Abstract
Description
Technical Field
[0001] This application relates to the field of graphitization technology for negative electrode materials, and more particularly to a cooling structure for a graphite electrode. Background Technology
[0002] In the traditional graphitization process, the electrodes need to be energized to generate heat. Because the electrode temperature is high, oxidation is very easy to occur. Therefore, water needs to be passed through the electrodes to cool them. However, since there are unavoidable pores in the graphite electrodes during processing or manufacturing, water can easily seep into the graphite electrodes after a period of time. The seeping water can easily cause a short circuit in the copper-aluminum busbars connected to them.
[0003] Currently, the common method is to periodically seal the gaps using graphite adhesive, but this affects production safety and stability to some extent. At the same time, because the electrodes are clamped with copper plates, the electrode cooling effect is poor, which easily causes oxidation on the outside of the electrodes. Especially when the electrodes are inserted into the furnace and exposed to the air, the high temperature causes oxidation loss and necking, affecting the service life of the electrodes. Utility Model Content

[0012] In related technologies, a common method is to periodically seal the gaps using graphite adhesive. However, this affects production safety and stability to some extent. At the same time, because the electrodes are clamped with copper plates, the electrode cooling effect is poor, which easily causes oxidation on the outside of the electrodes. Especially when the electrodes are inserted into the furnace and exposed to the air, the high temperature causes oxidation loss and necking, affecting the service life of the electrodes.
[0013] To address the technical problems existing in related technologies, this application provides a graphite electrode cooling structure. Please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic diagram of a graphite electrode cooling structure provided in an embodiment of this application. The graphite electrode cooling structure includes: a graphite electrode 1, a heat exchange tube assembly 2, an energizing plate 3, and a clamping plate 4. The heat exchange tube assembly 2 is installed inside the center of the graphite electrode 1, the energizing plate 3 is installed on the side of the graphite electrode 1 and is used to supply power, and the clamping plate 4 is installed on the side of the graphite electrode 1.
[0014] In one embodiment, when cooling the graphite electrode 1, the heat exchange tube assembly 2 is used to cool the graphite electrode 1, the energizing plate 3 is used to supply power, and the clamping plate 4 can fix the energizing plate 3 and also has the function of cooling, so as to cool the graphite electrode 1.
[0015] For example, the heat exchange tube assembly 2 is installed inside the center of the graphite electrode 1. That is, an opening is made inside the center of the graphite electrode 1, and the size of the opening matches the size of the heat exchange tube assembly 2, so that the heat exchange tube assembly 2 can be fixedly installed inside the center of the graphite electrode 1. In this way, the heat exchange tube assembly 2 can effectively remove heat from inside the graphite electrode 1, thereby significantly reducing the electrode temperature, reducing oxidation loss, and avoiding the problem of water seepage inside the electrode.
[0016] In addition, the power board 3 and the clamping plate 4 are both set on the side of the graphite electrode 1 to form a stable power connection and fixing structure, ensuring current transmission efficiency. At the same time, the cooling function of the clamping plate 4 further reduces the surface temperature of the electrode and improves the overall cooling effect.
[0017] Furthermore, the graphite electrode cooling structure also includes a connecting component 5, which is used to connect the clamping plate 4 and fix the clamping plate 4 to the side of the graphite electrode 1.
[0018] Specifically, the graphite electrode cooling structure also includes a connecting component 5, which is used to connect the clamping plate 4 so that the clamping plate 4 is fixedly disposed on the side of the graphite electrode 1, ensuring a tight fit between the clamping plate 4 and the graphite electrode 1 and enhancing the cooling effect. In addition, the connecting component 5 can be made of high-strength material to improve structural stability and prevent deformation or loosening caused by high temperature.
[0019] Furthermore, the connecting component 5 is a connecting rod.
[0020] Specifically, a connection port for fixing the connecting rod can be provided on the clamping plate 4 so that the connecting component 5 and the clamping plate 4 can be stably connected through the connecting rod and the connection port, thereby allowing the clamping plate 4 to be fixed on the side of the graphite electrode 1.
