Soil remediation device

Abstract

The invention discloses a soil remediation device. The soil remediation device comprises a side plate, a fixing frame and walking wheels, wherein a shovel plate is rotationally installed at the frontend of the side plate, a soil discharging guide plate is fixed to the rear end of the side plate, and a conveying belt is arranged between the shovel plate and the soil discharging guide plate; a chemical injection mechanism is arranged below the conveying belt; a support is fixed above the side plate; a chemical storage box is installed on the support; a chemical conveying pipe is arranged between and communicates with the chemical storage box and the chemical injection mechanism; and a pressure pump is installed on the chemical storage box. The walking wheels walk to drive the shovel plate to move forwards, so soil skin is shoveled up, is conveyed to the soil discharging guide plate at the rear end through the conveying belt and is then discharged; after a soil surface layer is shoveledup, a chemical spraying head on a roller drills into a deep position of soil, and remediation chemical liquid is injected; then the soil surface layer is covered again; and thus, continuous operationof soil shoveling, chemical injection and soil covering is achieved, and treatment efficiency is high.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to a soil restoration device. Background technique [0002] Soil is an important part of the natural environment and the material basis for human survival. In recent years, with the rapid development of industry and agriculture, the pollution caused has become increasingly serious. Prevention and control of soil pollution and protection of limited soil resources have become prominent global issues. The remediation technologies of contaminated soil mainly include physical remediation methods, chemical leaching, and phytoremediation. [0003] In the remediation of contaminated soil, the existing remediation devices generally inject the remediation agent directly into the soil layer from the soil surface, which cannot ensure that the remediation agent completely penetrates into the depth of the soil layer, resulting in insufficient fusion of the internal soil and the remediati...
