Description

Technical Field

[0001] The present application mainly relates to the field of graphitization technology, and in particular to a quick connection and disconnection system of a graphitization furnace, a graphitization production system, and a power transmission method. Background Art

[0002] Graphitization is an essential process in the production of artificial graphite anodes, graphite electrodes for steelmaking, and specialty graphite products. The process involves placing carbon products in a graphitization furnace and passing a high current through a specialized transformer. The current causes the carbon products and carbon resistor material in the furnace to generate heat, reaching temperatures of 2500°C. This high temperature rearranges the atomic structure of the carbon coke, forming a highly ordered graphite crystal structure. This results in graphite products with excellent electrical and thermal conductivity, self-lubrication, mechanical strength, anisotropy, and chemical stability. In industrial production, graphitization, due to its characteristics, is synonymous with high energy consumption and high pollution.

[0003] The graphitization furnace transmits electricity to the furnace through the furnace head electrode made of graphite material. The current graphitization furnace power transmission technology mainly adopts a rigid connection structure. Before and after power transmission, the nuts at the connection between the furnace head electrode and the wire are manually unscrewed to disconnect and connect. External wires are used to connect the transformer to multiple furnaces. Overall, the relevant technology has the following defects and areas that need improvement: (1) High cost, large floor space and space required. The existing technology requires welding multiple branch copper and aluminum bars from the DC busbar to the furnace head and furnace tail of each furnace. The transformer is connected to multiple furnaces, which requires a large number of aluminum bars. Not only is the cost high, but the aluminum bars also consume a lot of electricity during power transmission operation. (2) The switching time between power supply and power off is long and requires a lot of manpower; (3) There are great safety hazards. The graphitization high-temperature power supply furnace and the furnace where workers perform loading and unloading operations are concentrated in a limited space in the workshop. Workers have to perform loading and unloading operations next to the graphitization high-temperature furnace with safety hazards for a long time. (4) For furnaces that are not powered, unscrew the wire connections between the branch copper and aluminum bars and the electrode clamping mechanisms at the furnace head and furnace tail (for example, copper material), and separate them with insulating plates. The charged branch copper and aluminum bars are prone to short circuits between the branch copper and aluminum bars and the wire connections due to the accumulation of graphite dust in the workshop, or the falling of conductors in the workshop, resulting in short circuits between the branch copper and aluminum bars and the steel frame of the workshop.

[0004] In short, the power supply method for the graphitization furnace is relatively cumbersome and complicated. Therefore, whether it is a traditional fixed graphitization furnace or a movable graphitization furnace, the field urgently needs a method that can quickly and stably realize the electrical connection of the furnace body electrodes, so as to realize an effective, safe and reliable graphitization furnace head power supply solution, thereby being able to solve the problems of reducing power supply time, improving production efficiency, and solving the problems of manual wiring for power supply switching between furnaces, such as large engineering workload, long time consumption, low safety, high cost of copper and aluminum busbars, and low degree of automation.

DETAILED DESCRIPTION

[0026] To more clearly illustrate the technical solutions of the embodiments of this application, the following is a brief introduction to the drawings required for describing the embodiments. Obviously, the drawings described below are merely examples or embodiments of this application. Those skilled in the art can apply this application to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.

[0027] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0028] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0029] In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0030] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0031] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is solely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application. Furthermore, while the terms used in this application are selected from commonly known and commonly used terms, some terms mentioned in this specification may have been selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant sections of this description. Furthermore, this application should be understood not only by the actual terms used, but also by the meaning implied by each term.

[0032] It should be understood that when a component is referred to as being “on another component,” “connected to another component,” “coupled to another component,” or “contacting another component,” it can be directly on, connected to, coupled to, or contacting the other component, or intervening components may be present. In contrast, when a component is referred to as being “directly on another component,” “directly connected to,” “directly coupled to,” or “directly contacting” another component, there are no intervening components. Similarly, when a first component is referred to as being “electrically in contact with” or “electrically coupled to” a second component, an electrical path exists between the first and second components that allows current to flow. This electrical path may include capacitors, coupled inductors, and / or other components that allow current to flow, even without direct contact between the conductive components.

