A tower type microwave graphite expansion equipment

Abstract

The invention discloses tower-type graphite expanding microwave equipment. Through adoption of a tower-type structure, by virtue of a feeding device on a tower body and the gravity, a graphite material is uniformly sent to a heating chamber for microwave heating expansion, so that a phenomenon of incomplete partial expansion due to nonuniform spreading of the graphite material can be reduced and the yield is increased; compared with the conventional expanding way, an expanding way provided by the invention has the advantages as follows: the tower-type graphite expanding microwave equipment issimple in structure and low in cost, the expanding way is easy to implement, and by the expanding way, the graphite expanding production efficiency can be greatly improved. The tower-type graphite expanding microwave equipment, comprises an overall equipment framework, the tower body, a cooling device and a control console, wherein the tower body is mounted inside the overall equipment framework;a smoke exhausting device, a heating chamber, a cooling buffer bin and a discharging device are sequentially arranged on the tower body from top to bottom; a feeding device is arranged beside the smoke exhausting device.

Description

technical field [0001] The invention relates to the technical field of graphite expansion equipment, in particular to a tower-type microwave graphite expansion equipment. Background technique [0002] Expanded graphite is a product obtained by expanding expandable graphite. It has excellent physical and chemical properties and is widely used in the fields of sealing, flame retardant, lubrication, environmental protection, military and catalysis. The traditional puffing method is to puff it in a muffle furnace at 800°C to 1000°C. However, this puffing method takes a long time to heat and consumes a lot of electric energy during the puffing process. In order to overcome the defects of the traditional high-temperature expansion method, some new expansion methods, such as laser, infrared, microwave, and electric current, have been applied in the expansion of expandable graphite. [0003] Microwave is a kind of electromagnetic wave with extremely short wavelength. It belongs to ...

AI Technical Summary

Problems solved by technology

Due to the good electrical conductivity of expanded graphite, in the preparation of expanded graphite by microwave method, the conductivity of expanded graphite forms a certain shielding of microwaves, which leads to partial inhomogeneity of expanded graphite prepared by microwave method, especially in the process of industrial production. The uneven thickness of graphite paving is more likely to cause incomplete local expansion.
