A fluorine-containing aluminum oxide secondary circulation shunt device

Abstract

The utility model discloses a kind of fluorine-carrying aluminium oxide secondary circulation shunt devices, belong to aluminium electrolysis dry purification equipment technical field, including boiling bed, circulation discharge opening is provided on boiling bed, adjustable position is provided on boiling bed and shunt plate, circulation material passage is formed between shunt plate and the right side wall of boiling bed, fluorine-carrying material passage is formed between shunt plate and the left side wall of boiling bed, buffering baffle is provided on boiling bed, circulation discharge opening is communicated with distributor by conveying pipeline, fluorine-carrying material passage is communicated with pneumatic elevator.The utility model can be realized by adjusting shunt plate position, proportionally split fluorine-carrying aluminium oxide in boiling bed into two parts;Splitting ratio is determined by the position of shunt plate, can be proportionally shunted according to production needs, accurately control fluorine-carrying aluminium oxide material amount participating in secondary circulation, realize secondary circulation material accurate feeding, effectively control the physical property of fluorine-carrying aluminium oxide, to meet production needs, reduce the influence on electrolytic production.
