Description

Technical Field

[0001] The invention belongs to the technical field of anode guide rod groups for aluminum electrolytic cells, and in particular relates to an anode guide rod group. Background Art

[0002] In the aluminum electrolysis production process, the anode guide rod assembly is the core part, and its components include aluminum guide rods, steel-aluminum composite sheets, steel claws and anode carbon blocks. The steel claws of the anode guide rod assembly have high voltage drop and uneven current distribution during service. The claws at both ends of the steel claws have low current, while the claws in the middle have high current, which leads to an increase in the average voltage drop of the steel claws. Reducing the anode voltage drop is an important research direction in the industry and a hot issue for many scholars.

[0003] Therefore, an anode guide rod assembly is needed. Summary of the invention

[0004] The purpose of the present invention is to provide an anode guide rod assembly to solve the problems of high voltage drop, large current loss and low strength and easy falling off of the connection part between the steel claw and the guide rod in the traditional technology.

[0005] An anode guide rod assembly, comprising:

[0006] Anode guide rod, steel claw cross beam, steel claw head, connection structure, steel-aluminum explosion welding block;

[0007] The connecting structure is located on the side of the anode guide rod, and the connecting structure includes multiple groups of connecting plates, and the connecting plates include mutually connected steel-aluminum composite plates and aluminum connecting plates, and the steel-aluminum composite plates include steel plates and aluminum plates, one end of the aluminum connecting plate is welded to the aluminum plate, and the other end of the aluminum connecting plate is welded to the anode guide rod, and the steel plate is welded to the steel claw crossbeam; the steel-aluminum explosion welding block includes a steel block and an aluminum block, and the steel block is welded to the steel claw crossbeam, and the anode guide rod is welded to the aluminum block.

[0008] Specifically, the connection structure is located at the side of the anode guide rod, including that the connection structure is respectively arranged on two opposite sides of the anode guide rod.

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

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

[0011] Compared with the prior art, the present invention has the following advantages: compared with the traditional anode guide rod group, the anode guide rod group proposed in the present invention has three transfer points in the steel claw beam instead of the original one, so that the current transfer position is more uniform, and the path used by the current from the aluminum guide rod to the steel claw head is shorter, thereby reducing the voltage drop when the current passes through the anode steel claw, thereby achieving the effect of energy saving and consumption reduction.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operate in a specific position, and therefore cannot be understood as a limitation on the present application. In addition, the terms "include", "comprise", "have" and their variations all mean "include but are not limited to", unless otherwise specifically emphasized.

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0020] In addition, in the description of the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0021] At present, the steel claw part of the anode guide rod group has a high voltage drop and uneven current distribution during the conduction process. Specifically, the current at the claws at both ends of the steel claw is small, and the current in the middle claw is large, which leads to an increase in the average voltage drop of the steel claw. The current is more concentrated at the claw head, making the current distribution uniform in the claw head and the electrolyte poor. As a result, the electric energy consumed during use is high and the cost of use is high. At the same time, the connection between the steel claw and the guide rod in the anode guide rod group is relatively weak, and there is also a problem of easy falling off during use.

[0022] In order to overcome the deficiencies in the prior art, an anode guide rod group is proposed. By designing an anode guide rod group, the device mainly includes a connection structure 3, which is located on the side of the anode guide rod 1. The connection structure can make the current pass through the aluminum guide rod and then be transferred to the steel claw crossbeam 21 in multiple ways (for example, 3 ways), and then distribute the current to the nearest steel claw head 22 through the crossbeam 21. Compared with the traditional anode guide rod group, the steel claw crossbeam 21 changes from the original 1 transfer point to 3 transfer points, and the transfer position is relatively uniform. The path used 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, which plays a role in energy saving and consumption reduction.

[0025] In different embodiments, the specific manner of arranging the connection structure on the side of the anode conductor rod may be different. In one embodiment, the connection structure 3 is arranged on opposite sides of the anode conductor rod 1 .
