Embodiment

[0056] Adopt the manufacturing method of the present invention to manufacture fluorophosphate optical glass clinker, the composition of fluorophosphate optical glass contains SiO in mass percent 2 : 30%, BaO: 20%, F: 15%, P 2 o 5 : 20%, La 2 o 3 : 5%, Na 2 O: 5%, B 2 o 3 : 5%, the manufacturing process is as follows:

[0057] S1. Add the glass raw material into the smelting zone of the inner cavity of the smelting container 2 through the feeder 1, and then heat the glass raw material added to the smelting zone through the heating device to melt it into molten glass, continue to heat the molten glass and pass it through the lower drum Bubble tube 10 blows gas to the molten glass in the smelting zone to homogenize it;

[0058] S2, the homogenized molten glass flows into the discharge area through the glass liquid hole at the bottom of the vertical partition 9, and then discharges the glass liquid in the discharge area to the feeding front end of the conveyor belt 11 throu...

Abstract

The invention belongs to the technical field of glass production, particularly discloses a manufacturing device and a manufacturing method of optical glass clinker, and aims at solving the problem that an existing device for manufacturing fluorophosphate optical glass clinker is low in production efficiency. According to the manufacturing device, a vertical partition plate is arranged in the inner cavity of a smelting container to divide the inner cavity into a smelting area and a discharging area, and a molten glass passing hole for communicating the smelting area with the discharging area is formed in the lower portion of the vertical partition plate, so that molten glass can be smelted and homogenized in the smelting area, then flows into the discharging area through the molten glass passing hole, then is discharged through a discharging pipe for producing the glass clinker. Therefore, glass raw materials are fed into the smelting area in the production process, it is ensured that molten glass can be discharged outwards all the time in the discharging area, uninterrupted production of the glass clinker can be achieved, and the production efficiency is greatly improved. By arranging a traction annealing furnace with a cooling channel, the production efficiency can be further improved, meanwhile, the labor intensity of workers is greatly reduced, and the input-output rate can be increased.

Description

technical field [0001] The invention belongs to the technical field of glass production, and in particular relates to a manufacturing device and a manufacturing method of optical glass clinker. Background technique [0002] Fluorophosphate optical glass is suitable as a lens material for eliminating high-order chromatic aberration in optical design due to its low dispersion and special dispersion properties. Because this type of glass contains a lot of fluoride, it is easy to volatilize during the melting process, resulting in unstable components. Therefore, most of the production process is to first melt the fluorophosphate optical glass raw material into clinker, and then process the clinker. The secondary melting ensures the stability of fluorophosphate optical glass melting. [0003] At present, the process of producing fluorophosphate optical glass clinker is produced one pot at a time. When each pot is produced, the glass raw material powder is put into a single cruci...
