Description

Technical Field

[0001] The present invention relates to the technical field of soil pollution prevention and control, and in particular to a pollution prevention and control treatment device for soil. Background Art

[0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants, mainly including acids, alkalis, heavy metals, salts, compounds containing arsenic, selenium, and fluorine, organic pesticides, phenols, urban sewage, harmful microorganisms, etc. Soil pollution prevention and control can be divided into in-situ remediation and ex-situ remediation. Both pollution prevention and control methods require corresponding equipment. A Chinese patent discloses a soil remediation device for contaminated soil, application number: 202321939606.2, which reduces the production cost of the inflow device;

[0003] However, current pollution prevention and control equipment often only performs simple spraying of treatment agents during in-situ soil remediation. The treatment agents are often enriched and accumulated on the soil surface and cannot effectively penetrate into the deep soil. In addition, the rate of treatment agent delivery is not synchronously compatible with the travel speed of the equipment. Fluctuations in the travel speed of the equipment can easily cause drastic fluctuations in the unit treatment dosage of the soil in various places, making it impossible to effectively utilize the treatment agents. This not only results in a waste of treatment agents, but can also easily further increase the local soil burden and cause pollution to worsen. Summary of the invention

[0023] Compared with the prior art, the invention has the following beneficial effects: the invention has a scientific and reasonable structure and is safe and convenient to use;

[0024] 1. A deep-layer processing mechanism is provided. Through the cooperation of the liquid tank, push plate, connecting rod, outer ring, deflection plate and disc, a driving force conversion structure can be constructed, which can perform dual conversion and utilization of external traction, effectively enhancing the effective utilization rate and utilization effect of external traction. On the one hand, it can cooperate with the liquid outlet pipe, wheel box, guide groove, wheel, liquid return pipe and diversion valve to perform preliminary conversion and utilization of traction. In the process of the equipment moving forward, the curved blade is driven to synchronously plow and crush the soil, which greatly improves the coordination between the equipment's travel speed and the soil crushing rate. It not only effectively enhances the effectiveness of soil crushing work, but also makes the soil crushing work more balanced. It can effectively avoid the soil crushing blind area, make the soil crushing more sufficient, and provide more suitable preconditions for the delivery of the treatment agent, which can greatly enhance the convenience and stability of the treatment agent delivery, so that the treatment agent can play a more full role.

[0025] On the other hand, it can cooperate with bent rods, screws, bases, sleeves, rotating rods, tail boxes, plugs, long rods and collars to perform secondary conversion and utilization of traction. In addition, the flow limiting and guiding functions of the check valve, feed pipe, barrel and discharge pipe can realize the synchronous injection and spraying of the treatment agent after soil crushing, and can simultaneously inject the treatment agent into deep soil to achieve deep treatment and repair of the soil. While improving the compatibility and adaptability between the equipment's travel work, soil crushing work and treatment agent delivery work, the spraying and injection of the treatment agent can be made more uniform, effectively enhancing the penetration and combination efficiency of the treatment agent and the soil, and avoiding the treatment agent from escaping into the air. While improving environmental friendliness, it also improves the effective utilization rate of the treatment agent, so that the treatment agent can play a more efficient and stable role. At the same time, through the cooperation of the screw, base and sleeve, the unit injection volume of the treatment agent can be conveniently regulated, and the amount of the treatment agent can be flexibly controlled according to actual needs, further improving the flexibility of the equipment and making the equipment's treatment work more flexible and efficient.

[0026] 2. A balanced lifting mechanism is provided. Through the cooperation of the strip plate, hollow gear, vertical shaft, driven wheel and driving wheel, an adaptive conversion structure of driving force can be constructed, which can further dynamically convert the external traction force. On the one hand, it can cooperate with the bottom shaft, linkage gear, steering gear, tooth chain and stirring head to form a synchronous stirring structure, which can synchronously stir the treatment agent inside the material box during the operation of the equipment, so that the various components inside the treatment agent can be mixed more fully and the uniformity of the treatment agent can be improved. On the other hand, it can effectively avoid the deposition of effective components inside the treatment agent, fully ensure the balance of the effective components inside the sprayed treatment agent during the entire soil pollution prevention and control process, ensure the balance and effectiveness of the treatment agent on the soil at various locations, so that the treatment of polluted soil at various locations can be carried out stably and orderly, and the pollution treatment of soil can be more efficient and stable;

[0027] By cooperating with cylinders, circular plates, connecting rods, conduits, pressure gauges, air valves and poles, an elastic support structure can be constructed, which can provide the curved blade with stable elastic support pressure, making the curved blade work more efficiently. In addition, the adjustment function of the adjustment box, piston plate and threaded rod can, on the one hand, conveniently control the cutting depth and make the cutter fit the soil better, thereby improving the tillage and crushing effect of the soil and making the soil crushing depth more uniform before and after, further enhancing the penetration uniformity after the treatment agent is added, and improving the treatment effect of contaminated soil. On the other hand, while providing stable support to the curved blade, it can also provide it with sufficient buffer space, which can effectively prevent it from being damaged by hard collision with hard materials, effectively improve the durability of the equipment, and increase the effective service life of the equipment. By cooperating with the disc and the ground-smoothing roller, the soil after tillage and crushing can be smoothed, effectively preventing the treatment agent from escaping into the air, while improving environmental protection, further enhancing the effective utilization rate of the treatment agent.

