Description

Technical Field

[0001] This utility model relates to the field of battery material sintering technology, specifically to a sintering sagger. Background Technology

[0002] Sintering saggers are round bowls of various sizes made of refractory clay, which are fired at high temperatures. They are mainly used to support the physicochemical reactions of raw materials at high temperatures, ensuring the purity, density, and structural uniformity of the product, and are commonly used in the sintering of materials.

[0003] Currently, ceramic saggers are commonly used in the production of battery materials. In order to increase production capacity, multi-layer sagger stacking is used in the actual production process. This not only causes poor exhaust in the lower layer of saggers, affecting product indicators and material quality, but also causes adjacent saggers in the same layer to stick together. This makes it inconvenient to use mechanical sagger disassembly after sintering, requiring manual intervention, increasing labor intensity, and reducing production efficiency. Utility Model Content

[0004] In view of this, the present invention provides a sintering sagger to solve the problem that in the existing sagger firing process, the air circulation in the lower layer of saggers is poor and adjacent saggers in the same layer are prone to sticking together.

[0005] In a first aspect, this utility model provides a sintering sagger, comprising:

[0006] The box body includes several side plates, and the top of each side plate is provided with a groove. Between adjacent boxes in the vertical direction, the groove of the lower box body and the bottom of the upper box body form a first flow channel.

[0007] A protrusion is provided on the outer side of the side plate, and the protrusions of adjacent boxes in the horizontal direction abut each other, forming a second flow channel between adjacent side plates.

[0008] Beneficial effects: When performing multi-layer sintering operations using stacked saggars, at least two saggars are stacked vertically. Due to the grooves at the top of the side walls, a first flow channel is formed between the groove of the lower saggar and the bottom of the upper saggar. This allows gas generated during sintering in the lower saggar to escape promptly, preventing it from affecting the material in the lower saggar. Simultaneously, the grooves reduce the contact area between the upper and lower saggars, reducing the possibility of adhesion. In the horizontal direction, multiple saggars are arranged sequentially, with the protrusions of adjacent saggars abutting each other, preventing the side walls of adjacent saggars from abutting each other. This effectively reduces the contact area between the side plates of adjacent saggars and creates a second flow channel between adjacent saggars in the horizontal direction. This allows air to fully enter between the saggars, preventing excessively high temperatures due to insufficient airflow between adjacent saggars, thus effectively reducing the possibility of adhesion between adjacent side plates. Even if adhesion occurs at the protrusions of the saggars, the small contact area reduces the difficulty of separation, thereby reducing labor intensity and improving production efficiency. The sintering sagger can form a first flow channel and a second flow channel when stacked, which can ensure that the gas generated by the battery material in the sintering is discharged smoothly, while reducing the possibility of adhesion between adjacent saggers.

[0009] In one alternative embodiment, the bottom corners on both sides of the groove are rounded.

[0010] Beneficial effects: The rounded bottom corners can strengthen the structural strength of the groove, eliminate stress concentration, avoid damage to the lower sagger when the saggers are stacked, and ensure the production yield of battery materials.

[0011] In one optional embodiment, the side plate is provided with a plurality of grooves, and the plurality of grooves are spaced apart.

[0012] Beneficial effects: While maintaining airflow, it can increase the support capacity of the side panels, ensuring structural stability and preventing damage when stacking the boxes.

[0013] In one alternative embodiment, the side plate further includes a support portion formed on both sides of the groove, the support portion abutting against the bottom of the upper casing.

[0014] Beneficial effects: The top of the side plate is recessed downward to form a groove, and then a support part is formed on both sides of the groove. The support part supports the upper box body. The structure is simple and easy to manufacture.

[0015] In one alternative embodiment, a limiting portion is provided at the bottom of the casing, the limiting portion being adapted to engage with the support portion.

[0016] Beneficial effects: By engaging the limiting part and the supporting part, the connection of the boxes stacked in the vertical direction can be made more stable, preventing the box on top from moving or shaking.

[0017] In one alternative embodiment, the protrusion includes a first portion that is in the shape of a line and extends horizontally along its length.

