Description

Technical Field

[0001] This application relates to the field of graphite crucible technology, specifically a combined box-type graphite crucible. Background Technology

[0002] The production of graphite anode materials mainly uses Atchison and internal series graphitization furnaces, in which the graphite anode materials are loaded into graphite crucibles for graphitization treatment.

[0003] An existing patent (publication number: CN218627725U) discloses a square, modular graphite crucible, comprising a base plate, four side plates, and four mounting shafts. Circular through holes are formed on the upper surface of the base plate and inside the four side plates. A transmission cylinder is movably sleeved on the outer surface of each mounting shaft, and a pressure plate is fixedly connected to the lower surface of each transmission cylinder. A spiral transmission groove is formed on the top of the outer surface of each mounting shaft. This square, modular graphite crucible, by directly inserting the mounting shaft into the circular through holes to limit the movement of the side plates and base plate, only requires adjusting the limiting rod to fit the rectangular groove and then rotating the transmission cylinder to cause the transmission cylinder to drive the pressure plate downwards relative to the mounting shaft. This allows the pressure plate to easily and stably compress the upper surface of the side plates, making the connection between the four side plates and the base plate convenient. The crucible can be assembled without tools, greatly improving its ease of use.

[0004] The aforementioned device limits the side plates and bottom plate by directly inserting the mounting shaft into the circular through hole. Simply move the limiting rod to match the rectangular groove, and then rotate the transmission cylinder to make the transmission cylinder drive the pressure plate to move downward relative to the mounting shaft. This allows the pressure plate to press the upper surface of the side plates relatively conveniently and stably. However, due to the circular through hole, the sealing at the connection between two side plates is low, which can easily lead to leakage. Furthermore, the above-mentioned crucible is not convenient to flexibly adjust the capacity according to actual needs during use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a combined box-type graphite crucible, which has advantages such as flexible adjustment and solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a combined box-type graphite crucible, including a base plate, a limiting ring provided on the outer side of the base plate, a rectangular limiting groove provided on the bottom wall of the base plate, and four limiting threaded holes arranged in a circle on the upper surface of the base plate;

[0007] Multiple stacked components are located on top of the chassis;

[0008] Each of the stacked components includes a rectangular ring, a rectangular sealing ring is fixedly connected to the bottom of each rectangular ring, a rectangular sealing groove is formed on the upper surface of each rectangular ring, and a through threaded hole is formed on the upper surface of each rectangular ring.

[0009] The above scheme, through the arrangement of stacked components, achieves modular combination of graphite crucibles. Users can freely stack different numbers of stacked components according to actual needs, thereby adjusting the overall height and capacity of the graphite crucible. This not only improves the flexibility of the graphite crucible but also enables it to better adapt to graphitization processing tasks of different scales and types. The combined use of rectangular sealing grooves and rectangular sealing rings significantly improves the overall sealing performance of the graphite crucible. Compared with the traditional circular through-hole connection method, the rectangular sealing structure more effectively prevents the risk of leakage of graphite negative electrode material during the graphitization process, thereby ensuring product quality and production efficiency. The combined use of double-ended screws and connecting threaded holes achieves the purpose of pressing multiple stacked components, further improving the sealing performance and stability of the graphite crucible.

[0010] Furthermore, two sets of connecting rods are inserted into both sides of the chassis, and a handle is fixedly connected to the top of each set of connecting rods.

[0011] The above solution, with its handle design, makes it easy for users to move the entire unit.

[0012] Furthermore, each set of connecting rods is made of a material with low thermal conductivity, specifically ceramic.

[0013] The above solution and setup effectively reduce heat transfer to the outside through the connecting rod, thereby improving overall thermal efficiency and safety.

[0014] Furthermore, the outer surface of each handle is knurled.

[0015] The above solution and settings can increase the friction when the user holds the device, preventing accidental slippage or drop due to hand slippage.

[0016] Furthermore, each of the limiting threaded holes is internally threaded with a double-ended screw, each double-ended screw is inserted into a connecting threaded hole adjacent to it, and a throttle is fixedly connected to the top of each double-ended screw.

[0017] The above solution, through the setting of the throttle, can achieve the purpose of pressing multiple stacked components together, thereby improving the sealing performance.

[0018] Furthermore, a screw box is fixedly connected between the two connecting rods on the left side.

[0019] The above solution, through the design of the screw box, allows users to neatly place double-ended screws of different lengths, making them convenient to access and manage.

[0020] Furthermore, a throttle box is fixedly connected between the two connecting rods on the right side.

[0021] The above solution, through the setting of the throttle box, allows users to properly store the throttle when not in use, avoiding loss or damage.

[0022] Furthermore, both the top of the throttle box and the screw box are hinged with cover plates.

[0023] The above solution, through the setting of the cover plate, can achieve the purpose of sealing, effectively preventing the double-headed screw and the throttle from falling off during movement or storage, and ensuring the integrity of the overall structure and the safety of use.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] This modular box-type graphite crucible achieves modular assembly through the stacking components. Users can freely stack different numbers of components according to actual needs, thereby adjusting the overall height and capacity of the graphite crucible. This not only improves the flexibility of the graphite crucible but also makes it better adaptable to graphitization processing tasks of different scales and types. The combined use of rectangular sealing grooves and rectangular sealing rings significantly improves the overall sealing performance of the graphite crucible. Compared with the traditional circular through-hole connection method, the rectangular sealing structure more effectively prevents the risk of leakage of graphite negative electrode material during graphitization processing, thus ensuring product quality and production efficiency. The combined use of double-ended screws and connecting threaded holes achieves the purpose of pressing multiple stacked components, further improving the sealing performance and stability of the graphite crucible.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Please see Figure 1 and Figure 2 In this embodiment, a combined box-type graphite crucible includes a base plate 1. A limiting ring 2 is provided on the outer side of the base plate 1. A rectangular limiting groove 3 is provided on the bottom wall of the base plate 1. Four limiting threaded holes 4 arranged in a circle are provided on the upper surface of the base plate 1.

