Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and in particular to a soil remediation device that combines rinsing and solidification. Background Technology

[0002] With the acceleration of industrialization and urbanization, soil pollution has become increasingly serious, posing a severe threat to the ecological environment and human health. As an important soil remediation method, the combined leaching and solidification technology has significant advantages in treating soils with various types of pollution, such as heavy metals and organic pollutants, and has therefore received widespread attention and application.

[0003] In traditional leaching and solidification combined soil remediation equipment, the leaching solution is usually discharged directly or after simple treatment after the leaching operation is completed. This not only causes a huge waste of water resources, but may also lead to secondary pollution problems. Since the leaching solution often contains pollutants that have not been completely removed, if it is discharged directly, these pollutants will enter water bodies, soil and other environmental media, further spreading the pollution range. At the same time, the use of a large amount of fresh leaching agent increases the remediation cost, making the economic burden of soil remediation work heavier. Therefore, a leaching and solidification combined soil remediation equipment is proposed to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-5 A soil remediation device combining leaching and solidification includes a box body 1. A crushing component and a sorting and storage component are respectively installed on the top side of the box body 1. Connecting plates 9 are fixedly installed on both inner walls of the box body 1. A tank body 10 is fixedly connected between the two connecting plates 9. A mixing component is installed inside the tank body 10. A first bevel gear 18 is installed in the tank body 10 through the mixing component. A lead screw 19 is installed inside the box body 1. The two ends of the lead screw 19 are rotatably connected to the inner walls of both sides of the box body 1. A second bevel gear 20 is fixedly sleeved on the outer side of the lead screw 19, and the second bevel gear 20 meshes with the first bevel gear 18. Two guide rods 21 are fixedly installed on the inner wall of the box body 1. A slider 22 is slidably sleeved on the outer side of the two guide rods 21 and the lead screw 19. Multiple brushes are provided on the bottom side of the slider 22. The bottom inner wall of the box body 1 is fixedly equipped with... The system includes a collection box 23 containing a filter plate 24. Multiple brushes on the bottom side of a slider 22 contact the top side of the filter plate 24. A circulation assembly is installed inside the main body 1. A first bevel gear 18 meshes with a second bevel gear 20. Under the transmission of the first bevel gear 18, the second bevel gear 20 drives the lead screw 19 to rotate. This causes the slider 22, which is slidably sleeved on the outside of the lead screw 19, to move the brushes at the bottom back and forth, cleaning the impurities and contaminants accumulated on the surface of the filter plate 24. This prevents contaminants from clogging the filter plate and ensures its filtration effect. The filter plate 24 filters impurities in the rinsing agent, and the filtered rinsing agent accumulates at the bottom of the collection box 23 along the filter plate 24, facilitating subsequent recycling.

[0024] according to Figure 1 , Figure 2 and Figure 4As shown, the crushing assembly includes a crushing box 2 fixedly installed on the top side of the main body 1. A first motor 3 is fixedly installed on one side of the crushing box 2. The output end of the first motor 3 rotatably passes through the crushing box 2 and is fixedly sleeved with a first gear 4. A circular hole is opened on one side of the crushing box 2, and a rotating rod 5 is arranged in the circular hole. One end of the rotating rod 5 is rotatably connected to the inner wall of one side of the crushing box 2, and a second gear 6 is fixedly sleeved on the other end of the rotating rod 5. The second gear 6 meshes with the first gear 4. Crushing wheels 7 are fixedly sleeved on the outer sides of the rotating rod 5 and the output end of the first motor 3. A funnel 8 is fixedly connected to the bottom side of the crushing box 2, and the funnel 8 faces towards... The tank body 10 is equipped with two crushing wheels 7. When carrying out contaminated soil remediation work, the first motor 3 is started first, which drives the first gear 4 to rotate. Since the first gear 4 and the second gear 6 mesh with each other, the second gear 6 drives the rotating rod 5 to rotate synchronously under the drive of the first gear 4. This causes the rotating rod 5 and the crushing wheel 7, which is fixedly sleeved on the outside of the output end of the first motor 3, to rotate relative to each other. The contaminated soil is placed in the crushing box 2, and the two relatively rotating crushing wheels 7 can crush the soil. The crushed soil is more likely to come into contact with the leaching agent. With the help of the funnel 8, the crushed soil can be transported into the tank body 10.

[0025] according to Figure 1 , Figure 2 and Figure 5 As shown, the classification and storage component includes a first box 11 and a second box 12 fixedly installed on the top side of the box body 1. Discharge pipes 13 are fixedly installed on the bottom sides of both the first box 11 and the second box 12, with the other ends of both discharge pipes 13 facing the tank body 10. A first solenoid valve 14 is fixedly sleeved on the outside of each of the two discharge pipes 13. The first box 11 contains lime. When there is no residue or only a small amount of leaching liquid in the tank body 10, the first solenoid valve 14 below the first box 11 is opened, allowing the lime in the first box 11 to enter the tank body 10 through the discharge pipes 13. At this time, multiple stirring rods 17 will thoroughly stir the lime and soil, ensuring more complete contact between the lime and pollutants and soil particles. Furthermore, the thorough stirring by the stirring rods 17 ensures that the lime is evenly distributed throughout the soil sample, guaranteeing that each part of the soil receives proper solidification treatment, resulting in a more uniform and consistent quality of the remediated soil.