[0018] Beneficial effects: The two first parts opposite each other between adjacent housings are suitable for abutting together to form a second flow channel. The length direction of the first part extends in the horizontal direction, which can reduce the difficulty of aligning the two housings. Even if the two adjacent housings are misaligned in the horizontal direction, the first flow channel can be formed by at least part of the abutting of the two first parts, ensuring the flow of air.

[0019] In one alternative embodiment, the protrusion further includes a second portion, which is in the shape of a line and is perpendicular to the first portion.

[0020] Beneficial effects: When the two first parts of adjacent housings abut, the two second parts can also abut. The second parts are set perpendicular to the first parts, which ensures that even if the two adjacent housings are misaligned in the vertical direction, at least part of the two second parts can still abut to form a second flow channel, further ensuring the flow of air.

[0021] In one alternative implementation, the protrusion is cross-shaped.

[0022] Beneficial effects: The cross-shaped protrusions can reduce the impact of misalignment of the casing in both vertical and horizontal directions, ensuring the formation of a second flow channel and ensuring airflow. In addition, the cross-shaped protrusions occupy a small area, reducing the possibility of protrusion adhesion.

[0023] In one alternative implementation, the protrusion is circular.

[0024] Beneficial effects: The circular protrusions can also reduce the impact of misalignment of the sintering sagger in both the vertical and horizontal directions, ensuring the formation of a second flow channel and ensuring air flow. At the same time, the circular protrusions are easy to process, reducing the manufacturing difficulty of the sintering sagger.

[0025] In one optional embodiment, a plurality of protrusions are provided, and the plurality of protrusions are spaced apart along the length direction of the side plate.

[0026] Beneficial effects: The spacing of several protrusions along the length of the side plate makes the connection between each box more stable, allows the second flow channel to circulate air stably, and further reduces the possibility of adhesion. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] The following is combined Figures 1 to 3 The following describes embodiments of the present invention.

[0038] According to an embodiment of the present invention, a sintering sagger is provided, comprising: a sagger body 1 and protrusions 2. The sagger body 1 includes a plurality of side plates 11, the top end of the side plates 11 being provided with grooves 111, and between adjacent sagger bodies 1 in the vertical direction, the grooves 111 of the lower sagger body 1 and the bottom of the upper sagger body 1 form a first flow channel 3; the protrusions 2 are provided on the outer side surface of the side plates 11, and the protrusions 2 of adjacent sagger bodies 1 in the horizontal direction abut against each other, and a second flow channel 4 is formed between adjacent side plates 11.

[0039] In this embodiment, the sintering sagger provided is used for multi-layer sintering operations, where at least two saggers are stacked vertically. Because a groove 111 is provided at the top of the side wall, a first flow channel 3 is formed between the groove 111 of the lower sagger 1 and the bottom of the upper sagger 1. This allows the gas generated during sintering in the lower sagger 1 to be discharged promptly, preventing the material in the lower sagger 1 from being affected. Simultaneously, the groove 111 reduces the contact area between the upper and lower saggers 1, reducing the possibility of adhesion. In the horizontal direction, multiple... The sintering saggers 1 are arranged sequentially, with the protrusions 2 of adjacent saggers 1 abutting each other, avoiding contact between the side walls of adjacent saggers 1. This effectively reduces the contact area of ​​the side plates 11 of adjacent saggers 1 and creates a second flow channel 4 between adjacent saggers 1 in the horizontal direction. This allows air to fully enter between the saggers 1, preventing excessive temperature due to lack of air circulation between adjacent saggers 1, and thus effectively reducing the possibility of adhesion between adjacent side plates 11. Even if adhesion occurs between the protrusions 2 of saggers 1, the small contact area reduces the difficulty of separation, thereby reducing labor intensity and improving production efficiency. This sintering sagger can form a first flow channel 3 and a second flow channel 4 when stacked, ensuring that the gas generated by the battery material inside the sintering sagger 1 can be smoothly discharged, while reducing the possibility of adhesion between adjacent saggers 1.

[0040] In one embodiment, the casing 1 further includes a bottom plate 12. The casing 1 is provided with four side plates 11, and the four side plates 11 and the bottom plate 12 surround to form a receiving cavity. The battery material is placed in the receiving cavity. During sintering, the battery material in the receiving cavity will generate a large amount of gas. This gas needs to be discharged from the receiving cavity in time to ensure that the pressure of the battery material during the reaction remains unchanged, thereby ensuring the quality of the material. The second flow channel 4 formed by the protrusion 2 can improve air circulation, reduce temperature, and reduce the contact area between the side plates 11 of adjacent casing 1, thereby effectively reducing adhesion.

