Description

Technical Field

[0001] This invention belongs to the field of manufacturing special equipment for environmental protection, and particularly relates to the field of soil remediation technology, specifically an organic soil remediation device. Background Technology

[0002] Organic pollution is a common type of soil pollution. Organic pollution mainly enters the soil through pesticide spraying, waste dumping, storage and leakage. Organic pollution soil remediation technologies are mainly divided into physical remediation, chemical remediation and bioremediation. Among them, chemical remediation is a commonly used soil remediation technology. In existing technologies, chemical remediation involves spraying chemical agent solutions onto the soil surface through nozzles. The chemical agents penetrate downwards into the soil. However, due to factors such as soil density, soil moisture content and ground depressions, the distribution of the chemical solution in the soil is uneven, and pollutants in some areas are not effectively removed, affecting the soil remediation effect. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an organic polluted soil remediation device in which chemical agent solution penetrates horizontally in the soil, so that the chemical agent solution penetrates evenly in all parts of the soil, thereby improving the remediation effect on organic polluted soil.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an organic polluted soil remediation device, comprising a support frame, a rotating shaft installed at the bottom of the support frame, a plurality of rotating circular blades installed at equal intervals on the rotating shaft, and a plurality of cutting edges provided at equal angles on the outer edge of the rotating circular blades.

[0005] Soil forming components are provided on both sides of the rotating circular cutter. The soil forming component includes a circular plate fixed on the rotating shaft, and the central axis of the circular plate is offset by a predetermined distance in the radial direction of the rotating shaft relative to the central axis of the rotating shaft. A collar is slidably sleeved on the outer periphery of the circular plate, and a pressure plate is installed at the bottom of the outer periphery of the collar.

[0006] The support frame drives the rotating circular blade and the circular plate to move in a horizontal direction perpendicular to the rotating shaft via a rotating shaft. The rotating shaft drives the rotating circular blade and the circular plate to rotate. The circular plate drives the pressure plate to move up and down via a collar. The cutting edge of the rotating circular blade cuts into the soil and cuts a groove in the soil. The cutting edge of the rotating circular blade throws the crushed soil in front of the direction in which the rotating circular blade moves. The pressure plate presses out a soil slope along both sides of the groove.

[0007] As a preferred embodiment of the present invention, an elastic rod is fixed at the bottom of the support frame corresponding to the position of each rotating circular blade, and an elastic strip is fixed on each elastic rod.

[0008] The elastic rod is located behind the rotating shaft in the direction of movement. The elastic rod is inserted into the groove cut by the rotating circular blade in the soil, and the elastic rod is in contact with the bottom side and inner wall of the groove.

[0009] As a preferred embodiment of the present invention, it further includes a housing, the inner cavity of which is connected to the inner cavity of the infusion tube, and the infusion tube is provided with an outlet tube corresponding to each position of the rotating circular blade, one end of which is connected to the inner cavity of the infusion tube, and the elastic strip is located between the outlet tube and the rotating circular blade.

[0010] As a preferred embodiment of the present invention, the elastic strip is made of elastic rubber or an elastic airbag.

[0011] As a preferred embodiment of the present invention, a blocking element is fixed on the support frame.

[0012] The blocking element is located in front of the rotating shaft in the direction of movement.

[0013] As a preferred embodiment of the present invention, the soil forming component further includes a limiting frame, the bottom end of which is fixedly connected to the top side of the pressure plate, and a fixed seat that slides along the length of the limiting frame is installed at the top of the limiting frame. The fixed seat is fixed on the support frame, and the bottom of the outer periphery of the collar is rotatably connected to the top side of the pressure plate.

[0014] As a preferred embodiment of the present invention, the support frame is equipped with a position-adjustable fixing frame.

[0015] The soil molding assembly also includes a limiting frame, the bottom end of which is fixedly connected to the top side of the pressure plate, and a fixed seat that slides along the length of the limiting frame is installed at the top of the limiting frame. The fixed seat is fixed on the fixed frame, and the bottom of the outer periphery of the collar is rotatably connected to the top side of the pressure plate.

[0016] As a preferred embodiment of the present invention, the end of the pressure plate facing the direction of movement of the support frame is tilted upward.

[0017] As a preferred embodiment of the present invention, the distance between the pressure plate and the rotating circular knife is 0.0cm-3.0cm.

