Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, specifically to a soil remediation rinsing device with a layer-turning function. Background Technology

[0002] Soil remediation leaching refers to the process of transferring pollutants from the soil phase to the liquid phase by adding water or a suitable synergist to contaminated soil, and then treating and reusing the liquid medium containing the pollutants. At present, soil leaching devices are widely used due to their advantages such as wide applicability, high treatment efficiency and significant effects.

[0003] The prior art discloses a soil remediation rinsing device with a flipping function, which effectively solves the problem that the existing soil rinsing remediation equipment lacks a flipping function, resulting in insufficient contact between the rinsing liquid and the soil, thus affecting the rinsing remediation effect and the use effect. However, the device still has certain limitations in practical applications: it directly transports soil without pre-crushing soil clods with significant differences in particle size, resulting in larger soil clods entering the rinsing stage without being crushed. Due to the low porosity and dense structure of large soil particles, the penetration rate of the rinsing liquid is significantly slowed down during the rinsing process. This makes it difficult for heavy metals (such as lead and cadmium) and organic pollutants (such as polycyclic aromatic hydrocarbons and petroleum hydrocarbons) inside the soil clods to fully dissolve, desorb, undergo ion exchange, or chemical complexation reactions with the rinsing liquid, resulting in incomplete rinsing. At the same time, the rinsed soil has a certain degree of stickiness, which will adhere to the conveyor belt and easily form an adhesion layer on the surface of the conveyor belt. This can easily increase the energy consumption of the conveyor belt and cause the conveyor belt to deviate due to uneven thickness of the adhesion layer, thus aggravating equipment wear. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a soil remediation rinsing device with a layer-turning function to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil remediation leaching device with a turning function, comprising a main body and a conveyor belt. The main body has a feed inlet on one side of its top, and two sets of spraying components on its top. Two sets of first motors are installed on one side of the feed inlet, and the output end of the first motors is connected to a rotating shaft. The outer surface of the rotating shaft is provided with a crushing roller. The spraying components include two sets of piston cylinders, piston rods, piston plates, reciprocating screws, a liquid extraction pipe, and a liquid delivery pipe.

[0006] A material guiding assembly is located at the bottom of the interior of the main body of the device.

[0007] Furthermore, a second motor assembly is installed on the back of the main body of the equipment, and multiple sets of connecting shafts are installed inside the main body of the equipment. Rollers are fixed on the outer surface of each connecting shaft. The conveyor belt is sleeved on the outer surface of the rollers, and the output end of the second motor assembly is connected to a set of connecting shafts.

[0008] By adopting the above technical solution, the second motor assembly drives the rotating roller to rotate through the connecting shaft, thereby driving the sleeved conveyor belt to circulate and transport soil. Multiple sets of rotating rollers can support the middle of the conveyor belt and prevent the middle of the conveyor belt from sinking.

[0009] Furthermore, skirts are fixed to both sides of the conveyor belt, the height of which is 30-50mm, and the skirts are made of rubber and are integrally vulcanized with the conveyor belt.

[0010] By adopting the above technical solution, the annular skirt structure forms a closed material conveying channel, which can effectively prevent soil from overflowing to both sides during the transmission process.

[0011] Furthermore, the spray assembly also includes a drive gear located at one end of the rotating shaft and a liquid storage tank fixed to one side of the main body of the equipment. Two sets of piston cylinders are located at the top of the main body of the equipment. The reciprocating screw is installed on one side of the piston cylinder. A slider is sleeved on the outer surface of the reciprocating screw, and the slider slides in cooperation with the helical groove on the outer surface of the reciprocating screw. One end of the piston rod is fixed to one side of the slider, and one end of the piston rod extends to the inside of the piston cylinder. The piston plate is fixed to one end of the piston rod. The liquid extraction pipe and the liquid delivery pipe are connected to the piston cylinder. One end of the liquid extraction pipe extends to the inside of the liquid storage tank. One end of the reciprocating screw is fixed with a driven gear, and the drive gear meshes with the driven gear. One-way valves are installed on the outer surfaces of the liquid extraction pipe and the liquid delivery pipe.

