Description

Technical Field

[0002] Graphene aerogels are lightweight, porous materials composed of graphene, combining the excellent properties of graphene, such as high electrical conductivity, excellent mechanical strength, and outstanding thermal stability, with the low density and high specific surface area of ​​aerogels. This makes graphene aerogels extremely promising for applications in energy storage, thermal management, and environmental remediation. Current methods for the mass production of graphene aerogels mainly include chemical vapor deposition (CVD), freeze-drying, and supercritical drying. Typical preparation processes involve placing graphene oxide hydrogels in a specific template and obtaining aerogels through drying and reduction. However, these traditional methods suffer from problems such as cumbersome operation steps, long drying and reduction processes, low yields, and high costs, limiting their large-scale application and continuous production outside the laboratory.

[0022] To address the problem of low efficiency in the preparation of graphene aerogels in existing technologies, this application provides a continuous graphene aerogel preparation apparatus.

[0023] See Figure 1 The continuous graphene aerogel preparation device includes a liquid inlet assembly 10, a reaction vessel 20, a spray assembly 30, a clamp 40, and a liquid drain assembly 50. The reaction vessel 20 has a reaction space inside, and the container wall of the reaction vessel 20 has a liquid inlet channel, which is connected to the liquid inlet assembly 10. The spray assembly 30 is installed on the container wall of the reaction vessel 20 and is connected to the liquid inlet channel. The clamp 40 is detachably placed in the placement space and provides an area for placing raw materials. The liquid drain assembly 50 is connected to the reaction space.

[0024] In the production of graphene aerogels, the raw material is placed on a fixture 40, which is then placed inside a reaction vessel 20. The reaction liquid from the liquid inlet assembly 10 is sprayed onto the raw material through a spray assembly 30, resulting in a semi-finished product. The fixture 40 and the raw material are then removed from the reaction vessel 20, and a new fixture 40 and raw material are placed in place. The semi-finished product is then placed on other equipment for drying to obtain the finished product. This method of processing the raw material improves the preparation efficiency of graphene aerogels, reduces production costs, and is suitable for large-scale industrial production.

[0025] In this application, the clamp 40 has an upper connecting rod 41 and a lower connecting rod 42, and the raw material is alternately wound on the upper connecting rod 41 and the lower connecting rod 42. The clamp 40 includes a frame, and both the upper connecting rod 41 and the lower connecting rod 42 are connected to the frame.

[0026] Specifically, the frame is a framework structure composed of multiple interconnected rods, with upper connecting rod 41 and lower connecting rod 42 located at the top and bottom of the frame, respectively. The raw material is wound alternately through upper connecting rod 41 and lower connecting rod 42, which increases the area of ​​the raw material spread. During spraying, this maximizes the reaction area between the raw material and the reaction liquid sprayed by the spraying component 30, thereby increasing the reaction efficiency and improving the reaction effect.

[0027] In this application, a fastener is provided on the inner wall of the reactor 20, and the fastener is connected to the frame.

[0028] Since the raw material is wound on the clamp 40, gaps are required between the top and bottom of the clamp 40 and the reactor 20. Therefore, fixing members need to be installed on the inner wall of the reactor 20 to support the clamp 40, ensuring a distance between the bottom of the clamp 40 and the bottom of the reactor 20, thereby improving the reaction effect. Multiple fixing members can be provided, spaced apart along the circumferential direction of the reactor 20. Multiple fixing members working together support the frame, improving the stability of the clamp 40 within the reactor 20.

[0029] In this application, the reactor 20 includes a filter screen 21, which is disposed at the bottom of the reactor 20, and the drain assembly 50 is connected to the bottom of the reactor 20 through the filter screen 21.

[0030] The filter screen 21 reduces the amount of raw material residue entering the drainage component 50, improves the purity of the waste liquid, facilitates subsequent treatment, reduces the impact on the environment, and is suitable for production environments with high environmental protection requirements.

[0031] In this application, the reactor 20 includes a filter screen 21, which is disposed at the bottom of the reactor 20. The graphene aerogel continuous preparation device also includes a reflux pipeline 60, one end of which is connected to the liquid inlet assembly 10, and the other end of which is connected to the bottom of the reactor 20.

[0032] The design of the reflux pipeline 60 enables the recycling of the reaction solution, reducing production costs and improving resource utilization. Furthermore, the filter screen 21 installed at the bottom of the reactor 20 can filter out residues generated during the spraying process, facilitating the recovery and reuse of the reaction solution.

[0033] In one embodiment, the filter 21 is detachably disposed inside the reactor 20.

[0034] Specifically, this design facilitates the replacement and cleaning of the filter screen 21, ensuring long-term stable operation of the equipment. Simultaneously, it allows for the replacement of different types of filter screens 21 based on the actual size of the generated impurity particles, reducing the occurrence of filter screen 21 clogging. Preferably, to facilitate the detachable design of the filter screen 21, a sliding groove is provided at the bottom of the reactor 20. The filter screen 21 has a frame, and the frame of the filter screen 21 slides within the sliding groove. This sliding arrangement of the filter screen 21 frame and the sliding groove facilitates the replacement of the filter screen 21. Alternatively, at least a portion of the bottom of the reactor 20 is detachably connected to the reactor 20 body. The filter screen 21 is laid on the bottom of the reactor 20. When the filter screen 21 needs to be replaced, the detachable portion of the bottom of the reactor 20 is disassembled to replace the filter screen 21.

The liquid inlet mixing tank 12 stirs the reaction solution and sends it into the liquid inlet channel of the reaction vessel 20.

[0038] The drainage assembly 50 includes a drainage mixing tank 52 and a drainage storage tank 51. The drainage mixing tank 52 is connected to the reactor 20 and is used to receive the waste liquid after the reaction in the reactor 20 is completed. The drainage storage tank 51 is connected to the drainage mixing tank 52.

[0039] The solution stored in the inlet storage tank 11 has a high concentration. Before spraying the raw materials, the reaction solution needs to be diluted. The solution and deionized water are injected together into the inlet mixing tank 12 for mixing and further dilution. Different concentrations of reaction solution can be prepared according to the requirements of the raw materials. After cleaning, the deionized water used to wash the raw materials enters the outlet mixing tank 52 for centralized treatment.

[0040] In this application, a heating device is provided at the bottom of the liquid mixing tank 12, and a stirring blade that is rotatably connected to the liquid mixing tank 12 is provided inside the liquid mixing tank 12.

[0051] Operation Process: When current is applied to the device, the inlet storage tank 11 and water storage tank 70 are connected to the inlet mixing tank 12 according to the set program. The flow valve on the pipeline automatically opens, and the reaction liquid in the inlet storage tank 11 and the deionized water in the water storage tank 70 are injected into the inlet mixing tank 12 in a certain proportion. Then, the flow valve on the connecting pipeline automatically closes. The servo motor on the top of the inlet mixing tank 12 is then automatically turned on, the stirring speed is set to 2500 r / min, the stirring time is 30 min, the heating device is turned on, the temperature is set to 50℃, and stirring begins after the temperature stabilizes. After stirring is completed, the flow valve on the connecting pipeline between the inlet mixing tank 12 and the reaction vessel 20 is automatically opened, and all the mixed reaction liquid in the inlet mixing tank 12 is injected into the inlet channel on the inner wall of the reaction vessel 20.
