Description

Technical Field

[0001] The present invention relates to the technical field of ecological soil restoration, and in particular to a mine soil restoration system and process based on landscape optimization. Background Art

[0002] With the gradual depletion of coal resources and the closure of some old mines, a large number of abandoned mines have been left behind; coal mining activities have destroyed surface vegetation, leading to geological environmental problems such as ground collapse and groundwater pollution; in some areas, abandoned mines have begun to be ecologically restored and reused, such as converted into tourist attractions, parks or reservoirs, and governments and enterprises are also investing in the development of new technologies and methods to repair mines more efficiently and at a lower cost. The present invention aims to provide a method that can be moved in a mine and can break up the soil to repair the soil more effectively, and a method for repairing contaminated soil in a mine.

[0003] Soil remediation includes physical stabilization and chemical remediation. The former ensures the physical stability of the soil through earthwork measures such as landfill, land leveling, slope adjustment, etc. The latter uses soil replacement, adding neutralizers or utilizing plant remediation technology to reduce toxic and acidic substances in the soil. In general, physical remediation, chemical remediation, or both physical and chemical remediation can be chosen according to the actual situation of the soil.

[0004] In order to make a more accurate comparison, for example, Chinese patent publication number CN112742857A discloses a soil remediation device that can enhance the soil remediation effect;

[0005] It includes a bracket, a crushing box is correspondingly arranged on the inner side of the bracket, a crushing roller is correspondingly arranged inside the crushing box, a transmission gear is arranged on the front of the crushing box and at the position corresponding to the crushing roller, a discharge port is arranged at the bottom of the crushing box, a subdivision bucket is correspondingly arranged on the inner side of the bracket and below the crushing box, a vibration motor is correspondingly arranged on the outer side of the subdivision bucket, a mounting frame is correspondingly arranged on the outer side of the subdivision bucket, a spring is arranged at the bottom of the mounting frame, a conveying box is correspondingly arranged on the inner side of the bracket and below the subdivision bucket, and a box door is connected to the front of the conveying box through a hinge.

[0006] However, when using the above-mentioned existing technologies to repair soil, there are still the following problems:

[0007] 1. Although the soil remediation device can break the soil into particles when remediating the soil, it can only physically remediate the soil without the support of any auxiliary equipment. Therefore, the remediation method is relatively simple. If the soil is to be chemically remediated, it is necessary to manually add chemical agents into the device, and the device can only be fixed in one place. That is, when soil remediation is required, the contaminated soil needs to be manually transported to the device and then remediated. After the remediation is completed, it is taken out of the device and transported back to the laying site. The remediation process is relatively cumbersome.

[0008] 2. The above-mentioned soil remediation device cannot remove moisture from soil containing moisture inside. That is, when the above-mentioned device is used to repair some moist soil, it is necessary to manually remove the moisture from the soil before repairing the soil, which further reduces its efficiency in soil remediation. Therefore, the applicability of the above-mentioned soil remediation device is relatively low.

[0009] Therefore, based on the above-stated viewpoint, there is still room for optimization in the existing technology for soil remediation. Summary of the invention

[0043] The following is combined with Figure 1 To Attachment Fig.12 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0044] The embodiment of the present application discloses a mine soil remediation system and process based on landscape optimization, which explains that the mine soil remediation system and process based on landscape optimization are mainly used in the process of repairing soil in a mine. In terms of technical effect, the present invention can be moved in a mine and repair the soil in the mine anytime and anywhere; in particular, the present invention can also chemically repair the soil by injecting chemicals, or physically repair the soil by heating, and can also perform simultaneous chemical or physical repair of the soil to cope with different types of soil, thereby increasing the applicability of the present invention; and, the present invention can also crush the soil before performing soil remediation to facilitate a more thorough repair of the soil later.

[0045] Example 1: Reference Figure 1 and Figure 2 As shown, it includes a main body 1, a support shaft 10, a wheel 11, a conveying shaft 12 and a crushing unit 2. The left and right sides of the main body 1 are rotatably provided with support shafts 10 that are symmetrically distributed front and back. The end of the support shaft 10 away from the main body 1 is provided with wheels 11. The main body 1 can move in the mine through the support shaft 10 and the wheels 11; the front and rear inner walls of the main body 1 are jointly rotatably provided with conveying shafts 12 that are symmetrically distributed left and right. The conveying shaft 12 is provided with a crushing unit 2 for crushing the soil. The conveying shaft 12 can rotate under the limit of the front and rear inner walls of the main body 1 to indirectly drive the crushing unit 2 to operate.