[0035] Multiple stacked components 5 are mounted on top of the chassis 1;

[0036] Please see Figure 1 , Figure 3 and Figure 4 Each stacking assembly 5 includes a rectangular ring 501, and a rectangular sealing ring 502 is fixedly connected to the bottom of each rectangular ring 501. A rectangular sealing groove 503 is opened on the upper surface of each rectangular ring 501, and a through threaded hole 504 is opened on the upper surface of each rectangular ring 501. By setting up the stacking assembly 5, users can stack the overall height according to actual needs, thereby adjusting the overall capacity. By setting up the rectangular sealing groove 503 and the rectangular sealing ring 502, the overall sealing performance can be improved.

[0037] Please see Figure 1 , Figure 2 and Figure 5 Two sets of connecting rods 6 are inserted into both sides of the chassis 1. Each set of connecting rods 6 has a handle 7 fixedly connected to its top. The handle 7 makes it easy for the user to move the whole unit. Each set of connecting rods 6 is made of a material with low thermal conductivity, specifically ceramic. This design effectively reduces the heat transfer to the outside through the connecting rods 6, improving the overall thermal efficiency and safety. The outer surface of each handle 7 is knurled. This design increases the friction when the user holds the handle, preventing accidental slippage or drop.

[0038] Please see Figure 1 , Figure 2 and Figure 5 Each limiting threaded hole 4 is internally threaded with a double-ended screw 8, and each double-ended screw 8 is inserted into its adjacent connecting threaded hole 504. The top of each double-ended screw 8 is threaded with a handle 12. The handle 12 is used to press multiple stacked components 5 together, improving sealing. A screw box 9 is fixedly connected between the two connecting rods 6 on the left side. The screw box 9 allows users to neatly place double-ended screws 8 of different lengths for easy access and management. A handle box 10 is fixedly connected between the two connecting rods 6 on the right side. The handle box 10 allows users to properly store the handle 12 when not in use, preventing loss or damage. The tops of the handle box 10 and the screw box 9 are hinged with a cover plate 11. The cover plate 11 provides a seal, effectively preventing the double-ended screws 8 and handle 12 from falling during movement or storage, ensuring the integrity of the overall structure and safety of use.

[0039] In this embodiment, a modular box-type graphite crucible is achieved through the stacking components 5, allowing users to freely stack different numbers of stacking components 5 according to actual needs, thereby adjusting the overall height and capacity of the graphite crucible. This not only improves the flexibility of the graphite crucible but also enables it to better adapt to graphitization processing tasks of different scales and types. The combined use of the rectangular sealing groove 503 and the rectangular sealing ring 502 significantly improves the overall sealing performance of the graphite crucible. Compared with the traditional circular through-hole connection method, the rectangular sealing structure more effectively prevents the risk of leakage of graphite negative electrode material during the graphitization process, thereby ensuring product quality and production efficiency. The combined use of the double-ended screw 8 and the connecting threaded hole 504 achieves the purpose of pressing multiple stacking components 5, further improving the sealing performance and stability of the graphite crucible.

[0040] The working principle of the above embodiment is as follows: First, the base plate 1, as the foundation of the graphite crucible, ensures the stability and accuracy of the stacking assembly 5 during the stacking process through the limiting ring 2 on its outer side and the rectangular limiting groove 3 on its bottom wall. The four circumferentially arranged limiting threaded holes 4 on the upper surface of the base plate 1 provide the basis for the subsequent clamping operation. Next, according to actual needs, the user can select an appropriate number of stacking assemblies 5 for stacking. The bottom of the rectangular ring 501 of each stacking assembly 5 is fixed with a rectangular sealing ring 502. When stacking, the rectangular sealing ring 502 will be embedded into the rectangular sealing groove 503 of the lower rectangular ring 501 to form a tight sealing structure, effectively preventing the graphite negative electrode material from seeping out during the graphitization process. After stacking is completed, the user needs to use the double-ended screw 8 and the connecting threaded hole 504 for clamping operation. Each limiting threaded hole 4 is screwed with a threaded hole 8. The connection includes a double-ended screw 8, the other end of which is inserted into the threaded hole 504 of the adjacent stacked assembly 5. By rotating the handle 12 at the top of the double-ended screw 8, multiple stacked assemblies 5 can be pressed together, further improving the sealing and stability of the graphite crucible. In addition, to facilitate the storage and management of the double-ended screw 8 and the handle 12, connecting rods 6 are provided on both sides of the chassis 1. Screw boxes 9 and handle boxes 10 are fixed on the connecting rods 6 respectively. Screw boxes 9 are used to neatly place double-ended screws 8 of different lengths, while handle boxes 10 are used to properly store handles 12 when not in use to avoid loss or damage. Finally, to ensure the integrity of the overall structure and the safety of use, the top of handle boxes 10 and screw boxes 9 are hinged with cover plates 11 to achieve the purpose of closure and effectively prevent the double-ended screws 8 and handles 12 from falling off during movement or storage.
