded into an embedding groove, water flows to a water collecting opening and then is filtered through a leakage net, impurities are blocked, and therefore the anti-blocking effect is achieved. Water generated by melting can be concentrated to the water collecting opening and then guided into the water receiving box through the drainage pipe, water residues are prevented, the water receiving box is additionally arranged, the connecting lugs on the left side face and
