电解生产工艺在湿法冶金过程中广泛应用，永久阴极法在电解规模化生产中应用越来越广泛，但此方法也存在着析出物剥离问题：以较大幅度逐片弯曲阴极板身，使析出物脱离；或用工具逐片撬开析出物在阴极上的边缘后再剥离，这些操作易造成永久阴极的变形、损坏，同时逐片操作的生产效率低，因此需要应用性强的新技术进一步解决剥离永久阴极板上析出物的问题。The electrolytic production process is widely used in hydrometallurgical processes, and the permanent cathode method is increasingly widely used in large-scale electrolytic production. However, 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. At the same time, 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.

一种剥离永久阴极板上析出物的方法，参考图1、图2，在永久阴极板上嵌入金属材料制作的脱板扣，脱板扣或贯穿永久阴极板身，或紧贴板身，通过操作杆实现脱板扣的转动、翻转、撬动等动作，使脱板扣平面偏离永久阴极板平面，带动析出物脱离阴极板平面，使析出物脱离板身；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;
上述步骤所述的脱板扣，其结构可以是与永久阴极板绝缘边组合的整体结构，参考图3，绝缘材料包裹的金属结构材料为操作杆的一部分，操作杆的转动带动脱板扣撬开析出物实现脱板；The stripping buckle described in the above steps may be an integral structure combined with the insulating edge of the permanent cathode plate. Referring to FIG3 , 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;

When the permanent cathode material and the precipitate cannot be closely adhered to realize long-cycle production, 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. In order to ensure the uniformity and reliability of the adsorption force, a certain number of similar materials can be embedded in the permanent cathode plate body to realize the effective adsorption of the precipitate on the cathode plate, that is, the role of the stripping buckle can be ignored and the material with stronger force on the precipitate can be embedded to realize the effective adhesion of the precipitate on the cathode plate. The schematic diagram of its structure refers to Figure 4;
脱板作业时，脱板扣的动作幅度不足以整体脱离析出物时，可以配备必要的震动、拉动、撬动等使析出物脱离永久阴极板身的动作，提高脱板作业的效率；During the board stripping operation, if the movement range of the stripping buckle is not enough to completely separate the precipitate, necessary vibration, pulling, prying and other actions can be provided to separate the precipitate from the permanent cathode plate body to improve the efficiency of the board stripping operation;

The corresponding mechanical device works to achieve the simultaneous removal of multiple permanent cathodes.
该工艺方法提高了永久阴极脱板作业的效率，保护了永久阴极板，实现了不同金属材料的组合在永久阴极板上的灵活运用，拓展了永久阴极工艺应用领域，推动了冶金行业的技术进步。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 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;S2、所述脱板扣和操作杆的材质根据析出物特性决定，当永久阴极板材料与析出物不能紧密粘附实现长周期生产时，所述脱板扣使用与析出物有更强附着力的材料；贯穿永久阴极板身的脱板扣将永久阴极板两侧的析出物吸附在永久阴极板上，为保证吸附力的均匀和可靠性，在永久阴极板身上镶嵌若干数量的与析出物有更强附着力的材料，实现析出物在永久阴极板上的有效吸附；S2. The materials of the stripping buckle and the operating rod are determined according to the characteristics of the precipitate. When the permanent cathode plate material and the precipitate cannot be tightly adhered to achieve long-term production, 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. In order to ensure uniformity and reliability of adsorption force, 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;S3、所述脱板扣的动作幅度不足以整体脱离析出物时，采用震动、拉动或撬动动作实现析出物的整体脱离；S3, when the action amplitude of the stripping buckle is not enough to completely separate the precipitate, the entire precipitate is separated by vibration, pulling or prying;S4、通过操作台实现多块永久阴极板的同时脱板：操作台上对应每块永久阴极板设置有相应的机械装置，多块永久阴极板依次放置在操作台上，每个永久阴极板对应的机械装置工作，实现多块永久阴极板的同时脱板。S4. Simultaneous removal of multiple permanent cathode plates is achieved through an operating table: a corresponding mechanical device is provided on the operating table corresponding to each permanent cathode plate, and multiple permanent cathode plates are placed on the operating table in sequence. The mechanical device corresponding to each permanent cathode plate works to achieve simultaneous removal of multiple permanent cathode plates.
