Description
Technical field
The utility model relates to the long brilliant stove of a kind of sapphire, the long brilliant stove of especially a kind of heat-exchanging method sapphire.
Background technology
The structure of the long brilliant stove of existing heat-exchanging method sapphire as shown in Figure 1, the heat transfer tube of its heat-exchanger rig is to fix at the charging line position that advances, and is in relative static conditions in body of heater afterwards always.
The deficiency of the long brilliant stove of this structure sapphire has:
1, after heat-exchanger rig is fixing, refills crucible, need accurately modulation to support the support ring of crucible, overlap with the central position of heat-exchanger rig with the central position of guaranteeing crucible, adjusting simultaneously crucible is horizontal, two purposes so both be difficult to reach simultaneously, spended time directly has influence on production efficiency very much again;
2, behind the crucible elder generation fixed position, loading under the large weight raw material condition, owing to easily making the heat exchanger distortion under the action of gravity, also may cause deflection and the displacement of seed crystal in the crucible, affecting the work-ing life of crystal mass and heat exchanger.
Summary of the invention
For solving above-mentioned the deficiencies in the prior art, the utility model provides a kind of can adapt to the load-carrying of Different Weight to the long brilliant stove of the adaptive sapphire of load-carrying, can remain complete and stable with the crucible relative position of the profile of heat transfer tube.
Concrete technical scheme of the present utility model is:
The long brilliant stove of a kind of self-adaptation sapphire comprises
Body of heater comprises the encloses container of bell and body of heater base plate;
Crucible is for the container of sapphire crystal growth;
The attemperator that arranges around the crucible periphery in the attemperator, body of heater is used for keeping the crucible thermal field;
Heating unit is for the device that sapphire growth institute heat requirement is provided;
Heat-exchanger rig, the compressor that comprises bracket, the heat transfer tube that links to each other with bracket of being located at crucible bottom and heat-eliminating medium circulation in the heat transfer tube is provided, heat exchange pipe furnace distributed outside has cutting ferrule mechanism, and heat transfer tube is fixedly connected with the body of heater base plate by this cutting ferrule mechanism;
It is characterized in that being provided with one section airtight elastic telescopic corrugated tube between the ferrule fitting of described cutting ferrule mechanism and the body of heater base plate.
Optimally, an end of described elastic telescopic corrugated tube is provided with the contiguous block for airtight affixed ferrule fitting, and the other end is provided with the flange for airtight connection body of heater base plate.
Optimally, be provided with the annular groove that holds cutting ferrule bottom the described contiguous block.
Optimally, described flange and contiguous block are furnished with gasket seal.
Corrugated tube is a kind of pressure measurement elastic element in the pressure measuring instruments, and it has the housing of the cylinder-shaped thin wall wrinkle of a plurality of transverse waves.Corrugated tube has elasticity, can produce displacement under pressure, axial force, transverse force or Moment.
Corrugated tube is widely used in instrument, and main application is the measuring sensor as pressure measuring instruments, converts pressure to displacement or power.The corrugated tube tube wall is thinner, and sensitivity is higher, and useful range is that tens of handkerchiefs are to tens of MPas.In addition, corrugated tube also can be used as the seal isolation element, two media is separated or prevented the measure portion of harmful fluids access arrangement.It can also be used as shim member, utilizes the temperature error of the mutability compensation apparatus of its volume.Sometimes also be used as the resilient connection joint of two parts etc.Corrugated tube can be divided into two kinds of metallic bellows, nonmetal corrugated tubes by constituent material; Can be divided into individual layer and multilayer by structure.Singel-ply bellows (seeing figure) is used more.Multiply bellows intensity is high, good endurance, and stress is little, is used in the important measurement.The material of corrugated tube is generally your alloy of bronze, brass, stainless steel, Monel metal and inconel etc.
In the utility model, the effect of corrugated tube is the load-bearing buffering of heat exchanger tube.The long brilliant stove of heat-exchanging method sapphire be that the load-bearing snubber assembly of routine is unapproachable, and corrugated tube has good stopping property and ductibility, can satisfy simultaneously stopping property and two requirements of buffering owing to there being the stopping property requirement.
The long brilliant stove of the utility model sapphire, under the state of heat-exchanger rig non-locking, begin charging, be under the free state at heat-exchanger rig under the action of gravity of raw material, can be in lower free movement, avoid causing the heat-exchanger rig mechanical destruction because of the gravity than heavier feedstocks more than the 200kg, also can avoid heat-exchanger rig that the reactive force of crucible is changed seed crystal direction or position in the crucible, the minor alteration of seed crystal direction or position can cause a lot of lattice defects such as twin, crystal boundary, dislocation, bubble etc.; After finishing whole raw materials and loading, heat-exchanger rig fixed and the good contact of assurance and crucible bottom, thereby in order in crystal growing process, enough heats are taken away and set up suitable thermograde, finish the growth of crystal.
The long brilliant stove of the utility model sapphire both can bear larger weight, realized the growth of large weight crystal, prolonged again the work-ing life of heat-exchanger rig, had solved the problem of loading than heavier feedstocks more than 200 kilograms.
