Description

Technical Field

[0001] This utility model relates to the technical field of soil remediation, specifically to a soil heavy metal pollution remediation device. Background Technology

[0002] Soil heavy metal pollution has become a pressing global ecological and environmental problem, primarily stemming from industrial wastewater discharge, overuse of pesticides and fertilizers, and atmospheric deposition, leading to excessive levels of heavy metals such as cadmium, lead, chromium, and arsenic in the soil. Heavy metals are persistent, bioaccumulative, and toxic, not only damaging soil structure and reducing soil fertility but also entering the food chain through crop absorption, posing a serious threat to human health. Therefore, developing efficient and practical soil heavy metal pollution remediation equipment is crucial for ensuring soil safety and the ecological environment. Traditional soil remediation equipment includes a remediation solution spraying structure and a soil turning mechanism. The turning mechanism loosens the topsoil, and then the spraying structure sprays the remediation solution onto the soil surface. However, due to the limited permeability of the soil itself, the remediation solution cannot effectively penetrate into the deeper soil layers, resulting in insufficient treatment of heavy metals in the deeper soil layers. Utility Model Content

[0003] This invention proposes a soil heavy metal pollution remediation device, which uses soil turning teeth to turn the soil and expose the surface pollution, while a conical tube is periodically inserted into the deep soil through reciprocating oscillation, so that the remediation liquid is not only sprayed on the loosened soil surface, but can also penetrate into the soil interior through the conical tube.

[0004] Therefore, the technical solution adopted is as follows:

[0005] A soil heavy metal pollution remediation device includes a mobile support frame. The mobile support frame is connected to a remediation mechanism via a lifting device. The remediation mechanism includes a mounting frame. A rotating roller is rotatably connected to the mounting frame. The rotating roller is driven to rotate by a power source. Several soil turning teeth are evenly fixed above the roller. A swing shaft is also rotatably connected to the mounting frame. The swing shaft is parallel to the rotating roller. Its outer wall has a swing rod perpendicular to its axis. One end of the swing rod is fixed to the swing shaft, and the other end is fixed to a conical tube. The conical tube is connected to a storage tank via a liquid infusion tube. The tip of the conical tube is set downwards, and several through holes are opened on its side wall. The power source synchronously drives the swing shaft to reciprocate.

[0006] A further technical solution is that the power source includes a drive motor, the output shaft of the drive motor is coaxially fixed to one end of the rotating roller, the other end of the rotating roller is fixed to a swing block, a rack is slidably connected to the mounting frame, the swing block is rotatably connected to the mounting frame, a connecting rod is rotatably connected to the swing block at an eccentric position, the other end of the connecting rod is rotatably connected to the rack, and a gear is fixed to the end of the swing shaft, the gear meshing and matching with the rack.

[0007] A further technical solution is that a handrail is fixed on one side of the mobile support, a walking wheel is rotatably connected to the bottom, and a mounting plate is fixed on the top, with the liquid storage tank fixed on the mounting plate.

[0008] A further technical solution is that the lifting device includes a lifting cylinder, the fixed end of which is fixed to the mounting plate, and the telescopic end is fixedly connected to the mounting frame.

[0009] A further technical solution is that the swing rod has multiple swing rods arranged in an array along the swing axis, and the other end of several swing rods that are not fixed to the swing axis is fixed to a connecting pipe. The infusion tube is a flexible tube and is connected to the inlet of the connecting pipe. Several outlets connected to each conical tube are correspondingly opened on the connecting pipe.

[0010] A further technical solution is that the tapered tube is connected to a check valve.

[0011] The working principle and beneficial effects of this application are as follows:

[0012] By incorporating a remediation mechanism, the soil is turned over using turning teeth to expose surface contaminants. At the same time, a conical tube is periodically inserted into the deep soil through reciprocating oscillation. This allows the remediation solution to not only be sprayed onto the loosened soil surface but also penetrate deep into the soil through the conical tube, achieving synergistic remediation of surface loosening and deep penetration. This overcomes the limitation of traditional equipment that can only remediate surface soil and results in a higher heavy metal removal rate. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1-4 As shown, a soil heavy metal pollution remediation device includes a mobile support 1. The mobile support 1 is connected to a remediation mechanism 6 via a lifting device. The remediation mechanism 6 includes a mounting frame 61, on which a rotating roller 63 is rotatably connected. The rotating roller 63 is driven to rotate by a power source, and several soil-turning teeth 64 are evenly fixed above it. A swing shaft 614 is also rotatably connected to the mounting frame 61. The swing shaft 614 is arranged parallel to the rotating roller 63, and its outer wall has a swing rod 66 perpendicular to its axis. One end of the swing rod 66 is fixed to the swing shaft 614, and the other end is fixed to a conical tube 67. The conical tube 67 is connected to a storage tank 5 via a liquid infusion pipe 613. The tip of the conical tube 67 is set downwards, and several through holes are opened on its side wall. The power source synchronously drives the swing shaft 614 to reciprocate. A handrail 2 is fixed to one side of the mobile support 1, a traveling wheel 3 is rotatably connected to the bottom, and a mounting plate 4 is fixed to the top. The storage tank 5 is fixed to the mounting plate 4.

