[0002] In recent years, as the society pays more and more attention to environmental protection, the comprehensive management of rivers and lakes has been strengthened. Among them, the silt produced by dredging is a kind of engineering waste soil with high water content, which has fine particles and high organic matter content. It is in a flowing state and has almost no strength. How to dispose of it for resource utilization is the current research direction in the industry. In addition, the engineering construction materials required for land reclamation were mainly solved by mining the surrounding mountains in the past, which not only destroys the natural environment, but also Moreover, the heavy stone material increases the cost and difficulty of foundation treatment. At present, there are certain in-situ silt solidification technologies and equipment to treat tidal flat silt with relatively high moisture content. The purpose of the above two treatments is to solidify the silt In order to convert it into engineering soil with good engineering properties, so as to realize the effective utilization and resource utilization of sludge; currently, for sludge with high moisture content, it is generally transported through pipelines, and solidification materials are added to the pipeline during the transportation process. Neither a large-scale sludge solidification factory nor large-scale sludge solidification equipment is required. The sludge solidification procedure is simplified and has good continuity and operability. The patent application number is 200610038973.X, but the patented technology Disadvantages: 1. The uniformity cannot be guaranteed, there is no stirring device in the pipeline, and the sufficient mixing of the sludge and the solidified material cannot be achieved only by air pressure; 2. Since the concentration of the sludge slurry in the pipeline changes in real time, the amount of curing agent added is fixed , it is impossible to accurately add curing agent to the sludge slurry with different concentrations, which leads to the difficulty in controlling the quality of the solidified soil; 3. With the flow of the sludge slurry, the flow rate is greatly lost in the pipeline, and there is no pressurization device, resulting in lower processing efficiency. getting lower
