Description
Technical field
The utility model relates to purifying plants, and in particular to a kind of vacuum rotating sublimation purification device.
Background technique
Conventional sublimation purification device, usually material are placed in distillation boat, and raw China's boat is closed at one end, other end setting
Height is the baffle of caliber 1/3, places aggregate pipe after the boat that distils, and the material solidification of gasification state, distillation boat, collection are made using thermal gradient
Expects pipe is static.Material receives heat by two modes, first is that material bottom cambered surface contact quartz ampoule absorb heat and bottom cambered surface by
Infrared radiation absorbs heat, second is that plane is by infrared radiation absorption heat on material.The upper plane of only material is gasification
Face, gasification rate are limited by the gasification face of material.Material vaporized molecules are spread from high density to low-density direction, pass through heat
Heat solidification is discharged when gradient paths, the solidification amount for bottom of the tube of gathering materials is larger, and the more other places of bottom temp are high, solidifying front by
Gradual change is small.Since pneumatization of the material in distillation boat is limited, so seriously affecting the speed and efficiency of material sublimation purification.
Utility model content
In view of the deficiencies of the prior art, the utility model discloses a kind of vacuum rotating sublimation purification devices.
The technical solution of the utility model is as follows:
A kind of vacuum rotating sublimation purification device, including vitreosil tube chamber；It is installed in the vitreosil tube chamber
There is middle layer quartz ampoule；The middle layer quartz ampoule is equipped with rotary drive mechanism；Rotary drive mechanism drives the rotation of middle layer quartz ampoule；
Further include vacuum pump group, is connected to vitreosil tube chamber one end；It further include upper warm area heating module and lower warm area heating module；
The upper warm area heating module and the merging of lower warm area heating module are wrapped in except the vitreosil tube chamber；To sublimator material
It is placed within the quartz ampoule of middle layer.
Its further technical solution be further include support construction；The support construction supports the middle layer quartz ampoule
Within vitreosil tube chamber.
Its further technical solution is that the rotary drive mechanism has multiple.
Its further technical solution is, the direction of rotation of the rotary drive mechanism be rotate in the forward direction, counter-rotating；Institute
The rotation angle for stating rotary drive mechanism is 0 °~360 °.
The advantageous effects of the utility model are:
In the present invention, middle layer quartz ampoule is increased in furnace chamber, middle layer quartz ampoule is connected to rotary drive mechanism,
To drive middle layer quartz ampoule axially to rotate.In this way, sublimator material rotary motion during heating is driven, the material with mobile phase
Expect melted by heat, be uniformly adhered in distillation boat inner wall, increases material gasification face, when same material solidification, equably solidify
In the inside pipe wall that gathers materials of rotation, material solidification face is increased.Accelerate distillation, setting rate, distillation, coagulum are heated evenly,
Environment thermal field is uniform, and product gradient is apparent.In addition rotation process can also be eliminated because quartz refraction is irregular, the heating source temperature difference, control
Thermal field caused by the factors such as component error is uneven.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model.
Specific embodiment
Fig. 1 is the structure chart of the utility model, as shown in Figure 1, the utility model includes vitreosil tube chamber 1.Vacuum
Middle layer quartz ampoule 2 is installed in quartzy tube chamber 1.Middle layer quartz ampoule 2 is equipped with rotary drive mechanism 3.3 band of rotary drive mechanism
Dynamic middle layer quartz ampoule 2 rotates.Rotary drive mechanism 3 can have one or more, and multiple rotary drive mechanisms can increase rotation
Rotatory force.Rotary drive mechanism 3 can be axial direction electric machine etc..The direction of rotation of rotary drive mechanism 3 is to rotate in the forward direction, inversely revolve
Turn.The rotation angle of rotary drive mechanism 3 is 0 °~360 °.So rotary drive mechanism 3 can be rotated with 360 °, or with any
The rotation of angle and direction.
Further include vacuum pump group 6,1 one end of vitreosil tube chamber is connected to by vacuum exhaust pipe.Vacuum pump group 6 works
When, constantly by vacuum pumping state in vitreosil tube chamber.It further include upper warm area heating module 4 and lower warm area heating module 5.
The directly-managed tube chamber 1 of vacuum is cylindrical shape, and upper warm area heating module 4 and lower warm area heating module 5 are merged into lower section above
One big cylinder body cavity, is wrapped in except vitreosil tube chamber 1.It is placed within middle layer quartz ampoule 2 to sublimator material.
It further include support construction 7.Middle layer quartz ampoule 2 is supported within vitreosil tube chamber 1 by support construction 7, still
Rotational action of the middle layer quartz ampoule 2 in vitreosil tube chamber 1 is not influenced.
At work, rotary drive mechanism 3 rotate, drive middle layer quartz ampoule 2 rotate, drive middle layer quartz ampoule 2 in
Sublimator material rotation.To sublimator material in rotation, due to the rotation speed of middle layer quartz ampoule 2, a part can be adhered in middle level
On the inner wall of quartz ampoule 2, then the surface area with sublimator material exposure greatly improves, and can improve distillation efficiency.Again due in this way
Rotation mode can guarantee that sublimator material has certain surface area and material is heated evenly, it is possible to it is appropriate reduce plus
The heating temperature of thermal modules can also have same distillation effect, then reduce the heated decomposing phenomenon of material itself, improve
The purity of material.
The above are merely preferred embodiments of the present invention, and the utility model is not limited to above embodiments.It can manage
Solution, those skilled in the art do not depart from the utility model spirit and design under the premise of directly export or associate other
Improvements and changes are considered as being included within the scope of protection of this utility model.
