Description

Technical Field

[0001] The present invention relates to the technical field of soil remediation, and more particularly to a soil heavy metal remediation device. Background Art

[0002] With the development of industry and the modernization of agricultural production, the problem of environmental pollution has become increasingly serious. Among them, the problem of soil heavy metal pollution is particularly prominent. Soil is one of the main natural resources on which humans depend for survival and is also an important part of the human ecological environment. However, as an open system, soil exchanges matter and energy with other elements in the environment all the time. Heavy metals enter the soil through ways such as atmospheric deposition, sewage irrigation, application of pesticides and fertilizers, and discharge of solid waste. Soil heavy metal pollution mainly refers to the phenomenon that due to human activities, solid waste, sewage or dust containing heavy metals enter the soil, resulting in the heavy metals in the soil being significantly higher than the original content and causing the deterioration of the ecological environment quality. In the prior art, the common practice of a soil remediation device is to crush the soil to increase the contact area between the soil and the air, and then add a remediation agent to the crushed soil. When the remediation liquid is sprinkled on the surface of the soil, it will be absorbed by the soil. However, in the process of crushing the soil, the common soil remediation device cannot adjust the depth of crushing, resulting in poor adaptability of the device to different soils. At the same time, when the remediation agent is directly sprayed, the soil near the bottom layer cannot contact the remediation liquid, and the heavy metals in the soil and the remediation agent cannot undergo sufficient contact reaction, resulting in uneven remediation of each position of the soil and poor remediation effect. How to invent a soil heavy metal remediation device to solve these problems has become an urgent problem for those skilled in the art. Summary of the Invention

[0003] To make up for the above deficiencies, the present invention provides a soil heavy metal remediation device, aiming to solve the problem that the common soil remediation device cannot adjust the depth of crushing during the process of crushing the soil and has a poor remediation effect.

[0004] The present invention is implemented as follows: The present invention provides a soil heavy metal remediation device, including a frame and a mounting frame arranged on the frame. One inner wall of the frame is installed with a pressure tank. A plurality of spray heads are installed on the side wall of the pressure tank. A sealing port is installed on the inner wall of the pressure tank. An air compressor is installed above the frame near the pressure tank. The output end of the air compressor is installed with an air delivery pipe communicating with the pressure tank. Symmetrical hydraulic rods are installed on the front two side walls of the frame. Front wheels and rear wheels are respectively installed on the outer walls at both ends of the frame. Two groups of symmetrical sliding grooves are opened on both side walls of the frame; One end of the mounting frame is provided with a plurality of plowshares. A roller shaft and two conveying rollers are mounted on the mounting frame. A conveyor belt is drivingly connected between the two conveying rollers. A plurality of shovel blades are mounted on the outer wall of the roller shaft. A second motor is mounted on one side outer wall of the mounting frame.

[0005] Preferably, the pressure tank is filled with a dry powder repair agent. After the dry powder is fed into the tank through the sealing port, it is sealed with a sealing cover. The two front wheels are respectively rotatably connected to both sides of the frame. A wheel shaft that is rotatably connected to the inner wall of the frame is fixedly connected between the two rear wheels.

[0006] Preferably, the upper side walls on both sides of the frame are respectively fixedly connected to the output ends of two hydraulic rods. A plurality of plowshares are fixed to the front end of the mounting frame. The two ends of the roller shaft and the conveying rollers are respectively rotatably connected to the inner wall of the mounting frame. The two ends of the two conveying rollers are respectively slidably connected to the inner walls of two groups of chutes. The output end of the second motor is fixedly connected to one end of the conveying roller. A seventh transmission wheel is mounted at one end of the conveying roller. Seventh transmission wheels are mounted at both ends of the other conveying roller. A third transmission belt is drivingly connected between the two seventh transmission wheels. A second transmission wheel is mounted at one end of the roller shaft. A second transmission belt is drivingly connected between the second transmission wheel and one of the seventh transmission wheels.

[0007] By adopting the above technical solution, before repairing the heavy metal contaminated soil, the dry powder repair agent is filled into the pressure tank through the sealing port. The height of the mounting frame outside the frame is adjusted by the hydraulic rod, so that the plowshares at the front end can be moved to an appropriate depth according to the depth of the contamination, and can be flexibly and carefully adjusted according to the actual soil texture and structure, ensuring that the best repair operation can be achieved under various soil conditions and improving the adaptability of the device to different soil environments.

