Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and in particular to a soil remediation device for environmental governance. Background Technology

[0002] Soil remediation is a technical measure to restore contaminated soil to its normal function. It utilizes physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in the soil, reducing their concentration to acceptable levels or converting toxic and harmful pollutants into harmless substances. Fundamentally, the technical principles of contaminated soil remediation can be categorized into two types: first, altering the form in which pollutants exist in the soil or how they bind to the soil, reducing their mobility and bioavailability in the environment; and second, reducing the concentration of harmful substances in the soil.

[0003] In related technologies, one can refer to Chinese utility model patent with authorization announcement number CN222790154U, which discloses a soil remediation agent spraying device, including a base, a reagent tank, and wheels. The reagent tank is equipped with a stirring component. It is a multi-functional spraying structure composed of a hollow box, a transition pipe, an electric push rod, a spray pipe, two branch valve pipes, and several nozzles. After the two multi-functional spraying structures are combined with a water pump, two infusion pipes, and two elastic spiral pipes to form a double infusion structure, two spray pipes can be extended to spray the contaminated soil.

[0004] However, due to soil clumping or clumping, the remediation agents in this method can only be sprayed on the soil surface and cannot fully contact and mix with the internal soil, thus reducing the efficiency of soil remediation. Utility Model Content

[0005] In order to improve the efficiency of soil remediation, this utility model provides a soil remediation device for environmental governance.

[0006] This application provides a soil remediation device for environmental governance, which adopts the following technical solution:

[0007] A soil remediation device for environmental governance includes a mobile frame, a reagent tank, a soil breaking component, and a spraying component. The mobile frame is equipped with wheels. The reagent tank is used to temporarily store soil remediation liquid. The soil breaking component is mounted on the mobile frame and is used to break up the soil. The spraying component is mounted on the mobile frame and connected to the reagent tank and is used to spray the remediation liquid onto the broken soil.

[0008] By adopting the above technical solution, the mobile frame moves to the repair point via the moving wheels. The soil breaking component is activated to break up the soil, making it loose. Then, the spraying component sprays the repair liquid onto the soil. Since the soil has become loose, the penetration efficiency of the repair liquid will be improved, thereby improving the efficiency of soil repair.

[0009] Optionally, the ground-breaking component includes:

[0010] A rotating shaft is rotatably mounted inside a movable frame, and the extending direction of the rotating shaft is perpendicular to the moving direction of the movable frame.

[0011] The tillage blades are provided in multiple locations, which are spaced apart on the rotating shaft along the axis of rotation. The tillage blades extend outward and are used to break the soil.

[0012] A drive motor is mounted on a movable frame and its output end is connected to a rotating shaft for transmission.

[0013] By adopting the above technical solution, the drive motor starts and drives the rotating shaft to rotate, which in turn drives multiple tillage blades to rotate, thereby breaking up the soil and making it loose, which facilitates the penetration of subsequent remediation liquid.

[0014] Optionally, the spray assembly includes:

[0015] The first spray pipe is mounted on a mobile frame and located below the pesticide tank and behind the tiller. The first spray pipe is equipped with multiple vertically downward-extending first nozzles. The pesticide tank is equipped with a first spray pump connected to the first spray pipe. The mobile frame is equipped with a lifting device that drives the first spray pipe to rise and fall. During spraying, the first nozzles are inserted into the soil.

[0016] The second spray pipe is mounted on a movable frame and located on the side of the pesticide tank away from the tillage blade. The second spray pipe is equipped with multiple atomizing nozzles located above the soil. The pesticide tank is equipped with a second spray pump connected to the second spray pipe.

[0017] By adopting the above technical solution, after the soil is broken up, the lifting component drives the first spray pipe to descend until the first nozzle is inserted into the soil. The loose state of the soil increases the ease of insertion of the first nozzle. The first spray pump starts, and the remediation liquid in the agent tank is sprayed out from the first nozzle after passing through the first spray pipe, thereby increasing the penetration height of the remediation liquid and thus increasing the depth of soil remediation. As the moving wheels move, the first spray pipe moves synchronously, and the soil is gradually moved out of the moving frame. The second spray pump starts to draw the remediation liquid into the second spray pipe and spray it out through the atomizing nozzle, thereby spraying the remediation liquid on the soil surface. The loose state of the soil increases the penetration efficiency of the remediation liquid. The first and second spray pipes work together to improve the use effect of the remediation liquid. They can spray the soil interior to increase the penetration height of the remediation liquid, and also spray the surface soil to enhance the effect of the remediation liquid, thereby improving the efficiency of soil remediation.

