Description

Technical Field

[0001] This disclosure generally relates to the field of materials processing technology. More specifically, this disclosure relates to a production system for graphitization. Background Technology

[0002] Currently, the production of graphitized materials typically involves heating crucibles containing raw materials using graphitization furnaces. To achieve large-scale production, a common approach is to increase the size of the graphitization furnace to boost capacity. However, as the furnace size increases, the performance requirements for the corresponding transport and loading / unloading mechanisms also rise. Existing graphitization production systems rarely have systems well-suited for large furnaces, and their automation levels are generally low. This often leads to complex feeding and discharging procedures and difficulties in transferring high-temperature crucibles. This increases both production safety risks and production costs.

[0003] In view of this, there is an urgent need to provide a production system for graphitization that is compact in structure and has high transportation and handling efficiency. Summary of the Invention

[0004] In order to at least address one or more of the technical problems mentioned above, this disclosure proposes a production system for graphitization.

[0005] This disclosure provides a production system for graphitization, comprising: a plurality of graphitization furnaces, each graphitization furnace having an elongated furnace body extending along a first direction, the plurality of graphitization furnaces being arranged side-by-side along their width; a first transport system including a track and a transport device corresponding to the track, the track including two segments at least partially opposite to the sides of the plurality of graphitization furnaces along the length direction of the graphitization furnaces; a second transport system including a second track and a second transport device moving along the second track, the second track extending along the length direction above the track, enabling the second transport device to transfer materials between the plurality of graphitization furnaces and the first transport system along the length direction; and a loading and unloading assembly including a receiving section for receiving graphitized materials from the first transport system, and an output section for conveying materials to be processed to the first transport system, the receiving section and the output section both being connected to segments of the track of the first transport system parallel to the length direction.

[0006] In some embodiments, the first transportation system includes a first track and a third track, both of which are formed in a loop, with the first track surrounding the third track.

[0007] In some embodiments, the first transport system includes a first segment, a second segment, and a third segment connected in sequence, wherein two adjacent segments are perpendicular to each other, and a loading and unloading assembly is disposed in the second segment.

[0008] In some embodiments, the loading and unloading assembly is disposed between the first track and the third track.

[0009] In some embodiments, the loading and unloading assembly is used to receive graphitized material from a transport device on a first track and to transfer the material to be processed to a transport device on a third track.

[0010] In some embodiments, a cooling zone is also included, which is positioned adjacent to the third track and below the second track, so that the second transport device can move materials along the length direction between the plurality of graphitization furnaces, the cooling zone and the first transport system.

[0011] In some embodiments, both the first track and the third track are formed in a ring shape, with the first track surrounding the third track, and the cooling zone is disposed inside the third track.

[0012] In some embodiments, an auxiliary material handling component is also included, which is at least partially positioned adjacent to the third track and below the second track, so that the second transport device can move materials along the length direction between the plurality of graphitization furnaces, the auxiliary material handling component and the first transport system.

[0013] In some embodiments, the second transport device further includes a first trolley assembly and a second trolley assembly, which are disposed on the same second track. The first trolley assembly includes a material conveying mechanism, and the second trolley assembly includes an auxiliary material receiving mechanism. The second trolley assembly is disposed close to the auxiliary material handling assembly.

[0014] In some embodiments, a material distribution line is also included, which includes a feeding mechanism for receiving raw materials, a raw material storage mechanism connected to the feeding mechanism and the loading and unloading assembly, and a finished product storage mechanism connected to the loading and unloading assembly for receiving processed materials. The material distribution line is located on the side of the first transport system away from the graphitization furnace along the width direction of the graphitization furnace.

[0015] The graphitization production system provided above, through the arrangement of multiple graphitization furnaces, a first transport system semi-enclosing the graphitization furnaces, loading and unloading components, and a second transport system for transporting materials between the graphitization furnaces, the first transport system, and the loading and unloading components, enables a more compact layout of the graphitization production system, improves the automation level of graphitization processing, and allows for more efficient processing and recycling of high-temperature materials.

[0029] The specific embodiments disclosed herein will now be described in detail with reference to the accompanying drawings.

[0030] For clarity and ease of understanding, in the following description, the length direction of the graphitization furnace in the production system is generally considered the first direction, and the width direction is considered the second direction. The side of the graphitization furnace along its width direction towards the side not surrounded by the first transport system is considered the rearward direction, and the opposite direction is considered the forward direction. The side facing the center of the graphitization furnace is considered the inner side, and the side facing away from the graphitization furnace is called the outer side. Unless otherwise specified, the positional descriptions of other related components will also be based on this. The purpose of the above description is only to provide a reference direction for describing the relative positional relationships of the various structures, and not to limit the actual structural arrangement of the embodiments in this disclosure.

