Description

Technical Field

[0001] This invention belongs to the field of soil remediation technology, and specifically relates to a mobile, rapid, on-site emergency remediation and reuse device for contaminated soil. Background Technology

[0002] Currently, mobile contaminated soil remediation equipment has become the core equipment for emergency remediation and decentralized pollution control due to its advantages of on-site operation and rapid response. However, most equipment generally lacks effective pre-treatment and screening of soil clods and stones mixed in the soil before transporting it after loosening. This can easily cause serious blockage of the conveying mechanism. In addition, some equipment combines crushing and screening processes simultaneously, which not only subject the screening mechanism to excessive vibration load, but also makes it easy for stones with a similar size to the screen hole to be hammered into the screen hole, causing screen blockage and resulting in a decrease in remediation quality and compliance rate.

[0003] A search revealed that the prior art, patent number CN 116586417 A, describes a method for in-situ remediation of soil contaminated by a chemical plant, comprising the following steps: S1. Excavation of contaminated soil: The contaminated soil is excavated from the chemical contamination area requiring remediation, and then mixed with quicklime to transform the contaminated soil from lumps into granules; S2. Soil filtration: The granular soil obtained above is preliminarily sieved using a drum screen to remove impurities from the mixture of contaminated soil and quicklime, removing impurities with a diameter exceeding 5 cm, and then set aside for later use. As is known from this prior art, adding quicklime to contaminated soil causes a chemical reaction that promotes the breaking down and dispersion of lumpy soil, making it easier to form granules.

[0004] Further search revealed existing technology announcement number CN117655077A: a mobile contaminated soil remediation equipment and its usage method, comprising: a support base with a through groove, a filter box installed above the through groove, the filter box having an inclined structure, the filter box being densely covered with sieve holes, multiple elastic elements fixedly connected between the filter box and the support base, a first motor fixedly installed on the filter box, a counterweight fixedly sleeved on the connecting shaft, and a spraying device fixedly installed on the other side of the support base; this existing technology does not screen soil clods and stones before the soil enters the soil inlet hopper, and after the soil is loosened by the turning shovel, the soil clods and stones are removed. Containing a large amount of soil clods and stones, some of which exceed the conveying radius of the auger blades, causing some soil clods and stones to accumulate in the feed hopper and blockage the hopper, seriously affecting the continuity and efficiency of soil remediation operations. Furthermore, the existing technology involves crushing and screening simultaneously within the filter box, which not only increases the pressure on the vibrating element of the filter box but also makes it easy for the loosening component to hammer stones of similar size to the sieve holes into the sieve holes, causing sieve blockage and damaging the vibration screening effect of the filter box. This prevents fine soil particles that meet the remediation requirements from falling smoothly, ultimately reducing the quality and compliance rate of remediation of contaminated soil.

[0005] A further search revealed that the prior art, patent number CN223056077U, describes a soil screening device for soil remediation, comprising a soil screening mechanism. This mechanism includes a processing vehicle with drive wheels mounted on its bottom and a battery installed inside. A screening control panel is mounted on the surface of the vehicle. A moving handle is fixedly connected to one side of the vehicle, and a soil feeding assembly is fixedly installed on the other side. A discharge guide box is fixedly connected to the top of the vehicle, and a discharge chute is provided on the inner side. This prior art also fails to screen soil clods and stones before they enter the hopper. After the hopper loosens the soil, it contains a significant amount of clods and stones, some exceeding the conveying radius of the auger blades. This causes clods and stones to accumulate in the hopper, leading to blockages and severely impacting the continuity and efficiency of soil remediation operations. Summary of the Invention

[0024] The advantages of this invention compared to existing technologies are as follows:

