Description

Technical Field

[0001] The utility model belongs to the technical field of graphitization furnace electrodes, and in particular relates to a graphitization furnace electrode. Background Art

[0002] When the graphitization furnace is working, it is in a high temperature environment, so the conductive electrodes of the graphitization furnace are also in a high temperature state. Since the conductive electrodes need to be connected to the copper busbar, if the conductive electrodes are not cooled, on the one hand, the conductive electrodes may be oxidized, and on the other hand, the copper busbar may be melted.

[0003] At present, the most commonly used conductive electrode cooling method is to process a cooling cavity on the conductive electrode, and use a sealing part to seal the cooling cavity. The sealing part is provided with a water inlet pipe and a water outlet pipe. The water inlet pipe inputs coolant into the cooling cavity, and the water outlet pipe discharges the coolant.

[0004] The disadvantage of the current structure is that the cooling structure is complex to process and requires high processing precision. For example, the plugging part and the conductive electrode need to have high matching precision to ensure that the plugging part has a good sealing effect. For another example, the water inlet pipe and the water outlet pipe also need to have good matching precision with the plugging part to reduce the risk of coolant leakage. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0022] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0023] The embodiment of the present application provides a graphitization furnace electrode, including an electrode body 1 and a cooling assembly. The electrode body 1 is provided with a first cooling hole 2 penetrating the side wall of the electrode body 1. The cooling assembly includes a medium channel 4 and two plugging parts 13, the plugging parts 13 are inserted at both ends of the first cooling hole 2 one by one, the plugging parts 13 are in a frustum shape, and the small diameter side of the plugging part 13 faces the first cooling hole 2. The plugging part 13 is provided with a connecting hole, and the medium channel 4 is penetrated in the first cooling hole 2 via the connecting hole. Two abutting parts 9 are provided at intervals on the peripheral wall of the medium channel 4, and the abutting parts 9 are threadedly connected to the medium channel 4. The two plugging parts 13 are arranged between the two abutting parts 9. The medium channel 4 includes an input section 5 and an output section 6. The input section 5 is used to input the cooling medium into the first cooling hole 2, and the output section 6 is used to discharge the cooling medium in the first cooling hole 2.

[0024] The electrode body 1 is used to connect to the copper busbar. Its structure and working process in the graphitization furnace are well known to those skilled in the art and will not be described in detail here.

[0025] The blocking portions 13 are inserted at both ends of the first cooling hole 2 so that both ends of the first cooling hole 2 can be blocked, and the first cooling hole 2 forms a closed chamber to prevent the cooling medium from flowing out.

[0026] The plugging portion 13 is in a frustum shape, and the small diameter side of the plugging portion 13 faces the first cooling hole 2. On the one hand, the contact area between the plugging portion 13 and the inner wall of the first cooling hole 2 is increased, thereby increasing the sealing effect. On the other hand, the machining accuracy requirements for the plugging portion 13 and the first cooling hole 2 are reduced. Even if there is an error in the aperture of the first cooling hole 2, by adjusting the depth of the plugging portion 13 inserted into the first cooling hole 2, the plugging portion 13 can still close the first cooling hole 2, thereby ensuring the sealing effect.

[0027] In the embodiment of the present application, the inner wall of the first cooling hole 2 and the blocking portion 13 may also be in a frustum shape.

[0028] The input section 5 of the medium channel 4 inputs the cooling medium into the first cooling hole 2 , and the output section 6 discharges the cooling medium, so that the electrode body 1 can be cooled down through the first cooling hole 2 .

[0029] The abutment portion 9 is threadedly connected to the medium channel 4 , so that the abutment portion 9 can be rotated to move the abutment portion 9 along the axial direction of the medium channel 4 , thereby enabling the two abutment portions 9 to clamp the blocking portion 13 , thereby increasing the sealing effect of the blocking portion 13 .

[0030] Furthermore, the abutment portion 9 reduces the machining accuracy requirements for the connecting hole of the sealing portion 13, that is, the abutment portion 9 and the medium channel 4 are connected via a threaded connection and have good sealing performance. When the abutment portion 9 abuts against the sealing portion 13, even if there is an error between the tube diameter of the medium channel 4 and the aperture of the connecting hole, the abutment portion 9 can still seal the gap between the medium channel 4 and the connecting hole to ensure the sealing effect.

[0031] Furthermore, the abutting portion 9 also plays a role in adjusting the position of the medium channel 4 , that is, by adjusting the axial position of the abutting portion 9 in the medium channel 4 , the position of the medium channel 4 when fixed to the blocking portion 13 can be adjusted.

[0032] In the embodiment of the present application, a seal may be provided on the side of the abutment portion 9 facing the blocking portion 13 to increase the sealing effect. The specific material of the seal may be selected from existing products and will not be described in detail here.

[0033] In some embodiments, a partition is provided inside the medium channel 4 , which divides the medium channel 4 into an input section 5 and an output section 5 , an outlet 8 is provided on the peripheral wall surface of the input section 5 , and an inlet 7 is provided on the peripheral wall surface of the output section 6 .

