High-efficiency drying equipment for graphene production and drying method

Abstract

The invention discloses high-efficiency drying equipment for graphene production and a drying method in the technical field of graphene production. The high-efficiency drying equipment comprises a drying box, wherein feeding plates, positioning plates and a material guide plate are sequentially arranged in an inner cavity of the drying box from top to bottom; a plurality of material placing mechanisms are evenly arranged between the material guide plate and the positioning plates; a driving assembly is connected to the bottom of each material placing mechanism; and a drying assembly is arranged on the material guide plate. According to the high-efficiency drying equipment and the drying method, materials are drained through draining barrels, the draining speed is increased through the centrifugal effect during rotation, and drained water cannot be thrown into the adjacent draining barrels through the effect of annular baffles; and under the action of a first electromagnet and adsorption plates in connecting cylinders, water retaining cylinders move downwards, dewatering tanks and the concave positions of the draining barrels are staggered, then drying is carried out through the drying assembly, after drying is finished, the draining barrels move upwards, the bottom ends of the draining barrels are separated from sealing tables, and the materials move outwards along the top surfaces of the sealing tables and fall onto the material guide plate.

Description

Technical field [0001] The present invention relates to the technical field of graphene production, and is specifically used for high-efficiency drying equipment and drying methods for graphene production. Background technique [0002] Graphene is a SP by carbon atom 2 Hybrid tracks form a two-dimensional carbon nanoma with a hexagonal lattice. [0003] Grainne is one of the most known intensity, but also has a good toughness, and can be bent, the theoretical Young's modulus of graphene reaches 1.0 TPa, and inherent tensile strength is 130 gpa. Reduction graphene modified by hydrogen plasma has a very good strength, and the average modulus can be 0.25TPa. [0004] The graphite paper composed of graphene flakes has a lot of holes, so the graphite paper is very brittle, however, the oxidation of functionalized graphene is obtained, and the functionalized graphene is made into a graphite paper will be very strong. [0005] Due to high conductivity, high strength, ultra-thin characte...

Problems solved by technology

[0010] In the process of using graphene materials for production and processing, it is usually necessary to dry graphene materials or materials processed from graphene; the existing drying equipment is to put the materials to be dried inside the drying box , drying by hot air. In order to improve the drying effect, the cylinder will be used to place the material, and the draining will be accelerated by rotation, which is convenient for drying. However, the structure for placing the material is usually provided with holes. When the cylinder is rotated to drain, The drained water will fall on the adjacent cylinder, affecting the draining effect and the subsequent drying effect
