Environment-friendly purification device for treating soil contaminated by heavy metal

Abstract

The invention discloses an environment-friendly purification device for treating soil contaminated by heavy metal. The device comprises a cart body and a shovel loader, the shovel loader is located atthe left side of the cart body, and a rotation cavity is formed in the left side of the cart body; a soil shoveling mechanism is arranged in the rotation cavity and connected with the shovel loader and the cart body, through rotation of the soil shoveling mechanism, soil shoveled by the shovel loader can be conveyed into the cart body, and a crushing cavity for receiving the soil is formed in theupper side of the rotation cavity. The device can be used for treating the soil contaminated by the heavy metal, the mechanisms in the whole device can be in simultaneous linkage and can be operatedautomatically, the whole soil treatment process is easily and conveniently conducted, the efficiency is obviously improved, and the situation is avoided that the soil is collected, taken to a specialtreatment site for treatment and then returned to the original place. Treatment can be directly conducted on the local area with the contaminated soil.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to a green purification device for treating heavy metal polluted soil. Background technique [0002] At present, due to the frequent occurrence of non-standard dumping and disposal of garbage, the soil in some areas has been seriously polluted by heavy metals. The contaminated soil is difficult to use for planting crops and needs to be treated before it can be used. The soil is collected first, transported to a special treatment plant for degradation treatment, adding a reaction solution capable of reacting with heavy metals to the contaminated soil, and then undergoing sedimentation and filtration treatment to separate heavy metal substances, and finally the soil can be returned to the local area , there are many procedures, the amount of personnel used is very large, and the transportation back and forth is very cumbersome. Therefore, a green purification device that can di...

[0002] At present, due to the frequent occurrence of non-standard dumping and disposal of garbage, the soil in some areas has been seriously polluted by heavy metals. The contaminated soil is difficult to use for planting crops and needs to be treated before it can be used. The soil is collected first, transported to a special treatment plant for degradation treatment, adding a reaction solution capable of reacting with heavy metals to the contaminated soil, and then undergoing sedimentation and filtration treatment to separate heavy metal substances, and finally the soil can be returned to the local area , there are many processes, the amount of personnel used is very large, and the transportation back and forth is very cumbersome. Therefore, a green purification device that can directly treat contaminated soil in heavy metal-contaminated soil areas is needed. The device must have a treatment process that includes all mechanisms. The purification process of the device needs to be simple and convenient
