Description

Technical Field

[0001] The present disclosure relates generally to the field of materials processing technology. More specifically, the present disclosure relates to a production system for graphitization. Background Art

[0002] Currently, the production of graphitized materials generally uses a graphitization furnace to heat the crucible containing the raw materials. Due to the needs of large-scale production, it is common to increase production capacity by increasing the equipment specifications of the graphitization furnace. However, as the size of the graphitization furnace increases, the performance requirements for the matching transportation and loading and unloading mechanisms are also increasing. However, existing graphitization production systems rarely have supporting production systems that can well adapt to large-scale graphitization furnaces, and the degree of automation is generally low. The complex operation procedures for feeding and discharging materials into the graphitization furnace and the difficulty of transferring high-temperature crucibles are often encountered. This not only increases production safety risks, but also increases production costs.

[0003] In view of this, there is an urgent need to provide a production system for graphitization so that the structure of the graphitization production system is compact and the transportation and processing efficiency is high. Utility Model Content

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

[0005] The present disclosure provides a production system for graphitization, comprising: a plurality of graphitization furnaces, each having a long furnace body extending along a first direction; a first transport system, comprising a track and a transport device arranged corresponding to the track, the track comprising two sections along the length direction of the graphitization furnaces, each section at least partially opposite to two sides of the plurality of graphitization furnaces; a second transport system, comprising a second track and a second transport device moving along the second track, the second transport device being capable of transferring materials between the plurality of graphitization furnaces and the first transport system along the length direction of the graphitization furnaces; and a loading and unloading assembly, comprising a receiving portion for receiving graphitized materials from the first transport system, and an output portion for delivering materials to be processed to the first transport system, the receiving portion and the output portion being both connected to the sections of the track of the first transport system parallel to the length direction.

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

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

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

[0012] In some embodiments, an auxiliary material handling assembly is further included, which is at least partially disposed adjacent to the third track and below the second track, so that the second transport device can transfer materials between the multiple graphitization furnaces, the auxiliary material handling assembly, and the first transport system along the length direction.

[0013] In some embodiments, the second transport device also includes a first car assembly and a second car assembly. The first car assembly and the second car assembly are arranged on the same second track. The first car assembly includes a material handling mechanism, the second car assembly includes an auxiliary material receiving mechanism, and the second car assembly is arranged close to the auxiliary material processing assembly.

[0014] In some embodiments, a material configuration line is further 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 configuration line is arranged on a side of the first transportation system away from the graphitization furnace along the width direction of the graphitization furnace.

[0015] Through the production system for graphitization provided above, the embodiment of the present disclosure provides multiple graphitization furnaces, a first transportation system semi-enclosed by the graphitization furnaces, a loading and unloading assembly, and a second transportation system for transporting materials between the graphitization furnaces, the first transportation system, and the loading and unloading assembly.

[0029] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0030] For clarity and ease of understanding, in the following description of this article, the length direction of the graphitization furnace in the production system is generally regarded as the first direction, and the width direction of the graphitization furnace is regarded as the second direction. At the same time, the direction from the graphitization furnace along its width toward the side not surrounded by the first transportation system is regarded as the rear direction, and the opposite direction is regarded as the forward direction. The side toward the center of the graphitization furnace is regarded as the inner side, and the side away from the graphitization furnace is referred to as the outer side. Unless otherwise specified, the position description of other related components will also be based on this. The purpose of adopting the above description is only to provide a reference direction for describing the relative positional relationship of each structure, and it does not limit the actual arrangement of the structures of each embodiment of the present disclosure.

[0031] The disclosed embodiments provide a production system for graphitization, which comprises a plurality of graphitization furnaces, a loading and unloading assembly for replacing and loading materials processed by the graphitization furnaces and materials to be processed, a first transportation system semi-enclosed outside the graphitization furnaces for transferring materials between the graphitization furnaces and the loading and unloading assembly, and a second transportation system for transferring materials between the graphitization furnaces and the first transportation system. The production system structure can be made more compact and the processing cycle of high-temperature materials can be performed in a more efficient manner.