[0046] Continue to refer to Figure 2 As shown, the crushing unit 2 is used to crush the soil; specifically, the crushing unit 2 includes a feed trough 20, a conveyor belt 21, a driven bar 22, a rotating shaft 23, a long gear 24, a protective soft plate 25, a water filter trough 26, a water guide plate 27 and a drainage trough 28. The feed trough 20 is opened at the right end of the main body 1, and a conveyor belt 21 is arranged between two symmetrical conveying shafts 12. The soil can enter the main body 1 from the feed trough 20 and then fall onto the conveyor belt 21. When the conveying shaft 12 rotates, it can drive the conveyor belt 21 to move toward the middle of the main body 1, so that the conveyor belt 21 can drive the soil to move to the middle of the main body 1; a plurality of driven bars 22 evenly distributed along the extension section of the conveyor belt 21 are arranged on the outside of the conveyor belt 21, and a rotating shaft 23 is arranged on the front and rear inner walls of the main body 1 for common rotation. One end of the rotating shaft 23 passes through the outer wall of the main body 1, and the end of the rotating shaft 23 located outside the main body 1 can be connected to the external drive motor 810, and it is driven to rotate by the external drive motor 810.

[0047] A long gear 24 is sleeved on the outer side of the rotating shaft 23. When the rotating shaft 23 rotates, it can drive the long gear 24 to rotate synchronously; and the teeth of the long gear 24 are staggered with the corresponding driven bar 22. Protective soft plates 25 are also provided at the front and rear ends of the conveyor belt 21. When the long gear 24 is driven to rotate, it can contact the driven bar 22 through its outer teeth, so that the driven bar 22 can drive the conveyor belt 21 to move around the conveying shaft 12. After the large pieces of soil are driven by the conveyor belt 21 to contact the long gear 24, they will be broken up by the relative force between the teeth of the corresponding long gear 24 and the driven bar 22. The protective soft plate 25 will keep synchronous movement with the conveyor belt 21, and the protective soft plate 25 can prevent the broken soil from escaping from the conveyor belt 21.

[0048] The conveyor belt 21 is also provided with several water filtering grooves 26 evenly distributed along its extended section. The front and rear inner walls of the main body 1 are also provided with water guide plates 27. The lower end of the main body 1 is provided with a drainage groove 28 corresponding to the lower end of the water guide plate 27. After the soil with residual moisture inside is broken up, the water inside the soil will flow out due to the squeezing between the long gear 24 and the conveyor belt 21, and finally flow down from the drainage groove 28 and fall on the water guide plate 27, and then flow out from the drainage groove 28 along the guide plate to the outside of the main body 1.

[0049] Reference Figures 3 to 6 As shown, the front and rear inner walls of the main body 1 are also rotatably provided with a drive shaft 30, and a repair unit 3 for repairing the soil is arranged between the drive shafts 30; specifically, the repair unit 3 includes a drive shaft 30, a drive plate 31, a drive ring 32, a chemical barrel 33, a physical barrel 34, a sleeve barrel 35, an annular cavity 36, an inlet and outlet groove 37, a circular groove 38, a one-way valve 39, a connecting groove 310, an arc-shaped discharge groove 311, an arc-shaped electric push plate 312, a resistance groove 313, an arc-shaped sealing plate 314, a reset push spring 315 and a driven bevel block 316, and the drive plate 31 is arranged at the opposite ends of the two drive shafts 30, and the drive shaft 30 can drive the corresponding drive plate 31 to rotate around its axis.

[0050] The opposite ends of the front and rear corresponding driving plates 31 are rotatably provided with driving rings 32, and the upper and lower corresponding driving rings 32 are connected by belt transmission, that is, the upper and lower corresponding driving rings 32 can be synchronously rotated by belt transmission, and the chemical barrels 33 and physical barrels 34 distributed upper and lower are respectively arranged between the two groups of front and rear corresponding driving rings 32. The driving ring 32 can rotate on the driving plate 31, and the driving ring 32 can also drive the corresponding chemical barrel 33 and physical barrel 34 to rotate synchronously when rotating. At the same time, the driving plate 31 can also drive the chemical barrel 33 and the physical barrel 34 to rotate around their axis in the main body 1 through the driving ring 32.

[0051] The outer sides of the chemical barrel 33 and the physical barrel 34 are both rotatably provided with a sleeve barrel 35 with a U-shaped inner wall, and an annular cavity 36 is formed between the sleeve barrel 35 and the corresponding chemical barrel 33 or physical barrel 34. The chemical barrel 33 and the physical barrel 34 and the corresponding sleeve barrel 35 are both provided with mutually connected inlet and outlet grooves 37 on the outer sides. The sleeve barrel 35 can be rotated on the corresponding chemical barrel 33 or physical barrel 34, and the soil can enter the corresponding chemical barrel 33 or physical barrel 34 through the inlet and outlet grooves 37 on the sleeve barrel 35 and the inlet and outlet grooves 37 on the chemical barrel 33 or the inlet and outlet grooves 37 on the physical barrel 34.

