Microporous or perforated hoses Hose system used for Bubbling air or gas to the electrolyte in a cell for production of metal, which comprises a multiplicity of perforated Hoses and Valves; the System Operation procedure

摘要

The punched pipes or microporous hoses used to bubble air located on the floor of the electrolytic cells for metals production are exposed to breakage or physical damages by the accidental fall of anodes, cathodes on them or by the premature release of part of the cathode deposition as well as by damages produced by intervention inside the cells. Said damages force to at least stop the air bubbling, damaging the quality of the metal produced to stop the production process for its repair with the consequent loss of production. The valves system of this invention located at the entrance of the front and rear air distributors as well as in both ends of each of the punched pipes or microporous hoses, allows the insulation of each of these pipes or hoses from the system and do continue the air bubbling even in the case of damage or breakage of one or more of them, making the production without air bubbling less frequent as well as the downtime of the operation to repair the damages, thereby decreasing the production losses. The operation procedure starts with the identification of the air injection line that failed, followed by the closing of the front and rear valves of said line, then with the visual inspection to check that the size and uniformity of the bubble is restored.
