LABORATORY APPARATUS FOR ANALYSING ANODE PROCESSES OF AN ALUMINUM ELECTROLYSIS CELL Russian patent published in 2019 - IPC C25C3/20 

Abstract RU 2700904 C1

FIELD: monitoring and measuring equipment.

SUBSTANCE: invention relates to a laboratory apparatus for analysing anode processes of an aluminum electrolytic cell. Plant comprises shaft electric furnace, two electrolysis cells with analysed electrolyte, placed in steel retort with graphite powder, which are graphite crucibles with bottom plates placed in bottom, immersed in electrolyte with analysed anode, thermocouple and aluminum comparison electrode, a direct current source, ammeters and voltmeters for measuring current and voltage in each cell, an additional cell installed in the retort and containing a reference electrolyte and a reference anode, wherein reference electrolyte consists of cryolite-alumina melt with cryolite ratio of 2.1–3.0, concentration of calcium fluoride 0.0–8.0 wt%, alumina – 0.5–12.0 wt% rest is cryolite, and the analysed electrolyte additionally contains contaminant.

EFFECT: enabling expansion of technological capabilities of installation of studying anode processes and studying in laboratory conditions of reasons and mechanisms of violations of anode processes of aluminum electrolysis cells.
