Pretreatment equipment for high-water-content clayed soil

Abstract

The invention relates to pretreatment equipment for high-water-content cohesive soil, which comprises a bottom supporting steel plate, and a feeding device and a drying device which are communicated with each other are arranged on the bottom supporting steel plate; the feeding bin comprises a feeding bin shell, wherein a feeding port is formed in the feeding bin shell, a feeding scraper power railis arranged in the feeding bin shell and driven by a feeding scraper power motor, and a feeding scraper is arranged at the end, close to the feeding port, of the feeding scraper power rail. A reciprocating type ruler-shaped soil cutter and a telescopic bulldozing plate are arranged at the front end of the portion, communicated with the drying device, of the feeding device, and the reciprocating type ruler-shaped soil cutter is located below the telescopic bulldozing plate. According to the invention, the moisture in soil is squeezed out through the hydraulic system, so that the heating area is increased, polluted soil can be rapidly and thoroughly dried, and the problems that when existing equipment is used for treating high-moisture-content clayed soil, efficiency is low, and energy consumption is high are solved, and the treatment efficiency for the high-moisture-content clayed soil is greatly improved.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to equipment for pretreatment of cohesive soil with high water content. Background technique [0002] Soil is the basis for human survival, the premise of ensuring food security, and the foundation of agricultural production. However, with the sustained and rapid development of our country for many years, the soil environment has begun to deteriorate. Especially in recent years, the situation of soil pollution in my country has been very serious. The number of soil pollutants exceeding the standard is 19.4%, and the proportion of heavy metal and other inorganic pollution is as high as 82.8%, which directly caused economic losses of 20 billion yuan to our country. The problem of soil pollution has become a major issue restricting the development of my country's agriculture, affecting ecological balance and food safety. [0003] Soil remediation technology is divided into i...

Problems solved by technology

[0010] The purpose of the present invention is to propose a pretreatment equipment for highly efficient treatment of cohesive soil with high water content. The equipment squeezes out the soil moisture and increases the heating area through the hydraulic system, so that the contaminated soil can be dried quickly and thoroughly, which solves the problem of existing equipment. The problem of low efficiency and high energy consumption in high moisture content cohesive soil greatly improves the treatment efficiency for high moisture content cohesive soil