[0012] By adopting the above technical solution, the spray assembly transmits crushing power synchronously to the spray assembly through the meshing of the driving gear at one end of the rotating shaft and the driven gear at one end of the reciprocating screw. The bidirectional spiral groove on the surface of the reciprocating screw slides with the slider, so that the slider can achieve left and right reciprocating motion when the screw rotates in one direction, driving the piston plate to make linear reciprocating motion in the piston cylinder. When the piston plate moves to the left, the one-way valve on the suction pipe opens, and the washing liquid is drawn from the storage tank, while the one-way valve on the delivery pipe closes at the same time. When the piston plate moves to the right, the one-way valve on the delivery pipe opens, and the washing liquid is sprayed out through the nozzle at a pressure of 0.3-0.5MPa.

[0013] Furthermore, the sliders, piston rods, and piston plates on the two sets of spray assemblies move in opposite directions.

[0014] By adopting the above technical solution, the two sets of spraying components drive the slider through the reciprocating screw bidirectional spiral groove to make the piston plate move in opposite directions, realizing the alternating operation of "one set of liquid pumping and one set of spraying"; this design eliminates the blind zone of rinsing time and makes the rinsing continuous and stable. The sliders, piston rods and piston plates on the two sets of spraying components move in opposite directions.

[0015] Furthermore, the main body of the equipment is equipped with a turning plow and a dispersing rake. The turning plow has a blade angle of 45° and the dispersing rake has a tooth spacing of 30mm. Both the turning plow and the dispersing rake are provided in two sets.

[0016] By adopting the above technical solution, the turning plow lifts and turns the soil upward through the curved structure, and the dispersing rake then combs the falling soil. This combined structure does not require additional power and relies on the kinetic energy transmitted by the soil to achieve automatic turning and dispersing, which significantly improves the contact efficiency between the flushing liquid and the soil.

[0017] Furthermore, the bottom of the infusion tube is provided with several sets of nozzles.

[0018] By adopting the above technical solution, several sets of nozzles form a continuous rinsing area, so that the surface of the broken soil particles can fully contact the rinsing liquid, which significantly improves the dissolution efficiency of harmful substances such as heavy metals and organic pollutants.

[0019] Furthermore, the material guiding assembly includes a guide plate located on one side of the main body of the equipment, and a slide rod is fixed to the bottom of the guide plate. A movable frame is slidably connected to the outer surface of the slide rod, and a scraper is bolted to the top of the movable frame. A screw is installed at the bottom of the movable frame, and the screw is threadedly connected to the bottom of the main body of the equipment.

[0020] By adopting the above technical solution, the structure not only ensures that the scraper effectively removes the adhering soil, but also compensates for scraper wear through screw adjustment. The bolt connection design makes it easier to quickly replace the scraper. Compared with the traditional fixed scraper, the maintenance efficiency is improved and the service life is extended.

[0021] Furthermore, the bottom end of the screw extends to the bottom of the equipment body and is fixed with a knob, and a maintenance port is provided on the lower outer surface of the equipment body.

[0022] By adopting the above technical solution, the operator can drive the screw to rotate by rotating the knob, and use the threaded transmission to drive the movable frame to move up and down along the slide bar, so as to realize convenient adjustment of the gap between the scraper and the conveyor belt. When the scraper needs to be replaced, the bolts can be directly removed from the maintenance port to replace the scraper.

[0023] Furthermore, a control panel is installed on the upper surface of the main body of the device, and both the first motor and the second motor assembly are electrically connected to the control panel.

[0024] By adopting the above technical solution, staff can control the first motor and the second motor assembly through the control panel, and can also adjust the speed of the first motor and the second motor assembly in real time.

[0025] Furthermore, a guide block is fixed on one side of the main body of the equipment, and the top of the guide block is inclined towards the conveyor belt.

[0026] By adopting the above technical solution, the guide block can guide the soil falling from the feed port to the middle of the conveyor belt, avoiding the accumulation of materials at the edge of the equipment.

