Equipment and method for preparing high-purity magnesium silicide powder

Abstract

The invention belongs to the field of magnesium silicide powder preparation, and particularly relates to high-purity magnesium silicide powder preparation equipment and method.The high-purity magnesium silicide powder preparation equipment comprises a device shell, a servo motor is welded and fixed to the device shell, a connecting plate is welded and fixed to an output shaft of the servo motor, and the other end of the connecting plate is rotationally connected with a fixing shaft; a first circular gear and a grinding wheel are welded and fixed to the fixing shaft, an inner gear is connected to the first circular gear in a meshed mode, the inner gear and the grinding frame are welded and fixed in the device shell, a protection plate is rotationally connected to the fixing shaft, and the protection plate is rotationally connected to the grinding frame through a sealing bearing. The problems that an existing magnesium silicide preparation method needs to use various devices, the preparation efficiency is low, the preparation cost is high, a conventional preparation device cannot conduct integrated preparation work such as mixing and grinding on magnesium silicide powder at the same time in the working process, and then the preparation efficiency cannot be effectively improved are solved.

Description

technical field [0001] The invention relates to the field of magnesium silicide powder preparation, in particular to equipment and a method for preparing high-purity magnesium silicide powder. Background technique [0002] As an essential special gas for the production of polysilicon and energy-saving glass, silane is widely used in the fields of electronic products, high-efficiency solar cells, aerospace and military industries. At present, the method of producing silane in the world is mainly Japan's Komatsu Electronics method (magnesium silicide method) , the magnesium silicide method has the advantages of low investment, mature technology, and low energy consumption, and is used as an important raw material for the production of silane by the magnesium silicide method; [0003] In the preparation process of magnesium silicide, it is necessary to use mixing equipment to uniformly mix silicon powder and magnesium powder, and then the mixed raw materials need to be transpor...

AI Technical Summary

Problems solved by technology

[0003] In the preparation process of magnesium silicide, it is necessary to use mixing equipment to uniformly mix silicon powder and magnesium powder, and then the mixed raw materials need to be transported to the grinding equipment for grinding treatment, and finally the ground raw materials are transported to the heat treatment equipment In summary, the conventional preparation method of magnesium silicide needs to use a variety of equipment, the preparation efficiency is low and the preparation cost is high, and the conventional preparation equipment cannot simultaneously mix and mix the magnesium silicide powder during the working process. Grinding and other integrated preparation work can not effectively improve the preparation efficiency, so it is necessary to provide a high-purity magnesium silicide powder preparation equipment and method to meet the needs of users
