[0027] Furthermore, a collecting plate 13 is installed in the middle of each stirring frame 10, and a plurality of through grooves are opened in the middle of the collecting plate 13. A front baffle 16 is provided on one side of the through groove, and a filter screen 12 is installed on the other side through a snap-in groove 131, and an inclined groove 17 is provided below the filter screen 12.

[0028] Furthermore, a collecting box 2 is installed at the bottom of the frame 1, and a leaching chamber 6 is arranged directly above the collecting box 2. The upper part of the leaching chamber 6 is fixedly connected to the equipment cabin 3, wherein the soil after elution in the leaching chamber 6 can be collected through the collecting box 2.

[0029] Furthermore, a material channel 31 is provided inside the equipment cabin 3, one side of the material channel 31 is connected to the feed port 4, and the other side is connected to the top of the elution chamber 6;

[0030] Furthermore, an electric hatch 32 is provided on one side of the middle of the material channel 31. The electric hatch 32 is provided with a motor for driving, thereby satisfying the unloading function of the contaminated soil.

[0031] Furthermore, the output end of the driving motor 5 extends into the material channel 31 and is driven and connected to a stirring shaft 41. One end of the stirring shaft 41 passes through the bottom of the equipment cabin 3 and extends into the elution chamber 6. The bottom end of the stirring shaft 41 is rotatably mounted on a partition plate 18 arranged inside the elution chamber 6.

[0032] Furthermore, an electric hatch 2 14 is provided on one side of the partition plate 18. A motor for driving is provided inside the electric hatch 2 14, thereby satisfying the discharge function of the leached soil.

[0033] Furthermore, an inclined filter plate 15 is provided above the waste liquid hole 9. The inclined filter plate 15 can effectively achieve solid-liquid separation.

[0034] Furthermore, a plurality of rinsing nozzles 10 are disposed on the top wall of the material channel 31 , and a rinsing chamber 6 is disposed directly below the rinsing nozzles 10 .

[0035] Furthermore, a plurality of clamping blocks 121 are installed on the outer side of the filter screen 12 , and the filter screen 12 is clamped and installed in a clamping groove 131 opened on one side of the collecting plate 13 through the clamping blocks 121 .

[0036] Furthermore, a gap is left between the filter screen 12 and the front baffle 16 .

[0037] In this embodiment, the contaminated soil to be processed is introduced through the feed port 4 on one side of the equipment cabin 3. At this time, the electric hatch 1 32 is opened and the contaminated soil is allowed to enter the elution chamber 6 through the material channel 31. The stirring shaft 41 in the elution chamber 6 is driven by the driving motor 5 to rotate and mix. The stirring shaft 41 drives multiple stirring racks 11 to stir. During the stirring process, the collecting plate 13 in the middle of the stirring rack 11 pours the soil into the front baffle 16, and realizes solid-liquid separation between the front baffle 16 and the filter screen 12, so that the debris is blocked by the filter screen 12 between the two, and the soil will gradually seep out of the filter screen 12 and complete the debris filtration during the continuous elution of the elution liquid. At the same time, after the elution is completed, the electric hatch 2 14 set on one side of the bottom partition plate 18 is opened, and the eluted soil is introduced into the bottom of the elution chamber 6, and the solid-liquid separation is realized through the inclined filter plate 15 set at the bottom, and the waste liquid is introduced into the waste liquid hole 9, and the soil falls into the collection box 2 through the discharge port 8.

[0038] Among them, during actual use, the filter 12 is installed in the clamping groove 131 opened on one side of the collection plate 13 through the clamping block 121, and is locked by a bolt. During subsequent use, the maintenance door on one side of the elution chamber 6 can be opened to replace the filter 12 to ensure efficient filtering effect.

[0039] In actual use, when the soil enters the elution chamber 6, the multiple elution nozzles 10 arranged directly above the elution chamber 6 cooperate with the cleaning liquid cylinder 7 to spray, so that the elution liquid is mixed with the soil.

[0040] In the utility model, when the contaminated soil enters the elution chamber 6, the contaminated soil is stirred by the continuously stirring stirring rack 11, so that the elution liquid and the soil are fully mixed. At the same time, through the setting of the collecting plate 13, the filter screen 12, the front baffle plate 16 and other components arranged in the stirring rack 11, the large and small debris in the soil are effectively separated, filtered and collected during the mixing process, thereby improving the elution effect of the soil and improving the soil remediation efficiency.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
