Abstract
The utility model discloses a kind of suspension type guide shell, comprise urceolus, inner core and intermediate course, the upper flange of inner core is overlapped on the upper flange of urceolus, it is characterized in that: be provided with the projection in multiple horizontal directions with the inner core bottom of the vertical junction of urceolus bottom, with the urceolus bottom of projection corresponding position on be provided with the groove matching with projection.Adopt the utility model scheme, together with guide shell inner core snaps over mutually with guide shell urceolus, make also can not produce after fracture at guide shell urceolus the phenomenon of falling in quartz crucible.
Description
Technical field
The utility model relates to the suspension type guide shell in a kind of solar monocrystalline silicon manufacture field.
Background technology
In solar monocrystalline silicon manufacture field, single crystal growing furnace is indispensable production unit.Graphite guide shell is as parts in the hot system of single crystal growing furnace, in single crystal growth process, play vital effect, it can dredge argon gas, impels it to flow to fixing direction, carry the latent heat producing in crystal pulling process, ensure monocrystalline crystalline growth smoothly.The structure of existing guide shell as shown in Figure 1,, and is directly subject to the baking of high temperature by guide shell frame on silicon solution, and the time has been grown, and is easy to be corroded by silicon steam, causes the fracture of guide shell urceolus, falls in quartz crucible, causes the generation of stewing stove accident.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of guide shell urceolus suspension type guide shell dropping that ruptures that prevents.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of suspension type guide shell, comprise urceolus, inner core and intermediate course, the upper flange of inner core is overlapped on the upper flange of urceolus, it is characterized in that: be provided with the projection in multiple horizontal directions with the inner core bottom of the vertical junction of urceolus bottom, with the urceolus bottom of projection corresponding position on be provided with the groove matching with projection.
Wherein, the upper surface of described projection is scarp upwards, and the angle of scarp and horizontal plane is 30 degree.
Wherein, described projection is 3 or 4.
Owing to having adopted technique scheme, the obtained technical progress of the utility model is:
1, adopt the utility model scheme, together with guide shell inner core snaps over mutually with guide shell urceolus, make also can not produce after fracture at guide shell urceolus the phenomenon of falling in quartz crucible.
2, the upper surface of projection is scarp upwards, has ensured the castering action of guide shell inner core to the landing of guide shell urceolus.
3, projection is 3 or 4, is convenient to the installation of guide shell inner core and guide shell urceolus.
Brief description of the drawings
Fig. 1 is the structural representation of existing guide shell.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is outer tube structure schematic diagram of the present utility model.
Fig. 4 is inner tube structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing 2 to Fig. 4 and specific embodiment, the utility model is described in further detail.
A kind of suspension type guide shell, comprise urceolus 1, inner core 2 and intermediate course 3, the upper flange of inner core is overlapped on the upper flange of urceolus, be provided with the projection in multiple horizontal directions with the inner core bottom of the vertical junction of urceolus bottom, with the urceolus bottom of projection corresponding position on be provided with the groove matching with projection, the upper surface of described projection is scarp upwards.In embodiment, the angle of scarp and horizontal plane is 30 degree, and described projection is 3 or 4.
In embodiment, guide shell inner core bottom makes 4 projections, and angle is at 30 degree, width is at 9mm, and guide shell urceolus is made 4 grooves, positions involutory with 4 projections of inner core, and its surrounding is increased and extends edge, width, at 9mm, is just being used on last rotation location, so, if once guide shell urceolus goes wrong, will be with inner core mutually in interlock, stop urceolus to be fallen in quartz crucible, avoid the generation of accident.
