Description

Technical Field

[0001] This utility model relates to the technical field of negative electrode material sintering equipment, specifically a combined graphite sagger for negative electrode material sintering. Background Technology

[0002] The modular graphite sagger for sintering negative electrode materials is a key piece of equipment in the production of lithium-ion battery negative electrode materials. It is mainly used in the high-temperature sintering process. Its core function is to provide a uniform and stable sintering environment for the negative electrode material (graphite), ensuring the stability of the material structure and performance, and improving the sintering efficiency of graphite. In most cases, graphite negative electrode materials are sintered by placing the graphite inside the graphite sagger and then sintering it through the combustion chamber. However, existing graphite saggers are basically one-piece structures. After the sintering process is completed, the graphite material needs to be removed. However, this one-piece graphite sagger increases the difficulty of material removal. Moreover, if the one-piece graphite sagger is damaged by impact later, the entire piece needs to be replaced, which increases the economic burden on enterprises and has poor practicality.

[0003] To overcome the above-mentioned defects, in the prior art 1 (Chinese patent application number CN201921899290.2, application date 2019-11-06), a quality testing device for pharmaceutical packaging composite film uses a modular graphite crucible assembled by connecting and splicing with screws. Because of its modular structure, the structure of each component in the modular graphite crucible—including the base plate, side plates, vertical inner support column, and screws—is simpler, easier to manufacture, more efficient, and lower in cost. Furthermore, if a part of the graphite crucible is damaged, only the damaged part can be replaced. The components are readily replaceable, thus reducing the processing and manufacturing difficulty and cost of graphite saggers, and improving production efficiency and practicality. Although existing technologies can disassemble and replace graphite saggers, reducing the economic burden on enterprises, the high temperature generated during sintering can cause the screws and other limiting parts used in the assembly of existing graphite saggers to melt, resulting in poor assembly efficiency and inability to guarantee stability. Therefore, a modular graphite sagger for sintering negative electrode materials has been proposed to effectively solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a modular graphite sagger for sintering negative electrode materials, in order to solve the problem mentioned in the background art that, in actual use of existing graphite saggers on the market, the high temperature generated during sintering causes the limiting parts such as screws used in the assembly of existing graphite saggers to melt, resulting in poor assembly efficiency and inability to guarantee the stability of the graphite sagger.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined graphite sagger for sintering negative electrode materials, comprising a sagger body and side mounting plates disposed on both sides of the sagger body for sintering processing. Support legs are symmetrically installed below the sagger body. Limiting strips are installed at the bottom ends of the two side mounting plates, and the bottoms of the two limiting strips are connected to limiting grooves, which are symmetrically opened inside the sagger body.

[0006] Preferably, the limiting strip and the limiting groove form an engaging structure.

[0007] Preferably, the inner sides of the sagger body and the side mounting plate are respectively provided with a first sliding groove and a second sliding groove, and the first sliding groove and the second sliding groove are slidably connected to each other.

[0008] Preferably, the opposing surfaces of the first slider and the second slider are connected to a support column, and the support column is triangular in shape.

[0009] Preferably, the support columns are arranged in four positions, and the four support columns are respectively located at the four corners of the inner wall of the sagger body.

[0010] Preferably, the bottom of the sagger body is symmetrically provided with through holes, and a row of push rods are slidably installed inside the through holes, with the bottom ends of the push rods extending through to the lower outer side of the sagger body.

[0011] Preferably, an operating plate is connected to the bottom end of one row of top rods, and the lowest point of the operating plate is higher than the lowest point of the support leg.

[0012] 8. The combined graphite sagger for sintering negative electrode materials, characterized in that: the sagger body, side mounting plate, support leg, support column, first slider, second slider, top rod, operating plate and limiting strip are made of high-precision graphite material.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) Support columns are provided. Four support columns are installed on the inner wall of the sagger body, and two side mounting plates are connected to the outside of the support columns. The stability between the sagger body and the two side mounting plates can be increased by the four support columns, so as to avoid deformation and damage to the sagger body and the two side mounting plates due to high temperature or compression collision, and improve the stability of the sagger body and the two side mounting plates in use.

[0015] (2) A first slider and a second slider are provided. The first slider and the second slider are installed on both sides of the support column respectively. Then, the first slide groove and the second slide groove are slidably connected on the outside of the first slider and the second slider. When it is necessary to position and install the side mounting plate, the side mounting plate can be placed on both sides of the sagger body. Then, the support column is slidably connected to the first slide groove and the second slide groove through the first slider and the second slider respectively. The sagger body and the side mounting plate can be quickly assembled by the first slider and the second slider. The operation is more time-saving and labor-saving.

