Description

Technical Field

[0001] This utility model belongs to the technical field of anode guide rod assembly for aluminum electrolysis cells, and specifically relates to an anode guide rod assembly. Background Technology

[0002] In the aluminum electrolysis production process, the anode guide rod assembly is a core component, consisting of aluminum guide rods, steel-aluminum composite sheets, steel claws, and anode carbon blocks. During service, the steel claw section of the anode guide rod assembly experiences high voltage drop and uneven current distribution, with lower current at the claw ends and higher current in the middle, leading to an increased average voltage drop. Reducing the anode voltage drop is an important research direction in the industry and a hot topic for many scholars.

[0003] Therefore, an anode guide rod assembly is needed. Utility Model Content

[0004] The purpose of this invention is to provide an anode guide rod assembly that solves the problems of high voltage drop, large current consumption, and low strength and easy detachment of the connection between the steel claw and the guide rod in traditional anode guide rod assemblies.

[0005] An anode guide rod assembly, comprising:

[0006] Anode guide rod, steel claw crossbeam, steel claw head, connecting structure, steel-aluminum explosion weld block;

[0007] The connecting structure is located on the side of the anode guide rod. The connecting structure includes multiple sets of connecting plates. Each connecting plate includes interconnected steel-aluminum composite plates and aluminum connecting plates. The steel-aluminum composite plates contain steel sheets and aluminum sheets. One end of the aluminum connecting plate is welded to the aluminum sheet, and the other end of the aluminum connecting plate is welded to the anode guide rod. The steel sheet is welded to the steel claw beam. The steel-aluminum explosion weld block contains steel blocks and aluminum blocks. The steel block is welded to the steel claw beam, and the anode guide rod is welded to the aluminum block.

[0008] Specifically, the connecting structure is located on the side of the anode guide rod, including that the connecting structure is respectively provided on both sides of the anode guide rod.

[0009] Specifically, the connection structure includes 6 sets of connecting pieces.

[0010] Preferably, the steel-aluminum composite sheet in the connecting piece is located on the outer edge of the corresponding side.

[0011] Compared with the prior art, the present invention has the following advantages: The anode guide rod assembly proposed in this invention, compared with the traditional anode guide rod assembly, has three transmission points instead of one, making the current transmission position more uniform and the path taken by the current from the aluminum guide rod to the steel claw head shorter, thereby reducing the voltage drop when the current passes through the anode steel claw and playing a role in energy saving and consumption reduction.

[0015] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be described below in conjunction with the accompanying drawings. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0017] In the description of the embodiments of this application, the words "exemplary," "for example," or "for instance" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplary," "for example," or "for instance" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "exemplary," "for example," or "for instance" is intended to present the relevant concepts in a specific manner.

[0018] In the description of the embodiments of this application, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In addition, the terms "comprising," "including," "having," and their variations all mean "including but not limited to," unless otherwise specifically emphasized.

[0019] In the description of the embodiments in this application, the terms "horizontal," "vertical," "hanging," and "vertical" do not imply that the components are required to be absolutely horizontal or hanging, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] Furthermore, in the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] Currently, the steel claw section of the anode conductor assembly exhibits high voltage drop and uneven current distribution during conduction. Specifically, the current is low at both ends of the claw and high at the middle, leading to an increased average voltage drop and current concentration at the claw tips, resulting in poor current uniformity in the claw tips and electrolyte. Consequently, this results in higher energy consumption and increased operating costs. Furthermore, the connection between the steel claw and the conductor in the anode conductor assembly is relatively weak, making it prone to detachment during use.

[0022] To overcome the shortcomings of existing technologies, an anode guide rod assembly is proposed. This assembly mainly includes a connection structure 3 located laterally to the anode guide rod 1. This connection structure allows current to be transmitted through the aluminum guide rod in multiple paths (e.g., three paths) to the steel claw crossbeam 21. The crossbeam 21 then distributes the current to the nearest steel claw head 22. Compared to traditional anode guide rod assemblies, the steel claw crossbeam 21 has three transmission points instead of one, resulting in a more uniform transmission position. The path taken by the current from the aluminum guide rod 1 to the steel claw head 22 is shorter, thereby reducing the voltage drop when the current passes through the anode steel claw and achieving energy saving and consumption reduction.

[0023] An anode guide rod assembly includes: an anode guide rod 1, a steel claw crossbeam 21, a steel claw head 22, a connecting structure 3, and a steel-aluminum explosion weld block 4;

[0024] The connecting structure 3 is located to the side of the anode guide rod 1. The connecting structure 3 includes multiple sets of connecting plates. Each connecting plate includes a steel-aluminum composite plate 31 and an aluminum connecting plate 32 that are connected to each other. The steel-aluminum composite plate 31 includes a steel sheet 311 and an aluminum sheet 312. One end of the aluminum connecting plate 32 is welded to the aluminum sheet 312, and the other end of the aluminum connecting plate 32 is welded to the anode guide rod 1. The steel sheet 311 is welded to the steel claw beam 21. The steel-aluminum explosion weld block 4 includes a steel block 41 and an aluminum block 42. The steel block 41 is welded to the steel claw beam 21, and the anode guide rod 1 is welded to the aluminum block 42.

[0025] In different embodiments, the specific manner in which the connecting structure is arranged laterally on the anode guide rod can vary. In one embodiment, the connecting structure 3 is provided on opposite sides of the anode guide rod 1.

Figure 1 As shown, an anode guide rod assembly includes: an anode guide rod 1, a steel claw beam 21, a steel claw head 22, a connecting structure 3, and a steel-aluminum explosion weld block 4; wherein the anode guide rod 1 is an aluminum guide rod. First, the steel block 41 in the steel-aluminum explosion weld block 4 is welded to the steel claw beam 21, and the anode guide rod 1 is welded to the aluminum block 42. Then, positioning lines are drawn on the anode steel claw beam 21, and the steel sheet 311 of the steel-aluminum composite sheet is partially welded to the anode steel claw beam 21. One end of the aluminum connecting plate 32 is welded to the aluminum sheet 312 of the steel-aluminum composite sheet 31, and the other end is welded to the side of the anode guide rod 1.

[0027] In different embodiments, the connection structure may be located differently on the side of the anode guide rod. In one specific embodiment, the steel-aluminum composite sheet 31 in the connection piece is located on the outer edge of the corresponding side.

Figure 2 As shown, connecting structures 3 are welded to both sides of the anode guide rod, and steel-aluminum composite sheet 31 is located on the outer edge of the corresponding side.
