Description

A kind of guide shell for magnetic field single crystal growing furnace

Technical field

The utility model relates to single crystal growing furnace producing apparatus field, particularly relates to a kind of guide shell for magnetic field single crystal growing furnace.

Background technology

In CZ 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 22 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 guide shell for magnetic field single crystal growing furnace, 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 guide shell for magnetic field single crystal growing furnace, it comprises weight 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 guide shell body comprises the first guide shell and the second guide shell, it is inner that described second guide shell is arranged on the first guide shell, it also comprises clip, connecting rod and hook, described hook is evenly arranged on above the second guide shell, and the end of hook is bent downwardly, described clip is arranged on weight, 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, described hook has three at least;

Further, the material of described hook, connecting rod and clip is molybdenum;

The utility model, at increase connecting rod, clip and hook, pulls hook by connecting rod, drives the second guide shell, thermal field space is increased, thus increases a charging capacity, connect different projections by connecting rod, the height that the second guide shell rises can be controlled, thus control charging capacity.

The beneficial effects of the utility model

1. the utility model is by the cooperation of connecting rod and hook, drives the second guide shell, thermal field space is increased, thus increases a charging capacity.

2. the utility model structure is simple, and cost is low, can control charging capacity.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of guide shell for magnetic field single crystal growing furnace described in the utility model specific embodiment;

In accompanying drawing, the list of parts representated by each label is as follows:

1, weight, 2, guide shell body, the 3, first guide shell, the 4, second guide shell, 5, clip, 6, connecting rod, 7, hook, 8, projection.

Embodiment

Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.

A kind of guide shell for magnetic field single crystal growing furnace, it comprises weight 1 and guide shell body 2, described weight 1 is arranged on above guide shell body 2, described guide shell body 2 is tubular structure penetrating up and down, described guide shell body 2 comprises the first guide shell 3 and the second guide shell 4, it is inner that described second guide shell 4 is arranged on the first guide shell 3, it also comprises clip 5, connecting rod 6 and hook 7, described hook 7 is evenly arranged on above the second guide shell 4, and the end of hook 7 is bent downwardly, described clip 5 is arranged on weight 1, and multiple projection 8 is evenly installed outside clip 5, described connecting rod 6 connects projection 8 and hook 7, and the number of connecting rod 6 is consistent with the number of hook 7, described hook 7 has three at least, described hook 7, the material of connecting rod 6 and clip 5 is molybdenum,

The utility model is in use:

1. first make hook 7, clip 5 and connecting rod 6 with material molybdenum;

2. hook 7 is evenly arranged on guide shell body 2;

3. on weight 1, clip 5 is installed, connecting rod 6;

4. to sling guide shell body 2 after charging, thermal field space is increased, thus increases a charging capacity.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
