Description

Technical Field

[0001] The utility model relates to the technical field of anodes of aluminum electrolysis equipment, in particular to a novel energy-saving anode guide rod assembly. Background Art

[0002] With the development of society, the requirements for reducing energy consumption in aluminum electrolysis industry are getting higher and higher. At present, reducing power consumption by reducing anode voltage drop is an important research direction. The anode guide rod assembly used in the aluminum electrolysis industry includes an aluminum anode guide rod and a steel anode claw. The anode claw is used for conducting electricity and bearing the load of the anode carbon block. The structure of the anode guide rod assembly can be found in the Chinese invention patent application with application publication number CN116926629A. The device includes an anode guide rod, an anode steel claw and a steel-aluminum connecting structure. The anode guide rod is located at the upper end of the steel-aluminum connecting structure, and the anode steel claw is located at the lower end of the steel-aluminum connecting structure. The anode guide rod and the anode steel claw are connected together through the steel-aluminum connecting structure; wherein the steel-aluminum connecting structure is a composite connecting structure, and the steel-aluminum connecting structure includes a plurality of stacked and closely arranged steel-aluminum composite sheets, and the steel-aluminum composite sheet includes a steel sheet and an aluminum sheet, and the steel sheet and the aluminum sheet are closely compounded into one, and the steel sheet has a steel claw joint for welding with the anode steel claw, and the aluminum sheet has a steel claw joint for welding with the anode steel claw. The aluminum guide rod joint of the anode guide rod is welded; during welding, the steel-aluminum composite sheet is first welded to the anode steel claw, and after the welding of one steel-aluminum composite sheet is completed, the next steel-aluminum composite sheet is immediately overlapped and welded, and each steel-aluminum composite sheet forms a steel-aluminum connection structure, and then the anode guide rod is welded to the aluminum guide rod joint of the steel-aluminum composite sheet; a certain number of steel-aluminum composite sheets are stacked according to the size of the anode guide rod, and each steel-aluminum composite sheet is stacked and arranged closely, and each steel-aluminum composite sheet is welded to the anode guide rod and the anode steel claw, and the welding area between the steel-aluminum connection structure and the anode steel claw can reach more than 90% of the contact area, which greatly reduces the resistance and contact voltage drop between the two, and reduces the production power consumption.

[0003] Anode steel claws are available in single anode form and double anode form. Single anode steel claws connect one anode carbon block, and double anode steel claws connect two anode carbon blocks. The structure of double anode steel claws can be found in a Chinese utility model patent with authorization announcement number CN218372554U, which discloses an anode steel claw. The anode steel claw includes a claw head and a crossbeam. The crossbeam is a steel beam. The crossbeam includes a main crossbeam and a secondary crossbeam. Two main crossbeams are provided. The two main crossbeams are arranged in an X-shape. Four secondary crossbeams are provided. Each of the two ends of each main crossbeam is provided with a secondary crossbeam. The two ends of the secondary crossbeam are respectively connected with claw heads. There are eight claw heads and they are arranged in two rows. Each row of claw heads has four claw heads and is connected to the same anode carbon block. A connecting block is provided at the intersection of the two main crossbeams. The connecting block is used to weld the anode guide rod. Among them, the connecting block constitutes the guide rod connecting portion provided on the crossbeam of the anode steel claw, and the end of the connecting claw head of the secondary crossbeam constitutes the claw head connecting portion provided on the crossbeam of the anode steel claw.

[0004] During the aluminum electrolysis production process, the current flows through the anode rod to the anode steel claw, and then from the tip of the anode steel claw to the anode carbon block. Using the steel-aluminum connection structure formed by the steel-aluminum composite sheet mentioned above for welding between the anode rod and the anode steel claw can reduce the voltage drop of the current flowing from the anode rod to the anode steel claw. However, for the above-mentioned double-anode steel claw, there are many claw tips, and the claw tips are relatively far from the anode rod, that is, the connecting part of the claw tips at the edge of the anode steel claw is relatively far from the connecting part of the rod at the center. After the current flows from the anode rod to the anode steel claw, it needs to flow through the parts of the main beam and the secondary beam of the anode steel claw located between the connecting part of the rod and the connecting part of the claw tip. The current-carrying path on the anode steel claw is relatively long and the electrical conductivity of the anode steel claw is relatively poor, which is not conducive to reducing the voltage drop generated when the current flows through the anode steel claw, and thus not conducive to reducing power consumption. Summary of the Invention

[0005] The purpose of the present invention is to provide a new type of energy-saving anode rod assembly to solve the problem that the current anode rod assembly is prone to a high voltage drop and thus increased power consumption when the current flows through the anode steel claw due to the relatively long distance between the claw tip and the anode rod.

