Description
Technical field
The utility model relates to optical field and manufactures field, specifically a kind of crucible of lanthanum.
Background technology
Platinum crucible can higher, the glass that clay crucible had to Eroded effect of Melting Quality, as heavy crown, dense barium flint, rare earth glass and fluorine phosphorous glass.Platinum crucible electrically heated, general employing globars or silicon molybdenum rod furnace.But manufacture tendency towards devitrification large, require cooling rapidly and atmosphere had certain requirements glass, then can adopt ratio-frequency heating.
The method of forming of opticglass has classic broken crucible method, rolling process and casting, but adopt leakage material shaping at present more and more widely, feed liquid is flowed out with single crucible or continuous smelting, can directly pull-rod or tear drop die mould or leak the shaping large-sized blank of material, improve gob utilization ratio and yield rate.
Single crucible of the opticglass of traditional way is produced the arm stirrer that adopts more and is stirred, and crucible body adopts single cylindrical design, but the design of single cylinder shape crucible body, it is many that glass metal when agitator can be made to expose glass metal remains quantitative change, thus affect the good article rate of product.In addition, for the glass kind that some volatility is stronger, single crucible body design of open type, can cause glass metal levels in crucible to there is component difference, thus affect the inner homogeneous of opticglass and the stability of product.
In addition, the glass melting temperature of opticglass generally equal high temperature more than 1000 degree, so crucible needs to adopt resistant to elevated temperatures material to make, since the sixties, various countries adopt the continuous tank furnace melting of liner platinum in succession, the output of opticglass is improved greatly, quality, this is the main trend of current opticglass production technique development.But platinum material is expensive, require that investment is large, difficulty or ease are born.
Summary of the invention
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide and a kind ofly single crucible can be made inner isolated with atmospheric sealing, can improve the hermetic type opticglass smelting pot of homogenization of glass effect and the low crucible for the production of opticglass of cost simultaneously.
The concrete technical scheme of a kind of opticglass of the utility model smelting pot is:
A kind of opticglass smelting pot, comprises crucible body, and described crucible body comprises large crucible chamber and the recessed little crucible chamber of this large crucible chamber bottom center; The upper port in large crucible chamber is provided with sealing groove and the sealing cover with sealing slot fit; Also comprise agitator, the blade of agitator is positioned at little crucible chamber; Lou material pipe is provided with bottom little crucible chamber; Large crucible chamber is provided with ventpipe; Described pot body comprises outermost metallic base layer, the high-temperature-resistant layer of innermost layer and the vacuum cavity layer that is arranged between this high-temperature-resistant layer and metallic base layer.
Described large crucible chamber and little crucible chamber are cylindrical body.
Described ventpipe is horizontally installed on the lower sides of large crucible chamber.
Described sealing groove is positioned at the outside of large crucible chamber upper port.
The thickness of described high-temperature-resistant layer is 5 ~ 20mm.
Described metallic base layer and high-temperature-resistant layer one-body molded.
The beneficial effects of the utility model:
The utility model existing by crucible body, leak material pipe, on the basis of the opticglass smelting pot that agitator is formed, crucible body is designed to large crucible chamber and is positioned at the pannikin chamber of large crucible chamber bottom center, the upper port in cauldron chamber is provided with sealing groove and sealing cover, agitator blades is positioned at pannikin chamber, leaking material pipe is arranged on the bottom surface in pannikin chamber, cauldron chamber is provided with ventpipe, thus add in the upper port sealing groove of cauldron chamber when carrying out opticglass melting and the glass of institute's smelting glass same breed in crucible body (adopting glass dregs to add) more, in sealing groove, glass melting becomes can to realize during glass metal that crucible is inner completely cuts off with atmospheric sealing, simultaneously, agitator blades stirs in pannikin chamber, agitator blades in the process of coming out of the stove can be avoided to expose too early because glass metal reduces gradually, strengthen mixing effect, improve the good article rate of product.The utility model has makes single crucible inside completely cut off with atmospheric sealing, can improve again the feature of homogenization of glass effect simultaneously.
In addition, crucible arranges high-temperature-resistant layer in metallic base layer, and between metallic base layer and high-temperature-resistant layer, adopt vacuum layer to isolate, and make crucible can meet high temperature resistant requirement, and reduce material cost, resistance toheat is also improved.
