[0002] Graphene, as a two-dimensional carbon nanomaterial with outstanding properties, has shown great application potential in many fields. However, the preparation of graphene dispersions faces numerous technical challenges.
[0003] Currently, traditional emulsification devices for preparing graphene dispersions rely solely on a single emulsifier for stirring. The stirring intensity and range are limited, making it difficult to disperse graphene quickly and uniformly in the dispersion medium. This results in insufficient mixing of graphene powder and the dispersion medium, causing a large number of graphene particles to easily agglomerate together, making efficient emulsification impossible. Consequently, the preparation process is time-consuming and production efficiency is low.
[0004] Therefore, in order to solve the above problems, it is necessary to design a circulating emulsification device for the preparation of graphene dispersion. Utility Model Content

The three-way valve is opened, and the pump and emulsifier are started. The pump pumps the material at the bottom of the mixing tank into the emulsification cylinder.

The material in the mixing tank 101 is conveyed to the emulsifying cylinder 401 for emulsification, and then conveyed back to the mixing tank 101 for multiple cycles of mixing and emulsification. The third port of the three-way valve 2 is used as a discharge port to discharge the material from the mixing tank 101. The three-way valve 2 is preferably an electric three-way valve, which can be remotely or automatically controlled. The pump 3 is preferably a circulating pump. The bottom of the emulsifying cylinder 401 is connected to the outlet pipe of the pump 3, so that when the pump 3 conveys the material, the liquid level in the emulsifying cylinder 401 rises from bottom to top, so that the emulsifier 4 can fully emulsify the material and enhance the emulsification effect.
[0021] In this embodiment, graphene powder and dispersion medium are added to the mixing tank 101. The stirring assembly 102 is started to initially stir the materials, so that the graphene powder and dispersion medium are initially mixed, reducing large-scale agglomeration.
