Description

Technical Field

[0001] This invention relates to the field of soil screening technology, and in particular to a screening device for soil pollution remediation. Background Technology

[0002] With rapid industrialization and urbanization, large amounts of heavy metals, chemicals, and other harmful substances are being released into the environment, leading to increasingly serious soil pollution. These pollutants not only affect soil quality but also endanger human health through the food chain. Soil pollution remediation screening devices, as an effective tool, are widely used in the screening and grading of contaminated soil. By screening contaminated soil, its particle size distribution, pollutant distribution, and migration patterns can be understood, providing a scientific basis for subsequent pollution remediation and treatment.

[0003] In traditional soil screening processes, when large soil particles pass through the screen, the pollutants trapped inside are difficult to release effectively, making it difficult to weaken the binding force between the pollutants and the soil particles. At the same time, due to the uneven size of soil particles, small particles easily pass through the screen while large particles are retained, resulting in incomplete screening and seriously affecting screening efficiency and pollution control effects. Traditional screening methods also easily lead to excessive wear of soil particles during the screening process, damaging the soil structure and making the screened soil particles easily damaged and unable to meet the requirements for subsequent use. Therefore, it is necessary to propose a screening device for soil pollution control. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as uneven soil particle size leading to incomplete screening where small particles easily pass through the screen while large particles are retained, severely affecting screening efficiency and pollution control effectiveness. Traditional screening methods also tend to cause excessive wear of soil particles during screening, damaging the soil structure and making the screened soil particles easily damaged. Therefore, this invention proposes a screening device for soil pollution control.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screening device for soil pollution remediation includes a base plate and a vibrating plate. A top plate is fixedly connected to the upper part of the base plate. A second rotating shaft is movably connected to the top plate near the base plate. A soil grinding output assembly is jointly arranged on the top plate and the second rotating shaft. The soil grinding output assembly includes a grinding plate movably connected to the second rotating shaft, an annular tank fixedly connected to the lower part of the top plate, a gear shaft movably connected to the inner side of the annular tank, an annular gear rotatably connected to the inner side of the annular tank, and a push rod movably connected to the annular gear. The rotation of the second rotating shaft drives the grinding plate to move back and forth in the vertical direction. The movement of the grinding plate grinds the soil. The rotation of the gear shaft drives the annular gear to rotate inside the annular tank. The movement of the rotating rod causes the push rod to rotate, which in turn moves the ground soil. An adjustable amplitude screening assembly is provided on both the top plate and the vibrating plate. This assembly includes a turntable on the top plate, a pull rod movably connected to the turntable, a moving block movably connected to the vibrating plate, and a movable ball movably connected to the moving block. The rotation of the turntable causes the pull rod to rotate, and the movement of the moving block causes the pull rod to move. The movement of the pull rod adjusts the vertical amplitude of the vibrating plate. A screening box is located on the outer side of the vibrating plate, and a storage box is located on the outer side of the bottom plate. Different amplitudes of vibration of the vibrating plate cause the screening box to move, and the vibration of the screening box sieves the soil into the inner side of the storage box.

[0007] The above technical solution further includes:

[0008] The bottom plate is symmetrically and fixedly connected to the top plate on one side. The two sets of support columns are fixedly connected to the top plate at the ends away from the bottom plate. The support columns mainly serve to support the top plate. The top plate is fixedly connected to the side away from the bottom plate. The output shaft of the first servo motor is fixedly connected to the end of the first servo motor. A transmission belt is sleeved on the outside of the first rotation shaft. The end of the transmission belt away from the first rotation shaft is connected to the second rotation shaft. The end of the second rotation shaft away from the bottom plate is rotatably connected to the top plate. The rotation of the transmission belt will drive the second rotation shaft to rotate.

[0009] A threaded rod is fixedly connected to the end of the second rotating shaft away from the top plate. The threaded rod is threadedly connected to the grinding plate. An input pipe is fixedly connected to the side of the grinding plate near the top plate. The rotation of the threaded rod will cause the grinding plate to move back and forth in the vertical direction.

[0010] A connecting rod is fixedly connected to the side of the top plate near the bottom plate. The outer side of the connecting rod is fixedly connected to the annular tank, and the inner side of the annular tank is slidably connected to the grinding plate. The function of the connecting rod is to connect the top plate and the annular tank, and the connecting rod can keep the annular tank stable.

[0011] The inner side of the annular tank is provided with a placement groove, and a second servo motor is fixedly connected to the bottom of the inner side of the placement groove. The output shaft end of the second servo motor is fixedly connected to the gear shaft. The bottom of the inner side of the annular tank is rotatably connected to the annular gear. The annular gear and the gear shaft mesh with each other. The rotation of the gear shaft will drive the annular gear to rotate at the bottom of the inner side of the annular tank.

[0012] The inner side of the ring gear has a sliding groove, and a spring is fixedly connected to the bottom of the inner side of the sliding groove. The end of the spring away from the sliding groove is fixedly connected to the push rod, and the end of the push rod away from the sliding groove is movably connected to the threaded rod. The bottom of the ring tank has an output hole, and the rotation of the push rod can push the ground soil to the inside of the output hole.