[0025] 1) Soil is divided by the guide hood and flows to both sides of the collection bin towards the conveyor rollers. Smaller soil particles fall into the lower collection bin through the gaps between the conveyor rollers, while larger stones and clods are sent to the stone transport bin by the conveyor rollers and then transported to the collection box by the conveyor belt. When the clods are transported to the bottom of the impact head, motor IX drives the rotating shaft V to rotate. The turntable pulls the lifting seat up and down along the fixed seat V through the connecting rod II, so that the impact head is inserted into the clod. Motor X in the lifting seat drives the rotating rod II to rotate, which drives the impact head to reciprocate at high frequency through the connecting rod III. Spring II cooperates to buffer and reset, so that the impact head vibrates at high frequency in the clod like the head of an electric pick, which accelerates the crushing speed of the clod. This achieves efficient separation of soil from clods and stones and rapid crushing of clods, avoiding blockage of the transport mechanism. The impact head quickly crushes clods by a combination of insertion and high-frequency vibration, which can quickly crush large clods into small particles, resulting in high crushing efficiency.

[0026] 2) Motor IV drives rotating shaft II to rotate, which in turn drives two sets of rotating rods I to rotate synchronously. This causes sliding plate II and sliding shell to slide along the S-shaped slide rail. The rotating sleeve on the bolt rolls within the S-shaped slide rail. While sliding plate II and sliding shell slide along the S-shaped slide rail, motor V drives the crushing roller to rotate. The crushing roller and rotating roller rotate synchronously. Motor VI drives the electric push rod to rotate. The telescopic end of the electric push rod pushes the crushing blade to cut and crush the clumps on the soil surface. The hydraulic cylinder III on the rotating roller drives the flipping plate to swing up and down via the swing rod. The S-shaped slide rail provides an arc-shaped movement path, allowing the connected crushing roller and rotating roller to flexibly adjust their working position and angle along the arc trajectory. This adapts to the soil crushing needs of different depths and different degrees of clumps, avoiding the problem of limited adjustment range of traditional linear slide rails. The crushing blade cuts the clumps, and the flipping plate turns the bottom soil to the surface, ensuring uniform crushing and sufficient reaction between quicklime and soil. This improves the soil improvement effect and crushing efficiency, avoiding the problems of limited adjustment and uneven mixing of traditional equipment.

[0027] 3) Soil is guided to the conveyor rollers via a guide hood, small soil particles are screened out and enter the collection bin. The impact head rapidly crushes large soil clods through a combination of insertion and high-frequency vibration. Stones are then conveyed to the stone collection bin by the conveyor rollers and collected by the conveyor belt into the collection box. This achieves complete interception of impurities within the radius of the super auger blades, preventing blockage of the material collection bin at the source and solving the problem of easy accumulation and jamming in the feeding stage of existing equipment. Secondly, the soil crushing and screening device adopts a clearly defined "crushing-screening" zone design. The soil turning and crushing mechanism first adjusts the operating angle and position in the crushing zone via an S-shaped slide rail, and is equipped with... The retractable crushing blades cut through clumps, and the turning plate turns over the bottom soil to achieve uniform soil crushing. Quicklime is added simultaneously to improve the compaction of soil clumps. The isolation mechanism is precisely opened after crushing. Under the guidance of the turning plate, the soil slowly enters the screening area in batches. The screening mechanism achieves high-frequency vibration of the screen by driving the eccentric wheel with a motor. The telescopic rod and spring buffer avoid bumps. Unqualified impurities are discharged into the collection bin through vibration. The hydraulic cylinder IV can push the screen frame to clean up the residue, completely avoiding the problem of screen hole blockage caused by crushing and screening in the same process, ensuring screening efficiency and soil purity.

[0028] 4) The pre-treated soil falls from the discharge port of the transport mechanism into the soil crushing and screening device below, which further crushes the small soil clods into uniform particle size. The finely screened soil to be remediated is then spread back onto the land. At this time, the chemical mixing device discharges the uniformly mixed remediation agent through the discharge port. The agent is mixed with the soil to be remediated while it is being spread back onto the land, thus achieving rapid on-site remediation and reuse of contaminated soil. Attached Figure Description

[0056] To facilitate understanding by those skilled in the art, the following is a detailed explanation in conjunction with the appendix. Figure 1-24 The technical solution of the present invention will be further described in detail below.

