Abstract

The invention relates to the field of soil remediation, in particular to a soil screening device for soil remediation. The device comprises a crushing cylinder, a motor, a stirring block, an elastic grinding piece, a screening and filtering assembly and a transmission shaft. The transmission shaft is vertically arranged in the crushing cylinder and is driven by the motor to rotate; the elastic grinding assembly comprises a fixed outer ring, a fixed inner ring and a plurality of elastic strips, the fixed outer ring is fixed to the crushing cylinder, and the fixed inner ring is located below the fixed outer ring and smaller than the fixed outer ring; the upper end of each elastic strip is connected with the fixed outer ring, the lower end of each elastic strip is connected with the fixed inner ring, and the projection of each elastic strip in the horizontal plane is spiral; the stirring block is installed on the transmission shaft and located in an annular space defined by the elastic strips, the stirring block interacts with the elastic strips when rotating along with the transmission shaft to crush blocky soil, the elastic strips are made to extend under extrusion of the blocky soil, then the fixed inner ring is made to rotate, and partial or complete contraction is recovered when the pressure is reduced or disappears; and the screening and filtering assembly is used for receiving and filtering the crushed blocky soil.

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...
