soil, then the soil is separated from the surface of the conical box 354 under the action of centrifugal force and moves towards the inner surface of the filter cloth 33 in a linear mode until the soil is attached to the inner surface of the filter cloth 33 under the action of the adhesive force and the centrifugal force, then the filter cloth 33 carries the soil adhered on the filter cloth to move circularly, then the telescopic plate 366 applies force to the scraper 367 under the action of elastic force of the elastic sheet 364, the scraper 367 is enabled to cling to the inner wall of the filter cloth 33, then the scraper 367 moves relative to the soil on the inner wall of the filter cloth 33, the soil scraped on the inner wall of the filter cloth 33 is scraped, then the scraped soil moves downwards under the action of gravity until the soil falls on the surface of the conical box 354 again, in the process, the water knife sprayed by the spray head 12 back washes the filter cloth 33, soil adhered on the inner surface of the filter cloth 33 is washed away, the filter cloth 33 after being washed by the spray head 12 has good permeability, the dehydration speed of the soil is increased, then heavy metal in the soil flows out along with the repairing agent, the heavy metal remained in the soil is less, the repairing effect of the soil is improved, and meanwhile, the whole soil entering the filter cloth 33 receives the high-speed repairing, the high-speed sprayed restoration agent jet flow can carry out secondary crushing on the soil, the contact area between the soil and the restoration agent is increased, the soil restoration effect is improved, then the sewage generated by washing the soil penetrates through the filter cloth 33 and the conical stainless steel net framework 31 under the action of centrifugal force and is gathered in the separating device 7, then the heavy metal cations are concentrated by the interception action of the anion exchange membrane 72 on the cations, so that the heavy metal cations in the restoration agent are concentrated in the restoration agent in the separating device 7, the amount of the sewage containing the heavy metals is greatly reduced, the workload of sewage purification is reduced, the cost of soil restoration is reduced, the processes are repeated, the soil is repeatedly washed, dehydrated and crushed until the soil is directly passed through the conical guide ring 34 and the conveying cylinder 61 after being separated from the inner wall of the filter cloth 33 and falls on the top surface of the conveying belt 507 to be conveyed out, and finishing the soil remediation work.
The above; but are merely preferred embodiments of the invention; the scope of the invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the invention are equally replaced or changed; are intended to be covered by the scope of the present invention.
