Abstract
This utility model relates to a kind of crucible, especially a kind of adjustable graphite crucible.Comprising: ring-shaped graphite clip, cylinder and graphite base plate, the end face of described graphite base plate offers annular slot, described cylinder is the truncated cone-shaped that the big base diameter of top diameter of hollow is little, described cylinder is made up of some pieces of graphite protective plate splits successively, it is positioned in annular slot bottom described graphite protective plate, the internal face of described cylinder fits tightly with the outside wall surface of the silica crucible with pattern draft, and described graphite clip hoop is in cylinder top.It efficiently solves problem that monoblock type graphite crucible generated heat by sensing, be inconvenient to the problem dismantled and the problem that adjacent plates cannot mutually support, backplate gap is inconvenient to adjust, be easily generated electric spark that split-type graphite crucible backplate exists, and between graphite crucible and silica crucible, there is gap, it is impossible to fit tightly the problem that silica crucible is effectively supported.
Description
Technical field
This utility model relates to a kind of crucible, especially a kind of adjustable graphite crucible.
Background technology
Graphite crucible is applied in the thermal field of polysilicon directional freezing equipment, to circular quartz crucible
It is supported protection.The effect of graphite crucible is to support silica crucible deflection when hot mastication
Less than setting value.There is pattern draft during due to circular quartz crucible molding, cause silica crucible
Opening diameter is big, and base diameter is little, if using the graphite crucible of straight barrel type, then silica crucible
Bottom can not obtain effective support of graphite crucible.
At present, two kinds of graphite crucibles of main employing in polysilicon industry directional solidification.The first is
Using overall graphite ring type crucible, the weak point of this type of graphite crucible is: (1) installs not side
Just；(2) use cost is higher；(3) ring-type graphite can be felt by electromagnetic field in induction furnace
Should, induction heating, make thermal field generation large change.The second is to use point board-like earthenware of lobe graphite
Crucible, the weak point of this type of graphite crucible is: have gap between (1) graphite protective plate, adjacent protects
Plate cannot mutually support, and can cause danger when crucible ruptures；(2) installing inconvenience, graphite protects
There is clearance requirement between plate, adjust inconvenience；(3) split-type graphite crucible in induction furnace also
Can be sensed by electromagnetic field, between adjacent plates, be produced electric spark, silica crucible is had certain danger
Evil.The general character weak point that above two graphite crucible exists is: graphite crucible and silica crucible
Between there is gap, it is impossible to fit tightly and silica crucible effectively supported.
Utility model content
This utility model aims to provide a kind of adjustable graphite crucible, and it efficiently solves monoblock type
Problem that graphite crucible is generated heat by sensing, be inconvenient to the problem dismantled and split-type graphite crucible protects
The adjacent plates that plate exists cannot mutually support, backplate gap is inconvenient to adjust, be easily generated electricity fire
The problem of flower, and between graphite crucible and silica crucible, there is gap, it is impossible to it is right to fit tightly
The problem that silica crucible effectively supports, its technical scheme used is as follows:
A kind of adjustable graphite crucible, it is characterised in that including: ring-shaped graphite clip, cylinder
With graphite base plate, the end face of described graphite base plate offers annular slot, and described cylinder is hollow
The little truncated cone-shaped of the big base diameter of top diameter, described cylinder is by some pieces of graphite protective plate successively
Split forms, and is positioned in annular slot, the internal face of described cylinder bottom described graphite protective plate
Fitting tightly with the outside wall surface of the silica crucible with pattern draft, described graphite clip hoop is in cylinder
Body top.
The definition of round platform is: remove truncated cone by a plane being parallel to circular cone bottom surface, bottom surface with
Part between cross section is called round platform or is perpendicular to the waist place straight line on base with right-angled trapezium and is
Rotary shaft, the solid that the curved surface that remaining each limit rotates and formed is surrounded is called round platform.
On the basis of technique scheme, fit tightly between adjoining graphite backplate.
This utility model has the advantage that efficiently solving monoblock type graphite crucible is sent out by sensing
The problem of heat, be inconvenient to the problem dismantled and the adjacent plates of split-type graphite crucible backplate existence
Cannot mutually support, the problem of electric spark is inconvenient to adjust, be easily generated in backplate gap, Yi Jishi
Gap is there is, it is impossible to fit tightly and silica crucible is carried out effectively between ink crucible and silica crucible
The problem supported.

, it is only used for explaining this utility model, and it is not intended that to restriction of the present utility model.
As depicted in figs. 1 and 2, a kind of adjustable graphite crucible, it is characterised in that including:
Ring-shaped graphite clip 1, cylinder 2 and graphite base plate 3, the end face of described graphite base plate 3 is offered
The round platform that the big base diameter of top diameter that has annular slot 30, described cylinder 2 to be hollow is little
Shape, described cylinder 2 is made up of some pieces of graphite protective plate 20 splits successively, described graphite protective plate
Be positioned over bottom 20 in annular slot 30, the internal face of described cylinder 2 with there is pattern draft
The outside wall surface of silica crucible 4 fit tightly, described graphite clip 1 binds round in cylinder 2 top.
On the basis of technique scheme, preferably fit tightly between adjoining graphite backplate 20.
Described graphite protective plate 20 can be four pieces.
During use, assembling sequence is: be placed on by silica crucible on graphite base plate, then by graphite
Backplate around silica crucible and be arranged on graphite base plate draw-in groove in, then graphite clip is installed to
In graphite protective plate, all of graphite protective plate is fixed, is completed.
After graphite crucible assembles, it would be desirable to the polysilicon block of melting puts into silica crucible,
Entirety is inserted in directional purification stove, starts melting.
The most by way of example this utility model is illustrated, but this utility model is not limited to
Above-mentioned specific embodiment, all any changes done based on this utility model or modification belong to this
The scope that utility model is claimed.
It is pointed out that the reference numeral described in claims is provided purely for auxiliary practicality
