Description
Technical field
The utility model relates to a kind of quartz glass continuous induction melting furnace, is applicable to the production of silica tube, quartz pushrod and quartz plate.
Background technology
At present, highly purified silica tube, quartz pushrod and quartz plate are all to produce by quartz continuous melting furnace, existing quartz continuous melting furnace heating unit adopts external heat more, on crucible excircle, heating unit is set, by radiative transfer, crucible is heated, make the silica powder in crucible be melt into liquid state, and then draw moulding.Existing heating unit is owing to longitudinally arranging, and crucible diameter is longitudinally consistent, thus crucible be heated comparatively even, and silica powder is entered after crucible by filling tube, need carry out preheating, melting and exhaust moulding process, for keeping the mobility of fluid, require the temperature of melting zone higher.And the underheating of existing type of heating to crucible materials inside, easily causes inner fusing inhomogeneous, affects quality product.
Utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: a kind of quartz glass continuous induction melting furnace is provided, and reasonable in design, meet the temperature requirement of crucible regional, make heating material even, improve the quality of products.
Quartz glass continuous induction melting furnace described in the utility model, comprise body of heater, bell, in body of heater, be provided with crucible, crucible outside is provided with main heating unit, and crucible center is provided with core bar, core bar bottom binder platform, core bar upper end connects bell, and crucible is comprised of upper crucible and lower crucible, and upper crucible and lower crucible are in smoothing junction, and lower crucible diameter is less than crucible diameter, in upper crucible, be provided with auxiliary heating unit.
The corresponding preheating zone of upper crucible, the corresponding melting zone of lower crucible and exhaust area, by different diameters is set, make the inventory in different zones different, due to the inventory having reduced in time crucible, under the constant condition of main heating unit heating power, the comparatively high temps that guarantees melting zone, carries out interval heating by auxiliary heating unit is set, and makes the inside heating of material more even, avoid the generation of bubble, gas line, improve the quality of products.Meanwhile, in the blowing out stage, by auxiliary heating unit, the silica powder fusing of upper of furnace body is flowed out, avoid quartz to stick on crucible inwall.
Described upper crucible is than the large 30mm～50mm of lower crucible diameter.
Described upper crucible and lower crucible aspect ratio are 1:1.
Described auxiliary heating unit comprises auxiliary electrode and additional hot pin, and auxiliary electrode is arranged on upper of furnace body, and additional hot pin is circumferentially uniform along upper crucible, and additional hot pin can adopt tungsten bar, arranges that quantity is 4～6.
1/3～1/2 place of described additional hot pin between core bar and upper crucible inwall, the positional distance center core bar of additional hot pin is nearer, to improve the temperature of material inside, makes bulk temperature even.
Silica powder is entered in crucible by filling tube, carries out preheating in upper crucible, then enters lower crucible and carries out melting exhaust, finally by material platform, pulls out moulding.By main heating unit, crucible periphery is heated, because lower crucible diameter is less than upper crucible diameter, material in therefore lower crucible is less than crucible, thereby guaranteed the high-temperature of melting zone, meanwhile, because the internal diameter of lower crucible is little, laterally heat transfer rate is fast, the material stream of melting is heated evenly, avoids producing bubble, gas line.Auxiliary heating unit can be interrupted heating, so that material keeps transverse temperature even in upper crucible.Meanwhile, in the blowing out stage, by auxiliary heating unit, the silica powder fusing of upper of furnace body is flowed out, avoid quartz to stick on crucible inwall.
Compared with prior art, the beneficial effect the utlity model has is:
This quartz glass continuous induction melting furnace is reasonable in design, by upper crucible, lower crucible and auxiliary heating unit are set, meets the temperature requirement of crucible regional, makes heating material even, avoids producing bubble, gas line, improves the quality of products.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, body of heater; 2, thermal insulation layer; 3, main heating unit; 4, material platform; 5, crucible; 6, core bar; 7, auxiliary heating unit; 8, bell; 9, filling tube; 10, nut; 501, lower crucible; 502, upper crucible.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, this quartz glass continuous induction melting furnace comprises body of heater 1, bell 8, in body of heater 1, be provided with crucible 5, crucible 5 outsides are provided with main heating unit 3, and crucible 5 centers are provided with core bar 6, core bar 6 bottom binder platforms 4, core bar 6 upper ends connect bell 8, core bar 6 upper end joint nuts 10, regulate core bar height by nut 10, and bell 8 is provided with uniform filling tube 9.Crucible 5 is comprised of upper crucible 502 and lower crucible 501, upper crucible 502 and lower crucible 501 smooth connections, and lower crucible 501 diameters are less than crucible 502 diameters, the desirable 30mm～50mm of its difference, and both aspect ratios are 1:1.In upper crucible 502, be also provided with auxiliary heating unit 7, auxiliary heating unit 7 comprises auxiliary electrode and additional hot pin, auxiliary electrode is arranged on body of heater 1 top, additional hot pin is circumferentially uniform along upper crucible 502, and its quantity is 4～6,1/3～1/2 place of additional hot pin between core bar 6 and upper crucible 502 inwalls, preferred 1/3 place, make the positional distance center core bar 6 of additional hot pin nearer, to improve the temperature of material inside, make bulk temperature even.
Silica powder is entered in crucible 5 by filling tube 9, in upper crucible 502, carries out preheating, then enters lower crucible 501 and carries out melting exhaust, finally by material platform 4, pulls out moulding.By 3 pairs of crucible 5 peripheries of main heating unit, heat, because lower crucible 501 diameters are less than upper crucible 502 diameters, material in therefore lower crucible 501 is less than crucible 502, thereby guaranteed the high-temperature of melting zone, meanwhile, because the internal diameter of lower crucible 501 is little, laterally heat transfer rate is fast, the material stream of melting is heated evenly, avoids producing bubble, gas line.Auxiliary heating unit 7 can be interrupted heating, so that the interior material of upper crucible 502 keeps transverse temperature even.Meanwhile, in the blowing out stage, by auxiliary heating unit 7, the silica powder fusing on body of heater 1 top is flowed out, avoid quartz to stick on crucible 5 inwalls.
