[0002] Anode guide rod group usually refers to the equipment components used in the electrolytic aluminum industry, which is responsible for transmitting current to the anode carbon block to complete the redox reaction in the electrolytic process. The design of the anode guide rod group is crucial to the efficiency and stability of the entire electrolytic process. In recent years, with the development of the electrolytic aluminum industry, the requirements for anode guide rod groups have become increasingly higher, especially in terms of improving current efficiency, reducing energy consumption, and extending equipment life.

[0003] In the prior art, the anode guide rod group mainly includes an anode guide rod, an anode steel claw, and a steel-aluminum composite connection structure for welding the anode guide rod and the anode steel claw together. Among them, the steel-aluminum composite connection structure is usually a steel-aluminum explosion welding block, and the anode guide rod and the crossbeam of the anode steel claw are welded together by transition welding of the steel-aluminum explosion welding block. The anode steel claw usually includes a steel claw beam and a plurality of claws welded to the bottom of the steel claw beam, and each claw is arranged at intervals. A carbon bowl corresponding to each claw is opened on the anode carbon block, and the claw of the anode steel claw is cast in the carbon bowl of the anode carbon block through phosphorus pig iron.

[0004] The problem existing in the actual use of the anode guide rod group in the above-mentioned prior art is that when welding the steel-aluminum explosion welding block and the anode steel claw, since electric welding can only be performed on the periphery of the contact surface between the steel-aluminum explosion welding block and the anode steel claw, the welding area is small, which in turn leads to a large voltage drop, low conductivity efficiency and low welding strength.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0029] Reference Figure 1-Figure 4 The embodiment 1 of the high-conductivity anode guide rod group provided in the present application comprises an anode steel claw, an anode guide rod 1 and a steel-aluminum composite connector 2, wherein the steel-aluminum composite connector 2 connects the anode steel claw to the anode guide rod 1. The steel-aluminum composite connector 2 comprises a plurality of stacked and closely arranged steel-aluminum composite sheets, wherein the steel-aluminum composite sheet comprises a steel sheet 21 and an aluminum sheet 22 closely composited together. In the present embodiment, the thickness of the steel-aluminum composite sheet is 4-6 mm.

[0030] Continue to refer to Figure 1-Figure 4 The steel-aluminum composite connector 2 has a crossbeam 23 and a steel claw connection 24. Two steel claw connections 24 are provided and are respectively located at the two ends of the crossbeam 23. The steel claw connection 24 is connected to the lower side of the crossbeam 23. The bottom surface of the anode guide rod 1 is welded to the aluminum surface portion of the upper surface of the crossbeam 23. The anode steel claw includes four independent steel claw heads 3, and a steel claw head 3 is welded to the left and right sides of each steel claw connection 24. The steel claw head 3 includes a steel connection part 31 and a carbon block connection part 32. The upper surface of the carbon block connection part 32 is connected to the bottom surface of the steel connection part 31. The cross section of the steel connection part 31 is rectangular, and the cross section of the carbon block connection part 32 is circular. The side of the steel connection part 31 is welded to the steel surface portion of the side of the steel claw connection part 24, and the steel surface portion of the bottom surface of the crossbeam 23 is welded to the upper surface of the steel connection part 31 located below it. The carbon block connection part 32 is used to connect to the anode carbon block.

[0031] The method used when using the steel-aluminum composite sheet to connect the anode guide rod 1 and the anode steel claw is as follows: first, the steel claw heads 3 of the anode steel claw are evenly spaced and fixed in a row at the welding area, and then the steel-aluminum composite sheets are welded to the steel connecting parts 31 of the steel claw heads 3 in sequence at the welding area, and the steel claw heads 3 are connected into a whole through the steel-aluminum composite sheet.

[0032] The implementation principle of the high-conductivity anode guide rod group of Example 1 of the present application is as follows: First, the steel-aluminum composite connector 2 includes a plurality of steel-aluminum composite sheets stacked and closely arranged. When the steel-aluminum composite sheets are used to weld the anode guide rod 1 and the anode steel claw, the overall thickness of the steel-aluminum composite sheet is relatively small, and the thickness of each sheet is 4-6 mm. When used, a certain number of steel-aluminum composite sheets can be stacked according to the size of the anode guide rod 1 and the steel connection portion 31 of the steel claw head 3 so that the anode guide rod 1 and each steel claw head 3 can be firmly connected. Since the overall thickness of the steel-aluminum composite sheet is relatively small, and each sheet is welded separately, it can ensure that the steel-aluminum composite sheet is fully welded to the steel claw head 3, and the steel-aluminum composite connector 2 and the anode guide rod 1 and the anode steel claw have a large welding area, so that the actual contact area between the anode guide rod 1 and the anode steel claw is increased, which can not only reduce the voltage drop between the anode guide rod 1 and the anode steel claw, but also improve the connection strength between the anode guide rod 1 and the anode steel claw.

[0033] Secondly, the side of the steel claw head 3 is welded to the steel surface portion of the side of the steel claw connecting part 24. Since the steel claw connecting part 24 includes an aluminum sheet and a steel sheet, the conductive efficiency of the steel claw connecting part 24 is greater than that of steel, which can reduce the voltage drop during conduction; in addition, the steel surface portion of the bottom surface of the beam portion 23 is welded to the upper surface of the steel claw head 3 located therebelow, and the side of the steel claw head 3 is welded to the steel surface portion of the side of the steel claw connecting part 24, which can increase the welding area between the steel claw head 3 and the beam portion 23, thereby reducing the voltage drop and increasing the welding strength.

[0034] On the third aspect, the steel claw head 3 is set as a characteristic structure combining a cuboid and a cylinder, and the upper end face of the cuboid of the steel claw head 3 can be better welded with the lower end face of the steel-aluminum composite connector 2, thereby enhancing the connection strength and making it easier to connect the steel claw head 3 to the anode carbon block. On the fourth aspect, by using a steel-aluminum composite sheet, each steel claw head 3 in the anode steel claw can exist independently, and the structure of the steel claw head 3 is much simpler than that of the anode steel claw in the prior art, making later fine processing more convenient and reducing the processing difficulty.

[0035] Reference Figure 5 and Figure 6 The difference between the embodiment 2 of the high-conductivity anode guide rod group provided by the present application and the embodiment 1 is that three steel claw connection parts 24 are arranged at intervals and located between the two ends of the cross beam part 23, and a deformation seam 241 extending from bottom to top is provided on the bottom surface of the steel claw connection part 24 located in the middle among the three steel claw connection parts 24. The setting of the deformation seam 241 can provide a certain stress deformation space for the steel-aluminum composite connector 2 when it expands due to heat during conduction, thereby preventing the steel-aluminum composite connector 2 from deforming to a certain extent.

[0036] Reference Figure 7The difference between the embodiment 3 of the high-conductivity anode guide rod group provided by the present application and the above-mentioned embodiment 2 is that a mounting groove 231 is provided on the upper surface of the cross beam portion 23, the bottom end of the anode guide rod 1 is inserted into the mounting groove 231, and the groove wall of the mounting groove 231 is welded to the corresponding side of the anode guide rod 1. By inserting the anode guide rod 1 into the mounting groove 231 and welding the groove wall of the mounting groove 231 to the corresponding side of the anode guide rod 1, the welding area of ​​the anode guide rod 1 can be increased, thereby further improving the conduction efficiency, reducing the voltage drop, and improving the welding strength.
