Chemical leaching device for soil remediation

Abstract

The invention discloses a chemical leaching device for soil remediation. The chemical leaching device for the soil remediation comprises a box body, wherein a base plate is fixed to the outer wall ofthe bottom of the box body through bolts; a filter box is fixed to one side of the outer wall of the top of the base plate through bolts; a motor is fixed to the central position of the outer wall ofthe top of the box body through bolts; a transmission shaft is welded to the bottom end of an output shaft of the motor after penetrating through the inner wall of the top of the box body; a fixing ring is welded to the outer wall of one side of the transmission shaft; stirring rods distributed annularly at equal distances are welded to the outer wall of one side of the fixing ring; and connectingrods distributed annularly at equal distances are welded to the outer wall of one side of the transmission shaft. According to the chemical leaching device for the soil remediation, the generated heat can be uniformly and rapidly conducted into the soil, the volatilization efficiency of organic matters in the soil is improved, raw materials can be lifted and scattered upwards, the contact area between the organic matters in the raw materials and air is promoted, volatilization is promoted, and the reaction completeness with a chemical solution can be promoted.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a chemical washing device for soil restoration. Background technique [0002] As the foundation of human survival, soil is an indispensable material wealth in our life. The utilization and protection of soil resources are closely related to the survival and development of human society. With the continuous acceleration of the industrialization process, the unreasonable exploitation of mineral resources and their smelting discharge, the long-term sewage irrigation and sludge application to the soil, the atmospheric subsidence caused by human activities, and the application of chemical fertilizers and pesticides have caused serious soil pollution. Pollution. Soil pollution can directly pollute crops and reduce production, leading to direct economic losses. At the same time, harmful substances can accumulate in crops and enter the human body through the food chain, causing...
