Description

Technical Field

[0001] This invention relates to the field of soil pollution control and improvement technology, specifically to an integrated device for ecological restoration of soil pollution control and improvement. Background Technology

[0002] Soil is a vital component of the ecosystem, and its health directly impacts agricultural production, environmental safety, and human health. With industrialization and urbanization, soil pollution has become increasingly severe, primarily involving heavy metals and organic pollutants. Existing soil remediation technologies include topsoil replacement, chemical leaching, solidification / stabilization, and phytoremediation.

[0003] Currently, most technologies separate "pollution remediation" (such as passivation and leaching) and "soil improvement" (such as fertilization, acidification, and structural improvement) into two independent, sequential processes. This prolongs the remediation cycle, increases the cost of mechanical operations, and can easily cause secondary disturbances or nutrient loss during the transition between different processes.

[0004] Furthermore, traditional methods of spreading and mixing remediation agents or amendments cannot ensure thorough and uniform mixing with the soil, especially deep soil layers. This leads to an "island" effect in the remediation effect, with both excessive and insufficient amounts in certain areas, affecting the overall remediation efficiency and quality.

[0005] In addition, many remediation processes (especially chemical leaching) may damage soil aggregate structure, reduce porosity, and exacerbate compaction, resulting in the negative effect of "clean but barren, clean but compacted", which weakens the ecological function and production potential of the soil and requires subsequent additional investment to improve its physical structure.

[0006] Therefore, it is necessary to provide an integrated device for soil pollution control and improvement for ecological restoration, in order to solve the problems mentioned in the background art. Summary of the Invention

[0008] The processing box has a material transfer cylinder cavity inside, and the front and rear parts of the material transfer cylinder cavity are respectively connected to the material transfer device and the liquid device. The inner wall of the middle part of the material transfer cylinder cavity is equipped with a hanging frame.

[0009] A rotating rod is coaxially arranged with the material conveying cylinder cavity and rotates on the hanging frame. A screw blade is sleeved on the outer wall of the middle part, and a crushing rod is provided at the front end. A belt drive device connected to the rotating rod is provided in the hanging frame.

[0013] As an improvement, the material transfer device includes:

[0014] The main material pipe is located on the processing box, and the main screw blade runs through the inside of the pipe;

[0015] The branch pipe is connected to the main pipe, and its pipe is equipped with a branch screw and a motor for regulating the rotation of the branch screw.

[0016] The discharge pipe connects the branch pipe to the front chamber of the material conveying cylinder.

[0017] As an improvement, the liquid medicine device includes:

[0018] The main liquid pipe is located on the treatment tank;

[0019] The annular pipe is located on the inner wall of the rear chamber of the material transfer cylinder and is connected to the main liquid pipe. Nozzles are distributed on its annular wall.

[0020] As an improvement, the material holes of the extrusion plate and the cutting holes of the dividing plate are distributed correspondingly, and the material holes of the extrusion plate and the cutting holes of the dividing plate are aligned every time the dividing plate rotates by an angle δ.

[0021] As an improvement, the rotating rod is respectively provided with a stirring rod one located behind the material transfer device and a stirring rod two located behind the liquid medicine device;

[0022] The rear end of the rotating rod is provided with a scraper that contacts the front end face of the extrusion hole disc.

[0023] As an improvement, the drive device includes:

[0024] Motor 1 is located at the front end of the slot cavity, and its output end is equipped with a shaft;

[0025] The roller, sleeved on the shaft, makes rolling contact with the outer ring wall of the dividing hole plate;

[0026] The sealing sleeve is fitted over the shaft and is fixed by friction against the inner wall of the groove.

[0027] As an improvement, the outer wall of the extrusion hole disc is provided with a lug that is sleeved on the outside of the shaft and is fixed by friction with the inner wall of the groove cavity.

[0028] As an improvement, it also includes:

[0029] The bracket has a lifting cylinder at its rear end, and a hanger is installed at the lower end of the lifting cylinder.

[0030] Multiple processing modules are arranged side by side and fixed by a frame. They are then installed at the lower end of the hanger. The material transfer device and the liquid medicine device in one of the processing modules located on the side are respectively connected to the powder supply device and the liquid medicine supply pipe.

[0031] As an improvement, the powder supply device includes:

[0032] The material conveying pipe is mounted on the hanger. Its bottom is equipped with a protective box and a supply port. The protective box is equipped with two screw blades corresponding to the supply port and a belt drive device for adjusting the rotation of the two screw blades.

[0033] Motor 3 is located at the upper end of the feed tube, and its output end is connected to screw blade 3 that extends into the feed tube.

