Description

Technical Field

[0001] The utility model relates to the technical field of soil remediation, and particularly relates to a soil chemical leaching device. Background Technique

[0002] Soil is a natural resource on the earth's surface, which is jointly composed of minerals, organic matter, water, air and organisms. It is the basis for plant growth and also plays an important role in the ecosystem. Soil remediation refers to the restoration of polluted or degraded soil through physical, chemical and biological methods, so that it can support plant growth and ecosystem functions again. Soil remediation is crucial for environmental protection, agricultural production and public health. Soil chemical leaching is a soil remediation technology. By adding chemical reagents to the polluted soil, pollutants are dissolved or suspended in the liquid, and then the solution containing pollutants is leached out of the soil. This method is particularly suitable for removing heavy metals and organic pollutants. The prior art cannot ensure that the soil fully contacts the cleaning liquid, resulting in low cleaning efficiency, unsatisfactory cleaning effect, and the cleaning liquid in the cleaning process is not fully utilized or wasted in large quantities, increasing the cleaning cost and resource waste. Content of the Utility Model

[0003] The utility model provides a soil chemical leaching device, which solves the above-mentioned technical problems.

[0004] The solutions of the utility model to solve the above technical problems are as follows:

[0005] A soil chemical leaching device includes a guide groove, a cleaning groove, a groove and a support plate. A guide groove is opened in the cleaning groove. A groove is opened below the guide groove in the cleaning groove. A rotating shaft is rotatably installed in the groove. An auger is provided on the rotating shaft. One side of the cleaning groove is movably installed with a fixing plate through a cylinder. A motor is fixed on the fixing plate, and the output end of the motor is in transmission connection with the rotating shaft. A feeding pipe is provided at one end of the cleaning groove.

[0006] On the basis of the above technical solutions, the utility model can be further improved as follows.

[0007] Further, the feeding pipe is located at one end of the cleaning groove close to the support plate.

[0008] The beneficial effect of adopting the above further solution is:

[0009] Since the blanking pipe is located at the higher end of the cleaning tank, by using gravity, the cleaning liquid in the washed soil can naturally flow back, separating quickly from the soil. This design can effectively prevent the cleaning liquid from remaining in the soil, reduce the water content of the soil, ensure the quality of the cleaned soil, while reducing the loss of the cleaning liquid, lowering the consumption of the cleaning liquid during the cleaning process, facilitating the saving of the cleaning cost, and improving the cleaning efficiency.

[0010] Furthermore, the guiding groove is arc-shaped and symmetrically distributed on both sides of the groove.

[0011] The beneficial effect of adopting the above further scheme is:

[0012] The arc-shaped design of the guiding groove helps to evenly guide the flow of the soil in the cleaning tank. The soil will flow under the action of the cleaning liquid, and the arc-shaped guiding groove can enable the soil to form a good circulating flow path in the cleaning tank, preventing the local accumulation of the cleaning liquid in the cleaning tank, effectively avoiding dead corners in the cleaning tank. The flow path of the soil in the cleaning tank is smoother, without dead corners in local areas, reducing the possibility of the soil not being cleaned, and ensuring the uniformity and thoroughness of the cleaning effect.

[0013] Furthermore, one end of the cleaning tank is provided with a support plate, and the cylinder is installed on the support plate.

[0014] The beneficial effect of adopting the above further scheme is:

[0015] Installing the cylinder on the support plate can not only conveniently fix the cylinder, but also enable the cylinder to be closely connected to the overall structure of the cleaning tank, making the installation more firm, and reducing the possible movement or loosening during the installation process.

[0016] Furthermore, the cleaning tank is inclined, and the end of the cleaning tank where the cylinder is installed is the higher end.

[0017] The beneficial effect of adopting the above further scheme is:

[0018] The inclined setting of the cleaning tank helps to promote the drainage of the cleaning liquid and moisture. Since one end of the cleaning tank is higher, the cleaning liquid and moisture will naturally flow along the inclined direction to the lower end, facilitating the reflux of the cleaning liquid, reducing the loss of the cleaning liquid, lowering the consumption of the cleaning liquid during the cleaning process, facilitating the saving of the cleaning cost, and improving the cleaning efficiency.

[0019] Furthermore, the cylinder drives the motor through a fixing plate, and then drives the rotating shaft to move back and forth in the groove.

