Abstract: The invention refers to an air supply system (1) for a group of cells (4) arranged for dosing the individual air demand of each electrolytic cell (2) that must be fed to its electrolyte through a system of controlled air diffusion. It comprises a low pressure blower (5), a central feed pipe (6) and a plurality of feed branches (7); a flow meter (8) and a flow regulator (9) are associated to each feed branch. The assembly is connected to a bent hose (12) arranged on the walls of said electrolytic cell (2) to allow connection with an isobaric ring (3), so that the fed air can be diffused homogeneously and sustainedly in time to the electrolyte through selectively perforated hoses (16). The present invention also refers to the process of installation, calibration and operation of the air supply system.

Abstract: The invention provides a self supporting isobaric structure for electrolyte aeration in an electrodeposition cell for electrolytic refining or winning of non-ferrous metals, and a method of fabrication thereof. The structure is constructed using thermoplastic material pipes the external surface of which is wrapped in a thermosetting polymer composite material and one or more successive wrapped layers of fiber glass mats, thus forming a structural monoblock. The pipes are arranged in a reticular layout having a generally rectangular frame that follows the contour of the cell, transverse structural elements that connect the longer sides of the frame and tubular elements connecting the shorter sides of the rectangular frame. The tubular element provide a means for gas diffusion and aeration in the cell. Furthermore, the invention provides pipe couplings that allow shorter elements to be connected together in order to achieve the reticular configuration.
