Description

Technical Field

[0001] This utility model relates to the field of drying device technology, specifically to a material drying device. Background Technology

[0002] Ternary cathode materials refer to materials used in the cathode of lithium-ion batteries. They are mainly composed of elements such as nickel (Ni), cobalt (Co), and manganese (Mn) or aluminum (Al), and the most common types are NCM (nickel-cobalt-manganese) and NCA (nickel-cobalt-aluminum). These materials are crucial for the energy density, cycle life, and safety of lithium-ion batteries.

Its purpose is to remove moisture or other solvents from the ternary cathode materials to ensure the quality of the final product. In practice, if the materials are piled up in the drying equipment and cannot be stirred to disperse them, the materials cannot be heated evenly, resulting in a poor drying rate and unsatisfactory drying effect.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] To address the technical problem in existing technologies where material accumulation during drying leads to uneven heating and poor drying results, this invention provides a material drying device that can disperse accumulated materials, ensuring uniform heating.

[0023] Please see Figures 1-4 , Figures 1-4 A material drying device according to one embodiment of the present invention includes a drying furnace 1, a heating mechanism 2, a rotating mechanism 3, and a material feeding mechanism 4. The drying furnace 1 has a drying chamber. The heating mechanism 2 is connected to the drying furnace 1 and is used to raise the temperature inside the drying chamber. The rotating mechanism 3 includes a driving member 31 and a material tray 32. The driving member 31 is connected to the drying furnace 1. The material tray 32 is disposed inside the drying chamber and connected to the output end of the driving member 31. The driving member 31 is used to drive the material tray 32 to rotate around a central axis, and the material tray 32 has an upward-opening feeding groove 32a. The fixed end of the material feeding mechanism 4 is fixed inside the drying chamber, and the movable end of the material feeding mechanism 4 has a plurality of distributing teeth 40 arranged radially along the material tray 32, and the plurality of distributing teeth extend into the feeding groove 32a.

[0024] In this specific embodiment, the material to be dried is a ternary cathode material. To facilitate the material's delivery into the discharge trough 32a, a guide pipe 11 is specifically provided inside the drying chamber. The upper end of the guide pipe 11 is connected to the feed inlet at the top of the drying furnace 1, and the lower end of the guide pipe 11 extends into the discharge trough 32a. Furthermore, a control valve is provided at the feed inlet.

[0025] It should be noted that when the ternary cathode material is conveyed to the discharge tank 32a through the feed pipe 11, the feed tray 32 needs to be driven to rotate around the central axis by the drive component 31 to avoid the ternary cathode material from accumulating too high in the discharge tank 32a.

[0026] In this specific embodiment, the heating mechanism 2 consists of multiple heating blocks, which are fixedly disposed at intervals along the circumference of the material tray 32 on the inner side wall of the drying oven 1, and the drying chamber is heated by the multiple heating blocks.

[0027] In this specific embodiment, the driving component 31 includes a geared motor 311 and a transmission shaft 312. The geared motor 311 is fixedly mounted on the top of the drying oven 1. The output end of the geared motor 311 is fixedly connected to one end of the transmission shaft, and the other end of the transmission shaft 312 is fixedly connected to the center of the material tray 32. Specifically, the geared motor 311 drives the transmission shaft 312 to rotate, thereby driving the material tray 32 to rotate.

[0028] Specifically, the material feeding mechanism 4 includes a connecting rod 41, one end of which is fixedly connected to the inner wall of the drying oven 1. The connecting rod 41 is located above the material tray 32, and multiple material separating teeth 40 are spaced apart on the connecting rod 41. When the material tray 32 rotates, the multiple material separating teeth 40 can separate the ternary cathode material, ensuring that the ternary cathode material is heated evenly during drying.

[0029] Based on the above scheme, in order to facilitate the discharge of the ternary cathode material from the drying chamber, specifically,

[0030] It also includes a discharge mechanism 5, which includes a telescopic component 51, a linkage plate 52, a discharge pipe 53, and a suction hood 54. The telescopic component 51 is fixed to the top of the drying oven 1, and the output end of the telescopic component 51 is fixedly connected to the linkage plate 52. One end of the discharge pipe 53 is fixedly connected to the linkage plate 52, and the other end of the discharge pipe 53 extends into the drying chamber and is connected to the suction hood 54. The telescopic component 51 is used to drive the suction hood 54 to move into / out of the discharge trough 32a.

[0031] It should be noted that the discharge pipe 53 is connected to the air extraction device, and the air extraction device can extract the ternary cathode material in the discharge trough 32a by evacuating the suction hood 54. The discharge pipe 53 is a corrugated hose, and the suction hood 54 is arranged along the radial direction of the material tray 32.

[0032] In this specific embodiment, the telescopic member 51 is an electric push rod. Of course, in other embodiments, the telescopic member 51 can also be a pneumatic cylinder or a hydraulic cylinder.

[0033] It should be noted that an annular gap is formed between the outer wall of the material tray 32 and the inner wall of the drying furnace 1. The lower end of the drying furnace 1 is provided with a discharge port 12, and a discharge valve is provided on the discharge port 12. During the process of the multiple material separating teeth 40 separating the ternary cathode material in the discharge trough 32a, some material will fall into the bottom of the drying furnace 1. By opening the discharge valve, the material can be discharged from the discharge port 12.

[0034] In this specific embodiment, a mounting frame 6 is also included. The mounting frame 6 includes a connecting ring 61 and a plurality of support rods 62. The plurality of support rods 62 are fixedly connected to the connecting ring 61, and the drying oven 1 is fixedly connected to the connecting ring 61.

[0035] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below:

[0036] The ternary cathode material is conveyed to the discharge trough 32a through the guide pipe 11. The geared motor 311 drives the material tray 32 to rotate around its own axis, so that multiple distributing teeth 40 can separate the ternary cathode material to ensure that the ternary cathode material is heated evenly during drying. After the ternary cathode material is dried, the suction hood 54 is moved into the discharge trough 32 by the telescopic component 51. The ternary cathode material can be extracted by evacuating the suction hood 54 through the air extraction component.
