Description

Technical Field

[0001] The utility model relates to the field of graphite processing, in particular to a dust reduction and drying device for graphite processing. Background Art

[0002] Graphite has the properties of high temperature resistance and high strength. It is used as a refractory material and conductive material in many fields such as military industry, aerospace, aviation, and automotive grease sealing materials. During the processing and production of graphite, it needs to be dried before further processing. Therefore, before the deep processing of graphite, it needs to be dried. Graphite is divided into graphite powder and graphite blocks, which need to be dried;

[0003] However, when the existing graphite drying device is used, the moisture contained in the graphite block before drying will cause water vapor to be generated inside the drying barrel. However, in order to prevent the graphite dust from leaking out and polluting the environment, the drying barrel is usually equipped with a sealing device and a dust removal device, and the drying barrel is mostly arranged horizontally. Due to its shape, the water vapor cannot be discharged well, so that the humidity inside the drying barrel is relatively high due to the water vapor, which affects the drying speed and causes a long production process time.

[0004] Therefore, it is necessary to propose a dust reduction and drying device for graphite processing to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a dust reduction and drying device for graphite processing, so as to solve the problem that water vapor cannot be discharged well due to the sealing of the drying barrel and the horizontal placement of the drying barrel during graphite drying, resulting in a long production process.
