Description

Technical Field

[0001] This utility model relates to a sagger, and more particularly to a modular combined ceramic sagger. Background Technology

[0002] The main purpose of calcining lithium battery materials is to change the chemical and physical properties of the materials through heat treatment in order to obtain the desired performance, such as improving the crystallinity of the materials, improving electrochemical performance, and increasing the stability and conductivity of the materials.

[0003] Lithium-ion batteries need to be placed in a crucible during firing. Existing crucibles are mainly made of mullite. The thermal expansion mismatch between the reaction products of Li₂O and mullite and the crucible material can lead to microcracks, causing the crucible surface to peel off and break. Mullite crucibles are typically discarded after about 20 days of use, resulting in high costs. Furthermore, mullite crucibles have poor load-bearing capacity and cannot be stacked for firing, further contributing to high costs and low efficiency. Utility Model Content

[0004] To address the above problems, this utility model provides a modular combined ceramic sagger, the specific technical solution of which is as follows: A modular ceramic sagger includes: a ceramic column with a vertical slot and a horizontal slot, the vertical slot and the horizontal slot being perpendicular to each other, and two vertical slots; a ceramic base plate disposed within the horizontal slot; and ceramic side plates disposed on both sides within the vertical slots, with one end abutting against the base plate; wherein the base plate and the side plates form a sagger.

[0005] Preferably, both the base plate and the side plate are provided with a plurality of through holes.

[0006] Preferably, the horizontal slot is a through slot.

[0007] Preferably, the horizontal slot communicates with the vertical slot.

[0008] Preferably, it further includes: a shelf, which is disposed inside the sagger and has several fixing slots for fixing items.

[0009] Furthermore, it also includes a column, which is disposed inside the sagger and abuts against the shelf to support the shelf.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides a modular ceramic sagger, which is assembled from ceramic columns, base plates and side plates. It has high overall strength, can be stacked and fired, is not easily reacted with lithium battery materials, has a long service life, greatly improves efficiency and reduces costs.

[0011] A modular ceramic sagger is made of sampled ceramic, which has high overall strength. The modular sagger components can be stacked and sintered separately, improving production efficiency and reducing production costs. It uses high-purity alumina and other impurity-free materials (low silicon content) and is not easily reactive with lithium batteries and electronic materials, ensuring the performance indicators of the synthesized materials.

[0012] The porous design allows the hot airflow from the kiln to be directly conducted into the synthetic material, resulting in more thorough sintering. This reduces the sintering temperature and shortens the high-temperature synthesis time. The sagger is made of high-density ceramic material, which makes it stronger and less susceptible to corrosion from the synthetic material, thus extending its service life. This significantly improves efficiency and reduces costs. Attached Figure Description

Detailed Implementation

[0014] The present invention will now be further described with reference to the accompanying drawings.

[0015] like Figures 1 to 6 As shown, a modular ceramic sagger includes four columns 1, a base plate 3, and side plates 2, all made of ceramic material. Each column 1 has a vertical slot 11 and a horizontal slot 12. The vertical slots 11 are arranged vertically and located on two adjacent faces of the column 1. The horizontal slots 12 are arranged horizontally and perpendicular to the vertical slots 11. The columns 1 can be cubic or cylindrical. A single base plate 3 is inserted into the horizontal slots 12 of the four columns 1. Four side plates 2 are provided, with their two sides inserted into the vertical slots 11 of the columns 1. One end of each side plate 2 rests against the base plate 3. The base plate 3 and the side plates 2 together form the sagger.

[0016] Ceramics have good corrosion resistance, which can ensure service life. In addition, ceramics have high strength and can be stacked for stacked firing, which improves the utilization rate of kilns, reduces firing costs, and improves firing efficiency.

[0017] Furthermore, the assembled structure can be directly replaced if any part of the column 1, base plate 3, or side plate 2 is damaged, without having to scrap the entire sagger, thus reducing the cost of using the sagger.

[0018] The sagger can be made to 320×320mm.

[0019] To improve the efficiency and uniformity of firing, several through holes 4 are provided on both the side plate 2 and the bottom plate 3. The through holes 4 allow hot air from the kiln to quickly enter the interior of the sagger, thereby improving the firing efficiency.

[0020] Through-hole 4 can be arranged in an array.

[0021] like Figure 4 As shown, to facilitate the machining of the horizontal slot 12 and the assembly and disassembly of the base plate 3, the horizontal slot 12 is a through slot. The horizontal slot 12 communicates with the vertical slot 11, allowing the side plate 2 to be directly pressed onto the base plate 3, which simplifies the structure of the side plate 2.

[0022] like Figure 5 and Figure 6 As shown, to facilitate the fixing of the roasted item 6, a shelf 5 is also included. The shelf 5 is placed inside the sagger, and the shelf 5 has fixing slots 51 for fixing the item 6. The fixing slots 51 can be arranged in an array. Furthermore, to facilitate the fixing of the item 6, a column is also included. The column is installed inside the sagger, and its top rests against the shelf 5 to support the shelf 5 and facilitate height adjustment. Both the shelf 5 and the column are made of ceramic.

[0023] This utility model relates to a ceramic sagger, which is assembled from ceramic columns, a base plate, and side plates. It has high overall strength, allows individual stacking and firing of sagger components, and has high production efficiency. The sagger material has high purity and does not react with lithium battery materials, resulting in a long service life. This greatly improves efficiency and reduces costs.

[0024] This ceramic sagger can be used for the production of various powders, various components, and various products that require sagger loading during production.

[0025] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way.
