In-situ chemical oxidation repair device for organic contaminated soil

Technical Field

The invention relates to the technical field of soil remediation, in particular to an in-situ chemical oxidation remediation device for organic contaminated soil.

Background

The polluted soil remediation is a technical measure which reduces the concentration (activity) of soil pollutants by adopting physical, chemical, biological and ecological principles and adopting artificial regulation measures, so as to realize the harmlessness and stabilization of the pollutants and achieve the expected detoxification effect. Theoretically feasible repair technologies include phytoremediation, microbial remediation, chemical remediation, physical remediation, comprehensive remediation and the like. Most soil prosthetic devices carry out soil when restoreing at present and carry out the separation to the bold hard piece soil that contains in the soil and bold stone, and a large amount of soil and the easy adhesion of stone are in the inner wall of device, can't lead to long-time work after separation remediation efficiency greatly reduced to can't carry out the collection of concentrating to the stone after the separation and the soil block and deposit, lead to later stage staff's work burden greatly increased.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: in order to overcome the defects of the prior art, the invention provides the in-situ chemical oxidation remediation device for the organic polluted soil, which can effectively separate massive hard soil and massive stones from the soil and effectively reduce the soil adhesion condition on the inner wall of the remediation device when the soil is filtered and separated in soil remediation.

The technical scheme adopted by the invention for solving the technical problems is as follows: an in-situ chemical oxidation remediation device for organic contaminated soil comprises a box body, wherein a rotating rod is rotatably arranged in the box body, a motor for driving the rotating rod to rotate is further arranged on the box body, and a soil separating and shaking-off cleaning mechanism is arranged in the box body; the soil separating and shaking-off cleaning mechanism comprises a poking plate, a shovel plate, a rotating block and a connecting plate, wherein the poking plate is arranged on the rotating rod and synchronously rotates along with the rotating rod, the shovel plate and the connecting plate are respectively fixed on the outer wall of the rotating block, the rotating block is hinged to the inner wall of one side of a box body, a separating cavity for the shovel plate to rotate is arranged on the box body corresponding to the motion track of the shovel plate, a resetting cavity for the connecting plate to rotate is arranged on the box body corresponding to the motion track of the connecting plate, a small elastic plate is further arranged in the resetting cavity of the box body, one end of the small elastic plate is fixed to the inner wall of the box body of the resetting cavity, and the other end of the small elastic plate is fixed to the connecting plate; the vibrating scraping cleaning mechanism comprises an elastic rope and a scraping plate, the sliding plate is arranged on the surface of the poking plate in a sliding mode, one end of the elastic rope is connected with the outer end of the scraping plate, and the other end of the elastic rope is connected with the scraping plate.

In the above scheme, through the setting of the clean mechanism of soil separation shake-off, through the rotation of bull stick, can drive the stirring board and stir soil, hold soil and the stone of large granule and rotate upward movement. And soil and the stone landing of the large granule that will hold after moving to the top to shovel board department, the shovel board is stirring the board and is driving and little elastic sheet elastic action down, does the reciprocating rotation of certain angle, realizes outwards stirring the operation of transporting in the soil and the stone that will fall on the shovel board surface, is convenient for collect the operation to the concentration of the soil and the stone of isolating. Meanwhile, the design of the vibrating scraping and cleaning mechanism can ensure that the scraper slides along the surface of the poking plate in a reciprocating manner under the action of gravity and elastic force of the elastic rope when the poking plate rotates, so that the floating soil remained on the surface of the shovel plate is scraped, and the self-cleaning operation of the surface of the poking plate is realized.

The soil separating and shaking-off cleaning mechanism further comprises a sliding sleeve and hinged plates, the surface of the shovel plate is hinged with a plurality of hinged plates, an air cavity is formed below the shovel plate corresponding to each hinged plate, the sliding sleeve is arranged on the connecting plate in a sliding manner, air grooves are formed in the shovel plate, the rotating block and the connecting plate in a penetrating manner, one end of each air groove is communicated with the air cavity, the other end of each air groove is communicated with the sliding sleeve, and the sliding sleeve axially slides along the connecting plate and extrudes air in the air grooves and the air cavities; the inner wall of the reset cavity is provided with a plurality of inclined blocks at intervals along the motion track of the bottom of the sliding sleeve on the inner wall of the reset cavity, and the sections of the inclined blocks along the surface where the motion track is located are triangular.
