[0023] The following will Figures 1 to 5 be described in detail with reference to the attached drawings. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a leaching and remediation device for repairing heavy metal contaminated soil through improvement, as Figures 1 - 5As shown in the figure, a flushing and remediation device for repairing heavy metal-contaminated soil includes a spraying vehicle 1. A mixing drum 3 is arranged on the spraying vehicle 1. Symmetrical convex plates 9 are fixedly arranged on the outer walls on both sides of the mixing drum 3. A through cavity 10 is formed in the middle of the convex plate 9. A swing motor 11 is installed on the top of the convex plate 9. The output end of the swing motor 11 is connected with a swing arm 12. The swing arm 12 is located in the through cavity 10, and the bottom of the swing arm 12 is connected with a driving rod 13. A swing tooth fan 14 is movably installed at the bottom of the convex plate 9. An engagement groove 15 matching with the driving rod 13 is formed in the middle of the swing tooth fan 14. A rotating shaft 17 is also movably installed on the convex plate 9. A swing gear 16 meshing with the swing tooth fan 14 is installed at the bottom of the rotating shaft 17. The top of the rotating shaft 17 is connected with a spraying plate 18. Multiple spray pipes 19 are arranged at the bottom of the spraying plate 18. A flow channel 22 is formed inside the spray pipe 19. The flow channel 22 is communicated with the outside through an arc channel 23 and an atomization channel 25 in sequence. Both the arc channel 23 and the atomization channel 25 are conical structures, and the arc channel 23 and the atomization channel 25 are connected through a connecting channel 24.

The guide plates 26 play a role in guiding the movement of the fluid, causing the atomized small water droplets to rotate. Due to the action of centrifugal force, the liquid will form a hollow cone or hollow cylinder shape. This rotating state can cause the gas to generate shear force and turbulence effect, thereby accelerating the atomization of the liquid.
