Description

Technical Field

[0001] The utility model belongs to the technical field of contaminated soil treatment, and in particular relates to contaminated soil treatment equipment. Background Art

[0002] As people's quality of life improves, the amount of domestic and industrial waste generated every day increases. If these wastes are discharged directly into the land without treatment, they will pollute the land. Whether for environmental protection or for land reuse, these polluted lands need to be purified. When treating these contaminated soils, various agents often need to be added to degrade harmful substances in the soil.

[0003] When treating the contaminated soil, a contaminated soil treatment device is needed. For example, Chinese utility model patent CN220258152U discloses a contaminated soil treatment device. The contaminated soil to be treated is added to the inside of the device from the top of the hopper. Then the operator starts the servo motors at various locations, and the servo motor a at the top drives the stirring shaft to rotate, thereby performing a preliminary crushing operation on the lumps in the contaminated soil. Then the crushed soil falls onto the sliding screen plate, and the convex point turntable arranged at the bottom of the sliding screen plate is driven to rotate by the servo motor b, so that the bottom of the sliding screen plate is continuously hit, so that the sliding screen plate continuously vibrates up and down in the chute, thereby completing the screening of foreign matter such as stones in the soil, so that the stones will be discharged from the discharge port a, and the screened soil will be crushed more finely by the crushing roller through the sieve grid, so that large pieces of contaminated soil can be crushed to smaller particle sizes, making the soil more uniform, which is conducive to subsequent dosing and stirring treatment or other treatment operations.

[0004] Although the above-mentioned prior art can separate the gravel in the contaminated soil to be treated, if the contaminated soil is relatively wet, it cannot be broken up by the stirring shaft and cannot be screened by the sliding screen plate, thereby limiting its use. Utility Model Content
