Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, specifically to an excavation-type deep remediation device for contaminated soil. Background Technology

[0002] Soil remediation involves adding solidifying or stabilizing agents to contaminated soil to fully mix it with the contaminating medium or pollutants. This can be achieved through physical methods to solidify the contaminated soil into a structurally intact, low-permeability fixed body, or through chemical reactions to convert pollutants into a chemically inert form, thereby reducing the migration and diffusion of pollutants in the environment.

[0003] In the reagent operation, solidifying agents and active stabilizers are sprayed on the soil surface. However, the chemical agents are only sprayed on the soil surface, which limits the treatment effect on the deep soil and makes it difficult to remediate the soil. The soil and chemical reagents are not mixed evenly, which leads to the waste of chemical reagents. After the soil is dug into trenches and crushed and mixed by the mixing equipment, it takes time to backfill the soil, which increases the soil remediation process, making the soil remediation time longer and the efficiency low.

[0004] Based on this, the present invention designs a deep remediation device for excavated contaminated soil to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an excavation-type deep remediation device for contaminated soil, in order to solve the problems mentioned in the background art, such as limited deep soil remediation effect and cumbersome backfilling.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A deep remediation device for contaminated soil using an excavation method includes a drive vehicle body. A mounting plate is located at the front end of the drive vehicle body, and a mounting frame is mounted on the mounting plate. Two sets of driven gears are rotatably mounted on the mounting frame. A material intake pipe is threadedly connected to one set of driven gears farther from the drive vehicle body, and a backfill pipe is threadedly connected to the other set of driven gears closer to the drive vehicle body. A processing box is fixedly mounted at the upper ends of the material intake pipe and the backfill pipe. A partition is provided inside the processing box. A material intake shaft is located inside the material intake pipe, and a backfill shaft is located inside the backfill pipe. A screw feeder is fixedly mounted on both the material intake shaft and the backfill shaft. The upper ends of the material intake shaft and the backfill shaft extend through the processing box and above it. A transition component is provided between the material intake shaft and the backfill shaft. This transition component can fully mix the soil with a solidifying agent and transfer the soil to the other side of the partition.

[0008] Preferably, the transition component includes a toothed chain and a drive component. The toothed chain has two sets. The drive component is rotatably mounted on the upper surface of the processing box. The toothed chain is sleeved on the outside of the drive component. The upper surface of the processing box has a movable groove corresponding to the position of the toothed chain. A movable shaft is provided in the movable groove. A movable gear is fixedly installed at the upper end of the movable shaft. The movable gear meshes with the toothed chain. The lower end of the movable shaft extends into the processing box and is fixedly installed with multiple stirring rods. A transmission component is provided on the drive component, which can make the drive component periodically rotate forward and backward.

[0009] Preferably, the transmission assembly includes an intermediate gear and a transmission rod. The intermediate gear is fixedly mounted on the drive component, and the transmission rod is rotatably connected to the processing box. Positioning wheels are fixedly mounted on both the transmission rod and the material picking shaft. Positioning belts are sleeved on the positioning wheels. A drive gear is fixedly mounted on the lower end of the transmission rod, and a driven gear is fixedly mounted on the backfill shaft. The drive gear meshes with the driven gear.

[0010] Preferably, a first movable rod is provided on the side of the intermediate gear near the backfill shaft, and a second movable rod is provided on the side of the intermediate gear near the material taking shaft. A first transmission wheel is fixedly installed on both the first movable rod and the backfill shaft. A first transmission belt is sleeved on the first transmission wheel. A first half-width gear is fixedly installed on the lower end of the first movable rod. A second transmission wheel is fixedly installed on both the second movable rod and the material taking shaft. A second transmission belt is sleeved on the second transmission wheel. A second half-width gear is fixedly installed on the lower end of the second movable rod. The second half-width gear and the first half-width gear mesh with the intermediate gear in sequence.

[0011] Preferably, a movable plate is slidably connected to the partition, the upper end of the movable plate extends above the processing box, and teeth are provided on the movable plate. A micro motor is fixedly installed on the upper surface of the processing box, and a limit gear is fixedly installed at the output end of the micro motor. The limit gear meshes with the teeth on the movable plate. A protruding stop is fixedly installed inside the processing box and above the material receiving pipe. A limit block is fixedly installed on the side of the protruding stop near the partition. A recessed stop is fixedly installed inside the processing box corresponding to the position of the backfill pipe.

