Abstract

The invention discloses continuous melting equipment for sulfur infrared glass, and relates to the technical field of preparation of sulfur infrared glass. A continuous production line is formed and is short in production period, large in production power, optional in product size and high in optical homogeneity. The main technical scheme is that the equipment includes at least two melting apparatuses, a homogenizing apparatus, a shaping apparatus, and an annealing apparatus. The melting apparatuses are used for purifying glass raw materials and melting the glass raw materials into a glass liquid. A first feeding port of the homogenizing apparatus communicates with the melting apparatuses for clarifying and homogenizing the glass liquid flowing from the first feeding port. A second feeding port of the shaping apparatus communicates with a second discharge port of the homogenizing apparatus for leaking and discharging the homogenized glass liquid. The obtained product is cooled at a shaping part to obtain a glass blank. A transmission mechanism of the annealing apparatus is arranged below the shaping part, and an annealing structure is arranged above the transmission mechanism and used for annealing and cooling the glass blank transferred through the transmission mechanism. The at least two melting apparatuses continuously provide the glass liquid for the homogenizing apparatus.

Description

technical field [0001] The invention relates to the technical field of preparation of chalcogenide infrared glass, in particular to continuous melting equipment for chalcogenide infrared glass. Background technique [0002] Chalcogenide infrared glass refers to a type of non-oxide glass formed by the main elements of group VIA such as S, Se, Te and the introduction of other elements. Chalcogenide infrared glass has mid-to-far infrared transmission performance similar to that of single crystal germanium, and the transmission band (0.9-15 μm) covers three infrared atmospheric windows. At the same time, chalcogenide infrared glass has good light-thermal stability characteristics, and the temperature coefficient of refractive index is only 10% to 30% of that of single crystal germanium, which is conducive to improving the temperature adaptive ability of infrared thermal imaging optical system and meeting the athermalization design Require. Chalcogenide infrared glass can be fo...
