Description

Soil remediation machine and method based on local caking detection crushing and replenishing liquid

Technical Field

The invention relates to the field of environmental protection, in particular to a soil remediation machine and a remediation method based on local caking detection crushing and replenishing liquid.

Background

In the soil remediation work, two important processes of crushing the caking in the soil and adding the chemical remediation liquid to the soil to be remediated are indispensable. The operation of adding the repair liquid is often performed in a stirring device in consideration of sufficient distribution of the repair liquid, and a stirring rod in the stirring device generally also serves as a crushing function. Because the crushing of the stirring rod is a crushing mode with single-side stress, the crushing effect is often not ideal, and the operation of clamping and crushing by the crushing plates is often required to be carried out after stirring.

However, since the impact crushing is a non-differential crushing, that is, the non-caking part or the soil part which has been crushed to an acceptable size by the stirring rod will be subjected to impact crushing together with the caking part, which not only greatly prolongs the time length of the treatment process, but also increases the energy consumption of operation, and is not ideal in terms of saving processes and energy.

On the other hand, as the density of the caking part is far greater than that of the soil of the non-caking part, a part of the caking surface even produces a compact film, and the liquid permeability of the caking surface is poor, the caking part which can not be broken in the stirring process can not be penetrated by sufficient repairing liquid; if the repair liquid is added again in a fully covering manner after the subsequent independent clamping and crushing device is used for treatment, quite a lot of repair liquid is wasted undoubtedly.

Based on the two points, it is of practical positive significance to develop a soil remediation device which has a local caking detection function and can independently crush the caking and add remediation liquid.