[0020] The beneficial effect of adopting the above further scheme is:

[0021] The forward and backward movement of the rotating shaft can not only make the cleaning liquid fully contact with the soil, but also promote the mixing and stirring of the soil, accelerate the dissolution and release of pollutants in the soil during the cleaning process, improve the cleaning efficiency, shorten the cleaning time, and improve the use efficiency of the equipment. When the cleaning is completed, the telescopic rod of the cylinder reciprocates, pushing the fixed plate and the motor to move the auger forward and backward to complete the lifting and discharge of the soil.

[0022] Furthermore, the size of the auger is adapted to the size of the groove.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] The matching of the size of the auger and the groove can ensure that the auger completely covers the soil in the groove, so that the soil can fully contact the surface of the auger. This can increase the contact area between the soil and the cleaning liquid, improve the cleaning efficiency, make the cleaning more thorough, and more effectively use the cleaning liquid and cleaning energy, reduce the waste of cleaning liquid, and reduce the energy consumption during the cleaning process.

[0025] Furthermore, the cylinder is provided with one or more.

[0026] The beneficial effects of adopting the above further scheme are:

[0027] The multiple cylinders can enhance the stability of the device. The multiple cylinders can provide a more balanced support force, reduce the shaking and instability of the device during the cleaning process, and improve the safety and stability of the device.

[0028] The beneficial effects of the utility model are:

[0029] The size of the auger is adapted to the groove to ensure that the soil rolls and stirs in the groove. The rotation of the auger drives the soil to roll continuously in the cleaning liquid, so that every part of the soil can fully contact the cleaning liquid, improving the cleaning efficiency and effect. The cleaning tank is equipped with arc-shaped guide grooves, which are symmetrically distributed on both sides of the groove. The arc-shaped design helps to guide the flow of soil in the tank, ensuring that the soil can form a good circulation flow path in the cleaning tank, avoiding dead corners, and ensuring that the soil is cleaned evenly and thoroughly.

[0030] The cylinder is in a retracted state during the cleaning process, driving the fixed plate and the motor, thereby driving the shaft and the auger to tumble and clean. When the cleaning is completed, the telescopic rod of the cylinder reciprocates, pushing the fixed plate and the motor, causing the auger to move forward and backward to complete the soil lifting and discharge. This automated design reduces manual operation and improves work efficiency. The motor is installed on the fixed plate, and the output end is connected to the shaft transmission. The rotation of the motor drives the auger to rotate, achieving soil mixing and lifting. The cooperation of the motor and the cylinder makes the entire cleaning and discharge process automated and easy to operate.

[0040] Please refer to Figures 1 to 3 as shown, the embodiments provided by the present utility model are as follows:

