Anode scrap-free tandem electrolyzing device with anode material storing box

Abstract

The invention provides an anode scrap-free tandem electrolyzing device with an anode material storing box, wherein the anode scrap-free tandem electrolyzing device is applied to the fields such as the electrolytic refining of metal, the electrolytic production of metal powder material, the electrolytic recovery of waste metal and the like. The anode scrap-free tandem electrolyzing device is characterized in that the anode material storing box is arranged at one side of an electrolytic bath, a metal inner box of the anode material storing box is connected with an anode plate through a conductive yoke plate, and the electrolyzed anode material is oxidized into metal ions in the box and is distributed into the electrolytic bath due to the diffusion of the ions and the circulation of electrolyte; the anode plate is made from the metal or the alloy which can not be chemically dissolved by the electrolyte, wherein the metal activity of the metal or the alloy is lower than that of the electrolyzed metal rather than the electrolyzed anode material; the electrolysis material is added from the anode material storing box and is free from the anode scrap; pole plates in the groove are connected with one another in series, and the electrolyte is isolated due to the effective combination among the anode plate, a cathode and pole plate installing notches. According to the anode scrap-free tandem electrolyzing device, the anode does not need to be changed, the anode material can be conveniently added, the anode scrap of the anode plate is unavailable, the use quantity of the anode raw material in the groove is low, and the anode scrap-free tandem electrolyzing device has the characteristics of being energy-source-saving, investment-saving, and high in production efficiency.

Description

Technical field: [0001] The invention relates to an electrolysis device for aqueous solution, in particular to a series electrolysis device without residual electrodes with an anode material storage box. It is used in the fields of metal electrolytic refining, electrolytic production of metal powder materials, electrolytic recycling of scrap metal, etc. Background technique: [0002] Since H. David, a British scientist, electrolyzed molten caustic soda to produce potassium and sodium in 1807, great progress has been made in the level of technical equipment, production scale, quality of electrolysis products, and reduction of energy consumption. Today, the electrolytic refining of non-ferrous metals in the world exceeds 40 million tons, and the electrolysis of copper, lead and zinc in China alone has reached more than 15 million tons, and the electrolysis of copper exceeded 5 million tons in 2011. [0003] In the current metal electrolytic refining process, there are also so...
