Accompanying drawing is the structural representation of the utility model.
Among the figure: 1. decompression distillation jar, 2. receiving tank, 3. cooling tube, 4. netted demister, 5. heating jacket; 6. charge door, 7. drain hole, the 8. vertical condenser of tubulation, 10. flow guiding attachment, 11. cold wells; 12. dust filter unit, 13. vavuum pumps, 14. mercury gages, 15. vacuum meters; 16. temperature-measuring port, 17. top temperature-measuring ports, 18. right side temperature-measuring ports, 24. post-condensers.
The specific embodiment
Referring to accompanying drawing; The utility model has adopted two isometric(al) tank bodies---decompression distillation jar 1 and receiving tank 2; In these two tank body outsides heating and heat-insulating device is installed; Condenser 8 adopts the vertical condenser of biserial pipe, and is furnished with flow guiding attachment 10, in vacuum system, has increased cold well 11 and dust filter unit 12.Its operation principle is: the liquid aluminium alkoxide receives temperature and vacuum pressure acting in conjunction in decompression distillation jar 1, and the overwhelming majority is evaporated and becomes the gaseous aluminum alkoxide, and what be not evaporated is impurity, still stays in the decompression distillation jar 1; Highly purified gaseous aluminum alkoxide is extracted in the shell and tube condenser 8 by vavuum pump 13, be cooled to the liquid aluminium alkoxide after, collect in the receiving tank 2, thereby realized the purification process of aluminium-alcohol salt.Adopt cold well 11 and dust filter unit 12 can prevent that the small amount of solid state aluminium-alcohol salt from getting in the vavuum pump 13.Cross the solid defective of condensation because the utility model has overcome in the existing vacuum distillation apparatus, thus realized the aluminium-alcohol salt vacuum distillation apparatus continuously, stable, carry out efficiently.The horizontal condenser that the utility model also will have use now changes vertical pipe bundle condenser into, can effectively prevent the curing of liquid aluminium alkoxide in condenser.
Vacuum distillation apparatus is made up of decompression distillation jar 1, receiving tank 2, condenser 8, condenser 9, cold well 11, dust filter unit 12, vavuum pump 13, post-condenser 24.Around the decompression distillation jar 1 heating jacket 5 is housed, the front side has charge door 6, bottom to have drain hole 7, upper left-hand to have temperature-measuring port 16, top to link to each other with cooling tube 3, is equipped with in the cooling tube 3 that netted demister 4, side are equipped with mercury gage 14, temperature-measuring port 17 is equipped with at the top.Receiving tank 2 is equipped with heating jacket 26 on every side, the bottom has drain hole 25, upper right to have temperature-measuring port 18, the left and right sides, top that the vertical condenser 8 of tubulation is housed respectively.Decompression distillation jar 1 equates with the volume of receiving tank 2, and the bottom of condenser 8 has that flow guiding attachment 10 extend in the receiving tank 2, top links to each other with cooling tube 3 on the decompression distillation jar 1 through pipeline.Condenser 9 links to each other with cold well 11 through pipeline, vacuum meter 15 is arranged on the cold well 11, also be connected with dust filter unit 12 through pipeline 21, and vavuum pump 13 is connected with dust filter unit 12 through pipeline, is connected with post-condenser 24 through pipeline.
During work; Liquid aluminium isopropoxide is joined in the decompression distillation jar 1 by charge door 6; Heat with 5 pairs of decompression distillation jars 1 of heating jacket, when temperature and vacuum reached rated value, liquid aluminium isopropoxide was vaporized into steam and gets into cooling tube 3; Enter into condenser 8 through netted demister 4 with pipeline 19, most steam are condensed into liquid aluminium isopropoxide and are imported in the receiving tank 2 by flow guiding attachment 10.Remaining steam through condenser 9 again condensing reflux in receiving tank 2; Minute quantity steam through pipeline get into cold well 11, again after pipeline 21 gets into dust filter units 12 and removes solids; Get into vavuum pump 13 through pipeline again, after pipeline gets into post-condenser 24 liquefies.When the utility model is worked; Can monitor the temperature in decompression distillation jar 1, cooling tube 3 and the receiving tank 2 respectively through temperature-measuring port 16, temperature-measuring port 17 and temperature-measuring port 18 at any time; Monitor the pressure in cooling tube 3 and the cold well 11 respectively through mercury gage 14 and vacuum meter 15, so that still-process is adjusted.