[0034] Compared with existing technologies, the present invention provides an integrated device for soil pollution treatment and improvement for ecological restoration, which has the following beneficial effects:

[0035] In this invention, a continuous process line is constructed by sequentially arranging a crushing rod, a material conveying device, a liquid agent device, and a material extrusion plate in the material conveying cylinder of the same processing box. During a single feeding process, the soil can be crushed, mixed with solid amendments, sprayed with liquid agents for treatment, and finally discharged in a shaped form. This completely changes the traditional step-by-step operation mode, greatly improves the remediation efficiency, and reduces the overall cost.

[0036] In this invention, the soil is finely pulverized by a front-mounted pulverizing rod, increasing the soil's specific surface area and porosity. Secondly, two separate stirring rods are used to specifically stir the solid powder and liquid agents, forming a combined force with the conveying and stirring of the screw blade, creating a multi-stage, forced mixing mechanism. This ensures the uniform distribution of the remediation agent and amendment agent in the three-dimensional space of the soil, overcoming the drawbacks of uneven application in traditional methods and improving the uniformity and reliability of the remediation and amendment effects.

[0037] In this invention, the physical structure of the soil is improved simultaneously through granulation molding. Specifically, the combined design of the extrusion and dividing discs at the end forces the treated soft soil to be extruded and cut into regular granules. This not only completes the discharge but also actively shapes the aggregate structure of the soil. The resulting granular soil has higher porosity, better air permeability, and water retention, effectively avoiding soil compaction problems that may occur during the remediation process. This achieves "remediation is improvement" and directly produces remediated soil with a better physical structure.

[0038] In this invention, the depth of the entire device in the soil can be precisely controlled by a lifting cylinder, enabling targeted remediation of different soil layers (such as the topsoil and contaminated layers). Multiple processing modules can be installed side by side in a frame, easily expanding the working width to meet the needs of sites of different sizes. By changing the extrusion discs with different apertures and adjusting the intermittent frequency of the drive device, the size of the produced soil particles can be controlled to adapt to different subsequent utilization needs (such as greening and arable land). The independent supply of the material transfer device and the liquid treatment device also allows for flexible adjustment of the order and proportion of solid and liquid materials added according to the actual pollution and remediation needs.

[0045] Reference Figures 1-5 This invention provides a technical solution: an integrated device for soil pollution treatment and improvement for ecological restoration, comprising a processing module 5, wherein the processing module 5 includes:

[0046] The processing box 51 has a material transfer cylinder 517 inside, and the front and rear parts of the material transfer cylinder 517 are respectively connected to the material transfer device 510 and the liquid medicine device 511. The inner wall of the middle part of the material transfer cylinder 517 is provided with a hanging frame 52. The material transfer device 510 is used for solid nutrient powders required for soil improvement, and the liquid medicine device 511 is used for agents required for soil pollution control.

[0047] The rotating rod 53 is coaxially arranged with the material conveying cylinder cavity 517 and rotates on the hanging frame 52. The outer wall of the middle part is fitted with a screw blade 54, and the front end is provided with a crushing rod 56. The hanging frame 52 is provided with a belt drive device 55 connected to the rotating rod 53.

[0048] The extrusion hole disk 57 is located at the rear end of the material transfer cylinder cavity 517, and its rear end face contacts the dividing hole disk 58 rotating in the material transfer cylinder cavity 517.

[0049] The groove cavity 591 is located at the rear end of the material conveying cylinder cavity 517, and a drive device 59 for adjusting the rotation of the dividing hole disk 58 is provided inside it.

[0050] In this embodiment, before the soil pollution remediation and improvement operation, the soil is pre-crushed into small particles by external equipment so that the soil can pass smoothly through the material transfer cylinder 517 when the lifting treatment box 51 moves forward in the soil. In addition, the crushing rod 56 is located at the front end of the material transfer cylinder 517 so that the soil can be further crushed when it enters the material transfer cylinder 517. The crushing rod 56 is located inside the material transfer cylinder 517, that is, after the soil enters the material transfer cylinder 517, the crushing rod 56 crushes the soil inside the material transfer cylinder 517 to prevent the loose and diffused soil during the crushing process from flowing to the outside of the material transfer cylinder 517.

[0051] The material transfer device 510 introduces solid nutrient powder into the material transfer cylinder 517 chamber between the screw blade 54 and the crushing rod 56. In other words, the soil crushed by the crushing rod 56 has a looser and more uniform effect, with a good void distribution, so that the solid nutrient powder can be efficiently mixed into the soil, and the mixing of the solid nutrient powder and the soil can be more thorough and the distribution more uniform.