[0057] A mobile, rapid, on-site emergency remediation and reuse device for contaminated soil includes a carrier 1, an adjustment mechanism 2, a soil turning mechanism 3, a transport mechanism 4, a soil crushing and stone removal mechanism 5, a soil crushing and screening device 6, and a reagent mixing device 7. The carrier 1 is equipped with a hydraulic station, a hydraulic solenoid valve, a diesel generator, and a battery. The hydraulic station provides hydraulic power to the entire device, and the diesel generator and battery provide electricity to the entire device. The carrier 1 is equipped with an installation platform 101, with an adjustment port 102 at one end. The adjustment mechanism 2 is installed on one side of the adjustment port 102. The soil turning mechanism 3 and the transport mechanism 4 are installed on the adjustment mechanism 2. The soil crushing and stone removal mechanism 5 is installed on top of the transport mechanism 4. The soil crushing and screening device 6 is installed on the installation platform 101 and located on one side of the discharge port of the transport mechanism 4. The reagent mixing device 7 is installed on the installation platform 101.

[0058] The agent mixing device 7 is provided with an inlet at the top and an outlet at the bottom. The outlet passes through the bottom of the mounting platform 101 and is located on one side of the soil crushing and screening device 6.

[0059] As described above: the carrier 1 moves the entire structure to the contaminated soil area, and the regulating mechanism 2 first moves through the regulating port 102. The soil turning mechanism 3 adjusts its entry angle and depth, loosening and stripping the surface and deep contaminated soil in stages. Simultaneously, the turned-out soil is transported to the transport mechanism 4 on the same side, which then conveys the loosened soil upwards to the soil crushing and screening device 6. During soil transport, the soil clod crushing and stone removal mechanism 5 at the top of the transport mechanism 4 forks large clods of soil and removes large stones mixed in the soil to prevent blockages in subsequent stages. The pre-treated soil falls from the discharge port of the transport mechanism 4 into the soil crushing and screening device 6 below, further crushing small clods to a uniform particle size. The finely screened soil is then spread back onto the land. At this time, the chemical mixing device 7 discharges a uniformly mixed remediation agent through its outlet, mixing it with the soil as it is spread back onto the land, achieving rapid in-situ remediation and reuse of the contaminated soil. When the soil in the soil crushing and screening device 6 reaches its processing limit, the transport mechanism 4 temporarily stops conveying soil to the soil crushing and screening device 6. The transport mechanism 4 resumes conveying soil only after the soil in the soil crushing and screening device 6 has been processed.

[0060] The adjustment mechanism 2 includes a fixed frame 21, a motor I 22, a lead screw 23, a sliding plate I 24, a connecting frame 25, a hydraulic cylinder I 29, and a mounting frame 210. The fixed frame 21 is installed on one side of the adjustment port 102 of the mounting platform 101. The motor I 22 is installed on the top of the fixed frame 21. The output shaft of the motor I 22 passes through the fixed frame 21 and is fixedly connected to the lead screw 23, which is rotatably installed on the mounting platform 101. The sliding plate I 24 is slidably connected to the fixed frame 21 and threadedly connected to the lead screw 23. The frame 25 is located inside the adjustment port 102 and is fixedly connected to the sliding plate I24. The connecting frame 25 is provided with mounting plates I26 on both sides. One side of the mounting plate I26 is provided with a bearing seat. The mounting frame 210 is provided with a rotating shaft I27 on one side. The mounting frame 210 is movably connected to the bearing seat on one side of the mounting plate I26 through the rotating shaft I27. The other side of the mounting plate I26 is provided with a fixing plate I28. A hydraulic cylinder I29 is hinged to one side of the fixing plate I28. The ejector end of the hydraulic cylinder I29 is hinged to the mounting frame 210.