[0006] The technical solution of the new type of energy-saving anode rod assembly of the present invention is as follows:

[0007] A new type of energy-saving anode rod assembly, which includes an anode rod and an anode steel claw. The anode steel claw includes a steel beam and claw tips. The steel beam is provided with a rod connecting part and a claw tip connecting part. The anode rod assembly includes a transfer steel-aluminum connection structure welded to the rod connecting part and the anode rod. The anode rod assembly further includes a drainage aluminum row. One end of the drainage aluminum row is welded to the transfer steel-aluminum connection structure, and the other end is welded with a drainage steel-aluminum connection structure to the corresponding claw tip connecting part.

[0008] Further, the anode steel claw is a double-anode steel claw, and the claw tips of the anode steel claw are provided with two rows. The drainage aluminum rows are respectively provided on the opposite sides of the transfer steel-aluminum connection structure. The claw tip connecting parts corresponding to the claw tips in the same row are electrically connected to the same drainage aluminum row through the corresponding drainage steel-aluminum connection structures.

[0009] Further, the drainage steel-aluminum connection structures are provided on both sides of the drainage aluminum row in the direction of the side-by-side arrangement of the claw tips in the same row.

[0010] Further, the steel beam includes two main beams arranged crosswise. The rod connecting part is arranged at the intersection of the two main beams. Secondary beams are respectively provided at both ends of each main beam. Claw tips are respectively provided at both ends of each secondary beam. The secondary beams constitute the claw tip connecting parts, and the drainage steel-aluminum connection structures are provided on each secondary beam.

[0011] Further, the end face of the drainage aluminum row away from the anode rod is flush with the side face of the connection part of the claw head away from the anode rod.

[0012] Further, the width of one end of the drainage aluminum row welded to the transfer steel-aluminum connection structure is smaller than the width of the end welded to the drainage steel-aluminum connection structure.

[0013] Further, one side face of the drainage aluminum row in the thickness direction contacts the steel beam.

[0014] Further, the drainage steel-aluminum connection structure is arranged on the side of the connection part of the claw head facing away from the claw head.

[0015] Further, the thickness of one end of the drainage steel-aluminum connection structure connected to the drainage aluminum row is greater than the thickness of the end away from the drainage aluminum row.

[0016] Further, both the transfer steel-aluminum connection structure and the drainage steel-aluminum connection structure include a plurality of stacked steel-aluminum composite sheets.

[0017] Beneficial effects: The present utility model is improved on the basis of the anode rod assembly in the prior art. By providing a drainage aluminum row welded to the transfer steel-aluminum connection structure, a drainage path is formed such that the drainage aluminum row is welded to the connection part of the claw head of the steel beam of the anode steel claw through the drainage steel-aluminum connection structure. After the current enters the transfer steel-aluminum connection structure from the anode rod, most of the current can directly reach the claw head of the corresponding anode steel claw through the drainage aluminum row and the drainage steel-aluminum connection structure. The drainage aluminum row with good electrical conductivity can form a drainage path with a smaller voltage drop, which is beneficial to reducing the voltage drop generated when the current flows through the steel beam of the anode steel claw, and is not easily affected by the relatively large distance between the claw head and the anode rod when the current flows through the anode steel claw to generate a high voltage drop, which is beneficial to reducing power consumption.

[0023] The novel energy-saving anode guide bar assembly of the present utility model enables most of the current to directly reach the claw head of the corresponding anode steel claw through the drainage aluminum bar and the drainage steel-aluminum connection structure. The drainage aluminum bar with good electrical conductivity can form a drainage path with a smaller voltage drop. When the current flows through the anode steel claw, it is not easily affected by the relatively long distance between the claw head and the anode guide bar to generate a high voltage drop, which is beneficial to reducing power consumption.