[0018] Optionally, the output end of the first spray pump is connected to the first spray pipe via a connecting hose, and both ends of the first spray pipe are fixed with connecting plates, and the lifting component drives the connecting plates to rise and fall.

[0019] By adopting the above technical solution, the lifting component is activated to push the connecting plate to rise and fall. The rising and falling of the connecting plate drives the first spray pipe to rise and fall, thereby adjusting the insertion depth of the first nozzle. The connecting hose increases the flexibility of the first spray pipe's rising and falling.

[0020] Optionally, the lifting component is an electric actuator, and there are two electric actuators. The two electric actuators are located on the medicine tank and on both sides of the first spray pipe, corresponding one-to-one with the connecting plate. The telescopic end of the electric actuator is connected to the connecting plate.

[0021] By adopting the above technical solution, two electric actuators drive the two connecting plates respectively, which not only improves the convenience of raising and lowering the first spray pipe, but also allows the tilt angle of the first spray pipe to be adjusted according to the terrain, thereby improving the penetration efficiency of the remediation liquid and improving the soil remediation effect.

[0022] Optionally, the mobile frame is equipped with a shield that covers the tiller blades and is connected to the pesticide tank to prevent soil splashing.

[0023] By adopting the above technical solution, the shielding cover blocks the soil that splashes out as the tiller rotates. After being blocked, the soil is gathered inside the shielding cover. At this time, as the moving wheel moves, the soil enters below the agent tank, the first spray pipe descends and the first nozzle is inserted into the soil. By blocking and gathering the soil through the shielding cover, the effectiveness of the remediation solution is improved, thereby improving the soil remediation effect.

[0024] Optionally, the mobile frame is equipped with a protective box to protect the drive motor.

[0025] By adopting the above technical solution, the protective box reduces the probability of soil splashing into the drive motor and causing damage to the motor.

[0026] Optionally, the medicine tank is equipped with a level gauge.

[0027] By adopting the above technical solution, the level gauge displays the level of the repair fluid in the tank, making it convenient for operators to replenish it in a timely manner.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The mobile frame moves to the repair point via the wheels. The soil breaking component is activated to break up the soil, making it loose. Then the spraying component sprays the repair liquid onto the soil. Since the soil is now loose, the penetration efficiency of the repair liquid is improved, thereby improving the efficiency of soil repair.

[0030] 2. After the soil is broken up, the lifting device lowers the first spray pipe until the first nozzle is inserted into the soil. The loose soil makes it easier to insert the first nozzle. The first spray pump starts, and the remediation liquid is sprayed from the first nozzle, thereby increasing the penetration height of the remediation liquid and thus increasing the depth of soil remediation. As the moving wheels move, the first spray pipe moves synchronously, and the soil is gradually removed from the moving frame. The second spray pump starts, drawing the remediation liquid into the second spray pipe and spraying it out through the atomizing nozzle, thereby spraying the remediation liquid onto the soil surface. The loose soil increases the penetration efficiency of the remediation liquid. The first and second spray pipes work together to improve the effectiveness of the remediation liquid, spraying both the soil interior to increase the penetration height and the surface soil to enhance the effect of the remediation liquid, thus improving the efficiency of soil remediation.

[0031] 3. By using two electric actuators to drive the two connecting plates respectively, not only is the ease of raising and lowering the first spray pipe improved, but the tilt angle of the first spray pipe can also be adjusted according to the terrain, thereby improving the penetration efficiency of the remediation liquid and enhancing the soil remediation effect.

[0038] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0039] This application discloses a soil remediation device for environmental governance.

[0040] Reference Figure 1 and Figure 2 A soil remediation device for environmental governance includes a mobile frame 1, a reagent tank 2, a soil breaking component 3, and a spraying component 4.

[0041] Reference Figure 1 and Figure 2 The mobile frame 1 has four wheels 11, which are rotatably located at the four corners of the mobile frame 1 and are used to drive the mobile frame 1 to move. In this embodiment, the front end of the mobile frame 1 is driven by a tractor. In other feasible embodiments, the mobile wheels 11 can also be driven by other towing equipment, or a motor can be set to drive the mobile wheels 11 to rotate, so as to realize the forward movement of the mobile frame 1.

