Description

Technical Field

[0001] This utility model relates to the technical field of graphene-related equipment, specifically a graphene conductive slurry homogenization treatment device. Background Technology

[0002] Graphite, by its very nature, possesses a layered structure that can be exfoliated, allowing graphene to be obtained by peeling off its layers. To achieve rapid graphene exfoliation, an oxidizing agent is typically used to deeply oxidize the flake graphite, followed by easy peeling of the graphite layers using ultrasonic equipment, and finally, chemical reduction is applied to produce graphene. However, this method results in graphene with numerous structural defects due to the intense oxidation process, leading to a significant decrease in graphene performance. Furthermore, even after reduction, the defects in the graphite's layered structure cannot be repaired. More seriously, the production process requires large amounts of sulfuric acid as an oxidizing agent, causing environmental pollution. Physical mechanical shearing exfoliation can achieve large-scale, low-cost, and environmentally friendly graphene production. For example, graphene exfoliation can be achieved through mechanical impact using ball mills, colloid mills, etc. In practice, while repeated mechanical grinding yields graphene, the grinding stress and impact damage the graphite lattice, and due to the graphene size effect, nanoscale graphene is highly prone to aggregation. Existing research has shown that liquid-phase exfoliation can prevent graphene from being subjected to pressure shocks while simultaneously achieving graphene dispersion. The resulting graphene slurry has been widely used in fields such as anti-corrosion coatings and battery slurries.

[0003] In a Chinese patent with publication number CN206296037U entitled "A Homogenizing Shearing Machine for Industrial Preparation of Graphene Materials", the fan-shaped blades on the main shaft generate high-speed turbulence in the vertical and centrifugal directions of the slurry. Under the action of high-speed impact tearing and turbulence, the slurry collides and breaks with the grinding teeth on the inner wall of the reactor, which greatly improves the peeling efficiency.

[0004] However, this device still has shortcomings. After the vessel is used, due to the special physical and chemical properties of graphene conductive slurry, it is easy for it to adhere and settle on the inner wall and bottom of the vessel. Furthermore, there is no corresponding structure for cleaning the inside of the vessel, which makes cleaning inconvenient. In order to solve the above problems, the inventors have proposed a graphene conductive slurry homogenization treatment device. Utility Model Content
