Description

Technical Field

[0001] This utility model relates to the field of high-temperature furnace technology, specifically a copper electrode cooling device for a high-temperature furnace. Background Technology

[0002] In industries such as metallurgy and materials preparation, high-temperature furnaces are core equipment for achieving high-temperature reactions and material melting processes, with operating temperatures typically reaching hundreds or even thousands of degrees Celsius. Copper electrodes, as key conductive components of high-temperature furnaces, directly participate in the conversion of electrical and thermal energy. During continuous operation, they generate a large amount of heat due to the Joule effect and radiation from the high-temperature environment. If heat cannot be dissipated effectively and promptly, the electrode temperature will rise sharply.

[0003] Currently, the cooling of copper electrodes in high-temperature furnaces mostly relies on simple water-cooled sleeve structures. This involves passing cooling water through single or double-layer pipes surrounding the electrode, using the water flow to carry away heat. However, these traditional cooling devices have significant limitations. The inner walls of the cooling pipes are mostly smooth, resulting in a limited contact area between the cooling water and the pipes, leading to low heat exchange efficiency. This makes it difficult to meet the heat dissipation requirements of high-power, high-temperature furnaces, often resulting in localized overheating of the electrodes. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-2 This embodiment of a high-temperature furnace copper electrode cooling device increases the contact area between the coolant and the outer tube 1 and the inner tube 2, thereby effectively removing the heat generated by the copper electrode during operation in the high-temperature furnace, ensuring stable operation of the electrode, and extending its service life. It is suitable for copper electrode cooling scenarios in various high-temperature furnaces.

[0016] Specifically, it includes an outer pipe 1, an inner pipe 2, an inlet pipe 5, a drain pipe 7, and an end cap 8.

[0017] In detail, both the outer tube 1 and the inner tube 2 are made of brass. The inner tube 2 is installed vertically inside the outer tube 1 and the two are coaxially arranged. A cooling cavity is reserved between the inner tube 2 and the inner circumferential wall of the outer tube 1. This cavity is the main area where the coolant flows and heat exchange occurs.

[0018] Furthermore, several annular grooves 3 are provided on the opposite side of the outer tube 1 and the inner tube 2. The annular grooves 3 are arranged at equal intervals and are coaxial with the axial line of the inner tube 2. At the same time, several vertical grooves 4 are also provided on the opposite side. The vertical grooves 4 are arranged in a ring array on the inner peripheral wall of the outer tube 1 and the outer peripheral wall of the inner tube 2. The vertical grooves 4 and the annular grooves 3 are intersected to form a grid-like structure.

[0019] Furthermore, an inlet pipe 5 is connected to the outer side of the outer pipe 1 near its bottom end. The inlet pipe 5 is connected to the cooling cavity and is used to deliver coolant into the cooling cavity. Several drain holes 6 are opened on the inner peripheral wall of the inner pipe 2 near its top end. A drain pipe 7 is connected to the inner bottom wall of the inner pipe 2. The drain pipe 7 is connected to the inside of the inner pipe 2 and is used to discharge the coolant after absorbing heat.

[0020] In actual setup, the outer tube 1 and the inner tube 2 are coaxially arranged to form a cooling cavity, so that the coolant can surround the outer side of the inner tube 2 and the inner side of the outer tube 1, forming an all-round heat exchange contact with the electrode, ensuring that heat can be quickly conducted from the electrode to the coolant.

[0021] Furthermore, the annular grooves 3 and vertical grooves 4 on the outer tube 1 and inner tube 2 are intersected, which increases the residence time of the coolant in the cooling cavity and makes the heat exchange more complete. The grid structure formed by the intersection of the two increases the contact area between the coolant and the tube wall, thereby enabling the transmitted coolant to effectively conduct heat with the outer tube 1 and inner tube 2.

[0022] In actual use, the water inlet pipe 5 connects the bottom end of the outer pipe 1 to the cooling cavity. After the coolant enters from the bottom, it can flow upward along the cooling cavity under pressure and gradually absorb heat. This upward flow direction is consistent with the upward trend of hot air. After absorbing heat, the coolant enters the inner pipe 2 through the drain hole 6 and is then discharged through the drain pipe 7, forming a complete coolant circulation path.

[0023] In addition, an end cap 8 is detachably installed on the top of the outer tube 1. The bottom end of the end cap 8 is integrally formed with a protrusion 801. The outer side of the protrusion 801 is integrally formed with an external thread. The inner circumferential wall of the inner tube 2 is provided with an internal thread that matches the external thread. The end cap 8 and the inner tube 2 are fixed by the threaded connection, thereby sealing the top of the outer tube 1 and preventing coolant from overflowing from the top.

[0024] In actual installation, the end cap 8 is connected to the inner tube 2 through the thread of the protrusion 801, which not only seals the top of the outer tube 1 to prevent coolant from overflowing, but also facilitates the removal of the end cap 8 to clean or maintain the inside of the cooling cavity.

[0025] The working principle of the above embodiments is as follows: When the high-temperature furnace is operating, the copper electrodes are inserted into the inner tube 2. The heat generated by the electrodes is conducted through the tube wall of the inner tube 2 to the coolant in the cooling cavity. The coolant enters the cooling cavity from the bottom end of the outer tube 1 through the inlet pipe 5 and flows upward along the cavity under pressure. During the flow, the coolant is guided and obstructed by the annular groove 3 and the vertical groove 4. The annular groove 3 slows down the flow speed, allowing the coolant enough time to absorb the heat transferred from the tube wall. The vertical groove 4 guides the coolant to distribute evenly along the axial direction, avoiding local accumulation. The intersecting groove structure increases the interaction between the coolant and the outer tube 1 and the inner tube. The increased contact area of ​​tube 2 enhances the heat exchange effect. After absorbing heat, the coolant continues to flow upward. When it reaches the top of the inner tube 2, it enters the inner tube 2 through the drain hole 6 and finally exits the device through the drain pipe 7 at the bottom, completing one cooling cycle. The end cap 8 seals the top of the outer tube 1 with threads to ensure that the coolant does not leak. At the same time, it maintains stable pressure in the cooling cavity, ensuring that the coolant can flow along the preset path. Through continuous coolant circulation, the heat generated by the electrode is constantly carried away, keeping the temperature of the copper electrode within a safe range and preventing the electrode performance from deteriorating or being damaged due to high temperature.