[0008] Preferably, a filling component is mounted on the inner wall of the frame. The filling component includes an inclined plate fixed to the inner wall of the frame. A notch is formed between the inclined plates. An elastic cloth is mounted on the inner wall of the notch. An installation groove is formed at one end of the inclined plate. An adjusting plate is rotatably connected to the inner wall of the installation groove. A material discharging groove is formed on the adjusting plate. A support plate is mounted at one end of the adjusting plate. A support roller is rotatably connected to one end of the support plate. A sliding plate is mounted on the side of the support plate close to the material discharging groove. A baffle is mounted on the inner wall of the frame above the material discharging groove.

[0009] Preferably, the filling component further includes two crushing rollers and a stirring roller. Gears that mesh with each other are installed at one ends of the two crushing rollers. A third transmission wheel is installed at the other end of one of the crushing rollers. A fourth transmission wheel is installed at one end of the stirring roller. A fourth transmission belt is connected between the fourth transmission wheel and the third transmission wheel. A fixing frame is installed on one side of the frame. A first motor is installed on the fixing frame. The output end of the first motor is fixedly connected to one end of one of the crushing rollers.

[0010] By adopting the above technical solution, the soil sprayed with the repair agent falls between the two crushing rollers. The larger soil particles are crushed by the rotation of the crushing rollers, breaking the larger soil aggregates into smaller particles or fragments, increasing the surface area of the soil, and exposing the encapsulated heavy metals on the surface. The repair agent can come into contact with them more fully and react, improving the efficiency of the repair agent and enabling the repair reaction to proceed more comprehensively and deeply. At the same time, it effectively avoids the accumulation and blockage of the agglomerated soil, thereby improving the effect of subsequent soil laying.

[0011] Preferably, a vibration component is installed on the outer wall of the frame near the lower part of the elastic cloth. The vibration component includes a fixing block, a first rotating rod, a fixing strip, an adjusting block, a sliding rod, a guiding plate, a disc, and a connecting rod. One end of the fixing block is fixedly connected to the outer wall of the elastic cloth. Sliding blocks that are slidably connected to the inner wall of the frame are installed on both outer walls of the fixing block. A limiting strip is installed on one side of the fixing block. The two ends of the fixing strip are fixedly connected to the inner wall of the frame. A first rotating groove is opened on one side of the fixing block. Both ends of the first rotating rod are installed with first rotating shafts that rotate with the inner wall of the first rotating groove. A first torsion spring is sleeved on the outer part of the first rotating shaft. Both side walls of the first torsion spring are fixedly connected to the first rotating groove and one end of the first rotating rod respectively.

[0012] Preferably, a second rotating groove is opened on one side of the adjusting block. A second rotating rod is rotatably connected to the inner wall of the second rotating groove. Both ends of the second rotating rod are installed with second rotating shafts that are rotatably connected to the inner wall of the second rotating groove. A second torsion spring is sleeved on the outer part of the second rotating shaft. Both side walls of the second torsion spring are fixedly connected to one side inner wall of the second rotating groove and one end of the second rotating shaft respectively. Limiting plates for limiting the second rotating rod are installed on both side walls of the adjusting block.

[0013] Preferably, both ends of the guiding plate are fixedly connected to the inner wall of the frame. A plurality of sliding rods are fixed to the bottom end of the adjusting block. The outer wall of the sliding rod is slidably connected to the inner wall of the guiding plate. An eccentric shaft that is rotatably connected to the inner wall of one end of the connecting rod is fixedly connected between the two discs. The other end of the connecting rod is rotatably connected to one end of the sliding rod.

[0014] Preferably, a connecting shaft is installed at one end of the disc away from the eccentric shaft. A plurality of the connecting shafts connect the discs into a whole. Both ends of the connecting shaft are rotatably connected to the inner wall of the frame. A fifth transmission wheel and a sixth transmission wheel are respectively installed on the side wall of one end of the connecting shaft. A fifth transmission belt is connected between the fifth transmission wheel and the fourth transmission wheel. A first transmission wheel is installed on the side wall of one end of the wheel shaft. A sixth transmission belt is connected between the first transmission wheel and the sixth transmission wheel.

[0015] It should be noted that during the operation of the device, the connecting shaft drives the disc to rotate. The eccentric shaft cooperates with the connecting rod to make the adjusting block at the upper end of the sliding rod slide reciprocally. Initially, the second rotating rod on the inner wall of the adjusting block abuts against the first rotating rod. As the adjusting block moves downward, it drives the fixed block on one side to move downward. During the downward movement, one side of the elastic cloth is pulled downward to deform. The fixed block rebounds rapidly under the restoring force of the elastic cloth, thereby realizing the vibration of the soil above the elastic cloth, breaking the possible aggregates formed, and making the repair agent more evenly dispersed in the soil.

