Please refer to Fig.1-2, a kind of vacuum grinds dryer, including stirring cylinder 8, vacuum extractor and heater 1, stirring
8 side of cylinder offers feed inlet and outlet 3 and is equipped with cover board 2 at feed inlet and outlet 3, stirs and is placed with glass hard steel inside cylinder 8
Ball 11, the steel ball 11 placed in stirring cylinder 8 can be various specifications, and cylinder 8 is rotatable is erected on outer framework for stirring,
The one end for stirring cylinder 8 is sealed end, and sealed end passes through driving motor by the axis connection of transmission gear 6 and driving motor
The stirring rotation grinding of cylinder 8 is driven, generates after centrifugal force takes steel ball 11 to certain altitude and falls when stirring cylinder 8 and rotating,
To generate bang and abrasive action to material, the other end of stirring cylinder 8 is connected to by hose with vacuum extractor, is taken out true
Empty device can make 8 inside of stirring cylinder keep suitable vacuum degree, make inside to being vacuumized inside stirring cylinder 8
Material will not be deliquesced and be aoxidized, heater 1 be located at stirring cylinder 8 lower section, if agitation grinding during need to material into
Row heating, drying can be realized by heater 1.
Preferably, heater 1 is semicircular in shape in the present embodiment, and semicircular heater 1 will stir cylinder 8 half and wrap
It encloses, it can be to the heating, drying of material evenly.
Further, a temperature probe 10, temperature probe 10 and temperature are there also is provided at heater 1 on outer framework
Control unit connection is spent, which is that a thermal resistance can be according to setting during grinding stirring to material
Good temperature is dried to the energization of heater 1.
Further, sealed end is provided with Pirani gauge 5, and Pirani gauge 5 is connect with compound vacuum gauge, and Pirani gauge 5 can will stir
The vacuum degree mixed in cylinder 8 is transmitted to compound vacuum gauge, and when reaching required vacuum degree, startup driving motor, which is ground, to be stirred
It mixes.