[0034] The partition can separate the medium channel 4, so that the medium channel 4 can play the role of inputting the cooling medium and outputting the cooling medium. Compared with the traditional method of setting two pipelines, the cost is saved.

[0035] The inlet 7 of the input section 5 and the outlet 8 of the output section 6 are respectively arranged in the first cooling holes 2 .

[0036] After the cooling medium enters the input section 5, it enters the first cooling hole 2 from the outlet 8 of the input section 5, cooling the electrode body 1. Then, the cooling medium enters the output section 6 from the inlet 7 of the output section 6 and is discharged through the output section 6, so that the cooling medium can circulate.

[0037] In some embodiments, the outlet 8 and the inlet 7 are provided in plurality.

[0038] The outlet 8 of the input section 5 and the inlet 7 of the output section 6 are provided in multiple numbers, which increases the flow rate of the cooling medium and reduces the risk of reduced cooling effect due to too small flow rate of the cooling medium.

[0039] In some embodiments, a plurality of outlets 8 are arranged around the circumference of the input section 5 , and a plurality of inlets 7 are arranged around the circumference of the output section 6 .

[0040] A plurality of outlets 8 are arranged around the circumference of the input section 5 so that the cooling medium can be injected into the first cooling hole 2 from multiple directions, so that the cooling medium is dispersed more evenly and the cooling effect is improved.

[0041] Similarly, multiple inlets 7 are arranged around the circumference of the output section 6, so that the cooling medium can enter the output section 6 from multiple directions, making the flow of the cooling medium more uniform and improving the cooling effect.

[0042] In some embodiments, a plurality of outlets 8 are arranged at intervals along the axial direction of the input section 5 .

[0043] Since the medium channel 4 passes through the first cooling hole 2 and the multiple outlets 8 are arranged at intervals along the axial direction of the input section 5, the cooling medium can be input from different axial positions of the first cooling hole 2, so that the low-temperature cooling medium can diffuse more quickly in the first cooling hole 2, thereby increasing the cooling effect.

[0044] In some embodiments, the electrode body 1 is provided with a second cooling hole 3 , and a port of the second cooling hole 3 passes through a side wall surface of the first cooling hole 2 .

[0045] Since the first cooling hole 2 penetrates the side wall surface of the electrode body 1 , compared with the traditional axial cooling hole, the axial length of the first cooling hole 2 is smaller, and the cooling effect may not meet the requirements.

[0046] By providing the second cooling hole 3 , the volume of the cooling medium that can be accommodated in the electrode body 1 is increased, thereby ensuring the cooling effect on the electrode body 1 .

[0047] The port of the second cooling hole 3 passes through the side wall of the first cooling hole 2. On the one hand, by blocking the first cooling hole 2, the first cooling hole 2 and the second cooling hole 3 can be blocked at the same time, thereby improving the work efficiency. On the other hand, it is convenient to process the second cooling hole 3, that is, after the first cooling hole 2 is processed, a drilling device can be used to drill from the side wall of the first cooling hole 2 to process the second cooling hole 3.

[0048] In some embodiments, the axial angle between the first cooling hole 2 and the axial angle between the second cooling hole 3 is less than 90°.

[0049] The advantage of such a setting is that it makes the processing of the second cooling hole 3 more convenient. If the axial angle between the second cooling hole 3 and the first cooling hole 2 is equal to 90°, the drill bit of the drilling equipment cannot process the second cooling hole 3 from the first cooling hole 2. The axial angle between the first cooling hole 2 and the second cooling hole 3 is less than 90°, so that the drill bit of the drilling equipment can tilt into the first cooling hole 2 to process the second cooling hole 3.

[0050] In some embodiments, a deep channel 12 is provided at the inlet 7 of the output section 6 , and the deep channel 12 is inserted into the second cooling hole 3 .

[0051] The deep channel 12 penetrates into the second cooling hole 3, so that the high-temperature cooling medium in the second cooling hole 3 can be discharged through the deep channel 12, which facilitates the flow replacement of the cooling channel.

[0052] In some embodiments, a recessed portion 10 is provided on the large diameter side of the blocking portion 13 , and the port of the connecting hole located on the large diameter side is accommodated in the recessed portion 10 .

[0053] On one hand, the recessed portion 10 reduces the weight of the blocking portion 13 and saves the cost. On the other hand, the recessed portion 10 can protect the medium channel 4 .

[0054] In some embodiments, a spiral channel 11 is further included. The spiral channel 11 is arranged around the circumference of the electrode body 1 , and the spiral channel 11 is connected to the output section 6 .

[0055] Since the first cooling holes 2 and the second cooling holes 3 can accommodate a large amount of cooling medium, the cooling medium discharged from the output section 6 can be reused to further cool the motor body.

[0056] The spiral channel 11 is arranged around the circumference of the electrode body 1, so that the cooling medium entering the spiral channel 11 can further cool the motor body, thereby improving the cooling effect.

[0057] The spiral channel 11 can be made of metal. The specific material can be selected from existing metals and will not be described in detail here.

[0058] The above embodiments are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made by ordinary technicians in this field to the technical solutions of the present invention should all fall within the protection scope determined by the claims of the present invention.