[0032] Figure 1 An exemplary top view of a production system for graphitization according to some embodiments of the present disclosure is shown. In some embodiments, the production system for graphitization may include a plurality of graphitization furnaces 10, a first transport system 20 semi-enclosed outside the graphitization furnace 10, a loading and unloading assembly 40 for loading and unloading materials, and a second transport system 30 for transporting materials between the graphitization furnace 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, for example, include a first track 21, which may be semi-enclosed outside the plurality of graphitization furnaces 10. The loading and unloading assembly 40 may, for example, include a material loading and unloading mechanism to obtain the material it transports from the transport system and load new material to be processed into the first transport system 20. The second transport system 30 may include a second track 31, which may, for example, connect the graphitization furnace 10 and the first transport system 20.

[0033] Specifically, in some embodiments, the graphitization furnace 10 may include a long furnace body that is roughly rectangular in shape. The long furnace body may be configured to have a longer length in a first direction. For example, its width may be less than 10 meters, while its length may be greater than 40 meters to meet temperature conditions and capacity requirements. At both ends of the graphitization furnace 10 in the longitudinal direction, for example, a human-machine interface, switches, control systems, etc. for controlling the graphitization furnace 10 or detecting its status may be provided. 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 groups of graphitization furnaces 10 may be arranged side by side along their width so that their ends along the longitudinal direction are substantially aligned, making it easier for operators and inspectors to access corresponding switches, human-machine interfaces, control systems, etc. Furthermore, the aligned ends of multiple graphitization furnaces 10 also facilitate unified power supply and voltage transformation settings, especially for large graphitization furnaces. Large-scale power distribution equipment can be used to uniformly distribute power to multiple graphitizing furnaces 10 compactly arranged 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 large-scale equipment and improving the output of finished products per unit energy.

[0034] In some embodiments, the material to be processed and the processed material can be loaded into a container for loading and transport. The container for holding the material can be made of a heat-resistant material, such as a high-temperature resistant container such as a graphite crucible used in graphitization production. The container and the material filled therein are heated in the graphitization furnace 10 and transported by a transport mechanism such as the first transport device 23 and the second transport device 32. The container can include, for example, a shell for containing the material and a cover for sealing the shell.

[0035] In some embodiments, the first transport system 20 can be configured to include a first track 21 and a first transport device 23 disposed on the first track 21. The first track 21 can be, for example, a double-track track, and the first transport device 23 can be a rail transport vehicle corresponding to the double-track track. For example, a plurality of rail transport vehicles connected in sequence can be provided on the first track 21 to improve transport efficiency. The second track 31 of the second transport system 30 can be provided vertically on the upper side of the graphitization furnace 10 and the first track 21 to approach the graphitization furnace 10 and the first transport device 23 on the first track 21 from the upper side to transfer materials. In some embodiments, the second transport system 30 can 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 can be a material transfer crane that moves along the crane track, which can, for example, include material transfer actuators such as material retrieving claws or material suction pipes, and is controlled by a drive mechanism such as a motor to move the material transfer actuator vertically to the target position for retrieving or discharging materials.

[0036] See also Figure 2 , Figure 2 An exemplary top view of a first transport system of a graphitization production system according to some embodiments of the present disclosure is shown. The first transport system 20 can be configured to include three sections: a first section 25, a second section 26, and a third section 27. The three sections are interconnected and angled relative to each other to form the first transport system 20 that semi-encloses the graphitization furnace 10. For example, the first transport system 20 can include a first track 21. The first track 21 can be generally formed in a "U" shape, i.e., it includes three sections that are sequentially connected and perpendicular to each other. Two opposing sections of the U-shaped structure can be arranged along a first direction, respectively, on either side of the graphitization furnace 10 along the length of the graphitization furnace 10, and at least partially opposite to the graphitization furnace 10, while the other section extends along the first direction, parallel to the length of the graphitization furnace 10. The two opposing sections of the U-shaped structure can constitute the first section 25 and the third section 27, respectively, while the section arranged along the first direction can constitute the second section 26.

[0037] In some embodiments, the first track 21 can be formed into a track structure having a ring shape. For example, the first track 21 is roughly arranged as two "U" shapes with openings facing forward in the first section 25 and the third section 27, and the first track 21 can include two segments extending parallel to each other along the first direction in the third section 27, and the two segments are respectively connected to the open ends of the front sides of the above-mentioned two "U"-shaped structures to close the first track 21. At this time, the first track 21 is roughly formed into a "U" shape as a whole, 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. And the isolation space between the multiple segments provides operating space for the maintenance of production and inspection equipment, thereby 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 track, and the third transport device 24 may be one or more rail transport vehicles corresponding to the double-track track. The third track 22 may, for example, have a shape similar 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 first track 21 and the third track 22, which are disposed separately from each other, 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 may be managed separately to improve transport efficiency, or the structure or transport action of the first transport device 23 and the third transport device 24 on the two tracks may be adjusted according to different transport conditions to further optimize transport efficiency and effect.