[0024] Embodiment 1 of the novel energy-saving anode guide bar assembly of the present utility model:

[0025] This novel energy-saving anode guide bar assembly is used in an aluminum electrolysis cell, as Figure 1 , Figure 2 , Figure 3 shown. This anode guide bar assembly includes an anode guide bar 1, a transition steel-aluminum connection structure 2, a drainage aluminum bar 3, a drainage steel-aluminum connection structure 4, and an anode steel claw 5. The anode steel claw 5 includes a steel beam and a claw head 53. The steel beam includes a main cross beam 51 and a secondary cross beam 52. On the steel beam of the anode steel claw 5, there are a guide bar connection part and a claw head connection part. The guide bar connection part is connected to the anode guide bar 1 through the transition steel-aluminum connection structure 2. The claw head connection part is connected to the corresponding claw head 53. The claw head 53 is used to connect the corresponding anode carbon block. The anode guide bar 1 is made of aluminum material, and the anode steel claw 5 is made of steel material. Both the anode guide bar 1 and the anode steel claw 5 are welded to the transition steel-aluminum connection structure 2. The drainage aluminum bar 3 is made of aluminum material. One end of the drainage aluminum bar 3 is welded to the transition steel-aluminum connection structure 2, and the other end is welded to the corresponding claw head connection part of the anode steel claw 5 with a drainage steel-aluminum connection structure 4. The drainage aluminum bar 3 and the corresponding claw head connection part of the anode steel claw 5 are connected together through the drainage steel-aluminum connection structure 4. Both the drainage aluminum bar 3 and the corresponding claw head connection part of the anode steel claw 5 are welded to the drainage steel-aluminum connection structure 4. After the current enters the transition steel-aluminum connection structure 2 from the anode guide bar, most of the current can directly reach the claw head 53 of the corresponding anode steel claw 5 through the drainage aluminum bar 3 and the drainage steel-aluminum connection structure 4, without having to pass through the part between the guide bar connection part and the claw head connection part of the anode steel claw 5. Most of the current only needs to flow through the claw head connection part when flowing through the steel beam of the anode steel claw 5 to reach the claw head 53. The drainage aluminum bar 3 with good electrical conductivity can form a drainage path with a smaller voltage drop, which is beneficial to reducing the voltage drop generated when the current flows through the steel beam of the anode steel claw 5. When the current flows through the anode steel claw 5, it is not easily affected by the relatively long distance between the claw head 53 and the anode guide bar to generate a high voltage drop, which is beneficial to reducing power consumption.

[0026] The anode steel claw 5 is a double anode steel claw 5. The steel beam of the anode steel claw 5 includes two main cross beams 51 arranged crosswise. The two main cross beams 51 are arranged in an "X" shape. The middle parts of the two main cross beams 51 in the length direction intersect. The connecting part of the guide rod of the steel beam of the anode steel claw 5 is arranged at the intersection of the two main cross beams 51. The upper side of the intersection part of the two main cross beams 51 is used to form the connecting part of the guide rod. At both ends of each main cross beam 51 in the length direction, there are secondary cross beams 52. There are four secondary cross beams 52. Two of the secondary cross beams 52 are located on the front side of the two main cross beams 51, and the other two secondary cross beams 52 are located on the rear side of the two main cross beams 51. The secondary cross beams 52 extend in the left-right direction. The two secondary cross beams 52 on the front side correspond left and right, and the two secondary cross beams 52 on the rear side correspond left and right. The corresponding side surfaces of the main cross beam 51 and the secondary cross beam 52 in the front-rear direction are connected. At both the left and right ends of each secondary cross beam 52, there are claw heads 53. The claw heads 53 are located below the secondary cross beam 52 and are arranged downward. There are eight claw heads 53 and they are arranged in two rows. That is, the claw heads 53 on the two secondary cross beams 52 on the front side form the front row of four claw heads 53, and the claw heads 53 on the two secondary cross beams 52 on the rear side form the rear row of four claw heads 53. The secondary cross beam 52 forms the connecting part of the claw heads of the steel beam of the anode steel claw 5. On the front and rear sides of the transfer steel-aluminum connection structure 2, there are drainage aluminum bars 3 respectively. The connecting parts of the claw heads corresponding to the same row of claw heads 53 are electrically connected to the same drainage aluminum bar 3 through the corresponding drainage steel-aluminum connection structures 4, which is beneficial to simplifying the connection structure and reducing welding operations.

