Abstract

The utility model discloses a crystal growth composite crucible, which comprises a crucible body and a lengthened crucible tube, wherein the crucible body and the lengthened crucible tube are sleeved through positioning matching surfaces; the positioning matching surfaces are sleeved in a manner of cylindrical surfaces or circular conical surfaces. The utility model has the benefits that the crucible adopts the vertical composite structure, so that the crucible body can be connected with the lengthened crucible tube through the positioning matching surfaces; the positioning matching surfaces are cylindrical surfaces or circular conical surfaces; the crucible body can achieve the normal service life, and the lengthened crucible tube can be reused for many times, so that the comprehensive service life of the crucible is prolonged, and the manufacture cost is reduced; further, the crystal growth composite crucible has a simple structure, is easy to manufacture, and is convenient to use.

Description

The crystal growth composite crucible

Technical field

The utility model belongs to crystal and prepares equipment technical field, relates to a kind of crystal growth composite crucible.

Background technology

In the sapphire crystal growth system, crucible is vital parts, and the sapphire starting material after the heat fused, carry out sapphire crystal growth under the guiding of seed crystal in crucible; Because slowly carry out sapphire crystal growth (more than 2000 ℃), long-time (more than 10 days) under hot environment, therefore, require crucible can be high temperature resistant, long lifetime, low cost; Because the liquid sapphire raw material after the fusing is in the middle and lower part of crucible, thus tend to cause the crucible middle and lower part to occur loss, cracking, disrepair phenomenon more easily, thus cause whole crucible to scrap.Crucible of the prior art is the cylindrical crucible structure, in the sapphire crystal growth process, will cause integral body to scrap in case the crucible middle and lower part is damaged, thereby increase production cost.

Summary of the invention

The purpose of the utility model provides a kind of crystal growth composite crucible, has solved cylindrical crucible structure of the prior art, because loss, cracking, disrepair phenomenon appear in the crucible middle and lower part, thus the problem that causes whole crucible to scrap.

The technical scheme that the utility model adopted is, a kind of crystal growth composite crucible is made up of crucible main body and lengthening crucible tube, and crucible main body and lengthening crucible tube are through locating the mating surface socket;

Described location mating surface mode is that the inner convex platform of lengthening crucible tube lower port and the outer lug boss socket of crucible main body upper edge constitute;

Perhaps, described location mating surface mode is that the inner convex platform of lengthening crucible tube lower port and the inner headed face socket of crucible main body upper edge constitute.

The beneficial effect of the utility model is, is set to composite structure up and down through crucible, and the crucible main body links together through location mating surface and lengthening crucible tube; The location mating surface is cylindrical surface or cone surface; The crucible main body realizes normal work-ing life, and the lengthening crucible tube can be repeatedly used, thereby reduces production costs the comprehensive work-ing life of improving crucible; Simple in structure, easy to manufacture, easy to use.

Fig. 2 is the view after raw material melts in the utility model crucible embodiment 1 working process;

Fig. 3 is the socket mode structural representation of the utility model crucible embodiment 2 when wall thickness is thin.

Among the figure, 1. the crucible main body is 2. located mating surface, 3. lengthening crucible tube, 4. solid feed, 5. liquid raw material.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.

As shown in Figure 1, the structure of the utility model composite crucible is, is made up of crucible main body 1 and lengthening crucible tube 3, and crucible main body 1 is consistent with the material of the crucible tube 3 that extends; Crucible main body 1 links together through location mating surface 2 sockets with lengthening crucible tube 3.

Location mating surface 2 is the cylindrical surface socket, and location mating surface 2 can also be the cone surface socket.

With reference to Fig. 1, Fig. 2, for the thicker crucible of wall thickness,, constitute location mating surface 2 by inner convex platform, outer lug boss through the inner convex platform of lengthening crucible tube 3 lower port and the outer lug boss socket of crucible main body 1 upper edge, realize socket.

With reference to Fig. 3, for the thin crucible of wall thickness,, constitute location mating surface 2 by inner convex platform, inner headed face through the inner convex platform of lengthening crucible tube 3 lower port and the direct socket of inner headed face of crucible main body 1 upper edge, realize socket.

The utility model composite crucible is loaded into solid feed the upper edge height of lengthening crucible tube 3 earlier, then in the course of the work; Along with the continuous thawing of raw material, be in when the real solution plane after whole thawings within the splendid attire capacity of crucible main body 1, crucible main body 1 is born bigger working load; When loss, cracking, disrepair phenomenon appear in the crucible main body; Can normally change, realize normal work-ing life, the lengthening crucible tube then can be repeatedly used; Significantly lowered the replacement cycle of lengthening crucible tube, the effect that reduces cost is obvious.

The composite crucible of the utility model, simple in structure, easy to manufacture, easy to use, can be widely used in sapphire crystal growth system, solar energy silicon single crystal growing system, laser crystal growth system and other high temperature crystal growth system.