[0031] This disclosure provides a production system for graphitization, which, by setting up multiple graphitization furnaces, a loading and unloading assembly for replacing and loading materials processed in the graphitization furnaces and materials to be processed, a first transport system semi-enclosed outside the graphitization furnaces to transfer materials between the graphitization furnaces and the loading and unloading assembly, and a second transport system for transferring materials between the graphitization furnaces and the first transport system, enables the production system to be more compact and to perform high-temperature material processing cycles in a more efficient manner.

[0032] Figure 1 An exemplary top view of a production system for graphitization according to some embodiments of this disclosure is shown. In some embodiments, the production system for graphitization may include a plurality of graphitization furnaces 10, a first transport system 20 partially surrounding the graphitization furnaces 10, a loading and unloading assembly 40 for loading and unloading materials, and a second transport system 30 for transporting materials between the graphitization furnaces 10 and the first transport system 20. The plurality of graphitization furnaces 10 may be, for example, heating furnaces such as electric furnaces or fuel furnaces capable of generating high temperatures (above 1000°C). The first transport system 20 may include, for example, a first track 21, which may be partially surrounding the plurality of graphitization furnaces 10. The loading and unloading assembly 40 may include, for example, a material loading and unloading mechanism for retrieving materials transported by the transport system and loading new materials to be processed into the first transport system 20. The second transport system 30 may include a second track 31, which may connect, for example, the graphitization furnaces 10 and the first transport system 20.

[0033] Specifically, in some embodiments, the graphitization furnace 10 may include a generally rectangular furnace body, which may be configured to have a relatively long length in a first direction. For example, its width may be less than 10 meters, while its length may be more than 40 meters to meet temperature and capacity requirements. At both ends of the graphitization furnace 10 along its length, for example, human-machine interfaces, switches, control systems, etc., may be provided for controlling or detecting the status of the graphitization furnace 10. The upper side of the graphitization furnace 10 may be configured to be openable to allow a transport device to load and unload materials. Multiple graphitization furnaces 10 may be arranged side by side along their width, so that their ends along their length are substantially aligned, facilitating access for operators to the corresponding switches, human-machine interfaces, control systems, etc. Simultaneously, the aligned ends of multiple graphitization furnaces 10 also facilitate unified power supply and transformer configurations, especially for large graphitization furnaces. Large-scale power distribution equipment can be used to uniformly distribute power to multiple graphitization furnaces 10 arranged compactly along a straight line. The power distribution lines are simple and easy to maintain, and the branch lines are shorter, which is conducive to realizing the large-scale of the equipment and improving the output of finished products per unit of energy.

[0034] In some embodiments, the material to be processed and the processed material can be loaded into containers for transport. The containers for holding the material can be made of heat-resistant materials, such as high-temperature resistant containers like graphite crucibles used in graphitization production. The containers, along with the material they contain, are heated together in the graphitization furnace 10 and transported by transport mechanisms such as the first transport device 23 and the second transport device 32. The containers may include, for example, a shell for containing the material and a lid for closing the shell.

[0035] In some embodiments, the first transport system 20 may include a first track 21 and a first transport device 23 disposed on the first track 21. The first track 21 may be, for example, a double track, and the first transport device 23 may be a rail transport vehicle corresponding to the double track. For example, multiple rail transport vehicles may be disposed sequentially on the first track 21 to improve transport efficiency. The second track 31 of the second transport system 30 may be disposed vertically on the upper side of the graphitization furnace 10 and the first track 21 to transfer materials from above to the first transport device 23 on the first track 21. In some embodiments, the second transport system 30 may be, for example, a material transfer crane, wherein the second track 31 is the crane track of the material transfer crane, and the second transport device 32 may be a material transfer crane that moves along the crane track, which may include, for example, material transfer actuators such as picking grippers or suction pipes, and is controlled by a drive mechanism such as a motor to move the material transfer actuators vertically to the target position for picking up or releasing materials.

