Problems solved by technology

[0003] my country's heavy metal-contaminated soil remediation equipment design level and manufacturing capacity have been greatly improved, but compared with developed countries, it is still lagging behind, mainly because the equipment occupies a large area, its mobility is unstable, and its flexibility is poor. The leakage is serious, causing secondary pollution to the environment; the mixing effect is not ideal, the structure of the tank is too complicated, and maintenance is difficult, resulting in low treatment efficiency

Abstract

The invention discloses heavy metal contaminated soil treatment agent stirring equipment and an operating method thereof. The equipment is composed of a soil feeding hole, a compound admixture adding hole, a lime feeding hole, a stirring chamber, a scale type pneumatic gate valve discharging hole, a moving roller, an outer frame, a power motor and a control system, wherein the soil feeding hole is formed in one side of the stirring chamber; the lime feeding hole is positioned in the other side of the stirring chamber; the compound admixture adding hole is formed between the soil feeding hole and the lime feeding hole; the scale type pneumatic gate valve discharging hole is of a hopper structure; the outer frame is fixedly welded at the periphery of the stirring chamber; the moving roller is fixedly welded with the bottom of the outer frame; and the power motor is fixedly mounted on the side face of the stirring chamber. According to the heavy metal contaminated soil treatment agent stirring equipment disclosed by the invention, the addition amount of compound admixtures can be monitored in real time by the device, and a high-quality treatment effect is achieved; and a pressure weight sensor is arranged at the discharging hole, so that the mixed soil treatment weight can be displayed in real time, and a production report is formed.

Description

technical field [0001] The invention belongs to the application field of soil restoration construction equipment, and in particular relates to a heavy metal polluted soil treatment chemical mixing equipment and a working method thereof. Background technique [0002] The research on heavy metal-contaminated soil remediation equipment first started in Germany. In 1907, Germany began to study heavy metal-contaminated soil remediation equipment and obtained patent rights. Since then, in 1913, the prototype of heavy metal-contaminated soil remediation equipment manufactured in the United States has also obtained a patent. In 1930, Germany manufactured a vertical single-cylinder ball valve piston pump. This pump was driven by a crank and a rocker. The Kuyman-type heavy metal-contaminated soil remediation equipment with a horizontal cylinder has successfully solved the problem of the construction principle of the heavy metal-contaminated soil remediation equipment, and greatly imp...
