Description

Technical Field

[0001] This utility model belongs to the technical field of electrode materials for hydrometallurgy, and in particular relates to a new type of energy-saving anode plate for hydrometallurgy. Background Technology

[0002] In the field of hydrometallurgy, electrolysis is a crucial step in the extraction and refining of non-ferrous metals (such as copper, zinc, nickel, manganese, and cobalt). The anode plate, as one of the core consumables in the electrolytic cell, directly affects electrolysis efficiency, energy consumption, operational stability, production benefits, and production costs through its structural design and performance. Traditional hydrometallurgical anode plates typically use lead-based alloy substrates, with the addition of other metallic elements and the uniform opening of numerous circular liquid flow holes on the plate surface to promote electrolyte flow and mass transfer between the anode and cathode. However, with the increasing demands for energy conservation, green manufacturing, and cost reduction and efficiency improvement in the metallurgical industry, traditional anode plates have revealed several technical bottlenecks: Firstly, the circular liquid flow holes are designed to meet the electrolyte flow requirements. However, the process of creating a large number of holes reduces the mechanical strength of the plate and exacerbates the stress concentration, making it prone to warping and deformation during stamping or use. Secondly, the dense arrangement of circular holes makes it easy for anode mud to accumulate at the edge of the holes, making cleaning difficult, increasing maintenance costs and affecting the continuity of electrolysis; Third, in the actual electrolysis process, uneven liquid flow distribution or large flow resistance can easily lead to local concentration polarization, resulting in increased cell voltage and DC power consumption, which is not conducive to achieving green and low-carbon production under the "dual carbon" target.

[0003] To address these issues, we provide a novel energy-saving anode plate for hydrometallurgy. Utility Model Content

[0004] The purpose of this invention is to provide a new type of energy-saving anode plate for hydrometallurgy, which optimizes the liquid flow holes into a rectangular structure with obtuse interior angles and arranges them in four staggered columns. It adopts an integrated stamping process, which solves the problems of high energy consumption, easy deformation, difficult mud removal, complex manufacturing and high overall cost of existing anode plates.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a novel energy-saving anode plate for hydrometallurgy, comprising an anode plate body; the surface of the anode plate body is provided with a plurality of liquid flow holes, the liquid flow holes being rectangular holes, the liquid flow holes being distributed in four rows, wherein the inner two rows of liquid flow holes are the first and second rows of liquid flow holes, and the outer two rows of liquid flow holes are the third and fourth rows of liquid flow holes; the first and second rows of liquid flow holes correspond to each other longitudinally on the plate surface, the third and fourth rows of liquid flow holes correspond to each other longitudinally on the plate surface, and the inner two rows of liquid flow holes and the outer two rows of liquid flow holes are staggered in the transverse direction.

[0006] The present invention is further configured such that the anode plate body is a rectangular flat plate structure, and the anode plate body is made of lead-based alloy material.

[0007] The present invention is further provided that the two sides of the anode plate body are provided with raised protective teeth, and the protective teeth are integrally formed with the plate surface of the anode plate body.

[0008] The present invention is further configured such that the thickness of the anode plate body is 4–7 mm, and the total area of ​​the liquid flow holes on the anode plate body accounts for 12% to 18% of the total area of ​​the plate surface.

[0009] The present invention is further configured such that the four interior angles of the liquid flow orifice are all obtuse angles, with an angle range between 100° and 150°.

[0010] The present invention is further configured such that the long side of the liquid flow hole extends in the longitudinal direction of the anode plate body, and the short side extends in the transverse direction of the anode plate body.

[0011] This utility model has the following beneficial effects: 1. The rectangular liquid flow hole in this utility model has a larger single-hole flow area than the traditional circular hole. Within a reasonable range of 12%–18% of the total liquid flow hole area, it significantly improves the fluidity and renewal rate of the electrolyte on the anode plate surface, effectively reduces concentration polarization and cell voltage during the electrolysis process, thereby reducing current consumption by about 5% and directly reducing energy consumption in the electrolysis process.

[0012] 2. The anode plate body of this utility model has fewer rectangular holes, a larger stamping area, and an optimized arrangement, reducing the material usage of the anode plate body by 5%–10% and the overall weight by 3%–5%. At the same time, the liquid flow holes and the sheath teeth are formed by one-time stamping, which simplifies the production process and reduces the complexity of the mold.

