Specific implementation mode
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in detail.
A kind of purification sublimation apparatus, including sequentially connected distillation furnace body 001, vacuum transition chamber 002, electrostatic precipitation formula
Vacuum pump protective device 003 and vacuum pump 005 connect the vacuum pump protective device of electrostatic precipitation after vacuum transition chamber 002
003, vacuum pump 005 is connected by vacuum pipe 004.
The vacuum pump protective device 003 of electrostatic precipitation formula includes：
Discharge electrode 032；Charge is discharged, is attached on the dust of floating；
Collecting electrode 033；Release and the positive and negative opposite charge of the discharge electrode, adsorb dust.
Electrostatic precipitation may be used this field and be easier the discharge electrode 032 realized release negative electrical charge, and collecting electrode 033 discharges
Positive charge.
In order to more preferably adsorb dust, the workload of electrode is reduced, vacuum pump protective device 003 can also be in discharge electrode upstream
Filter layer 031 is set, and the filter layer carries out coarse filtration to the dust in air-flow, adsorbs the dust of bulky grain.Preferred institute
The filter layer 031 stated is set as netted.The collecting electrode 033 is set as plate.
The purification sublimation zone setting distillation furnace body 001.The distillation furnace body 001 is divided into quartz boat 010, high temperature
Area 011, collecting region 012, low-temperature space 013.
In sublimation process, coarse organic material is placed in quartz boat 010, vacuum pump 005 vacuumizes.Distil furnace body
001 heating organic material is flowed with the direction of vacuum pneumatic, some high temperature impurity can be deposited on high-temperature region 011, with temperature
Gradient reduce, target substance can be deposited on collecting region 012, some low temperature impurities can be deposited on low-temperature space 013.In this process
In, also the dust of some low temperature impurities i.e. organic material will not be deposited on low-temperature space 013, it will as vacuum pneumatic passes through
The vacuum pump protective device 003 of electrostatic precipitation formula is crossed, organic material dust first passes through the coarse filtration net coarse filtration of filter layer 031,
