SYSTEM FOR AUTOMATIC RAW MATERIAL SUPPLY TO ELECTROLYSERS WITH SELF-BAKING ANODES Russian patent published in 2015 - IPC C25C3/14 

FIELD: electricity.

SUBSTANCE: system includes the main aeroflow conveyor, a hopper of an alumina point feeder (APF) module, an air supply system containing high-pressure radial fans, gate valves and a header of the associated pipeline. Alumina is supplied to hoppers of the APF module by means of a distributing aeration pipe made from high-strength material with tightly installed discharge branch pipes and consisting of an aerating pipe, an acceleration section and a conveying section or sections, and air injection through the associated pipeline to forced-draft cavities of the main aeroflow conveyor and the aerating pipe is performed by means of the air supply system containing at least two high-pressure fans, and the header of the associated pipeline is provided with an automatically controlled turning gate valves.

EFFECT: improved reliability of automatic supply and absence of dusting and losses of raw material.
