River and lake waterway desilting and screening device

Abstract

The invention relates to the technical field of ecological river and lake waterway desilting, in particular to a river and lake waterway desilting and screening device. The river and lake waterway desilting and screening device is characterized in that the river and lake waterway desilting and screening device comprises a rotating roller which is obliquely arranged and a driving mechanism used fordriving the rotating roller to rotate, a cylinder of which the two ends are open is adopted as the rotating roller, the inner wall of the cylinder is provided with guiding sheets used for stirring silt and guiding the silt to the oblique horizontal low direction of the cylinder, and the cylinder wall of the cylinder is provided with screening holes used for screening coarse and fine silt. According to the river and lake waterway desilting and screening device, the structure is simple and reasonable, and the silt cleaned in a waterway can be conveniently, efficiently and uniformly screened.

Description

technical field [0001] The invention relates to the technical field of ecological dredging of river and lake waterways, in particular to a river and lake waterway dredging and screening device for sorting and screening the silt and sand of waterways. Background technique [0002] At present, the sieving work of the existing water channel silt is realized by the filter screen plate placed at an angle. The sediment is directly discharged from the top of the filter screen plate and filtered through the filter screen plate. Since the filter screen plate is passive In the working state, the silt and sand are filtered and sieved with the help of sieve holes and inclined gravity, but the processing efficiency of this method is not high, especially for the factors of silt and sand with many impurities and complex components or high viscosity, the sieving efficiency is relatively low. It is difficult to improve, and the impurities after screening and filtering are too much and very u...

It is difficult to improve, and there are too many and uneven impurities after screening and filtration, and the filter material under the sieve plate is also difficult to clean and transport
