[0002] Heavy metal soil refers to the phenomenon where excessive amounts of heavy metals are released into the soil by human activities or natural processes, causing their content to exceed the natural background value and leading to the deterioration of soil environmental quality. Industrial activities: Mining, smelting, electroplating, and chemical enterprises discharge "three wastes" (wastewater, waste gas, and waste residue). Agricultural inputs: The unreasonable use of chemical fertilizers, pesticides (such as pesticides containing arsenic and copper), and livestock and poultry manure (feed additives containing heavy metals). Traffic pollution: Vehicle exhaust emissions (containing lead, zinc, etc.) and long-term accumulation in the soil along roadsides. Urban waste: Household waste, electronic waste dismantling, sewage irrigation, etc.

[0003] In existing technologies, when using negative pressure enhanced heavy metal soil leaching remediation devices, workers need to transport contaminated soil into the leaching device, and then the spray system sprays the leaching liquid evenly onto the soil surface through nozzles. However, when heavy metal soil enters the leaching device, the heavy metal soil may be unevenly distributed within the leaching device, which may lead to uneven contact between heavy metal soil and leaching liquid in different locations, reducing reaction efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that when heavy metal soil enters the leaching device, the heavy metal soil may be unevenly distributed in the leaching device, and to propose a negative pressure enhanced heavy metal soil leaching and remediation device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a negative pressure enhanced heavy metal soil leaching remediation device, comprising two support plates, each with an opening extending through its outer wall. Springs are fixedly installed on both sides of each opening, and a movable plate is fixedly installed between the two springs. A limit rod is fixedly installed on the inner wall of each opening, penetrating the movable plate and slidably connected to it. A connecting plate is fixedly installed on the outer wall of one of the movable plates. An L-shaped plate is fixedly installed on the outer wall of one of the support plates, and a first motor is fixedly installed on the outer wall of the L-shaped plate. The output end of the first motor penetrates the L-shaped plate and is fixedly fitted with a cam. A tank is fixedly installed between the two movable plates.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figures 1-4 As shown, this utility model provides a negative pressure enhanced heavy metal soil leaching remediation device, including a support plate 1, of which there are two. Each of the two support plates 1 has an opening 2 through its outer wall. Springs 3 are fixedly installed on both sides inside the opening 2. A movable plate 4 is fixedly installed between the two springs 3. A limit rod 5 is fixedly installed on the inner wall of the opening 2. The limit rod 5 passes through the movable plate 4 and is slidably connected to the movable plate 4. A connecting plate 6 is fixedly installed on the outer wall of one of the two movable plates 4. An L-shaped plate 7 is fixedly installed on the outer wall of one of the two support plates 1. A first motor 8 is fixedly installed on the outer wall of the L-shaped plate 7. The output end of the first motor 8 passes through the L-shaped plate 7 and is fixedly installed with a cam 9. A tank 10 is fixedly installed between the two movable plates 4.

[0023] The effect achieved by the entire embodiment 1 is that when the soil enters the tank 10, the staff starts the first motor 8. The output end of the first motor 8 drives the cam 9 to rotate. The cam 9 contacts the connecting plate 6 and pushes the connecting plate 6 to move. Then, the moving plate 4 drives one end of the tank 10. The springs 3 at both ends of the moving plate 4 are stretched or retracted. When the cam 9 is no longer in contact with the cam 9, the elastic force of the spring 3 drives the tank 10 to move in another direction. Back and forth, the tank 10 swings back and forth, which makes the soil dispersed and makes the soil distribution more uniform.

[0024] Example 2, as Figures 1-4 As shown, the tank body 10 further includes a storage slot 23 inside, a toothed ring 29 is rotatably installed inside the storage slot 23, a filter cylinder 26 is fixedly installed on the outer wall of the toothed ring 29, one end of the filter cylinder 26 penetrates the tank body 10, and multiple evenly distributed scrapers 28 are fixedly installed on the inner wall of the filter cylinder 26.

[0025] Furthermore, a second motor 24 is fixedly installed on the outer wall of the tank 10. The output end of the second motor 24 enters the storage slot 23 and a gear 25 is fixedly installed thereon. The gear 25 meshes with the gear ring 29.

[0026] Furthermore, a water pump 20 is fixedly installed on the outer wall of the tank 10, a fixed pipe 21 is fixedly installed on the inner wall of the tank 10, a plurality of evenly distributed nozzles 22 are fixedly installed at the bottom of the fixed pipe 21, a fixed plate 13 is fixedly installed on the outer wall of the tank 10, a water tank 14 is fixedly installed on the top of the fixed plate 13, and the output end of the water pump 20 is fixedly connected to the water tank 14.

[0027] Furthermore, a water inlet pipe 15 is fixedly installed on the top of the water tank 14, and a pipe cover 16 is provided on the top of the water inlet pipe 15 to facilitate the replenishment of the rinsing solution by the staff.

[0028] Furthermore, a tank cover 11 is provided at one end of the tank body 10, and flanges 12 are fixedly installed on both the tank cover 11 and the outer wall of the tank body 10. A sealing ring 18 is fixedly installed on the outer wall of the tank cover 11, and a sealing groove 17 is opened at one end of the tank body 10.

[0029] Furthermore, a vacuum pump 27 is fixedly installed on the outer wall of the tank 10. The input end of the vacuum pump 27 enters the tank 10. A water outlet pipe 19 is fixedly installed through the bottom of the tank 10. Before rinsing, the staff starts the vacuum pump 27 to extract the air inside the tank 10, forming a negative pressure environment to accelerate the penetration and diffusion of the rinsing solution in the soil.

[0030] The effect achieved by the entire embodiment 2 is that during rinsing, the staff starts the second motor 24, the output end of the second motor 24 drives the gear 25 to rotate, which in turn drives the gear ring 29 to rotate. The gear ring 29 drives the filter cylinder 26 to rotate, and when the scraper 28 rotates, it continuously lifts the soil, which facilitates the contact between the soil at the bottom and the rinsing liquid, and further improves the reaction efficiency.

[0031] Working principle: During use, the operator opens the tank lid 11, puts the soil into the filter cylinder 26, and then places the tank lid 11 next to the tank body 10. The two flanges 12 are then fixed together with bolts, and the sealing ring 18 is inserted into the sealing groove 17. This completes the installation and improves the sealing performance. When the soil enters the tank body 10, the operator starts the first motor 8. The output end of the first motor 8 drives the cam 9 to rotate. The cam 9 contacts the connecting plate 6, pushing the connecting plate 6 to move. This, in turn, moves one end of the tank body 10 through the moving plate 4. The springs 3 at both ends of the moving plate 4 stretch or retract. When the cam 9 is no longer in contact with the soil, the spring force of the spring 3 causes the tank body 10 to move in the other direction. This back-and-forth movement of the tank body 10 disperses the soil, making its distribution more uniform. During rinsing, the operator starts the second motor 24. The output of the second motor 24 drives the gear 25 to rotate, which in turn drives the gear ring 29 to rotate. The gear ring 29 drives the filter cylinder 26 to rotate. As the scraper 28 rotates, it continuously lifts the soil, facilitating contact between the soil at the bottom and the rinsing solution, further improving the reaction efficiency. The operator then starts the water pump 20, and the rinsing solution is sprayed from the nozzle 22 onto the soil, making contact with the soil. The rinsing solution then exits through the through-hole and finally leaves through the outlet pipe 19.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
