TECHNICAL FIELD

[0001] The present application relates to the technical field of soil remediation, in particular to a high-efficiency soil remediation device with overturning function. BACKGROUND

[0002] Soil is an important natural environment for human survival. With the rapid development of industry, soil has become the final destination of various pollutants, and the large accumulation of pollutants has become one of the main environmental problems. Volatile organic compounds (VOCs) or semi-volatile organic compounds (SVOCs) pollute the soil after entering the soil, and cause secondary pollution to surface water and groundwater. In the current environment of vigorously protecting the ecological environment in China, soil pollution is a problem that needs to be improved urgently.

[0003] At present, methods such as landfill, incineration, biological treatment and thermal desorption are usually used to remediate VOCs and SVOCs contaminated soil. Landfill and incineration treatment methods have short treatment period, simple method, but high cost, and may cause secondary pollution; biological treatment method has small investment, low operation cost, simple operation, small environmental disturbance, but long remediation period; thermal desorption is one of the mature and reliable technologies internationally recognized for treating VOCs and SVOCs contaminated soil, and is widely used in VOCs and SVOCs contaminated site remediation; thermal desorption technology has good adaptability to different types and concentrations of organic pollutants, and has fast remediation speed and short cycle.

[0004] The existing soil organic matter remediation equipment has poor airtightness in the heating chamber, causing a large amount of heat loss, and the evaporation process is easy to evaporate insufficiently, which requires more resources for heating, resulting in a large amount of heat loss and energy waste, leading to high soil remediation cost and low efficiency, which is not conducive to large-scale promotion. SUMMARY

[0005] The present application aims to provide a high-efficiency soil remediation device with overturning function, which has simple structure and convenient operation, and can solve the problems in the prior art by using overturning to evaporate soil in multiple chambers and using the self-weight of the soil to make the two groups of track devices cooperate to extend the evaporation time.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

A heating chamber is located above the base plate and on one side of the mixing chamber, connected to the mixing chamber via an air pipe. The mixing chamber is connected to the filtering chamber via a connecting pipe. Symmetrical supports are provided on the top of the base plate and on both sides of the heating chamber. A heating blower is mounted on one side of the support.

Two partitions are installed inside the heating chamber, and each partition is equipped with a track device. The surface of the track device is equipped with a plate, and the plates on the adjacent sides of the track device mesh with each other. The top and bottom of the heating chamber are respectively equipped with a feeding chamber and a discharging chamber. The feeding chamber and the discharging chamber are respectively equipped with a first motor, a second motor, a first baffle, and a second baffle. The first motor is controlled and connected to the second baffle, and the second motor is controlled and connected to the first baffle. A hydraulic cylinder is installed at the top of the bottom plate and on one side of the heating chamber.
