Description
Technical field
The utility model relates to a kind of continuous induction melting furnace, particularly a kind of no core bar continuous induction melting furnace that draws quartz glass bar.
Background technology
The method of present domestic continuous smelting farad quartz glass bar processed has two kinds: a kind of is that former with the core bar lower end is processed into taper; can draw quartz glass bar; another kind is when drawing quartz glass tube; draw quartz glass bar as need; at first close shielding gas; install a vacuum pump additional in core bar ventilating pit upper end again, descending silica glass liquid is formed the suction state, can draw quartz glass bar.The defective of above-mentioned two kinds of technology is that its continuous induction melting furnace all must have core bar and former, and the quartz glass bar specification of pulling out is little, particularly has black core in the middle of the quartz glass bar, can't reach semi-conductor and integrated circuit manufacturing industry to the requirement of its quality.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provides a kind of reasonable in design, easy to use, does not have the no core bar continuous induction melting furnace of black core in the middle of the quartz glass bar.
Technical problem to be solved in the utility model is to realize by following technical scheme, the utility model is a kind of no core bar continuous induction melting furnace that draws quartz glass bar, comprise body of heater, be provided with the tungsten crucible in the body of heater, the tungsten crucible bottom is provided with the material platform, the material platform is provided with discharge port, the body of heater upper port is provided with the continuous smelting bell, be characterized in: described continuous smelting bell comprises bottom and loam cake, the middle part of bottom is provided with open holes, is provided with connecting cylinder in the open holes, fixedlys connected with loam cake in the upper end of connecting cylinder, the lower end inwall of connecting cylinder is provided with the boss that blocks the tungsten crucible, be provided with sealing mechanism between bottom and connecting cylinder, be provided with the top cover lifting regulating mechanism between bottom and loam cake, the top of loam cake is provided with top cover, top cover is fixedlyed connected with loam cake by fastening piece, and top cover is provided with charge cavity.
Technical problem to be solved in the utility model can also further realize by following technical scheme, described sealing mechanism comprises and is located at sealing-ring between bottom and the connecting cylinder, the top of sealing-ring is provided with pressing plate, and pressing plate is fixedlyed connected with bottom by web member.
Technical problem to be solved in the utility model can also further realize by following technical scheme, the top cover lifting regulating mechanism comprises the adjusting bolt that passes loam cake, the lower end of regulating bolt is fixed on the bottom, and the adjusting bolt of loam cake below is provided with fitting nut.
Technical problem to be solved in the utility model can also further realize that the upper surface of described material platform is tilted to down setting by tungsten crucible inwall to discharge port by following technical scheme.
There are not core bar and former in the utility model tungsten crucible, the silica glass liquid of fusion directly comes out from the discharge port of material platform under seamless state, black core in the middle of making it to have removed, simultaneously by becoming the continuous smelting bell split type, thereby make the tungsten crucible realize lift adjustment, can adjust the diameter of quartz glass bar by the lifting of tungsten crucible.
Compared with prior art, it is rational in infrastructure, and the specification of adjustable arthrolith English glass stick expands 2 to 60mm by existing 2 to 30mm, and no core bar draws the black core problem that has solved quartz glass bar.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Following with reference to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not constitute the restriction to its right.
With reference to Fig. 1, a kind of no core bar continuous induction melting furnace that draws quartz glass bar, comprise body of heater 1, be provided with tungsten crucible 3 in the body of heater 1, tungsten crucible 3 bottoms are provided with material platform 2, and material platform 2 is provided with discharge port, and the upper surface of described material platform 2 is tilted to down setting by tungsten crucible 3 inwalls to discharge port, can effectively control downstream rate and the flow of quartz glass bar like this, thereby regulate the diameter of quartz glass bar.
Body of heater 1 upper port is provided with the continuous smelting bell, and the continuous smelting bell comprises bottom 5 and loam cake 7, and the top of loam cake 7 is provided with top cover 10, is provided with silica gel sealing ring between loam cake 7 and the top cover 10, and top cover 10 is fixedlyed connected with loam cake 7 by fastening piece, and top cover 10 is provided with charge cavity 9.The middle part of described bottom 5 is provided with open holes, be provided with connecting cylinder 4 in the open holes, fixedly connected with loam cake 7 in the upper end of connecting cylinder 4, the lower end inwall of connecting cylinder 4 is provided with the boss that blocks tungsten crucible 3, between bottom 5 and connecting cylinder 4, be provided with sealing mechanism, described sealing mechanism comprises and is located at sealing-ring 11 between bottom 5 and the connecting cylinder 4, and the top of sealing-ring 11 is provided with pressing plate 6, and pressing plate 6 is fixedlyed connected with bottom 5 by web member 12.Be provided with the top cover lifting regulating mechanism between bottom 5 and loam cake 7, the top cover lifting regulating mechanism comprises the adjusting bolt 13 that passes loam cake 7, and the lower end of regulating bolt 13 is fixed on the bottom 5, and the adjusting bolt 13 of loam cake 7 belows is provided with fitting nut 8.By regulating the lifting of top cover lifting regulating mechanism, can drive 3 liftings of tungsten crucible simultaneously, tungsten crucible 3 rises, and it can enlarge the diameter of quartz glass bar, and tungsten crucible 3 descends and can dwindle the diameter of quartz glass bar.
In the process that draws, need to prolong the continuous induction melting furnace discharge port to the distance of rod drawer, extend to 2500mm by 2000mm, adjust pull-rod speed according to the diameter of quartz glass bar, diameter is more big, and speed is more slow.
