Soil remediation machine and remediation method based on local agglomeration detection, fragmentation and replenishment

Abstract

The invention discloses a soil remediation machine based on local caking detection crushing and replenishing liquid. The device comprises a stirring rod detection assembly, a local clamping crushing assembly, a repairing liquid local supplementing assembly and a repairing liquid nozzle protection assembly, has a local caking detection function, can separately crush cakes and add repairing liquid,and has a relatively good popularization value.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a soil remediation machine and a remediation method based on local agglomeration detection for crushing and liquid replenishment. Background technique [0002] In soil remediation work, breaking up the agglomerates in the soil and adding chemical remediation fluid to the soil to be remediated are two important processes that are essential. For the sake of sufficient distribution of repair fluid, the operation of adding repair fluid is often carried out in a stirring device, and the stirring rod in the stirring device generally also acts as a crushing function. Since the crushing of the stirring rod is essentially a single-sided crushing method, the crushing effect is often not ideal, and it is often necessary to carry out the crushing operation of the crushing plate alone after stirring. [0003] However, since this kind of pinch crushing is an indiscriminate crushing, th...

Problems solved by technology

Since the crushing of the stirring rod is essentially a single-sided crushing method, the crushing effect is often not ideal, and it is often necessary to carry out the crushing operation of the crushing plate alone after stirring.

[0003] However, since this kind of pinch crushing is an indiscriminate crushing, that is, the non-caking part or the soil part that has been crushed to a qualified size by the stirring rod will be crushed together with the agglomerated part, which actually not only greatly prolongs the The time length of the processing process is increased, and the energy consumption of the operation is also increased, which is not ideal in terms of saving procedures and energy saving

[0004] On the other hand, because the density of the agglomerated part is much higher than that of the non-agglomerated part of the soil, a part of the agglomerated surface even produces a dense film, which has poor seepage performance, so the agglomerated part that cannot be crushed during stirring often has to be However, if the repair liquid is fully covered after being processed by the subsequent independent pincer crushing device, it will undoubtedly cause a lot of waste of repair liquid
