Description

Technical Field

[0001] This utility model belongs to the field of vacuum system technology, and in particular relates to a vacuum dryer for the production of positive electrode materials. Background Technology

[0002] Vacuum dryers for cathode material production are specialized equipment used in the production process of lithium-ion battery cathode materials. Their main function is to remove moisture and solvents from the cathode materials through a heating process in a vacuum environment, ensuring the purity and performance stability of the materials.

[0003] According to the published patent CN216924919U, a vacuum dryer for the production of ternary ring lithium batteries solves the problem that in existing vacuum dryers on the market, the lubricating oil between gears is rapidly depleted after prolonged use. To ensure the normal operation of the equipment, personnel need to frequently disassemble the outer shell for oiling, which is time-consuming, labor-intensive, increases the workload of personnel, and reduces the continuous productivity of the device. The new vacuum dryer for ternary ring lithium battery production includes two support plates, with a vacuum drying mechanism vertically arranged between the two support plates. Round rods are fixedly connected to both sides of the vacuum drying mechanism. This invention avoids the need for frequent disassembly of the outer shell for oiling, saving time and labor, reducing the workload of personnel, and improving the continuous productivity of the device. However, it still has the following shortcomings:

[0004] When heating and drying materials in a vacuum dryer for cathode material production, the accumulation of materials within the device may cause uneven heating, and local overheating may lead to changes or damage to the material properties. Therefore, we propose a vacuum dryer for cathode material production. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum dryer for the production of cathode materials. The dryer uses a motor to rotate the rotating shaft, which in turn drives a gear to rotate. The gear then drives the drum to rotate through a transmission, thus solving the problem of uniform heating of the material.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a vacuum dryer for the production of positive electrode materials, including a support frame, a connecting shell fixedly connected to the top of the support frame, a drying mechanism provided on the connecting shell, and an installation mechanism provided on the support frame;

[0008] The drying mechanism includes a motor frame, a motor fixedly connected to the inner wall of the motor frame, a rotating shaft fixedly connected to the output shaft of the motor via a coupling, a limiting block 1 rotatably connected to the outer surface of the rotating shaft, a gear 1 fixedly connected to the end of the rotating shaft away from the motor, a gear 2 meshing with the outer surface of the gear 1, a rotating block 1 fixedly connected to the outer surface of the gear 2, a limiting block 2 rotatably connected to the outer surface of the rotating block 1, a connecting block slidably connected to the outer surface of the rotating block 1, a closed disc fixedly connected to the outer surface of the connecting block, a roller slidably connected to the outer surface of the closed disc, a rotating block 2 rotatably connected to the inner wall of the limiting block 2, and a heater fixedly connected to the inner wall of the connecting shell.

[0009] Furthermore, the bottom of the motor frame is fixedly connected to the top of the support frame, the bottom of the first limiting block is fixedly connected to the top of the support frame, the outer surface of the first rotating block is rotatably connected to the inner wall of the connecting shell, and two limiting blocks are provided in total.

[0010] Furthermore, the bottom of the limiting block two is fixedly connected to the inner wall of the connecting shell, and there are two connecting blocks in total. The outer surface of the roller is fixedly connected to the outer surface of the connecting block, and the outer surface of the rotating block two is slidably connected to the outer surface of the connecting block.

[0011] Furthermore, the installation mechanism includes a closed door rotatably connected to the inner wall of the connecting shell, an installation frame fixedly connected to the top of the support frame, an air extractor slidably connected to the inner wall of the installation frame, and a connecting pipe fixedly connected to the inner wall of the air extractor.

[0012] Furthermore, the outer surface of the connecting pipe is fixedly connected to the inner wall of the connecting shell, and a connecting block is fixedly connected to the side of the closed disc near the motor. A total of several connecting blocks are provided, and a fixing column is fixedly connected to the outer surface of the connecting block.

[0013] Furthermore, a C-ring is slidably connected to the outer surface of the fixed column, a moving plate is fixedly connected to the outer surface of the C-ring, and a rotating drum is fixedly connected to the end of the moving plate away from the C-ring.

[0014] Furthermore, a connecting shaft is fixedly connected to the inner wall of the rotating drum, and a connecting block two is rotatably connected to the outer surface of the connecting shaft. The outer surface of the connecting block two is fixedly connected to the outer surface of the drum.