[0027] The side-by-side direction of the claw heads 53 in the same row is the left-right direction. Drainage steel-aluminum connection structures 4 are arranged on both the left and right sides of the drainage aluminum bar 3, which is convenient for connecting each secondary cross beam 52 and is beneficial to reducing the size of the drainage steel-aluminum connection structure 4. Drainage steel-aluminum connection structures 4 are arranged on each secondary cross beam 52, which is beneficial to the uniform distribution of current. There are two drainage aluminum bars 3 in the front and rear. The front drainage aluminum bar 3 is connected to the two secondary cross beams 52 on the front side through the drainage steel-aluminum connection structures 4 on its left and right sides respectively, and the rear drainage aluminum bar 3 is connected to the two secondary cross beams 52 on the rear side through the drainage steel-aluminum connection structures 4 on its left and right sides respectively. Each secondary cross beam 52 is connected to two claw heads 53. The two claw heads 53 are electrically connected to the corresponding drainage steel-aluminum connection structure 4 through the same secondary cross beam 52, which is convenient for the arrangement of the drainage steel-aluminum connection structure 4 and is beneficial to simplifying the connection structure.

[0028] The upper end surface of the transfer steel-aluminum connection structure 2 is connected to the lower end surface of the anode guide rod 1. The lower end surface of the transfer steel-aluminum connection structure 2 is connected to the main cross beam 51. The front and rear side surfaces of the transfer steel-aluminum connection structure 2 are respectively connected to the corresponding end surfaces of the front and rear drainage aluminum bars 3. The size of the transfer steel-aluminum connection structure 2 in the left-right direction is the same as the size of the drainage aluminum bar 3 in the left-right direction. The drainage aluminum bar 3 is a rectangular block. The end surface of the drainage aluminum bar 3 far from the anode guide rod 1 is flush with the side surface of the corresponding secondary cross beam 52 far from the anode guide rod 1, which is beneficial to ensuring the extension length of the drainage aluminum bar 3 and is convenient for welding the drainage steel-aluminum connection structure 4.

[0029] On the left and right sides of the end of the drainage aluminum row 3 away from the transition steel-aluminum connection structure 2, drainage steel-aluminum connection structures 4 are respectively welded. The thickness direction of the drainage aluminum row 3 is the up-and-down direction. The lower side of the drainage aluminum row 3 contacts the upper side of the main crossbeam 51, so that the drainage aluminum row 3 abuts against the steel beam of the anode steel claw 5, with a compact structure and space saving. The width of the drainage steel-aluminum connection structure 4 in the front-back direction is the same as the width of the secondary crossbeam 52 in the front-back direction. The drainage steel-aluminum connection structure 4 is arranged on the side of the secondary crossbeam 52 facing away from the claw head 53, with a compact structure and space saving for layout. The thickness direction of the drainage steel-aluminum connection structure 4 is the up-and-down direction. The thickness of the end of the drainage steel-aluminum connection structure 4 connected to the drainage aluminum row 3 is greater than the thickness of the end away from the drainage aluminum row 3. The thickness of the drainage steel-aluminum connection structure 4 gradually decreases from the end connected to the drainage aluminum row 3 to the end away from the drainage aluminum row 3, which is beneficial to reducing the size of the drainage steel-aluminum connection structure 4 and saving costs.