[0013] 3. The four rows of liquid flow holes of this utility model adopt the arrangement of "inner alignment, outer alignment, and inner and outer staggered", which effectively disperses the stamping stress, significantly suppresses plate deformation, improves the flatness and structural stability of the anode plate, and is conducive to the uniform distribution of electric field in the electrolytic cell, ensuring the stable and efficient operation of the electrolysis process.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-4 This utility model is a novel energy-saving anode plate for hydrometallurgy, comprising an anode plate body 100; the anode plate body 100 has a plurality of liquid flow holes on its surface, the liquid flow holes being rectangular holes, the liquid flow holes being distributed in four rows, wherein the inner two rows of liquid flow holes are the first row of liquid flow holes 101 and the second row of liquid flow holes 102, and the outer two rows of liquid flow holes are the third row of liquid flow holes 103 and the fourth row of liquid flow holes 104; the first row of liquid flow holes 101 and the second row of liquid flow holes 102 correspond to each other in the longitudinal direction on the plate surface, the third row of liquid flow holes 103 and the fourth row of liquid flow holes 104 correspond to each other in the longitudinal direction on the plate surface, and the inner two rows of liquid flow holes and the outer two rows of liquid flow holes are staggered in the transverse direction.

[0022] The novel energy-saving anode plate for hydrometallurgy provided in this embodiment replaces the traditional circular liquid flow holes with rectangular holes with obtuse interior angles. This not only increases the flow cross-sectional area per unit hole but also significantly improves the electrolyte flow capacity at the same opening ratio, thereby improving the electrolyte renewal rate on the electrode surface, reducing concentration polarization, and helping to reduce power consumption. The four rows of liquid flow holes are arranged in a "two inner rows aligned, two outer rows aligned, and inner and outer staggered" manner, which not only ensures the uniform distribution of electrolyte in the width direction of the electrode plate but also disperses the load stress generated during stamping through the staggered layout, further reducing the risk of overall deformation.

[0023] Specifically, the thickness of the anode plate body 100 is 4–7 mm, and the total area of ​​the liquid flow holes on the anode plate body 100 accounts for 12% to 18% of the total plate surface area, ensuring sufficient flow capacity while maintaining the mechanical strength of the anode plate body 100; the four interior angles of the liquid flow holes are all obtuse angles, with an angle range between 100° and 150°, which effectively alleviates the stress concentration phenomenon during the stamping process, suppresses the warping deformation of the plate surface caused by punching, and improves the flatness and structural stability of the product; the long side of the liquid flow holes extends in the longitudinal direction of the anode plate body 100, and the short side extends in the transverse direction of the anode plate body 100.

[0024] Furthermore, the anode plate body 100 is a rectangular flat plate structure, and the anode plate body 100 is made of lead-based alloy material; the two sides of the anode plate body 100 are provided with raised protective teeth 105, and the protective teeth 105 are integrally formed with the plate surface of the anode plate body 100, which simplifies the manufacturing process, reduces mold complexity and material consumption, improves product consistency, and also reduces the capital and energy consumption investment of anode plate manufacturers.

[0025] The specific implementation steps of this embodiment are as follows: First, according to the size requirements of the hydrometallurgical electrolytic cell, a lead-based alloy plate with a thickness of 4–7 mm is selected as the raw material for the anode plate body 100; then, the plate is pre-treated on the surface, including degreasing, pickling and passivation, to ensure the quality of subsequent stamping and corrosion resistance; next, a special stamping die is used to stamp four rows of rectangular liquid flow holes on the anode plate body 100 in one go. The inner two rows (the first row of liquid flow holes 101 and the second row of liquid flow holes 102) are strictly aligned in the longitudinal direction, and the outer two rows (the third row of liquid flow holes 103 and the fourth row of liquid flow holes 104) are also aligned in the longitudinal direction. The inner two rows and the outer two rows are staggered in the transverse direction to disperse the stamping stress and reduce plate deformation; all liquid flow holes are designed as rectangular structures with the long side along the longitudinal direction and the short side along the transverse direction. The anode plate is constructed with four obtuse angles of 100° to 150° to increase the flow area and avoid stress concentration. The total area of ​​the liquid flow holes needs to be precisely controlled within 12% to 18% of the total area of ​​the anode plate surface to balance electrolyte flow efficiency and structural strength. While stamping the liquid flow holes, the sheath teeth 105 on both sides of the anode plate body 100 are simultaneously formed integrally using the same mold, eliminating the need for subsequent welding or assembly, thereby simplifying the process and reducing mold costs and material waste. After stamping, the anode plate is shaped and leveled to eliminate residual stress, and dimensional and surface quality checks are performed. Finally, depending on the application requirements, the anode plate can be coated (such as with a precious metal oxide catalyst layer) to enhance its electrochemical activity and durability, ultimately forming an energy-saving anode plate product that can be used in hydrometallurgical electrolysis systems.
