Embodiment Construction

[0029] The present invention provides a zinc electrolytic lead anode plate and a manufacturing method thereof. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] The zinc electrolytic lead anode plate provided by the invention is made by welding an anode plate surface and an anode beam, and the surface of the anode plate surface has a rough surface structure. The surface of the anode plate has a threaded, grooved or zigzag surface structure. Further, the size of the zigzag surface structure is: the tooth depth is 0-4mm, and the distance between the centers of adjacent teeth is 0-20mm. The groove shape is a circular groove shape or a grid shape groove shape.

[0031] Specifically, it can be as Fig...

Abstract

The invention discloses a zinc electrolytic lead anode plate and a manufacturing method thereof. The zinc electrolytic lead anode plate is formed by welding an anode plate surface and an anode beam, wherein the surface of the anode plate surface is of a rough surface structure. As the step of rerolling the anode plate surface by a second ST rolling mill is adopted, the rough surface structure is formed on the anode plate surface. The produced lead anode plate can be directly used without other processes when being used by manufacturers, so that the service life of the lead anode plate is prolonged. Moreover, the time of forming a stable protection layer by the lead anode plate in the electrolysis process is greatly shortened, the lead content in the separated zinc sheet is remarkably reduced, the zinc ingot quality is improved, and the electric energy unit consumption is reduced at the same time.

Description

technical field [0001] The invention relates to the field of zinc hydrometallurgy, in particular to a zinc electrolytic lead anode plate and a manufacturing method thereof. Background technique [0002] Anodes are an indispensable part of the electrolysis process in zinc hydrometallurgy. Since 2004, the output of zinc ingots in China has grown rapidly at a rate of 12% per year. By 2011, the production capacity of zinc ingots has reached 6 million tons, and the unit consumption of zinc anodes per ton is 0.15 According to calculations, about 900,000 new anode plates are needed in China every year. [0003] The lead anode used in the zinc electrolysis process is composed of an anode plate, a conductive rod, and an insulating sleeve. In the patent document (Application No. 201010547927.9), a pretreatment method for lead or lead alloy inert anodes for electrowinning zinc is disclosed, which includes steps: the composition of the pretreatment liquid: consisting of fluoride, sulfu...