[0013] The end of the first rotating shaft away from the first servo motor is fixedly connected to the turntable, the end of the turntable away from the first rotating shaft is movably connected to the pull rod, and the end of the pull rod away from the turntable is fixedly connected to the movable ball. The rotation of the pull rod will cause the movable ball to move outside the fixed block.

[0014] The support column and the vibrating plate are slidably connected. A third servo motor is fixedly connected to the side of the vibrating plate away from the base plate. A lead screw is fixedly connected to the output shaft end of the third servo motor. The lead screw and the moving block are threadedly connected. A fixed block is fixedly connected to the side of the moving block away from the base plate. The end of the fixed block away from the moving block is movably connected to a movable ball. The movable ball is embedded in the outside of the fixed block. As the pulling rod rotates, the pulling rod can drive the fixed block, thereby causing the vibrating plate to vibrate in the vertical direction.

[0015] The vibrating plate is fixedly connected to the screening box on the side away from the bottom plate, and the bottom plate is fixedly connected to the storage box on the side close to the vibrating plate. The vibration of the vibrating plate will drive the screening box to move in the vertical direction.

[0016] The present invention has the following beneficial effects:

[0017] 1. In this invention, by setting up a soil grinding output component, the grinding plate moves back and forth in the vertical direction driven by the second rotating shaft to perform fine grinding on the soil. This step effectively breaks down the large particle structure in the soil, increases the looseness of the soil, weakens the binding force between pollutants and soil particles, and facilitates subsequent screening and pollution control work. At the same time, the grinding process also promotes the homogenization of soil particles and improves screening efficiency.

[0018] 2. In this invention, by setting an adjustable amplitude screening component, the amplitude of the vibrating plate in the vertical direction can be flexibly adjusted through the cooperation of the turntable, pull rod, moving block and movable ball. This adjustable amplitude design can not only accurately control the screening force according to different pollution levels and types of soil to ensure the maximum screening effect, but also adapt to various screening needs, improve screening efficiency and accuracy. At the same time, by adjusting the amplitude, excessive wear of soil particles during the screening process can be effectively avoided, protecting the soil structure. Attached Figure Description

[0028] Example 1

[0029] like Figures 1-7 As shown, the present invention proposes a screening device for soil pollution remediation, comprising a base plate 1 and a vibrating plate 23.

The rotation of the gear shaft 15 will drive the annular gear 16 to rotate inside the annular tank 12, and the rotation of the annular gear 16 will... The rotating push rod 19 causes the ground soil to move. An adjustable amplitude screening assembly is provided on the top plate 3 and the vibrating plate 23.

The movement of the pull rod 22 adjusts the vertical amplitude of the vibrating plate 23. A screening box 29 is provided on the outside of the vibrating plate 23, and a storage box 30 is provided on the outside of the bottom plate 1. The vibration of the vibrating plate 23 at different amplitudes causes the screening box 29 to move. The vibration of the screening box 29 will screen the soil into the inside of the storage box 30.

[0030] Support columns 2 are symmetrically fixedly connected to the side of the base plate 1 near the top plate 3. The ends of the two sets of support columns 2 away from the base plate 1 are fixedly connected to the top plate 3. The support columns 2 mainly serve to support the top plate 3. A first servo motor 4 is fixedly connected to the side of the top plate 3 away from the base plate 1. A first rotating shaft 5 is fixedly connected to the end of the output shaft of the first servo motor 4. A transmission belt 6 is sleeved on the outside of the first rotating shaft 5. The end of the transmission belt 6 away from the first rotating shaft 5 is connected to the second rotating shaft 7. The end of the second rotating shaft 7 away from the base plate 1 is rotatably connected to the top plate 3. The rotation of the transmission belt 6 will drive the second rotating shaft 7 to rotate.

[0031] The second rotating shaft 7 is fixedly connected to a threaded rod 8 at the end away from the top plate 3. The threaded rod 8 and the grinding plate 9 are threadedly connected. The grinding plate 9 is fixedly connected to an input pipe 10 on the side closer to the top plate 3. The rotation of the threaded rod 8 will drive the grinding plate 9 to move back and forth in the vertical direction.

[0032] A connecting rod 11 is fixedly connected to the side of the top plate 3 near the bottom plate 1. The outer side of the connecting rod 11 is fixedly connected to the annular tank 12, and the inner side of the annular tank 12 is slidably connected to the grinding plate 9. The function of the connecting rod 11 is to connect the top plate 3 and the annular tank 12, and the connecting rod 11 can keep the annular tank 12 stable.

[0033] An inner groove 13 is provided on the inner side of the annular tank 12. A second servo motor 14 is fixedly connected to the bottom inner side of the groove 13. The output shaft end of the second servo motor 14 is fixedly connected to the gear shaft 15. The bottom inner side of the annular tank 12 is rotatably connected to the annular gear 16. The annular gear 16 and the gear shaft 15 mesh with each other. The rotation of the gear shaft 15 will drive the annular gear 16 to rotate at the bottom inner side of the annular tank 12.

