Ultrahigh current density electrolysis or electro-deposition groove

Abstract

The invention provides an ultrahigh current density electrolysis or electro-deposition groove comprising a groove body, wherein the groove body is provided with a liquid inlet; a flange is arranged at the outer part of the liquid inlet; a panel is arranged on the inner side wall of the groove body; a closed cavity is formed by the panel and the inner side wall of the groove body; the closed cavity is communicated with the liquid inlet in the groove body; the panel is provided with an electrolyte spraying device and a polar plate limiting device; an anode plate and a cathode plate are placed in the groove body; and a liquid discharging device is arranged on the groove body. According to the ultrahigh current density electrolysis or electro-deposition groove disclosed by the invention, a liquid supplying device is formed by the panel, the inner side wall of the groove body and the closed cavity formed by the panel and the inner side wall of the groove body. The liquid supplying device disclosed by the invention is embedded into the inner side wall of the groove body and a liquid supplying manner that the bottom of the e liquid supplying device is parallel to polar plates is utilized so as to guarantee the electrolyte circulation requirements needed by electrolysis or electro-deposition production under the ultrahigh current density; and meanwhile, the polar plates are not contacted with the liquid supplying device which is embedded into the inner side wall of the groove body, so as to guarantee the safety of the liquid supplying device and the production is smoothly and safely operated.

Description

technical field [0001] The invention relates to the technical field of electrolysis or electrowinning of non-ferrous metals, in particular to an ultra-high current density electrolysis or electrowinning cell. Background technique [0002] Electrolytic refining is the main means of metal refining in the process of non-ferrous metal smelting, and it is also a final link of non-ferrous metal smelting. The advanced technology and equipment directly affect the quality of metals and the level of production capacity. Among non-ferrous metals, the electrolysis or electrowinning process of copper, lead, zinc and nickel is based on the principle of electrochemistry. The cathode and anode are placed in a tank containing a solution containing metal ions, and an electrochemical reaction occurs on the electrodes after electrification. , the metal on the cathode is continuously precipitated and deposited. Since the electrode potentials of various metal ions in the solution determine the o...

Problems solved by technology

However, since the electrolyte inlet tank of the device is hung on the wall of the electrolytic cell, the cathode or anode is very easy to touch the liquid inlet tank in actual production and cause damage to the tank, and even damage the anti-corrosion of the inner wall of the electrolytic cell in severe cases. Leakage of the electrolytic cell caused by the layer, which is not conducive to smooth production and safe operation
