A rapid processing machine and processing method for metal-containing soil

Abstract

The invention belongs to the technical field of soil processing, and particularly relates to a metal-bearing soil rapid processing machine and a processing method. The machine comprises supporting legs and a shell. The top of the shell is provided with connecting rods and an installing plate. Power mechanisms are installed on the installing plate. A grinding block is installed on the inner side wall of the shell. First crushing bars are fixedly installed on rotating shafts horizontally. A supporting column is vertically fixed to the lower surface of the installing plate. Second crushing bars are fixedly installed on the outer surface of the supporting column horizontally. Through grooves run through the grinding block. First canvas cylinders are fixedly attached to the inner side walls ofthe through grooves. Second canvas cylinders are fixedly attached to the outer surfaces of the rotating shafts. A second guide plate is arranged on the inner side wall of the shell. A filter screen isconnected with the edge of the second guide plate. A discharge port is formed in a bottom plate of the shell. Striking mechanisms are arranged below the second guide plate and the filter screen. Whenmetal-bearing soil is processed through the metal-bearing soil rapid processing machine, iron wires and iron scraps can be completely separated from the soil, the ground soil is not prone to caking,small metal particles and small soil particles can be completely separated, and the leaching effect is improved.

Description

technical field [0001] The invention belongs to the technical field of soil treatment, and in particular relates to a rapid treatment machine and a treatment method for metal-containing soil. Background technique [0002] Soil pollution occurs through various means such as waste dumping, leakage of hazardous substances, use of pesticides and fertilizers, and incineration. Soil pollution not only causes various problems such as the disorder of the soil ecosystem, crop pollution, and the absorption of pollutants by the human body, but also acts as a source of secondary pollution to surface water, groundwater, and air. Compared with air pollution and water pollution, soil pollution is long-term, and recovery also takes a lot of time and cost. Among them, metal-contaminated soil will have a great impact on human health, so it is urgent to study the purification and treatment methods of metal-contaminated soil.

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a metal-containing soil rapid processing machine and processing method, aiming to solve the following problems existing in the processing of metal-containing soil by using the metal-contaminated soil restoration integrated machine in the prior art: (1) the iron wire and the The iron filings are separated from the soil, and the degree of repair is low, which limits the scope of application of the repaired soil; (2) The soil is not sufficiently ground, causing the soil to stick into blocks, and some small metal particles are wrapped in the soil, causing leaching The agent cannot fully contact the small metal particles in the soil, and the repair effect is poor
