Blending tank with filtering device

The invention discloses a blending tank with a filtering device, and relates to the field of blending tanks. The blending tank with the filtering device comprises a tank body, a filtering shell is installed at the bottom of the back face of the tank body, a slag collecting filtering plate, a filtering net plate and a non-woven fabric filtering plate are sequentially and transversely installed in an inner cavity of the filtering shell from top to bottom, and a liquid suction pump is arranged at the top of the filtering shell. According to the blending tank with the filtering device, blending materials needing to be blended are injected into the filtering shell through an external pipeline, impurities and large particles of the blending materials are filtered out through the slag collecting filtering plate, fine particles and impurities in the blending materials are filtered out again through the filtering net plate and the non-woven fabric filtering plate in sequence, and the blending materials are filtered ou