[0036] See Figure 2 , Figure 2 An exemplary top view of a first transport system for a graphitization production system according to some embodiments of this disclosure is shown. The first transport system 20 may be configured to include three sections: a first section 25, a second section 26, and a third section 27, which are interconnected and at an angle to each other to form a first transport system 20 that semi-encloses the graphitization furnace 10. For example, the first transport system 20 may include a first track 21, which may be generally U-shaped, comprising three segments connected sequentially and perpendicular to each other. Two opposing segments of the U-shape may be arranged along a first direction along the length of the graphitization furnace 10 on both sides of the furnace 10, at least partially opposite to it, while the other segment extends along the first direction parallel to the length of the furnace 10. The two opposing segments of the U-shape may constitute the first section 25 and the third section 27, respectively, while the segment arranged along the first direction may constitute the second section 26.

[0037] In some embodiments, the first track 21 can be formed as a ring-shaped track structure. For example, the first track 21 is generally arranged in two forward-opening "U" shapes in the first section 25 and the third section 27, while the first track 21 in the third section 27 can include two segments extending parallel to each other along a first direction, the two segments respectively connecting the open ends of the front sides of the two "U"-shaped structures to close the first track 21. In this case, the first track 21 is generally formed as a "U" shape, and each of its sections includes two segments arranged parallel to each other and spaced apart. As a result, more first transport devices 23 can be provided in the first transport system 20, expanding its capacity for storing and transferring materials. Moreover, the isolation space between the multiple segments provides operating space for the maintenance of production and testing equipment, improving the production and maintenance performance of the equipment.

[0038] In some embodiments, the first transport system 20 may further include a third track 22 and a third transport device 24 disposed on the track. Similar to the first track 21, the first track 21 may be, for example, a double track, and the third transport device 24 may be one or more rail transport vehicles corresponding to the double track. The third track 22 may, for example, have a similar shape to the first track 21 and be disposed adjacent to the first track 21. The first transport device 23 and the third transport device 24 on the mutually separated first track 21 and third track 22 may be configured to transport materials in two different directions, or to receive materials before or after processing, respectively. Thus, for example, the scheduling of the transport devices on the two tracks can be managed separately to improve transport efficiency, or the structure or transport actions of the first transport device 23 and the third transport device 24 on the two tracks can be adjusted according to different transport conditions to further optimize transport efficiency and effectiveness.

[0039] When the first track 21 is formed as a ring, the third track 22 can also be formed as a similar ring. In some embodiments, the first track 21 and the third track 22, which are formed as rings, can be nested within each other. For example, the third track 22 can have a smaller size so that it can be surrounded by the first track 21. Thus, more third transport devices 24 can be provided on the third track 22, thereby further increasing the transport capacity of the first transport system 20.

[0040] See Figure 3 , Figure 3 It shows Figure 1An enlarged schematic diagram of part A. In some embodiments, a receiving space for accommodating the loading and unloading assembly 40 may be provided between the first track 21 and the third track 22. For example, when the first track 21 and the second track 31 are arranged in a nested ring, the first track 21 and the third track 22 together comprise four parallel segments in the second section 26 of the first transport system 20. The two middle segments are the segments of the third track 22 nested within the first track 21 in the second section 26, while the two outer segments are the segments of the first track 21 in the second section 26. Among these four segments, the two segments closer to the graphitization furnace 10 may be arranged adjacent to each other, while the two segments farther from the graphitization furnace 10 may be arranged at intervals. Thus, the space between the two segments arranged at intervals encloses a receiving space 210 that can be used to accommodate the loading and unloading assembly 40. The loading and unloading assembly 40 may be integrally disposed within the receiving space 210 formed by the first track 21 and the third track 22 in the second section 26. The loading and unloading assembly 40 can be close to the first track 21 and the third track 22 in both directions, thereby reducing the transfer distance required when feeding or picking up materials to the first track 21 and the third track 22, thus saving the time required for material transportation and improving production efficiency.

[0041] The material handling mechanism of the loading and unloading assembly 40 may include, for example, a picking assembly 421 and a loading assembly 422. The picking assembly 421 may include, for example, a suction device to suck material out of the container. The loading assembly 422 may include, for example, a feeding bin with a valve at the outlet, which can fill the container with material by setting the outlet above the container opening and opening the gate. The loading and unloading assembly 40 may also include a first transfer device 41 for transferring material between the first transport system 20 and the material handling mechanism. The first transfer device 41 may include, for example, a conveying mechanism for connecting two or more of the first track 21, the third track 22, the picking assembly 421, and the loading assembly 422, and may include a horizontal conveyor belt or conveyor rollers.

