Be furnished with an annular calandria 5 bottom body of heater 3, sidewall of the furnace body periphery equi-spaced apart is furnished with four calandrias 5, and described calandria can adopt resistance heated, induction coil to heat or the mode such as heating using microwave.
With temperature sensor on each calandria 5, controller gathers the temperature signal of each temperature sensor and controls the heating-up temperature of each calandria.
Described body of heater 3 is supported in the middle of bottom vacuum chamber 1 by support spring 6, is fixed with mount pad 7 in the welded top of described support spring 6, and this mount pad 7 is connected with the threaded mounting hole of body of heater 3 bottom centre by the nipple on its top.
Be equipped with in the other stationary cloth of body of heater 3 electromagnet 8 being controlled unlatching by controller, when electromagnet is opened, body of heater 3 is adsorbed to electromagnet side, and now electromagnet disconnects, and be subject to the effect of bottom support spring 6, body of heater 3 can rock back and forth.
Directly over described body of heater 3, be furnished with the induction fan 11 of a temperature sensor 10 and adjustable speed by mounting bracket 9, the lower end of this mounting bracket 9 is dismountable to be arranged on body of heater.
Temperature sensor 10 above body of heater 3 and induction fan 11 are arranged on the top nose of mounting bracket 9 along the center line of body of heater 3, and this temperature sensor 10 is positioned at the below of induction fan 11.
Above-mentioned each temperature sensor in the present embodiment can adopt PT100 type temperature sensor.
Above-mentioned vacuum heater in use, first raw material (as macromolecular material, crystalline material, mineral aggregate etc.) is put into crucible, again crucible is put into body of heater, being spun by body of heater 3 is fixed on the mount pad 7 of support spring 6, again mounting bracket 9 is in place, vacuum chamber is evacuated to vacuum state by vavuum pump 2, then sets technological temperature and time on the controller according to the characteristic of raw material.In heating process, the temperature of each temperature sensor of controller Real-Time Monitoring, when occurring that heating-up temperature difference is larger, the blas (being realized by mcu programming) of controller regulates the heating-up temperature of some calandrias on body of heater 3, makes heating-up temperature even.In heating process, electromagnet 8 is controlled by the controller and periodically disconnects, and crucible ceaselessly rocks with body of heater, raw material is evenly distributed in crucible, and avoid amount of localized heat in raw material to concentrate, rock the effect also played heat radiation and stir raw material in addition, make raw material thermally equivalent.
After homogeneous heating a period of time, when heated material arrival distillation is temperature required, vapor stream can be produced, when vapor stream arrives the temperature sensor 10 be arranged in above crucible, this temperature sensor is by the vapor stream temperature feedback that detects to controller, and the rotating speed of controller adjustment induction fan 11, to control the vapor stream rate of climb and temperature, avoid hot gas to assemble on crucible top, under induction fan effect, gaseous matter is just upwards plated on substrate.
Embodiment two:
See Fig. 3, in the present embodiment, in vacuum chamber, be centrally arranged symmetrically with two cover bodies of heater 3, in each body of heater, be provided with the silica crucible for placing raw material, vacuum chamber center of top being provided with substrate 4.
