Description

Technical Field

[0001] This utility model belongs to the field of soil remediation technology, and in particular relates to a mobile organic pollution remediation device. Background Technology

[0002] Organically polluted soil remediation refers to technical measures that utilize physical, chemical, biological, and ecological principles, along with artificial control measures, to reduce the concentration of soil pollutants, thereby rendering them harmless and stabilizing them to achieve the desired detoxification effect. Currently, theoretically feasible remediation technologies include several major categories such as phytoremediation, microbial remediation, chemical remediation, physical remediation, and integrated remediation.

[0003] Chemical remediation primarily involves using chemical additives to remove and reduce pollutants in the environment. Chemical remediation generally has a broad spectrum of effectiveness, can treat multiple pollutants at once, and offers rapid treatment with high pollutant decomposition rates.

[0004] Chemical remediation methods are mainly divided into in-situ and ex-situ methods. Traditional in-situ soil chemical remediation technology generally uses injection wells or boreholes, without excavating the contaminated soil, directly injecting the chemical agent into the ground for remediation. In-situ soil remediation is low-cost and requires minimal construction, but it generally suffers from unstable treatment effects and difficulty in monitoring. In contrast, ex-situ soil remediation has the advantages of rapid effectiveness, strong targeting, and small chemical dosage, but it requires excavating the contaminated soil for treatment, so it is generally used for small areas with high contamination concentrations. Most ex-situ chemical remediation equipment adopts a process of crushing → screening → soil and chemical mixing → end-of-pipe treatment → discharge. However, currently available ex-situ remediation equipment often suffers from drawbacks such as large size, difficulty in transportation, poor chemical-soil mixing effect, numerous accessories, and complex processes, which affect its practical application.

[0005] Therefore, a mobile organic pollution remediation device that is lightweight, simple, easy to transport, and has a good mixing effect between chemicals and soil is proposed. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a mobile organic pollution remediation device.

[0007] To achieve the above objectives, this utility model provides a mobile organic pollution remediation device, comprising:

[0008] Mounting plate;

[0009] The movable component is provided in two sets, which are respectively connected to the front and rear sides of the bottom of the mounting plate; the movable component includes a rotating shaft, and two movable wheels are rotatably connected to both ends of the rotating shaft; the rotating shaft is connected to the mounting plate through a hydraulic telescopic rod.

[0010] A crushing assembly, installed in front of the mounting plate, is used to crush the ground.

[0011] A turning and throwing assembly is installed behind the crushing assembly and is used to turn and throw the ground. The turning and throwing assembly is covered with an outer cover, which is fixed to the bottom surface of the mounting plate.

[0012] The spraying assembly includes a medicine tank, which is fixedly connected to the mounting plate. The bottom of the medicine tank is connected to a plurality of nozzles, which pass through the mounting plate and the outer cover and communicate with the interior of the outer cover.

[0013] Preferably, the crushing assembly includes a crushing roller, a plurality of ground nails are fixedly connected to the outer circumference of the crushing roller, and a first connecting plate is rotatably connected to both ends of the crushing roller, the first connecting plate being fixed to the bottom surface of the mounting plate.

[0014] Preferably, the tumbling assembly includes a tumbling roller, a plurality of L-shaped blades are fixedly connected to the circumferentially of the tumbling roller, and a second connecting plate is rotatably connected to both ends of the tumbling roller through the outer cover. The second connecting plate is fixedly connected to the bottom surface of the mounting plate, and a tumbling motor is drivenly connected to one end of the tumbling roller. The tumbling motor is fixedly connected to the outer cover.

[0015] Preferably, the bending directions of two adjacent L-shaped blades are opposite.

[0016] Preferably, a stirring shaft is rotatably connected inside the medicine box, and several stirring rods are fixedly connected to the stirring shaft. A stirring motor is driven through the top of the stirring shaft and connected to the top of the medicine box. The stirring motor is fixedly connected to the top of the medicine box.

[0017] Preferably, the top of the medicine box has a feed inlet, and an end cap is threaded onto the feed inlet.

[0018] Preferably, the outer cover is arched, semi-enclosing the throwing assembly. Several nozzles pass through the outer cover and are connected to branch pipes.

[0019] Preferably, a tension bracket is fixedly connected to the front end of the mounting plate.

