Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: the oxidation furnace in the existing equipment for preparing graphene composite materials does not have the function of automatic rotation, so that the raw materials in the oxidation furnace are not heated evenly and uneven mixing affect the quality of the prepared graphene
In addition, it is difficult for existing oxidation furnaces to simultaneously achieve such a high temperature and such a large volume in the presence of air.

Embodiment Construction

[0022] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", and "bottom" used in this specification is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the The invention and the simplified description do not indicate or imply that the device or element referred to must have a specific orientation...

Abstract

The invention relates to the technical field of chemical equipment, and provides an oxidizing furnace. The oxidizing furnace comprises an oxidizing furnace body and a bearing assembly. The oxidizing furnace body is installed on the bearing assembly. The oxidizing furnace body comprises an outer shell, an inner shell and a heating pipe. The outer shell is provided with a containing cavity, and the outer shell and the bearing assembly are fixedly connected; the inner shell is located inside the containing cavity, and the inner shell can rotate relative to the outer shell; the heating pipe is located inside the containing cavity, and the heating pipe surrounds the outer side face of the inner shell. In this way, in the material machining process of the oxidizing furnace, on one hand, it can be ensured that raw materials inside the inner shell are heated to be uniform; on the other hand, the certain stirring effect can be achieved, and therefore the raw materials can be subjected to a complete oxidizing reaction inside the oxidizing furnace.

Description

【Technical field】 [0001] The invention relates to the technical field of chemical industry, in particular to an oxidation furnace. 【Background technique】 [0002] As a new two-dimensional honeycomb carbonaceous material, graphene has the characteristics of outstanding mechanical properties (1060GPa), large specific surface area (2600m~2 / g), and excellent electrical conductivity. It has been successfully applied in nanoelectronic devices, photonic sensors and Gene sequencing and other fields. The excellent energy storage properties of graphene are currently an important research direction. Compared with commercial graphite electrodes, graphene has nearly three times the theoretical energy storage capacity, which provides a new idea for coping with the growing energy demand. However, it is difficult for graphene to be used as a single raw material to produce a certain product. It is mainly to use its outstanding characteristics to combine with other material systems to obtain...