[0016] The beneficial effects of the present invention are as follows: The hydraulic rod and the mounting frame are arranged to break the soil at different depths, and can be flexibly adjusted according to the actual soil texture and structure, ensuring the best repair operation under various soil conditions, improving the adaptability of the device to different soil environments. The nozzle and the soil falling by gravity are arranged to ensure uniform mixing with the repair agent, enabling the repair agent to fully contact the heavy metals in the soil. No matter how the heavy metals are distributed on the surface of soil particles, in pores or at different depths, there is a chance to react with the repair agent, improving the repair effect; The filling component repairs the soil and at the same time fills the pit of the repaired soil, reducing the operation steps, enabling the repair work to be promoted more efficiently, accelerating the progress of the entire soil repair project, and reducing the labor cost and time cost; The vibration component continuously vibrates the soil during the backfilling and conveying process of the soil, causing relative movement between the soil particles and the repair agent particles, breaking the possible aggregates formed, making the repair agent more evenly dispersed in the soil. At the same time, the continuous shaking can prevent the soil from being overly compacted during the mixing process of the repair agent, providing a more favorable physical environment for the movement and action of the repair agent in the soil, enabling the repair agent to penetrate and diffuse more smoothly in the soil, and improving the uniformity and depth of the repair.

[0020] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Example 1, referring to Figures 1-6, A soil heavy metal remediation device, comprising a frame 1 and a mounting frame 2 provided on the frame 1. One inner wall of the frame 1 is installed with a pressure tank 11. A plurality of spray nozzles 111 are installed on the side wall of the pressure tank 11. A sealing port 112 is installed on the inner wall of the pressure tank 11. An air compressor 12 is installed above the frame 1 near the pressure tank 11. The output end of the air compressor 12 is installed with an air delivery pipe 121 communicating with the pressure tank 11. Symmetric hydraulic rods 13 are installed on both front side walls of the frame 1. Front wheels 14 and rear wheels 15 are respectively installed on the outer walls at both ends of the frame 1. Two symmetric groups of sliding grooves 16 are provided on both side walls of the frame 1; One end of the mounting frame 2 is installed with a plurality of plowshares 21. A roller shaft 22 and two conveying rollers 23 are installed on the mounting frame 2. A conveyor belt 25 is drivingly connected between the two conveying rollers 23. A plurality of shovel blades 222 are installed on the outer wall of the roller shaft 22. A second motor 26 is installed on one outer wall of the mounting frame 2.

[0022] Furthermore; the pressure tank 11 is filled with a dry powder remediation agent. After the dry powder is fed through the sealing port 112, it is sealed with a sealing cover. The two front wheels 14 are respectively rotatably connected to both sides of the frame 1. A wheel shaft 151 rotatably connected to the inner wall of the frame 1 is fixedly connected between the two rear wheels 15. The upper side walls on both sides of the frame 1 are respectively fixedly connected to the output ends of the two hydraulic rods 13. The plurality of plowshares 21 are fixed to the front end of the mounting frame 2. The two ends of the roller shaft 22 and the conveying rollers 23 are respectively rotatably connected to the inner wall of the mounting frame 2. The two ends of the two conveying rollers 23 are respectively slidably connected to the inner walls of the two groups of sliding grooves 16. The output end of the second motor 26 is fixedly connected to one end of the conveying roller 23. A seventh transmission wheel 231 is installed at one end of this conveying roller 23. Seventh transmission wheels 231 are installed at both ends of the other conveying roller 23. A third transmission belt 27 is drivingly connected between the two seventh transmission wheels 231. A second transmission wheel 221 is installed at one end of the roller shaft 22. A second transmission belt 24 is drivingly connected between the second transmission wheel 221 and one of the seventh transmission wheels 231.