[0020] Compared with the prior art, the present invention has the following advantages and technical effects:

[0021] This mobile organic pollution remediation device features four core components arranged in an orderly fashion on the mounting plate: movement, crushing, turning, and spraying, forming a highly efficient remediation system with synergistic functions. The hydraulic telescopic rod extends and retracts, adjusting the height of the mounting plate above the ground. Since the mounting plate is connected to the crushing and turning components, the distance between these components and the ground can also be adjusted. When not in use, the hydraulic telescopic rod extends, raising the crushing and turning components above the ground, facilitating device movement and solving the problems of poor mobility and inconvenient transportation associated with traditional off-site remediation equipment. Once in the work area, the hydraulic telescopic rod retracts, allowing the crushing and turning components to be inserted into the ground at an adjustable depth, facilitating the crushing and turning of soil within the target depth. The front-end crushing component can break up compacted soil and remove clumps, making it easier for the subsequent turning component to turn the soil. The turning and turning assembly is equipped with an outer cover, forming a closed working space with the internal turning and turning structure. This prevents soil splashing during the turning process and creates a concentrated area for the spraying assembly to apply the chemicals. The nozzles running through the outer cover are directly connected to the chemical tank, allowing for precise spraying of remediation chemicals onto the loose soil flow during turning. The turning action achieves dynamic mixing of the chemicals and soil, avoiding the uneven mixing and waste of chemicals caused by the traditional "crush first, then spray" method. The overall design realizes a continuous operation of the entire process from "crushing—turning—application," combining advantages such as mobility, pretreatment effect, uniform mixing, and controllable chemical spraying. This effectively improves the quality and efficiency of remediation of organically contaminated soil, and is especially suitable for the rapid remediation of small to medium-sized areas with high concentrations of contamination. It overcomes the technical shortcomings of existing technologies, such as bulky equipment, complex processes, and unstable remediation effects. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 5 As shown, this embodiment provides a mobile organic pollution remediation device, including:

[0032] Mounting plate 1;

[0033] The movable component 2 is provided in two sets, which are respectively connected to the front and rear sides of the bottom of the mounting plate 1; the movable component 2 includes a rotating shaft 201, and two movable wheels 202 are rotatably connected to both ends of the rotating shaft 201; the rotating shaft 201 is connected to the mounting plate 1 through a hydraulic telescopic rod 203.

[0034] The crushing component 3 is installed in front of the mounting plate 1 and is used to crush the ground.

[0035] The turning and throwing component 4 is installed behind the crushing component 3 and is used to turn and throw the ground. The outer cover 401 of the turning and throwing component 4 is provided and the outer cover 401 is fixed to the bottom surface of the mounting plate 1.

[0036] The spraying assembly 5 includes a medicine tank 501, which is fixedly connected to the mounting plate 1. Several nozzles 502 are connected to the bottom of the medicine tank 501. The nozzles 502 pass through the mounting plate 1 and the outer cover 401 and communicate with the inside of the outer cover 401.

[0037] This mobile organic pollution remediation device features four core components—movement, crushing, turning, and spraying—arranged in an orderly fashion on the mounting plate 1, forming a highly efficient remediation system with synergistic functions. The hydraulic telescopic rod 203 extends and retracts, adjusting the height of the mounting plate 1 above the ground. Since the mounting plate 1 is connected to the crushing component 3 and the turning component 4, the distance between these components and the ground can also be adjusted. When not in use, the hydraulic telescopic rod 203 extends, raising the crushing component 3 and the turning component 4 above the ground, facilitating device movement and solving the problems of poor mobility and inconvenient transportation associated with traditional off-site remediation equipment. Upon entering the work area, the hydraulic telescopic rod 203 retracts, allowing the crushing component 3 and the turning component 4 to be inserted into the ground at an adjustable depth, facilitating the crushing and turning of soil within the target depth. The front-end crushing component 3 can break up compacted soil and remove clumps, making it easier for the subsequent turning component 4 to turn the soil. An outer cover 401 is installed on the outside of the turning and scattering component 4, forming a closed working space with the internal turning and scattering structure. This not only prevents soil splashing during the turning and scattering process but also creates a concentrated area for the spraying component 5 to act as a chemical agent. The nozzle 502 penetrating the outer cover 401 is directly connected to the chemical tank 501, allowing for precise spraying of remediation agents onto the loose soil flow during the turning and scattering process. The turning and scattering action achieves dynamic mixing of the agent and soil, avoiding the uneven mixing and agent waste problems caused by the traditional equipment's "crush first, then spray" method. The overall design realizes a continuous operation of the entire process of "crushing—turning and scattering—chemical application," combining the advantages of mobility, pretreatment effect, uniform mixing, and controllable agent spraying. It effectively improves the quality and efficiency of remediation of organically contaminated soil, and is especially suitable for the rapid remediation of small to medium-sized areas with high concentrations of contaminated soil. It overcomes the technical defects of existing technologies, such as bulky equipment, complex processes, and unstable remediation effects.

