Problems solved by technology
[0003] At present, the existing equipment for preparing graphene adopts the material of graphite rods, but the shortcoming is that the graphite rods are short. During the production process, the reaction of the graphite rods decreases accordingly. As the graphite rods gradually shrink during the production process, there will be Current fluctuations and voltage fluctuations make the quality of the produced graphene products unstable and the output is low. The equipment for producing graphene uses argon and hydrogen as protective gases and reacts with high pressure, which is dangerous and not only high in production costs , and the production efficiency is low

An equipment for preparing graphene by arc method, the equipment is composed of hydrogen, helium cylinder, anode, cathode, thruster, cavity, display screen, refrigeration device, discharge equipment, workbench, etc. The workbench is equipped with a chamber There are multiple interlayers in the cavity, a discharge port at the bottom, an anode on the left, a propeller on the right, a cathode at the bottom of the cavity, and a display in the middle of the workbench. The propulsion device is working At the end of the table, there is a discharge device inside the workbench, a distribution box, and a refrigeration device outside. The feature is that the vacuum chamber is equipped with multiple interlayers, hydrogen and helium are used as protective gases, and the extended high-purity graphite rod is used as the cathode and The anode generates an arc under the discharge conditions of the discharge equipment, which consumes the extended high-purity graphite rod. The discharge equipment adjusts the voltage and current to increase the efficiency of production. The operation is simple, the safety is increased, the cost is reduced, the reaction conditions are stable, and the production The graphene is of good quality and is an ideal equipment for producing graphene.
Description
[0001] Technical field [0002] The invention relates to equipment for preparing graphene by arc method, which is a kind of equipment for producing graphene. Background technique [0003] At present, the existing equipment for preparing graphene adopts the material of graphite rods, but the shortcoming is that the graphite rods are short. During the production process, the reaction of the graphite rods decreases accordingly. As the graphite rods gradually shrink during the production process, there will be Current fluctuations and voltage fluctuations make the quality of the produced graphene products unstable and the output is low. The equipment for producing graphene uses argon and hydrogen as protective gases and reacts with high pressure, which is dangerous and not only high in production costs , and the production efficiency is low. Contents of the invention [0004] In order to overcome the above existing problems, the object of the present invention is to provide a k...