[0042] The material loading and unloading mechanism may include a receiving section 43 for receiving materials from the first transport system 20, and an output section 44 for transferring new materials to be processed to the first transport system 20. In some embodiments, the receiving section 43 may be located on the side of the material loading and unloading mechanism near the graphitization furnace 10, and the section of the third track 22 near the graphitization furnace 10 in the second section 26 may be connected to the receiving section 43 to transfer materials to the material loading and unloading mechanism. The output section 44 may be located on the side of the material loading and unloading mechanism away from the graphitization furnace 10, so that the section of the first track 21 away from the graphitization furnace 10 in the second section 26 may be connected to the output section 44. Thus, the two annular first tracks 21 and third tracks 22 can complete the automatic cycle of receiving and transferring materials from the first transport system to the loading and unloading assembly 40, and then receiving and transferring materials from the loading and unloading assembly 40 back to the first transport system, thereby improving the automation level of material transfer, increasing efficiency, and reducing safety hazards caused by personnel approaching the furnace-discharged materials. Meanwhile, by arranging the multiple conveying mechanisms of the first transfer device 41 in a segmented manner parallel to the first track 21 and the third track 22 along the first direction, the loading and unloading assembly 40 can be arranged side by side with the tracks on both sides. Since the loading and unloading assembly 40 requires a relatively long equipment length for buffering and transporting the corresponding materials, arranging it side by side with the tracks on both sides also significantly saves equipment space.

[0043] Furthermore, although the above describes a scheme for arranging the material loading and unloading mechanism in the accommodating space between the first track 21 and the third track 22, this disclosure does not limit the specific positional relationship between the material loading and unloading mechanism and the first transport system 20. For example, see... Figure 5 , Figure 5 An exemplary top view of a graphitization production system according to some embodiments of this disclosure is shown. In some embodiments, the first transport system may include, for example, only a single annular first track 21, and a material loading and unloading mechanism may be disposed within the annular structure of the first track 21, and the material loading and unloading mechanism may also be located in the region of the first track 21 corresponding to the second segment 26 of the first transport system. The receiving part 43 of the material loading and unloading mechanism may be connected to the segment of the first track 21 in the second segment 26 near the graphitization furnace 10, while its output part 33 may be connected to the segment of the first track 21 away from the graphitization furnace 10. Thus, the first transport system can have a more compact layout, and the scheduling of the transport devices is also simpler.

[0044] See Figure 6 , Figure 6An exemplary top view of a graphitization production system according to some embodiments of this disclosure is shown. In some other embodiments, the receiving unit 43 and the output unit 44 may also be located on the same side of the material loading and unloading mechanism. For example, when the first transport system 20 includes only one first track 21, the material loading and unloading mechanism may be located within the annular structure of the first track 21, and the material loading and unloading mechanism may also be located in the area of ​​the first track 21 corresponding to the second section 26 of the first transport system. The receiving unit 43 and the output unit 44 are simultaneously connected to the side of the first track 21 in the second section 26 near the graphitization furnace 10 to receive material from the track or transfer material back to the track, thereby allowing for a more compact equipment layout. In addition, multiple material loading and unloading mechanisms may be provided, or a single material loading and unloading mechanism may be configured to have multiple receiving units 43 and output units 44, to further improve efficiency.

[0045] In some embodiments, a cooling zone 60 for cooling the material exiting the furnace may be provided near the first section 25 or the second section 26. The cooling zone 60 may be, for example, a flat surface for placing high-temperature materials, a cooling pit below the horizontal plane, or other active or passive cooling devices. The second track 31 of the second transport system 30 may be at least partially provided above the cooling zone 60, such that after the second transport device 32 of the second transport system 30 removes the material from the graphitization furnace 10, it can transport the material or a container containing the material along the second track 31 to the cooling zone 60 for cooling.

[0046] When the first track 21 and / or the third track 22 are formed as a ring, the cooling zone 60 can be disposed, for example, inside the first track 21 and / or the third track 22. For example, the bending radius of the track at the curved portion can be increased at the first segment 25 and / or the third segment 27 of the first track 21 and / or the third track 22, and the distance between the two parallel segments of the inner side of the first track 21 and / or the third track 22 at the first segment 25 and / or the third segment 27 can be increased. Thus, the first track 21 and / or the third track 22 can enclose the cooling zone 60. In some other embodiments, two cooling zones 60 located at the first segment 25 and the third segment 27 respectively can be provided to further increase the storage capacity.

