Description

Technical Field

[0001] This utility model relates to electrode rod technology, and more specifically, to copper electrolytic cathode suspension rods. Background Technology

[0002] When electrolyzing copper, stainless steel cathode suspension rods are typically used. The stainless steel cathode suspension rod consists of a conductive core rod and a stainless steel outer shell that is fitted over the conductive core rod. Copper contact points are set at both ends of the conductive core rod, and copper contact plates are set at both ends of the stainless steel outer shell. In order to keep the suspension rod stable and in the electrolyte for a long time, hanging lugs are usually set on the suspension rod for suspension support.

[0003] Most existing hanging lugs are fixed to the suspension rod by welding. Since the suspension rod is immersed in electrolyte for a long time, the connection between the hanging lug and the suspension rod is prone to corrosion, which affects the stability of the suspension rod.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a copper electrolysis cathode suspension rod.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a copper electrolytic cathode suspension rod, including a shell, a conductive core rod and a hanging ear, a connecting seat is provided on the side wall of the shell, a circular cavity is opened in the connecting seat, a slot communicating with the circular cavity is opened on the top surface of the connecting seat, the hanging ear includes a horizontal frame and a hook fixed on the horizontal frame, the horizontal frame can pass through the slot and be stored in the circular cavity, and a limiting block is provided on the hook to prevent the horizontal frame from falling out of the circular cavity.

[0007] The present invention is further configured such that: the upper side wall of the circular cavity is provided with a groove for embedding the horizontal frame, the limiting block is threadedly connected to the hook frame, and the limiting block is used to press the horizontal frame against the top wall of the groove.

[0008] The present invention is further configured such that the projected area of ​​the limiting block on the connecting seat is equal to the cross-sectional area of ​​the connecting seat.

[0009] The present invention is further configured such that: the top surface of the limiting block is provided with an inclined groove, and a sealing element is provided in the inclined groove.

[0010] The present invention is further configured such that a friction groove is formed on the outer peripheral wall of the limiting block.

[0011] The present invention is further configured such that the thickness of the horizontal frame is equal to the depth of the circular cavity.

[0012] In summary, this utility model has the following beneficial effects:

[0013] The horizontal frame is housed within the circular cavity, preventing the electrolyte from directly contacting it. This reduces the likelihood of corrosion of the hanging ears due to prolonged contact with the electrolyte, while ensuring sufficient contact area between the cathode suspension rod and the electrolyte. This improves the stability of the hanging ears in suspending the suspension rod. Furthermore, if the hanging ears are damaged due to corrosion, they can be replaced by releasing the limiting block. Compared to the existing technology where the hanging ears are fixedly connected to the suspension rod, this design makes the maintenance of the hanging ears more convenient.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Copper electrolytic cathode suspension rod, such as Figure 1 and Figure 2As shown, the device includes a housing 1, a conductive core rod 2, and a hanging lug. A connecting seat 3 is fixed to the side wall of the housing 1. A circular cavity 4 is formed in the connecting seat 3, and a slot 5 communicating with the circular cavity 4 is formed on the top surface of the connecting seat 3. The hanging lug includes a horizontal frame 6 and a hook 7 fixed on the horizontal frame 6. The horizontal frame 6 and the hook 7 are arranged perpendicular to each other. The horizontal frame 6 can pass through the slot 5 and be stored in the circular cavity 4. A limiting block 8 is provided on the hook 7 to prevent the horizontal frame 6 from falling out of the circular cavity 4. When using the cathode suspension rod, in order to increase the contact area between the cathode suspension rod and the electrolyte, the entire housing 1 is usually submerged in the electrolyte. This design allows part of the connecting seat 3 to be submerged in the electrolyte. At this time, the horizontal frame 6 is contained within the cavity 4, preventing the electrolyte from directly contacting the horizontal frame 6. This reduces the possibility of corrosion of the hanging ear due to prolonged contact with the electrolyte, while ensuring the contact area between the cathode suspension rod and the electrolyte. This improves the stability of the hanging ear in suspending the suspension rod. Additionally, when the hanging ear is damaged by corrosion, it can be replaced by releasing the limiting block 8. Compared to the existing technology where the hanging ear is fixedly connected to the suspension rod, this design makes the maintenance of the hanging ear more convenient.

[0020] like Figure 2 and Figure 3As shown, the upper sidewall of the cavity 4 has a groove 9 for embedding the horizontal frame 6. The length direction of the groove 9 is perpendicular to the length direction of the slot 5. The limiting block 8 is threadedly connected to the hook frame 7. The limiting block 8 is used to press the horizontal frame 6 against the top wall of the groove 9. Specifically, the hook frame 7 includes a straight part and a hook part. The straight part is welded to the horizontal frame 6, and the hook part is used to hang on external tools such as hooks. The straight part is fixed to the middle of the top wall of the horizontal frame 6. The outer peripheral wall of the straight part has an external thread. The middle of the limiting block 8 has a threaded hole that mates with the external thread. When installing the hanging ear, people first pass the horizontal frame 6 at the bottom of the hanging ear through the slot 5, then rotate the horizontal frame 6 and apply a force that makes the horizontal frame 6 abut against the upper sidewall of the cavity 4. When the horizontal frame 6 is embedded in the groove 9, it abuts against the top and side walls of the groove 9, preventing it from rotating further. At this point, the limiting block 8 is rotated and moved towards the top surface of the connecting seat 3, causing it to press against the top surface of the connecting seat 3. This simultaneously presses the horizontal frame 6 against the top wall of the groove 9, completing the limiting of the lug. This prevents the horizontal frame 6 from rotating within the cavity 4 during subsequent use of the cathode suspension rod, ensuring the stability of the lug in suspending the rod. The projected area of ​​the limiting block 8 on the connecting seat 3 is equal to the cross-sectional area of ​​the connecting seat 3. This design ensures that when the limiting block 8 limits the lug, it completely covers the slot 5, reducing the possibility of electrolyte leaking from the slot 5 into the cavity 4. To provide some protection, the top surface of the limiting block 8 has an inclined groove 10, which is filled with a sealing element 11. Specifically, the sealing element 11 is made of polytetrafluoroethylene (PTFE), which has good resistance to sulfuric acid, allowing it to adapt well to the working environment filled with electrolyte. After the limiting block 8 is used to restrict the hanging lug, the hot-melted sealing element 11 is filled into the inclined groove 10. After the sealing element 11 cools, it effectively fills the gap between the limiting block 8 and the hook 7, further reducing the possibility of electrolyte entering the circular cavity 4. At the same time, the cooled sealing element 11 also reduces the possibility of relative rotation between the limiting block 8 and the hook 7, ensuring to a certain extent that the hanging lug is properly secured to the suspension rod. For stability, friction grooves 12 are provided on the outer peripheral wall of the limiting block 8. The friction grooves 12 improve the surface roughness of the outer peripheral wall of the limiting block 8, reducing the possibility of relative sliding during installation or removal of the limiting block 8, thus facilitating its installation or removal. The thickness of the horizontal frame 6 is equal to the depth of the circular cavity 4. This design ensures that the horizontal frame 6 can rotate when fully embedded in the circular cavity 4, while also guaranteeing the strength of the connecting seat 3 and the connection strength between the connecting seat 3 and the suspension rod. The connecting seat 3 and the outer shell 1 are integrally formed, which effectively ensures the connection strength between the connecting seat 3 and the outer shell 1. Both the connecting seat 3 and the outer shell 1 are made of 316L stainless steel, which has excellent acid resistance.The connector 3 and housing 1, made using this material, can adapt well to working environments with long-term contact with electrolyte, thus improving the service life of the cathode suspension rod.
