A kind of expansion equipment for graphene preparation

Abstract

The invention discloses a puffing device for preparing graphene, and solves the problems that a large amount of heat is easily lost and the stirring efficiency of a stirring shaft is not high due to the fact that a cabin door is opened in an existing furnace body heating process. The device comprises a hollow furnace body, a rotatable sun gear is arranged in the furnace body, the outer side of thesun gear is meshed with a plurality of planet gears, an inner gear ring is fixedly connected in the furnace body, and the plurality of planet gears are meshed with the inner gear ring; a planet shaftis fixedly connected to the lower end of each planet gear, a hexagonal prism is fixedly connected to the lower end of each planet shaft, and a stirring part is connected to the outer circumference ofeach hexagonal prism and is of a vertical lifting structure; stirring blades are fixedly connected to the lower end of each hexagonal prism; a box body capable of sliding horizontally is arranged inthe furnace body, a plurality of through holes are formed in the lower end of the box body, and a control part for controlling the through holes to be closed is arranged at the lower end of the box body; the upper end of a sun shaft penetrates through the furnace body and is arranged above the furnace body, a driving unit for controlling the sun shaft to rotate forwards and backwards is arranged above the furnace body, and the driving unit is fixedly connected with the sun shaft.

Description

technical field [0001] The invention relates to the technical field of graphene preparation, in particular to an expansion device for graphene preparation. Background technique [0002] The carbon atoms in graphene are arranged in the same way as the single atomic layer of graphite in SP 2 Hybrid orbitals form bonds and have the following characteristics: carbon atoms have 4 valence electrons, of which 3 electrons generate SP 2 Bond, that is, each carbon atom contributes an unbonded electron located in the PZ orbital, and the PZ orbital of the adjacent atom is perpendicular to the plane to form a π bond, and the newly formed π bond is in a half-filled state. Studies have confirmed that graphene has excellent electrical and optical properties. [0003] Because graphene has these characteristics, it is suitable for the manufacture of transparent touch screens, light panels, and even solar cells and other fields, making the preparation and application of graphene gain unprece...
