Rapid slurry dehydration device and dehydration method thereof

Abstract

The invention discloses a rapid slurry dehydration device and a dehydration method thereof. The device comprises a hollow outer cylinder; a plurality of water seepage holes are uniformly formed in the side wall of the hollow outer cylinder; geotechnical cloth is attached to the inner side wall of the hollow outer cylinder; a bottom plate is closed and fixed at an opening in one end of the hollow outer cylinder; one end of a cross plate is fixedly connected with the bottom plate in an inserted way; a partition plate group comprises at least one set of partition plates; the number of the isolation plates in one set is four, each isolation plate is a long-strip-shaped rectangular plate, one end of each isolation plate is connected with the bottom plate in an inserted mode, the two side edges of each isolation plate are attached to the two adjacent side walls of the cross plate, and a three-dimensional structure with the rectangular cross section is defined by the four isolation plates; and a high-performance water-absorbent resin bag is packed in a gap between the inner wall of the hollow outer cylinder and the outer side wall of the outermost set of isolation plates. The invention provides a rapid dehydration device for high-water-content slurry and a dehydration method of the rapid dehydration device, aiming at the problems of low efficiency, high energy consumption, easiness in abrasion of equipment and incapability of achieving economization and sustainability of a slurry dehydration method at the present stage.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, and more specifically relates to a rapid mud dehydration device and a dehydration method thereof, which are used for rapidly treating mud with a high water content to facilitate further construction operations. Background technique [0002] With the rapid development of urbanization and modernization, many construction sites and mines in our country will produce a large amount of mud. These muds often have high water content, and direct discharge will cause pollution to nearby watersheds. It is not easy to transport without treatment, so It is necessary to carry out rapid dehydration treatment on such mud. [0003] In order to solve the above problems, there are two main methods of mud dehydration at this stage: natural drying method and mechanical dehydration method. Natural drying takes up a large area, poor sanitation, and low efficiency. Mechanical dehydration consumes a lo...

AI Technical Summary

Problems solved by technology

Natural drying takes up a large area, poor sanitary conditions and low efficiency

Mechanical dehydration consumes a lot of energy, the equipment is expensive, and the sludge contains gravel, which is easy to wear and tear, and cannot meet the basic requirements of economical and sustainable development. Therefore, the above methods cannot effectively solve practical engineering problems.