[0033] One embodiment of the present application provides a quick connection and disconnection system for a graphitization furnace, wherein the graphitization furnace has a first furnace head and a second furnace head relative to each other, and the first furnace head and the second furnace head respectively include one or more furnace head electrodes. The quick connection and disconnection system includes: a fixed-end connection device, suitable for connecting to the first furnace head, the fixed-end connection device includes an electrode clamp, one end of the electrode clamp is used to clamp the furnace head electrode, and the other end is used to connect to a power supply for supplying power to the graphitization furnace; a movable-end connection device, suitable for connecting to the second furnace head, the movable-end connection device includes an electrode clamp and a conductive connection structure, one end of the electrode clamp is used to clamp the furnace head electrode, and the other end is connected to the power supply through the conductive connection structure; wherein the electrode clamp includes a first conductive member located on both sides of each furnace head electrode, a pressure plate, and a first telescopic device connected to the pressure plate, and the first telescopic device is suitable for pushing the pressure plates located on both sides of the furnace head electrode after startup, thereby pushing the first conductive member to move in a direction close to the furnace head electrode, and causing the first conductive member to press the furnace head electrode from both sides. The above-mentioned quick connect and disconnect system can change the power supply mode of the bulky graphitization furnace to a more flexible and movable mode by respectively providing a fixed end connection device and a movable end connection device at the first and second furnace heads at both ends of the graphitization furnace. The electrode clamp in the fixed end connection device is suitable for clamping the furnace head electrode of the first furnace head; the electrode clamp in the movable end connection device on the other side is suitable for clamping the furnace head electrode of the second furnace head and electrically connecting the furnace head electrode of the second furnace head to the power supply through the conductive connection structure therein. In this way, the first and second furnace heads of the graphitization furnace are respectively corresponding to the fixed end and the movable end, which facilitates flexible wiring and power supply to the graphitization furnace, and provides a highly automated and stable electrode electrical connection method through the electrode clamp. The above-mentioned quick connect and disconnect system of the present application can quickly and stably realize the connection and disconnection of power supply to the furnace head electrode of the graphitization furnace, thereby improving the production safety, reliability and production efficiency of the graphitization furnace. Specifically for mobile graphitization furnaces, the above method allows the movable graphitization furnace to be docked at the fixed end, while the mobile end on the other side is flexibly electrically connected to the furnace head electrode through the mobile end connection device. Compared with the cumbersome power transmission connection devices and connection methods in the prior art, this method has a significant improvement effect. The above method can be applied to traditional fixed graphitization furnaces or mobile graphitization furnaces, and this application is not limited to this.

[0034] The following describes the quick connect and disconnect system in the above embodiment with reference to a plurality of drawings. Figure 11 A schematic diagram of the structure of a graphitization production system 30 is also shown. The graphitization production system 30 can adopt the quick connection and disconnection system proposed in any embodiment of the present application, for example, Figures 1 to 8 The fixed end connection device 10 and the mobile end connection device 20 of the quick connection and disconnection system shown in FIG. Figure 11 Applications such as Figures 1 to 8The embodiment shown is used as an example for detailed description. Specifically, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The figures respectively show an axonometric view, a cross-sectional view from a front view, a side view and a top view of the fixed end connection device 10 in the quick connection and disconnection system of the above embodiment. Figure 5 、 Figure 6 and Figure 7 and Figure 8 An axonometric view of one working position, a side view, a top view and an axonometric view of another working position of the mobile terminal connection device 20 in the quick connection and disconnection system of the above embodiment are respectively shown.

