Wet-process discharge type ore pulp electrolytic lead device

Abstract

The invention discloses a wet-process discharge type ore pulp electrolytic lead device. An electrolytic membrane for containing ore pulp is arranged in an electrolytic tank body, and a stirring device is arranged in an electrolytic membrane cavity; the electrolytic membrane cavity is connected with the electrolytic tank body through an axial flow pump and a pipe; the electrolytic tank body is of a conic bottom structure, the conic bottom is provided with an axial stirring paddle and a spiral conveyor, and a knocking device is arranged outside the conic bottom; the conic bottom is connected with a temporary storage barrel through a collecting hopper, a discharging pump and a conveying pipe, a bib and a valve are arranged at the bottom of the temporary storage barrel, a filter net is arranged in the temporary storage barrel to be connected with a circulation pump, and an outlet of a pipe of the circulation pump is connected with the electrolytic membrane cavity. By means of the wet-process discharge type ore pulp electrolytic lead device, low-speed long-paddle large-area sweeping is adopted, so that coincident temperature density is achieved with low energy consumption; the knocking device and the spiral conveyor conduct synchronous and reasonable interruption starting, so that continuous tank bottom cleaning and sedimentation sponge lead discharging are achieved with low energy consumption; liquid circulation homogenization electrolysis is achieved through the axial flow pump and the pump, and the wet-process discharge type ore pulp electrolytic lead device is suitable for industrialization use and wide in prospect.

Description

technical field [0001] The invention relates to a wet discharge type pulp electrolytic lead device, which is especially suitable for electrolyzing pulp. Background technique [0002] The electrolytic cell is the key equipment supporting the electrolysis industry of lead, zinc, manganese, aluminum and other metals. However, most of the existing electrolytic cells can only electrolyze the solution, but not the electrolytic slurry. That is, the electrolytic solution must be prepared before electrolysis. . [0003] The preparation of mineral powder into electrolyte requires multiple steps such as compounding, dissolution, pressure filtration and impurity removal. The cost of many steps is high, and there is still a certain loss in the preparation process. If the mineral powder can be directly made into slurry in the electrolytic cell Electrolysis can greatly simplify the process, reduce intermediate links, save costs and increase product yield. [0004] The essence of slurry e...

Problems solved by technology

[0005] For electrolytic lead, slurry electrolysis can effectively simplify the hydrometallurgical process and reduce costs. However, lead ore slurry electrolysis faces many difficulties in industrial application, such as achieving stable slurry suspension electrolysis and ion concentration in the entire long electrolytic cell. Uniform distribution, liquid circulation between the slurry reaction zone and the electrolysis zone, discharge of deposited sponge lead, etc. These unresolved technical problems directly affect the application and development of the slurry lead electrolysis technology
