Description

Technical Field

[0001] This utility model relates to the field of non-ferrous metal electrolytic refining technology, and more specifically, to a high conductivity copper-clad steel composite beam stainless steel cathode plate. Background Technology

[0002] In the electrolytic refining process of copper, the cathode plate is one of the core components, and its performance directly affects electrolysis efficiency, product quality, and production costs. Currently, the cathode plates widely used in industry are mainly stainless steel cathode plates. Stainless steel cathode plates have good corrosion resistance and a certain strength, but their electrical conductivity is relatively low (approximately 3%-5% of that of copper).

[0003] Based on the above, the inventors have discovered the following problems with the existing technology: the high resistivity of stainless steel causes a large voltage drop and Joule heat to be generated when the cathode plate beam is energized, which not only wastes electrical energy but may also cause uneven electrolyte temperature due to local overheating, affecting the uniform deposition of copper ions and reducing the surface quality of the cathode copper. During electrolysis, the uneven deposition of cathode copper and frequent hoisting operations can easily cause the stainless steel cathode plate to warp or twist, affecting its verticality in the electrolytic cell and resulting in poor cathode copper plate shape. Therefore, in view of this, the inventors have studied and improved the existing structure to provide a high-conductivity copper-clad steel composite beam stainless steel cathode plate, in order to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a high-conductivity copper-clad steel composite beam stainless steel cathode plate. It can improve conductivity by using copper-clad steel composite material to manufacture the conductive beam and optimize the lug connection structure, thereby reducing power consumption, improving the quality of cathode copper, and increasing the overall strength and service life of the cathode plate.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A high-conductivity copper-clad steel composite beam stainless steel cathode plate includes a cathode plate body, a conductive crossbeam, and a base support. The conductive crossbeam and the base support are welded and fixed to the upper and lower parts of the cathode plate body, respectively. The upper and lower parts of the cathode plate body are respectively provided with gap one and gap two. A connecting plate is fixedly connected to one side of the conductive crossbeam. A mounting seat is bolted to the upper part of the connecting plate. A recess is installed above the mounting seat. A hanging lug is fixedly connected to the upper part of the recess, and a fastening button is threaded to one side of the recess. A strip plate is fixedly connected to the lower part of the base support, and a conductive rod is installed on the inner side of the strip plate.

[0009] Furthermore, a recessed layer is fixedly provided on the outer surface of the cathode plate body, and the cathode plate body is made of stainless steel.

[0010] Furthermore, the conductive beam is I-shaped and is a profile made of copper-clad steel composite material. The copper-clad steel composite material consists of an inner steel core and an outer copper layer, wherein the steel core accounts for 60%-80% of the cross-sectional area and the copper layer accounts for 20%-40% of the cross-sectional area. The steel core is Q235 carbon structural steel and the copper layer is T2 copper.

[0011] Furthermore, the connection between the conductive crossbeam and the base and the cathode plate body is formed by argon arc welding, and the weld is ground smooth after welding.

[0012] Furthermore, the hooks are symmetrically arranged on both sides of the upper part of the connecting plate, and the structure of each set of hooks is the same.

[0013] Furthermore, a locking post is fixedly provided below the recess, and a threaded groove is provided on the inner side of the recess. The fastening button passes through the mounting base and is threadedly connected to the threaded groove. A locking groove is provided on the inner side of the mounting base, and the locking groove is engaged with the locking post.

[0014] Furthermore, the conductive rods are provided in multiple groups, which are equidistantly distributed on the inner side of the strip plate, and the structure of each group of conductive rods is consistent.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This design achieves a combination of high conductivity and high mechanical strength by using copper-clad steel composite material to manufacture an I-shaped conductive beam. The outer copper layer (T2 copper) of the copper-clad steel composite material provides excellent conductivity close to that of pure copper, significantly reducing the beam's resistance and heat generation during energization, effectively saving energy, and avoiding localized overheating of the electrolyte. This results in more uniform copper ion deposition and significantly improves the surface smoothness and density of the cathode copper. The internal steel core (Q235) provides sufficient bending and tensile strength, which, combined with the I-shaped cross-section, greatly enhances the overall rigidity of the cathode plate, effectively resisting deformation during electrolysis and hoisting. This design fundamentally solves the contradiction between poor conductivity and insufficient strength of traditional stainless steel cathode plates, representing a superior structural innovation.

