A screening device for soil restoration

Abstract

The invention discloses a screening device for soil remediation, which comprises a screening box, the upper end of the screening box starts to have a feeding trough, the inner wall of the feeding trough is offset by an upper cover, and the inner wall of the screening box A partition is fixed, and the upper end of the partition is provided with a plurality of division grooves, the inner wall of each division groove runs through and connects the partition tube, and the circumferential side wall of each partition tube is fixed with a plurality of Scraper, the outer wall of the screening box is fixed with a bearing plate, the upper end of the bearing plate is provided with a power mechanism, and the side wall of the screening box is provided with an air outlet slot. The advantage is that the rotating tube is driven by the motor to rotate, so that the rotating tube drives the stirring plate on it to rotate, so that the stirring plate can effectively stir the soil on the top of the partition, so that the soil is stirred and pulverized, which is convenient for subsequent screening. The rotation of the pipes is opposite, and the soil between the two rotating pipes is subjected to greater shear force, so that the mixing and crushing effect of the soil is strengthened.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a screening device for soil restoration. Background technique [0002] Soil remediation is a technical measure to restore contaminated soil to normal functions; in the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three types: physical, chemical and biological. method. [0003] Most of the soil remediation process needs to screen the soil to clean out the sand and debris mixed in the soil, which is convenient for repairing the soil by repairing the liquid, and at the same time avoiding damage to the machine caused by larger particles of sand and gravel. Most of the existing screening methods realize the separation of soil and debris by shaking the screen, but this method can easily lead to blockage of the screen, and frequent cle...