[0035] refer to Figure 11 The graphitization production system 30 includes a power supply (not shown), a graphitization furnace 31, and a quick connection and disconnection system, wherein the quick connection and disconnection system includes Figures 1 to 4 The fixed end connecting device 10 shown, and Figures 5 to 8 The movable end connection device 20 is shown. The graphitization furnace 31 has a first furnace head 311 and a second furnace head 312 opposite to each other. The first furnace head 311 and the second furnace head 312 each include one or more furnace head electrodes 300. The fixed end connection device 10 is suitable for connecting to the first furnace head 311, and the movable end connection device 20 is suitable for connecting to the second furnace head 312.

[0036] Clearer reference Figures 1 to 4 The fixed end connection device 10 includes an electrode holder 101. One end of the electrode holder 101 is used to clamp the furnace electrode 300, and the other end is used to connect to the power supply to the graphitization furnace 31. The electrode holder 101 includes a first conductive member 11 located on both sides of each furnace electrode 300, a pressure plate 12, and a first telescopic device 13 connected to the pressure plate 12. The first telescopic device 13 is suitable for pushing the pressure plates 12 located on both sides of the furnace electrode 300 after startup, thereby pushing the first conductive member 11 to move in a direction close to the furnace electrode 300, and making the first conductive member 11 refer to Figure 1 The x-direction shown compresses the furnace head electrode 300 from both sides. In different embodiments of the present application, when the electrode holder 101 is used, depending on the different characteristic parameters of the furnace head electrode 300, such as the size and position, one furnace head electrode 300 may be provided to correspond to one or more first telescopic devices 13.

[0037] according to Figures 1 to 4 The electrode holder 101 further includes a second conductive member 14, and the first conductive member 11 includes a first conductive plate 111, a second conductive plate 112, and a flexible member 113 located between the first conductive plate 111 and the second conductive plate 112, wherein the first conductive plate 111 is used to move along the Figure 1The furnace head electrode 300 is pressed from both sides in the x-direction shown. The second conductive plate 112 is connected to the second conductive member 14, which is used to connect to a power source. The first conductive member 11 and the second conductive member 14 are respectively made of copper or aluminum. Preferably, the first conductive member 11 is made of copper, and the second conductive member 14 is made of aluminum. That is, the first conductive plate 111 and the second conductive plate 112 are respectively copper plates, the flexible member 113 is soft copper wire, and the second conductive member 14 is an aluminum bar. Specifically, due to the lighter weight and lower cost of aluminum, in this embodiment, it is preferred to use copper for the relevant components of the first conductive member 11 that are closer to the furnace head electrode 300, taking advantage of its high-temperature resistance to better adapt to the application scenario of graphitization production. At the same time, the portion of the second conductive member 14 that requires a longer-distance conductive connection is made of aluminum, which can further save production costs.

[0038] In this embodiment, there are multiple furnace head electrodes 300, each furnace head electrode 300 is connected to an electrode holder 101, and the electrode holder 101 connected to each two or more adjacent furnace head electrodes 300 share a second conductive member 14. In this embodiment, for the graphitization furnace 31, multiple furnace head electrodes 300 are located on the masonry furnace wall where the furnace head is located, and extend from the masonry furnace wall to the outside of the wall, wherein the portion of the furnace head electrode 300 extending outside the wall is used to dock with the fixed end connection device 10 and the movable end connection device 20 proposed in this application. Figure 1 For example, multiple furnace electrodes 300 are evenly distributed in the central area of the first furnace head 311. The figure schematically shows four furnace electrodes 300. Two adjacent furnace electrodes 300 in the y-direction (vertical direction) perpendicular to the x-direction share a single second conductive member 14. This approach reduces the number of second conductive members 14 that need to interface with the first conductive member 11, thereby optimizing the layout of the second conductive members 14 and saving costs.