[0052] The outside of the chemical barrel 33 and the physical barrel 34 is also provided with several circular grooves 38 with evenly distributed extension sections, and a one-way valve 39 is arranged in the circular groove 38. A connecting groove 310 is arranged on the left side of the sleeve barrel 35. The one-way valves 39 on the outside of the chemical barrel 33 and the physical barrel 34 are respectively from outside to inside and from inside to outside. The chemical agent can enter the annular cavity 36 between the corresponding chemical barrels 33 through the connecting groove 310 on the outside of the corresponding sleeve barrel 35. Then, the water pressure of the chemical agent is increased, and the chemical agent will enter the chemical barrel 33 through the one-way valve 39 on the outside of the chemical barrel 33, and enter the soil in the chemical barrel 33 for chemical remediation, and the chemical agent entering the chemical barrel 33 will no longer flow out from the corresponding one-way valve 39.

[0053] The present invention physically repairs the soil by heating, so the moisture or chemical agents inside the soil may evaporate during the heating process, so the evaporated gas can flow out from the corresponding one-way valve 39, flow into the corresponding annular cavity 36, and finally flow out from the corresponding connecting groove 310; the lower end of the main body 1 is also provided with an arc-shaped discharge groove 311 corresponding to the inlet and outlet groove 37, and an arc-shaped electric push plate 312 is provided on the inner wall of the inlet and outlet groove 37, and the telescopic end of the arc-shaped electric push plate 312 blocks the inlet and outlet groove 37.

[0054] When the soil no longer needs to be repaired, the corresponding chemical barrel 33 or physical barrel 34 can be driven to rotate through the drive ring 32, so that the inlet and outlet grooves 37 on the outside thereof correspond to the arc-shaped discharge groove 311, and the telescopic end of the arc-shaped electric push plate 312 is retracted, and the inlet and outlet grooves 37 are no longer blocked, so that the soil inside the chemical barrel 33 or physical barrel 34 is discharged from the arc-shaped discharge groove 311 to the outside of the main body 1. If the chemical barrel 33 or physical barrel 34 that needs to be discharged is located at the upper end inside the main body, at this time, it is only necessary to indirectly drive the chemical barrel 33 or physical barrel 34 to rotate through the drive shaft 30, and then rotate the barrel body again. Similarly, by controlling the chemical barrel 33 or physical barrel 34 to be located at the upper part of the main body, the soil can be controlled to enter the corresponding chemical barrel 33 or physical barrel 34.

[0055] A resistance groove 313 is also provided at the left end of the sleeve barrel 35, and one end of the resistance groove 313 is connected with the corresponding connecting groove 310, and an arc-shaped sealing plate 314 is slidingly provided in the resistance groove 313 and the connecting groove 310, and the arc-shaped sealing plate 314 can slide in the resistance groove 313 and the connecting groove 310; a return push spring 315 is provided between the arc-shaped sealing plate 314 and the inner wall of the resistance groove 313, and the return push spring 315 can give a driving force to the arc-shaped sealing plate 314 in the initial state, so that the arc-shaped sealing plate 314 can block the connecting groove 310; a driven inclined block 316 located in the resistance groove 313 is provided on the outer side of the arc-shaped sealing plate 314, and the arc-shaped sealing plate 314 can be moved by the driven inclined block 316 through external force, and no longer blocks the connecting groove 310.

[0056] Reference Figure 7 As shown, the front and rear inner walls of the main body 1 are also provided with a sealing component 4 for covering the joints between the chemical barrel 33 and the physical barrel 34 to prevent leakage during feeding or discharging; specifically, the sealing component 4 includes a V-shaped frame plate 40 and a sealing plate 41, the V-shaped frame plate 40 is arranged on the front and rear inner walls of the main body 1, and the upper and lower ends of the V-shaped frame plate 40 respectively correspond to the left end of the conveyor belt 21 and the inlet and outlet groove 37 on the outside of the chemical barrel 33, the crushing unit 2 crushes the soil and drives the crushed soil to move to the left side of the conveyor belt 21, and then the soil will fall from the conveyor belt 21 and fall on the V-shaped frame plate 40, and then the soil will fall along the V-shaped frame plate 40 through the inlet and outlet groove 37 into the corresponding chemical barrel 33 or physical barrel 34.

