Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, specifically to an ecological restoration method and apparatus for various types of land soil. Background Technology

[0002] Soil remediation refers to the technical measures taken to restore contaminated soil to its normal function. In the soil remediation industry, there are over one hundred existing technologies, with more than ten commonly used, broadly categorized into physical, chemical, and biological methods. Since the 1980s, many countries worldwide, especially developed countries, have formulated and implemented contaminated soil remediation plans, thus giving rise to a burgeoning soil remediation industry.

[0003] Currently, there are various methods for soil remediation, such as chemical leaching. This method involves injecting the leaching solution into the contaminated soil layer under gravity using chemical or biochemical solvents that promote the dissolution or migration of pollutants in the soil environment. The solution containing pollutants is then extracted from the soil for separation and wastewater treatment. However, in existing technologies, the remediation solution generally relies on natural infiltration under gravity, resulting in low mixing efficiency between the remediation solution and the soil, thus reducing the soil remediation efficiency. Therefore, we propose an ecological remediation method and device for various types of land soil. Summary of the Invention

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please see Figure 1 and Figure 2 Example 1 illustrates an ecological restoration device for various types of land soil, comprising a restoration tank 1, a discharge pipe 2 connected to the bottom of the restoration tank 1, and an inlet pipe 3 connected to the top of the restoration tank 1, one end of the inlet pipe 3 connected to a feed hopper 4, and a support leg 48 installed at the bottom edge of the restoration tank 1; it also includes a drug dispensing component 5, which is installed inside the restoration tank 1 and extends outward from the restoration tank 1 for adding restoration drugs to the soil; an agitation component 6, which is installed inside the restoration tank 1 for agitating the soil; and a cleaning component 7, which is installed inside the restoration tank 1 and connected to the agitation component 6 for cleaning the inner wall of the restoration tank 1 and the agitation component 6.

[0036] Please see Figure 3 and Figure 4 The dispensing assembly 5 shown in the figure includes an outer tube 8 installed inside and fixedly connected to the repair tank 1. A rotating tube 9 is rotatably connected inside the outer tube 8. Both the rotating tube 9 and the outer tube 8 have through holes 10. A filter cloth 11 is installed between the rotating tube 9 and the outer tube 8. A connecting tube 12 is fixedly connected to the top end of the rotating tube 9. A drug inlet tube 13 extending to the outside of the repair tank 1 is rotatably connected to the top end of the connecting tube 12. A rotating component 14 is connected to the outer surface of the rotating tube 9.

[0037] Please see Figure 3 and Figure 4 The rotating component 14 shown in the figure includes a half-stroke gear 15 fixed to the outer surface of the rotating tube 9. A torsion spring 16 is fixedly connected to the bottom end of the half-stroke gear 15. A connecting ring 17 fixedly connected to the outer sleeve tube 8 is fixedly connected to the other end of the torsion spring 16. A first spur gear 18 meshes with the outer side of the half-stroke gear 15. A rotating shaft 19 is fixedly connected to the axis of the first spur gear 18. A driving component 20 is connected to one end of the rotating shaft 19.

[0038] Please see Figure 5 and Figure 6The agitation assembly 6 shown in the figure includes a connecting frame 21 installed on the repair tank 1. The connecting frame 21 is rotatably connected to the outer tube 8, and multiple agitation rods 22 are fixedly connected to the connecting frame 21. A connecting sleeve 23 fitted onto the outer surface of the outer tube 8 is fixedly connected to the agitation rod 22. A second spur gear 24 is fixedly connected to the top of the connecting sleeve 23. A third spur gear 25 fixedly connected to the rotating shaft 19 meshes with the outer side of the second spur gear 24.

[0039] An ecological restoration method for various types of land soil includes the following steps:

[0040] S1: Collect the soil that needs to be repaired, and then dry the collected soil.

[0041] S2: Crush the dried soil;

[0042] S3: Filter the crushed soil to remove impurities such as tree roots and grass roots from the soil, and then wait for the soil to be repaired.