[0039] Continue to refer to Figure 1 The fixed end connection device 10 in this embodiment further includes a limiter 15 located on the side of the pressure plate 12 close to the first telescopic device 13. The first telescopic device 13 is adapted to allow the pressure plate 12 to drive the first conductive member 11 along the direction of the pressure plate 12 after closing. Figure 1The first conductive member is moved in the x-direction shown, away from the furnace top electrode 300, to the position where the stopper 15 is located. Once the first conductive member is in place, the electrical connection with the furnace top electrode 300 is disconnected. In one embodiment, the first retractable device 13 comprises a hydraulic device. At least one first retractable device 13, comprising a hydraulic cylinder, applies pressure to the connection surface between the furnace top electrode 300 and the first conductive plate 111 (copper plate). When the contact area is large, multiple hydraulic cylinders may be required to achieve a tight connection across all contact surfaces. The hydraulic cylinder uses the pressure of the hydraulic oil to propel the piston back and forth within the cylinder, thereby transferring mechanical energy and forming a movable conductive module. When power is supplied, hydraulic oil is injected into the oil inlet, pushing the first conductive plate 111 to connect to the furnace top electrode 300 and conduct electricity. When power is disconnected, hydraulic oil is discharged from the oil outlet, and the hydraulic cylinder retracts, moving the first conductive plate 111 and the pressure plate 12 a certain distance away from the furnace top electrode 300, for example, to the position where the stopper 15 is located.

[0040] In this embodiment, the press plate 12 preferably includes a hollow liquid-cooled press plate, which includes a liquid-cooled flow channel and a liquid inlet and outlet located at both ends of the liquid-cooled flow channel. The furnace head electrode 300 itself will generate heat under the action of electric current. In addition, the high-temperature heat in the graphitization furnace 31 is continuously discharged through the body of the furnace head electrode 300. The hollow liquid-cooled press plate removes heat by circulating a cooling liquid, such as cooling water. The cooling liquid flows from the liquid inlet of the press plate 12 into the liquid-cooled flow channel, absorbs heat from the inner wall of the liquid-cooled flow channel, and then flows out from the liquid outlet, thereby achieving the purpose of cooling the copper plate and corresponding hydraulic components in the first conductive member 11. With the above arrangement, there is no need to add an additional water cooling system, and the heat of the furnace head electrode 300 can be directly dissipated through the first conductive plate 111 electrically connected to the furnace head electrode 300.

[0041] according to Figure 1 The fixed-end connection device 10 further includes a fixed-end frame 16. The aforementioned components of the fixed-end connection device 10 are mounted on the fixed-end frame 16, which is located on the ground 100. Further preferably, the fixed-end frame 16 can be supported by insulating rollers so as to be located on the ground 100 on one side of the first furnace head 311, thereby improving the operational convenience and flexibility of the side where the fixed-end connection device 10 is located. It should be noted that when the graphitization furnace 31 is implemented as a movable graphitization furnace, the illustration of the ground 100 can also be understood as a ground support. Figure 1Also shown is the furnace bottom space 102 and the conductive busbar 103, which are related to the connection method of the movable end connection device 20 on the other side and will be further explained below. The fixed end connection device 10 has a simple structure and a stable and reliable connection. The conductive cross-section of the busbar (the area where the first conductive member 11 and the second conductive member 14 are located) can be large or small, regardless of manufacturing difficulty. When the pressure plate 12 is implemented as a hollow liquid-cooled pressure plate, no external cooling facilities are required.

[0042] refer to Figures 5 to 8 The mobile terminal connection device 20 is suitable for use with Figure 11 The second burner 312 is connected, and the mobile terminal connection device 20 also includes Figures 1 to 4 The electrode holder 101 shown in the figure also includes a conductive connection structure. Generally, due to the limitations of the graphitization production scene, if the power supply is set at a random position, it will lead to difficulties in wiring and operating the conductive connection between the two opposite furnace heads. Generally, the power supply can be implemented as a rectifier transformer, located at Figure 11 The exterior of the graphitization furnace 31 is shown. In this embodiment, one of the first furnace heads 311 is preferably set as a fixed end and the second furnace head 312 on the other side is set as a movable end. In actual operation, the first furnace head 311 is set closer to the power supply, and the conductive connection structure is used to connect the second furnace head 312, which is farther away from the power supply, with conductive transmission, thereby optimizing the wiring of the power transmission wires in the graphitization production scenario. In this embodiment, reference Figure 5 One end of the electrode holder 101 is used to clamp the furnace head electrode 300, and the other end is connected to the power supply through a conductive connection structure.

