Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic aluminum, and more specifically, to a connection structure for the cathode steel rod of an electrolytic cell. Background Technology

[0002] Aluminum electrolysis production technology has developed rapidly, with continuously improving production efficiency and expanding production scale. The cell type has evolved from the initial self-baking cells to the current prebaked cells. In early designs of prebaked electrolytic cells, the cathode steel rod and cathode flexible mother tape were connected by a crimping method for conductivity. Furthermore, the cathode steel rod head required milling and drilling, making the process cumbersome and the crimping method outdated. Cradle frames on both sides of the steel rod limited the operating space, hindering construction and resulting in low work efficiency. Specifically, the flexible mother tape needed to be connected to the end of the steel rod, but the end of the steel rod was not completely exposed; cradle frames were installed around the end, severely restricting the operating space during connection operations. Moreover, the connection required passing the screw through the flexible mother tape and then through the end of the steel rod (the screw's axis was perpendicular to the length of the steel rod), further complicating the already confined space. Therefore, connecting the flexible mother tape to the steel rod was a labor-intensive and time-consuming operation. Thus, a more efficient connection method is needed. Utility Model Content

[0003] The purpose of this invention is to provide a connection structure for the cathode steel rod of an electrolytic cell, which can efficiently connect the soft mother tape and the cathode steel rod, thereby improving the connection efficiency.

[0004] This utility model is achieved through the following technical solution: The electrolytic cell cathode steel rod connection structure of this utility model includes a steel rod, a pair of L-shaped connecting plates, a soft female strip provided on one of the outer side walls of the connecting plates, a connecting hole opened on the side of the connecting plate without the soft female strip, a connecting rod, and a pair of nuts respectively threaded to both ends of the connecting rod; the pair of connecting plates are symmetrically arranged, and the side of the pair of connecting plates with the connecting hole is respectively attached to the opposite sides of the end of the steel rod, the connecting rod is provided through the pair of connecting holes, and the nuts abut against the side walls of the connecting plates.

[0005] Furthermore, the end of the steel rod is provided with an elongated groove, which is a through structure, and the connecting rod is engaged in the groove.

[0006] Furthermore, the steel rod end is provided with a pair of slots, which are parallel to each other; the connecting plate is provided with a pair of connecting holes, and the connecting rod is provided with a pair; the pair of connecting rods are simultaneously inserted into the pair of connecting holes; the pair of connecting rods are respectively locked in the pair of slots.

[0007] Furthermore, a gap is provided between the pair of connecting plates.

[0008] Furthermore, the flexible mother tape and the connecting plate are connected by welding.

[0009] Furthermore, the inner wall of the side of the connecting plate connected to the soft mother tape abuts against the end of the steel rod.

[0010] The technical solution of this utility model has at least the following advantages and beneficial effects: In the electrolytic cell cathode steel rod connection structure of this utility model, when in use, the connecting rod is first inserted into the connecting holes of a pair of connecting plates, and then moved along the length of the steel rod to clamp the pair of connecting plates on both sides of the steel rod. Finally, nuts are screwed into both ends of the connecting rod to connect the connecting plates and the soft mother tape to the steel rod.

[0015] Example

[0016] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 -Appendix Figure 3As shown, the electrolytic cell cathode steel rod connection structure of this embodiment includes a steel rod 1, a pair of L-shaped connecting plates 3, a flexible female strip 4 disposed on one of the outer side walls of the connecting plates 3, connecting holes 5 opened on the side of the connecting plates 3 without the flexible female strip 4, a connecting rod 6, and a pair of nuts 7 respectively threaded to both ends of the connecting rod 6; the pair of connecting plates 3 are symmetrically arranged, with the sides of the pair of connecting plates 3 having the connecting holes 5 respectively attached to the opposite sides of the end of the steel rod 1, the connecting rod 6 passing through the pair of connecting holes 5, and the nuts 7 abutting against the side walls of the connecting plates 3. Specifically, in use, the connecting rod 6 is first inserted into the connecting holes 5 of the pair of connecting plates 3, and then moved along the length of the steel rod 1 to clamp the pair of connecting plates 3 onto the two side walls of the steel rod 1. Finally, the nuts 7 are screwed into both ends of the connecting rod 6 to connect the connecting plates 3 and the flexible female strip 4 to the steel rod 1. This eliminates the need to insert the nuts 7 along the end of the steel rod 1, making the operation more convenient and efficient, effectively shortening the working time, and making subsequent disassembly more convenient.

[0017] In this embodiment, the end of the steel rod 1 is provided with a long strip-shaped groove 2, which is a through structure, and the connecting rod 6 is engaged in the groove 2. Specifically, this allows the connecting plate 3 to fit more closely to the steel rod 1, and the connecting rod 6 to be located inside the steel rod 1, so that the clamping force of the nut 7 on the connecting plate 3 can be better applied to the steel rod 1, resulting in a larger and more stable contact area between the connecting plate 3 and the steel rod 1.

[0018] In this embodiment, the steel rod 1 has a pair of slots 2 at its end, which are parallel to each other; the connecting plate 3 has a pair of connecting holes 5, and a pair of connecting rods 6 are provided; the pair of connecting rods 6 are simultaneously inserted into the pair of connecting holes 5; the pair of connecting rods 6 are respectively locked into the pair of slots 2. Specifically, the pair of slots 2 and the pair of connecting rods 6 can make the fixing of the connecting plate 3 more stable, the connection between the connecting plate 3 and the steel rod 1 tighter, and less prone to loosening.

[0019] In this embodiment, a gap is provided between the pair of connecting plates 3. Specifically, this prevents the pair of connecting plates 3 from generating any force, thus not affecting the fixing of the connecting plates 3 by the nut 7, and allowing the connecting plates 3 to fit better against the side wall of the steel rod 1.

[0020] In this embodiment, the soft mother tape 4 and the connecting plate 3 are connected by welding.

[0021] In this embodiment, the inner wall of the connecting plate 3 connected to the flexible female tape 4 abuts against the end of the steel rod 1. Specifically, this is to increase the contact area between the connecting plate 3 and the steel rod 1.

[0022] In summary, the electrolytic cell cathode steel rod connection structure of this embodiment allows for the following steps: First, the connecting rod 6 is inserted into the connecting holes 5 of a pair of connecting plates 3. Then, it is moved along the length of the steel rod 1 to clamp the pair of connecting plates 3 onto the two side walls of the steel rod 1. Finally, nuts 7 are screwed into both ends of the connecting rod 6 to connect the connecting plates 3 and the flexible strap 4 to the steel rod 1. This eliminates the need to insert nuts 7 into the ends of the steel rod 1, making the operation more convenient and efficient, effectively shortening the working time, and making subsequent disassembly more convenient.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