[0038] Further optimization of the scheme: the crushing component 3 includes a crushing roller 301, a number of ground nails 302 are fixedly connected to the outer circumference of the crushing roller 301, and a first connecting plate 303 is rotatably connected to both ends of the crushing roller 301. The first connecting plate 303 is fixedly connected to the bottom surface of the mounting plate 1.

[0039] The crushing roller 301 of the crushing component 3 rolls due to friction with the ground as the device moves forward. Several ground spikes 302 are fixed to the outer circumference of the crushing roller 301. This structure, through the piercing, striking and crushing action of the ground spikes 302 on the compacted soil as the crushing roller 301 rotates, can efficiently break up the clumps and hardened layers of surface and shallow soil, breaking large soil clumps into smaller particles, significantly increasing the soil surface area. This creates favorable conditions for the subsequent full turning of the turning and throwing component 4 and the uniform penetration of the agent by the spraying component 5. At the same time, both ends of the crushing roller 301 are fixed to the bottom surface of the mounting plate 1 through the first connecting plate 303. The structure is simple and stable, ensuring that the crushing roller 301 remains stable when rotating at high speed, and is easy to disassemble and maintain. Combined with the overall mobility of the device, soil crushing pretreatment can be completed simultaneously during the movement, improving the continuity and efficiency of the remediation process, and effectively solving the problem of insufficient contact between the agent and soil caused by insufficient pretreatment in traditional remediation equipment.

[0040] The scheme is further optimized. The turning and shoveling component 4 includes a turning and shoveling roller 402. Several L-shaped blades 403 are fixedly connected to the turning and shoveling roller 402 in the circumferential direction. The two ends of the turning and shoveling roller 402 pass through the outer cover 401 and are rotatably connected to a second connecting plate 404. The second connecting plate 404 is fixedly connected to the bottom surface of the mounting plate 1. One end of the turning and shoveling roller 402 is drivenly connected to a turning and shoveling motor 405, which is fixedly connected to the outer cover 401.

[0041] The turning roller 402 of the turning and shoveling assembly 4 is driven by the turning and shoveling motor 405. Several L-shaped blades are fixedly connected to the turning and shoveling roller 402 around its circumference. Through the unique bending design of the L-shaped blades, this structure can penetrate deep into the broken soil layer when the turning and shoveling roller 402 rotates, realizing powerful turning, cutting and loosening of the soil: after the vertical section of the blade is inserted into the soil, the horizontal section lifts the soil clods upward and throws them with the direction of rotation, effectively breaking up soil agglomerates, making the particle distribution more uniform, and increasing the contact area between the soil and the air and the remediation agent. The two ends of the turning and shoveling roller 402 are fixed to the bottom surface of the mounting plate 1 through the second connecting plate 404 to ensure stability during high-speed rotation. With the semi-enclosed structure of the outer cover 401, a closed turning and shoveling space is formed to prevent soil splashing and concentrate the agent spraying area, so that the agent of the spraying assembly 5 can be fully mixed with the soil during the turning and shoveling process, significantly improving the uniformity of the agent and soil and the reaction efficiency. This solves the problems of incomplete turning and shoveling and poor mixing effect of traditional remediation equipment, and lays a good foundation for subsequent remediation reaction.

[0042] The design was further optimized so that the bending directions of two adjacent L-shaped blades 403 were opposite.

[0043] The design of two adjacent L-shaped blades bending in opposite directions enables all-round three-dimensional turning of the crushed soil, avoiding soil agglomeration or dead corners in the turning process, and improving the effect of turning and refining soil particles.

[0044] In a further optimized design, a stirring shaft 503 is rotatably connected inside the medicine box 501. Several stirring rods 504 are fixedly connected to the stirring shaft 503. The top of the stirring shaft 503 passes through the top surface of the medicine box 501 and is connected to a stirring motor 505. The stirring motor 505 is fixedly connected to the top of the medicine box 501.