[0018] As a preferred embodiment of the present invention, the thickness of the rotating circular blade is 1.0cm-3.0cm, and the distance between any two adjacent rotating circular blades is 3.0cm-15.0cm.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. The organic polluted soil remediation equipment of this invention, on the one hand, involves opening multiple trenches in the organic polluted soil and uniformly pressing soil slopes along both sides of the trenches. A chemical solution for remediating the organic polluted soil is injected into each trench. The liquid level of the chemical solution in the trench is located between the top side of the organic polluted soil and the top side of the soil slope. The chemical solution penetrates horizontally within the soil, ensuring uniform penetration throughout the soil and improving the remediation effect. On the other hand, elastic strips are attached to the bottom and inner walls of the trenches, enabling the injection of chemical solution during trenching and improving the remediation efficiency of this organic polluted soil remediation equipment. Furthermore, a blocking element causes a portion of the pulverized soil to fall onto the ground between two adjacent trenches. This portion of soil covers plant seeds. During the remediation process of the organic polluted soil, the chemical solution covers the plant seeds, allowing the plants to further remediate the organic polluted soil after the chemical solution treatment, thereby reducing the residual organic pollutants in the soil and improving the remediation effect.

[0020] 2. In the organic polluted soil remediation equipment of this invention, after the length of the groove opened in the soil reaches a set distance, the rotating circular cutter moves upward, and then moves forward 10.0cm-20.0cm, or moves between two adjacent grooves, and then moves downward. The cutting edge of the rotating circular cutter cuts a new groove in the soil, avoiding the accumulation of chemical reagent solution in low-lying areas due to ground inclination, thus improving the applicability of this organic polluted soil remediation equipment.

[0021] 3. In the organic polluted soil remediation equipment of the present invention, the bottom of the outer periphery of the collar and the top of the pressure plate are connected by a hinge or hinge seat. The end of the pressure plate facing the direction of movement of the support frame is tilted upward. The tilted end of the pressure plate knocks the excess soil on the slope off the slope, so as to thicken the soil covering the plant seeds and ensure the germination of the plant seeds.

[0022] 4. The organic contaminated soil remediation equipment of the present invention, on the one hand, the limiting frame and the fixed seat constrain the pressure plate, and the pressure plate can only move up and down relative to the rotating shaft, so that the thickness of the soil slope is uniform throughout, preventing the chemical agent solution in the trench from flowing out through the low-lying areas of the soil slope, and ensuring the remediation effect of the chemical agent solution on the organic contaminated soil; on the other hand, the end of the pressure plate facing the direction of movement of the support frame is tilted upward, and the tilted end of the pressure plate squeezes the uncompacted soil clods on the soil slope, causing the soil clods to break up, and preventing the soil clods from affecting the sealing effect of the soil slope on the chemical agent solution.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] Example 1: Please see Figures 1-6 This embodiment discloses an organic polluted soil remediation device, including a support frame 2. A rotating shaft 10 is mounted on the bottom of the support frame 2 via a bearing. Several rotating circular blades 7 are coaxially fixedly mounted on the rotating shaft 10 at equal intervals. Several cutting edges are provided at equal angles on the outer edge of the rotating circular blades 7.

[0027] Soil forming components are provided on both sides of the rotating circular blade 7. The soil forming components include a circular plate 12 fixed on the rotating shaft 10. The central axis of the circular plate 12 is offset from the central axis of the rotating shaft 10 by a predetermined distance in the radial direction of the rotating shaft 10. The predetermined distance is 1.0cm-5.0cm. A collar 13 is fitted on the outer periphery of the circular plate 12. The inner wall of the collar 13 and the outer periphery of the circular plate 12 are slidably fitted. The circular plate 12 can rotate within the collar 13. A pressure plate 11 is installed at the bottom of the outer periphery of the collar 13.

[0028] The support frame 2 is installed on an external traction vehicle. The external traction vehicle drives the rotating circular cutter 7 and the circular plate 12 to move in a horizontal direction perpendicular to the rotating shaft 10 through the support frame 2 and the rotating shaft 10. An external power device is installed on the support frame 2. The external power device drives the rotating circular cutter 7 and the circular plate 12 to rotate through the rotating shaft 10. The circular plate 12 drives the pressure plate 11 to move up and down through the collar 13. The cutting edge of the rotating circular cutter 7 cuts into the soil and cuts a groove in the soil. The rotating circular cutter 7 crushes the original soil in the groove. The cutting edge of the rotating circular cutter 7 throws the crushed soil in front of the direction of movement of the rotating circular cutter 7. The pressure plate 11 presses out a slope on both sides of the groove.