[0061] As can be seen from the above description: the output shaft of motor I22 drives the lead screw 23 to rotate, which drives the sliding plate I24 to move up and down along the fixed frame 21, and drives the mounting plate I26 in the adjustment port 102 to rise and fall synchronously, thereby realizing the adjustment of the soil turning mechanism 3's soil penetration depth;

[0062] When the soil turning angle needs to be adjusted, hydraulic cylinder I29 is activated. The top end of hydraulic cylinder I29 pushes or pulls the mounting frame 210. Since the mounting frame 210 is movably connected to the bearing seat of mounting plate I26 through rotating shaft I27, the mounting frame 210 will rotate around rotating shaft I27 under the force of hydraulic cylinder I29, thereby precisely adjusting the working angle of soil turning mechanism 3 to adapt to different soil conditions and soil turning needs.

[0063] The soil-turning mechanism 3 includes a rotating plate 32, connecting rod I 33, fixed plate II 34, fixed plate III 35, motor II 36, limiting shaft 37, and slide rail 38. Fixed plate II 34 and fixed plate III 35 are arranged opposite to each other and are both mounted on a mounting frame 210. Two sets of rotating plates 32 are fixedly connected by several sets of connecting rod I 33. Each set of connecting rod I 33 has a shovel 31 on one side, which is fixedly connected to the rotating plate 32. A bevel gear is provided on the rotating plate 32 on the same side as fixed plate II 34, passing through fixed plate II 34. Motor II 36 is mounted on the mounting frame 210, and the bevel gear on the output shaft of motor II 36 is connected to fixed plate II 34. The rotating plate 32 on the same side of the fixed plate 34 is meshed with a bevel gear. The output shaft bevel gear of the motor II 36 is provided with a protective shell at the meshing point with the rotating plate 32 on the same side of the fixed plate II 34.

The discharge end of the slide 38 passes through the rotating groove of the rotating plate 32 on the same side of the fixed plate III 35 and the installation port on the fixed plate III 35 and is located at the top of the feed port of the conveying mechanism 4. The upper surface of the slide 38 is sloping and the slide 38 is provided with partitions on both sides.

[0064] As described above, after the motor II 36 starts, its output shaft bevel gear meshes with the bevel gear of the rotating plate 32, driving the two sets of rotating plates 32 to rotate stably around the limiting shaft 37. The limiting shaft 37 fits with the rotating groove of the rotating plate 32, limiting the rotation trajectory. The rotation of the rotating plate 32 drives the shovel bucket 31 to rotate synchronously. The shovel bucket 31 delves deeper into the soil as it rotates, shoveling up the contaminated soil and conveying it upwards. The shoveled soil falls onto the slide 38 between the two sets of rotating plates 32. Because the upper surface of the slide 38 is sloping, the soil slides down the slope. The baffles on both sides prevent the soil from spilling. The soil falls into the feed port of the transport mechanism 4 through the discharge end of the slide 38.

[0065] The transport mechanism 4 includes a collection bin 41, a transport bin 42, an auger blade 43, and a motor III 44. The collection bin 41 is fixedly connected to the mounting frame 210.

[0066] As described above, the top inlet of the collection bin 41 receives the soil conveyed by the slide 38. The soil falls from the collection bin 41 into the bottom connected conveying bin 42. The motor III 44 starts and drives the auger blades 43 in the conveying bin 42 to rotate. The auger blades 43 push the soil upward along the conveying bin 42 and push the soil to the top of the conveying bin 42. The soil enters the soil crushing and screening device 6 from the discharge port on the bottom side.

[0067] The soil clod crushing and stone clearing mechanism 5 includes a guide hood 51, an impact head 54, a fixed seat IV 57, a fixed seat V 59, a motor IX 510, a rotating shaft V 511, a connecting rod II 512, a lifting seat 513, a motor X 514, a rotating rod II 515, and a connecting rod III 516. The collection bin 41 is equipped with a guide hood 51, and a fixed seat III 53 is located at the bottom of the guide hood 51. Several sets of fixed seats IV 57 are installed on the fixed seat III 53. Fixed seats V 59 are installed on both sides of the fixed seat IV 57. A lifting seat 513 is slidably installed on the fixed seat V 59. The fixed seat IV 57 is hollow, and the rotating shaft V 511 is rotatably installed inside the fixed seat IV 57.

