Description

Technical Field

[0001] The utility model relates to the technical field of graphene processing, in particular to a graphite oxidation device for graphene production. Background Art

[0002] Graphene has extremely high electron mobility and high conductivity, and therefore has important applications in electronic devices, sensors, and conductive materials. The production process of graphene often involves a graphite oxidation device. After the graphite material is oxidized, a filtering structure is required to separate the solid material from the solution.

[0003] A Chinese patent discloses an energy-saving and environmentally friendly graphene oxidation tank (authorization announcement number CN212101998U). The patented technology includes an outer oxidation tank body, an inner oxidation tank body is arranged on the inner side of the outer oxidation tank body, an electric heating plate is arranged between the outer oxidation tank body and the inner oxidation tank body, an exhaust groove is arranged on the inner side wall of the inner oxidation tank body, a bottom exhaust groove is arranged at the bottom end of the inner oxidation tank body, a stirring motor is arranged at the top of the outer oxidation tank body, and the bottom end of the stirring motor is rotatably connected to a stirring shaft through a rotating shaft, and the stirring shaft runs through the central axis position of the inner oxidation tank body. The utility model accelerates the flow rate of the liquid inside the inner stirring cover and reduces the hydraulic pressure. The liquid outside the inner stirring cover flows into the inner stirring cover through a circular leakage groove to form a circulation, thereby avoiding the problem that when using the graphene oxidation tank, the graphene oxidation tank is difficult to make the liquid in the inner oxidation tank body fully roll up and down and stir, thereby affecting the use effect of the graphene oxidation tank.

[0004] This patented technology, when in use, the material is rolled up and down in the oxidation tank to mix evenly, but there is still insufficient support during use. The solid matter needs to be separated after oxidation processing. This process requires filtering the oxidized graphite material. The filtering process increases the process of transportation and filtration, which reduces the processing efficiency of graphite oxidation. Therefore, those skilled in the art provide a graphite oxidation device for graphene production to solve the problems raised in the above background technology. Utility Model Content