[0043] In the mobile terminal connection device 20, according to Figures 5 to 8 The conductive connection structure also includes a third conductive member 21 and a conductive busbar 103. The third conductive member 21 is arranged on a side of the second conductive member 14 away from the first conductive member 11 in a liftable manner. One end of the third conductive member 21 is suitable for connecting to the second conductive member 14, and the other end is suitable for connecting to the conductive busbar 103. The conductive busbar 103 is used to connect to the power supply. Specifically, in this embodiment, the third conductive member 21 extends along the first direction A (which can also be understood as Figure 1 The conductive connection structure further includes a second direction B perpendicular to the first direction A (which can also be understood as Figure 1The fourth conductive member 22 extends in the x-direction (as shown). The fourth conductive member 22 is suitable for being connected to multiple second conductive members 14 simultaneously. One end of the third conductive member 21 is suitable for being connected to multiple second conductive members 14 simultaneously through the fourth conductive member 22. It will be understood that the above configuration is made in this embodiment because there are multiple second conductive members 14. When a single second conductive member 14 is used, the fourth conductive member 22 can be omitted, and the third conductive member 21 can be directly connected to the second conductive member 14. The number of each conductive member in different embodiments of the present application can be set according to the actual production scenario.

[0044] More specific references Figure 6 In this embodiment, the conductive connection structure further includes a second telescopic device 23. When the third conductive member 21 is lowered, the top position of the third conductive member 21 is adapted to be opposite to the fourth conductive member 22. The second telescopic device 23 is adapted to push the top position of the third conductive member 21 to press the fourth conductive member 22 after activation. In one embodiment, the second telescopic device 23 includes a hydraulic device. As previously mentioned, Figure 1 As described above, the graphitization furnace 31 is located on the ground 100. Figure 5 Combined with Figure 8 A furnace bottom space 102 is formed below the ground 100, and a conductive busbar 103 is disposed in the furnace bottom space 102. In this embodiment, a second telescopic device 23 is disposed above the ground to electrically connect the third conductive member 21 and the fourth conductive member 22, thereby establishing a connection with the second conductive member 14, so as to energize the furnace head electrode 300 located at the second furnace head 312. Further references Figure 6 , the conductive connection structure also includes a third telescopic device 24, the third telescopic device 24 is located in the furnace bottom space 102, when the third conductive member 21 is lowered, the bottom position of the third conductive member 21 is suitable for being opposite to the conductive busbar 103, and the third telescopic device 24 is suitable for pushing the bottom position of the third conductive member 21 to press the conductive busbar 103 after startup. In one embodiment, the third telescopic device 24 includes a hydraulic device. In this embodiment, the mobile end connection device 20 also includes a movable first movable platform 25, and the electrode holder 101 and the conductive connection structure are fixedly connected to the first movable platform 25. Preferably, the first movable platform 25 is located on the ground 100 through the first insulating roller 250. By providing the first movable platform 25, the power-on method on the side of the second furnace head 312 can be made more flexible. For example, when the graphitization furnace 31 is a movable graphitization furnace, after the graphitization furnace 31 reaches the power supply station, the power supply connection of the graphitization furnace 31 can be completed by pushing the first movable platform 25 to the position of the second furnace head 312. Compared with the cumbersome wiring method of related technologies, the operation difficulty is significantly reduced and the production cost is saved.

