Abstract

The invention discloses a piston squeeze-type water-sand separation apparatus in the technical field of comprehensive utilization of dredged soil, and aims to solve the technical problems in the priorart that most of the dredged soil is treated in a throwing-out manner, a comprehensive utilization level is not high, and adverse effects are caused on the marine environment and water ecology. The apparatus comprises a shell and a sand inlet cover, the shell is provided with a sand outlet, a sand inlet adapted to the sand inlet cover, and a filter screen for discharging water in the sand, the inner wall of the shell is connected with a piston in a slide manner, the piston is connected with a power output end of a first driving source in a transmission manner, the first driving source drivesthe piston to slide in the shell, and the inside of the shell is also provided with a heating component for drying the sand and a conveying component for conveying the sand to the sand outlet.

Description

technical field [0001] The invention relates to a piston extrusion type water-sand separation device, which belongs to the technical field of comprehensive utilization of dredged soil. Background technique [0002] For a long time, dredged soil has been considered as waste, and a large amount of dredged soil has been disposed of by throwing away, which has caused certain impacts on the marine environment and water ecology. On the basis of a large number of scientific researches and engineering practices, the view that "dredged soil is a usable resource" has been accepted by all walks of life, and the call for making full use of dredged soil is also growing louder. Reasonable disposal of dredged soil can not only reduce the impact on the environment, but also increase a large amount of land resources, provide industrial, agricultural and living land, contribute to the sustainable development of the national economy, and realize the harmonious development of man and nature. ...
