UNIT FOR TRANSPORTING GRANULAR MATERIAL IN FLUIDISED STATE (VERSIONS) Russian patent published in 2008 - IPC B65G53/20 

FIELD: technological processes.

SUBSTANCE: invention pertains to non-ferrous metallurgy and specifically to transportation of granular material in fluidised state according to requirements and can be used in electrolytic production of aluminium for transportation of alumina from the collecting bin to feed bins. The unit consists of a collector bin (1), equipped with an off-loading cone (2), joined by an air slide conveyor (3) to not less than one single type loading module (6), consisting of transport and feed air slide conveyors (8). The unit is equipped with a unified system of supplying aerating gas, including a unified pneumatic track with gas outlet connection pipes, with a valve system. In the first alternative there is unit with a unified pneumatic gas outlet connection pipe joined to the first in the direction of putting alumina in the section of the feed air slide conveyor. In the second alternative, the unit is made such that, each section of the feed air slide conveyor is joined to the unified pneumatic gas outlet connection pipe. The invention provides for high cost effectiveness, high degree of reliability, working efficiency and reparability, as well as flexible operational control of the process of transporting granular material with minimum energy losses and low consumption of the aerating gas.

EFFECT: flexible operational control of the process of transporting granular material with minimum energy losses and low consumption of the aerating gas, increased cost effectiveness, reliability and reparability of the process.