[0023] It should be noted that: before repairing the heavy metal - contaminated soil, the dry - powder repair agent is filled into the pressure tank 11 through the sealing port 112. The height of the mounting frame 2 outside the frame 1 is adjusted by the hydraulic rod 13, so that the plowshare 21 at the front end is moved to an appropriate depth according to the depth of the pollution. It can be carefully adjusted flexibly according to the actual soil texture and structure to ensure the best repair operation under various soil conditions, improve the adaptability of the device to different soil environments. Then, the second motor 26 is started to drive the roller shaft 22 to drive the outer shovel blade 222 to rotate. The shovel blade 222 flips the broken soil and throws it onto the rear conveyor belt 25, and the conveyor belt 25 transports it upward until it reaches the highest point and then scatters under the action of gravity. During this process, the air compressor 12 is started to supply air to the pressure tank 11, increasing the internal air pressure so that the repair agent contacts the falling soil through the nozzle 111, ensuring that the soil and the repair agent are evenly mixed, enabling the repair agent to fully contact the heavy metals in the soil. Regardless of the distribution of heavy metals on the surface of soil particles, in pores or at different depths, there is a chance to react with the repair agent, improving the repair effect.

[0024] Example 2, please refer to Figures 7-8 , on the basis of Example 1, to save the time for backfilling the repaired soil later; Furthermore; a filling component 3 is installed on the inner wall of the frame 1. The filling component 3 includes an inclined plate 31 fixed to the inner wall of the frame 1. A notch 312 is formed between the inclined plates 31. An elastic cloth 313 is installed on the inner wall of the notch 312. An installation groove 311 is formed at one end of the inclined plate 31. A regulating plate 33 is rotatably connected to the inner wall of the installation groove 311. A blanking groove 331 is formed on the regulating plate 33. One end of the regulating plate 33 is provided with a support plate 34. One end of the support plate 34 is rotatably connected to a support roller 341. A sliding plate 35 is installed on the side of the support plate 34 close to the blanking groove 331. A baffle 32 is installed on the upper inner wall of the frame 1 close to the blanking groove 331. The filling component 3 further includes two crushing rollers 36 and a stirring roller 37. Meshing gears 361 are installed at one ends of the two crushing rollers 36. A third transmission wheel 362 is installed at the other end of one of the crushing rollers 36. A fourth transmission wheel 371 is installed at one end of the stirring roller 37. A fourth transmission belt 38 is connected between the fourth transmission wheel 371 and the third transmission wheel 362. A fixing frame 17 is installed on one side of the frame 1. A first motor 171 is installed on the fixing frame 17. The output end of the first motor 171 is fixedly connected to one end of one of the crushing rollers 36; It should be noted that: The soil sprayed with the repair agent falls between the two crushing rollers 36. The rotation of the crushing rollers 36 crushes the soil with larger particles, decomposes the larger soil aggregates into smaller particles or fragments, increases the surface area of the soil, exposes the encapsulated heavy metals on the surface, enables the repair agent to come into contact with them more fully and react, improves the efficiency of the repair agent, allows the repair reaction to proceed more comprehensively and deeply, and effectively avoids the accumulation and blockage between the agglomerated soils, thereby improving the effect of subsequent soil laying. The crushed soil reaches above the adjusting plate 33 under the action of gravity. At the same time, the rotating stirring roller 37 further stirs the soil to improve the mixing effect of the repair agent and the soil and ensure the uniform distribution of the repair agent; After that, as the device moves, the supporting roller 341 at one end of the supporting plate 34 contacts the ground and rotates. When the supporting roller 341 reaches the repaired pit, it disengages from the ground. At this time, the adjusting plate 33 rotates under the action of the gravity of the soil, so that the outer wall of the supporting roller 341 abuts against the pit. Under the dual action of the stirring roller 37 and gravity, the soil slides down along the adjusting plate 33, and is guided by the baffle 32 and the feeding chute 331 to flow downward into the pit passed by the supporting roller 341, filling the pit with the soil filled with the repair agent. While repairing the soil, the repaired soil is returned to the pit, reducing the operation steps, enabling the repair work to be promoted more efficiently, accelerating the progress of the entire soil repair project, and reducing the labor cost and time cost.