[0030] Both the transition steel-aluminum connection structure 2 and the drainage steel-aluminum connection structure 4 include a plurality of stacked steel-aluminum composite sheets. The steel sheet part of the steel-aluminum composite sheet is used for welding steel, and the aluminum sheet part is used for welding aluminum. The steel-aluminum composite sheets of the transition steel-aluminum connection structure 2 are stacked in the left-right direction, and the steel-aluminum composite sheets of the drainage steel-aluminum connection structure 4 are stacked in the front-back direction. The steel-aluminum connection structure formed by the stacked plurality of steel-aluminum composite sheets is a prior art and will not be elaborated here. Using the steel-aluminum composite sheets of the steel-aluminum connection structure to weld steel and aluminum respectively is beneficial to increasing the welding area and reducing the voltage drop at the transition between steel and aluminum when the current passes through.

[0031] In other embodiments, the anode steel claw can also be in the form of a single anode. The steel beam of the anode steel claw extends in the left-right direction, and a plurality of claw heads are arranged side by side in the left-right direction on the steel beam. The anode guide rod is connected to the middle part of the steel beam in the left-right direction through the transition steel-aluminum connection structure. The part of the steel beam connected to the claw head constitutes the claw head connection part. The drainage aluminum rows are welded on the left and right sides of the transition steel-aluminum connection structure respectively. One end of the drainage aluminum row away from the transition steel-aluminum connection structure is connected to the steel beam by welding the drainage steel-aluminum connection structure. The drainage steel-aluminum connection structure is welded to the claw head connection part of the steel beam away from the anode guide rod, so that the voltage drop of the current reaching the claw head farther from the anode guide rod can be reduced by using the drainage aluminum row.

[0032] In other embodiments, the secondary crossbeams can also be in one-to-one correspondence with the drainage aluminum rows, and the two drainage aluminum rows corresponding to the two secondary crossbeams on the same side are arranged at an angle.

[0033] In other embodiments, two secondary crossbeams on the same side can also be connected to the same drainage steel-aluminum connection structure. At this time, the corresponding drainage aluminum rows are arranged between the drainage steel-aluminum connection structure and the transition steel-aluminum connection structure in the front-back direction.

[0034] In other embodiments, the thickness of the drainage steel-aluminum connection structure can also be made uniform at all positions in the left-right direction.

[0035] In other embodiments, the transition steel-aluminum connection structure can also be a structure including a steel-aluminum explosion welding block and a plurality of stacked steel-aluminum composite sheets. The anode busbar is fixedly connected to the anode steel claw through the steel-aluminum explosion welding block. Steel-aluminum composite sheets are arranged on the front and rear sides of the steel-aluminum explosion welding block respectively. The steel-aluminum composite sheets are welded to both the anode busbar and the anode steel claw, and the drainage aluminum bar is welded to the steel-aluminum composite sheet.

The anode steel claw 5 includes a steel beam and a claw head 53. The anode steel claw 5 is a double-anode steel claw 5. There are two rows of claw heads 53 in the front and rear directions. There are four claw heads 53 in each row. The claw heads 53 in the same row are used to connect the same anode carbon block 6. The anode steel claw 5 is connected to two anode carbon blocks 6. In the transition steel-aluminum connection structure 2 of the anode busbar assembly in this embodiment, the dimension in the front-rear direction at the upper end is smaller than the dimension in the front-rear direction at the lower end. The upper end surface of the transition steel-aluminum connection structure 2 is connected to the lower end surface of the anode busbar 1. The lower end surface of the transition steel-aluminum connection structure 2 is connected to the steel beam of the anode steel claw 5. The front and rear side surfaces of the upper part of the transition steel-aluminum connection structure 2 are inclined surfaces. The front and rear side surfaces of the lower part of the transition steel-aluminum connection structure 2 are flat surfaces. The front and rear side surfaces of the lower part of the transition steel-aluminum connection structure 2 are respectively connected to the corresponding end surfaces of the front and rear drainage aluminum bars 3. The drainage aluminum bar 3 is a block, and the width of the end of the drainage aluminum bar 3 welded to the transition steel-aluminum connection structure 2 is smaller than the width of the end welded to the drainage steel-aluminum connection structure 4. The width direction of the drainage aluminum bar 3 is the left-right direction, which can reduce the size of the drainage steel-aluminum connection structure 4 and save costs. The left and right side surfaces of the end of the drainage aluminum bar 3 welded to the drainage steel-aluminum connection structure 4 are both flat surfaces to facilitate welding of the drainage steel-aluminum connection structure 4.