[0021] Furthermore, the clamping plate 4 includes a first clamping plate 4a and a second clamping plate 4b, and the first clamping plate 4a and the second clamping plate 4b are disposed opposite to each other on both sides of the graphite electrode 1. The connecting assembly 5 fixes the clamping plate 4 to the graphite electrode 1 by connecting the first clamping plate 4a and the second clamping plate 4b.
[0022] Specifically, the clamping plate 4 is fixedly mounted on the graphite electrode 1 using the connecting component 5. Therefore, the clamping plate 4 may include a first clamping plate 4a and a second clamping plate 4b, and the first clamping plate 4a and the second clamping plate 4b are disposed opposite to each other on both sides of the graphite electrode 1. Through the stable connection of the connecting component 5, the first clamping plate 4a and the second clamping plate 4b are ensured to be in close contact with the graphite electrode 1, forming a symmetrical cooling structure, further balancing the electrode temperature distribution, and improving the cooling efficiency of the graphite electrode 1.
[0023] Furthermore, the energizing plate 3 includes a first energizing plate 31 and a second energizing plate 32, and the first energizing plate 31 and the second energizing plate 32 are disposed opposite to each other on both sides of the graphite electrode 1.
[0024] Specifically, the power supply plate 3 is used to supply power and is located on the side of the graphite electrode. When fixing, the power supply plate 3 can be fixed by the clamping plate 4. The power supply plate 3 includes a first power supply plate 31 and a second power supply plate 32, which are arranged opposite to each other on both sides of the graphite electrode 1. Then, the first power supply plate 31 and the second power supply plate 32 are fixedly set with the graphite electrode 1 by the support of the clamping plate 4.
[0025] Furthermore, referring to Figure 2 , Figure 2 This is a cross-sectional schematic diagram of the structure of the heat exchanger tube assembly provided in an embodiment of this application. For example... Figure 2 As shown, the heat exchange tube assembly 2 includes a first inlet pipe 21, a first outlet pipe 22 and a heat exchange tube 23. One end of the first inlet pipe 21 and the first outlet pipe 22 are both located inside the heat exchange tube 23, and the size of the first inlet pipe 21 inside the heat exchange tube 23 is larger than the size of the first outlet pipe 22 inside the heat exchange tube 23.
[0026] In one embodiment, the heat exchange tube assembly 2 is disposed inside the center of the graphite electrode 1, and the graphite electrode 1 is cooled internally through heat exchange. Specifically, the heat exchange tube assembly 2 includes a first water inlet pipe 21, a first water outlet pipe 22, and a heat exchange tube 23, and one end of the first water inlet pipe 21 and the first water outlet pipe 22 are both disposed inside the heat exchange tube 23. At the same time, for the pipe size inside the heat exchange tube 23, the size of the first water inlet pipe 21 is larger than the size of the first water outlet pipe 22.
[0027] For example, the end face of the heat exchanger tube assembly 2 can be configured as follows: Figure 2 The end face structure shown is a circular end face. At the same time, an installation interface for installing the first water inlet pipe 21, the first water outlet pipe 22 and the heat exchange pipe 23 can be provided at one end of the heat exchange pipe assembly 2. The length of the first water outlet pipe 22 is greater than the length of the heat exchange pipe 23, so that the first water inlet pipe 21 has a longer pipe than the first water outlet pipe 22 and is installed in the closed space formed by the heat exchange pipe 23.
[0028] Furthermore, the first water inlet pipe 21 includes an internal pipe and an external pipe, wherein the internal pipe is located inside the heat exchange pipe 23, the external pipe is located outside the heat exchange pipe 23, and the internal pipe is provided with an opening.