The turntables 58 are hinged to the connecting rod II 512, and the connecting rod II 512 is hinged to the lifting seat 513. Next, the motor IX 510 is installed at the bottom of the fixed base IV 57. The output shaft bevel gear of the motor IX 510 meshes with the middle bevel gear of the rotating shaft V 511. The lifting base 513 is equipped with several sets of protective shells. The middle of the protective shell is provided with a fixed plate V 517. The motor X 514 is installed on one side of the fixed plate V 517.

The connecting rod III 516 is hinged to the impact head 54. The impact head 54 passes through the fixed plate V 517, the lifting base 513, and the fixed base V 59. One end of the impact head 54 is located inside the protective shell. A buffer damping block 518 is provided on the part of the impact head 54 located at the bottom of the fixed plate V 517. Springs II 519 are provided on both sides of the buffer damping block 518. The springs II 519 are sleeved on the impact head 54.

[0068] The bottom of the fixed base Ⅲ53 is provided with two sets of transport rollers 52. The two sets of transport rollers 52 are located on both sides of the fixed base Ⅲ53 and the middle of the two sets of transport rollers 52 is provided with a stone transport bin 55. A conveyor belt is installed in the stone transport bin 55. A collection box 56 is provided at the bottom of one end of the stone transport bin 55.

[0069] The gap between the transport rollers 52 is smaller than the radius of the auger blades 43 and the impact head 54 is located at the top of the gap between the transport rollers 52;

[0070] As described above, the soil is divided by the guide shroud 51 and flows to both sides of the collection bin 41 towards the conveyor rollers 52. Smaller soil particles fall into the lower collection bin 41 through the gaps between the conveyor rollers 52, while larger stones and clods of soil are conveyed by the conveyor rollers 52 to the stone transport bin 55, and then transported by the conveyor belt to the collection box 56. When the soil clods are transported to the bottom of the impact head 54, the motor IX 510 drives the rotating shaft V 511 to rotate. The turntable 58 pulls the lifting seat 513 up and down along the fixed seat V 59 through the connecting rod II 512, causing the impact to... The head 54 is inserted into the soil block. At the same time, the motor X 514 in the lifting seat 513 drives the rotating rod II 515 to rotate. Through the connecting rod III 516, the impact head 54 is driven to reciprocate at high frequency. The spring II 519 cooperates to buffer and reset, so that the impact head 54 vibrates at high frequency in the soil block like the head of an electric pick, which accelerates the crushing speed of the soil block. This combination of insertion and high-frequency vibration can quickly crush large soil blocks into small particles. The crushed soil particles fall into the lower collection bin 41 between the conveying rollers 52.

The soil turning and crushing mechanism 63 is activated to fully crush the soil and break up the clumps. After the soil is crushed, the isolation mechanism 64 moves down, and the soil moves to the screening mechanism 65 of the screening zone 6102 under the push of the soil turning and crushing mechanism 63. The screening mechanism 65 further screens the soil. Soil that meets the particle size is discharged from the bottom discharge port, while impurities that do not meet the particle size enter the collection hopper 66 on one side.

[0079] While sliding plate II 6304 and sliding shell 6306 slide along S-shaped slide rail 6103, motor V 6315 drives crushing roller 6313 to rotate. Crushing roller 6313 and rotating roller 6321 rotate synchronously. Motor VI 6317 drives electric push rod 6316 to rotate. The telescopic end of electric push rod 6316 pushes crushing blade 6314 to cut and crush the clumps on the soil surface. Hydraulic cylinder III 6325 on rotating roller 6321 drives flipping plate 6320 to swing up and down through swing rod 6326, turning the soil at the bottom of crushing zone 6101 of processing chamber 61 to the soil surface, so that the soil reacts fully with quicklime, changes the compacted structure of the soil, and makes the soil crushing more uniform.

