Problems solved by technology

[0004] The object of the present invention is to provide a kind of contaminated soil remediation equipment based on ex-situ chemical leaching to solve the above-mentioned background technology. In order to ensure the sufficiency of soil remediation, in the purification process of a single operation of the equipment, the specified amount of soil will be To carry out the corresponding spray repair, before carrying out subsequent batches of soil repair, it is necessary to clean up the corresponding containing structure in the equipment to avoid the problem of lower efficiency of subsequent soil repair due to incomplete cleaning, and because the soil is being After spraying the solution, it is in a relatively diluted state. Although the soil discharged after remediation has special equipment for secondary treatment, it is very troublesome to clean up the remaining diluted soil, which greatly reduces the efficiency of soil remediation.

Abstract

The contaminated soil remediation equipment based on ex-situ chemical leaching comprises a base and a containing box, a first transverse cylinder rotationally installed in the base is rotationally installed at the right end of a rotating shaft in a one-way mode through a one-way bearing, and the rotating shaft located in the base is connected with a motor; and a second transverse cylinder is also rotationally mounted on the rotating shaft in a one-way manner. According to the contaminated soil remediation equipment based on ex-situ chemical leaching, the containing box is designed into an upper containing space and a lower containing space, and the other used space can be synchronously cleaned while soil in one space is sprayed in a self-rotation mode; and meanwhile, switching use of different containing boxes and cleaning of the containing boxes can be achieved through the same power source, space division is achieved through partition plates, and meanwhile separation of metal impurities and improvement of the spraying effect can be achieved through operation of internal electromagnetic plates.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a contaminated soil remediation device based on ex-situ chemical leaching. Background technique [0002] The ectopic chemical leaching method refers to digging out the contaminated soil from the ground, and after simple screening and removal of impurities, it is transported to the corresponding spraying equipment, and the chemical solution and the soil are sprayed by spraying. The heavy metals and oil pollution components in the soil are in contact with the soil, and the soil is backfilled after the purification is completed. Therefore, the existing similar repair equipment based on the ex-situ chemical leaching method has the following problems in actual use: [0003] In order to ensure the adequacy of soil remediation, in the purification process of a single operation of the equipment, the specified amount of soil will be sprayed and repaired accordingly. to avoid the...