[0029] Furthermore, the support frame 2 is mounted on an external traction vehicle via a three-point connection suspension device commonly used in the prior art, and the external traction vehicle can control the lifting and lowering of the support frame 2 through the three-point connection suspension device.

[0030] Furthermore, the external power equipment includes a reversing gearbox, transmission rod, and pulley belt drive assembly mounted on the support frame 2. The power of the external traction vehicle is transmitted to the rotating shaft 10 through the reversing gearbox, transmission rod, and pulley belt drive assembly; or the external power equipment is a motor fixedly mounted on the support frame 2. The electrical energy of the external traction vehicle is supplied to the motor, and the power output shaft of the motor drives the rotating shaft 10 to rotate.

[0031] Furthermore, the horizontal distance between the rotating circular knife 7 and the pressure plate 11 is 0.0cm-3.0cm.

[0032] Furthermore, the thickness of the rotating circular blade 7 is 1.0cm-3.0cm, the distance between any two adjacent rotating circular blades 7 is 3.0cm-15.0cm, and the width of the pressure plate 11 is 1.0cm-3.0cm.

[0033] Furthermore, the number of rotating circular knives 7 on the rotating shaft 10 is no less than ten, and the cutting edge of the rotating circular knives 7 on the outer edge is no less than three.

[0034] The working process and principle of this embodiment are as follows: Workers install support frame 2 behind the external towing vehicle. The external power equipment drives the rotating circular cutter 7 and circular plate 12 to rotate via the rotating shaft 10. The external towing vehicle drives the rotating circular cutter 7 and circular plate 12 to move forward via support frame 2 and rotating shaft 10. Circular plate 12 drives pressure plate 11 to move up and down via collar 13, and pressure plate 11 is always located below circular plate 12. Workers cause support frame 2 to drive rotating circular cutter 7 to move down. The cutting edge of rotating circular cutter 7 cuts into the organic polluted soil. The cutting edge of rotating circular cutter 7 cuts a groove in the soil. The cutting edge of rotating circular cutter 7 throws the crushed soil in front of the direction of movement of rotating circular cutter 7. Crushed soil accumulates on both sides of rotating circular cutter 7. Pressure plate 11 squeezes the crushed soil near rotating circular cutter 7, causing the two sides of the groove to be pressed into a slope.

[0035] This organic contaminated soil remediation equipment involves creating multiple trenches in the organic contaminated soil and pressing out soil slopes along both sides of the trenches. Workers inject a chemical solution for remediating organic contaminated soil into each trench. The liquid level of the chemical solution in the trench is located between the top side of the organic contaminated soil and the top side of the soil slope. The chemical solution penetrates horizontally in the soil, ensuring uniform penetration throughout the soil.

[0036] Furthermore, the external traction vehicle is a tractor, so the potholes on the soil surface have little impact on the smooth driving of the tractor. The potholes on the soil surface also have little impact on the height of the trench along the top side of the slope. The height of the trench along the top side of the slope is consistent, which prevents the chemical solution in the trench from flowing out from the top side of the slope and improves the reliability of this organic polluted soil remediation equipment for the remediation of organic polluted soil.

[0037] Furthermore, the depth of the groove is 20.0cm-100.0cm.

[0038] Furthermore, in this embodiment, the direction in front is the direction of travel of the external traction vehicle.

[0039] Furthermore, the force required to push the rear end of the pressure plate 11 to rotate upward is greater than the force required to push the front end of the pressure plate 11 to rotate upward.

[0040] Example 2: like Figure 2 , Figure 3 and Figure 4 As shown, this embodiment discloses an organic polluted soil remediation device, whose structure is roughly the same as that of Embodiment 1. The difference is that in this embodiment, an elastic rod 5 is fixed at the bottom of the support frame 2 corresponding to the position of each rotating circular blade 7, and an elastic strip 4 is fixed on each elastic rod 5.

[0041] Among them, the elastic rod 5 is located behind the rotating shaft 10 in the direction of movement. The elastic rod 5 is inserted into the groove cut by the rotating circular knife 7 in the soil, and the elastic strip 4 is in contact with the bottom side and inner wall of the groove. The elastic strip 4 divides the groove into two parts in the horizontal direction.

[0042] Furthermore, the elastic strip 4 is an elastic rubber strip or an elastic airbag, and the elastic rod 5 is an elastic plastic rod, an elastic metal rod, or an elastic rubber rod.

