Description

Technical Field

[0001] This utility model belongs to the field of graphite sagger technology, specifically a spliced ​​graphite sagger. Background Technology

[0002] Graphite saggers are widely used carrier containers in high-temperature heat treatment and sintering processes, primarily for the high-temperature sintering of electrode materials such as lithium iron phosphate, ternary cathode materials, graphene, and battery anode materials. In these processes, the sagger holds the materials and is placed in a high-temperature furnace. Its structural form has gradually evolved from the traditional integral molding type to a modular structure to improve material utilization and maintainability.

[0003] Chinese patent application CN208366086U discloses a variable-size, modular sagger, comprising a sagger base and sagger walls. The sagger base is assembled from bottom corners, bottom walls, a bottom center block, and a universal bottom block. The sagger walls are assembled from curved side walls and straight side walls. In the ceramic production process, for the production of art porcelain or new products, this invention solves the need for saggers of different sizes. It is reusable and can be assembled into different sizes, effectively reducing the cost of ordering and producing a large number of saggers of different models and increasing firing efficiency.

[0004] Although the structure can adapt to the sintering requirements of saggers of different sizes, the sagger structure is a single chamber and cannot be divided into chambers of the same volume to sinter different types of electrode materials in one go. It is not suitable for small-batch, diversified production needs. Utility Model Content

[0025] However, there may be instances where unnecessary detailed descriptions are omitted. For example, detailed descriptions of well-known matters or repetitive descriptions of essentially the same structures may be omitted. This is to avoid unnecessarily lengthy descriptions and to facilitate understanding by those skilled in the art. Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this application and are not intended to limit the subject matter of the claims.

[0026] Please see Figure 1-4 As shown in the embodiment of this utility model, a spliced ​​graphite sagger includes a sagger base plate 1, an installation frame plate 2 is provided on the sagger base plate 1, positioning installation plates 3 are provided around the upper part of the installation frame plate 2, and a partition sagger plate 4 is snapped onto the four positioning installation plates 3.

[0027] The upper part of the four positioning mounting plates 3 is provided with a snap-fit ​​structure for detachable connection with the partition box plate 4. The partition box plate 4 is made of graphite material and can be inserted and snapped between the positioning mounting plates 3. The partition box plate 4 is used to divide the internal space of the entire graphite sagger into multiple independent areas. In this embodiment, it is preferable to divide the internal space evenly into four sub-areas to facilitate the simultaneous sintering of four different workpieces.

[0028] In use, first place the sagger base plate 1 on the workbench, confirm that the structure of the mounting frame plate 2 and its surrounding positioning mounting plates 3 are intact, and then install the partition sagger plates 4 in sequence at the snap-fit ​​parts between the positioning mounting plates 3 to form several independent chambers. Each chamber contains the electrode material to be sintered. After assembly, the overall structure is stable and well-sealed. The electrode material to be sintered is placed in the four independent areas formed by the partition. The sagger can be divided into chambers of the same volume, and different types of electrode materials can be sintered in one go. It is suitable for small-batch and diversified production needs.

[0029] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the sagger base plate 1 and the mounting frame plate 2 adopt an integral molding design, which can improve the strength and rigidity of the overall structure. The integral molding structure can reduce the thermal interface, improve the thermal conductivity consistency of the sagger as a whole, help the furnace temperature to be evenly distributed, and improve the heating consistency and quality stability of each workpiece inside the graphite sagger.

[0030] In one embodiment, see Figure 1 and Figure 4 As shown, a support plate 5 is also provided around the upper part of the mounting frame plate 2. The support plate 5 has several through holes 51, and the mounting frame plate 2 has several mounting holes 21. The mounting frame plate 2 and the support plate 5 are installed together by fasteners such as graphite screws through the through holes 51 and the mounting holes 21, forming a stable connection structure. This improves the overall assembly efficiency and consistency of the crucible. The multi-point fastening can also effectively avoid uneven installation stress caused by local thermal deformation, improve the strength and load-bearing capacity of the overall structure, and prevent the structure from loosening or shifting due to thermal expansion, mechanical impact or external force deformation.

