Horizontal double-shaft reverse differential efficient stirring device for soil remediation

Abstract

The invention relates to a horizontal double-shaft reverse differential efficient stirring device for soil remediation. The device comprises an outer shell module, driving modules, stirring modules, afeeding module and a discharging module. The stirring modules and the driving modules are connected through chains, the stirring modules and the outer shell module are connected through bearings, andthe number of the driving modules and the number of the stirring modules are both two; the outer shell module comprises a stirring bin shell and driving bin shells, and the stirring bin shell and thedriving bin shells are separated through steel plates. According to the invention, the horizontal double-shaft reverse differential efficient stirring device for soil remediation inherits stirring capacity of the horizontal double-shaft stirring equipment, and on the basis of a double-shaft stirrer, a group of reverse stirring blades are added behind each group of forward propelling stirring blades, so that the stirring capacity of the horizontal double-shaft stirring equipment is improved, and the stirring capacity and stirring efficiency of the equipment are improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a horizontal double-shaft reverse differential speed high-efficiency stirring device for soil remediation. Background technique [0002] Ex-situ chemical oxidation / reduction technology is to add oxidant or reducing agent to polluted soil, and through oxidation or reduction, the pollutants in the soil can be transformed into non-toxic or relatively less toxic substances. Solidification / stabilization soil remediation technology fixes harmful pollutants in the soil by adding solidification / stabilization agents to the soil by physical or chemical methods, or converts pollutants into chemically inactive forms, preventing them from being released in the environment. It is a remediation technology that reduces the degree of toxicity of pollutants through processes such as migration and diffusion. [0003] The above remediation technologies all need to mix the agent with the so...

AI Technical Summary

Problems solved by technology

[0004] At present, the mixing equipment used for soil remediation mainly includes horizontal double-shaft mixing equipment; Allu-type crushing and screening equipment; 2 to 3 sets of horizontal shaft crushing knives Crushing and mixing equipment composed of , hammer; horizontal axis mixing equipment composed of multiple sets of horizontal axis mixers, etc. However, the above equipment for mixing soil and chemicals often has uneven mixing. In addition, the Allu type crushing and screening equipment belongs to open operation, mixing The process is easy to generate dust, and it also has the potential to cause secondary pollution to the surrounding environment

[0005]The existing soil remediation equipment has low repair efficiency and poor mixing effect. will have a great impact on the final results of soil remediation

The existing mixing equipment used for soil remediation has poor continuous mixing ability

For cohesive soil with high moisture content, the existing soil restoration mixing equipment has poor mixing capacity, and it is easy to cause blockage of the mixing chamber

The mixing equipment used in existing soil remediation equipment usually adopts an open design, and the mixing process is prone to generate dust, which may also cause secondary pollution to the surrounding environment.

[0006]Therefore, there are still limitations and deficiencies in the current equipment, and the degree of mixing uniformity between the agent and the soil has increasingly become an important factor restricting the effect of soil remediation