[0043] S4: The soil to be remediated is transported to the soil remediation equipment, and remediation solution is delivered into the soil;

[0044] S5: The remediated soil is then subjected to solution extraction, drying, grinding, and pollutant testing to obtain the remediated soil.

[0045] In this embodiment, the filtered soil to be repaired is transported to the repair tank 1 through the feed hopper 4. The inlet pipe 13 is connected to the pipeline for transporting the repair fluid. The inlet pipe 13 is connected to the pipe 12 and the rotating pipe 9 to transport the repair fluid. The drive unit 20 is activated, which drives the rotating shaft 19 to rotate. This rotation drives the first spur gear 18 to rotate, which in turn drives the half-stroke gear 15 to rotate, thus rotating the rotating pipe 9. This causes the rotating pipe 9 to align with the through hole 10 on the outer sleeve 8. At this point, the half-stroke gear 15 disengages from the first spur gear 18, preventing further rotation. As the half-stroke gear 15 continues to move, the rotating pipe 9 and the through hole 10 on the outer sleeve 8 remain connected during the delivery of the repair fluid, thereby delivering the repair fluid into the repair tank 1 and directly into the deep soil. This facilitates rapid mixing of the repair fluid and the soil. Furthermore, the rotation of the rotating shaft 19 will drive the third spur gear 25 to rotate, which in turn drives the second spur gear 24 to rotate, which in turn drives the connecting sleeve 23 to rotate, which in turn drives the connecting frame 21 to rotate, which in turn drives the stirring rod 22 to rotate. The rotating stirring rod 22 then stirs the soil in the repair tank 1, thereby accelerating the mixing efficiency of the repair fluid and the soil and improving the repair efficiency.

[0046] In this embodiment, during the soil remediation process, the drive component 20 runs in the forward direction, thus not driving the cleaning component 7. After the remediation fluid has finished remediating, the drive component 20 is reversed, and the cleaning component 7 runs, cleaning the outer surface of the stirring rod 22 and the inner wall of the remediation tank 1. During the reverse operation, the first flat gear 18 will reverse. At this time, due to the action of the torsion spring 16, the half-stroke gear 15 meshes with the first flat gear 18, thereby driving the half-stroke gear 15 and the rotating tube 9 to rotate in the reverse direction and reset. During the continuous reverse operation of the drive component 20, the half-stroke gear 15 will disengage from the first flat gear 18 again, thus preventing the rotating tube 9 from rotating continuously. As a result, the positions of the two sets of through holes 10 are staggered, so the remediation fluid will not continue to be delivered. The staggered positions of the two sets of through holes 10 prevent soil from entering and avoids blockage of the rotating tube 9. Furthermore, the filter cloth 11 further prevents soil from entering the rotating tube 9 and causing blockage.

[0047] Example 2

[0048] Please see Figures 7-9 Example 2 is described below. This embodiment further illustrates Example 1. The cleaning assembly 7 shown in the figure includes a cleaning plate 26 installed at the bottom of the connecting frame and sleeved on the outer surface of multiple sets of stirring rods 22. A rotating ring 27 is rotatably connected to the cleaning plate 26. A threaded rod 28 rotatably connected to the rotating ring 27 is threadedly connected to the rotating ring 27. A connecting shaft 29 extending to the top of the repair tank 1 and rotatably connected to the repair tank 1 is fixedly connected to the top of the threaded rod 28. The connecting shaft 29 is connected to the driving member 20 and has an elastic member 34 connected to its outer surface. A cleaning ring 31 that contacts the inner wall of the repair tank 1 is fixedly connected to the rotating ring 27. A rotating member 30 connected to the connecting shaft 29 is connected to the cleaning ring 31.

[0049] Please see Figures 7-9 The rotating component 30 shown in the figure includes a gear ring 32 fixedly connected to the cleaning ring 31. A fourth flat gear 33 is meshed on the inner side of the gear ring 32 and sleeved on the outer surface of the connecting shaft 29. The fourth flat gear 33 is movably connected to the threaded rod 28 and rotatably connected to the rotating ring 27. A limiting block 35 is fixedly connected to the fourth flat gear 33 and slidably connected to the connecting shaft 29 and the threaded rod 28. A limiting groove 36 adapted to the limiting block 35 is opened on the connecting shaft 29 and the threaded rod 28.

