Description

Technical Field

[0001] The utility model belongs to the technical field of silt treatment, and specifically relates to a silt drying, spreading and turning-over device. Background Art

[0002] Silt is mainly composed of sediment, clay minerals and organic substances at the bottom of rivers, lakes and ponds. It is a modern sediment formed through long-term biochemical action in an environment with slow water flow. It is rich in organic matter, generally dark gray or dark green in color, and sometimes accompanied by an odor.

[0003] In the prior art, a silt recycling and solidifying device with the publication number of CN 220845856 U includes a support frame; a conveying assembly is inclinedly assembled inside the support frame for conveying silt. Through the operation of a conveying belt, the shoveled silt can be conveyed, and it can cooperate to turn over the silt, which can achieve the exhaust effect of the silt. During the turning-over process, a solidifying agent is replenished at the same time, which can make it more convenient to solidify the silt. At the same time, after the silt is conveyed onto a sieve plate, the silt automatically leaks down. The sundries in the silt are sent to a storage hopper along the downhill of the sieve plate, realizing the further screening of the silt, which can improve the solidifying effect of the silt, avoid the influence of various sundries mixing on the solidifying effect, remove the mixed sundries, and is convenient to be directly used for foundation filling or used for farming, greatly saving the construction cost, saving land resources, realizing ecological restoration, resource recycling and sustainable development.

[0004] Currently, when treating silt, it is treated by drying and solidifying. During the drying process, in order to improve the solidifying efficiency, the dried silt is turned over and solidified. During the turning-over process, due to the high-speed operation of the turning-over machine, the silt will be splashed high and unevenly turned over, affecting the subsequent spreading and drying. Therefore, in view of the above problems, a silt drying, spreading and turning-over device is proposed. Content of the Utility Model

During the traction movement of the turning-over mechanism, the bottom end of the limit frame can limit the thickness of the silt, which can better ensure the uniform spreading of the silt.