[0026] according to Figure 1-3As shown, the mixing assembly includes a fixed plate 15 fixedly installed inside the tank body 10. A second motor 16 is fixedly installed on the top side of the fixed plate 15. The output end of the second motor 16 rotates through the fixed plate 15 and the tank body 10. A first bevel gear 18 is fixedly connected to the output end of the second motor 16. Multiple stirring rods 17 are fixedly installed on the outside of the output end of the second motor 16. A connecting pipe 25 is fixedly installed on the bottom side of the tank body 10. The other end of the connecting pipe 25 faces the collection box 23. A filter screen 26 is provided inside the connecting pipe 25. A cleaning plate 27 is fixedly installed on the outside of the output end of the second motor 16. Multiple brushes are fixedly installed on the bottom side of the cleaning plate 27. The multiple brushes interact with the tank body. The bottom inner wall of the main body 10 is in contact with the second motor 16, which drives the multiple stirring rods 17 fixedly installed on its outer side to rotate, thereby fully mixing the soil and the leaching agent. Since the soil has been broken before entering the tank body 10, the leaching agent can come into contact with the soil more effectively, thereby separating the pollutants in the soil. The filter screen 26 installed in the connecting pipe 25 can prevent the soil from entering the collection box 23 along with the leaching agent. In addition, the cleaning plate 27 installed during the operation of the second motor 16 will have its bottom brush clean the soil attached to the surface of the filter plate 24 at the same time, preventing the leaching agent from being blocked due to soil clogging the filter screen 26.

[0027] according to Figure 2 and Figure 5 As shown, the circulation assembly includes a circulation pump 30 fixedly installed on the bottom inner wall of the tank body 10. An extraction pipe 31 is fixedly installed on one side of the circulation pump 30. The other end of the extraction pipe 31 is fixedly connected to one side of the collection box 23 and communicates with the collection box 23. A delivery pipe 32 is fixedly installed on the other side of the circulation pump 30. The other end of the delivery pipe 32 passes through the tank body 1 and is fixedly connected to one side of the second tank body 12. The delivery pipe 32 communicates with the second tank body 12. By setting up the circulation pump 30, when all the rinsing agent in the tank body 10 enters the collection box 23, the circulation pump 30 is started, driving the extraction pipe 31 to extract the filtered rinsing agent and transport it back to the second tank body 12 through the delivery pipe 32, so as to realize the recycling of the rinsing agent.

[0028] according to Figure 2 and Figure 3 As shown, a discharge port 28 is provided on the bottom side of the tank body 10, and a second solenoid valve 29 is provided on the outside of the discharge port 28. By providing the second solenoid valve 29, when the soil in the tank body 10 reacts and solidifies with lime, the second solenoid valve 29 can be opened to allow the solidified soil to be discharged from the discharge port 28.

[0029] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0030] In use: When remediation of contaminated soil is required, the first motor 3 is started to drive the first gear 4 to rotate. Because the first gear 4 meshes with the second gear 6, the second gear 6 synchronously drives the rotating rod 5 to rotate under the transmission of the first gear 4. This causes the rotating rod 5 and the crushing wheel 7, which is fixedly sleeved on the outer side of the output end of the first motor 3, to rotate relative to each other. During the relative rotation, the contaminated soil is placed in the crushing box 2, so that the two relatively rotating crushing wheels 7 can crush the soil. After crushing, it is easy to contact with the leaching agent. Through the funnel 8, the crushed soil can be transported into the tank body 10. Then, by activating the first solenoid valve 14 on the bottom side of the second box 12, the leaching agent in the second box 12 can be activated. The washing agent is delivered into the tank body 10 through a discharge pipe 13. Upon entering the tank body 10, the second motor 16 drives multiple externally fixed stirring rods 17, ensuring thorough mixing of the soil and washing agent. Because the soil has been broken up before entering the tank body 10, the washing agent can better contact the soil, thus separating contaminants. A connecting pipe 25 is used to deliver the washing agent from the tank body 10 to the collection box 23. The collection box 23 is equipped with a filter plate 24, which blocks fine impurities and contaminants. The washing agent filtered by the filter screen 26 accumulates at the bottom of the collection box 23. The filter screen 26 installed inside the connecting pipe 25 prevents soil from entering the collection box 23 along with the leaching agent. The cleaning plate 27, during the operation of the second motor 16, simultaneously drives the brush on the bottom side of the cleaning plate 27 to clean the soil adhering to the surface of the filter screen 26, preventing soil blockage that could hinder the leaching agent discharge. Furthermore, the presence of a first bevel gear 18, which meshes with a second bevel gear 20, causes the second bevel gear 20 to simultaneously drive the lead screw 19 to rotate. This, in turn, causes the slider 22, which is slidably connected to the outside of the lead screw 19, to move the brush on the bottom side back and forth, cleaning the impurities and contaminants accumulated on the surface of the filter plate 24, preventing contamination. If pollutants become clogged at a certain point, the filtration effect of the filter screen 26 will deteriorate. When all the leaching agent in the tank body 10 enters the collection box 23, the circulation pump 30 drives the extraction pipe 31 to extract the filtered leaching agent. The leaching agent is then transported to the second tank 12 through the delivery pipe 32, thus achieving recycling. A first tank 11 is provided, containing lime. When there is no residue or only a small amount of leaching liquid remaining in the tank body 10, the first solenoid valve 14 below the first tank 11 is opened, allowing the lime in the first tank 11 to be transported to the tank body 10 through the discharge pipe 13. When the lime enters the tank body 10, multiple stirring rods 17 thoroughly mix the lime and soil.Lime can come into more thorough contact with pollutants and soil particles, and the mixing rod 17 ensures thorough mixing, allowing the lime to be evenly distributed throughout the soil sample. This guarantees that each part of the soil receives appropriate solidification treatment, resulting in a more uniform and consistent quality of the remediated soil.