[0015] Furthermore, an extension plate is fixedly connected to the outer surface of the second connecting block, and a bolt is threadedly connected to the inner wall of the extension plate, with the outer surface of the bolt threadedly connected to the inner wall of the connecting shaft.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates a roller. The motor causes the rotating shaft to rotate, which in turn drives gear one to rotate. Gear one then drives gear two to rotate, which in turn drives rotating block one to rotate within limiting block two. Rotating block one then drives the connecting block to rotate. Through the connecting block that drives the roller to rotate, the material can be tumbled inside the roller, resulting in uniform heating. This effectively prevents the material from being underheated or overheated in certain areas, ensuring uniform evaporation of moisture and avoiding changes or damage to material properties due to localized overheating.

[0018] 2. This utility model incorporates a moving plate. Bolts are unscrewed from the connecting shaft and extension plate, and then the moving plate rotates away from each other. This causes the connecting shaft to rotate within the connecting block two, and simultaneously moves the C-ring, removing it from the fixed post. The moving plate, which can be secured to the fixed post, facilitates the removal of the roller from the device, enabling efficient material collection and removal of dried materials from the equipment. This, in turn, accelerates the production cycle and improves overall production efficiency.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-8 As shown, this utility model is a vacuum dryer for the production of positive electrode materials, including a support frame 101, a connecting shell 102 fixedly connected to the top of the support frame 101, a drying mechanism 2 provided on the connecting shell 102, and an installation mechanism 3 provided on the support frame 101.

[0033] The drying mechanism 2 includes a motor frame 201. First, the material is tumbled and uniformly heated and dried within the connecting shell 102 by the drying mechanism 2. Then, the dried material is collected by the mounting mechanism 3. A motor 202 is fixedly connected to the inner wall of the motor frame 201. The output shaft of the motor 202 is fixedly connected to a rotating shaft 203 via a coupling. A limit block 204 is rotatably connected to the outer surface of the rotating shaft 203. A gear 205 is fixedly connected to the end of the rotating shaft 203 away from the motor 202. The motor frame 201 fixes the position of the motor 202 to prevent the motor 202 from rotating during operation, which would affect the transmission of the device. Gear 206 meshes with the outer surface of gear 1 205. A rotating block 207 is fixedly connected to the outer surface of gear 206. A limiting block 208 is rotatably connected to the outer surface of rotating block 207. A connecting block 209 is slidably connected to the outer surface of rotating block 207. Gear 1 205 drives gear 206 to rotate, and then gear 206 drives rotating block 207 to rotate within the limiting block 208. At this time, the limiting block 208 restricts the position of rotating block 207 to prevent it from shifting during rotation. A sealing disk 210 is fixedly connected to the outer surface of connecting block 209, and a roller is slidably connected to the outer surface of sealing disk 210. 211, a rotating block 213 is rotatably connected to the inner wall of the limiting block 208, and a heater 212 is fixedly connected to the inner wall of the connecting shell 102. The connecting block 209 can drive the closed disc 210 to rotate, and then the closed disc 210 drives the roller 211 to rotate through the parts in the mounting mechanism 3, so that the material rolls and is heated evenly inside the roller 211. The bottom of the motor frame 201 is fixedly connected to the top of the support frame 101, the bottom of the limiting block 204 is fixedly connected to the top of the support frame 101, and the outer surface of the rotating block 207 is rotatably connected to the inner wall of the connecting shell 102. There are two limiting blocks 208. The gear 206 drives the rotating block 212 to rotate. When block 1 207 rotates, it will rotate inside the connecting shell 102, thus enabling the next transmission and allowing the device to work normally. The bottom of the limiting block 208 is fixedly connected to the inner wall of the connecting shell 102. There are two connecting blocks 209. The outer surface of the roller 211 is fixedly connected to the outer surface of the connecting block 209, and the outer surface of the rotating block 213 is slidably connected to the outer surface of the connecting block 209. The connecting block 209 can be removed from the rotating block 213, and at the same time, the connecting block 209 can also slide out from the rotating block 207, thereby removing the roller 211 from the device and collecting the dried material inside.