[0045] The mixing shaft 503 and mixing rod 504 structure inside the tank 501, driven by the mixing motor 505, continuously mixes the remediation agent within the tank 501, effectively preventing solid particle sedimentation or component stratification, ensuring uniform and stable agent concentration, and avoiding problems such as efficacy attenuation or excessively high local concentrations caused by prolonged static placement. The multi-directional arrangement of the mixing rod 504 expands the mixing range, and combined with the enclosed space of the tank 501, achieves efficient mixing of the agent, ensuring that the agent sprayed from the nozzle 502 always maintains the optimal reaction state, improving the reaction efficiency with contaminated soil. The design of the mixing motor 505 fixed to the top of the tank 501 is compact and easy to disassemble and maintain, ensuring coordinated operation of the mixing system and the overall device. Especially during equipment movement, it can dynamically maintain agent uniformity, laying a reliable foundation for subsequent precise spraying and soil remediation, and solving the problem of agent failure or unstable remediation effect caused by the lack of mixing in traditional tanks 501.

[0046] The design has been further optimized. The top of the medicine box 501 has a feed inlet 506, and an end cap 507 is threaded onto the feed inlet 506.

[0047] The feed inlet 506 and threaded end cap 507 structure on the top of the medicine tank 501 provide a convenient channel for adding and replenishing repair agents through the open top design. Agents can be quickly added directly from above without disassembling the medicine tank 501, making it particularly suitable for adjusting agent dosage in real time according to the repair progress during on-site operations. The threaded end cap 507 has excellent sealing performance, effectively preventing leakage or evaporation of agents due to shaking or tilting during storage, transportation, and operation. It is also easy for operators to unscrew or tighten by hand, balancing practicality and sealing. This simple and reliable structure, working in conjunction with the internal stirring system of the medicine tank 501, ensures that the agents are quickly and evenly mixed after addition. This improves operational efficiency and avoids the inconvenience of adding agents in traditional closed medicine tanks 501 or the susceptibility to contamination in open structures, ensuring a stable supply and safe use of agents during the repair process.

[0048] Further optimization of the design: the outer cover 401 is arched, which semi-encloses the throwing component 4. Several nozzles 502 pass through the outer cover 401 and are connected to branch pipes 508. The branch pipes 508 are fixed to the outside of the outer cover 401. The branch pipes 508 are connected to the main pipe 509. The main pipe 509 is connected to the bottom of the medicine tank 501, and a water pump 510 is connected to the main pipe 509.

[0049] The outer cover 401 adopts a semi-enclosed arch-shaped structure, tightly surrounding the turning and mixing component 4 to form a semi-enclosed turning space. This effectively prevents soil particles from splashing during the turning process and precisely confines the agent from the spraying component 5 within the turning area, reducing the diffusion of the agent to the surrounding environment and improving the environmental friendliness of the remediation process. The branch pipes 508 fixed to the outside of the outer cover 401 and the nozzles 502 penetrating the outer cover 401 form a distributed spraying network. Combined with the connection design between the main pipe 509 and the bottom of the tank 501 and the power drive of the water pump 510, the spraying pressure and flow rate of the agent can be flexibly adjusted according to the degree of soil pollution, so that the remediation agent is effectively sprayed within the turning and mixing roller 4. 02 When turning the soil, the agent is sprayed evenly from multiple angles into the loose soil flow. The turning action achieves dynamic mixing of the agent and soil, significantly improving the contact area and uniformity between the agent and the soil. The arch-shaped structure has strong mechanical stability and can withstand the impact force when the turning roller 402 rotates at high speed, ensuring the reliability of the equipment in long-term operation. At the same time, the external design of the branch pipe 508 facilitates installation, inspection and maintenance of the agent pipeline, and avoids interference from the internal layout to the operation of the turning component 4. The whole process realizes precise operation of "dust control, agent control and flow control" in the repair process, solving the problems of agent dispersion, low mixing efficiency and large environmental impact of traditional repair equipment.

[0050] The design was further optimized by attaching a tension bracket 6 to the front end of the mounting plate 1.

[0051] The traction bracket 6 fixed to the front end of the mounting plate 1 provides a stable force fulcrum for operators or traction machines, facilitating the movement, turning, or positioning of the equipment.
