Abstract
The utility model provides a cathode device used in a deposition metal, which relates to a cathode used in a deposition metal in the process of a hydrometallurgy, and which is in particular used for improving the cathode basal plate which is used in electrowinning production metal or electrorefining. The utility model is characterized in that the edge of the electrolysis cathode plate is enchased with insulation strip material. Because the insulation material enchased on the edge of the electrode basal plate changes the power line distributing status between the cathode and the anode, lowers the power line density of the edge of the cathode, reduces the deposit speed of metal ions on the edge of the cathode, and eliminates the cathode edge agglomeration phenomenon caused by high current density and concentrated power line distribution, and the targets of reducing and eliminating the phenomena of electrolysis products edge agglomeration, tip-of-the-tongue and so on are achieved, through which makes the plate shaped electrolysis products have even thickness and have no edge agglomeration. The physical form quality of the products is greatly improved.
Description
Technical field
A kind of electrowinning cathode assembly relates to the negative electrode that a kind of hydrometallurgy process electrowinning is used, and produces the cathode base that metal or electrorefining use especially for electrodeposition and improves.
Background technology
At present, in hydrometallurgy process, usually adopt insoluble anode and soluble anode electrolysis production electrolysis cathode product.Electrodeposition is produced in the process of metal and electrorefining metal, and negative electrode and anode add under the effect of electric power outside, and electrochemical reaction takes place, and metallic cation constantly obtains electronics, separates out deposition on negative electrode, forms the negative electrode product.And what and deposition quality metal ion deposit on pole plate, and be closely related with electric force lines distribution in polarization of electrode and the bulk electrolysis liquid (being the quadratic distribution of electric current).The solution metal positively charged ion moves to the cathodic process from anode under the driving of electric field, and two kinds of power are arranged: the magnetic field force that motivating force that the concentration concentration difference forms and extra electric field form works.Near anode, the current potential potentiometric surface is not the plane that is parallel to negative plate, and there are evident difference in the current potential and the central authorities at groove two ends, and Potential distribution is also inhomogeneous between central two electrodes, and electric force lines distribution is left-right symmetry, asymmetric up and down near negative electrode.Particularly the electric force lines distribution of cathode edge is apparently higher than other positions, thereby causes cathode-side portion metal deposition too fast, is easy to generate to spread all over the knot grain, influences the physical appearance quality of electrolytic production.Therefore, in order to reduce the limit portion knot grain of electrolysis plate-like product, most of manufacturer, adopted the method that strengthens cathode size to reduce limit portion knot grain, yet adopt this way, cause negative electrode product limit portion thickness to be significantly less than the phenomenon at middle part again, influence the physical appearance quality of product equally.
In the soluble anode electrolytic process, its quality product is subjected to the influence of electric force lines distribution inequality particularly serious, and in order to improve the visual appearance of plate-like cathodes product, many electrorefinings factory has adopted means of different, but effect is all not obvious.
Summary of the invention
The purpose of this utility model is the deficiency that exists at above-mentioned prior art, and a kind of cathode assembly that can effectively reduce and eliminate the cathode edge effect, improve the electrolysis cathode quality product is provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of electrowinning cathode assembly is characterized in that being inlaid with the insulation strip material at the edge of electrolysis cathode pole plate.
A kind of electrowinning cathode assembly of the present utility model, the strip material that it is characterized in that insulating is embedded in the bottom and side portion edge of electrolysis cathode pole plate, and the upper end is higher than liquid level of electrolyte.
A kind of electrowinning cathode assembly of the present utility model is characterized in that the material of the insulation strip material inlayed is Reinforced Polypropylene, chlorinated polyvinyl chloride or glass reinforced plastic.
A kind of electrowinning cathode assembly of the present utility model, it is characterized in that battery lead plate be inlaid into the insulation strip material the degree of depth be 10-20mm.
A kind of electrowinning cathode assembly of the present utility model, the width that it is characterized in that described insulation strip material is 3 times of negative electrode product thickness, is 20-30mm.
Cathode assembly of the present utility model is applicable in the electrodeposition or electrorefining process of bright sulfur acid medium, chlorination medium and nitration mixture medium.Changed electric force lines distribution situation between the Yin and Yang utmost point owing to be embedded in the insulating material at electrode base board edge, reduce cathode-side portion power line density, reduce metal ion in the sedimentary speed of cathode edge, elimination is the too high and too concentrated cathode-side portion knot grain phenomenon that causes of electric force lines distribution because of current density, thereby reach the purpose that reduces and eliminate phenomenons such as electrolytic production limit portion knot grain, lip limit, make even, boundless knot grain of tabular electrolytic production thickness, its physical appearance quality is greatly improved.
Description of drawings
Fig. 1 is the structural representation of device of the present utility model.
Embodiment
A kind of electrowinning cathode assembly is inlaid with insulation strip material 2 at the edge of electrolysis cathode pole plate 1.The insulation strip material is embedded in the bottom and side portion edge of electrolysis cathode pole plate, and the upper end is higher than liquid level of electrolyte.The material of the insulation strip material of inlaying is Reinforced Polypropylene, chlorinated polyvinyl chloride or glass reinforced plastic.The degree of depth that battery lead plate is inlaid into the insulation strip material is that the width of 10-20mm insulation strip material is 3 times of negative electrode product thickness, is 20-30mm.
The utility model adopts the method for blocking-up cathode-side portion's power line and slowing down cathode limit portion ion migration speed, to reduce the sedimentation velocity of cathode-side portion metal ion in the electrolytic process, thereby less and reduce fringing effect in the electrolytic process, make the electrolysis cathode product in process of growth limit portion metal deposition speed less than or be equal to negative electrode middle part metal deposition speed.
The utility model adopts the insulating material making such as Reinforced Polypropylene, chlorinated polyvinyl chloride or glass reinforced plastic preferably of heatproof effect to improve the frame material of cathode edge effect in the electrolytic process, carry out the design of frame according to the negative electrode physical size, guaranteeing that part with three about 15mm of limit portion of negative electrode is embedded among the frame, and this insulating frame material is fixed in the electrolyzer by diaphragm bag or electrolyzer support.The frame width of this device is three times of negative electrode product thickness.Install additional after the repacking, can obviously reduce cathode-side portion metal deposition speed, improve the physical appearance quality of negative electrode product.
