For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0021] Reference Figures 1 to 5In the embodiment of the utility model, a liquid phase stripping device for vermiculite nanosheets includes: a constant temperature box 1, a cover plate 2 is fixedly arranged above the constant temperature box 1, a stirring box 3 is fixedly arranged inside the constant temperature box 1, a feed pipe 4 is fixedly connected to one end above the stirring box 3, a liquid inlet pipe 5 is fixedly connected to the other end above the stirring box 3, a driving motor 6 is fixedly arranged at the other end above the stirring box 3, a stirring rod 7 is rotatably connected to the bottom of the driving motor 6, a stirring blade 8 is rotatably connected to the side of the stirring rod 7, an electric valve 9 is fixedly arranged below the stirring box 3, and a discharge pipe 10 is fixedly arranged below the electric valve 9.

[0022] The above scheme is adopted: the stirring box 3 is located inside the constant temperature box 1, and receives the raw material and the stripping liquid through the feed pipe 4 and the liquid inlet pipe 5 respectively, so that the raw material and the stripping liquid can be directly mixed in the stirring box 3, reducing the loss and pollution during the material transmission process. At the same time, the driving motor 6 drives the materials in the stirring box 3 through the stirring rod 7 and the stirring blade 8 to mix efficiently, thereby promoting the stripping reaction.

[0023] A first liquid pump 11 is fixedly connected to one side of the constant temperature box 1, a first water tank 12 is fixedly connected to the side of the first liquid pump 11, a water inlet port 13 is fixedly arranged above the first water tank 12, a second liquid pump 14 is fixedly arranged on the other side of the constant temperature box 1, a second water tank 15 is fixedly arranged on the side of the second liquid pump 14, a water tank support rod 16 is fixedly arranged below the first water tank 12 and the second water tank 15, a separation liquid tank 17 is fixedly arranged above the first water tank 12 and the second water tank 15, a liquid replenishment port 18 is fixedly arranged above the separation liquid tank 17, a side of the separation liquid tank 17 is fixedly connected to the liquid inlet pipe 5, a reflux pipe 19 is fixedly connected to the side of the first water tank 12, and the other side of the reflux pipe 19 is fixedly connected to the second water tank 15.

[0024] The above scheme is adopted: a circulating cooling or heating system is constructed through the first liquid pump 11 and the second liquid pump 14, and the first water tank 12 and the second water tank 15 connected thereto. This system can ensure that the temperature in the constant temperature box 1 remains constant, providing an ideal temperature environment for the stripping reaction in the stirring box 3. The water inlet port 13 allows cooled or heated water to be added to the first water tank 12, and the reflux pipe 19 realizes the circulation of water between the two water tanks, ensuring that the temperature in the constant temperature box 1 is uniform and stable.

[0025] A raw material box 20 is fixedly connected above the feed pipe 4 , a feed port 21 is fixedly arranged above the raw material box 20 , an ultrasonic separation device 22 is fixedly connected below the feed pipe 10 , and a control panel 23 is fixedly arranged on the side of the ultrasonic separation device 22 .

[0026] With the above solution, the discharge port 21 above the raw material box 20 allows the raw materials to enter the feed pipe 4 at the required amount and speed, and then be transported to the mixing box 3 for processing, thereby ensuring the continuity and stability of the raw material supply and reducing pollution and waste during the operation.

[0027] There are multiple groups of stirring boxes 3, the driving motor 6 is rotatably connected to the stirring rod 7 through the top of the stirring box 3, the electric valve 9 is fixedly connected to the stirring box 3 through the bottom of the constant temperature box 1, and a certain gap is left between the multiple groups of stirring boxes 3 inside the constant temperature box 1, so that water can be injected into the internal gap of the constant temperature box 1 to adjust the temperature of the outside of the stirring box 3.

[0028] The above scheme is adopted: by arranging multiple groups of stirring boxes 3 inside the thermostatic box 1, multiple batches of vermiculite nanosheets can be peeled off at the same time, which not only improves production efficiency, but also reduces equipment idle rate, making the overall operation more efficient. Each stirring box 3 is equipped with an independent drive motor 6 and a stirring rod 7 to ensure that each batch of processing can be fully stirred and mixed, thereby ensuring the quality and consistency of the product. Certain gaps are left between the multiple groups of stirring boxes 3 inside the thermostatic box 1. These gaps can be used to inject water. The water can flow through the outside of the stirring box 3 to adjust the temperature of the stirring box 3, so that the temperature adjustment is more uniform and efficient, and the stability and reliability of the system are further improved.

[0029] The internal water source of the constant temperature box 1 is pumped into the first water tank 12 through the first liquid pump 11, and the second liquid pump 14 discharges the internal water source of the constant temperature box 1 into the second water tank 15. The internal water source of the second water tank 15 enters the first water tank 12 through the reflux pipe 19, and the liquid inlet pipe 5 is connected to the separation liquid tank 17 through the top of the cover plate 2. There are two groups of separation liquid tanks 17.

[0030] With the above solution, the separation liquid tank 17 provides a stable and continuous supply of separation liquid for the stripping reaction. The liquid replenishment port 18 allows the operator to add new separation liquid to the separation liquid tank 17 as needed to ensure the continuity and stability of the reaction. At the same time, the separation liquid tank 17 is directly connected to the stirring tank 3 through the liquid inlet pipe 5, which simplifies the separation liquid delivery process and reduces possible contamination and loss.

[0031] The feed pipe 4 is fixedly connected to the raw material box 20 through the top of the cover plate 2 . The raw material box 20 is located directly above the constant temperature box 1 , and the ultrasonic separation device 22 is located directly below the constant temperature box 1 .

[0032] According to the above scheme, the mixture in the mixing box 3 flows into the ultrasonic separation device 22 through the electric valve 9 and the feeding pipe 10. The ultrasonic separation device 22 utilizes the high-frequency vibration of ultrasound to quickly and effectively separate the vermiculite nanosheets from the liquid.

[0033] The working principle of the utility model is as follows: first, the vermiculite particles are placed in the raw material box 20, and the raw materials are transported to the stirring box 3 through the feed port 21 and the feed pipe 4. At the same time, the liquid used for liquid phase stripping is stored in the separation liquid box 17, and is kept sufficient through the liquid replenishment port 18. The separation liquid is introduced into the stirring box 3 through the liquid inlet pipe 5 to mix with the raw materials. Next, the driving motor 6 is started to drive the stirring rod 7 and the stirring blade 8 to rotate in the stirring box 3. This rotational motion ensures that the raw materials and the separation liquid are fully mixed, and promotes the liquid phase stripping reaction. At the same time, the water in the thermostatic box 1 is extracted from the first water tank 12 by the first liquid pump 11, and circulated to the second liquid pump 14 and the reflux pipe 19. In the second water tank 15, the temperature around the stirring box 3 is kept constant to ensure that the liquid-phase stripping reaction is carried out under the optimal temperature conditions. When the liquid-phase stripping reaction is completed, the electric valve 9 is opened, and the stripped mixture flows into the ultrasonic separation device 22 through the feed pipe 10. The ultrasonic separation device 22 uses the effect of ultrasonic waves to separate the stripped vermiculite nanosheets from the liquid. This process is monitored and operated through the control panel 23, and the stirring speed, temperature setting, and valve switching can be accurately controlled. A plurality of groups of stirring boxes 3 are provided in the device, which can process multiple batches of raw materials at the same time to improve production efficiency. Each group of stirring boxes 3 is equipped with an independent drive motor 6 and an electric valve 9, which can be independently controlled.

[0034] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