[0034] The mounting mechanism 3 includes a closed door 301 rotatably connected to the inner wall of the connecting shell 102. A mounting frame 302 is fixedly connected to the top of the support frame 101. A vacuum pump 303 is slidably connected to the inner wall of the mounting frame 302. A connecting pipe 304 is fixedly connected to the inner wall of the vacuum pump 303. The vacuum pump 303 can be activated to evacuate the interior of the connecting shell 102 to a vacuum, allowing the material to evaporate moisture and solvent at a lower temperature, thus avoiding damage to the structure and performance of the positive electrode material from high temperatures. The outer surface of the connecting pipe 304 is fixedly connected to the inner wall of the connecting shell 102. A connecting block 305 is fixedly connected to the side of the closed disc 210 near the motor 202. Several connecting blocks 305 are provided. 5. A fixed post 306 is fixedly connected to the outer surface of the device. The connecting block 305 fixes the position of the fixed post 306. When the closed disc 210 rotates, it can drive the roller 211 to rotate through the fixed post 306, so that the material can tumble inside the roller 211. A C-ring 307 is slidably connected to the outer surface of the fixed post 306. A moving plate 308 is fixedly connected to the outer surface of the C-ring 307. A rotating drum 309 is fixedly connected to the end of the moving plate 308 away from the C-ring 307. The C-ring 307 can be tightly locked on the fixed post 306, so that when the closed disc 210 rotates, it can drive the roller 211 to rotate through the fixed post 306 and the C-ring 307, so that the device can operate normally.

[0035] A connecting shaft 310 is fixedly connected to the inner wall of the rotating drum 309. A connecting block 311 is rotatably connected to the outer surface of the connecting shaft 310. The outer surface of the connecting block 311 is fixedly connected to the outer surface of the drum 211. The C-ring 307 can be rotated by the moving plate 308, so that the C-ring 307 is disengaged from the fixed column 306, thereby allowing the connecting block 311 to be removed from the device and the dried material inside the drum 211 to be collected. An extension plate 312 is fixedly connected to the outer surface of the connecting block 311. A bolt 313 is threadedly connected to the inner wall of the extension plate 312. The outer surface of the bolt 313 is threadedly connected to the inner wall of the connecting shaft 310. The position of the connecting shaft 310 can be fixed by the bolt 313, so that the sealing disc 210 will not loosen from the drum 211 when the drum 211 rotates, so that the device can work normally.

[0036] One specific application of this embodiment is:

[0037] When the operator needs to use the equipment, firstly, the vacuum pump 303 is started to evacuate the inside of the connecting shell 102 to a vacuum state. Then, the heater 212 and the motor 202 are started. At this time, the heater 212 will heat the inside of the connecting shell 102, and then the motor 202 will cause the rotating shaft 203 to rotate. After that, the rotating shaft 203 will drive the gear one 205 to rotate, and then the gear one 205 will drive the gear two 206 to rotate. At this time, the gear two 206 will drive the rotating block one 207 to rotate within the limiting block two 208, and then the rotating block one... 207 will drive the connecting block 209 to rotate, and then the connecting block 209 will drive the roller 211 to rotate through the enclosed disk 210. At the same time, the roller 211 will also drive the rotating block 213 to rotate within the limiting block 208 through the connecting block 209. This allows the material to tumble and be heated evenly within the roller 211, effectively preventing insufficient or excessive heating in certain areas, ensuring uniform evaporation of moisture, and avoiding changes in material properties due to localized overheating. To mitigate the damage, when the material needs to be collected after drying, the closed door 301 can be opened inside the connecting shell 102. Then, the screws connecting the rotating block 207 and the connecting block 209, as well as the screws connecting the connecting block 209 and the rotating block 213, can be unscrewed. At this point, the roller 211 can be removed from the device as a whole. Then, the bolts 313 can be unscrewed from the connecting shaft 310 and the extension plate 312. Then, the moving plate 308 can be rotated away from each other. At this time, the moving plate 308 will drive the connecting shaft 310 to rotate the connecting block 213. When the inner rotation is complete, the moving plate 308 will drive the C buckle 307 to move, thereby removing the C buckle 307 from the fixed column 306. At this time, the closed disc 210 can be pulled away from the roller 211, so that the closed disc 210 is separated from the roller 211, and then the material inside the roller 211 can be collected. This makes it easy to remove the roller 211 from the device, thus facilitating the collection of materials. It can efficiently remove the dried materials from the equipment, thereby speeding up the production cycle and improving the overall production efficiency.
