[0002] Lithium manganese oxide, as a cathode material for lithium-ion batteries, has attracted much attention in the fields of power batteries and energy storage due to its advantages such as low cost, high safety, and environmental friendliness. However, its rapid capacity decay and poor high-temperature cycle performance limit its large-scale application. Currently, lithium manganese oxide products in the industry retain approximately 77% of their capacity and recover about 85% of their capacity after being stored at 60°C for 7 days. However, customers' demands for capacity retention are increasing, making it imperative to improve the capacity retention of materials through process innovation and technological research and development.

[0003] Existing reactors rely on single stirring, which makes high-solids slurry prone to clumping, resulting in high chloride ion mass transfer resistance and a relatively low removal rate. Furthermore, the fixed stirring method cannot adjust the depth, leading to insufficient mixing in the bottom and edge areas of the reactor. Manual opening of the lid and cleaning of the reactor also cause production interruptions, resulting in a capacity loss rate of approximately [missing information]. To address this, we propose a high-solids-content lithium manganese oxide dechlorination reactor. Utility Model Content

[0015] 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. Example

[0016] Please see Figure 1-4 The technical solution provided in this embodiment is as follows: A high-solids-content lithium manganese oxide dechlorination reactor includes: a reactor body 1; a functional mechanism 2 fixedly connected to the surface of the reactor body 1; a feeding mechanism 3 for feeding materials mounted on the front surface of the reactor body 1; the functional mechanism 2 includes a mounting bracket 201 fixedly connected to one side of the reactor body 1; a first electric cylinder 202 for longitudinal adjustment fixedly connected to the surface of the mounting bracket 201; an adjusting bracket 203 fixedly connected to the surface of the piston rod of the first electric cylinder 202; and a sealing cover 204 adapted to the reactor body 1 fixedly connected to the surface of the adjusting bracket 203; the surface of the sealing cover 204 is rotatable. A stirring shaft 205 is connected, and multiple stirring paddles 206 are arranged in a ring array on the surface of the stirring shaft 205. An installation rod 207 is fixedly connected to the bottom of the sealing cover 204. The bottom of the installation rod 207 has a perforated frame 208 located outside the stirring paddles 206. Through the synergistic action of the perforated frame 208 and the stirring paddles 206, the agglomerated materials are directly broken up, the upper limit of the solid content of the slurry is increased, and the energy consumption of subsequent drying is significantly reduced. The sealing cover 204 is designed to open and close with one button, and the guide rod 212 ensures the accuracy of each closure, prevents impurities from entering during the chloride ion reaction process, and improves the purity of the product.

[0017] Specifically, a first servo motor 209 is fixedly connected to the top of the adjusting frame 203. Both the surface of the output shaft of the first servo motor 209 and the surface of the stirring shaft 205 are fixedly connected to pulleys 210, and the two pulleys 210 are rotatably connected through a transmission belt 211.

[0018] In a specific embodiment of this utility model, the first servo motor 209 transmits power to the stirring shaft 205 through the pulley 210 and the transmission belt 211, thereby realizing multi-level speed control of the stirring paddle 206. The transmission belt 211 transmits and buffers the vibration of the first servo motor 209, thus extending the equipment life.

[0019] Specifically, guide rods 212 are fixedly connected to both sides of the adjustment frame 203, and the guide rods 212 are slidably connected to the surface of the mounting frame 201. A blocking ring 213 is fixedly connected to the bottom of the guide rods 212.

[0020] In a specific embodiment of this utility model, the guide rod 212 passes through the mounting bracket 201 and is fixed to the adjusting bracket 203. The bottom blocking ring 213 restricts the stroke, ensuring that the sealing cover 204 rises and falls vertically without deviation. The guide rod 212 eliminates the radial sway of the piston of the first electric cylinder 202, improves the alignment accuracy of the sealing cover 204 and the vessel body 1, and avoids sealing failure or equipment wear.

[0021] Specifically, a baffle rod 214 is fixedly connected to the surface of the sealing cover 204, and two baffle columns 215 are fixedly connected to the surface of the baffle rod 214.

[0022] In a specific embodiment of this utility model, the turbulence rod 214 is used in conjunction with the stirring shaft 205. The turbulence column 215 on its surface generates local turbulence in the slurry. The turbulence column 215 breaks the laminar flow formed by the main stirring, eliminates the mixing dead corner in the inner edge area of ​​the vessel 1, and improves the chloride ion diffusion efficiency.

[0023] Specifically, the feeding mechanism 3 includes a feeding rack 301 fixedly connected to the front surface of the vessel body 1. Two horizontally extending guide rails 302 are fixedly connected to the inner side of the feeding rack 301. A feeding hopper 303 is slidably connected to the surface of the guide rails 302. A feeding pipe 304 is installed at the bottom of the feeding hopper 303. A discharge pipe 305 adapted to the sealing cover 204 is fixedly connected to the lower surface of the feeding pipe 304. A conveying auger 306 is rotatably connected inside the feeding pipe 304. A feeding block 307 located above the discharge pipe 305 is fixedly connected to the surface of the conveying auger 306.

[0024] In a specific embodiment of this utility model, the feeding hopper 303 moves horizontally along the guide rail 302, the second electric cylinder 309 pushes the hopper to position, the conveying auger 306 rotates to propel the material, the material-dispensing block 307 breaks up the clumps above the discharge pipe 305, the conveying auger 306 adapts to high solids content slurry, and the horizontally moving hopper realizes multi-station feeding.

[0025] Specifically, a second servo motor 308 is fixedly connected to the surface of the feeding pipe 304, and the output shaft of the second servo motor 308 is fixedly connected to one end of the conveying auger 306. A second electric cylinder 309 is fixedly connected to the surface of the feeding rack 301, and the piston rod of the second electric cylinder 309 is fixedly connected to the feeding hopper 303.

[0026] In a specific embodiment of this utility model, the second servo motor 308 directly drives the conveying auger 306, and works in conjunction with the second electric cylinder 309 to control the displacement and feeding speed of the hopper 303.

[0027] Working principle: The feeding hopper 303 moves along the guide rail 302 to the top of the reactor body 1. After the second electric cylinder 309 is precisely positioned, the conveying auger 306 pushes the lithium manganese oxide slurry into the discharge pipe 305. The feeding block 307 simultaneously assists in guiding the material to ensure that the material enters the reactor body 1 evenly. The first electric cylinder 202 drives the sealing cover 204 to close. The first servo motor 209 drives the stirring shaft 205 to rotate through the pulley 210. The main stirring paddle 206 applies shearing force to the slurry. At the same time, the hole frame 208 at the end of the mounting rod 207 follows the movement to break up micro-particle clumps, increasing the solid-liquid contact area. The turbulence rod 214 and turbulence column 215 generate turbulence in the reactor wall area, eliminating mixing dead zones. Chloride ions in lithium manganese oxide are released into the liquid phase under the action of mechanical shearing and turbulence, and are removed by subsequent solid-liquid separation. After the reaction is completed, the sealing cover 204 is raised, and the slurry in the reactor is discharged through the bottom valve. The detachable design of the hole frame 208 facilitates the cleaning of residues and reduces cross-contamination.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
