Description

Technical Field

[0001] The invention relates to the technical field of graphene production, and in particular to a mixing and stirring device for graphene production. Background Art

[0002] Graphene is a new material with carbon atoms tightly stacked into a single-layer two-dimensional honeycomb lattice structure. Graphene has excellent optical, electrical and mechanical properties, and 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. When using the redox method to prepare graphene, production equipment with mixing function is usually required to mix the reducing agent and raw materials during the reduction process.

[0003] After searching, in the prior art, the patent application number CN202022856841.6 discloses a graphene production equipment, which relates to the technical field, including two bottom columns, the tops of the two bottom columns are fixedly connected with a support plate, a stirring mechanism is arranged at the bottom of the support plate, and a cooling mechanism is arranged on the right side of the left bottom column. In the utility model, after the material is put in, the external power supply of the AC motor is turned on, the output shaft of the AC motor rotates, driving the rotation of the rotating rod, so that the first stirring rod rotates, so that the material inside the reaction tank is stirred, and the external power supply of the DC motor is turned on at this time. When the positioning pin on the tank cover is inserted into the positioning hole, the abutment plate and the annular sleeve are movably connected, so the rotation of the tank cover drives the rotation of the reaction tank, so that the material inside the reaction tank performs centrifugal motion. Under the action of the second stirring rod and the first stirring rod, while the raw materials react, they are fully stirred so that the reaction is complete, thereby improving the production output of graphene, but the following defects still exist:

[0004] (1) The mixing and stirring equipment for graphene production in the prior art is not convenient for effectively mixing the raw materials at the bottom with the raw materials at the top during the mixing process, and the raw materials are also easily deposited at the bottom of the reaction tank, resulting in poor mixing effect and reduced graphene production efficiency;

[0005] (2) The reaction tank in the mixing and stirring equipment for graphene production in the prior art is located at a high altitude, which makes it inconvenient for operators to add raw materials into the reaction tank, etc., and is inconvenient to use.

[0006] Therefore, we made improvements to this and proposed a mixing and stirring equipment for graphene production. Summary of the invention
