Definitions
- the invention belongs to the application field of electrolytic technology in hydrometallurgy industry, and in particular relates to a method for stripping precipitates on a permanent cathode plate.
- the electrolytic production process is widely used in hydrometallurgical processes, and the permanent cathode method is increasingly widely used in large-scale electrolytic production.
- this method also has the problem of precipitate stripping: bending the cathode plate body piece by piece with a large amplitude to separate the precipitates; or using tools to pry open the edges of the precipitates on the cathode piece by piece and then stripping them off. These operations can easily cause deformation and damage to the permanent cathode.
- the production efficiency of piece-by-piece operations is low. Therefore, new technologies with strong applicability are needed to further solve the problem of stripping precipitates on the permanent cathode plate.
- the present invention provides a method for stripping precipitates on a permanent cathode plate, aiming to solve the problems that the conventional method easily causes deformation and damage of the permanent cathode plate and low production efficiency of piece-by-piece operation.
- the present invention provides a technical solution: a method for stripping precipitates on a permanent cathode plate, comprising the following steps:
- the stripping buckle is arranged through the permanent cathode plate body.
- the stripping buckle is rotated, flipped and pried by an operating rod.
- the stripping buckle plane deviates from the permanent cathode plate plane through the above-mentioned actions, so that the precipitate is separated from the plate body;
- the materials of the stripping buckle and the operating rod are determined according to the characteristics of the precipitate.
- the stripping buckle uses a material with stronger adhesion to the precipitate; the stripping buckle that runs through the permanent cathode plate body adsorbs the precipitates on both sides of the permanent cathode plate onto the permanent cathode plate.
- a certain number of materials with stronger adhesion to the precipitate are embedded on the permanent cathode plate body to achieve effective adsorption of the precipitate on the permanent cathode plate;
- the board release buckle is arranged close to the board body.
- the stripping buckle is combined with the insulating edge of the permanent cathode plate into an integral structure, and the metal structural material wrapped by the insulating material is a part of the operating rod.
- the operating rod drives the stripping buckle to pry open the precipitate, create stripping conditions or realize stripping.
- the process method improves the efficiency of permanent cathode plate removal operations, protects the permanent cathode plates, realizes the flexible use of combinations of different metal materials on permanent cathode plates, expands the application field of permanent cathode technology, and promotes technological progress in the metallurgical industry.
- Figure 1 is a schematic diagram of a rotary stripping buckle.
- FIG. 2 is a schematic diagram of a prying type stripping buckle penetrating the permanent cathode plate body and closely attached to the plate body.
- Figure 3 is a schematic diagram of the combined structure of the stripping buckle and the insulating edge.
- FIG4 is a schematic diagram of the structure in which other materials are embedded on the cathode plate.
- a method for stripping precipitates on a permanent cathode plate referring to FIG1 and FIG2, a stripping buckle made of metal material is embedded in the permanent cathode plate, the stripping buckle either penetrates the permanent cathode plate body or is closely attached to the plate body, and the stripping buckle is rotated, flipped, pried, etc. by an operating rod, so that the plane of the stripping buckle deviates from the plane of the permanent cathode plate, driving the precipitates to separate from the cathode plate plane, so that the precipitates are separated from the plate body;
- the stripping buckle described in the above steps may be an integral structure combined with the insulating edge of the permanent cathode plate.
- the metal structural material wrapped by the insulating material is a part of the operating rod, and the rotation of the operating rod drives the stripping buckle to pry open the precipitate to realize stripping;
- the materials of the stripping buckle and the operating rod can be selected as needed.
- the stripping buckle can be made of a material with stronger adhesion to the precipitate.
- the stripping buckle penetrates the cathode plate body to adsorb the precipitates on both sides of the cathode plate on the permanent cathode.
- the simultaneous removal of multiple permanent cathodes can be achieved through the operating table: there is a corresponding mechanical device on the operating table corresponding to each permanent cathode, and multiple permanent cathodes are placed on the operating table and are in corresponding positions of the mechanical device.
- the corresponding mechanical device works to achieve the simultaneous removal of multiple permanent cathodes.
- This process method improves the efficiency of permanent cathode plate removal operations, protects permanent cathode plates, realizes the flexible use of different metal material combinations on permanent cathode plates, expands the application field of permanent cathode technology, and promotes technological progress in the metallurgical industry.
- the titanium permanent cathode plate used in nickel electrolysis has an effective size of 890*860*3mm.
- Two 316L stainless steel plate release buckles with a width of 5mm and a length of 20mm are set close to the permanent cathode plate body at the upper edge of the precipitate.
- 3mm diameter 304 stainless steel dots are inlaid on the permanent cathode plate body at intervals of 50mm along the edge of the precipitate.
- a 3mm diameter 304 stainless steel dot is inlaid in every 150*150mm area of the plate body to enhance the adsorption of nickel on the titanium cathode.
- the titanium permanent cathode plate used in cobalt electrowinning has an effective size of 680*660*3mm.
- Two 316L stainless steel plate release buckles with a width of 5mm and a length of 15mm are set on the upper edge of the precipitate to penetrate the permanent cathode plate body.
- the permanent cathode plate body is inlaid with 2.5mm diameter 304 stainless steel dots at intervals of 40mm along the edge of the precipitate, and a 2mm diameter 316 stainless steel dot is inlaid in every 120*120mm area to enhance the adsorption of metal cobalt on the titanium cathode.
- the stainless steel permanent cathode plate used in copper electrowinning has an effective size of 1080*1060*3mm.
- Two 316L stainless steel stripping buckles with a width of 10mm and a length of 25mm are set on the upper edge of the precipitate to penetrate the permanent cathode plate body.
