Uniform stirring device for contaminated soil remediation

Abstract

The invention discloses a uniform stirring device for contaminated soil remediation. The uniform stirring device comprises a first box and a second box, wherein the second box is arranged at the left end of the first box, a second motor is arranged at the left end of the second box, a first motor is arranged at the right end of the first box, a rotary shaft connected with the second motor is arranged on the inner side of the second box, a rotary drum connected with the first motor is arranged on the inner side of the first box, a plurality of stirring blades are arranged uniformly on the outer side of the rotary drum, helical blades are arranged on the rotary shaft on the inner side of the second box, and a plurality of smashing cutters are arranged uniformly in a staggered manner on the rotary shaft on the inner side of the rotary drum. The uniform stirring device is compact and stable in structure, can be used for rapid and uniform stirring for contaminated soil remediation, and improves the contaminated soil remediation effect.

Description

technical field [0001] The invention relates to a stirring device, in particular to a uniform stirring device for treating polluted soil. Background technique [0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, etc. Organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, 3,4-benzopyrene, and harmful microorganisms brought by urban sewage, sludge, and manure. When there are too many harmful substances in the soil and exceed the self-purification capacity of the soil, the composition, structure and function of the soil will change, the microbial activities will be inhibited, and the harmful substances or their decomposition products will gradually accumulate in the soil through "soil→pla...

AI Technical Summary

Problems solved by technology

[0003] Nowadays, soil pollution is getting more and more attention from people, and the control of soil pollution is also in progress. In the process of soil pollution control, it is necessary to enter the treatment agent to adjust the soil, but the existing soil mixing device has poor working stability. , the working mode is single, and the contaminated soil cannot be stirred quickly and uniformly, resulting in uneven distribution of the agent and affecting the effect of contaminated soil treatment
