Continuous production equipment for silicon monoxide

Abstract

The invention discloses continuous production equipment for silicon monoxide. The continuous production equipment comprises a furnace, a vacuum screw feeding device and a screw receiving device, wherein the furnace inside is a preparation area of silicon monoxide and comprises a reaction area and a diffusion area; the vacuum screw feeding device is mounted at the upper part of the furnace, and thelower end part of the vacuum screw feeding device is connected with the reaction area of silicon monoxide; the screw receiving device is connected with the furnace in a through manner and connected with the diffusion area, and the lower end part of the screw receiving device is connected with a receiving tube; the furnace is further connected with a vacuum pump; a bracket is further fixedly mounted at the bottom end part of the furnace. By means of the vacuum screw feeding device and the screw receiving device, problems about continuous feeding and discharging of silicon monoxide at high temperature and under high vacuum are solved, the continuous production equipment has the characteristics of being simple in design and convenient to clean and maintain, further, the mechanization level and automation level of the equipment are high, energy can be saved effectively, energy utilizing efficiency can be increased, and production efficiency of silicon monoxide can be increased greatly.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to an equipment device for continuous production of silicon monoxide. Background technique [0002] With the rapid development of new energy vehicles, the performance of lithium-ion batteries needs to be further improved, thus putting forward higher requirements for lithium-ion battery materials, among which silicon monoxide materials have always been the focus of research. Although the silicon monoxide material has good electrochemical properties, the preparation method of silicon monoxide is too harsh and requires high equipment requirements. It is necessary to mix the raw materials silicon and silicon dioxide at a high temperature of 1200°C-1400°C and 10 -2 -10 -3 Under the condition of Pa vacuum, it is first converted into silicon monoxide vapor, then condensed, and finally the silicon monoxide material is prepared. It is precisely because of the temperature and vacuum require...