[0057] A sealing plate 41 is provided in the middle of the front and rear corresponding driving plates 31, and the upper ends of the sealing plates 41 correspond to the corresponding chemical barrels 33 and physical barrels 34 respectively. The sealing plate 41 is used to seal the space between the chemical barrel 33 and the physical barrel 34. If the soil in the chemical barrel 33 is to be poured into the physical barrel 34, the chemical barrel 33 and the physical barrel 34 are both rotated at this time, so that the inlet and outlet grooves 37 on the outside of both sides correspond to each other, and then the arc-shaped electric push plate 312 on the inner wall of the inlet and outlet groove 37 is no longer blocked, so that the soil in the chemical barrel 33 can be discharged from the corresponding inlet and outlet groove 37, and then enter the physical barrel 34 from the inlet and outlet groove 37 on the outside of the physical barrel 34. The sealing plate 41 is used to prevent the soil from splashing out during this process.

[0058] Continue to refer to Figure 5As shown, a repair component 5 is also provided between the driving plates 31 for enabling the chemical barrel 33 and the physical barrel 34 to play a repair role; specifically, the repair component 5 includes a fixed shaft 50, a blade 51 and a spiral slice 52, and the fixed shaft 50 is symmetrically arranged between the front and rear corresponding driving plates 31 and passes through the corresponding chemical barrel 33 and physical barrel 34 at both ends respectively, and a plurality of fixed rings evenly distributed along the extension section thereof are provided on the outside of the fixed shaft 50 located inside the chemical barrel 33, and a plurality of blades 51 are provided on the outside of the fixed ring. When the soil is chemically repaired in the chemical barrel 33, the chemical barrel 33 can be rotated so that the soil inside it is also rolled and connected with the blade 51, and the soil is separated again, so that the chemical agent can completely penetrate into the soil.

[0059] A spiral slice 52 is arranged on the outside of the fixed axis 50 inside the physical barrel 34, and a heating plate is arranged inside the spiral slice 52. Similarly, the physical barrel 34 can also rotate when physically repairing the soil, so that the soil inside it contacts the spiral slice 52. The heating plate inside the spiral slice 52 will heat the spiral slice 52, and the spiral slice 52 will transfer the heat to the soil, so that the soil can be heated more thoroughly.

[0060] Example 2: Reference Figure 8 and Fig. 9 As shown, on the basis of Example 1, in order to be able to transport chemical repair liquid toward the inside of the chemical barrel 33 and to extract the gas generated by heating the inside of the physical barrel 34 from the physical barrel 34, a propulsion unit 6 is provided inside the main body 1; specifically, the propulsion unit 6 includes a limit groove 60, a push plate 61, a mounting block 62, an arc frame plate 63, a connecting groove 64, an active inclined block 65, a storage box 66, an air pump 67, a connecting pipe 68 and a driving cylinder 69, the limit groove 60 is provided on the upper and lower inner walls of the main body 1, and a push plate 61 is slidably provided in the upper and lower corresponding limit grooves 60, and a mounting block 62 symmetrically distributed up and down is provided at the left end of the push plate 61, and the push plate 61 can drive the mounting block 62 to move left and right in the main body 1 under the limit guide of the limit groove 60.

The pushing plate 61 can indirectly drive the active inclined block 65 to move toward the driven inclined block 316. When the active inclined block 65 contacts the driven inclined block 316, the active inclined block 65 can resist the driven inclined block 316, so that the driven inclined block 316 can drive its corresponding arc-shaped sealing plate 314 to no longer block the connecting groove 310. At this time, the connecting groove 64 on the arc-shaped frame plate 63 will be connected with the corresponding connecting groove 310, so as to realize the connection between the connecting groove 64 and the connecting groove 310.

[0062] A storage box 66 and an air pump 67 are also provided at the upper end of the main body 1.

The upper and lower corresponding telescopic ends of the spring telescopic plates 70 are also provided with upper and lower symmetrical resistance blocks 71. The front and rear inner walls of the connecting groove 310 are also provided with triangular plates 72 corresponding to the resistance blocks 71. When the arc frame plate 63 contacts the corresponding chemical barrel 33 and physical barrel 34, the resistance block 71 will contact the triangular plate 72, so that the resistance block 71 will drive the corresponding telescopic end of the spring telescopic plate 70 to shrink, so that the connecting groove 64 is no longer blocked.

