[0002] When dewatering sludge, flocculants need to be added to the sludge, and the sludge and flocculants are mixed by stirring to produce a flocculation reaction, thereby separating the sludge from the water. The sludge is then dewatered by other equipment such as a mud press. During the transportation of the treated sludge, the existing stirring device often hinders the transportation of the sludge, making it inconvenient to transport the sludge, increasing the complexity and difficulty of the operation.