[0034] The inner side of the ring gear 16 is provided with a sliding groove 17. A spring 18 is fixedly connected to the bottom of the inner side of the sliding groove 17. The end of the spring 18 away from the sliding groove 17 is fixedly connected to the push rod 19. The end of the push rod 19 away from the sliding groove 17 is movably connected to the threaded rod 8. The bottom of the ring tank 12 is provided with an output hole 20. The rotation of the push rod 19 can push the ground soil to the inside of the output hole 20.

[0035] In this embodiment, the supporting column 2 connects the bottom plate 1 and the top plate 3, and mainly supports the top plate 3. When the first servo motor 4 starts, the rotation of the output shaft end of the first servo motor 4 will drive the first rotating shaft 5 to rotate. The rotation of the first rotating shaft 5 will drive the transmission belt 6 to rotate. The rotation of the transmission belt 6 will drive the second rotating shaft 7 to rotate. The second rotating shaft 7 and the top plate 3 are rotatably connected. When the second rotating shaft 7 rotates, it will drive the threaded rod 8 to rotate. The rotation of the threaded rod 8 will drive the grinding plate 9 to move back and forth in the vertical direction. Before use, the soil needs to enter the inner side of the annular tank 12 from the inner side of the input pipe 10. As the grinding plate 9 moves, it will perform preliminary grinding on the soil inside the annular tank 12. The connecting rod 11 connects the top plate 3 and the top plate 3. The annular tank 12 and the connecting rod 11 keep the annular tank 12 stable. The vertical movement of the grinding plate 9 will squeeze the push rod 19. The push rod 19 will move downward along the inner side of the sliding groove 17 due to the squeezing of the grinding plate 9. When the push rod 19 is no longer squeezed by the grinding plate 9, the push rod 19 will rebound to the initial position due to the action of the spring 18. The function of the second servo motor 14 is to connect the placement groove 13 and the gear shaft 15. When the second servo motor 14 is started, the output shaft end of the second servo motor 14 will drive the gear shaft 15 to rotate. Because the gear shaft 15 and the ring gear 16 are meshed, the rotation of the gear shaft 15 will drive the ring gear 16 to rotate at the bottom of the inner side of the annular tank 12. The rotation of the ring gear 16 will drive the push rod 19 to rotate. The rotation of the push rod 19 can push the ground soil to the inner side of the output hole 20.

[0036] Example 2

[0037] like Figures 1-7 As shown, based on Embodiment 1, the end of the first rotating shaft 5 away from the first servo motor 4 is fixedly connected to the turntable 21, the end of the turntable 21 away from the first rotating shaft 5 is movably connected to the pull rod 22, and the end of the pull rod 22 away from the turntable 21 is fixedly connected to the movable ball 28. The rotation of the pull rod 22 will drive the movable ball 28 to move outside the fixed block 27.

[0038] The support column 2 and the vibrating plate 23 are slidably connected. A third servo motor 24 is fixedly connected to the side of the vibrating plate 23 away from the base plate 1. A lead screw 25 is fixedly connected to the end of the output shaft of the third servo motor 24. The lead screw 25 and the moving block 26 are threadedly connected. A fixed block 27 is fixedly connected to the side of the moving block 26 away from the base plate 1. The end of the fixed block 27 away from the moving block 26 is movably connected to the movable ball 28. The movable ball 28 is embedded in the outside of the fixed block 27. As the pulling rod 22 rotates, the pulling rod 22 can drive the fixed block 27, thereby causing the vibrating plate 23 to vibrate in the vertical direction.

[0039] The vibrating plate 23 is fixedly connected to the screening box 29 on the side away from the bottom plate 1, and the bottom plate 1 is fixedly connected to the storage box 30 on the side close to the vibrating plate 23. The vibration of the vibrating plate 23 will drive the screening box 29 to move in the vertical direction.

[0040] In this embodiment, the rotation of the first rotating shaft 5 causes the turntable 21 to rotate, which in turn causes the pull rod 22 to rotate. The rotation of the pull rod 22 causes the movable ball 28 to move outside the fixed block 27. The movable ball 28 is embedded in the outside of the fixed block 27. As the pull rod 22 rotates, it drives the fixed block 27, thereby causing the vibrating plate 23 to vibrate vertically. The support column 2 mainly serves to limit the movement of the vibrating plate 23. The vibration of the vibrating plate 23 causes the screening box 29 to move vertically. The system can screen the ground soil, and the screened soil will fall into the inner side of the storage box 30. When it is necessary to adjust the vibration amplitude of the vibrating plate 23, the third servo motor 24 is started. The output shaft of the third servo motor 24 rotates, which drives the lead screw 25 to rotate. Because the lead screw 25 and the moving block 26 are threadedly connected, the rotation of the lead screw 25 can drive the moving block 26 to move back and forth in the horizontal direction. By adjusting the different positions of the moving block 26, different amplitudes of the vibrating plate 23 can be achieved. The larger the amplitude, the greater the throwing force and movement intensity of the soil particles on the screening box 29, thereby improving the screening efficiency.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