[0045] In order to better understand the structure of the mobile terminal connection device 20, Figure 5 and Figure 6 The diagram shows a working position in which the third conductive member 21 is connected to the second conductive member 14 and the conductive busbar 103 in the furnace bottom space 102. Figure 8 The figure shows the working position of the mobile terminal connecting device 20 when it has not yet completed docking with the second furnace head 312. Figure 5 and Figure 8 The third conductive member 21 is controlled by the lifting drive mechanism 26 to achieve Figure 5 The working principle and process of the mobile terminal connection device 20 are briefly explained below. Assuming that the power supply is located on the side of the first furnace head 311 opposite to the second furnace head 312, a conductive busbar 103 is arranged in the furnace bottom space 102 below the ground 100, one end of the conductive busbar 103 is connected to the power supply, and the other end is in the lower area of the furnace bottom space 102 near the opening 104, which is referred to as Figure 8 It is located on the ground 100. The first movable platform 25 carries the other components of the mobile terminal connection device 20 and moves to an area near the second furnace head 312. It is then lifted by the lifting drive mechanism 26. When the first movable platform 25 moves to a position where the third conductive member 21 is directly opposite the opening 104, the lifting drive mechanism 26 continues to control the third conductive member 21 to move downward until it extends into the furnace bottom space 102. It is understood that the above description only provides one method for controlling the third conductive member 21, and the present application is not limited thereto. In other embodiments of the present application, other means may be used to control the lifting and lowering of the third conductive member 21, and this is not a limitation.

[0046] When the third conductive member 21 moves downward until it extends into the furnace bottom space 102, the second and third retractable devices 23 and 24 are activated, respectively pushing the top of the third conductive member 21 against the second conductive member 14 and the bottom of the third conductive member 21 against the conductive busbar 103 located in the furnace bottom space 102, thereby completing the electrical connection between the second furnace head 312 and the power supply. The conductive path on the second furnace head 312 consists of the furnace head electrode 300, the first conductive member 11, the second conductive member 14, the fourth conductive member 22, the third conductive member 21, the conductive busbar, and the power supply. Correspondingly, on the first furnace head 311, the conductive path consists of the furnace head electrode 300, the first conductive member 11, the second conductive member 14, and the power supply. These first and second furnace heads 311 and 312 can be connected to the positive and negative poles of the power supply, respectively, to form a conductive path.

[0047] More preferably, Figure 9 A modified embodiment of the mobile terminal connection device 20 is shown. Figure 9A schematic diagram of a second mobile terminal connection device 20' is shown. In the second mobile terminal connection device 20', other components identical to those of the mobile terminal connection device 20 described above are numbered the same. In this embodiment, a flexible section 210 is specifically provided between the top and bottom positions of the third conductive member 21. This flexible section 210, through a soft connection, allows for more flexible control of the movement of the third conductive member 21. As described above, the second telescopic device 23 is adapted to push the top position of the third conductive member 21 to compress the fourth conductive member 22 after activation, and the third telescopic device 24 is adapted to push the bottom position of the third conductive member 21 to compress the conductive busbar 103 after activation. In actual operation, the second telescopic device 23 and the third telescopic device 24 can typically be activated simultaneously. To prevent the top and bottom positions of the third conductive member 21 from being completely compressed simultaneously against the fourth conductive member 22 and the conductive busbar 103 due to factors such as device process errors, the flexible section 210 can be used to provide appropriate conditions to achieve a better compression effect during electrical connection.

[0048] on the other hand, Figure 10 A modified embodiment of the fixed end connection device 10 is shown. Figure 10 A schematic diagram of a second fixed-end connection device 10' is shown. Components identical to those in the fixed-end connection device 10 described above are numbered the same. In this embodiment, the fixed-end frame 16 in the fixed-end connection device 10 described above further comprises a fixed platform 161 and a second movable platform 162 positioned on the fixed platform 161. The fixed platform 161 is fixed to the ground 100, and the second movable platform 162 is supported on the fixed platform 161 by second insulating rollers 163. This embodiment preferably also includes a fourth telescopic device 17 connected to the second movable platform 162. Upon activation, the fourth telescopic device 17 is adapted to propel the second movable platform 162 to move relative to the furnace head electrode 300. The provision of the fourth telescopic device 17 allows the second movable platform 162 to slightly move left and right relative to the furnace head electrode 300, allowing for flexible position adjustment when the first furnace head 311 is docked with the second fixed-end connection device 10'. In one embodiment, the fourth telescopic device 17 comprises a hydraulic device.

