Description
[technical field]
The present invention relates to the artificial lens field, specifically the present invention relates to a kind of tungsten cylinder to the volume regulation structure of quartz crucible.
[background technology]
Known, artificial lens is of a great variety, and the silicon single crystal that wherein uses in the solar electrical energy generation, polysilicon play indispensable effect in field of solar thermal power generation; In work sheet crystal silicon, polysilicon, usually can use crucible to draw or annotate ingot, quartz crucible is comparatively commonly used in the drawing of silicon single crystal, polysilicon or the notes ingot; Use crucible to draw or annotate ingot, first silicon single crystal or the polysilicon fragment pulverized are put into crucible, then utilize the interior heating jacket around the crucible outside of airtight furnace chamber that the silicon single crystal in the crucible or polysilicon fragment are melted, inserted slowly lifting in the brilliant liquid that melts by the seed crystal on the drawing device, form lens cylinder, described lens cylinder is the finished product crystal bar; Or utilize the interior heating jacket around the crucible outside of airtight furnace chamber that the silicon single crystal in the crucible or polysilicon fragment are melted, when melting silicon single crystal or polysilicon fragment, make crucible bottom formation a little less than the low-temperature region on top by the control heating jacket, the step temperature that is commonly called as of this area namely, the seed crystal that does not melt by being arranged on crucible bottom, make the brilliant liquid crystallization that reduces in the temperature crucible, form crystal ingot.
In the said process, because silicon single crystal or polysilicon fragment gap are larger in the crucible, so that silicon single crystal or the polycrystalline silicon wafer liquid measure of melting are less, if be processed into the crucible of the large degree of depth, the crucible that stands worked crystal post or crystal ingot can only use just can be scrapped in several days, mainly was the damage of crucible bottom, and top but is intact, cause serious waste, the crucible silicon single crystal that the degree of depth is less or the brilliant liquid measure of polycrystalline silicon wafer are less.
[summary of the invention]
In order to overcome the deficiency in the background technology, the invention discloses a kind of tungsten cylinder to the volume regulation structure of quartz crucible, by add the cylinder of tungsten or molybdenum materials matter at quartz crucible, utilize weather resistance and the high-temperature stability of tungsten or molybdenum, so that the height of quartz crucible reduces, effectively reduce quartzy usage quantity, significantly reduced use cost.
In order to realize the purpose of foregoing invention, the present invention adopts following technical scheme:
A kind of tungsten cylinder comprises quartz crucible, tungsten or molybdenum cylinder to the volume regulation structure of quartz crucible, on the crucible of quartz crucible along be provided with around annular recess; Or quartz crucible in cavity top be provided with extension diameter section, form step between the lower cavity of described extension diameter section and quartz crucible; The lower end of tungsten or molybdenum cylinder is inserted in the annular recess that the edge arranges on the crucible, and the lower end of described tungsten or molybdenum cylinder and annular recess kiss are joined; Or the lower end of tungsten or molybdenum cylinder is inserted on the step of quartz crucible inner chamber body extension diameter section lower cavity, and the lower end outer wall of tungsten or molybdenum cylinder and extension diameter section kiss are joined.
Described tungsten cylinder is to the volume regulation structure of quartz crucible, and the cavity wall in quartz crucible comprises that step is provided with the barium coating.
Described tungsten cylinder is to the volume regulation structure of quartz crucible, and described barium coat-thickness is 1～2mm.
By above-mentioned disclosure, the invention has the beneficial effects as follows:
Tungsten cylinder of the present invention is to the volume regulation structure of quartz crucible, by add the cylinder of tungsten or molybdenum materials matter at quartz crucible, utilize weather resistance and the high-temperature stability of tungsten or molybdenum, so that the height of quartz crucible reduces, effectively reduce quartzy usage quantity, significantly reduced use cost; Use cost of the present invention has obtained significantly reducing, and stability is higher when melting crystal; The material that crucible of the present invention uses is quartz sand, in view of mixing of quartz sand composition and silicon single crystal or polysilicon at high temperature appears in quartz sand easily, so that occur unnecessary composition in silicon single crystal or the polysilicon, the barium coating that the present invention arranges in quartz crucible can be guaranteed the quality of silicon single crystal.

[embodiment]
Below in conjunction with embodiment the present invention is further detailed; The following examples are not for restriction of the present invention, and only as supporting to realize mode of the present invention, any equivalent structure in technological frame disclosed in this invention is replaced, and is protection scope of the present invention;
The tungsten cylinder that provides in 1～3 by reference to the accompanying drawings comprises quartz crucible 5, tungsten or molybdenum cylinder 1 to the volume regulation structure of quartz crucible, on the crucible of quartz crucible 5 along 3 be provided with around annular recess 4; 3 structures that provide by reference to the accompanying drawings, cavity 2 tops in the described quartz crucible 5 are provided with extension diameter section 7, formation step 6 between the lower cavity 2 of described extension diameter section 7 and quartz crucible 5; The lower end of tungsten or molybdenum cylinder 1 is inserted on the crucible along in 3 annular recess 4 that arrange, and the lower end of described tungsten or molybdenum cylinder 1 is kissed with annular recess 4 and joined; Or the lower end of tungsten or molybdenum cylinder 1 is inserted on the step 6 of quartz crucible 5 inner chamber body 2 extension diameter sections 7 lower cavity 2, and the lower end outer wall of tungsten or molybdenum cylinder 1 and extension diameter section 7 kisses are joined, and cavity 2 walls in quartz crucible 5 comprise that step 6 is provided with the barium coating that thickness is 1～2mm.
Implement tungsten cylinder of the present invention to the volume regulation structure of quartz crucible, the present invention is by highly reducing quartz crucible 5, utilize tungsten or molybdenum cylinder 1 to stop silicon single crystal or the polysilicon fragment that does not melt, during use silicon single crystal or polysilicon fragment are piled in the quartz crucible 5 that comprises tungsten or molybdenum cylinder 1, the brilliant liquid of heating and melting sinks, brilliant liquid can not outflow by the butt seam between tungsten or molybdenum cylinder 1 and quartz crucible 5, brilliant liquid can not contact with tungsten or molybdenum cylinder 1 substantially, so that the silicon single crystal or the polycrystalline silicon wafer liquid that melt are present in the cavity 2 of quartz crucible 5, then just can implement to draw or annotate ingot, nonexpondable quartz crucible 5 is changed, and described tungsten or molybdenum cylinder 1 can use by plural number.
