Soil remediation filtration system and soil filtration and separation repair method

Abstract

The invention relates to a soil remediation filtration system and a soil filtration and separation repair method. The system comprises a bottom plate, a box, a rolling mechanism, a screening mechanism, two electromagnetic separation mechanisms and a conveying mechanism, wherein the box is mounted on the bottom plate, the box is of a structure with a top opening, conveying grooves are formed in left and right ends of the lower side of the box, the rolling mechanism, the screening mechanism and the electromagnetic separation mechanisms are sequentially mounted on the box from top to bottom, thetwo electromagnetic separation mechanisms are symmetrically mounted on the box, the conveying mechanism is mounted on the bottom plate and mounted in the conveying roves, polluted soil is crushed by the rolling mechanism and screened by the screening mechanism, large particulate matter is filtered out, the electromagnetic separation mechanism adsorbs heavy metals in the screened soil, and the problems that hardened soil is not easy to crush thoroughly, heavy metals in hardened blocks are not easy to separate, collected metal elements contain a large quantity of soil and impurities and the likeare solved.

Description

technical field [0001] The invention relates to the field of soil remediation equipment, in particular to a soil remediation filter system and a filtering and separation soil remediation method. technical background [0002] With the development of society and economy, people's requirements for the environment are getting higher and higher, and relevant laws and regulations on the remediation of heavy metal-contaminated soil have been issued. Heavy metal-contaminated soil contains a large amount of recyclable metals. It is separated from the soil, and manual extraction is not only time-consuming and labor-intensive, but also low in efficiency. In addition, because heavy metals pose a lot of personal hazards to workers, the current soil restoration methods at home and abroad mainly include physical restoration, chemical restoration and physical restoration. , but the chemical restoration method and the physical restoration method have the disadvantages of high cost, incomplet...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a soil remediation filtration system and a method of filtering and separating soil remediation, which can solve the problem that manual operation and extraction are not only time-consuming and labor-intensive, but also have low efficiency. However, the metal elements are not easy to separate from the soil in the existing physical separation repair, and the efficiency is low, and the collected metal elements contain a large amount of soil and impurities. and other problems, because the soil compaction is not easy to be completely crushed, and the heavy metals in the compaction are not easy to separate out, which increases the difficulty of soil restoration and other problems. It improves the work efficiency and reduces the labor intensity of the staff. At the same time, the secondary rolling and secondary screening are set up, which is conducive to crushing the soil plate agglomerates and separating them from the metal elements. There are few impurities in the collected metal elements, which is beneficial to the later stage. Handling and other advantages
