Description
Technical Field
[0001] This utility model belongs to the field of aluminum electrolytic smelting production technology, and specifically relates to a copper-embedded structure for an aluminum electrolytic anode conductor. Background Technology
[0002] Electrolytic aluminum anode guide rods are an essential piece of equipment in the electrolytic aluminum process, primarily used to fix the anode steel claws in the electrolytic cell. The main material of the electrolytic aluminum anode guide rod is high-strength aluminum alloy, which has excellent corrosion resistance and high strength, capable of withstanding the high temperature and chemical corrosion environment within the electrolytic cell. The quality of the electrolytic aluminum anode guide rod directly affects the quality and yield of aluminum products.
[0003] Currently, the anode guide rods used in electrolytic aluminum production rely on a crimping device for contact connection. However, due to unstable contact resistance, the contact resistance between the two increases during later use, resulting in a rapid increase in the voltage drop of the carbon anode guide rod. This increased contact voltage drop leads to increased energy consumption. Utility Model Content
[0004] To address the aforementioned issues, this invention provides a copper-embedded structure for an aluminum electrolytic anode rod, which utilizes the conductivity of copper to reduce the contact voltage drop between the anode rod and the horizontal aluminum busbar, thereby reducing resistance and energy consumption.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A copper-embedded structure for an aluminum electrolytic anode rod includes an anode rod, a copper-aluminum composite block, and a horizontal aluminum busbar. The copper-aluminum composite block has a copper connecting surface and an aluminum connecting surface, which are arranged opposite to each other. The copper-aluminum composite block is embedded in one side of the anode rod, with the copper connecting surface facing the anode rod. The horizontal aluminum busbar is pressed against the surface of the aluminum connecting surface, and the contact area between the horizontal aluminum busbar and the aluminum connecting surface is smaller than the total area of the aluminum connecting surface.
[0007] Preferably, the anode guide rod has an installation groove, and the copper-aluminum composite block is engaged with the installation groove and fits against the groove wall.
[0008] Preferably, the depth of the mounting groove ranges from 25mm to 35mm, and the length ranges from 900mm to 1100mm.
[0009] Preferably, the length of the anode guide rod is in the range of 2300mm to 2500mm, and the width is in the range of 145mm to 155mm.
[0010] Preferably, the aluminum connecting surface is flush with the surface of the anode guide rod, and the connection is welded.
[0011] Preferably, the width of the mounting groove is the same as the width of the anode guide rod.
[0012] Preferably, one end of the anode guide rod is provided with a through groove, which is used to fix the anode guide rod to the electrolytic cell.
[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows:
[0014] The copper-aluminum composite block is embedded in the anode guide rod and tightly connected by non-ferrous welding. The copper-aluminum composite block has a copper connecting surface and an aluminum connecting surface. During installation, the copper connecting surface faces the anode guide rod and makes contact with it, while the aluminum connecting surface is used to connect the horizontal aluminum busbar. By setting the copper-aluminum composite block in the anode guide rod and utilizing the conductivity of copper, the voltage drop of the anode guide rod and the contact voltage drop between the anode guide rod and the horizontal aluminum busbar can be reduced to a large extent, thereby reducing contact resistance, reducing energy consumption, and effectively reducing operating costs.

[0023] To resolve the above issues, please refer to [link / reference]. Figures 1 to 3 This utility model provides a copper-embedded structure for an aluminum electrolytic anode guide rod 1, including an anode guide rod 1, a copper-aluminum composite block 2, and a horizontal aluminum busbar 3. The copper-aluminum composite block 2 has a copper connecting surface 21 and an aluminum connecting surface 22, which are arranged opposite to each other. The copper-aluminum composite block 2 is embedded and installed on one side of the anode guide rod 1, with the copper connecting surface 21 facing the anode guide rod 1. The horizontal aluminum busbar 3 is pressed against the surface of the aluminum connecting surface 22, and the contact area between the horizontal aluminum busbar 3 and the aluminum connecting surface 22 is smaller than the total area of the aluminum connecting surface 22. Among them, the copper-aluminum composite block 2 is plate-shaped and is a new type of material that cannot be separated by welding copper plates and aluminum plates together through methods such as cold rolling, hot rolling, explosive bonding, or explosive rolling. In this embodiment, the copper-aluminum composite block 2 is manufactured by explosive bonding. The horizontal aluminum busbar 3 is a conductive element used for power transmission and distribution. It is usually installed horizontally and is widely used in electrolytic aluminum, power systems, and industrial equipment. It has the characteristics of high conductivity, light weight, corrosion resistance, and low cost. The conductor resistivity of copper is ≤0.01724mm2 / M, and its conductivity is second only to silver. It can effectively reduce resistance and improve the conductivity of the anode rod 1.