[0028] To sum up, this equipment can simultaneously take into account the equipment's movement and repositioning, soil plowing and crushing, and the placement of treatment agents during the on-site prevention and control treatment of contaminated soil, making the connection between various tasks more stable and efficient, more compatible and adaptable, effectively preventing the treatment agent from escaping into the air, improving the uniformity and consistency of the placement of the treatment agent, achieving rapid prevention and control and remediation of deep soil, effectively improving the effectiveness and efficiency of soil treatment and remediation, and improving the treatment effect.

[0053] Working principle and use process of the present invention: When the pollution prevention and treatment equipment for soil is actually used, the equipment is first transported to the working area, and the main frame 1 is connected to the tractor. Here, other traction mechanisms can also be replaced according to actual conditions. For the convenience of description below, the default traction mechanism is a tractor. Then, according to actual needs, that is, according to the pollution status of the soil, an appropriate chemical or biological agent is selected, and an appropriate amount of chemical or biological agent solution is injected into the material box 7. For the convenience of description below, the treatment agent refers to the chemical or biological agent solution injected into the material box 7;

[0054] Next, air is injected into the cylinder 311 through the air valve 319, and the air pressure inside the cylinder 311 is controlled according to the reading of the barometer 318, so as to provide stable elastic support to the top of the circular plate 312, compensate for the adhesion force between the scimitar 6 and the soil, and enable the scimitar 6 to obtain stable cutting stress. Here, the pressure on the top of the circular plate 312 should be limited according to the hardness of the soil, and the pressure at which the scimitar 6 can just be inserted into the soil under the action of this pressure is the optimal pressure. To ensure the effectiveness of the scimitar 6, the pressure on the top of the circular plate 312 should not be less than the optimal pressure. At the same time, the pressure should be limited according to the compressive strength of the scimitar 6, and the pressure should be less than the upper limit of the bearing pressure of the scimitar 6, so as to ensure that the scimitar 6 can cut stably and overcome the top pressure and rise to avoid when cutting too hard a material.

[0055] At the same time, the cutting depth of the scimitar 6 can be synchronously adjusted by rotating the threaded rod 317. When the threaded rod 317 rotates clockwise, the two piston plates 316 will move away from each other, which will squeeze the hydraulic fluid inside the adjustment box 315 and press the hydraulic fluid into the cylinder 311 through the conduit 314, forcing the circular plate 312 to rise under the pressure of the hydraulic fluid and overcome the top air pressure. Conversely, when the threaded rod 317 rotates counterclockwise, the two piston plates 316 will move toward each other, and the hydraulic fluid inside the cylinder 311 will be drawn into the adjustment box 315 through the conduit 314. After the circular plate 312 loses the bottom hydraulic support, it will drop accordingly under the action of the top air pressure.

[0056] During the lifting and lowering process of the circular plate 312, it will drive the sub-frame 2 to rise and fall synchronously through the connecting rod 313, so that the scimitar 6 installed on the sub-frame 2 rises and falls synchronously. In this process, the benchmark 320 will also rise and fall synchronously with the circular plate 312. When the top of the benchmark 320 is flush with the cylinder 311, the bottom of the outer curved surface of the knife shaft 5 is just flush with the bottom of the outer curved surface of the hub 4. At this time, the cutting depth of the scimitar 6 is equal to the distance from its tip to the knife shaft 5. This cutting depth is the initial depth. The initial depth minus the rising height of the scimitar 6 in the aforementioned process, that is, minus the rising height of the benchmark 320, is the actual cutting depth. According to the indication of the benchmark 320, the cutting depth of the scimitar 6 can be limited and adjusted. After adjusting the actual cutting depth, the pressure on the top of the circular plate 312 should be fine-tuned for a second time by filling and discharging air through the air valve 319 according to the indication of the barometer 318, so that the pressure value is kept within the aforementioned required range to improve the cutting stability.

