Industrial large-scale reaction vessel for preparing graphene

Abstract

The invention relates to an industrial large-scale reaction vessel for preparing grapheme. The reaction vessel comprises a shaft sealing apparatus, a transmission apparatus, a protection supporting framework (2), a gas collecting bottle (8), a frequency-conversion speed-regulation stirrer (6) and a temperature measurement tube (7). The protection supporting framework (2) is provided with a reaction bottle (1), wherein the reaction bottle (1) is connected with a thermostatic bath (3) on outside thereof, and is provided with charging ports (4) and an exhaust emission port (5) at the upper part thereof and a discharging port (13) at the lower part thereof. The reaction bottle can automatically control reaction temperature, stirring speed and constant-temperature state during a whole process of preparation of oxide grapheme. Pollution of different raw materials can be prevented by using a plurality of charging ports. The reaction vessel has advantages of wide range of constant temperature, large volume and compact structure, and is suitable for physical and chemical reactions in large doses.

Description

Technical field [0001] The invention relates to a container for physical or chemical reactions, in particular to an industrial reactor for preparing graphene oxide. Background technique [0002] At present, the material of the reactor is generally carbon-manganese steel, stainless steel, zirconium, nickel-based alloy and other composite materials. The rotating mechanism of the agitator is a cycloidal pinwheel reducer, a stepless speed reducer, etc., and the volume of the reactor is relatively small. The lowest constant temperature range can only be above zero. Contents of the invention [0003] In order to solve the problems of poor corrosivity of existing materials, difficulty in controlling the stirring speed, and small volume of the reaction kettle, the present invention provides a large-scale reaction kettle for preparing graphene for industrial use, which can be used under strong corrosion conditions, and has no impact on the whole process. Carry out automatic contro...