[0043] The working process and principle of this embodiment are as follows: Workers add a chemical solution for remediating organically contaminated soil to an external container. They then uniformly inject the chemical solution into the groove behind the elastic strip 4. The liquid level of the chemical solution in the groove is higher than the top of the organically contaminated soil, but lower than the top of the slope. This allows for synchronous injection of the chemical solution during the trenching process, improving the remediation efficiency of the organically contaminated soil remediation equipment.

[0044] Furthermore, workers pre-piled soil at the initial formation point of the trench.

[0045] Example 3: like Figures 1-4 As shown, this embodiment discloses an organic polluted soil remediation device, whose structure is roughly the same as that of Embodiment 1. The difference is that this embodiment also includes a box 3, and an elastic rod 5 is fixed at the bottom of the support frame 2 corresponding to the position of each rotating circular blade 7, and an elastic strip 4 is fixed on each elastic rod 5.

[0046] The inner cavity of the box 3 is connected to the inner cavity of the infusion tube 8. The infusion tube 8 is provided with an outlet tube 6 corresponding to each position of the rotating circular knife 7. One end of the outlet tube 6 is connected to the inner cavity of the infusion tube 8. The elastic strip 4 is located between the outlet tube 6 and the rotating circular knife 7.

[0047] Among them, the elastic rod 5 is located behind the rotating shaft 10 in the direction of movement. The elastic rod 5 is inserted into the groove cut by the rotating circular knife 7 in the soil, and the elastic strip 4 is in contact with the bottom side and inner wall of the groove. The elastic strip 4 divides the groove into two parts in the horizontal direction.

[0048] Furthermore, the elastic strip 4 is an elastic rubber strip or an elastic airbag, and the elastic rod 5 is an elastic plastic rod, an elastic metal rod, or an elastic rubber rod.

[0049] The working process and principle of this embodiment are as follows: Workers add a chemical solution for remediating organically contaminated soil into the tank 3. The chemical solution in the tank 3 flows into the groove behind the elastic strip 4 through the infusion pipe 8 and the outlet pipe 6. The liquid level of the chemical solution in the groove is higher than the top side of the organically contaminated soil, and lower than the top side of the soil slope. This allows for the injection of chemical solution during the groove opening process, improving the remediation efficiency of the organically contaminated soil remediation equipment.

[0050] Furthermore, the box body 3 is fixed to an external traction vehicle or support frame 2.

[0051] Furthermore, when the length of the groove opened in the soil by the rotating circular cutter 7 reaches 20.0m-50.0m, the operator moves the rotating circular cutter 7 upward, causing it to detach from the soil. An external traction vehicle then moves the rotating circular cutter 7 forward by 10.0cm-20.0cm, or moves it between two adjacent grooves. Then, the rotating circular cutter 7 moves downward, and its cutting edge cuts a new groove in the soil. This solves the problem of chemical solutions accumulating in low-lying areas due to ground inclination, thus improving the applicability of this organic polluted soil remediation equipment.

[0052] Furthermore, a control valve is installed on the infusion tube 8 and / or the outlet tube 6.

[0053] Furthermore, workers pre-piled soil at the initial formation point of the trench.

[0054] Example 4: like Figure 1 and Figure 3 As shown, this embodiment discloses an organic polluted soil remediation device, whose structure is roughly the same as that of Embodiment 1. The difference is that in this embodiment, a blocking component 1 is fixed on the support frame 2. The blocking component 1 is a blocking plate or a blocking cloth.

[0055] Among them, the blocking component 1 is located in front of the moving direction of the rotating shaft 10.

[0056] The working process and principle of this embodiment are as follows: Workers pre-sow plant seeds capable of remediating organically polluted soil on the surface of the soil manually or using seeding machinery. The plants that grow from the seeds absorb organic pollutants from the soil through their roots, or the plant roots improve the soil's micro-ecological environment, thereby promoting the decomposition of organic pollutants.

[0057] The rotating circular blade 7 throws the pulverized soil in a fan shape toward the blocking component 1. The blocking component 1 causes a portion of the pulverized soil to fall onto the ground between two adjacent slots. This portion of soil covers the plant seeds. During the remediation of organically contaminated soil by chemical agent solution, the plant seeds are covered with soil. After the organically contaminated soil is remediated by chemical agent solution, the plants further remediate the organically contaminated soil, further reducing the residue of organic pollutants in the soil and improving the remediation effect of organically contaminated soil.