[0027] In summary, the present invention has the following main advantages:

[0028] 1. This utility model, by setting up two sets of first motors, a rotating shaft, crushing rollers, and two sets of spraying components, allows soil to be added through the feeding port before leaching. The two motors drive the rotating shaft, which in turn drives the two sets of crushing rollers to rotate in opposite directions. Utilizing the toothed structure and clearance fit on the surface of the crushing rollers, larger soil clods (such as lumps with a diameter exceeding 5cm) are crushed into particles smaller than 2cm, increasing the porosity between soil particles by 30%-40%. This creates favorable conditions for subsequent leaching liquid penetration, ensuring that the leaching liquid can fully contact harmful substances in the soil during leaching, thus improving the leaching effect. Furthermore, the rotation of the rotating shaft causes the driving gear to rotate, which in turn causes the reciprocating screw to rotate. This causes the slider to reciprocate linearly along the reciprocating screw, thereby driving the piston rod to move the piston plate periodically within the piston cylinder. The system employs a piston-like motion. When the piston plate of one spray assembly moves to the left, the extraction pipe draws leachate from the storage tank through a one-way valve. Simultaneously, the piston plate of the other spray assembly moves to the right, and the leachate in the piston cylinder is sprayed out from the nozzle through the delivery pipe, achieving uniform rinsing of the crushed soil. Because the sliders of the two spray assemblies are symmetrically distributed along the reciprocating screw, their movement directions are always opposite, forming a "one-set extraction, one-set spraying" linkage working mode. This eliminates the blind spot in rinsing time and makes the rinsing process continuous and stable. In addition, the crushing mechanism and the spray assembly are driven by the same power source, reducing the equipment cost (no need to install a separate pump body), achieving efficient linkage between crushing and rinsing operations, and significantly improving the contact area and reaction efficiency between the rinsing liquid and harmful substances such as heavy metals and organic pollutants in the soil.

[0029] 2. This utility model, by incorporating a material guiding component, allows soil to be discharged from the main body of the equipment via the inclined surface of the guide plate after rinsing, entering the next solid-liquid separation process. Simultaneously configured scrapers are tightly fitted to the bottom of the conveyor belt, effectively scraping off the sticky soil adhering to the conveyor belt surface. The scraped soil is then guided by the guide plate to the next soil solid-liquid separation process. When the scraper wears down due to long-term use, resulting in a gap of more than 2mm between it and the conveyor belt, the operator can rotate the screw, utilizing the threaded hole in the main body of the equipment, to push the movable frame upwards along the slide rod, allowing the scraper to re-engage with the bottom surface of the conveyor belt. For cases of severe scraper wear, the operator can quickly replace the scraper by removing the bolts, significantly improving the ease of equipment maintenance. This material guiding component, in conjunction with the scraper adjustment mechanism, not only achieves efficient discharge of soil after rinsing but also effectively solves the industry-wide common problem of sticky soil adhering to the conveyor belt through its adjustable and detachable scraping structure, reducing maintenance costs.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of this utility model will be described below based on its overall structure.