[0050] Please see Figure 7 and Figure 8 The elastic element 34 shown in the figure includes a movable piece 37 sleeved on the outer surface of the connecting shaft 29. One end of the movable piece 37 is fixedly connected to a spring 38 sleeved on the outer surface of the connecting shaft 29. One end of the spring 38 is fixedly connected to a fixed piece 39 fixedly connected to the connecting shaft 29. The movable piece 37 is located at the connection between the connecting shaft 29 and the threaded rod 28.

[0051] In this embodiment, when the drive component 20 is running, the connecting shaft 29 will rotate, thereby driving the threaded rod 28 to rotate. When the drive component 20 is running in the forward direction, the threaded rod 28 rotates in the forward direction, and the rotating ring 27 is located on the connecting shaft 29, squeezing the spring 38. Therefore, when the threaded rod 28 rotates in the forward direction, it will not drive the rotating ring 27 to move. After the soil remediation is completed, the drive component 20 runs in the reverse direction, thereby driving the connecting shaft 29 and the threaded rod 28 to rotate in the reverse direction. At this time, the spring 38 releases its elastic force, causing the rotating ring 27 to fit tightly with the threaded rod 28, thereby driving the rotating ring 27 to move, thereby driving the cleaning plate 26 to move, and thereby driving the cleaning ring 31 to move, thereby cleaning the outer surface of the stirring rod 22 and the inner wall of the remediation tank 1. During the rotation of the stirring rod 22, since the cleaning plate 26 and the rotating ring 27 are rotatably connected, the cleaning plate 26 and the rotating ring 27 continue to rotate during the remediation and cleaning process.

[0052] In this embodiment, when the connecting shaft 29 and the threaded rod 28 rotate, the limiting block 35 and the limiting groove 36 cause the fourth flat gear 33 to rotate, which in turn causes the gear ring 32 to rotate, which in turn causes the cleaning ring 31 to rotate. The rotating cleaning ring 31 improves the cleaning efficiency of the inner wall of the repair tank 1. Since the fourth flat gear 33 is rotatably connected to the rotating ring 27, the fourth flat gear 33 always moves with the rotating ring 27 and will not disengage from the gear ring 32.

[0053] Example 3

[0054] Please see Figure 2 and Figure 10 Example 3 is described below. This embodiment further describes Example 1. In the figure, the driving component 20 includes a support frame 40 fixed to the top of the repair tank 1. A drive motor 41 is fixedly connected to the support frame 40. A coupling 42 is fixedly connected to the output end of the drive motor 41. A drive shaft 43 fixedly connected to the connecting shaft 29 is fixedly connected to one end of the coupling 42. A transmission component 44 connected to the rotating shaft 19 is connected to the outer surface of the drive shaft 43.

[0055] Please see Figure 2 and Figure 10 The transmission component 44 shown in the figure includes a drive wheel 45 fixed to the outer surface of the drive shaft 43. A belt 46 is driven to the outer surface of the drive wheel 45. One end of the belt 46 is driven to a driven wheel 47 fixedly connected to the rotating shaft 19.

[0056] In this embodiment, by starting the drive motor 41, the coupling 42 will be driven to rotate, which in turn will drive the drive shaft 43 to rotate, which in turn will drive the connecting shaft 29 fixedly connected to it to rotate. When the drive shaft 43 rotates, it will also drive the drive wheel 45 to rotate, which in turn will drive the belt 46 to rotate, which in turn will drive the driven wheel 47 to rotate, which in turn will drive the rotating shaft 19 fixedly connected to it to rotate.

[0057] In this embodiment, the drive motor 41 is preferably model Y80M1-2. The power supply interface of the drive motor 41 is connected to the power supply system through a switch. The operating circuit of the drive motor 41 is a conventional motor forward and reverse rotation control program. The circuit operation is an existing conventional circuit. The circuits and controls involved in this solution are all existing technologies and will not be described in detail here.
