Description
Technical Field
The invention relates to the technical field of soil remediation, in particular to crushing and screening equipment for land treatment, which is used for treating polluted soil.
Background
The focus of contaminated soil remediation is to reduce the content of contaminants in the soil, convert the soil contaminants into less toxic or non-toxic materials, or block the transfer pathway of soil contamination in the ecosystem, thereby reducing the damage of soil contaminants to the environment, human body, or other organisms. The contaminated soil remediation technology can be divided into in-situ remediation and ex-situ remediation, wherein in-situ remediation is to degrade and attenuate pollutants by in-situ treatment of deep contaminated soil, and expensive ground environment engineering infrastructure and remote transportation are not required to be constructed. Ex-situ remediation refers to a technique in which contaminated soil is excavated from the site where the contamination occurred, and is remediated either in situ or after transport. Ex-situ remediation is suitable for treating sites with higher pollution concentrations, greater risks and less contaminated soil. And, compared with in-situ repair, ex-situ repair has the advantages of lower environmental risk and higher predictability of system processing than in-situ repair.
In the soil ex-situ remediation technology, the method mainly comprises two major steps of soil pretreatment and mixing of the soil remediation agent, namely, the pretreatment of the soil is also involved before the specific polluted soil is remediated, namely, the excavated soil is crushed and screened into small particles, so that the soil remediation agent can be conveniently mixed. The soil pretreatment step is mainly completed through the sieving and crushing bucket for repairing the soil, the sieving and crushing bucket for repairing the soil can be directly loaded on an excavator for use, crushing and sieving of the soil can be completed in one step, and the sieving and crushing machine is efficient, convenient and low in cost.
Initially, the soil pretreatment step and the mixing of soil restoration agents in the soil ex-situ remediation technique were often performed separately and separately, which resulted in a low degree of integration of the soil ex-situ remediation system. In order to solve the problem, in the prior art, an integrated device for crushing, screening and mixing a medicament for soil is provided, for example, a ALLU bucket for repairing the ectopic soil disclosed in patent CN215430799U is provided with a spraying assembly on a bucket body, and the medicament for repairing can be sprayed into the soil when the soil to be repaired exists in the bucket body. However, in the foregoing patents, the spraying assembly is aimed at spraying soil restoration agent to the soil before crushing, at which time the soil has not been crushed, which makes the restoration agent insufficient to contact the soil.
To the problem that exists among the aforesaid patent, patent CN213103758U discloses a broken screening fill for soil remediation, and it sets up at the dorsal part of scraper bowl and sprays the subassembly, can spray the repair liquid to the soil piece that falls after broken screening to make soil repair liquid can fully contact with the soil piece after the breakage.
However, in the soil process, the remediation agents used for soil remediation are often of a solid (e.g., solid powder) nature, such as heavy metal stabilizers. In the structure disclosed in the above-mentioned known patent, the spraying units integrally provided on the bucket are all liquid agents, i.e., liquid soil restoration materials, which cannot be applied to the solid chemical materials required for the soil restoration process. In addition, in the bucket with the integrated structure disclosed in the above patent, an additional energy consumption device, such as a booster pump, is required to be arranged corresponding to the spraying assembly, so that the spraying of the applicable liquid agent can be realized, the self weight of the bucket is increased, the energy consumption of the bucket is increased, and the additional energy consumption is required for the devices to work, so that the economical saving type is poor.
