Publication number: 20240113308Abstract: An electrodeposition installation with active intercell bars that has at least three cells connected or capable of being connected in series between the positive pole and the negative pole of a rectifier is disclosed. Several active intercell bars installed between the cells and at the ends of the installation, each having a common conductive body with multiple busbar segments, one for each electrode electrically insulated, but independently electrically connectable to the common conductive body or to an extension cable by switches controlled from a microcomputer with remote communication capacity. The invention affords the advantage of providing a conventional plant with secure protection of electrodes against short circuits with complete management of production by complete monitoring of the process in real time, and with a greater production capacity by the internal depolarisation of the electrodes.Type: ApplicationFiled: September 28, 2020Publication date: April 4, 2024Inventor: Felix PRADO PUEO

Patent number: 9422632Abstract: The present invention relates to a device for the continuous monitoring of current distribution in the cathodes and anodes of an electrolyzer comprised of at least two adjacent electrolytic cells, each containing a multiplicity of said cathodes and anodes. The device according to the invention is composed essentially of at least one current-collecting bus-bar having housings suitable for supporting the electrodes and a base of insulating material whereon the bus-bar abuts. The base has integrated probes for measuring voltage. The invention also relates to a permanent monitoring system allowing to evaluate in continuous current distribution on each electrode in cells used in particular in metal electrowinning or electrorefining. The invention also relates to a method for retrofitting of an electrolyzer comprising the replacement of an existing insulating base with a new base element having integrated probes for measuring voltage.Type: GrantFiled: February 20, 2014Date of Patent: August 23, 2016Assignee: INDUSTRIE DE NORA S.P.A.Inventor: Felix Prado