[0039] When the first track 21 is formed into a ring, the third track 22 can also be formed into a similar ring. In some embodiments, the first track 21 and the third track 22 formed into rings can be arranged to be nested with each other. For example, the third track 22 can have smaller dimensions so that it can be surrounded by the first track 21. This allows more third transportation devices 24 to be installed on the third track 22, further increasing the transportation capacity of the first transportation system 20.

[0040] See also Figure 3 , Figure 3 Shown Figure 1An enlarged schematic diagram of section A in the figure. In some embodiments, a space for accommodating the loading and unloading assembly 40 can 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 comprise a total of four parallel segments in the second section 26 of the first transport system 20. The two middle segments are segments of the third track 22 nested within the first track 21 at the second section 26, while the two outer segments are segments of the first track 21 at the second section 26. Of these four segments, the two segments closer to the graphitization furnace 10 can be positioned adjacent to each other, while the two segments farther from the graphitization furnace 10 can be spaced apart. Thus, the spaced-apart segments enclose a space 210 for accommodating the loading and unloading assembly 40. The loading and unloading assembly 40 can be entirely disposed within the space 210 formed between 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 two directions, thereby reducing the transfer distance required for feeding or taking materials to the first track 21 and the third track 22, thereby saving the working hours required for material transportation and improving production efficiency.

[0041] The material loading and unloading mechanism of the loading and unloading assembly 40 may, for example, include a retrieving assembly 421 and a loading assembly 422, wherein the retrieving assembly 421 may, for example, include a suction device that uses the suction device to suck out the material contained in the container. The loading assembly 422 may, for example, include a feeding hopper with a valve at the discharge port. The discharge port can be positioned above the container opening and the valve is opened to release the material into the container. The loading and unloading assembly 40 may also include a first transfer device 41 for transferring material between the first transportation system 20 and the material loading and unloading mechanism. The first transfer device 41 may, for example, include a conveying mechanism for connecting two or more of the first track 21, the third track 22, the retrieving assembly 421, and the loading assembly 422, and may include a conveying mechanism such as a horizontal conveyor belt or conveyor rollers.

[0042] The material loading and unloading mechanism may include a receiving portion 43 for receiving material from the first transport system 20 and an output portion 44 for transferring new material to be processed to the first transport system 20. In some embodiments, the receiving portion 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 at the second section 26 may be connected to the receiving portion 43 to transfer material to the material loading and unloading mechanism. The output portion 44 may be located on the side of the material loading and unloading mechanism facing away from the graphitization furnace 10, so that the section of the first track 21 at the second section 26 away from the graphitization furnace 10 may be connected to the output portion 44. Thus, the two annular first track 21 and third track 22 can complete an automatic cycle of receiving and transferring material from the first transport system to the loading and unloading assembly 40, and then from the loading and unloading assembly 40 to the first transport system. This improves the automation of material transfer, while increasing efficiency and reducing safety hazards caused by personnel coming into close proximity with material leaving the furnace. At the same time, by arranging the multiple conveying mechanisms of the first transfer device 41 in parallel with the first track 21 and the third track 22 in this section along the first direction, the entire 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 long equipment length to cache and transport the corresponding materials, arranging it side by side with the tracks on both sides also significantly saves equipment space.

[0043] In addition, although the above shows a solution in which the material handling mechanism is arranged in the accommodation space between the first track 21 and the third track 22, the present disclosure does not limit the specific positional relationship between the material handling 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 the present disclosure is shown. In some embodiments, the first transport system may include, for example, only a single annular first track 21, and the material loading and unloading mechanism may be disposed within the annular structure of the first track 21. The material loading and unloading mechanism is also located in the area of ​​the first track 21 corresponding to the second section 26 of the first transport system. The receiving portion 43 of the material loading and unloading mechanism may be connected to the section of the first track 21 in the second section 26 that is close to the graphitization furnace 10, while the output portion 33 of the material loading and unloading mechanism may be connected to the section of the first track 21 that is away from the graphitization furnace 10. As a result, the first transport system can have a more compact layout, and the scheduling of the transport device is also simplified.

