DEVICE FOR FEEDING OF BULK MATERIALS INTO ELECTROLYTIC CELL WITH BURNT ANODES Russian patent published in 2009 - IPC C25C3/14 

FIELD: metallurgy.

SUBSTANCE: invention relates to receiving of aluminium on electrolytic cells with top current contact jaw with self-burnt anodes. Device for feeding of alumina into electrolytic cell contains bin, fixed to anodic casing of electrolytic cell with clearance and outfitted by box, fixed to bottom part of bin, punch of electrolytic shell with rod and drive, and guideline bushing of bin. Back wall of bin is outfitted by protective screen. On rod there are installed set of brushes, implemented from helical wire and separated by spacing collar on top and bottom parts. Height of set of brushes in top part more than running of rod, diametre of brushes set from helical wire is more than diametre of guideline bushing of bin. Over spacing collar it is installed self-centering sleeve, allowing chamfers and windows in its bottom part. Rod is connected to pointer by means of plug-type connection and with ability of rigid connection of brushes set and spacing collar on rod. On back wall of bin it is installed additional collapsible screen. For ability of volume regulation of raw material dose diametre and height of spacing collar on rod and guideline bushing of bin are implemented with correlation 1: (0.4-0.6).

EFFECT: there is provided high reliability of device operation and reduction of falling of side surface of anode in places of connection of bin to anode shell.