[0065] Example 3: Reference Fig.11 and Fig.12 As shown, on the basis of Example 1 and Example 2, in order to drive the repair unit 3 to operate, a driving unit 8 is provided; specifically, the driving unit 8 includes a transmission shaft 1 80, a transmission shaft 2 81, a transmission gear 1 82, a transmission gear 2 83, a driving gear 84, a transmission shaft 3 85, a transmission gear 3 86, a sliding groove 87, a support plate 88, a guide curved groove 89, a driving motor 810 and a linkage gear 811, the transmission shaft 1 80 and the transmission shaft 2 81 are rotatably arranged on the inner wall of the main body 1, the transmission shaft 1 80 and the transmission shaft 2 81 are connected by a belt drive, and the transmission shaft 1 80 and the transmission shaft 2 81 can be synchronously rotated on the inner wall of the main body 1 through the belt drive; the transmission gear 1 82 and the transmission gear 2 83 are respectively sleeved on the outer surfaces of the transmission shaft 1 80 and the transmission shaft 2 81, and the transmission shaft 1 80 and the transmission shaft 2 81 can drive the corresponding transmission gear 1 82 and the transmission gear 2 83 to rotate synchronously when rotating.

[0066] A driving gear 84 meshing with a second transmission gear 83 is sleeved on the outer side of the driving ring 32 on one side, and the driving gear 84 can drive the corresponding driving ring 32 to rotate, so that the driving ring 32 can drive the corresponding chemical barrel 33 or physical barrel 34 to rotate; a transmission shaft 3 85 is also rotatably arranged on the inner wall of the main body 1, and a transmission gear 3 86 is sleeved on the outer side of the transmission shaft 3 85, and the transmission shaft 3 85 is connected to the driving shaft 30 through a belt drive, and the transmission gear 3 86 can drive the transmission shaft 3 85 to rotate on the inner wall of the main body 1, and the transmission shaft 3 85 can drive the corresponding driving shaft 30 to rotate through the belt drive, so as to drive the repair unit 3 to rotate as a whole.

[0067] A sliding groove 87 is provided at one end of the push plate 61, and a support plate 88 is slidably arranged in the sliding groove 87. A guide bend groove 89 is provided on the inner wall of the main body 1, and the end of the support plate 88 away from the sliding groove 87 is located in the guide bend groove 89. A driving motor 810 is provided on the right side of the support plate 88 through a motor seat, and a linkage gear 811 corresponding to the transmission gear three 86 and the transmission gear one 82 is sleeved on the main shaft of the driving motor 810. When the push plate 61 moves, it can drive the support plate 88 to move synchronously, and when the support plate 88 is driven, it can move up and down on the push plate 61 along the guide bend groove 89, and drive the driving motor 810 to move up and down through the motor seat.

[0068] The driving motor 810 can drive the linkage gear 811 to rotate. In the initial state, the pushing plate 61 indirectly pushes the driving cylinder 69 to move toward the right side of the main body 1, so that the linkage gear 811 can mesh with the corresponding transmission gear three 86. At this time, the driving cylinder 69 can indirectly drive the transmission gear three 86 to rotate. If the driving cylinder 69 continues to push the pushing plate 61 to move, in order to avoid the linkage gear 811 and the transmission gear three 86 from displacing contact so that the transmission gear three 86 is driven to rotate, the support plate 88 will move upward under the limit of the guide bend groove 89, so that the linkage gear 811 disengages from the transmission gear three 86, and then the pushing plate 61 indirectly drives the linkage gear 811 to mesh with the left side of the transmission gear one 82. At this time, the linkage gear 811 can drive the transmission gear one 82 to rotate.

The feeding cone frame 90 is used when the device is moved in the mine, and the construction personnel can shovel the soil into the feeding cone frame 90, and the soil then enters the main body 1 from the feeding cone frame 90 to prevent the soil from being spilled during feeding.

[0070] In addition, the present invention also provides a mine soil remediation process based on landscape optimization, comprising the following steps:

[0071] S1: Soil crushing. The contaminated soil enters the crushing unit 2 through the feed trough 20. The crushing unit 2 crushes the large pieces of soil and removes part of the moisture in the soil during the crushing process.

[0072] S2: Chemical remediation. The crushed soil falls onto the remediation unit 3. The remediation unit 3 performs chemical remediation on the soil by adding chemical agents to remove or neutralize pollutants in the soil.

[0073] S3: Physical remediation. The remediation unit 3 performs physical remediation on the soil by heating to volatilize organic matter and water in the soil and reduce the concentration of residual pollutants in the soil.

[0074] S4: Chemical and physical remediation. If chemical and physical remediation are required, the remediation unit 3 performs chemical remediation on the soil and then performs physical remediation on the soil, and vice versa, so that the pollutants in the soil are completely removed.
