Sludge drying tank capable of sufficient drying

The invention provides a sludge drying tank capable of sufficient drying. The sludge drying tank comprises a heat preservation tank body. The heat preservation tank body is provided with a feeding hopper, a heating box, an air pump, a collecting and drying device, conveying devices, a spray head, a cleaning device, a feeding box, an auger, a motor B and a water outlet pipe. By arranging the feeding box and the packing auger, part of water in the sludge can be extruded into a water receiving box, and the subsequent drying load can be reduced; meanwhile, through arrangement of three conveying devices and a stirring paddle in the collecting box, the sludge can be sufficiently dried; finally, through arrangement of the cleaning device, the sludge adhered to the conveying devices can be cleaned, and the influence of sludge adhesion on the operation of the conveying devices is avoided. 本发明是一种烘干充分的污泥干化箱，包括保温箱体，保温箱体上设有进料斗、加热箱、气泵、收集烘干装置、输送装置、喷头、清洁装置、送料箱、绞龙、电机B和出水管。本发明通过设置送料箱和绞龙可以将污泥中的部分水分挤出至接水箱，能够降低后续烘干的负荷；同时三个输送装置以及收