[0041] In one embodiment, the base plate 12, side plate 11, and protrusion 2 are all made of ceramic. The base plate 12 and side plate 11 are integrally sintered, resulting in high structural strength, resistance to damage and deformation, and high temperature resistance, which ensures the sintering quality of the battery materials during the sintering process.

[0042] In one embodiment, the bottom corners on both sides of the groove 111 are rounded. The rounded bottom corners can enhance the structural strength of the groove 111, eliminate stress concentration, prevent damage to the lower crucible when the casing 1 is stacked, and ensure the production yield of battery materials.

[0043] In one embodiment, the side plate 11 is provided with a groove 111, which is elongated and can expand the ventilation area of ​​the first flow channel 3. At the same time, the process is simple and the manufacturing difficulty is low.

[0044] In one embodiment, the side plate 11 is provided with a plurality of grooves 111, which are spaced apart. This maintains airflow while increasing the support capacity of the side plate 11, ensuring structural stability and preventing damage when stacking the housing 1.

[0045] In one embodiment, the side plate 11 further includes a support portion 112, which is formed on both sides of the groove 111 and abuts against the bottom of the upper casing 1. The top of the side plate 11 is recessed downward to form a groove 111, and then the support portion 112 is formed on both sides of the groove 111 to support the upper casing 1. The structure is simple and easy to manufacture.

[0046] In one embodiment, a limiting part (not shown in the figure) is provided at the bottom of the casing 1, which is adapted to engage with the support part 112. By engaging the limiting part with the support part 112, the connection of the casings 1 stacked in the vertical direction can be made more stable, and the casing 1 located on the top can be prevented from moving or shaking.

[0047] In one embodiment, the protrusion 2 includes a first part 21, which is in the shape of a straight line and extends horizontally along its length. Two opposing first parts 21 between adjacent housings 1 are adapted to abut together to form a second flow channel 4. The horizontal extension of the first part 21 reduces the difficulty of aligning the two housings 1. Even if there is some misalignment between the two adjacent housings 1 in the horizontal direction, the first flow channel 3 can be formed by at least part of the abutment of the two first parts 21, ensuring air circulation.

[0048] In one embodiment, the protrusion 2 further includes a second part 22, which is in the shape of a straight line and is perpendicular to the first part 21. When the two first parts 21 of adjacent housing 1 abut, the two second parts 22 can also abut. The second part 22 is perpendicular to the first part 21, thereby ensuring that even if the two adjacent housing 1 are misaligned in the vertical direction, at least a portion of the two second parts 22 can still abut to form the second flow channel 4, further ensuring the flow of air.

[0049] In one embodiment, the protrusion 2 is cross-shaped. The cross-shaped protrusion 2 can reduce the impact of misalignment of the housing 1 in the vertical and horizontal directions, ensure the formation of the second flow channel 4, ensure air flow, and the cross-shaped protrusion 2 occupies a small area, reducing the possibility of protrusion 2 sticking together.

[0050] In one embodiment, the protrusion 2 is circular (not shown). The circular protrusion 2 can also reduce the impact of misalignment of the sintering sagger 1 in both the vertical and horizontal directions, ensure the formation of the second flow channel 4, ensure air flow, and at the same time, the circular protrusion 2 is easy to process, reducing the manufacturing difficulty of the sintering sagger.

[0051] In other embodiments, the protrusion 2 can also be configured into other shapes as needed, such as triangles, rectangles, etc.

[0052] In one embodiment, a plurality of protrusions 2 are provided, and the plurality of protrusions 2 are spaced apart along the length direction of the side plate 11. The spaced arrangement of the plurality of protrusions 2 along the length direction of the side plate 11 can make the connection between the various housings 1 more stable, allow the second flow channel 4 to flow air stably, and further reduce the possibility of adhesion.

[0053] In this embodiment, three protrusions 2 are provided. In other embodiments, the number of protrusions 2 can be set according to the size of the box body 1.

[0054] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
