Abstract

The invention relates to a liquid crystal glass raw material feeding method which aims at improving the uniformity and stability of the liquid crystal glass raw material; a steel grid device is additionally arranged at a feed port of a material bin to remove the iron of the batch material; an electronic scale is arranged below the material bin; the raw material is discharged into a material collecting hopper through a flashboard below the electronic scale; the flashboard is connected with the material collecting hopper through a wearable pipe; the material collecting hopper is connected with a mixer; a vibration hitting device is arranged at the lower part of the material collecting hopper; the interior of the mixer adopts highly wear-resistant material; the raw material with small consumption is added into a material bin with larger consumption; the mixer is communicated with a storage tank through a flashboard at the lower part; upon good combination, the mixture is hoisted in a using material bin; the method enables a minimum amount of impurities introduced during the delivery of raw materials; the batch material of the raw material can achieve best uniformity, so the method isespecially suitable for liquid crystal glass production with higher requirements on raw materials.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal glass production, and relates to a liquid crystal glass raw material delivery method aimed at improving the uniformity and stability of the liquid crystal glass raw material, which can minimize the amount of impurities introduced into the raw material during transportation and improve the uniformity of raw material batching To achieve the best, especially suitable for the production of liquid crystal glass with high requirements on raw materials. Background technique [0002] In the production technology of liquid crystal glass, the uniformity and stability of raw materials is a very important technical index, and the requirements for iron content are also very strict. If the raw materials cannot meet the technical index requirements, the quality of the glass will not be guaranteed at all. Because the liquid crystal glass substrate is very thin, the requirements for glass melting quality an...

AI Technical Summary

Problems solved by technology

[0005] First of all, belt conveyors, vibrating feeders, bucket elevators, baffles, mixers and other equipment are prone to wear and tear, and impurities enter the batch. However, the production process of liquid crystal glass has strict requirements on impurities, especially iron liquid crystal glass. 500PPM, once the index is exceeded, the liquid crystal glass substrate product will be discarded

[0006] Secondly, the use of belts will cause the adhesion of raw materials and the volatilization of powder materials, especially the raw materials used in a small amount in the raw materials. If they adhere or volatilize, the composition of the batch materials will fluctuate, resulting in glass components. glass production accident

[0007] Thirdly, liquid crystal glass also has strict requirements on moisture content, and the moisture content should be controlled at about 0.2%. However, the use of traditional transmission methods will cause fluctuations in the moisture content of batch materials, which will affect the melting process and cause fluctuations in production

[0008] In addition, liquid crystal glass requires a uniformity of more than 97.5%. Using traditional transportation methods, the raw materials are first discharged onto the conveyor belt, then mixed with a mixer, and then the material is discharged into the silo through the conveyor belt. Uniformity will not meet the requirements of liquid crystal glass production process, and uneven batching will lead to instability of raw material melting, clarification and homogenization of glass liquid, resulting in fluctuations in production process and affecting the yield of glass

[0009] Therefore, the traditional method of transporting raw materials cannot meet the production process requirements of liquid crystal glass ingredients in terms of accuracy, uniformity, iron content, moisture, and purity, and cannot guarantee the yield of glass products produced
