Description

Technical Field

[0001] This utility model relates to the field of soil remediation equipment technology, specifically a screening device for soil remediation. Background Technology

[0002] Soil remediation is a technical measure to restore contaminated soil to its normal function. In the soil remediation industry, there are over one hundred existing technologies, with more than ten commonly used, broadly categorized into physical, chemical, and biological methods. Soil remediation implementation methods are divided into "in-situ remediation" and "ex-situ remediation." The former refers to directly remediating the contaminated soil at the contaminated site, while ex-situ remediation requires excavating the soil (in many cases, the soil is excavated and remediated at a nearby site; this is also considered ex-situ remediation).

[0003] In the process of soil remediation, it is necessary to remove impurities from the soil. However, the common conical soil screening device used for soil remediation has poor screening effect and low screening efficiency. Moreover, during the screening process, soil accumulation in local areas can easily cause clogging of the screen plate, requiring frequent shutdowns to clean the screen plate, which greatly reduces the working efficiency of the soil screening device. Therefore, this utility model proposes a screening device for soil remediation to solve the above problems. Utility Model Content