[0057] Then, the screw rod 214 is rotated to drive the base 215 to rise and fall, so that the sleeve 216 is synchronously lifted and lowered along the rotating rod 217 driven by the base 215, and the position of the support point given by the sleeve 216 to the rotating rod 217 is changed. During the operation of the equipment, a lever structure is formed between the bent rod 213, the sleeve 216 and the collar 221. The closer the sleeve 216 is to the collar 221, the shorter the reciprocating displacement process of the long rod 220 driven by the collar 221 during the deflection of the bent rod 213. According to the actual situation, that is, the degree of soil contamination, the reciprocating displacement range of the plug 219 inside the tail box 218 during the operation of the equipment can be limited, so as to limit the unit spraying amount of the treatment agent according to actual needs;

[0058] After completing the above-mentioned adjustment work, the equipment can be towed by a tractor to carry out soil pollution prevention and control work. Driven by the tractor, the wheel hub 4 rotates with the displacement of the main frame 1, so that the disc 206 drives the deflection disc 205 to rotate synchronously under the drive of the wheel shaft 3, forcing the outer ring 204 to drive the push plate 202 to reciprocate and rise and fall inside the liquid tank 201 through the connecting rod 203 under the drive of the deflection disc 205, and then under the flow limiting guidance of the guide valve 212, during the lifting and lowering process of the push plate 202, it will hydraulically pressurize the internal hydraulic pressure of the liquid tank 201 into the liquid outlet pipe 207, and send it into the wheel box 208 through the guide groove 209, impact the inclined surface of the runner 210, drive the runner 210 to rotate in the wheel box 208, and then the hydraulic fluid will enter the return pipe 211, and during the lifting and lowering process of the push plate 202, it will be pumped into the liquid tank 201, realizing the closed-loop circulation of the hydraulic fluid;

[0059] During this process, as the rotating wheel 210 rotates, on the one hand, it will drag the blade shaft 5 to rotate synchronously, and the curved blade 6 will be embedded in the ground under the pressure exerted by the circular plate 312. As the blade shaft 5 rotates, the curved blade 6 will plow and crush the soil. On the other hand, it will drive the curved rod 213 to rotate synchronously, forcing the rotating rod 217 to reciprocate around the sleeve 216 under the drive of the curved rod 213, so that the long rod 220, under the drag of the collar 221, drives the plug 219 to move back and forth inside the tail box 218;

[0060] Under the flow limiting guidance of the check valve 222, as the plug 219 moves back and forth inside the tail box 218, the treatment agent inside the material box 7 will be drawn into the tail box 218 through the feeding pipe 223 connected thereto, and then sent into the barrel 224 through another feeding pipe 223. Under the guidance of the barrel 224, the treatment agent will evenly enter each discharge pipe 225 and be discharged through the holes on the back side of the discharge pipe 225. Then, during the forward movement of the tractor traction equipment and the process of tilling and crushing the soil, the treatment agent will be synchronously injected into the soil, which can improve the convenience while making the spraying of the treatment agent more balanced, speeding up the penetration rate of the treatment agent, making the treatment agent more fully infiltrated into the soil, reducing the loss of the treatment agent, and deepening the treatment effect.

[0061] Also in this process, as the wheel hub 4 rotates, the driving wheel 305 will drive the vertical shaft 303 to rotate synchronously through the driven wheel 304, forcing the hollow gear 302 to drive the steering gear 308 to rotate synchronously through the toothed chain 309 under the drive of the vertical shaft 303, and under the transmission of each linkage gear 307 and the toothed chain 309, each bottom shaft 306 drives the stirring head 310 to rotate inside the material box 7, stirring the treatment agent inside the material box 7, avoiding the deposition of the effective components in the treatment agent, making the effective components carried by the sprayed treatment agent more balanced, and improving the effectiveness of pollution treatment and remediation;

[0062] It should be added that: in the process of adjusting the cutting depth of the curved blade 6, the strip 301 will rise and fall synchronously with the sub-frame 2, thereby ensuring that the hollow gear 302, the linkage gear 307 and the steering gear 308 are always on the same horizontal plane without affecting the transmission efficiency of the vertical shaft 303, the driven wheel 304 and the driving wheel 305, ensuring the driving stability of the mixing head 310, and taking into account the soil plowing and crushing work, the treatment agent injection work and the treatment agent mixing work at the same time;

[0063] After the soil is plowed and broken, before the treatment agent is injected into the soil, as the equipment moves forward, the wheel 321 and the smoothing roller 322 will roll accordingly. During the rolling process of the smoothing roller 322, it will smooth the plowed and broken soil, thereby ensuring the uniformity of the soil before the treatment agent is injected into the soil through the discharge pipe 225, avoiding the treatment agent from being sprayed into the air and escaping, and improving the effective utilization rate of the treatment agent. After completing the soil treatment work, the threaded rod 317 can be further rotated clockwise to lift the sub-frame 2, so that the curved blade 6 is separated from the ground, and the equipment can be transported for the next round of soil treatment work.
