Problems solved by technology

[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 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

Embodiment Construction

[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] Such as Figure 1-2 As shown, a dredging and screening device for rivers and lakes, the main body includes a rotating drum 1 arranged obliquely and a driving mechanism 4 for driving the rotating drum 1 to rotate. The rotating drum 1 is a cylinder 21 with openings at both ends. The inner wall of the cylinder 21 is provided with a guide vane 2 that stirs the silt and sand and guides the silt and sand to the direction of the horizontal low point where the cylinder 21 is inclined. The holes 12 include fine sand screening holes 13 arranged on the barrel wall at the front end of the cyli...

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...