[0080] When the sliding plate II 6304 and the sliding shell 6306 slide to one end of the S-shaped slide rail 6103 and return, the hydraulic cylinder II 6308 drives the top rack to slide, driving the rotating frame 6309 to rotate, causing the crushing roller 6313 and the rotating roller 6321 to flip, ensuring that the soil turning and crushing mechanism 63 proceeds in the order of first crushing the clumps on the soil surface and then turning the soil at the bottom to the soil surface.

[0081] The isolation mechanism 64 includes an isolation plate 6401, a motor VII 6402, and a rotating shaft III 6403. The isolation plate 6401 is slidably installed inside the processing chamber 61.

The bevel gear on the output shaft of the motor VII 6402 meshes with the bevel gear in the middle of the rotating shaft III 6403.

[0082] As described above, when the soil is crushed in the crushing zone 6101, the isolation plate 6401 is in a closed state, separating the crushing zone 6101 from the screening zone 6102. After crushing, the bevel gear on the output shaft of motor VII 6402 drives the bevel gear in the middle of the rotating shaft III 6403 to rotate, so that the rotating shaft III 6403 rotates synchronously. The two sets of gears on the rotating shaft III 6403 rotate and drive the rack to slide the isolation plate 6401 downward. After the isolation plate 6401 moves down, the crushing zone 6101 and the screening zone 6102 are connected, which facilitates the soil to enter the screening stage.

[0083] A discharge port is provided on one side of the isolation plate 6401. A screening mechanism 65 is installed on top of the discharge port. The screening mechanism 65 includes a screen 6501, a screening frame 6502, a fixed seat I 6503, a spring I 6507, a rotating shaft IV 6508, and a motor VIII 6509.

Hydraulic cylinders IV 6504 are provided at both ends of the screening frame 6502. The output ends of the hydraulic cylinders IV 6504 are rotatably connected to both ends of the screening frame 6502. The hydraulic cylinders IV 6504 are hinged to the fixed seats I 6503 on both sides of the discharge port. Baffles 6505 are provided at both ends of the screening frame 6502. The baffles 6505 are located in the slide rails 6104 of the processing chamber 61. 04 On the outer side, a screen 6501 is slidably installed on the screen frame 6502. Two sets of fixed seats II 6506 are provided at the bottom of the screen 6501. The fixed seats II 6506 are fixedly connected to the screen frame 6502. Several sets of telescopic rods are installed on the fixed seats II 6506. The telescopic ends of the telescopic rods are fixedly connected to the screen 6501. Springs I 6507 are sleeved on the telescopic rods. Two sets of rotating shafts IV 6508 are rotatably installed at the bottom of the screen 6501. An eccentric wheel is provided on the rotating shafts IV 6508. A synchronous pulley is provided at one end of the rotating shafts IV 6508. The two sets of synchronous pulleys are connected by a synchronous belt drive. The output shaft of the motor VIII 6509 is fixedly connected to one set of rotating shafts IV 6508. The motor VIII 6509 is installed at the bottom of the screen frame 6502.

[0084] As described above, after the soil is crushed in the crushing zone 6101, the isolation plate 6401 moves downward, the soil-turning and crushing mechanism 63 moves along the S-shaped slide rail 6103, and the turning plate 6320 changes the turning angle to slowly push the soil from the crushing zone 6101 into the top of the screen 6501 in the screening section 6102. The motor VIII 6509 drives a set of rotating shafts IV 6508 to rotate, which in turn drives another set of rotating shafts IV 6508 to rotate synchronously via a synchronous belt drive. The eccentric wheel on the shaft rotates accordingly, causing the screen 6501 to vibrate at high frequency. During vibration, the telescopic rod on the fixed seat II 6506, together with the spring I 6507, buffers the screen and prevents it from shaking excessively. Soil that meets the particle size requirements is discharged through the discharge port after screening, while soil that does not meet the particle size requirements is discharged into the collection bin 66 under the vibration of the screen 6501. After screening, the hydraulic cylinders IV 6504 on both sides quickly push the screen frame 6502 to slide along the slide rail 6104 of the processing bin 61, throwing the soil remaining on the screen into the collection bin 66. The baffles 6505 at both ends prevent soil from leaking out from the gaps in the slide rail.
