The utility model discloses can improve the heat source that the crucible was founded the temperature and was provided the large tracts of land, guarantee jumbo size quartz crucible overall dimension's formation, improve the interior watch crystal ization structure of crucible, improve quartz crucible's quality greatly.
Description
Technical field
The utility model relates to the electrode generation device of quartz crucible, is specifically related to a kind of large-diameter quartz crucible and founds electrode device.
Background technology
Current domestic quartz crucible is produced and is also rested on 22 cun-24 cun productions, large size 28 cun of-32 cun of quartz crucibles also dependence on import, the technique of domestic production large size quartz crucible is also immature, run into various problem in process of production, comprise quartz crucible profile when founding not up to standard, quartz crucible inner surface vitrifying degree is low causes crystal pulling distortion etc., the key factor temperature of founding when major cause still manufactures large size quartz crucible can not reach reasonable request, quartz crucible utilizes glass sand to found to form, the fusing point of quartz sand is at about 1750 DEG C, abundant fusing possibility temperature is higher, the obvious difference of large size quartz crucible and small size quartz crucible is that the external diameter of crucible is large, wall thickness is thick, when normal process is founded, utilize three electrifying electrodes to put production temperature requirement that arc can meet 22 cun of-24 cun of crucibles, but the raw material of mould inner surface can not fully melt by the temperature of three electrode generations in large size mould when production large size quartz crucible, temperature flow is also lost greatly, extend the large DeGrain of melting time energy consumption, quartz crucible physical dimension is caused to be difficult to be formed, the vitrifying degree of internal surface also can reduce accordingly, crucible quality is caused to decline, easily there is a lot of problem in quartz crucible in pulling monocrystal process, distortion, crystallization, easy broken string etc.
Utility model content
Goal of the invention: the purpose of this utility model is the deficiency solving prior art existence, provides a kind of large-diameter quartz crucible to found electrode device.
Technical scheme: a kind of large-diameter quartz crucible described in the utility model founds electrode device, comprise graphite jig and Graphite Electrodes assembly, described Graphite Electrodes assembly comprises the six roots of sensation Graphite Electrodes inserted in graphite jig, the top of six roots of sensation Graphite Electrodes is vertically connected to the copper rod above electrode, the top of each copper rod described clamps respectively by jaw, one end of six jaws is connected to chassis all equably, the other end of jaw is connected with feed screw nut by connecting rod, the rotation of the mobile screw mandrel on feed screw nut top realizes driving feed screw nut's rise and fall, feed screw nut pulls six jaws to drive copper rod open closed.
Further, produce arc-shaped electric arc after described six roots of sensation Graphite Electrodes energising, and in six roots of sensation Graphite Electrodes, often between adjacent two electrodes, produce the electric arc of continous-stable, between two electrodes separately, do not produce continuous print electric arc.
Further, the top of described six roots of sensation Graphite Electrodes is connected with motor to control open and close.
Further, described chassis is rounded.
Beneficial effect: the utility model utilizes six electrodes device production large size quartz crucible, in the process of arc melting quartz crucible, six roots of sensation Graphite Electrodes is energized the starting the arc in graphite jig, by electric arc, the quartz sand of graphite jig inwall is melted, the final quartz crucible that formation is similar with mould present situation in graphite jig, the utility model can improve crucible melting temperature and provide large-area thermal source, ensure the formation of large size quartz crucible physical dimension, improve inner surface of crucible vitrifying structure, substantially increase the quality of quartz crucible.

Embodiment
Below technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
As depicted in figs. 1 and 2, a kind of large-diameter quartz crucible of the present utility model is founded electrode 2 device and is comprised graphite jig and Graphite Electrodes 2 assembly, Graphite Electrodes 2 assembly comprises the six roots of sensation Graphite Electrodes 2 inserted in graphite jig, the top of six roots of sensation Graphite Electrodes 2 is hexagonal configuration by the equally spaced arrangement of web member, and the top of all Graphite Electrodess 2 is connected with the quiet youngster of motor and can opens simultaneously and close; Described Graphite Electrodes 2 comprises electrode 2 and is vertically connected to the copper rod 1 above electrode 2, the top of each copper rod 1 described clamps respectively by jaw 3, one end of six jaws 3 is connected to chassis 4 all equably, the other end of jaw 3 is connected with feed screw nut 6 by connecting rod 5, the rotation of the mobile screw mandrel 6 on feed screw nut 6 top realizes driving feed screw nut 6 rise and fall, and feed screw nut 6 pulls six jaws 3 to drive copper rod 1 open closed.
Produce arc-shaped electric arc after above-mentioned six roots of sensation Graphite Electrodes 2 is energized, and often produce the electric arc of continous-stable between adjacent two electrodes 2 in six roots of sensation Graphite Electrodes 2, between two electrodes 2 separately, do not produce continuous print electric arc.
In Graphite Electrodes 2 assembly of the present embodiment, six roots of sensation Graphite Electrodes 2 can simultaneously action, that is: the open and close of control electrode 2 is carried out by the driven by motor screw mandrel on six roots of sensation Graphite Electrodes 2 top, and the distance controlled between each electrode 2, spacing between electrode 2 is in 0-10cm scope, by calculating when equal electrode 2 spacing, the equilateral triangle area of three electrode 2 formation will be far smaller than the equilateral hexagon of six electrodes 2 formation, the heating source area namely formed is far longer than the thermal source that three electrodes 2 are formed, meet the thermal requirement that major diameter crucible is produced, and the length of electric arc can be controlled by the spacing of electrode 2 when the starting the arc.
Six roots of sensation Graphite Electrodes 2 power supply in the utility model connects as shown in Figure 3, adopts three-phase alternating current, each phase intervals connection electrode 2, and after ensureing the starting the arc, homophase power supply does not play arc discharge.
