Screening and dosing reaction device for repairing contaminated soil through chemical oxidation

The invention discloses a screening and dosing reaction device for repairing contaminated soil through chemical oxidation. The device comprises a feeding hopper, a vibration rotating base, a conveyingmechanism, a dosing reaction box, a rotating mace device and a medicament adding mechanism, the conveying mechanism comprises an upper conveying mechanism body and a lower conveying mechanism body, and the medicament adding mechanism comprises a solid medicament adding mechanism body and a liquid medicament adding mechanism body. According to the invention, the screening, dosing, mixing and stirring devices of the contaminated soil are effectively combined; by arranging a good gas passage, the risk of explosion caused by concentrated generation of a large amount of gas in the reaction processis reduced, and remediation agents of different types and different concentrations can be adopted to quickly remediate the contaminated soil according to different contaminated soil types. The deviceis suitable for treatment