[0029] Specifically, the internal pipe in the first water inlet pipe 21 is set inside the heat exchange pipe 23 to introduce cooling water into the internal space formed by the heat exchange pipe 23. At the same time, in order to make the cooling water flow more efficiently, multiple small openings can be provided on the internal pipe of the first water inlet pipe 21 to reduce the interference of cooling water in the internal space and improve the cooling effect.
[0030] It should be noted that, for the first inlet pipe 21, the first outlet pipe 22, and the heat exchange pipe 23, their cross-sectional shapes can be, in addition to the following... Figure 2 The circle shown can also be a square or other shapes; there are no specific restrictions.
[0031] Furthermore, referring to Figure 3 , Figure 3 This is a schematic diagram of a clamping plate provided in an embodiment of this application. For example... Figure 3 As shown, the clamping plate 4 is an assembly with a jacketed cooling component. The clamping plate 4 includes a housing 41, a second water inlet pipe 42, a guide plate 43, and a second water outlet pipe 44. The guide plate 43 is disposed inside the housing 41.
[0032] In one embodiment, the clamping plate 4 can cool the root of the graphite electrode 1, thus enabling the cooling water to carry away heat from the root of the graphite electrode 1. Therefore, the clamping plate 4 includes a housing 41, a second water inlet pipe 42, a guide plate 43, and a second water outlet pipe 44, wherein the guide plate 43 is disposed inside the housing 41.
[0033] Specifically, in order to achieve the cooling effect of the clamping plate 4, the clamping plate 4 includes a second water inlet pipe 42 and a second water outlet pipe 44. At the same time, for the integrity of the clamping plate 4, the clamping plate 4 also includes a housing 41 and a guide plate 43. The guide plate 43 is used to guide the cooling water injected through the second water inlet pipe 42 to the second water outlet pipe 44 for output.
[0034] Furthermore, when the clamping plate 4 is fixed, the second water inlet pipe 42 is positioned below the second water outlet pipe 44.
[0035] Specifically, when the clamping plate 4 is fixed to the graphite electrode 1, in order to improve the cooling effect, the second water inlet pipe 42 on the clamping plate 4 can be placed below the second water outlet pipe 44, which can increase the residence time of the cooling water in the internal space and improve the cooling effect.
[0036] Of course, in practical applications, the clamping plate 4 can also be set as an ordinary flat plate, that is, a flat plate without cooling treatment. In this case, the clamping plate 4 is only used to fix the power board 3. Therefore, there are no specific restrictions on the design of the clamping plate 4.
[0037] Furthermore, the energizing plate 3 and the clamping plate 4 are disposed on the same side of the graphite electrode 1, and the energizing plate 3 is disposed between the clamping plate 4 and the graphite electrode 1.
[0038] Specifically, both the energizing plate 3 and the clamping plate 4 are mounted on the side of the graphite electrode 1. As described above, when fixing the energizing plate 3, it is done simultaneously with fixing the clamping plate 4. Therefore, the energizing plate 3 and the clamping plate 4 can be located on the same side of the graphite electrode 1, with the energizing plate 3 positioned between the clamping plate 4 and the graphite electrode 1. In other words, the energizing plate 3 is first installed on one surface of the graphite electrode 1, then the clamping plate 4 is installed, and the energizing plate 3 is simultaneously fixed using the connecting assembly 5 while connecting and fixing the clamping plate 4.
[0039] In summary, this application discloses a graphite electrode cooling structure, comprising: a graphite electrode 1, a heat exchange tube assembly 2, an energizing plate 3, and a clamping plate 4. The heat exchange tube assembly 2 is installed inside the center of the graphite electrode 1, the energizing plate 3 is installed on the side of the graphite electrode 1 and is used for power supply, and the clamping plate 4 is installed on the side of the graphite electrode 1. Based on this graphite electrode cooling structure, indirect cooling can be achieved using the heat exchange tube assembly, avoiding water seepage inside the electrode. Simultaneously, the cooling treatment of the clamping plate effectively cools the electrode root, preventing oxidation of the root due to direct contact with cooling water, thus effectively improving the cooling effect of the graphite electrode.