[0052] The liquid medicine device 511 introduces the medicine into the material transfer cylinder 517 chamber between the screw blade 54 and the extrusion plate 57. That is to say, after the soil mixed with solid nutrient powder is actively transferred backward by the screw blade 54, it should be noted that the solid nutrient powder may not be mixed with the soil. Depending on the specific situation, the appropriate steps are performed, and then it is fully mixed with the medicine in order to remediate and treat the soil.

[0053] In this embodiment, the rotation of the dividing plate 58 is controlled by the driving device 59, which can cut the soil in the material hole of the extrusion plate 57 to form granular soil, which is then discharged from the rear end of the conveying cylinder 517. This results in a significant increase in the porosity of the treated soil. Furthermore, the corresponding extrusion plate 57 and dividing plate 58 are designed and replaced according to the required soil particle state. Therefore, the treated soil is not only effectively treated and improved, but also has a good loose state.

[0054] In this embodiment, the front and rear ends of the processing box 51 are respectively connected to the inlet 512 and the outlet 513, and the inlet 512 has a trapezoidal structure so that when the processing box 51 moves forward in the soil, the soil layer at the depth of the processing box 51 can smoothly and accurately enter the processing box 51 and then be discharged.

[0055] In this embodiment, the material transfer device 510 includes:

[0056] The main material pipe 5101 is located on the processing box 51, and the main screw blade 5103 passes through the pipe.

[0057] The branch pipe 5102 is connected to the main pipe 5101, and its pipe is equipped with a branch screw 5105 and a motor 5104 for regulating the rotation of the branch screw 5105.

[0058] The discharge pipe 5106 connects the branch pipe 5102 to the front chamber of the material transfer cylinder 517.

[0059] The branch pipe 5102 is connected to the middle of the main pipe 5101. The main pipe 5101, centered on the branch pipe 5102, has main screw blades 5103 on both sides inside to improve the smoothness of the flow of solid nutrient powder inside the main pipe 5101. In addition, when multiple processing modules 5 are installed in parallel, the adjacent main screw blades 5103 in each processing module 5 are connected and fixed by short sleeves, so that the main screw blades 5103 in multiple processing modules 5 can rotate synchronously. Then, they are connected and fixed to the screw blades 76 connected to the belt drive device 2 72. Therefore, the synchronous rotation control of the screw blades 76 and all main screw blades 5103 can be achieved by driving and controlling the belt drive device 2 72.

[0060] In this embodiment, the liquid medicine device 511 includes:

[0061] The main liquid pipe 5111 is located on the treatment tank 51;

[0062] The annular pipe 5112 is located on the inner wall of the rear chamber of the material transfer cylinder 517 and is connected to the main liquid pipe 5111. Nozzles 5113 are distributed on its annular wall.

[0063] When multiple processing modules 5 are installed in parallel, the adjacent main liquid pipes 5111 in each processing module 5 are nested and fixed by an inner sleeve, so that the main liquid pipes 5111 in multiple processing modules 5 can be connected together. Then, they are connected to the drug supply pipe 6, and the drug supply pipe 6 can supply the drug to all the main liquid pipes 5111.

[0064] In this embodiment, the material holes of the extrusion plate 57 and the cutting holes of the dividing plate 58 are correspondingly distributed, and the material holes of the extrusion plate 57 and the cutting holes of the dividing plate 58 are aligned every time the dividing plate 58 rotates by an angle δ. That is, the driving device 59 controls the rotation of the dividing plate 58 in an intermittent manner. That is, when the soil is extruded from the material hole of the extrusion plate 57 for a certain length, the driving device 59 controls the dividing plate 58 to rotate by an angle δ, and the dividing plate 58 will separate the extruded soil to form a granular state. In this embodiment, δ is a 60° included angle, that is, when the material hole of the extrusion plate 57 and the cutting hole of the dividing plate 58 are aligned, the dividing plate 58 will complete a cutting process every time it rotates by an angle of 60°.

[0065] In this embodiment, the rotating rod 53 is respectively provided with a stirring rod 514 located behind the material transfer device 510 and a stirring rod 515 located behind the liquid medicine device 511, so as to improve the mixing effect of solid nutrient powder and soil and improve the mixing effect of medicine and soil.

[0066] The rear end of the rotating rod 53 is provided with a scraper 516 that contacts the front end face of the extrusion orifice plate 57, so as to prevent soil from accumulating on the front end face of the extrusion orifice plate 57 and improve soil fluidity.

