When the soil after screening passes through second discharge gate 53, agitator motor 73 drives (mixing) shaft 71 and rotates for (mixing) shaft 71 drives puddler 72 and stirs soil, thereby further breaks up soil, and then promotes the degree of softness that soil fell to on conveyer 8, so that spray mechanism 9 fully sprays soil, has promoted the treatment of soil effect

The implementation principle of the leaching treatment system for soil pollution treatment in the embodiment of the application is as follows: in the process of treating the polluted soil, an operator firstly pours the soil into the storage hopper 11. Then an operator starts the winding mechanism to clean the flexible sundries in the soil, when the sundries wound on the winding drum 21 pass, the operator starts the pushing piece 4, so that the pushing piece 4 pushes the materials into the collecting box 12, and the operator can further process the sundries conveniently.

The soil then enters a vibrating screen 51, and after being screened by the vibrating screen 51, the particulate matter in the soil is separated from the soil. At this time, the particulate matter enters the secondary screening mechanism 6 through the first discharge hole 52, so that the secondary screening mechanism 6 further screens the soil on the surface of the particulate matter. Meanwhile, the screened soil falls onto the conveyor 8 through the second discharge hole 53, so that the conveyor 8 conveys the soil, and the soil is leached through the spraying mechanism 9, so that the soil leaching effect is achieved. And finally, performing solid-liquid separation on the washed soil by an operator through a filter press to achieve the effect of treating the soil.

The embodiment of the application also discloses an arrangement method of the leaching treatment system for treating the soil pollution.

The arrangement method of the leaching treatment system comprises the following steps:

s1: an operator pours soil into the storage hopper, starts the winding assembly to wind flexible sundries in the soil, then the operator stops the winding assembly periodically, and starts the pushing member, so that the pushing member pushes the sundries into the collecting box, and the sundries cleaning effect is achieved;

s2: after the flexible impurities in the soil are cleaned, the soil falls into the vibrating screen, so that the vibrating screen splits the soil and separates granular impurities in the soil from the soil;

s3: the particles separated from the soil enter the drying bin through the first discharge hole, so that the sieve tray vibrates the particles to achieve the effect of secondary soil screening, the separation effect of the soil and the particles is improved, and finally the screened soil is discharged onto a conveyor through the discharge hole;

s4: the soil screened out by the vibrating screen falls onto the conveyor through the second discharge hole, and the stirring motor drives the stirring shaft to stir the soil so as to increase the softness of the soil;

s5: an operator starts a spraying mechanism to drip wash the soil;

s6: and carrying out solid-liquid separation on the washed soil through a filter press.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
