Abstract

The invention discloses a paddle telescopic stirring type pulp electrolytic bath. The paddle telescopic stirring type pulp electrolytic bath comprises a positive electrode copper bar, anode plates, a negative electrode copper bar, cathode plates and an electrolytic film; 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; the lower middle portion of the electrolytic bath is provided with a transversely arranged long-shaft integrated stirring paddle connected with telescopic movable paddles; a transversely arranged spiral conveyor is arranged at the bottom of the electrolytic bath; a conical bottom structure is arranged at the conveying end of the spiral conveyor; the conical bottom is connected with a wet grinder through a discharging pipe; the wet grinder is connected with the electrolytic bath through a conveying pipe. The paddle telescopic stirring type pulp electrolytic bath is reasonable in structure, the distance between the plates is conveniently and accurately controlled due to the V-type lap joint, and reliable contact is ensured; large-area and low-speed sweeping of the long paddles capable of automatically adjusting the radius is suitable for maintaining pulp suspension in a long time and low energy consumption mode; the grinder and the spiral conveyor are combined to achieve reliable pulp suspension and pulp electrolysis, course particles are secondarily smashed so as to promote the electrolytic metal yield, the electrolytic bath is suitable for industrial use, and prospects are wide.

Description

technical field [0001] The invention relates to a paddle telescopic stirring type pulp electrolyzer, which is especially suitable for electrolytic 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] 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 easiest way to realize 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 high during operation. It is very high, and the large electrolytic tank needs multiple stirring devices to realize the normal operation of the electrolysis, and it is impossible to realize the bottom sweeping effect of the electrolytic tank and the continuous treatment of the non-suspendable mineral powder particles to make them suspend, so Existing technology cannot meet the requirements of pulp electrolysis
