Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass raw material processing, and particularly relates to a raw material processing device with screening and mixing functions. BACKGROUND

[0002] Display special glass processing is a systematic process from raw materials to finished products, covering raw material processing, high-temperature melting, shaping and sizing, heat treatment and post-processing, etc. Each step directly affects the product quality, and for the raw material processing link, display special glass is processed from multiple raw materials. When multiple raw materials are processed, they need to go through steps such as screening and mixing.

[0003] When mixing multiple raw materials required for the preparation of the existing display special glass, the multiple raw materials are usually poured into a mixing cylinder for stirring and mixing. This process has the following disadvantages. For the case of pouring different raw materials from the same feeding port in sequence, the different raw materials will be layered and stacked in the mixing cylinder. The subsequent stirring can hardly mix the raw materials at the top and the bottom. For the case of adding different raw materials from different feeding ports at the same time, multiple raw materials can fall into the mixing cylinder at the same time, avoiding the layered stacking of multiple raw materials. Since the different raw materials fall into the mixing cylinder from different feeding ports at different positions, the mixing effect will be improved by subsequent stirring with a stirring rod. However, the mixing effect is still limited by mixing the raw materials in the mixing cylinder only with the stirring rod. Moreover, the existing raw material processing device needs to be screened separately. After screening, the raw materials with unqualified sizes are taken out for crushing, and then the raw materials with qualified sizes are mixed again. The steps are more and the operation is complicated, which affects the processing efficiency. SUMMARY

[0004] The present application aims to solve the problems of the prior art and provide a raw material processing device capable of mixing raw materials during raw material conveying, screening raw materials, and crushing raw materials with unqualified sizes.
