Embodiment Construction

[0009] The present invention will be further described below in conjunction with specific embodiment:

[0010] refer to figure 1 , in this embodiment, the small-sized graphite expansion device includes a U-shaped pipeline 1, a hopper 2, a heating source 3, a discharge port 4, a thermometer 5 and a collection tank 6 for dead graphite insects, and the outlet on one side of the U-shaped pipeline extends Inside the inlet and outlet 4, the other side of the U-shaped pipe 1 is provided with a feed hopper 2, a thermometer 5 and a heating fire source 3 in sequence, and a graphite dead insect collection tank 6 is disposed at the outlet of the lower end. A valve is provided on the pipeline connecting the feed hopper 2 and the U-shaped pipeline 1. After the valve is opened, the expanded graphite enters the pipeline 1 to be heated. What the heating fire source 3 sprays is acetylene gas or a combustion body of natural gas and oxygen, which is used to heat the graphite to be expanded. The...

Abstract

The invention relates to a small graphite expansion preparation method and device. The device comprises a U-shaped pipeline, a feeding hopper, a heating fire source, a discharging port, a thermometerand a graphite dead insect collecting tank. An outlet in one side of the U-shaped pipeline extends into the discharging port, the feeding hopper, the thermometer and the heating fire source are sequentially arranged on a pipeline on the other side of the U-shaped pipeline, and the graphite dead insect collecting tank is arranged at an outlet in the lower end of the U-shaped pipeline. A valve is arranged on a pipeline for communicating the feeding hopper with the U-shaped pipeline. The device is ingenious in design and simple in structure, expanded graphite can be prepared on a large scale, high efficiency is achieved, and cost can be saved.

Description

technical field [0001] The invention belongs to the technical field of graphite preparation, in particular to a method and device for preparing small-scale expanded graphite. Background technique [0002] In the prior art, natural flake expanded graphite is a common raw material for preparing graphene. At present, there is an urgent need for a simple and feasible method and device that can prepare expanded graphite in large quantities to quickly prepare expanded graphite. Contents of the invention [0003] The purpose of the present invention is to solve the problem that a large amount of expanded graphene cannot be easily and quickly obtained in the existing graphite preparation, and further provide a small graphite expansion device. [0004] The technical scheme of the present invention is: a small-sized graphite expansion device, comprising a U-shaped pipeline 1, a feed hopper 2, a heating fire source 3, a discharge port 4, a thermometer 5 and a graphite dead insect col...