[0039] Example 1: A soil washing device with a layer-turning function for soil remediation, such as... Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the device includes a main body 1 and a conveyor belt 12. A second motor assembly 8 (planetary gear reducer motor) is mounted on the back of the main body 1. Multiple connecting shafts 10 are installed inside the main body 1, and rollers 11 are fixed to the outer surface of each connecting shaft 10. The conveyor belt 12 is sleeved on the outer surface of the rollers 11, and the output end of the second motor assembly 8 is connected to a set of connecting shafts 10. Skirts 15 are fixed to both sides of the conveyor belt 12. The height of the skirts 15 is 30-50mm, and they are made of rubber and integrally vulcanized with the conveyor belt 12. The annular skirt structure forms a closed material conveying channel, which can effectively prevent soil from overflowing to both sides during the conveying process. The second motor assembly 8 is connected to the connecting shafts 10. The drive roller 11 rotates, thereby driving the sleeved conveyor belt 12 to circulate and transport soil. Multiple sets of rollers 11 can support the middle of the conveyor belt 12 to prevent it from sinking. A feed inlet 2 is provided on one side of the top of the main body 1. Two sets of spraying assemblies 4 are provided on the top of the main body 1. Two sets of first motors 3 (YE3 series high-efficiency three-phase asynchronous motors) are installed on one side of the feed inlet 2, and the output end of the first motor 3 is connected to a rotating shaft 16. A crushing roller 17 is provided on the outer surface of the rotating shaft 16. The spraying assembly 4 includes two sets of piston cylinders 401, piston rods 407, piston plates 404, reciprocating screws 403, a liquid extraction pipe 405, and a liquid delivery pipe 406. The spraying assembly 4 also... The device includes a drive gear 402 located at one end of a rotating shaft 16 and a liquid storage tank 410 fixed to one side of the main body 1. Two sets of piston cylinders 401 are located on the top of the main body 1. A reciprocating screw 403 is installed on one side of the piston cylinder 401. A slider 409 is sleeved on the outer surface of the reciprocating screw 403. The surface of the reciprocating screw 403 is coated with lubricating oil to prevent jamming and rusting. The slider 409 slides in contact with the spiral groove on the outer surface of the reciprocating screw 403. One end of the piston rod 407 is fixed to one side of the slider 409, and one end of the piston rod 407 extends to the inside of the piston cylinder 401. A piston plate 404 is fixed to one end of the piston rod 407. The suction pipe 405 and the infusion pipe 406 are both connected to the piston cylinder 401. The pumping pipe 405 is connected to the inside of the storage tank 410. One end of the reciprocating screw 403 is fixed with a driven gear 408, and the driving gear 402 meshes with the driven gear 408. Lubricating oil is applied between them. One-way valves are installed on the outer surfaces of the pumping pipe 405 and the infusion pipe 406. The spray assembly 4 transmits the crushing power synchronously to the spray assembly 4 through the meshing of the driving gear 402 at one end of the rotating shaft 16 with the driven gear 408 at one end of the reciprocating screw 403. The bidirectional spiral groove on the surface of the reciprocating screw 403 slides with the slider 409, so that the slider 409 can move back and forth when the screw rotates in one direction, driving the piston plate 404 to move linearly back and forth in the piston cylinder 401.When piston plate 404 moves to the left, the one-way valve on suction pipe 405 opens, drawing eluent from storage tank 410, while the one-way valve on delivery pipe 406 closes. When piston plate 404 moves to the right, the one-way valve on delivery pipe 406 opens, spraying eluent through nozzle at a pressure of 0.3-0.5 MPa.

[0040] See Figure 1 , Figure 2 and Figure 5 In the above embodiment, the sliders 409, piston rods 407, and piston plates 404 on the two sets of spray assemblies 4 move in opposite directions. The two sets of spray assemblies 4 drive the sliders 409 to make the piston plates 404 move in opposite directions through the bidirectional spiral groove of the reciprocating screw 403, so as to realize the alternating operation of "one set of liquid pumping and one set of spraying". This design eliminates the blind spot of rinsing time and makes rinsing continuous and stable. The sliders 409, piston rods 407, and piston plates 404 on the two sets of spray assemblies 4 move in opposite directions.

[0041] See Figure 2 In the above embodiment, the bottom of the infusion pipe 406 is provided with several sets of nozzles, which form a continuous rinsing area, so that the surface of the broken soil particles can be fully contacted with the rinsing liquid, which significantly improves the dissolution efficiency of harmful substances such as heavy metals and organic pollutants.

[0042] See Figure 1 In the above embodiment, a control panel 7 is installed above the outer surface of the main body 1 of the equipment, and the first motor 3 and the second motor assembly 8 are both electrically connected to the control panel 7. The first motor 3 and the second motor assembly 8 are installed on the equipment with shock absorbers and anti-loosening bolts (existing technology, not shown), so that the motors are not easily loosened by vibration after installation. The operator can control the first motor 3 and the second motor assembly 8 through the control panel 7, and can also adjust the speed of the first motor 3 and the second motor assembly 8 in real time.

[0043] See Figure 2 In the above embodiment, a guide block 9 is fixed on one side of the main body 1 of the equipment, and the top of the guide block 9 is inclined towards the conveyor belt 12. The guide block 9 can guide the soil falling from the feeding port to the middle of the conveyor belt 12 to avoid the material from accumulating at the edge of the equipment.

[0044] Example 2: To improve soil dispersion and enhance spraying effectiveness, Example 2 is an improvement upon Example 1. (See attached document for details.) Figure 2 and Figure 6The main body 1 of the equipment is equipped with a turning plow 13 and a dispersing rake 14. The turning plow 13 has a blade angle of 45° and the dispersing rake 14 has a tooth spacing of 30 mm. The distance between the turning plow 13 and the dispersing rake 14 and the conveyor belt 12 is 10 mm (to avoid wear on the conveyor belt 12). There are two sets of turning plow 13 and dispersing rake 14. The turning plow 13 lifts and turns the soil upward through the curved surface structure, and the dispersing rake 14 then rakes the falling soil. This combination structure does not require additional power and relies on the kinetic energy of soil transmission to achieve automatic turning and dispersing, which significantly improves the contact efficiency between the flushing liquid and the soil.

