Simple remediation device for heavy metal contaminated soil

Abstract

The invention discloses a simple remediation device for heavy metal contaminated soil. The device comprises a base, and four groups of rollers are arranged at the bottom end of the base. A mounting table is arranged on the inner bottom wall of the base. A fan-shaped groove is formed in the lower part of the mounting table. A feeding hole is upwards formed in the top end of the base. A wedge-shapedblock is arranged at the top end of the base. A solution tank is fixedly mounted at the left end of the base. A heating block is arranged at the bottom of the solution box. A wedge-shaped soil shoveling mechanism is fixedly mounted at the right end of the base. A motor cavity is formed in the mounting table. A centrifugal cavity is formed above the motor cavity. A crushing cavity is formed abovethe centrifugal cavity. Transmission cavities are formed in front of and behind the crushing cavity and the motor cavity. Gear cavities are formed in front of and behind the transmission cavities. Thedevice is simple in structure and simple and convenient to use. Manual soil carrying can be simulated through cooperation of the wedge-shaped soil shoveling mechanism, a torsion spring and the wedge-shaped block. According to an electrodynamic method and the principle of different unit masses for different substance densities, soil is centrifuged through a centrifugal frame to separate out heavymetals, so that a simple remediation effect on the heavy metal contaminated soil is realized, and meanwhile, the defects of large occupied area and high expenditure occupation are overcome.

Description

technical field [0001] The invention relates to the technical field of regeneration of polluted soil, in particular to a simple restoration device for soil polluted by heavy metals. Background technique [0002] In today's life, the remediation of heavy metal soil is one of the most important topics nowadays, and the existing soil remediation technologies such as physical treatment, chemical treatment and electrodynamic treatment all need to move the soil to be treated, and at the same time The soil remediation machinery occupies a large area, severely utilizes the land occupancy rate and funds, and also consumes manpower and material resources. Aiming at how to simply repair the soil contaminated by heavy metals, a simple repair device for heavy metal-contaminated soil designed by the present invention can solve this problem. question. Contents of the invention [0003] technical problem: [0004] In the direction of heavy metal soil remediation, physical treatment, che...
