Purification device for production of electronic-grade silica powder and implementation method of purification device

Abstract

The invention discloses a purification device for electronic-grade silica powder production and an implementation method of the purification device, belongs to the technical field of silica powder purification, and aims to solve the problems that particles cannot be classified and screened when existing silica powder is purified and screened, so that the particles are easy to block a screen, and the screening efficiency of the particles is influenced. Secondly, the existing silica powder is subjected to impurity adsorption through a roller magnet, and the adsorption surface of the roller magnet is too small, so that the impurity removal efficiency is poor. Through effective removal of particles in silica powder and up-down back-and-forth telescoping, mesh blockage can be effectively prevented, through arrangement of three-stage screening, impurity separation is effectively carried out while the screening efficiency is improved, and a screening cylinder drives a screening rod to retract, so that a screen is inclined, impurities left after filtration are effectively cleaned, next powder screening is facilitated, and the screening efficiency is improved. And the motor drives the conveying rollers to rotate for conveying, so that impurities in the filtered silica powder can be effectively sucked away, and the purification efficiency of the silica powder is ensured.

Description

technical field [0001] The invention relates to the technical field of silicon micropowder purification, in particular to a purification device for the production of electronic grade silicon micropowder and an implementation method thereof. Background technique [0002] Electronic-grade silicon micropowder is made of high-quality natural quartz as raw material and processed by a special process. It has the characteristics of high silicon dioxide content, low ion content, and low electrical conductivity. It is an ideal filler for electronic and electrical plastic packaging materials, molding compounds and high-performance electronic components. It is used as an electronic packaging material for LED, SMD, EMC electronic separation devices, and electrical products. Its main functions are waterproof, dustproof, and harmful gas. Slow down vibration, prevent external force damage and stabilize circuit. Electronic-grade ultra-fine high-purity quartz powder is the main raw material...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing microsilica powder cannot classify and sieve the particles when purifying the sieve material, which causes the particles to easily block the sieve and also affects its sieve efficiency;

[0004] 2. Secondly, the existing silicon micropowder uses roller magnets to adsorb impurities, and the adsorption surface of the roller magnets is too small, resulting in poor removal efficiency of impurities