[0047] Because the cooling zone 60 is located inside the first track 21 and / or the third track 22, and materials can only be loaded and unloaded through the second transport system 30, the first track 21, the third track 22, and the first transport device 23 and the third transport device 24 mounted on the tracks form a barrier separating personnel from the high-temperature graphitization container to be cooled, reducing the risk of personnel directly contacting the high-temperature graphitization crucible. Furthermore, the cooling zone 60 is located in the first section 25 and / or the third section 27 of the first transport system 20, and is relatively close to the graphitization furnace 10, reducing the time high-temperature materials remain in the transport device and minimizing damage to the transport device from high temperatures. Simultaneously, material buffering can be completed with a short transport distance, improving the flexibility of the production system in responding to different production conditions. For example, when multiple batches of materials need to be removed from the graphitization furnace 10 in a short time, but the number of transport devices is insufficient or malfunctions, the second transport system 30 can be used to quickly temporarily store the materials in the graphitization furnace 10 in the cooling zone 60, preventing material accumulation due to excessive travel distance.

[0048] See Figure 4 , Figure 4 It shows Figure 1 The diagram shows an enlarged view of part B. When using a graphitization furnace 10 for graphitization production, heating auxiliary materials are often filled into the furnace for auxiliary heating. The amount of these auxiliary materials used is large, and they need to be replaced frequently. Therefore, in some embodiments, an auxiliary material processing component 50 may be included for recycling the auxiliary materials in the graphitization furnace 10. The auxiliary material processing component 50 may include, for example, a screening device 51 and a first conveying device 52 and a second conveying device 53 connected to the screening device 51. The screening device 51 can be used to screen materials such as heating auxiliary materials from the graphitization furnace. The first conveying device 52 may be used to receive raw materials transferred from the second transport system 30 and transfer them to the screening device 51. The second conveying device 53 can be used to transport the screened material back to the corresponding area of ​​the second transport system 30 so that the second transport system 30 can receive the screened material.

[0049] In some embodiments, the first conveying device 52 of the auxiliary material processing assembly 50 includes a receiving section 521, and the second conveying device 53 includes a feeding section 531. At least a portion of the auxiliary material processing assembly 50 may be disposed within the third section 27 of the first transport system 20, and may be positioned adjacent to the third track 22 and below the second track 31. Similar to the cooling zone 60, the bending radius of the first track 21 and / or the third track 22 at the curved portion can be increased at the third section 27 of the third track 22, and the distance between the two parallel segments of the inner side of the third track 22 at the third section 27 can be increased. Thus, the third track 22 can enclose the auxiliary material processing area for the auxiliary material processing assembly 50, allowing the second transport system 30 to transport heated auxiliary materials between the auxiliary material processing assembly 50, the first transport system 20, and the graphitization furnace 10. The first conveying device 52 and the second conveying device 53 can be arranged side-by-side with the segments of the first track 21 and the third track 22 in the third section 27, that is, the transport direction of the heated auxiliary material is the same as the arrangement direction of the first track 21 and the third track 22 in the third section 27. Thus, the first track 21, the third track 22, and the first transport device 23 and the third transport device 24 arranged on the tracks form a barrier separating personnel from the auxiliary material handling assembly 50 used to handle the heated auxiliary material, reducing the risk of personnel directly contacting the high-temperature auxiliary material.

[0050] In some embodiments, the second transport device 32 of the second transport system 30 may further include multiple transport mechanisms. For example, the second transport device 32 may include a first trolley assembly 321 and a second trolley assembly 322, which are disposed on the second track 31 and operate independently of each other. The first trolley assembly 321 may include, for example, a material conveying mechanism, which may include grippers capable of vertical lifting and lowering. The grippers can be used to grip containers containing materials to transfer materials between the graphitization furnace 10, the third track 22, or the cooling zone 60. The second trolley assembly 322 may include, for example, an auxiliary material receiving mechanism, which may include a negative pressure generating device and an auxiliary material storage bin. It can generate negative pressure by means of the negative pressure generating device to draw auxiliary materials into the auxiliary material storage bin. Further, it can move along the second track 31 to above the receiving section 521 and open the gate on the auxiliary material storage bin to output auxiliary materials.

[0051] In some embodiments, the production system may include a plurality of parallel second tracks 31, each of which may be provided with a corresponding second transport device 32. For example, in some embodiments, two second tracks 31 may be provided parallel along a second direction, wherein each second track 31 is provided with a first trolley assembly 321 and a second trolley assembly 322. The first trolley assembly 321 may be configured to move along a first direction toward a first section 25 of the first transport system 20, while the second trolley assembly 322 may be configured to move along a first direction toward a third section 27. Thus, the first trolley assembly 321 can be used to transfer materials between the graphitization furnace 10, the cooling zone 60, and the third transport device 24, while the second trolley assembly 322 can transfer heated auxiliary materials between the graphitization furnace 10 and the first conveying device 52 and the second conveying device 53 of the auxiliary material processing assembly 50.

