Self-running interlayer material conveying device and drying method of contaminated soil

Abstract

The invention relates to a self-running interlayer material conveying device and a drying method of contaminated soil in the technical field of contaminated soil treatment equipment. The conveying device comprises a supporting device, and inner cylinder rotatably and vertically arranged on the supporting device, wherein a first screw blade is fixedly arranged in the inner cylinder; a second screw blade is fixedly arranged on the outer wall of the inner cylinder; an outer cylinder concentric to the inner cylinder is arranged on the periphery of the second screw blade; a material enters from the upper part of the inner cylinder, drops along the first screw blade to drive the inner cylinder to rotate, and directly or indirectly drives the second screw blade to rotate through rotated power of the first screw blade. The self-running interlayer material conveying device has the beneficial effects that according to the conveying device adopting the structure, the material drops by utilizing the self-gravity of the material to drive the first screw blade to rotate so as to enable the inner cylinder to rotate, and drives the second screw blade to rotate at the same time, so that an inner layer and an interlayer of the device are used for conveying materials at the same time, external power equipment has no need to be used, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of contaminated soil treatment equipment, in particular to a self-operating interlayer material conveying device and a method for drying contaminated soil. Background technique [0002] Thermal desorption technology is an important contaminated soil remediation technology, which can quickly remediate the soil that has been polluted by organic matter, and can achieve a good remediation effect. This technology uses heating to heat the soil polluted by organic matter to above the boiling point of organic pollutants, so that the organic matter adsorbed in the soil volatilizes, desorbs into the gas phase, and then separates it into a gaseous state to achieve separation from the soil and achieve purification. Soil purpose. After desorption, the exhaust gas containing organic pollutants is harmlessly disposed of by other means. Thermal desorption technology can effectively remove various types of volatile organic...
