Embodiment 1

[0039] Example 1: Metal electrolytic refining and waste metal direct electrolytic refining recovery

[0040] When the device is used for electrolytic refining of metals (such as copper, lead, zinc, etc.), the anode material for rough refining is placed in the anode material storage box, and under the action of current, the anode material is oxidized into ions and stored in the electrolyte. The metal ion anode gets electrons to form solid metal and completes electrolytic refining. As the electrolysis process continues, the anode material is continuously reduced, and the anode material only needs to be replenished from the anode material storage box. After electrolysis for a certain period of time, the cathode plate is taken out to obtain electrolytically refined pure metal.

Embodiment 2

[0041] Embodiment 2: electrolytic metal powder material

[0042]When electrolyzing powder materials (such as copper powder, nickel powder, zinc powder, etc.), the raw metal is placed in the anode material storage box, and the powder material obtained from electrolysis is covered on the anode plate. The conductive strips of the plate are blocked, and there is no need to take out the anode plate to scrape the powder. The powder can be scraped regularly in the tank, and the powder that sinks to the bottom is discharged out of the tank through the electric pump or the electrolyte circulation, so as to realize continuous and uninterrupted continuous production. As the electrolysis process continues, the anode material is continuously reduced, and the anode material only needs to be replenished from the anode material storage box. The anode slime will not pollute the powder material that sinks to the bottom of the tank because it is deposited in the anode material storage tank.

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...
