Description
[technical field]
The present invention relates to the artificial lens field, specifically the present invention relates to the adjustable combined type copple of a kind of volume.
[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 the adjustable combined type copple of a kind of volume, by crucible being divided into crucible and additional cylinder A, additional cylinder B, realized that fragile part can independently change, permanent partial can repeatedly use, and the inventor has obtained significantly reducing with respect to the prior art use cost.
In order to realize the purpose of foregoing invention, the present invention adopts following technical scheme:
The combined type copple that a kind of volume is adjustable comprises crucible, an additional cylinder A, on the crucible of crucible upper end along face be provided with around annular recess; The upper surface of additional cylinder A is the plane, be provided with in the lower surface of additional cylinder A around to the downward-extension protruding ring; Along the annular recess grafting of setting, described protruding ring is joined with the annular recess kiss and the adjustable combined type copple of formation volume is docked in the lower surface of additional cylinder A with edge on the crucible on the protruding ring that arranges on the described additional cylinder A lower surface and the crucible.
The combined type copple that described volume is adjustable is on the cavity in crucible, the inside face of additional cylinder A is respectively equipped with the barium coating.
The combined type copple that described volume is adjustable, the barium coat-thickness on the described crucible inner chamber body, on the additional cylinder A inside face is 1～2mm.
The combined type copple that described volume is adjustable is arranged on that the described annular recess on edge is " U " shape groove or " V " shape groove on the crucible; The protruding ring that is arranged on additional cylinder A lower surface is " U " shape projection or " V " shape projection.
The combined type copple that described volume is adjustable is provided with additional cylinder B between crucible and additional cylinder A, be respectively equipped with annular recess, protruding ring on the upper edge of the cylinder of described additional cylinder B and the lower surface.
The combined type copple that described volume is adjustable, the described annular recess that is arranged on edge on the additional cylinder B cylinder is " U " shape groove or " V " shape groove; The protruding ring that is arranged on additional cylinder B lower surface is " U " shape projection or " V " shape projection.
The combined type copple that described volume is adjustable is provided with the barium coating in the inside face of adding cylinder B.
The combined type copple that described volume is adjustable, the barium coat-thickness that arranges on the additional cylinder B inside face is 1～2mm.
By above-mentioned disclosure, the invention has the beneficial effects as follows:
The combined type copple that volume of the present invention is adjustable, by crucible being divided into crucible and additional cylinder A, also can increase additional cylinder B, in use by adding the combination of cylinder A, additional cylinder B and crucible, realized that fragile part can independently change, permanent partial can repeatedly use, and the inventor is through test, the time limit of service of additional cylinder A, additional cylinder B is more than 20 times of crucible, and guaranteed performance can not reduce; The invention enables the flimsy crucible of appearance bottom in time to change, the intact part in top is repeatedly used, although slightly be improved with respect to prior art tooling cost of the present invention, use cost 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 easily appears in quartz sand, so that occur unnecessary composition in silicon single crystal or the polysilicon, the barium coating that the present invention arranges at crucible, additional cylinder A and additional cylinder B can be guaranteed the quality of silicon single crystal.
