Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of contaminated soil treatment and stirring, and more specifically to a uniform stirring device for contaminated soil treatment. Background Art
[0002] Contaminated soil refers to soil that contains chemicals, heavy metals, and radioactive substances that are harmful to the environment and organisms, causing it to lose its original functions and ecosystem balance, posing a threat to human health and the environment. Contaminated soil can have significant impacts on soil quality, crop growth, water resources, and ecosystems, necessitating remediation and remediation.
[0003] The uniform stirring device for contaminated soil remediation is a device used to mix and stir soil and pollutants during the contaminated soil remediation process. Through the stirring device, the polluted soil and the reagent can be evenly mixed to make their distribution more uniform, which is conducive to subsequent treatment and remediation work.
[0004] Existing uniform stirring devices for contaminated soil remediation typically pour the contaminated soil into a feed hopper, and then use a stirring rod and its stirring blades to stir the contaminated soil and the reagent. However, the existing stirring method is not very efficient when stirring agglomerated soil, and the stirring rod usually only rotates and stirs the soil simply through a single stirring rod, resulting in poor uniformity of the stirring effect, which brings many inconveniences to actual use.
[0005] Moreover, during the mixing process, it is usually necessary to regularly clean the mixing rod and the mixing chamber to prevent excessive accumulation of contaminated soil on the agitator, which may cause the agitator to rotate poorly or become blocked. However, existing agitators are usually installed in the mixing chamber, which makes it very inconvenient for personnel to clean, causing great trouble to actual use.
[0006] In view of this, we propose a uniform stirring device for contaminated soil treatment. Utility Model Content

At this time, the stirring motor 310 can be started to drive the stirring rod 1 340 and the stirring rod 2 350 to rotate. During the rotation process, the gears 351 at the ends of the multiple stirring rods 350 will be meshed and driven in the tooth grooves 390 on the inner wall of the sleeve barrel 360, so that the multiple stirring rods 350 can rotate independently. Stirring better improves the efficiency of soil mixing, and the contaminated soil can be fully mixed more evenly by spraying the agent through multiple infusion cylinders 180. When discharging the soil, multiple hydraulic cylinders 150 can be started to drive the sleeve barrel 360 and the fixed circular plate 300 to move outward so that the soil can be discharged. In the process of discharging the soil, the rubber scraper 380 can clean the inner wall of the stirring chamber 160, and the stirring rod 1 340 and the stirring rod 2 350 can also be moved out of the stirring chamber 160, which makes it easier for personnel to clean the soil on the stirrer, improves the cleaning efficiency of personnel, and reduces the labor burden of personnel.
