Description
Technical field
The utility model relates to silicon single crystal technical field of crystal growth, and in particular to a kind of thermal field of single crystal furnace axis heat preservation knot
Structure is mainly used for solving the problems, such as on thermal field of single crystal furnace that heat leakage causes power to increase.
Background technique
Traditional straight pulling silicon single crystal furnace need to be done much after completing furnace raw material crystal pulling production to prepare the production of a new furnace
Many and diverse previous work, including blowing out it is cooling, wipe furnace, charge, vacuumize, the processes such as material.Entire technical process be all using
Electric energy is converted into thermal energy, because each production cycle inventory is more, drawing crystal is heavier, and unit source is smaller, and efficiency is also got over
It is high.Single crystal growth temperature is higher, and furnace wall is carried out using Steel material, usually leads to cooling water cooling, has just taken away graphite naturally
The heat that heater generates, since the crucible axis used needs to enter thermal field high-temperature area, so being also logical cooling on entire axis
Water, dispersed heat is larger from axis, since crystal for straight drawing monocrystal growth furnace comes into operation, have 93 years so far, but this
The situation of sample fails to be efficiently modified always.The heat loss of axis direction how is effectively reduced, gives associated production enterprise always
Bring serious puzzlement.
Utility model content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of thermal field of single crystal furnace axis insulation constructions, can subtract
The heat losses of few graphite axis direction.
Purpose of the utility model is realized as follows:
A kind of thermal field of single crystal furnace axis insulation construction, including heater, graphite crucible and graphite shaft, the graphite shaft setting exist
The center of furnace bottom, the upper end of the graphite shaft connect the crucible support of graphite crucible by axis support, and the lower end connection of the graphite shaft is not
It becomes rusty steel shaft, is socketed heat-retarding ring in the graphite shaft.
Preferably, the heat-retarding ring is cylindrical structure, is evenly equipped with multiple fixation holes on the heat-retarding ring.
Preferably, the inner wall of the heat-retarding ring is equipped with screw hole, is equipped in the graphite shaft and stainless steel shaft and screw hole
The screw thread to match.
Preferably, the heat-retarding ring is heat resisting and pressure resisting low heat transfer coefficient material.
Preferably, heat-retarding ring is carbon carbon composite.
Preferably, the upper surface of the furnace bottom is additionally provided with bottom insulating layer.
The beneficial effects of the utility model are:
The utility model structure is simple, and the heat in graphite shaft, which leads to cooling water by stainless steel shaft, to be taken away, and heat passes through
Heat-retarding ring brings biggish thermal resistance since heat transfer coefficient is lower, prevents heat from scattering and disappearing from stainless steel shaft, and then reach reduction
The purpose of heat loss, power needed for reducing heater.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein: heater 1；Graphite crucible 2；Crucible support 3；Axis support 4；Graphite shaft 5；Bottom insulating layer 6；Heat-retarding ring 7；Furnace bottom 8；

Specific embodiment
Referring to Fig. 1, the utility model relates to a kind of thermal field of single crystal furnace axis insulation constructions, including heater 1, graphite crucible 2
With graphite shaft 5, the center of furnace bottom 8 is arranged in the graphite shaft 5, and the upper end of the graphite shaft 5 connects graphite crucible by axis support 4
2 crucible support 3, the lower end of the graphite shaft 5 connect stainless steel shaft 9, are socketed heat-retarding ring 7 in the graphite shaft 5.
The heat-retarding ring 7 is cylindrical structure, is evenly equipped with multiple fixation holes on the heat-retarding ring 7.
The inner wall of the heat-retarding ring 7 is equipped with screw hole, is equipped with and screw hole phase in the graphite shaft 5 and stainless steel shaft 9
The screw thread matched.The heat-retarding ring 7 can be rotated with graphite shaft 5 and 9 synchronization lifting of stainless steel shaft, be reduced from stainless steel shaft 9 to graphite
The heat transfer of axis 5.
The heat-retarding ring 7 is heat resisting and pressure resisting low heat transfer coefficient material.Heat-retarding ring 7 selects carbon carbon composite, reduces heat
It takes away, reduces power consumption, can reduce by 10% overall power consumption.
The upper surface of the furnace bottom 8 is additionally provided with bottom insulating layer 6.It is further reduced the loss of heat.
Heat-retarding ring 7 is installed, graphite heating starts to generate heat when running, and heat passes through in graphite shaft 5 in single crystal growing furnace graphite shaft 5
Stainless steel shaft 9, which leads to cooling water, to be taken away, and heat passes through heat-retarding ring 7, and heat-retarding ring 7 is revolved with graphite shaft 5 and 9 synchronization lifting of stainless steel shaft
Turn, reduces from stainless steel shaft 9 to the heat transfer of graphite shaft 5 and bring biggish thermal resistance since heat transfer coefficient is lower, prevent heat
Amount is scattered and disappeared from stainless steel shaft, and then achievees the purpose that reduce heat loss, power needed for reducing heater.
In addition to the implementation, the utility model further includes having other embodiments, all to use equivalents or equivalent
The technical solution that alternative is formed, should all fall within the protection scope of the utility model claims.
