Description

Technical Field

[0001] The invention relates to the technical field of graphene production, in particular to graphene drying equipment. Background Art

[0002] Graphene is an allotrope of carbon. Carbon atoms are bonded in sp² hybridization to form a single-layer hexagonal honeycomb lattice graphene. Stacked graphene layers form graphite. Graphene has excellent optical, electrical, and mechanical properties. It has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery. It is considered to be a revolutionary material in the future. In the preparation of graphene, drying is a very critical step. In the process of preparing graphene by chemical vapor deposition, the reaction product contains a large amount of gas, solution, and impurities. These impurities will have a great impact on the quality of graphene. Therefore, it is necessary to remove the moisture and solvent in the impurities through drying equipment.

[0003] Existing devices mainly use freeze drying technology to remove water from graphene. Freeze drying, also known as sublimation drying, is a drying method that freezes water-containing materials below freezing point to convert water into ice, and then converts ice into steam under a relatively high vacuum to remove the water. The material can be frozen in a freezing device before drying, or it can be directly frozen in a drying chamber by quickly evacuating it, and the water vapor generated by sublimation is removed through a condenser.

[0004] The existing device mainly uses a freeze dryer to dry the graphene powder. The existing technology is similar to a graphene alloy powder preparation and drying device. The structure of the patent number CN116294446A includes a freezing chamber, a refrigeration device and a vacuum pump. The interior of the freezing chamber is evenly fixed with a freezing mold tube, and the upper surface of the freezing chamber is fixedly installed with a slurry feeding chamber, and the top of the freezing mold tube is connected to the inner cavity of the slurry feeding chamber. Through the setting of the freezing mold tube and the limit ring, the freezing and vacuum sublimation of the graphene alloy powder slurry during the freeze-drying process are distinguished, and the graphene alloy powder slurry is frozen into a solid. Then, under the vacuum negative pressure of the vacuum box, the solid is sucked from the freezing mold tube into the vacuum box, and then the solid ice in the solid is sublimated to complete the extraction of the graphene alloy powder, so that the two can be carried out at the same time, thereby effectively shortening the freeze-drying time and improving the efficiency of graphene alloy powder preparation and drying. However, there are still areas that can be optimized in this device.

[0005] The existing devices mainly use freeze dryers to dry large-grained graphene blocks, which makes it difficult for some devices to break frozen and adhered graphene blocks into graphene powders with smaller particle sizes, which makes it inconvenient to volatilize the moisture inside the graphene raw materials. Secondly, some devices mainly perform sublimation drying on complete graphene blocks, which makes it difficult for some devices to flatten and transport the graphene powders on a flattening rack, which makes it inconvenient for the moisture inside the graphene raw materials to volatilize quickly. Finally, some devices find it difficult to adjust the flattening thickness according to the water content of the graphene raw materials, which makes it difficult to fully dry some graphene powders, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a graphene drying device is proposed. Summary of the invention