[0052] Furthermore, when multiple graphitization furnaces 10 are arranged side-by-side along the second direction and their length direction is parallel to the first direction, the length direction of the multiple graphitization furnaces 10 is the same as the movement direction of the first trolley assembly 321 on the second track 31. Simultaneously, by utilizing the first section 25 and the third section 27 of the first transport system 20 respectively located on both sides of the graphitization furnace 10 along the first direction, bidirectional material discharge along the length direction of the graphitization furnace 10 can be achieved. Moreover, after the material in one graphitization furnace 10 has completed graphitization processing, the second transport system 30 handles the processed material within the upper area of ​​the opened graphitization furnace 10, reducing the risk of accidentally interfering with the production processing of other graphitization furnaces 10 due to the lateral movement of high-temperature materials across them.

[0053] Since the first transport assembly 321 and the second transport assembly 322 can share a single track, and the first transport assembly 321, used for transporting graphitized materials, and the second transport assembly 322, used for transporting heating auxiliary materials, are used in different production stages, they essentially do not interfere with each other. This allows the first transport assembly 321 to move back and forth between the first section 25 and the third section 27 of the first transport system 20, and thus, based on the location of the material it acquires, it can select the side with the shortest travel distance to transport the material. This further improves material transfer efficiency and reduces the residence time of high-temperature materials in the transport device. At the same time, the overall structure of the production system is more compact, which in turn reduces the travel distance required for the first transport device 23 and the second transport device 32, improving production efficiency and reducing production costs. Furthermore, because the overall layout of the production system is more compact and centralized, the treatment of flue gas from the production system is also easier, further reducing the health risks to on-site production personnel.

[0054] In some embodiments, the production system further includes a material distribution line 70, which may be used, for example, to feed raw materials to be processed into the loading assembly 422 in the loading and unloading assembly 40 for loading, and to retrieve processed materials from the loading and unloading assembly 40. The material distribution line 70 may include, for example, a feeding mechanism 71 and a raw material storage mechanism 72. The feeding mechanism 71 may include, for example, a hopper for receiving materials and a dispersing device for initially dispersing the materials into powder or granular form. After passing through the feeding mechanism 71, the materials can be conveyed to the raw material storage mechanism 72 via pipelines using methods such as negative pressure conveying. The raw material storage mechanism 72 can be connected to the loading assembly 422 in the loading and unloading assembly 40 via pipelines to transfer the materials to be processed to the loading assembly 422 for loading.

[0055] In some embodiments, the material distribution line 70 further includes a finished product storage mechanism 73 for storing processed materials. The finished product storage mechanism 73 can be connected to the material handling component 421 in the loading and unloading component 40 via a pipeline, so that the processed materials obtained by the material handling component 421 can be transported to the finished product storage mechanism 73 by means of negative pressure, etc., and further transported to the packaging mechanism for packaging. The production system may also include a dust removal device 80, which may include, for example, a vacuum generating component for providing a vacuum and a dust removal mechanism for filtering and removing dust. It can be connected to the respective components of the production system via pipeline, for example, to collect flue gas by negative pressure and to filter dust particles in the flue gas by the dust removal mechanism, so as to further reduce the adverse effects of flue gas generated during the production process on personnel health. The feeding mechanism 71, the raw material storage mechanism 72, the finished product storage mechanism 73, the dust removal device 80, and the screening component can be arranged sequentially along the first direction and disposed on the side of the second section 26 of the first transport system 20 away from the graphitization furnace 10. Therefore, the connection between equipment such as the raw material storage mechanism 72 and the finished product storage mechanism 73 and mechanisms such as the loading and unloading assembly 40 can be shortened to save energy required for transportation.

[0056] The graphitization production system disclosed herein, through the arrangement of multiple graphitization furnaces, loading and unloading components, a first transport system semi-enclosed with the graphitization furnaces for transferring materials between the graphitization furnaces and the loading and unloading components, and a second transport system for transporting materials between the graphitization furnaces and the first transport system, enables a more compact layout of the graphitization production system, improves the automation level of graphitization processing, performs high-temperature material processing cycles in a more efficient manner, and reduces the health hazards to personnel caused by high temperatures and fumes during the production process.