[0012] Preferably, a drive motor is fixedly mounted on the lower surface of the mounting plate, a drive gear is fixedly mounted on the output end of the drive motor, the drive gear meshes with the driven gear, and a cleaning component is fixedly mounted on the backfill shaft.

[0013] Preferably, a movable component is fixedly installed at the lowest end of the material intake pipe and the backfill pipe, a soil cutting component is fixedly installed on the lower surface of the movable component, and multiple sets of crushing blades are arranged above the movable component.

[0014] Preferably, a driving device is provided on the upper surface of the processing box, the output end of the driving device is fixedly connected to the material picking shaft, and a curing agent inlet is provided on one side of the processing box.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In this invention, the material intake pipe and the backfill pipe work together, and the material intake shaft and the backfill shaft rotate continuously. As the material intake pipe and the backfill pipe move downwards, the rotation of the material intake shaft drives the bottom movable part to rotate. The rotation of the movable part drives the soil cutting part at the bottom of the material intake pipe to break the adhesion of the surface soil, ensuring that the material intake pipe can extend into the deep soil layer. During the extension of the material intake pipe, the soil gradually moves upwards with the spiral feeding part on the material intake shaft and enters the treatment box. In the treatment box, it is uniformly mixed with the curing agent to achieve the repair of deep soil and surface soil. Moreover, during the repair process, the curing agent can be uniformly mixed with deep soil and surface soil, avoiding waste of curing agent. After soil remediation is completed, the micro motor drives the limit gear to rotate. The rotation of the limit gear causes the movable plate to move upward, so that the remediated soil above the material intake pipe can enter the backfill pipe under the action of the movable shaft and the mixing rod. When the material intake pipe moves down to excavate the soil, the backfill pipe backfills the remediated soil in the pit excavated by the previous material intake pipe. The soil can be automatically backfilled while excavating the remediated soil, which simplifies the soil remediation and backfilling process, reduces labor requirements, and improves the efficiency of soil remediation and backfilling.

[0032] Meanwhile, a first movable rod 21 is provided on the side of the intermediate gear 24 near the backfill shaft 12, and a second movable rod 42 is provided on the side of the intermediate gear 24 near the material taking shaft 11.

The second half-width gear 29 and the first half-width gear 22 mesh with the intermediate gear 24 in sequence.

[0033] A movable plate 30 is slidably connected to the partition 35. The upper end of the movable plate 30 extends above the processing box 1. The movable plate 30 is provided with teeth. A micro motor 32 is fixedly installed on the upper surface of the processing box 1. A limit gear 31 is fixedly installed at the output end of the micro motor 32. The limit gear 31 meshes with the teeth on the movable plate 30. A protruding stop block 37 is fixedly installed inside the processing box 5 and above the corresponding material receiving pipe 3. A limit block 40 is fixedly installed on the side of the protruding stop block 37 near the partition 35.

[0034] In addition, a drive motor 43 is fixedly installed on the lower surface of the mounting plate 2, and a drive gear 6 is fixedly installed on the output end of the drive motor 43. The drive gear 6 meshes with the driven gear 41, and a cleaning component 36 is fixedly installed on the backfill shaft 12.

[0035] The bottom of the material intake pipe 3 and the backfill pipe 4 are fixedly installed with a movable part 15, and a soil cutting part 27 is fixedly installed on the lower surface of the movable part 15. Multiple sets of crushing blades 28 are arranged above the movable part 15.

[0036] The upper surface of the processing box 1 is provided with a driving device, the output end of which is fixedly connected to the material feeding shaft 11, and a curing agent inlet is provided on one side of the processing box 1.