[0031] Specifically, please refer to Figure 1 , Figure 2 and Figure 3As shown, each of the four positioning mounting plates 3 is provided with a positioning groove 31, and a partition box plate 4 is snapped into each of the four positioning grooves 31. The positioning grooves 31 provide stable positioning for the partition box plate 4, preventing it from being misaligned or falling off during high-temperature use, ensuring the sealing and reliability of the overall structure. The partition box plate 4 is installed in the positioning groove 31 by snapping, which is a boltless structure, making disassembly and assembly more convenient. It also reduces the risk of damage to metal fasteners due to thermal expansion and contraction in high-temperature environments and improves the reusability of the box assembly.

[0032] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 As shown, mounting base plates 6 are also provided around the upper perimeter of the sagger base plate 1. Each of the four mounting base plates 6 is provided with a limiting groove 61, and a partition sagger plate 4 is engaged within the four limiting grooves 61. The mounting base plates 6 with raised edges are formed on the sagger base plate 1, and the mounting base plates 6 and the sagger base plate 1 can be integrally sintered. Each mounting base plate 6 is provided with a limiting groove 61, and the partition sagger plate 4 is provided with insertion sections around its perimeter. After the four insertion sections are inserted into the limiting grooves 61, the partition sagger plate 4 is stably supported on the mounting base plate 6.

[0033] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 As shown, the partition box plate 4 includes a supporting main board 41, on which several partition plates 42 are detachably connected. The partition plates 42 can be detachably connected to the positioning groove 31 and the limiting groove 61 on both the upper and lower sides. The partition box plate 4 is composed of the supporting main board 41 and multiple partition plates 42 connected by graphite screw threads. The partition box plate 4 is precisely positioned at both ends by inserting its upper and lower ends into the positioning groove 31 and the limiting groove 61 of the mounting base plate 6, ensuring that the structure does not shift or warp during the high-temperature sintering process.

[0034] Further, please refer to Figure 1 , Figure 2 and Figure 3 As shown, a transition arc portion 43 is provided between each of the two adjacent partition plates 42. The connection between the partition plate 42 and other structures is a high-temperature area for hot working. The design of the transition arc portion 43 can effectively reduce stress concentration and improve the thermal shock resistance and crack resistance of the connection structure.

[0035] Further, please refer to Figure 1 , Figure 2 and Figure 3As shown, each partition plate 42 is provided with a mounting part 44, which is snapped between the positioning groove 31 and the limiting groove 61. Each partition plate 42 has a mounting part 44 at both ends, which is a boss-shaped structure. Its size is precisely matched with the groove width of the positioning groove 31 and the limiting groove 61. During installation, the operator aligns the upper and lower ends of the partition plate 42 with the positioning groove 31 on the mounting frame plate 2 and the limiting groove 61 on the mounting base plate 6, respectively. The mounting part 44 is firmly snapped into the groove by inserting it downwards. After installation, a stable vertical or horizontal partition bracket is formed, which is used to divide the internal area into multiple independent heating reaction spaces.

[0036] Further, please refer to Figure 1 , Figure 2 and Figure 3 As shown, several heat-conducting ribs 45 are provided on the partition plate 42. The heat-conducting ribs 45 are integrally formed with the partition plate 42. As a reinforcing rib of the plate, the heat-conducting ribs 45 can improve the overall bending resistance of the partition plate 42 under high temperature environment and avoid problems such as warping and deformation due to prolonged heating. The heat-conducting ribs 45 can form a more orderly heat flow path inside the graphite sagger, which helps the heat in the furnace to circulate more evenly in the sagger, and improves the controllability of the heating process and the consistency of the product.

[0037] Please see Figure 1 , Figure 2 and Figure 3 As shown, a protective plate 7 is also provided around the bottom plate 1 of the sagger. The protective plate 7 is located around the bottom plate 1 of the sagger and below the mounting frame plate 2. Its height is lower than that of the side plate. As an outer edge protection structure, the protective plate 7 can effectively prevent the edge of the bottom plate 1 of the sagger from being bumped or impacted during handling, loading and unloading or assembly, thus extending the service life of the equipment. The protective plate 7 forms a ring-shaped enclosure structure at the bottom, which can play a certain role in structural reinforcement and support, making the entire sagger structure more stable and less prone to deformation.

[0038] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
