Airflow classification device for high-precision silicon carbide micro powder production and implementation method thereof

Abstract

The invention discloses an airflow classification device for high-precision silicon carbide micro-powder production and an implementation method thereof, relates to the technical field of high-precision silicon carbide micro-powder processing, and aims to solve the problems that fine powder is mixed into coarse powder due to adhesion of fine powder and coarse powder of existing silicon carbide micro-powder, the powder is adhered to the inner wall of a protective shell, and the production cost is low. The technical problems that in the prior art, due to the fact that a grading wheel is in meshed connection with a transmission assembly arranged on the inner side of a protection shell, resources are wasted, the inner wall of the protection shell is not clean, and powder is raised, air pollution is caused, and silicon carbide micro powder is wasted are solved. The middle of the auxiliary dispersing mechanism is in meshed connection with an inner wall cleaning mechanism fixedly arranged at the lower end of the inner side of the protective shell, and a dustproof mechanism is arranged at the lower end of a coarse material discharging opening, so that uniform coarse and fine grading can be achieved, the grading effect is improved, powder cannot be attached to the interior in real time, waste is avoided, and air pollution is reduced; and waste is also avoided.

Description

Technical field [0001] The present invention relates to a high-precision silicon carbide powder processing technology field, particularly to a high-precision silicon carbide powder production of airflow classification apparatus and embodiment thereof. Background [0002] Silicon carbide powder refers to a micron-level silicon carbide powder that uses JZFZ equipment for ultra-fine crushing and grading. Silicon carbide powder is mainly 1200 # and 1500 # mainly, because the silicon carbide powder is mainly used in the abrasive industry, so there are special requirements for the classification of the powder, the powder can not have large particles, so in order to meet the international and domestic product requirements, the general production is the use of JZF grading equipment for high-precision grading. Domestic silicon carbide powder is mainly black silicon carbide powder and green silicon carbide powder. [0003] However, today's silicon carbide powder production with airflow cla...

Problems solved by technology

[0003] However, due to the water vapor in the air, the current airflow classification device for the production of silicon carbide micropowder is easy to stick the fine powder together. The classification effect is poor and the classification accuracy is reduced. During the classification, because the powder is easy to stick to the inner wall of the protective shell, it will not only cause waste of powder, but also cause the inner wall of the protective shell to be untidy. , because there is a gap between the barrel and the discharge port, it is easy to cause the powder to rise, which not only causes air pollution, but also causes waste of silicon carbide powder
