TECHNICAL FIELD

[0001] The present application relates to the technical field of trenching residual mud treatment devices, in particular to a fine sorting device for trenching residual mud. BACKGROUND

[0002] The trenching residual mud sorting system is a combination of a series of mechanical equipment and process flow specially used for processing the residual mud generated by the dredging of urban drainage pipelines and effectively sorting, classifying and preliminarily processing the residual mud. Its purpose is to separate different components (such as sand, slag, organic matter, plastic fragments, metal debris, etc.) in the trenching residual mud according to factors such as properties, sizes and weights, so as to be subsequently used for resource utilization, harmless disposal or standard discharge. In the tail process of the current trenching residual mud sorting system, the fine sand in the water is not fully sorted, and in the cyclone sand separation process, the centrifugal force generated by the collision of the sand body is insufficient for the fine sand with a particle size too large, which is then affected by the water flow and enters the sewage system with the water body, which will cause accumulation and blockage of the water pipeline over a long period of time, adversely affecting the operation of the system.
