Description

Technical Field

[0001] This utility model relates to the field of metal smelting, and more specifically, it relates to a heat dissipation cathode suspension rod. Background Technology

[0002] In the electrolytic metallurgical industry, the cathode suspension rod, as the core conductive component of the electrolytic cell, performs the dual functions of transmitting current and supporting the cathode. Traditional cathode suspension rods are mostly made of solid copper or copper alloys. While these materials possess excellent conductivity, in practical applications, the large current flowing through the suspension rod generates significant Joule heating. Simultaneously, the high-temperature environment within the electrolytic cell further exacerbates heat accumulation, leading to a rapid increase in the suspension rod's temperature. This high temperature accelerates material oxidation, increases contact resistance, and creates a vicious cycle.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heat dissipation cathode suspension rod.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a heat dissipation cathode suspension rod, comprising a conductive body, the conductive body being cylindrical, wherein a plurality of air inlet pipes and corresponding air outlet pipes are disposed through the conductive body, the air inlet pipes and air outlet pipes being detachably connected to the conductive body in a sliding manner, the outer walls of the air inlet pipes and air outlet pipes being in contact with the inner wall of the conductive body, one air inlet pipe corresponding to one air outlet pipe, one end of the air inlet pipe being connected to one end of the air outlet pipe through a bend pipe, all the bend pipes being located on the same side of the conductive body, and the ends of the air inlet pipes away from the bend pipes and the ends of the air outlet pipes away from the bend pipes being detachably connected to connecting pipes, the other end of the connecting pipes being detachably connected to a gas pipe for transmitting gas.

[0006] The present invention is further configured such that: the number of air outlet pipes and the number of air inlet pipes are both two, the air inlet pipes and the air outlet pipes are arranged in a circular array around the axis of the conductor, and the air inlet pipes and the air outlet pipes are spaced apart in the circular array.

[0007] The present invention is further configured such that the bent pipe, the air inlet pipe, and the air outlet pipe are integrally formed.

[0008] The present invention is further configured such that: the conductor is covered with an anti-corrosion sleeve, and one end of the anti-corrosion sleeve is detachably connected to a cover plate that seals the bent pipe inside.

[0009] The present invention is further configured such that both the air inlet pipe and the air outlet pipe are made of titanium tubes with micropores on their surface.

[0010] The present invention is further configured such that the conductor is a copper-silver alloy.

[0011] In summary, this utility model has the following advantages: First, the use of gas medium for heat dissipation achieves low-cost temperature control of the suspension rod; second, the modular and detachable pipe design greatly improves maintenance convenience; and finally, the optimized combination of titanium alloy pipe and copper-silver conductor takes into account multiple requirements of conductivity, heat dissipation and corrosion resistance.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Example: A heat dissipation cathode suspension rod, such as Figure 1 , Figure 2 As shown, the conductor 1 is made of a cylindrical copper-silver alloy, which ensures high conductivity while possessing good high-temperature strength. Several sets of airflow channels are axially integrated within the conductor 1, each set consisting of an inlet pipe 2 and a corresponding outlet pipe 3. These pipes are made of sintered titanium powder with high thermal conductivity and corrosion resistance; the surface of the sintered powder pipe has micropores to enhance heat exchange efficiency. The inlet pipe 2 and outlet pipe 3 form a U-shaped connection at one end of the conductor 1 via a bend pipe 4, allowing the cooling gas to form a complete circulation path within the pipes. The integrally molded structure also provides good structural stability. This independent airflow system prevents the conductor 1 from directly contacting the external airflow; instead, it exchanges heat indirectly through the inlet pipe 2 and outlet pipe 3, slowing down the oxidation of the conductor 1.

[0017] like Figure 2 As shown, the airflow duct system adopts a modular design, with all duct components installed detachably within the conductor 1. Specifically, the inlet pipe 2 and outlet pipe 3 are connected to the inner wall of the conductor 1 via a sliding fit structure, ensuring good heat conduction contact and facilitating replacement of the airflow duct by pulling out the inlet pipe 2 and outlet pipe 3 during later maintenance. At one end of the conductor 1, all the bends 4 are centrally arranged in the same area. This layout not only saves space but also facilitates the replacement of the inlet pipe 2 and outlet pipe 3.

[0018] like Figure 2 As shown, in practical applications, the preferred embodiment employs a symmetrical pipe arrangement with two inlets and two outlets. Two inlet pipes 2 and two outlet pipes 3 are evenly spaced along the circumference of the conductor 1; this array-like distribution achieves a more uniform heat dissipation effect. The inlet pipes 2 and outlet pipes 3 are connected by an integrally formed bent pipe 4, eliminating the leakage risk that may exist with traditional welded joints.

[0019] like Figure 2 As shown, regarding the external airflow connection, each inlet pipe 2 and outlet pipe 3 has a connecting pipe 5 at its port for connecting to an external air supply system. Cooling gas flows in from the inlet pipe 2, is redirected by the bend pipe 4, and then exits from the outlet pipe 3, forming a reasonable airflow path. During the flow of the gas through the pipe, it undergoes efficient heat exchange with the conductor 1 through the titanium pipe wall, continuously carrying away the heat accumulated inside the conductor 1. The microporous structure on the pipe surface further increases the heat exchange area and improves the heat dissipation efficiency.

[0020] like Figure 1 , Figure 2 As shown, to enhance the overall protective performance of the structure, an anti-corrosion sleeve 6 is fitted around the conductor 1. The anti-corrosion sleeve 6 is made of high-temperature resistant ceramic matrix composite material, which can effectively isolate the corrosive medium of the electrolytic environment. One end of the anti-corrosion sleeve 6 is connected to a removable cover plate 7 through a threaded connection, which completely seals and protects the area of ​​the bent pipe 4, while also facilitating the extension of the service life of the bent pipe 4.

[0021] During operation, cooling gas is driven by an external fan and enters the inlet pipe 2 at a certain pressure. As the gas flows through the pipe, it carries away the heat generated by the conductor 1. Since the cooling medium is only air, and the pipeline through which the cooling medium flows is independent, the gas discharged from the outlet pipe 3 can be directly released. By adjusting the gas flow rate and pressure, the heat dissipation intensity can be precisely controlled, keeping the suspension rod within its optimal operating temperature range. This solution has significant advantages over traditional water-cooling systems, completely avoiding the risk of liquid leakage and having lower requirements for the cooling medium; ordinary compressed air is sufficient.

[0022] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