[0058] Furthermore, the plant seeds are oat seeds, alfalfa seeds, tall fescue seeds, sunflower seeds, or clover seeds.

[0059] Furthermore, the bottom of the outer periphery of the collar 13 and the top of the pressure plate 11 are connected by a hinge or hinge seat. The end of the pressure plate 11 facing the direction of movement of the support frame 2 is tilted upward. During the vertical plane movement of the collar 13, the pressure plate 11 has a horizontal reciprocating movement. The tilted end of the pressure plate 11 knocks the excess soil on the slope off the slope, thickening the soil covering the plant seeds and ensuring the germination of the plant seeds.

[0060] Furthermore, the staff can adjust the thickness of the crushed soil on the ground between two adjacent slots by adjusting the rotation speed of the rotating shaft 10 or adjusting the distance between the blocking part 1 and the rotating circular cutter 7.

[0061] Example 5:

[0062] like Figure 3 , Figure 5 and Figure 6 As shown, this embodiment discloses an organic polluted soil remediation device, whose structure is roughly the same as that of Embodiment 1. The difference is that the soil molding component in this embodiment also includes a limiting frame 14. The bottom end of the limiting frame 14 is fixedly connected to the top side of the pressure plate 11. The top end of the limiting frame 14 is equipped with a fixed seat 15 that slides along the length direction of the limiting frame 14. The fixed seat 15 is fixed to the support frame 2 by bolts or buckles. The bottom of the outer periphery of the collar 13 and the top side of the pressure plate 11 are connected by a hinge or hinge seat.

[0063] The working process and principle of this embodiment are as follows: The limiting frame 14 and the fixed seat 15 constrain the pressure plate 11. The pressure plate 11 can only move up and down relative to the rotating shaft 10, so that the thickness of the soil slope is consistent throughout, preventing the chemical solution in the trench from flowing out through the low-lying areas of the soil slope, and ensuring the remediation effect of the chemical solution on the organically contaminated soil.

[0064] Furthermore, the fixed base 15 is a sleeve, the limiting frame 14 is a straight rod, the sleeve is slidably sleeved on the straight rod, and the bottom end of the straight rod is fixedly connected to the top side of the pressure plate 11.

[0065] Furthermore, the end of the pressure plate 11 facing the direction of movement of the support frame 2 is tilted upwards. The tilted end of the pressure plate 11 squeezes the uncompacted soil clods on the slope, breaking the soil clods and preventing them from affecting the sealing effect of the chemical solution on the slope.

[0066] Example 6: like Figures 3-6 As shown, this embodiment discloses an organic polluted soil remediation device, whose structure is roughly the same as that of Embodiment 1. The difference is that in this embodiment, a fixing frame 9 is installed on the support frame 2 by bolts, buckles or adhesive. The soil forming component also includes a limiting frame 14. The bottom end of the limiting frame 14 is fixedly connected to the top side of the pressure plate 11. A fixing seat 15 that slides along the length direction of the limiting frame 14 is installed on the top end of the limiting frame 14. The fixing seat 15 is fixed on the fixing frame 9. The bottom of the outer periphery of the collar 13 and the top side of the pressure plate 11 are connected by a hinge or hinge seat.

[0067] Furthermore, the end of the pressure plate 11 facing the direction of movement of the support frame 2 is tilted upward.

[0068] The working process and principle of this embodiment are as follows: The limiting frame 14 and the fixed seat 15 constrain the pressure plate 11. The pressure plate 11 can only move up and down relative to the rotating shaft 10, so that the thickness of the soil slope is consistent throughout, preventing the chemical solution in the trench from flowing out through the low-lying areas of the soil slope, and ensuring the remediation effect of the chemical solution on the organically contaminated soil.

[0069] The staff adjusts the position of the fixing frame 9 on the support frame 2 along a horizontal direction perpendicular to the rotating shaft 10, thereby adjusting the distance between the pressure plate 11 and the collar 13, making it easier to adjust the thickness of the soil slope and improving the applicability of this organic polluted soil remediation equipment.

[0070] Furthermore, the end of the pressure plate 11 facing the direction of movement of the support frame 2 is tilted upwards. The tilted end of the pressure plate 11 squeezes the soil clods on the slope, breaking them up and preventing them from affecting the sealing effect of the chemical solution on the slope.

[0071] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
