Quartz powder treatment device for electronic packaging

Abstract

The invention discloses a quartz powder treatment device for electronic packaging. The device comprises a grinding unit and a recovery unit, wherein quartz powder and deionized water enter a feeding port to be ground, enter a first guide part from a discharging port through filter screen gaps of layering assemblies after being fully ground, and flow into a recovery part through the first guide part; and large-particle quartz powder is brought to a high position by the recovery part and is guided into the feeding port through a second guide part. According to the device, through cooperation offirst filter parts and second filter parts, the filter screen gaps of the layering assemblies can be adjusted, and the grinding precision of the quartz powder can be adjusted as required; through therecovery part, the large-particle quartz powder flowing out of a roller along with water flow can be conveyed back into the roller to continue to be ground, so that the screening effect is achieved; and then the quartz powder is further ground through the side face of a spiral blade and the inner side face of a cylinder, so that the secondary grinding effect is achieved.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a quartz powder processing device for electronic packaging. Background technique [0002] Quartz powder (same as quartz sand) is also called silica powder. Quartz sand is a hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is silicon dioxide. The color of quartz sand is milky white, or colorless and translucent, with a Mohs hardness of 7. Cleavage, shell-like fracture, grease luster, its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750 ℃. After the quartz stone mined from the mine is processed, the product with a fineness below 120 mesh (less than 120 mesh) is called quartz sand, and the product with a fineness of more than 120 mesh is called quartz powder. [0003] The existing ground quartz powder is discharged from the outlet of the quartz powde...

AI Technical Summary

Problems solved by technology

[0003] The existing ground quartz powder is discharged from the discharge port of the quartz powder processing device for electronic packaging, and there may be problems that the grinding of the quartz powder is insufficient and the fineness of the grinding cannot be adjusted.
