Abstract

The present invention relates to the field of soil remediation, in particular to a soil screening device for soil remediation, comprising a crushing cylinder, a motor, a stirring block, an elastic grinding piece, a screening assembly, and a transmission shaft; the transmission shaft is vertically arranged in the crushing cylinder, and It rotates under the drive of the motor; the elastic grinding assembly includes a fixed outer ring, a fixed inner ring, and a plurality of elastic strips. The upper end is connected to the fixed outer ring, and the lower end is connected to the fixed inner ring, and the projection of each elastic strip in the horizontal plane is spiral; When the shaft rotates, it interacts with the elastic bar to crush the blocky soil, so that the elastic bar is stretched under the extrusion of the blocky soil, and then the fixed inner ring rotates, and recovers part or all of the contraction when the pressure decreases or disappears; sieving The module receives crushed soil lumps for filtration.

Description

technical field [0001] The invention relates to the field of soil restoration, in particular to a soil screening device for soil restoration. Background technique [0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil, reducing its concentration to an acceptable level, or converting toxic and harmful pollutants into harmless substances. In the existing physical repair, there is a separation repair method, which screens out heavy metal pollutants in the soil through a screen, but the soil is prone to moisture and agglomeration, and the blocky soil will block the screen mesh during screening. The soil is pre-broken, but the crushing process will lead to slow feeding speed and affect the screening efficiency. Therefore, there is a need for a soil screening device that improves the feeding speed of the crushing process. Contents of the invention [0003] The invention provides...
