An automatic feeding process and device for an optical glass continuous melting production line

Abstract

The name of the present invention is an automatic feeding process and device for an optical glass continuous melting production line. The invention belongs to the technical field of continuous melting of optical glass. It mainly provides an automatic feeding process and device for continuously drying and dewatering batch materials for melting optical glass, and then continuously feeding them into a glass melting furnace through a ceramic screw propeller. Its main features are: including a feeding and drying device composed of a storage bin, a drying furnace and a mesh belt transmission mechanism, and a ceramic screw feeder; The spiral blade pushes the raw material to the platinum feeding port of the furnace at a constant speed and enters the melting pool. The invention integrates the drying and dewatering link and the missing injection feeding link in the feeding process on the optical glass continuous melting production line to achieve the purpose of automatic feeding, and at the same time reduces the fluctuation of the melting pool temperature and the volatilization of volatile substances, and avoids feeding Link dust, improve product quality.

Description

technical field [0001] The invention belongs to the technical field of optical glass continuous melting. Specifically, it relates to an automatic feeding process and device for continuously adding batch materials for melting optical glass into a glass melting furnace through a ceramic screw propeller after continuous drying and dehydration. Background technique [0002] At present, most of the optical glass continuous melting production lines have realized automatic feeding. The feeding methods involved in the automatic feeding process mainly include timing and quantitative, timing and non-quantitative, and quantitative and non-timing, etc. These methods are all intermittent input, which will cause fluctuations in the glass liquid level in the melting pool and have a certain impact on product quality; The constant-speed continuous feeding method can maintain a stable liquid level, but because the temperature of the glass melting furnace is very high, it is impossible to est...

The feeding methods involved in the automatic feeding process mainly include timing and quantitative, timing and non-quantitative, and quantitative and non-timing, etc. These methods are all intermittent input, which will cause fluctuations in the glass liquid level in the melting pool and have a certain impact on product quality; The constant-speed continuous feeding method can maintain a stable liquid level, but because of the high temperature of the glass melting furnace, it is impossible to establish a continuous feeding channel with conventional materials, so the continuous feeding method is rarely used
