Abstract

The invention belongs to the technical field of buildings, in particular to an extraction device for remediation of heavy metal contaminated soil. The problems that the extraction device for remediation of the heavy metal contaminated soil is single in structure and holes are liable to block are solved, and according to the following scheme, the extraction device comprises a carriage; the two endsof the bottom of the carriage are connected with two wheel brackets by bolts, and the inner walls of the both sides of the four wheel brackets are sleeved with two wheel rotating shafts through bearings; the two ends of the peripheral walls of the two wheel rotating shafts are connected with wheels by bolts. In the extraction device, by using a turnover plate, the peripheral wall of a feeding conveyor belt is provided with a turnover rubber block; when the turnover rubber block runs to the bottom of the turnover plate, soil can be turned over with the turnover plate due to the blockage effectof the turnover rubber lock, so that the back side of the soil is sprayed subsequently; and the heavy metal contaminated soil can be sprayed with chelating agents overall effectively.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to an extraction device for remediation of heavy metal polluted soil. Background technique [0002] The development of the chemical industry has kept my country's GDP growing continuously, which represents the development of the country. The faster the industry develops, the stronger the country's manufacturing capacity is, and the faster the country develops. But on the contrary, the rapid development of the chemical industry , making the environment more and more polluted. After the site of the chemical industry is relocated, the soil contains a large amount of heavy metal ions, which endanger people's normal life. Only by removing these heavy metal ions can the land be used normally. [0003] In the process of heavy metal treatment, due to the pollution of heavy metals, and the treatment of heavy metals is very cumbersome, after a scientific search, the chelating agent pr...