[0049] Another aspect of this application refers to Figure 11 A graphitization production system 30 is proposed. The graphitization production system 30 includes a power supply (not shown), a graphitization furnace 31, and a quick connect / disconnect system according to any embodiment of the present application. The graphitization furnace 31 has a first furnace head 311 and a second furnace head 312 facing each other. The first furnace head 311 and the second furnace head 312 each include one or more furnace head electrodes 300. Figures 1 to 10Taking the illustrated embodiment as an example, the quick connect / disconnect system includes a fixed-end connection device 10 and a movable-end connection device 20. The fixed-end connection device 10 is adapted to be connected to the first furnace head 311 and includes an electrode holder 101. One end of the electrode holder 101 is used to hold the furnace head electrode 300, and the other end is used to connect to a power source supplying power to the graphitization furnace 31. On the other hand, the movable-end connection device 20 is adapted to be connected to the second furnace head 312 and includes an electrode holder 101 and a conductive connection structure. One end of the electrode holder 101 is used to hold the furnace head electrode 300, and the other end is connected to the power source via the conductive connection structure. Specifically, the electrode holder 101 includes a first conductive member 11 located on both sides of each furnace head electrode 300, a pressure plate 12, and a first telescopic device 13 connected to the pressure plate 12. Upon activation, the first telescopic device 13 is adapted to push the pressure plates 12 located on both sides of the furnace head electrode 300, thereby pushing the first conductive member 11 toward the furnace head electrode 300 and causing the first conductive member 11 to press against the furnace head electrode 300 from both sides. For other structural details, operating principles, and processes of the graphitization production system 30, please refer to the previous description and will not be repeated here.

[0050] Preferably, the graphitization furnace 31 is a movable graphitization furnace, which is located at Figure 1 On the ground 100 shown, there is a furnace bottom space 102 below the ground 100, wherein the fixed end connection device 10 of the quick connection and disconnection system is connected to the power supply through the electrode holder 101; the mobile end connection device 20 of the quick connection and disconnection system is connected to the power supply through a conductive connection structure, and the conductive connection structure is located in the furnace bottom space 102. When the graphitization furnace 31 is a movable graphitization furnace, the above-mentioned quick connection and disconnection system of the present application can achieve a more obvious improvement effect. Nevertheless, the present application is not limited to this. For traditional fixed graphitization furnaces, the above-mentioned quick connection and disconnection system of the present application can also achieve a good wiring improvement effect. At this time, the ground 100 is actually the ground position where the graphitization furnace 31 is located. The furnace bottom space 102 can be realized by digging a groove under the ground. The above method can optimize the flexibility, mobility and automation of the power supply mode of the graphitization furnace, which can solve the safety hazards caused by manual operation, thereby significantly saving costs and reducing the difficulty of engineering construction.

[0051] Further preferably, the graphitization production system 30 may include a power transmission station and multiple graphitization furnaces 31 implemented as movable graphitization furnaces. The multiple movable graphitization furnaces are suitable for sequentially reaching the power transmission station and then connecting to the power supply through the quick connection and disconnection system of any embodiment of the present application. Compared with some existing fixed graphitization furnace implementations, multiple fixed graphitization furnaces are operated to transmit power simultaneously, and each furnace requires an external conductive busbar to connect to the power supply; while the multiple movable graphitization furnaces in this embodiment are moved to the power transmission station in sequence. For the entire graphitization production system 30, only a small number of conductive busbars need to be arranged at a single power transmission station or a small number of power transmission stations. Taking the production implementation using one power transmission station as an example, the entire system only needs a conductive busbar slightly larger than the length of the movable graphitization furnace body to realize the sequential power transmission and production of multiple movable graphitization furnaces. Compared with the relevant existing technology, a large number of conductive busbars are saved, thereby significantly saving costs. Nevertheless, for the implementation method of the traditional fixed graphitization furnace, if the optimized quick connection and disconnection system proposed in this application is adopted, the improvement effect can be achieved, especially with the advantages of saving a lot of manpower for power connection and optimizing the wiring of the conductive busbar. Compared with the relevant existing technologies, it can also reduce costs.

