Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, and in particular to a hydrated sludge dry-wet separation device based on municipal street sweeping soil. Background Art

[0002] At present, in order to improve the quality of sanitation operations, road sweeping operations have changed from mainly dry sweeping to mainly washing and sweeping. While ensuring high-quality operations, it has also brought new problems, namely, the water content of street sweeping soil is too high. The street sweeping soil collected by road washing and sweeping operations will contain a lot of water, and a large amount of sewage will be mixed in again during the unloading and flushing process, resulting in the high water content of the dry component and failing to meet the transfer station's acceptance requirements. At the same time, street sweeping soil with too high a water content is also prone to cause mesh sticking in the sorting equipment, and is prone to secondary pollution risks during the transfer to the sorting station, thereby affecting the life of the transfer vehicle.

[0003] In the prior art, the processing operation structure for the street sweeping soil with too high water content is usually only a single drainage without dehydration. The moisture content of the street sweeping soil after treatment in this mode is still too high, and the materials transported to the transfer station have leakage problems during the transportation process and cannot meet the acceptance standards of the transfer station; or after the operation is completed, the collected street sweeping soil is directly dumped at the soil unloading point or garbage bin, and then the water is controlled by the shade drying method before collection and transportation. This mode has the disadvantages of garbage exposure, serious on-site environmental pollution, and overall time consumption. It occupies a large site area, which seriously affects the collection and transportation efficiency of the street sweeping soil. Summary of the invention