[0021] In this embodiment, the operator holds the handle 2 and pushes the mobile support 1, using the rotating wheels 3 at the bottom to move the equipment to the contaminated soil area. The lifting device is activated, driving the mounting frame 61 to descend as a whole until the turning teeth 64 on the rotating roller 63 contact the soil surface. The turning depth is controlled by adjusting the lifting amplitude to adapt to different contamination layer thicknesses. The rotating roller 63 is controlled by the power source to rotate, driving the turning teeth 64 on its outer wall to rotate synchronously, turning and loosening the soil, exposing the surface and shallow heavy metals of the soil, facilitating the contact of the subsequent remediation fluid. Simultaneously, the water pump in the storage tank 5 is started, delivering the remediation fluid through the infusion pipe 613 to the connecting pipe 68, and then diverting it to multiple conical pipes 67. The remediation fluid flows out through the through holes on the outer wall of the conical pipe 67 and is sprayed onto the turned soil surface.

[0022] During the rotation of the rotating roller 63, the swing rod 66 simultaneously performs a reciprocating swing motion, causing the conical tube 67 to periodically insert into the soil. This allows the remediation liquid to not only be sprayed onto the loosened soil surface but also penetrate deep into the soil through the conical tube 67, achieving synergistic remediation of "surface loosening and deep penetration." It should be noted that the lowest height of the conical tube 67 when it swings with the swing rod 66 is lower than the lowest height of the turning teeth 64.

[0023] like Figures 2-3 As shown, it includes a lifting cylinder 65, the fixed end of which is fixed to the mounting plate 4, and the telescopic end is fixedly connected to the mounting frame 61. The lifting cylinder 65 is used to adjust the lifting range of the mounting frame 61, thereby controlling the soil turning depth and adapting to different contamination layer thicknesses.

[0024] like Figures 2-4 As shown, one embodiment of the power source includes a drive motor 62, the output shaft of which is coaxially fixed to one end of a rotating roller 63, and a swing block 69 fixed to the other end of the rotating roller 63. A rack 611 is slidably connected to the mounting bracket 61, and the swing block 69 is rotatably connected to the mounting bracket 61. A connecting rod 610 is rotatably connected to the swing block 69 at an eccentric position, and the other end of the connecting rod 610 is rotatably connected to the rack 611. A gear 612 is fixed to the end of the swing shaft 614, and the gear 612 meshes with the rack 611.

[0025] In this embodiment, the drive motor 62 is started, and the output end of the drive motor 62 drives the rotating roller 63 to rotate. When the rotating roller 63 rotates, the swing block 69 fixedly connected to it rotates synchronously. The swing block 69 drives the rack 611 to slide back and forth along the side wall of the mounting frame 61 through the connecting rod 610. The rack 611 meshes with the gear 612. The sliding of the rack 611 drives the gear 612 to rotate, which in turn drives the swing shaft 614 fixedly connected to the gear 612 to rotate. Finally, the swing rod 66 on the swing shaft performs a reciprocating swing action, which drives the conical tube 67 to periodically insert into the soil. This allows the remediation liquid to not only be sprayed on the loosened soil surface, but also penetrate deep into the soil through the conical tube 67, achieving synergistic remediation of surface loosening and deep penetration.

[0026] It should be noted that the through hole of the tapered tube 67 has a built-in check valve to prevent soil from entering in the reverse direction. When the repair fluid is delivered to the tapered tube 67 through the connecting pipe 68, the liquid pressure pushes open the check valve, and the repair fluid sprays out from the through hole. When the delivery stops, the check valve automatically closes to prevent external soil from entering the through hole. Because the soil that has been turned over is soft, it will not easily block the through hole of the tapered tube 67 under the action of the check valve.

[0027] like Figure 4As shown, multiple swing rods 66 are arranged in an array along the axis of the swing shaft 614. The other end of each swing rod 66, which is not fixed to the swing shaft 614, is fixed to a connecting pipe 68. The infusion pipe 613 is a flexible tube and is connected to the inlet of the connecting pipe 68. The connecting pipe 68 has several outlets corresponding to each tapered tube 67. The flexible tube 613 is designed to accommodate the reciprocating swing of the swing rods 66, preventing damage to the pipe due to rigid stress.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