[0041] Embodiment 1

[0042] A soil chemical leaching device includes a guiding groove 3, a cleaning tank 4, a groove 5 and a support plate 7. A guiding groove 3 is provided in the cleaning tank 4. The guiding groove 3 is arc-shaped and symmetrically distributed on both sides of the groove 5. The arc-shaped design of the guiding groove 3 helps to evenly guide the flow of soil in the cleaning tank 4. Under the action of the cleaning liquid, the soil will flow. The arc-shaped guiding groove 3 can enable the soil to form a good circulating flow path in the cleaning tank 4, avoiding the local accumulation of the cleaning liquid in the cleaning tank 4 and effectively avoiding dead corners in the cleaning tank 4. The flow path of the soil in the cleaning tank 4 is smoother, without dead corners in local areas, reducing the possibility that the soil is not cleaned, ensuring the uniformity and thoroughness of the cleaning effect. A groove 5 is provided below the guiding groove 3 in the cleaning tank 4. A rotating shaft 2 is rotatably installed in the groove 5. A screw conveyor 1 is provided on the rotating shaft 2. The screw conveyor 1 is adapted to the size of the groove 5. The screw conveyor 1 being adapted to the size of the groove 5 can ensure that the screw conveyor 1 completely covers the soil in the groove 5, enabling the soil to fully contact the surface of the screw conveyor 1. This can increase the contact area between the soil and the cleaning liquid, improve the cleaning efficiency, make the cleaning more thorough, make more effective use of the cleaning liquid and cleaning energy, reduce the waste of the cleaning liquid, and reduce the energy consumption during the cleaning process. One side of the cleaning tank 4 is movably installed with a fixing plate 8 through a cylinder 6. There is one or more cylinders 6. During cleaning, the cylinder 6 is in a contracted state, enabling the screw conveyor 1 to drive the soil to tumble and clean in the groove 5. Having multiple cylinders 6 can enhance the stability of the device. Multiple cylinders 6 can provide a more balanced supporting force, reducing the shaking and instability of the device during cleaning, and improving the safety and stability of the device. One end of the cleaning tank 4 is provided with a support plate 7. The cylinder 6 is installed on the support plate 7. Installing the cylinder 6 on the support plate 7 can not only conveniently fix the cylinder 6, but also enable the cylinder 6 to be closely connected to the overall structure of the cleaning tank 4, with a more secure installation, reducing the possible movement or loosening during the installation process. The cleaning tank 4 is inclined, and the end of the cleaning tank 4 where the cylinder 6 is provided is the higher end. The inclined setting of the cleaning tank 4 helps to promote the drainage of the cleaning liquid and moisture.Since one end of the cleaning tank 4 is higher, the cleaning liquid and water will naturally flow in the inclined direction towards the lower end, facilitating the reflux of the cleaning liquid, reducing the loss of the cleaning liquid, lowering the consumption of the cleaning liquid during the cleaning process, being conducive to saving the cleaning cost and improving the cleaning efficiency. A motor 9 is fixed on the fixing plate 8, and the output end of the motor 9 is in transmission connection with the rotating shaft 2. The air cylinder 6 drives the motor 9 through the fixing plate 8, and then drives the rotating shaft 2 to move back and forth in the groove 5. After the cleaning is completed, the telescopic rod of the air cylinder 6 reciprocates, pushing the fixing plate 8 through the air cylinder 6. The fixing plate 8 drives the motor 9 to move, and then makes the auger 1 reciprocate to lift the soil after cleaning to the blanking pipe 10 for blanking. The forward and backward movement of the rotating shaft 2 can not only make the cleaning liquid fully contact with the soil, but also promote the mixing and stirring of the soil, accelerating the dissolution and release of pollutants in the soil during the cleaning process, improving the cleaning efficiency, shortening the cleaning time, and enhancing the usage efficiency of the equipment. And after the cleaning is completed, the telescopic rod of the air cylinder 6 reciprocates, pushing the fixing plate 8 and the motor 9 to make the auger 1 move back and forth to complete the soil lifting and discharging. A blanking pipe 10 is provided at one end of the cleaning tank 4, and the blanking pipe 10 is located at one end of the cleaning tank 4 close to the support plate 7. Since the blanking pipe 10 is located at the higher end of the cleaning tank 4, by using gravity, the cleaning liquid in the cleaned soil can naturally flow back and be quickly separated from the soil. This design can effectively prevent the cleaning liquid from remaining in the soil, reduce the soil moisture content, ensure the quality of the cleaned soil, and at the same time reduce the loss of the cleaning liquid, lower the consumption of the cleaning liquid during the cleaning process, being conducive to saving the cleaning cost and improving the cleaning efficiency.

[0043] When a soil chemical leaching device based on Embodiment 1 is in use:

[0044] The auger 1 is adapted to the size of the groove 5 to ensure that the soil tumbles and stirs in the groove. The rotation of the auger drives the soil to continuously tumble in the cleaning liquid, enabling every part of the soil to fully contact the cleaning liquid, improving the cleaning efficiency and effect. An arc-shaped guiding groove 3 is provided in the cleaning tank 4, and the guiding grooves 3 are symmetrically distributed on both sides of the groove 5. The arc-shaped design helps to guide the flow of the soil in the tank, ensuring that the soil can form a good circulating flow path in the cleaning tank, avoiding dead corners, and ensuring uniform and thorough soil cleaning.

[0045] The air cylinder 6 is in a contracted state during the cleaning process, driving the fixing plate 8 and the motor 9, thereby driving the rotating shaft 2 and the auger 1 to perform tumbling cleaning. After the cleaning is completed, the telescopic rod of the air cylinder 6 reciprocates, pushing the fixing plate 8 and the motor 9 to make the auger 1 move back and forth to complete the soil lifting and discharging. This automated design reduces manual operation and improves work efficiency. The motor 9 is installed on the fixing plate 8, and the output end is in transmission connection with the rotating shaft 2. The rotation of the motor drives the auger 1 to rotate to achieve the stirring and lifting of the soil. The cooperation of the motor and the air cylinder makes the entire cleaning and discharging process automated and easy to operate.
