Dehydration and curing device for river channel silt

Abstract

The invention discloses a dehydration and curing device for river channel silt. The device comprises a silt treatment and conveying system, a coagulant stirring and conveying system, a pipeline mixer, dehydration filter bags, a water collecting groove, a drainage well and a control system, wherein the silt treatment and conveying system comprises a silt impurity-removing pool, and a silt pumping and conveying device is arranged in the silt impurity-removing pool; the coagulant stirring and conveying system comprises a coagulant storage device, a coagulant conveying device, a coagulant stirring device and a coagulant pumping and conveying device; the pipeline mixer is connected with the multiple dehydration filter bags, each dehydration filter bag is provided with a drainage device in the circumferential and / or in the longitudinal direction, and a height control device is arranged above each dehydration filter bag. According to the dehydration and curing device for the river channel silt, by the utilization of the filtration function of the dehydration filter bags, in combination with the addition of corresponding flocculating agents, power consumption produced by mechanical dehydration can be greatly reduced, the silt discharging speed is high, the silt discharging amount is large, the dehydration and curing device is very suitable for treating a large amount of silt, simple in structure and easy to operate, no much manual operation needs to be carried out in the usage process, and the labor cost is saved.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, in particular to a device for dehydrating and solidifying river sludge. Background technique [0002] At present, there is a large amount of tidal mud on the outside of the enclosure, which not only endangers the marine ecological environment, but also poses safety hazards to the reclamation project. At the same time, the dredged silt in river and waterway dredging projects cannot be effectively solved. Most of the dredged silt is disposed of by discarding landfills or low-lying areas, or setting up storage yards for storage, which not only occupies fishing ponds and cultivated land , and the formed land is very weak and difficult to develop and utilize. Contents of the invention [0003] The object of the present invention is to provide a device for dewatering and solidifying river sludge. It can process a large amount of silt in the river quickly and quickly, and can improve the tr...
