The invention discloses a sludge output device based on chemical feeding and stirring, and belongs to the technical field of environmental protection equipment. The sludge output device based on chemical feeding and stirring is composed of a bottom box, a top cover plate and a stirring device, wherein a water inlet and a raw sludge inlet are formed in one side of the bottom box, an output openingis formed in the other side of the top cover plate, and a bottom partition board is arranged in the middle of the bottom box; a top partition board is connected to the bottom of the top cover plate, and the top partition board and the bottom partition board are arranged in a staggered mode and divide an internal cavity into three rectangular spaces; the top cover plate is composed of a first stirring mechanism, a second stirring mechanism and a third stirring mechanism from left to right in sequence, and the stirring mechanisms are correspondingly arranged in the three rectangular spaces formed by the partition boards through division respectively. The sludge output device is novel in structure with a clear working principle. Compared with traditional sludge stirring device structures, thesludge output device has the advantages that manufacturing is convenient, the cost is low, curing operation time is short, quick stirring of raw sludge and chemicals can be achieved, stirring efficiency is improved greatly, and a solid foundation is laid for the next step of sludge treatment.
