Description
Technical field
The utility model relates to single crystal growing furnace producing apparatus field, particularly relates to a kind of low-oxygen monocrystal thermal field guide shell.
Background technology
In MCZ monocrystalline silicon growing method, disposable quartz crucible price is higher, so charging capacity is to production cost important, the charging capacity so increasing every heat becomes an important means reduced costs, and 18 cun of this large-scale thermal fields of thermal field especially need increase charging capacity, density (2.33) because of element silicon solid form is less than the density of its liquid form, so restriction is caused to total charging capacity in space in the process of feeding intake, prior art is often by directly increasing container, charging capacity is increased with this, which increase cost, and cannot control charging capacity.
Utility model content
The purpose of this utility model is to provide a kind of low-oxygen monocrystal thermal field guide shell, can increase charging capacity by the utility model, reduces production cost.
The technical scheme that the utility model solves the problem is:
A kind of low-oxygen monocrystal thermal field guide shell, it comprises weight, insulation cover and guide shell body, described weight is arranged on above guide shell body, described guide shell body is tubular structure penetrating up and down, described insulation cover is arranged on guide shell body both sides, it also comprises clip, Fixed latches and connecting rod and hook, described hook even level is arranged on above guide shell body, and the end of hook is bent downwardly, described Fixed latches is arranged on below weight, described clip is arranged on the end of Fixed latches, and outside clip, multiple projection is evenly installed, described connecting rod connects projection and hook, and the number of connecting rod is consistent with the number of hook,
On the basis of technique scheme, the utility model can also do following improvement,
Further, it also comprises back-up ring, and described back-up ring is arranged between insulation cover and guide shell, and back-up ring is ladder structure;
Further, described hook has three at least;
Further, the material of described hook, connecting rod, Fixed latches and clip is molybdenum;
The utility model installs Fixed latches on weight, clip is arranged on the end of Fixed latches, ensure that easy accessibility, by Fixed latches, is convenient to installation and the movement of hook, can be used for multiple table; Hook changes level into and installs, and increases stressed area, increases the service life.
The beneficial effects of the utility model
1. the utility model is by the cooperation of connecting rod and hook, drives guide shell, thermal field space is increased, thus an increase charging capacity;
2. the utility model changes the installation form of clip, easy for removal and installation, changes the mounting means of hook, increases stressed area, increases the service life;
3. the utility model structure is simple, and cost is low, can control charging capacity.
Accompanying drawing explanation