[0024] In optional embodiments, such as Figure 3As shown, the anode guide rod 1 has an installation groove 11, and the copper-aluminum composite block 2 is snapped into the installation groove 11 and fits against the groove wall of the installation groove 11; the aluminum connecting surface 22 is flush with the surface of the anode guide rod 1 and welded together, and the width of the installation groove 11 is the same as the width of the anode guide rod 1. Specifically, the operator creates the installation groove 11 by milling, turning, laser cutting, or stamping. In this embodiment, the anode guide rod 1 has a square cross-section, and the installation groove 11 penetrates the anode guide rod 1, which increases the contact area between the anode guide rod 1 and the copper-aluminum composite block 2, and significantly reduces the resistance within this volume range, improving the conductivity of the anode guide rod 1; at the same time, it avoids the copper-aluminum composite block 2 protruding, which would affect the aesthetics, conductivity, and volume.
[0025] In an optional embodiment, the groove depth of the mounting groove 11 ranges from 25mm to 35mm, and the length ranges from 900mm to 1100mm. Specifically, the groove depth of the mounting groove 11 can be 25mm, 28mm, 30mm, 32mm, or 35mm, and the length can be 900mm, 950mm, 1000mm, or 1100mm. In practical applications, these dimensions include, but are not limited to, those mentioned above. In this embodiment, the groove depth of the mounting groove 11 is 30mm, and the length is 1000mm.
[0026] In an optional embodiment, the length of the anode guide rod 1 ranges from 2300mm to 2500mm, and the width ranges from 145mm to 155mm. Specifically, the length of the anode guide rod 1 can be 2300mm, 2400mm, or 2500mm, and the width can be 145mm, 150mm, or 150mm. In practical applications, this includes, but is not limited to, the dimensions and specifications mentioned above. In this embodiment, the length of the anode guide rod 1 is 2400mm and the width is 150mm, wherein the width of the mounting groove 11 is 150mm.
[0027] In optional embodiments, such as Figure 2 As shown, a through groove 12 is provided at one end of the anode guide rod 1. The through groove 12 is used to fix the anode guide rod 1 to the electrolytic cell. Specifically, the through groove 12 is set along the width direction of the anode guide rod 1. The anode guide rod 1 is stably installed in the electrolytic cell by the cooperation of the through groove 12 and the nut, ensuring its stability and safety in the electrolytic cell.
[0028] The copper-aluminum composite block 2 is embedded into the mounting groove 11 of the anode guide rod 1. The copper connecting surface 21 of the copper-aluminum composite block 2 is in contact with the bottom wall of the mounting groove 11, and the side wall of the mounting groove 11 is in contact with the side wall of the mounting groove 11, so that the two are tightly fitted and pressed together. In order to further improve the connection stability between the two, the edge lines of the two mating surfaces are welded together with colored solder to prevent the copper-aluminum composite block 2 from detaching from the mounting groove 11. Finally, the anode guide rod 1 with the copper-aluminum composite block 2 is pressed onto the horizontal aluminum busbar 3, wherein the horizontal aluminum busbar 3 is connected to the aluminum connecting surface 22 of the copper-aluminum composite block 2.
[0029] In summary, the copper-aluminum composite block 2 is embedded in the anode guide rod 1 and tightly connected by colored welding. The copper-aluminum composite block 2 has a copper connecting surface 21 and an aluminum connecting surface 22. During installation, the copper connecting surface 21 faces the anode guide rod 1 and is in contact with the anode guide rod 1, while the aluminum connecting surface 22 is used to connect the horizontal aluminum busbar 3. By setting the copper-aluminum composite block 2 on the anode guide rod 1 and utilizing the conductivity of copper, the voltage drop of the anode guide rod 1 and the contact voltage drop between the anode guide rod 1 and the horizontal aluminum busbar 3 can be reduced to a large extent, reducing contact resistance, thereby reducing energy consumption and effectively reducing operating costs.