[0016] (3) Furthermore, by installing a limit strip at the bottom of the side mounting plate and then engaging a limit groove at the bottom of the limit strip, the position of the side mounting plate can be positioned and fixed after installation through the engagement of the limit groove and the limit strip, resulting in better stability.

[0017] (4) A top rod is provided. A row of top rods is symmetrically slidably installed through the through hole groove at the bottom of the sagger body. An operating plate is connected to the bottom of the row of top rods. When it is necessary to disassemble and replace the side mounting plate after installation, the top rods can be moved upward by the operating plate. The row of upward-moving top rods will press the side mounting plate upward by the limit strip, so that the side mounting plate can be disassembled and replaced. The operation is more time-saving and labor-saving.

[0018] (5) Furthermore, since the sagger body, side mounting plate, support leg, support column, first slider, second slider, top rod, operating plate and limit bar are all made of high-precision graphite material, there will be no melting damage when they are sintered with negative electrode material in the later stage, thus improving the sintering efficiency of the sagger body.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides the following technical solution: a combined graphite sagger for sintering negative electrode materials:

[0028] Example 1: To address the problem that in the actual use of existing graphite saggers, the high temperature generated during sintering causes the screws and other limiting parts used in assembling the sagger body 1 to melt, resulting in poor assembly efficiency and unreliable stability of the sagger body 1, the following is disclosed: a sagger body 1, and side mounting plates 2 set on both sides of the sagger body 1 for sintering processing. Support legs 3 are symmetrically installed on the bottom of the sagger body 1. Limiting strips 13 are installed at the bottom of the two side mounting plates 2, and the bottom of the two limiting strips 13 is connected to limiting grooves 12. The two limiting grooves 12 are symmetrically opened inside the sagger body 1.

[0029] The limiting strip 13 and the limiting groove 12 form a locking structure. The inner sides of the sagger body 1 and the side mounting plate 2 are respectively provided with a first sliding groove 7 and a second sliding groove 8. The first sliding groove 7 and the second sliding groove 8 are slidably connected to a first slider 5 and a second slider 6. The opposite sides of the first slider 5 and the second slider 6 are connected to a support column 4. The support column 4 is triangular in shape. There are four support columns 4. The four support columns 4 are respectively set at the four corners of the inner wall of the sagger body 1.

[0030] like Figures 1-4As shown, when the negative electrode material needs to be sintered, the negative electrode material is simply placed inside the sagger body 1. Then, the two side mounting plates 2 are installed on both sides of the sagger body 1 through the two limiting strips 13 and the locking grooves 12. Subsequently, the four support columns 4 are slidably installed inside the first sliding groove 7 and the second sliding groove 8 through the first slider 5 and the second slider 6. The first slider 5 and the second slider 6 can be used to facilitate quick assembly of the sagger body 1 and the side mounting plates 2, avoiding the phenomenon of loosening and falling off the two side mounting plates 2 during the later positioning and assembly. The stability is better because the sagger body 1, the side mounting plates 2, the support legs 3, the support columns 4, the first slider 5, the second slider 6, the top rod 9, the operating plate 10 and the limiting strips 13 are all made of high-precision graphite material. They can avoid melting and damage when sintering with the negative electrode material in the later stage, which improves the sintering efficiency of the sagger body 1 and makes it more practical.

[0031] Example 2 differs from Example 1 in that an auxiliary disassembly mechanism can be used to assist in the disassembly and replacement of the side mounting plate 2, making the operation more time-saving and labor-saving. The following is disclosed:

[0032] The bottom of the sagger body 1 is symmetrically provided with through holes 11, and a row of push rods 9 are slidably installed inside the through holes 11. The bottom end of the push rods 9 extends through to the lower outer side of the sagger body 1. The bottom end of the row of push rods 9 is connected to the operating plate 10, and the lowest point of the operating plate 10 is higher than the lowest point of the support leg 3. The sagger body 1, the side mounting plate 2, the support leg 3, the support column 4, the first slider 5, the second slider 6, the push rods 9, the operating plate 10, and the limiting strip 13 are made of high-precision graphite material.

[0033] like Figures 1-6 As shown, when it is necessary to disassemble and replace the two side mounting plates 2 after installation, simply use the operating plate 10 to drive a row of push rods 9 to move upwards, so that the row of push rods 9 can move upwards through the through hole slot 11. At this time, the row of push rods 9 will push the side mounting plates 2 connected by the limit strip 13 to move upwards, thereby realizing the auxiliary disassembly and replacement of the side mounting plates 2, which is more time-saving and labor-saving.