[0044] See also Figure 6 , Figure 6An exemplary top view of a production system for graphitization according to some embodiments of the present disclosure is shown. In some other embodiments, the receiving portion 43 and the output portion 44 may also be arranged 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 arranged within the annular structure of the first track 21, and the material loading and unloading mechanism is also located in the area of ​​the first track 21 corresponding to the second section 26 of the first transport system. The receiving portion 43 and the output portion 44 are simultaneously connected to the side of the first track 21 in the second section 26 close to the graphitization furnace 10 to receive materials from the track or transfer materials back to the track, thereby making the equipment layout more compact. In addition, multiple material loading and unloading mechanisms may be provided, or one material loading and unloading mechanism may be provided with multiple receiving portions 43 and output portions 44 to further improve efficiency.

[0045] In some embodiments, a cooling zone 60 for cooling the discharged material 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 material, a cooling pit below the horizontal surface, or other active or passive cooling devices. The second track 31 of the second transport system 30 may, for example, be at least partially provided above the cooling zone 60, so that after the second transport device 32 of the second transport system 30 removes the material from the graphitization furnace 10, it may transfer the material or the 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 in a ring shape, the cooling zone 60 can be provided within the first track 21 and / or the third track 22. For example, the curvature radius of the first section 25 and / or the third section 27 of the first track 21 and / or the third track 22 can be increased, thereby increasing the distance between the two parallel sections of the first track 21 and / or the third track 22 at the first section 25 and / or the third section 27. This allows the first track 21 and / or the third track 22 to enclose the cooling zone 60. In other embodiments, two cooling zones 60, one located in the first section 25 and the other in the third section 27, can be provided to further increase storage capacity.

[0047] Because the cooling zone 60 is located inside the first track 21 and / or the third track 22, and materials therein can only be accessed and placed via the second transport system 30, the first track 21, the third track 22, and the first and third transport devices 23, 24 disposed thereon 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 within the first section 25 and / or the third section 27 of the first transport system 20, which is relatively close to the graphitization furnace 10. This reduces the time that high-temperature materials remain in the transport device and minimizes damage to the transport device caused by high temperatures. Furthermore, material buffering can be completed with a minimal number of transport trips, improving the flexibility of the production system in responding to diverse production conditions. For example, if multiple batches of materials need to be removed from the graphitization furnace 10 in a short period of time, but the number of transport devices is insufficient or malfunctions, the second transport system 30 can be used to quickly and temporarily store the materials in the graphitization furnace 10 in the cooling zone 60, eliminating the accumulation of materials due to excessively long travel times.

[0048] See also Figure 4 , Figure 4 Shown Figure 1 An enlarged schematic diagram of part B in FIG. When the graphitization furnace 10 is used for graphitization production, heating auxiliary materials are often filled into the graphitization furnace 10 for auxiliary heating. The amount of heating auxiliary materials used is large and needs to be replaced frequently. In this regard, in some embodiments, an auxiliary material processing assembly 50 for circulating the auxiliary materials in the graphitization furnace 10 may also be included. The auxiliary material processing assembly 50 may, for example, include 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 for the graphitization furnace. The first conveying device 52 can, for example, be used to receive raw materials transferred by 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 materials back to the corresponding area of ​​the second transport system 30 so that the second transport system 30 can receive the screened materials.

[0049] In some embodiments, the first conveyor 52 of the auxiliary material processing assembly 50 includes a material receiving portion 521, and the second conveyor 53 includes a material feeding portion 531. At least a portion of the auxiliary material processing assembly 50 can be disposed within the third section 27 of the first transport system 20, which can be disposed 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 can be increased at the third section 27 of the third track 22, and the distance between the two parallel sections of the inner side of the third track 22 at the third section 27 can be increased. In this way, the third track 22 can enclose the auxiliary material processing area for disposing the auxiliary material processing assembly 50, allowing the second transport system 30 to transport the heated auxiliary material between the auxiliary material processing assembly 50, the first transport system 20, and the graphitization furnace 10. The first conveyor 52 and the second conveyor 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 direction of transport of the heating auxiliary material is the same as the direction in which the first track 21 and the third track 22 are arranged in the third section 27. Thus, the first track 21, the third track 22, and the first conveyor 23 and the third conveyor 24 arranged on the tracks form a barrier that isolates personnel from the auxiliary material processing assembly 50 used to process the heating 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 car assembly 321 and a second car assembly 322, which are disposed on the second track 31 and operate independently of each other. The first car assembly 321 may, for example, include a material handling mechanism, which may include a clamp capable of vertical lifting and lowering. The clamp may be used to clamp a container containing material to transfer the material between the graphitization furnace 10, the third track 22, or the cooling zone 60. The second car assembly 322 may, for example, include an auxiliary material receiving mechanism, which may include a negative pressure generating device and an auxiliary material storage bin. The auxiliary material receiving mechanism may generate negative pressure using the negative pressure generating device to draw the auxiliary material into the auxiliary material storage bin. Furthermore, the auxiliary material receiving mechanism may move along the second track 31 to above the material receiving portion 521 and open the gate on the auxiliary material storage bin to discharge the auxiliary material.

