Abstract
Description
Technical Field
[0001] This utility model belongs to the field of soil remediation heating, and specifically relates to a soil remediation thermal descaling additional heating device. Background Technology
[0002] Thermal desorption treatment can effectively remediate soil pollution by heating pollutants to volatilize or separate them, restoring soil function and thus achieving the goal of soil remediation. Soil thermal desorption mainly uses heating to convert organic pollutants in the soil from a solid state to a gaseous state. During the heating process, the molecular motion of pollutants intensifies after being heated, and they gradually detach from the soil particles. In this way, organic pollutants are effectively removed, and the soil can restore its original function and value. However, existing heating devices cannot heat the soil interior uniformly. Due to unstable temperature, organic matter cannot be decomposed, which reduces the efficiency of soil pollutant separation.
[0003] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, they have been modified and improved. At the same time, in the spirit and concept of seeking the best, with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created to provide a soil remediation thermal descaling additional heating device to solve the problem.

The support frame 1 has a mixing box 5 installed on its upper part. The mixing box 5 can crush large pieces of soil. A first drive motor 6 is provided on one side of the mixing box 5. The first drive motor 6 can drive the soil crushing mechanism 7 to rotate. The soil crushing mechanism 7 is installed inside the mixing box 5. The soil crushing mechanism 7 can crush the soil quickly. A partition 9 is installed at the lower end of the mixing box 5. The partition 9 can make the soil evenly distributed on the metal conveyor belt 12. The heating box 2 has a heating diversion block 10 and a heating air outlet 11 on the upper side near the metal conveyor belt 12. The heating diversion block 10 can make the soil separate from each other.
[0023] Furthermore, the soil pulverizing mechanism 7 is connected to the mixing tank 5 and the first drive motor 6 via a connecting shaft, and the soil pulverizing mechanism 7 can be rotated inside the mixing tank 5 by means of the first drive motor 6.
[0024] Furthermore, the soil pulverizing mechanism 7 includes a fixed sleeve and a pulverizing rod, the length of which is less than the width of the mixing box 5, so that the pulverizing rod can rotate inside the mixing box 5.
[0025] Furthermore, the metal conveyor belt 12 is made of stainless steel and is rotatably connected to the drive shaft 4, so that the metal conveyor belt 12 can rotate inside the heating box 2, thereby moving the soil.
[0026] Furthermore, the heating diversion blocks 10 are distributed in an alternating pattern, and there is a gap between the heating diversion blocks 10 and the metal conveyor belt 12.