[0045] Example 3: To facilitate the cleaning of the conveyor belt, Example 3 is an improvement on Example 1. Referring to the figure, a material guiding assembly 6 is provided at the lower interior of the main body 1. The material guiding assembly 6 includes a guide plate 601 located on one side of the main body 1, and a sliding rod 602 is fixed to the bottom of the guide plate 601. A movable frame 603 is slidably connected to the outer surface of the sliding rod 602, and a scraper 604 is bolted to the top of the movable frame 603. The scraper 604 is made of polyurethane material, making it more wear-resistant and not damaging the conveyor belt 12. A screw 605 is installed at the bottom of the movable frame 603, and the screw 605 is threadedly connected to the bottom of the main body 1. This structure ensures that the scraper 604... 4. Effectively scrapes away adhering soil, and the wear of the scraper 604 can be compensated by adjusting the screw 605. The bolt connection design makes it easier to quickly replace the scraper 604. Compared with the traditional fixed scraper 604, the maintenance efficiency is improved and the service life is extended. The bottom end of the screw 605 extends to the bottom of the equipment body 1 and is fixed with a knob 606. A maintenance port 5 is opened on the lower outer surface of the equipment body 1. The operator can drive the screw 605 to rotate by rotating the knob 606, and use the threaded transmission to drive the movable frame 603 to move up and down along the slide bar 602, so as to realize the convenient adjustment of the gap between the scraper 604 and the conveyor belt 12. When the scraper 604 needs to be replaced, the bolt can be directly removed from the maintenance port 5 to replace the scraper 604.

[0046] The implementation principle of this utility model is as follows: First, the operator starts the first motor 3 and the second motor assembly 8. After the soil to be processed is added through the feeding port, the two sets of first motors 3 synchronously drive the rotating shaft 16, causing the outer crushing rollers 17 to rotate in opposite directions, thus crushing the soil. The rotation of the second motor assembly 8 causes the rotating roller 11 to drive the conveyor belt 12, thereby continuously transporting the soil. Furthermore, when the rotating shaft 16 rotates, the driving gear 402 drives the driven gear 408 to rotate, thus… This causes the reciprocating screw 403 to rotate, thereby causing the slider 409 to reciprocate linearly along the reciprocating screw 403. This, in turn, drives the piston rod 407 to cause the piston plate 404 to perform periodic piston motion within the piston cylinder 401. When the piston plate 404 of one set of spray components 4 moves to the left, the extraction pipe 405 draws the rinsing liquid from the storage tank 410 through the one-way valve. Simultaneously, the piston plate 404 of the other set of spray components 4 moves to the right, and the rinsing liquid in the piston cylinder 401 is sprayed out from the nozzle through the delivery pipe 406. The crushed soil is then uniformly leached. Because the sliders 409 of the two sets of spray components 4 are symmetrically distributed along the reciprocating screw 403, their movements are always opposite, forming a "one set pumping, one set spraying" linkage working mode. This eliminates the blind spot in leaching time. After leaching, the soil is discharged from the main body 1 of the equipment via the inclined surface of the guide plate 601 and enters the next solid-liquid separation process. The synchronously configured scraper 604 is tightly attached to the bottom of the conveyor belt 12, effectively scraping off the sticky soil adhering to the surface of the conveyor belt 12. The scraped soil... The soil is guided by the guide plate 601 to the next soil solid-liquid separation process. When the scraper 604 wears down due to long-term use and a gap of more than 2mm appears between it and the conveyor belt 12, the operator can rotate the screw 605. The screw 605 is engaged with the threaded hole of the main body 1 of the equipment to push the movable frame 603 upward along the slide bar 602, so that the scraper 604 can re-contact the bottom surface of the conveyor belt 12. In the case of severe wear of the scraper 604, the operator can quickly replace the scraper 604 by removing the bolts.
