Abstract

The invention discloses a paddle included angle variable type pulp electrolytic bath. The paddle included angle variable type pulp electrolytic bath comprises a positive electrode copper bar, anode plates, a negative electrode copper bar, cathode plates, an electrolytic film and a stirrer; the stirrer is composed of a stirring power device, a stirring shaft and fan blades; the anode plates and the cathode plates are connected with the positive electrode copper bar and the negative electrode copper bar in a V-type lap joint mode; a rotary drum is arranged on the periphery of the fan blades; the fan blades and the rotary drum are coaxial; paddle shafts are fixed on the rotary drum; the paddle shafts are connected with movable paddles rotating around the paddle shafts. The paddle included angle variable type pulp electrolytic bath is simple and reasonable in structure; the anode plates and the cathode plates are connected with the positive electrode copper bar and the negative electrode copper bar in the V-type lap joint mode, so that the distance between the anode plates and the cathode plates is conveniently and accurately controlled, and reliable contact is ensured; low speed of the stirrer is suitable for maintaining pulp suspension in a long time and low energy consumption mode; high speed of the stirrer facilitates energy consumption reduction; short-time and high-speed jet-flow bottom stirring can make sedimentary pulp suspend again rapidly and efficiently. The combination of high speed and low speed of the stirrer can enhance advantages and avoid disadvantages, and the paddle included angle variable type pulp electrolytic bath is particularly suitable for being used in scientific research and small-scale production, and is wide in application prospect.

Description

technical field [0001] The invention relates to an ore pulp electrolytic cell with a variable blade angle, which is especially suitable for electrolyzing ore 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 ...

AI Technical Summary

Problems solved by technology

[0005] Mineral powder will settle in the electrolytic tank. The biggest difficulty in the actual electrolysis process is the suspension of the ore pulp. If the ore pulp cannot achieve a good suspension, the acid produced by electrolysis cannot react well with the mineral powder and dissolve the mineral powder. The speed of the electrolysis slows down, and the concentration of metal ions in the electrolytic cell is also difficult to increase, so that the electrolysis cannot be carried out smoothly.

If electrolysis cannot be carried out smoothly, the acid produced by electrolysis will be less, and the speed of mineral powder dissolution will be slower, resulting in a vicious circle, which will eventually paralyze the electrolysis work

[0006] The most common means to achieve slurry suspension is stirring, but ordinary mechanical stirring can only make the slurry suspend better when the stirring paddle is small and stirring fast, but the energy consumption of such a stirring device will be very high during operation. High, and large-scale electrolyzers require multiple stirring devices to achieve normal operation of electrolysis, and cannot simultaneously sweep the bottom of the electrolyzer, so the existing technology cannot meet the requirements of pulp electrolysis