[0052] It can be seen from the above explanation that although the quick connect and disconnect system of the present application can be applied to both fixed graphitization furnaces and movable graphitization furnaces and can achieve improved effects, the effect of applying it to the movable graphitization furnace is more significant compared with the two. In order to better understand the beneficial technical effects of the above-mentioned implementation method of the movable graphitization furnace using the technical solution of the present application, the relevant background technology and principles are further explained below. In industrial production, graphitization is regarded as a synonym for high energy consumption and high pollution due to its production characteristics. In addition to the product, a large amount of auxiliary materials, such as thermal insulation materials and conductive heating materials, need to be loaded into the graphitization furnace, and the auxiliary materials need to consume a lot of electricity. During the power supply process of the graphitization furnace, especially under high temperature conditions, harmful substances in the furnace loading materials are discharged, which are seriously polluting and difficult to collect and treat. In order to change the backward situation of the graphitization industry, the use of mobile graphitization is a better and feasible solution to the double high graphitization problem. The basic method of mobile graphitization is to move the graphitization furnace to the corresponding working area to carry out operations such as loading the furnace, supplying power, cooling, and unloading. Under the mobile graphitization mode, the flue gas can be fully collected and processed, and the carbon dust generated by loading and unloading the furnace can be effectively collected and utilized, changing the high-pollution image. This application particularly improves the power supply station. Mobile graphitization reduces the distance between the high-current conductive busbar and the overall energy consumption to achieve a low-energy consumption effect. In some embodiments, the pressure plate adjacent to the electrode is set as a hollow liquid-cooled pressure plate, which can further improve safety and eliminate the need for external cooling equipment. The movable graphitization furnace with the product installed is moved to the vicinity of the power supply, connected to the power supply through the high-current conductive busbar, and power is supplied to the furnace to a high temperature. In the actual production process, the large current of graphitization is basically above 200,000 amperes, so the connection and disconnection between the graphitization furnace head and the conductive busbar is a very complicated mechanism. For a mobile graphitization furnace, when the graphitization furnace is moved near a power source, the furnace is quickly and stably connected to the conductive busbar. After the power supply to the graphitization furnace is completed, the furnace and the conductive busbar are quickly disconnected without affecting the movement of the graphitization furnace. This is an important link in the promotion and application of mobile graphitization. Therefore, the optimized quick connection and disconnection system proposed in this application is a device for quickly connecting the mobile graphitization furnace to the high-current conductive busbar, realizing a fast, stable and reliable connection and disconnection device between the graphitization furnace and the high-current busbar without the need for external cooling, significantly improving the power supply problem in the graphitization production field.

[0053] Another aspect of this application refers to Figure 12A method 40 for supplying power to a graphitization furnace is proposed, applicable to the graphitization production system proposed in any embodiment of the present application. The method 40 includes the following steps: Step 41: connecting the first burner of a mobile graphitization furnace to the fixed-end connection device of a quick-connect / disconnect system; Step 42: connecting the second burner to the mobile-end connection device of the quick-connect / disconnect system; and Step 43: energizing a power source to establish electrical connections between the first and second burners, respectively. Using the method 40, power can quickly and stably connect and disconnect the burner electrodes of the graphitization furnace. It also optimizes the flexibility, portability, and automation of the graphitization furnace's power supply mode, mitigates safety hazards associated with manual operation, significantly saves costs, and reduces the difficulty of engineering construction.
