Description

Technical Field

[0001] This utility model relates to the field of soil treatment technology, specifically a solidification and stabilization device for treating heavy metal contaminated soil. Background Technology

[0002] Heavy metal pollutants in soil mainly include mercury, cadmium, lead, copper, chromium, arsenic, nickel, iron, manganese, and zinc. Although arsenic is not classified as a heavy metal, its behavior, sources, and hazards are similar to those of heavy metals, so it is usually discussed in the category of heavy metals. In terms of plant needs, metallic elements can be divided into two categories: elements not needed for plant growth and development but with significant health risks, such as cadmium, mercury, and lead; and elements necessary for normal plant growth and development, which also have certain physiological functions for humans, such as copper and zinc, but excessive amounts can cause pollution and hinder plant growth and development. The solidification and stabilization process for treating heavy metal-contaminated soil generally includes compacting the treated soil using compaction equipment.

[0003] During use, existing compaction equipment for treating heavy metal contaminated soil will have a large amount of soil impurities adhering to the surface of its roller components. Long-term adhesion of soil impurities will cause rust on the roller surface, reducing the service life of the roller. In addition, the soil needs to be cleaned manually by the staff, which is very inconvenient.

[0004] Therefore, those skilled in the art have provided a solidification and stabilization device for treating heavy metal contaminated soil to solve the problems mentioned in the background art. Utility Model Content

By setting up a cleaning mechanism, the surface of the roller can be automatically cleaned during use, preventing soil from adhering to the surface and causing corrosion, thus greatly improving the service life of the roller. Secondly, it eliminates the need for manual cleaning of the soil on the surface of the roller, which is very convenient. Furthermore, by setting up a collection mechanism, the swept-off soil can be collected in a concentrated manner, facilitating subsequent soil treatment by staff, saving time and effort, and indirectly improving the compaction efficiency of the device, thereby solving the problems mentioned in the background art.

[0020] Please see Figures 1-4 In this embodiment of the present invention, a solidification and stabilization device for treating heavy metal contaminated soil includes a fixed frame 1. Rotating columns 3 are rotatably connected to the inner walls on both sides of the fixed frame 1. A roller 4 is fixedly connected between the two rotating columns 3. The roller 4 can rotate based on the fixed frame 1 through the rotating columns 3. A connector 2 is fixedly connected to the outer wall on one side of the fixed frame 1. The connector 2 can be connected and installed with the main body of a road roller. When the main body of the road roller moves, it can drive the roller 4 to rotate. It can be used to compact the treated soil. Compaction can improve the density of the soil, enhance the strength of the solidified soil, and improve the soil treatment effect.

[0021] A first groove 5 is provided on the side wall of the fixed frame 1. A first wheel 6 is sleeved on and fixedly connected to the rotating column 3. The first wheel 6 is located inside the first groove 5. A second wheel 7 is rotatably connected to the inner wall of the first groove 5. The first wheel 6 and the second wheel 7 are connected by a belt 8. When the roller 4 rotates and drives the rotating column 3 to rotate, it can drive the first wheel 6 and the second wheel 7 to rotate. A rotating rod 9 is fixedly connected to the second wheel 7. A large number of cleaning bristles 10 are fixedly connected to the outer wall of the rotating rod 9. The cleaning bristles 10 are in full contact with the outer wall of the roller 4. The cleaning bristles 10 can sweep off the soil adhering to the surface of the roller 4.

[0022] A positioning block 11 is fixedly connected to the side wall of the fixed frame 1. A spring column 12 is fixedly connected to the lower end of the positioning block 11. A striking element 13 is fixedly connected to the lower end of the spring column 12. The striking element 13 is in full contact with the rotating rod 9. An arc-shaped block 14 is fixedly connected to the outer wall of the rotating rod 9. When the rotating rod 9 rotates, it can drive the arc-shaped block 14 to rotate. When the arc-shaped block 14 moves to contact the striking element 13, it can push the striking element 13 to move and squeeze the spring column 12. When the arc-shaped block 14 separates from the striking element 13, the spring column 12 pops out quickly, which drives the striking element 13 to strike the rotating rod 9, causing the soil impurities adhering to the cleaning bristles 10 to fall off, thus achieving the cleaning effect.

[0023] A limiting groove 17 is provided at the lower end of the fixed frame 1. A limiting strip 16 is slidably connected to the inner wall of the limiting groove 17. A collection cylinder 15 is fixedly connected to the lower end of the limiting strip 16. The collection cylinder 15 is located directly below the contact point between the cleaning brush bristles 10 and the roller 4. The swept dust can fall into the inside of the collection cylinder 15 for easy subsequent processing. A fixing magnet 18 is embedded in the limiting strip 16. The collection cylinder 15 can be fixed to the fixed frame 1 by the fixing magnet 18, which makes it easy to disassemble and assemble the collection cylinder 15.

[0024] The working principle of this utility model is as follows: When it is necessary to compact the treated soil, firstly, the fixed frame 1 with roller 4 can be installed on the compactor body through the connector 2. Then, the compactor body moves and drives the roller 4 to rotate, thereby compacting the soil. When the roller 4 rotates, it also drives the rotating column 3 to rotate synchronously. At this time, the first wheel 6 will rotate with the rotating column 3. Then, under the action of the belt 8, it drives the second wheel 7 to rotate. When the second wheel 7 rotates, it drives the rotating rod 9 to rotate. At this time, the cleaning brush 10 rotates with the rotating rod 9. The rotation of the cleaning brush 10 can sweep the surface of the roller 4, which can sweep off the soil adhering to the surface of the roller 4. When the rotating rod 9 rotates, it also drives the second wheel 7 to rotate. When the curved block 14 rotates, it moves to contact the striking element 13, which in turn pushes the striking element 13 to move and squeeze the spring column 12. When the curved block 14 separates from the striking element 13, the spring column 12 pops out quickly, which in turn drives the striking element 13 to strike the rotating rod 9, causing the soil impurities on the cleaning brush bristles 10 to fall off, thus achieving a cleaning effect without affecting the cleaning effect of the cleaning brush bristles 10. The swept-off soil impurities can fall into the inside of the collection cylinder 15. When it is necessary to remove the soil from the inside of the collection cylinder 15, simply pull the limiting strip 16 out of the limiting groove 17 to remove the collection cylinder 15 from the fixed frame 1, which facilitates the subsequent centralized processing of the soil.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
