Method for drying, screening and collecting graphite powder

Abstract

The invention relates to a method for drying, screening and collecting graphite powder. The method comprises the steps that firstly, the graphite powder is dried through the differential dying technology, then, the graphite powder is screened and collected through airflow classification, and finally graphite products at different levels are obtained. The method for drying, screening and collecting the graphite powder has the advantages that the whole system continuously operates in a sealing mode, energy is saved, consumption is reduced, safety and environmental friendliness are achieved, operation is continuous, the mesh number of the graphite products is increased, and the economic benefits and social benefits of an enterprise are increased. Compared with the prior art, the method for drying, screening and collecting the graphite powder further has the advantages of reducing the labor intensity of workers, reducing contact between the operation workers and the graphite powder, preventing the harm of the graphite powder to the respiratory systems of the workers, greatly improving an operation site, and achieving cleanness and tidiness of the environment of the whole production site.

Description

[0001] technical field [0002] The invention relates to the technical field of energy saving and consumption reduction of graphite powder drying and screening and collection of products. To be precise, a micropowder dryer is used to dry graphite powder to reduce energy consumption per unit of product, and at the same time airflow sieving is used to Product collection, increase product variety and quality. [0003] Background technique [0004] Due to the low price of graphite products for a long time, the graphite industry has not been paid attention to. So far, the production method is rough, the energy consumption is huge, and the on-site environment is harsh. With the development of social economy and the expansion and discovery of the application functions of graphite products, the price of graphite products is soaring. At the same time, the requirements for energy conservation and environmental protection are becoming increasingly stringent. Therefore, a new productio...

AI Technical Summary

Problems solved by technology

[0009] ①In terms of energy consumption: the original graphite powder production process adopts the rotary drum drying method, which is indirect drying, has a small heat transfer coefficient, and at the same time the production method is rough, so the energy consumption is relatively large

[0010] ②Product collection: From the above-mentioned graphite production process, it can be seen that the degree of automation is relatively low, and manual collection is used, so the product yield is low; at the same time, all the collected graphite powder is manually put into the sieving bed for sieving, so the sieving Heavy load, low product quality

[0012] ④In terms of labor intensity: the existing technology is intermittent operation, the operation cycle is long, the labor intensity is high, and the work efficiency is low
