Description
Technical field
The utility model relates to a kind of structure of opticglass melting pool, particularly relates to a kind of for improving crucible structure in the high melting pool reflecting lanthanide optical glass bubble quality.
Background technology
Along with the expansion of opticinstrument use range and the raising of precision, and precision optical instrument, optical information communication, O-E Products field develop rapidly, increasing to the demand of special optical glass, require also more and more higher.For optical design and the optical communication of development, specific refractory power more than 1.9 opticglass is of great significance simplification Optical System Design, raising image quality, Optical Communication Technology Development tool.
During current opticglass melting, structure generally main employing two kinds of forms of melting pool, a kind of is independent outer crucible structure, another kind is that crucible is interior outside increases a dash plate, although the second structure can play the effect of buffering, prevent the impact of the external crucible of frit added, affect the work-ing life of outer crucible, but this structure still can not meet the production of opticglass, bubble is difficult to eliminate, melting pool material situation can not ensure, cause that raw materialization are good just directly flows to settling pond portion, particularly for above-mentioned specific refractory power more than 1.9 height refraction lanthanide optical glass, this problem is particularly outstanding.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of interior crucible structure effectively can improving the opticglass melting pool of bubble quality.
The technical scheme that the utility model technical solution problem adopts is: the interior crucible structure of opticglass melting pool, comprises interior crucible main body, below described interior crucible main body, be provided with supporting seat, and described interior crucible bottom part body has through hole.
Further, described through hole is several.
Further, described through hole is 16.
Further, the diameter of described through hole is not less than Ф 5mm and is not more than Ф 20mm.
Further, the setting of described through hole divides two ring layers.
Further, the first ring layer lead to the hole site of described two ring layers is not less than 50mm from bottom centre's point distance and is not more than 150mm; Second ring layer lead to the hole site is not less than 200mm from bottom centre's point distance and is not more than 450mm.
Further, described interior crucible main body is hemispherical.
Further, the radius of described interior crucible main body hemisphere is not less than 200mm and is not more than 400mm.
Further, edge, described interior crucible main body upper end is provided with crucible edge.
Further, the width dimensions on described crucible edge is not less than 5mm and is not more than 20mm.
The beneficial effects of the utility model are: the through hole of interior crucible bottom part body can play guide functions to glass metal, glass metal is flowed according to specified path, fully can ensure the data consistency of glass metal at melting pool, the gas ratio of glass metal at melting pool can be ensured simultaneously, be conducive to glass metal carries out glass blister defect elimination at subsequent process.The utility model creatively arranges a bottom again and has crucible in through hole in the outer crucible of existing melting pool, not only can play the effect of buffering, prevent the impact of the external crucible of frit added, can also effectively improve glass blister quality simultaneously, improve glass blister quality stability, the utility model is specially adapted to the bubble quality of the height refraction lanthanide optical glass improving specific refractory power more than 1.9.
Accompanying drawing explanation