[0045] Reference Figure 1 , Figure 2 and Figure 4 The spray assembly 4 includes a first spray pipe 41 and a second spray pipe 42.

[0046] Reference Figure 2 , Figure 4 and Figure 5 The first spray pipe 41 is located on the movable frame 1, below the medicine tank 2 and behind the tiller 32. The length extension direction of the first spray pipe 41 is consistent with the extension direction of the axis of the rotating shaft 31. The length of the first spray pipe 41 is less than the width of the space inside the movable frame 1. Multiple vertically downward extending first nozzles 411 are provided at intervals on the lower surface of the first spray pipe 41. Multiple spray holes for spraying repair liquid are distributed on the lower surface and outer wall of the first nozzles 411 (not shown in the figure).

[0047] Reference Figure 2 , Figure 3 and Figure 4 A first spray pump 23 is fixed on the outer wall of the agent tank 2. The suction end of the first spray pump 23 extends into the agent tank 2. The output end of the first spray pipe 41 is connected to the first spray pipe 41 through the connecting hose 231. The moving frame 1 is equipped with a lifting component 5 that drives the first spray pipe 41 to rise and fall. In the initial state, the spray pipe is located in the space formed by the four columns. When spraying, the first nozzle 411 is inserted into the soil under the action of the lifting component 5.

[0048] Reference Figure 2 , Figure 3 and Figure 5Both ends of the first spray pipe 41 are fixed with connecting plates 43. The lifting component 5 is an electric push rod 51. There are two electric push rods 51, which correspond one-to-one with the connecting plates 43. The electric push rods 51 are fixed on the outer wall of the medicine tank 2 and the telescopic ends extend vertically. The two electric push rods 51 are located on both sides of the first spray pipe 41. The telescopic ends of the electric push rods 51 are fixedly connected to the corresponding connecting plates 43. There is a gap between the side wall of the medicine tank 2 and the support frame 12 for the telescopic ends of the electric push rods 51 and the connecting hose 231 to move.

[0049] Reference Figure 2 , Figure 3 and Figure 5 The two electric actuators 51 not only improve the stability and convenience of raising and lowering the first spray pipe 41, but also adjust the extension and retraction process of the two electric actuators 51 according to the terrain, thereby adjusting the tilt angle of the first spray pipe 41, thus improving the penetration efficiency of the remediation liquid and improving the soil remediation effect.

[0050] Reference Figure 2 , Figure 3 and Figure 4 Two support rods 15 are fixed at the rear of the mobile frame 1. The second spray pipe 42 is fixed on the two support rods 15 and located on the side of the pesticide tank 2 away from the tillage blade 32. The length direction of the second spray pipe 42 is consistent with the length direction of the first spray pipe 41. The second spray pipe 42 is equipped with multiple atomizing nozzles 421, which are located above the soil. The pesticide tank 2 is equipped with a second spray pump 24. The suction end of the second spray pump 24 extends into the pesticide tank 2, and the output end of the second spray pump 24 is connected to the second spray pipe 42. The height of the second spray pipe 42 is higher than the height of the shield 14 to facilitate spraying the broken and loose soil.

[0051] The working principle of this application embodiment is as follows:

[0052] The mobile frame 1 moves to the soil remediation point, and the drive motor 33 drives the tillage blade 32 to break up the soil. The broken soil gathers in the cover 14. As the mobile frame 1 moves, the soil moves to the bottom of the agent tank 2. At this time, the electric push rod 51 is activated to push the first spray pipe 41 to move the first nozzle 411 down and insert it into the broken soil. The loose soil increases the ease of insertion of the first nozzle 411. Under the action of the first spray pump 23, the remediation liquid is sprayed into the soil through the connecting hose 231, the first spray pipe 41 and the first nozzle 411, thereby increasing the penetration height of the remediation liquid and thus increasing the depth of soil remediation.

[0053] As the moving wheels 11 move, the first spray pipe 41 moves synchronously, and the soil gradually moves out of the moving frame 1. The second spray pump 24 starts to draw the remediation liquid into the second spray pipe 42 and spray it out through the atomizing nozzle 421, thereby spraying the remediation liquid onto the soil surface. The loose state of the soil increases the efficiency of the remediation liquid penetration. The first spray pipe 41 and the second spray pipe 42 work together to improve the use effect of the remediation liquid. It can spray the soil inside, increasing the penetration height of the remediation liquid, and also spray the surface soil, enhancing the effect of the remediation liquid, thereby improving the efficiency of soil remediation.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