[0037] In use, the drive motor 43 drives the drive gear 6 to rotate, which in turn drives the driven gear 41 meshing with it to rotate. The driven gear 41 drives the feed pipe 3 and backfill pipe 4, which are threadedly connected to it, to move downwards, so that the lower ends of the feed pipe 3 and backfill pipe 4 are attached to the soil surface. At the same time, the drive device drives the feed shaft 11 to rotate. The rotation of the feed shaft 11 drives the transmission rod 20 to rotate through the positioning wheel 18 and positioning belt 19. The rotation of the transmission rod 20 drives the bottom drive gear 14 to rotate, which in turn drives the driven gear 13 meshing with it to rotate. The rotation of the driven gear 13 drives the backfill shaft 12 to rotate, thus collecting the feed. Shaft 11 and backfill shaft 12 rotate continuously. As the material intake pipe 3 and backfill pipe 4 move downward, the rotation of the material intake shaft 11 drives the bottom movable part 15 to rotate. The rotation of the movable part 15 drives the soil cutting part 27 at the bottom of the material intake pipe 3 to break the adhesion of the surface soil, ensuring that the material intake pipe 3 can extend into the deep soil layer. During the extension of the material intake pipe 3, the soil gradually moves upward with the spiral feeding part 39 on the material intake shaft 11 and enters the treatment box 5. In the treatment box 5, it is evenly mixed with the curing agent to achieve the repair of deep soil and surface soil. During the repair process, the curing agent can be evenly mixed with deep soil and surface soil to avoid waste of curing agent. After soil remediation is completed, the micro motor 32 drives the limit gear 31 to rotate. The rotation of the limit gear 31 causes the movable plate 30 to move upward, so that the remediated soil above the material intake pipe 3 can enter the backfill pipe 4 under the action of the movable shaft 33 and the stirring rod 34. When the material intake pipe 3 moves downward to excavate the soil, the backfill pipe 4 is backfilled with the remediated soil in the pit excavated by the previous material intake pipe 3. The soil can be automatically backfilled while the soil is being excavated and remediated, which simplifies the soil remediation and backfilling process, reduces labor requirements, and improves the efficiency of soil remediation and backfilling.

[0038] In this invention, through the cooperation between the material intake pipe 3 and the backfill pipe 4, the material intake shaft 11 and the backfill shaft 12 rotate continuously. As the material intake pipe 3 and the backfill pipe 4 move downward, the rotation of the material intake shaft 11 drives the bottom movable part 15 to rotate. The rotation of the movable part 15 drives the soil cutting part 27 at the bottom of the material intake pipe 3 to break the adhesion of the surface soil, ensuring that the material intake pipe 3 can extend into the deep soil layer. During the extension of the material intake pipe 3, the soil gradually moves upward with the spiral feeding part 39 on the material intake shaft 11 and enters the treatment box 5. In the treatment box 5, it is uniformly mixed with the curing agent to achieve the repair of deep soil and surface soil. During the repair process, the curing agent can be uniformly mixed with deep soil and surface soil, avoiding the waste of curing agent. After soil remediation is completed, the micro motor 32 drives the limit gear 31 to rotate. The rotation of the limit gear 31 causes the movable plate 30 to move upward, so that the remediated soil above the material intake pipe 3 can enter the backfill pipe 4 under the action of the movable shaft 33 and the stirring rod 34. When the material intake pipe 3 moves downward to excavate the soil, the backfill pipe 4 is backfilled with the remediated soil in the pit excavated by the previous material intake pipe 3. The soil can be automatically backfilled while the soil is being excavated and remediated, which simplifies the soil remediation and backfilling process, reduces labor requirements, and improves the efficiency of soil remediation and backfilling.

[0039] In this embodiment, the material taking shaft 11 rotates in the opposite direction to the backfilling shaft 12. The material taking shaft 11 drives the second movable rod 42 to rotate through the second transmission wheel 26 and the second transmission belt 23. The rotation of the second movable rod 42 drives the second half-width gear 29 to rotate. The second half-width gear 29 drives the middle gear 24 to rotate, which in turn causes the toothed chain 8 to rotate and drive the movable gear 9 to rotate. When the smooth surface of the second half-width gear 29 rotates to the position of the middle gear 24, the first half-width gear 22 rotates under the action of the backfilling shaft 12 and meshes with the middle gear 24, causing the middle gear 24 to rotate in the opposite direction, which causes the movable gear 9 to rotate in the opposite direction. The movable shaft 33 continuously rotates and moves to uniformly mix the soil and the solidifying agent. After the mixing is completed, the movable shaft 33 moves to drive the repair soil towards the partition 35, which in turn causes the soil to pass through the through groove at the lower end of the partition 35 and enter the backfilling pipe 4.