[0051] In some embodiments, the production system may include a plurality of second rails 31 arranged in parallel, each of which may be provided with a corresponding second transport device 32. For example, in some embodiments, two second rails 31 may be provided, arranged in parallel along the second direction, wherein each second rail 31 may be provided with a first car assembly 321 and a second car assembly 322. The first car assembly 321 may be positioned along the first direction near the first section 25 of the first transport system 20, while the second car assembly 322 may be positioned along the first direction near the third section 27. Thus, the first car assembly 321 may be used to transfer materials between the graphitization furnace 10, the cooling zone 60, and the third transport device 24, while the second car assembly 322 may be used to transfer the heated auxiliary material between the graphitization furnace 10 and the first conveyor device 52 and the second conveyor 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, with their lengths parallel to the first direction, the lengths of the multiple graphitization furnaces 10 are aligned with the direction of movement of the first car assembly 321 on the second track 31. Simultaneously, by means of the first section 25 and the third section 27 of the first transport system 20, respectively disposed on either side of the graphitization furnace 10 along the first direction, bidirectional material discharge along the length of the graphitization furnace 10 can be achieved. Furthermore, after the material in one graphitization furnace 10 has completed graphitization, the second transport system 30 transports the processed material within the upper area of ​​the open graphitization furnace 10, reducing the risk of accidentally interfering with the production and processing of other graphitization furnaces 10 by clamping high-temperature material and moving it across and over them.

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

[0054] In some embodiments, the production system further includes a material configuration line 70, which can 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 configuration line 70 can, for example, include a feeding mechanism 71 and a raw material storage mechanism 72. The feeding mechanism 71 can, for example, include a hopper for receiving materials and a dispersing device for preliminarily dispersing the materials into powder particles. After passing through the feeding mechanism 71, the material can be transported to the raw material storage mechanism 72 through a pipeline by means of negative pressure conveying or the like, and the raw material storage mechanism 72 can be connected to the loading assembly 422 in the loading and unloading assembly 40 through a pipeline to transfer the material to be processed to the loading assembly 422 for loading.

[0055] In some embodiments, the material dispensing 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 retrieving assembly 421 in the loading and unloading assembly 40 via a pipeline, so that the processed materials obtained by the material retrieving assembly 421 can be transported to the finished product storage mechanism 73 by means of negative pressure, and further transported to the packaging mechanism for packaging. The production system can also include a dust removal device 80. The dust removal device 80 can, for example, include a vacuum generating assembly for providing vacuum and a dust removal mechanism for filtering and removing dust. The dust removal device 80 can, for example, be connected to various corresponding components of the production system via pipelines, collect flue gas through negative pressure, and filter dust particles in the flue gas through the dust removal mechanism to further reduce the adverse effects of the flue gas generated during the production process on human 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 assembly can be arranged in sequence along the first direction and disposed on the side of the second section 26 of the first transportation system 20 facing away from the graphitization furnace 10. As a result, 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 of some embodiments of the present disclosure is configured with multiple graphitization furnaces, loading and unloading assemblies, a first transportation system semi-enclosed with the graphitization furnace for transferring materials between the graphitization furnace and the loading and unloading assemblies, and a second transportation system for transporting materials between the graphitization furnace and the first transportation system. This enables the layout of the graphitization production system to be more compact, improves the degree of automation of the graphitization process, performs the processing cycle of high-temperature materials in a more efficient manner, and reduces the health hazards to personnel caused by high temperature and flue gas during the production process.
