Quartz sand feeding device and method

Abstract

The invention relates to a quartz sand feeding device and method. The quartz sand feeding device comprises a cover plate, an observation window and a bottom plate, wherein the observation window has ahollow structure; the cover plate, the observation window and the bottom plate are successively connected to form a closed cavity; the inside of the cavity is rotatably connected with a rotating plate; the bottom plate is connected with a driving source which drives the rotating plate to rotate; the bottom plate is connected with a discharging connector which communicates with the cavity and is provided with a discharging channel; a feeding opening of the discharging connector is positioned between the inner wall of the observation window and the side wall of the rotating plate; a feeding adjusting tube with a feeding channel is arranged on the cover plate; a feeding opening of the feeding adjusting tube is positioned on the upper part of the rotating plate; a scraper blade is arranged onan end surface, which faces the rotating plate, of the cover plate; the lower end surface of the scraper blade is attached to the upper end surface of the rotating plate; and the discharging direction of the scraper blade corresponds to the feeding opening of the discharging connector. The quartz sand feeding device has the advantages that the quartz sand feeding amount is controlled, the quartzsand feeding accuracy is improved, and the follow-up quartz sand processing procedures are ensured.

Description

technical field [0001] The invention relates to the field of processing quartz glass products, in particular to a quartz sand discharging device and a sand discharging method. Background technique [0002] Quartz glass is a special glass containing only silicon dioxide. Due to different types, processes, and raw materials, it is often called silicate glass, quartz glass, fused quartz, fused quartz, synthetic fused quartz, and transparent, translucent, and opaque quartz without a clear concept. my country is collectively referred to as quartz glass, which is mostly classified according to process methods, uses and appearance, such as fused transparent quartz glass, continuous fused quartz glass, gas-refined transparent quartz glass, synthetic quartz glass, opaque quartz glass, optical quartz glass, and quartz glass for semiconductors , Quartz glass for electric light source, etc. [0003] Due to the excellent properties of quartz glass, it is widely used in the manufacture o...

Problems solved by technology

However, during the processing of existing quartz glass products, the quartz sand needs to be pretreated for subsequent processing, while the existing quartz sand is in the blanking process, and the quartz sand on the blanking plate is cleaned by vibrating screens. Vibration realizes blanking, and the blanking device of this structure cannot control the quantity of quartz sand blanking, resulting in poor accuracy of quartz sand blanking, which affects subsequent processing
