Description

Technical Field

[0001] The utility model relates to the field of auxiliary tools for lithium battery production, in particular to a baking crucible for lithium battery materials. Background Art

[0002] For the sintering of existing lithium battery cathode materials, the materials need to be loaded into a crucible, and the crucible is placed in a sintering furnace to sinter the materials at high temperature.

[0003] Existing crucibles, such as a crucible for roller hearth kiln sintering of lithium-ion ternary cathode materials disclosed in Chinese Patent CN215002867U, set a ventilation pipe in the center of the crucible body to solve the problem of poor oxygen atmosphere of the raw materials to be burned in the lower layer. However, such a setting still has certain problems:

[0004] First: The raw materials to be burned are in direct contact with the bottom of the crucible body, and the contact area is large. There is no ventilation structure at the bottom of the crucible body. Therefore, there is still a problem of poor oxygen atmosphere in the part in contact with the bottom of the crucible body.

[0005] Second: When the crucibles are stacked and used, ventilation is only through the notches at the top of the crucible body, and the ventilation is poor. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a baking crucible for lithium battery materials.

[0007] The innovation point of the utility model lies in that: the crucible structure designed in this application is scientific and reasonable, with uniform oxygen distribution, good ventilation effect, good baking effect and high efficiency.

[0008] To achieve the above-mentioned utility model purpose, the technical solution of the utility model is:

[0009] A baking crucible for lithium battery materials, including a crucible body. The crucible body includes a crucible bottom and crucible walls arranged around the crucible bottom. Convex support platforms are respectively arranged at four corners on the front of the crucible bottom. A firing hole plate matching the shape of the crucible bottom is arranged on the support platform. A cavity is formed between the firing hole plate and the crucible bottom. A first notch is arranged at the top of the crucible wall, and a second notch is arranged at the bottom of the crucible wall. The second notch is communicated with the cavity. L-shaped support columns are respectively arranged at four corners on the back of the crucible bottom. Clamping grooves matching the four corners of the top of the crucible body are arranged at the bottoms of the support columns. The support columns extend towards the outside of the crucible wall to form extension parts. During use, a plurality of the crucible bodies are arranged adjacent to each other front, back, left and right, and an air passage is formed between two adjacent crucible walls.

[0010] Further, positioning rods are also arranged on the support platforms, and positioning holes corresponding to the positioning rods are arranged at four corners of the firing hole plate.

[0011] Further, a first partition board and a second partition board are also arranged in the crucible body to divide the crucible body into several material spaces.

[0012] Further, both ends of the first partition board are respectively inserted into the grooves on the inner walls of two opposite bowl walls, a bayonet is arranged on one side of the second partition board, and the second partition board is clamped on the first partition board and can slide along the first partition board.

[0013] The beneficial effects of the utility model are as follows:

[0014] First: In this application, a bearing firing hole plate is provided. The contact area between the raw material to be fired and the bearing firing hole plate is small. A cavity is formed between the bearing firing hole plate and the bottom of the bowl. A second notch is arranged at the bottom of the bowl wall, and the second notch communicates with the cavity. This design can ensure the uniformity of the oxygen atmosphere distribution inside the bowl during roasting, especially the uniformity of the oxygen atmosphere distribution at the bottom of the raw material to be fired, and guarantee the quality of roasting.

[0015] Second: The support columns extend towards the outer side of the bowl wall to form extension parts. When the bowls are arranged side by side in the front, back, left, and right directions, due to the existence of the extension parts, a ventilation channel is formed between two adjacent bowl walls; therefore, the ventilation effect of this application is good, and the roasting efficiency can be ensured.

[0016] Third: In this application, a first partition board and a second partition board are arranged to divide the inside of the bowl into several material spaces. And because the second partition board can move along the first partition board, the size of the material space can be adjusted, and different materials can be prevented from being mixed and contaminated with each other during roasting.
