Graphene drying equipment and drying method thereof

Abstract

The invention relates to the technical field of drying treatment, and discloses graphene drying equipment and a drying method thereof. The graphene drying equipment comprises a shell, the upper top ofthe shell is connected with a motor in a penetrating mode, the lower end of the motor is fixedly connected with an output shaft, the output shaft extends into the shell, the other end of the output shaft is sleeved with a threaded rod, a storage barrel is slidably connected to the threaded rod, an electrode plate is fixedly connected to the upper end of the interior of the shell in the horizontaldirection, and a second partition plate is fixedly connected to the lower end of the electrode plate. A drying chamber is heated by electrifying a tungsten filament, meanwhile, electron cloud is generated around the high-temperature tungsten filament, graphene belt electrons are adsorbed on a positive plate, and meanwhile, through cooperative arrangement of the threaded rod, a sliding block and the high-voltage electrode plate, the effect of fully evaporating residual water molecules of graphene powder atoms is achieved, and the problem that in the prior art, water molecules remain in graphene powder, and consequently a large amount of graphene powder is aggregated into blocks is solved.

Description

technical field [0001] The invention relates to the technical field of drying treatment, in particular to a graphene drying equipment and a drying method thereof. Background technique [0002] Graphene is known as the greatest material in the 21st century. Its physical and chemical properties are the mainstream of future material technology development. Its scientific strategic significance is very important. It has triggered a material revolution on a global scale. The preparation method of graphene is as follows: mechanical Among these preparation methods, the redox method has the lowest cost and the most ideal preparation results, and is widely used. The specific method is as follows: oxidizing natural graphite with a strong oxidant to obtain graphene oxide, reacting graphene oxide and its aqueous solution with a reducing agent, fully reacting, filtering, and drying to obtain graphene. In this process flow, the drying of graphene is especially critical. [0003] Most of...