[0018] (2) This solution achieves rapid replacement and stable connection of the hanging ears by setting up a modular, detachable hanging ear connection structure consisting of a mounting base, a recessed base, a locking post, a locking groove, and a fastening button. The recessed base is connected to the locking groove on the mounting base by the locking post below it, and is locked in place by the fastening button screwed into the threaded groove. At the same time, the mounting base is detachably connected to the connecting plate by bolts. This design not only ensures the connection reliability of the hanging ears during power-on and hoisting, but also allows for easy individual replacement of the hanging ears or connecting parts when they are worn or damaged due to long-term use, without the need to scrap the entire cathode plate. This greatly reduces maintenance costs and downtime, improves equipment utilization and economy, and has significant practical value. Attached Figure Description

[0027] Example:

[0028] Please see Figure 1-5A high-conductivity copper-clad steel composite beam stainless steel cathode plate includes a cathode plate body 1, a conductive crossbeam 2, and a base support 4. The conductive crossbeam 2 and the base support 4 are welded and fixed to the upper and lower parts of the cathode plate body 1, respectively. The upper and lower parts of the cathode plate body 1 are respectively provided with gap 12 and gap 13. A connecting plate 3 is fixedly connected to one side of the conductive crossbeam 2. A mounting seat 7 is bolted to the upper part of the connecting plate 3. A recessed seat 8 is installed above the mounting seat 7. A hanging ear 9 is fixedly connected to the upper part of the recessed seat 8, and a fastening button 10 is threaded to one side of the recessed seat 8. A strip plate 6 is fixedly connected to the lower part of the base support 4. A conductive rod 11 is installed on the inner side of the strip plate 6.

[0029] See Figure 1 and Figure 2 The cathode plate body 1 has a recessed layer 5 fixed on its outer surface, and the cathode plate body 1 is made of stainless steel.

[0030] See Figure 1 and Figure 5 The conductive beam 2 is I-shaped and is made of copper-clad steel composite material. The copper-clad steel composite material consists of an inner steel core and an outer copper layer. The steel core accounts for 60%-80% of the cross-sectional area, and the copper layer accounts for 20%-40% of the cross-sectional area. The steel core is Q235 carbon structural steel, and the copper layer is T2 copper. The conductive beam 2 provides excellent conductivity close to that of pure copper, which greatly reduces the resistance of the beam and the heat generated when energized, effectively saves electrical energy, avoids local overheating of the electrolyte, makes copper ion deposition more uniform, and significantly improves the surface flatness and density of the cathode copper.

[0031] See Figure 4 and Figure 5 The connection between the conductive beam 2 and the base support 4 and the cathode plate body 1 is formed by argon arc welding, and the weld is ground smooth after welding.

[0032] See Figure 1 and Figure 2 The hanging ears 9 are symmetrically arranged on both sides above the connecting plate 3. Each set of hanging ears 9 has the same structure and is used to connect external components.

[0033] See Figure 4 and Figure 5 A locking post 16 is fixedly provided below the recessed seat 8, and a threaded groove 15 is provided on the inner side of the recessed seat 8. The fastening button 10 passes through the mounting seat 7 and is threadedly connected to the threaded groove 15. A locking groove 14 is provided on the inner side of the mounting seat 7. The locking groove 14 is engaged with the locking post 16. The locking groove 14 and the locking post 16 are used to cooperate with the fastening button 10 to quickly install and remove the hanging ear 9.

[0034] See Figure 3 and Figure 4Multiple sets of conductive rods 11 are provided and are distributed at equal intervals on the inner side of the strip plate 6. Each set of conductive rods 11 has the same structure and composition. The conductive rods 11 are used to contact the conductive busbar of the electrolytic cell.

[0035] In use: First, the cathode plate of this invention is suspended from the conductive busbar of the copper electrolysis cell via the lug 9. Current is introduced through the lug 9 and the recess 8, primarily conducted to the entire cathode plate body 1 through the copper layer outside the conductive beam 2. During electrolysis, copper ions are reduced and deposited on the surface of the cathode plate body 1. Due to the low resistance and good heat dissipation of the conductive beam 2, the cell voltage is stable, and the cathode copper deposition is uniform and dense. The cathode plate has high overall strength and is not easily deformed. When components such as the lug 9 or the recess 8 are damaged, the fastening knob 10 can be loosened first, and the recess 8 can be removed from the mounting base 7 for replacement, or the mounting base 7 can be removed for maintenance; the operation is simple. This cathode plate has superior comprehensive performance, is energy-saving, efficient, long-lasting, and offers significant economic benefits.