[0067] In this embodiment, the driving device 59 includes:

[0068] Motor 592 is located at the front end of slot cavity 591, and its output end is provided with shaft 593;

[0069] Roller 594 is fitted on shaft 593 and makes rolling contact with the outer ring wall of dividing hole plate 58;

[0070] The sealing sleeve 595 is fitted over the shaft 593 and is fixed by friction against the inner wall of the groove 591.

[0071] The outer wall of the extrusion hole disk 57 is provided with a hanging ear 571 that is sleeved on the shaft 593 and is fixed by friction with the inner wall of the groove cavity 591.

[0072] In this embodiment, the length of the material holes of the extrusion plate 57 can be extended by stacking the thickness of the extrusion plate 57. By extending the length of the material holes, it is beneficial to increase the relative time that soil particles stay in the material holes, thereby improving the compaction effect of soil extrusion in the material holes. Therefore, the design of the drive device 59 facilitates the installation and disassembly of the number of extrusion plate 57, and also facilitates the assembly of the roller 594 and the dividing plate 58.

[0073] This embodiment also includes:

[0074] The bracket 1 has a lifting cylinder 2 at its rear end, and a hanger 3 is installed at the lower end of the lifting cylinder 2.

[0075] Multiple processing modules 5 are arranged in parallel and fixed by a frame 4. They are then installed at the lower end of the hanger 3. The material transfer device 510 and the liquid medicine device 511 in one of the processing modules 5 located on the side are respectively connected to the powder supply device 7 and the liquid medicine supply pipe 6.

[0076] In other words, specifically, the bracket 1 is connected to an agricultural mobile device for pulling, and the position of the hanger 3 is adjusted by the lifting cylinder 2, thereby controlling the depth of the processing module 5 in the soil layer, so as to accurately process the required soil layer.

[0077] In this embodiment, the powder supply device 7 includes:

[0078] The material conveying pipe 71 is mounted on the hanger 3. Its bottom is equipped with a protective box 75 and a supply port 74. The protective box 75 is equipped with a screw blade 73 corresponding to the supply port 74 and a belt drive device 72 for adjusting the rotation of the screw blade 73.

[0079] Motor 3 77 is located at the upper end of the material transfer tube 71, and its output end is connected to screw blade 3 76 extending into the material transfer tube 71.

[0080] In other words, by controlling the screw blades 376 downwards through motor 377, the material is facilitated to be smoothly transmitted through the solid nutrient powder.

[0081] In practice, the specific work process is as follows:

[0082] Step 1: The soil is pulled forward through the soil by external agricultural equipment. The trapezoidal feed port 512 at the front of the processing box 51 collects soil at a specific depth and introduces it into the conveying cylinder 517. The soil first enters the front of the cavity and is broken up and crushed by the crushing rod 56 at the front of the rotating rod 53, so that the soil particles are fine, loose and uniform, creating favorable conditions for subsequent efficient mixing.

[0083] Step 2: The crushed soil is pushed backward, and the material conveying device 510 starts to work. Solid nutrient powder is supplied from the powder supply device 7 through the material conveying pipe 71. Through the parallel connected main material pipes 5101 and branch material pipes 5102, it is finally accurately introduced from the discharge pipe 5106 into the chamber behind the crushing rod 56. It is mixed with the loose soil under the special stirring of the mixing rod 514, and then conveyed by the screw blade 54.

[0084] Step 3: The soil mixed with solid nutrient powder continues to be conveyed backward by the first screw blade 54 and enters the rear section of the chamber. At this time, the liquid treatment device 511 is activated. The treatment agent is conveyed through the liquid supply pipe 6 and the main liquid pipe 5111 connecting each module to the ring pipe 5112, and is atomized and sprayed out by the nozzles 5113 distributed on its ring wall, and evenly sprinkled on the soil. Under the subsequent conveying and the enhanced stirring of the second stirring rod 515, the agent comes into full contact with the soil, and completes the treatment reaction such as chemical fixation, degradation or leaching of pollutants.

[0085] Step 4: The treated and improved soft soil is pushed to the extrusion plate 57 at the end of the conveyor cylinder 517. Under the continuous pressure provided by the screw blade 54, the soil is squeezed out from the material hole of the extrusion plate 57 to form strips. At the same time, the motor 592 in the drive device 59 starts and drives the roller 594 to rotate intermittently through the shaft 593, thereby driving the dividing plate 58 in contact with it to rotate periodically, for example, every 60°. When the dividing plate rotates a certain angle δ so that the solid part is aligned with the material hole, the extruded soil strip is cut off to form uniformly sized granular soil. Finally, the granular soil is discharged from the outlet 513 and returned to its original position, which increases the porosity of the treated soil and improves its loose and breathable physical structure.

[0086] The above description is merely a preferred embodiment of the invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