[0025] Example 3, please refer to Figures 9-14 On the basis of Example 1, in order to further improve the uniformity of the mixture of the soil and the repair agent and ensure the repair effect of the soil; Further, a vibration assembly 4 is installed near the lower outer wall of the elastic cloth 313 of the frame 1. The vibration assembly 4 includes a fixed block 41, a first rotating rod 42, a fixed strip 43, an adjusting block 44, a sliding rod 45, a guide plate 46, a disc 47 and a connecting rod 48. One end of the fixed block 41 is fixedly connected to the outer wall of the elastic cloth 313. Sliders that are slidably connected to the inner wall of the frame 1 are installed on both outer walls of the fixed block 41. A limiting strip 411 is installed on one side of the fixed block 41. Both ends of the fixed strip 43 are fixedly connected to the inner wall of the frame 1. A first rotating groove 412 is formed on one side of the fixed block 41. First rotating shafts 421 that are rotatably connected to the inner wall of the first rotating groove 412 are installed at both ends of the first rotating rod 42. A first torsion spring 413 is sleeved on the outer part of the first rotating shaft 421. Both side walls of the first torsion spring 413 are fixedly connected to the first rotating groove 412 and one end of the first rotating rod 42 respectively. A second rotating groove 442 is formed on one side of the adjusting block 44. A second rotating rod 444 is rotatably connected to the inner wall of the second rotating groove 442. Second rotating shafts 445 that are rotatably connected to the inner wall of the second rotating groove 442 are installed at both ends of the second rotating rod 444. A second torsion spring 443 is sleeved on the outer part of the second rotating shaft 445. Both side walls of the second torsion spring 443 are fixedly connected to one side inner wall of the second rotating groove 442 and one end of the second rotating shaft 445 respectively. Limiting plates 441 for limiting the second rotating rod 444 are installed on both side walls of the adjusting block 44. Both ends of the guide plate 46 are fixedly connected to the inner wall of the frame 1. A plurality of sliding rods 45 are fixed to the bottom end of the adjusting block 44. The outer wall of the sliding rod 45 is slidably connected to the inner wall of the guide plate 46. An eccentric shaft 471 that is rotatably connected to the inner wall of one end of the connecting rod 48 is fixedly connected between two discs 47. The other end of the connecting rod 48 is rotatably connected to one end of the sliding rod 45. A connecting shaft 472 is installed at one end of the disc 47 away from the eccentric shaft 471. A plurality of connecting shafts 472 connect the discs 47 into a whole. Both ends of the connecting shaft 472 are rotatably connected to the inner wall of the frame 1. A fifth driving wheel 473 and a sixth driving wheel 474 are installed on both side walls of one end of the connecting shaft 472 respectively. A fifth driving belt 5 is connected between the fifth driving wheel 473 and the fourth driving wheel 371. A first driving wheel 152 is installed on both side walls of one end of the wheel shaft 151. A sixth driving belt 6 is connected between the first driving wheel 152 and the sixth driving wheel 474; It should be noted that there is an elastic cloth 313 in the middle part of the inclined plate 31. During the operation of the device, the connecting shaft 472 drives the disc 47 to rotate. At the same time, the eccentric shaft 471 between two adjacent discs 47 rotates. During the rotation, the connecting rod 48 is cooperated to make the slide rod 45 at one end reciprocate and slide on the inner wall of the guide plate 46. At the same time, the adjusting block 44 at the upper end of the slide rod 45 reciprocates. Initially, the second rotating rod 444 on the inner wall of the adjusting block 44 abuts against the first rotating rod 42. As the adjusting block 44 moves downward, it drives the fixed block 41 on one side to move downward. During the downward movement, it pulls one side of the elastic cloth 313 to deform downward until the limiting strip 411 on one side of the fixed block 41 contacts the lower fixed strip 43. At this time, the adjusting block 44 continues to move downward and squeezes the first rotating rod 42 through the second rotating rod 444, causing the first rotating rod 42 to twist the first torsion spring 413 and rotate. At the same time, the second rotating rod 444 remains fixed under the action of the limiting plate 441 until the first rotating rod 42 rotates 90 degrees and is parallel to the second rotating rod 444 at this time. At the same time, the fixed block 41 quickly rebounds under the restoring force of the elastic cloth 313, thereby realizing the vibration of the soil above the elastic cloth 313. And in the subsequent process when the second rotating rod 444 rises and contacts the first rotating rod 42, the first rotating rod 42 remains fixed. At the same time, the second rotating rod 444 twists the second torsion spring 443 and rotates, and its side wall abuts against the first rotating rod 42 to rise until the second rotating rod 444 reaches above the first rotating rod 42. At this time, the above movement is continued. When the fixed block 41 is pulled to the lowest end and then released and rebounds, the vibration of the soil is continuously realized, so that relative movement is generated between the soil particles and the repair agent particles, the possible aggregates are broken, and the repair agent is more evenly dispersed in the soil. At the same time, the continuous shaking can prevent the soil from being overly compacted during the mixing process of the repair agent, providing a more favorable physical environment for the movement and action of the repair agent in the soil, enabling the repair agent to penetrate and diffuse more smoothly in the soil, and improving the uniformity and depth of the repair.

[0026] It should be noted that the specific model and specification of the motor need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail here.

For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
