Description

Technical Field

[0001] This utility model belongs to the field of lithium nickel cobalt manganese oxygen ternary materials, and specifically relates to a heat treatment device for the production of lithium nickel cobalt manganese oxygen ternary materials. Background Technology

[0002] Lithium-nickel-cobalt-manganese-oxygen (NCM) ternary materials, typically referring to lithium nickel cobalt-manganese oxide (LCM) cathode materials, are composite oxide materials used in lithium-ion batteries. These materials are composed of nickel, cobalt, and manganese. Ternary materials offer advantages such as high energy density, high voltage, and low cost, making them widely used in power lithium batteries. Nickel in NCM materials primarily contributes to increasing the battery's energy density, while cobalt stabilizes the layered structure and improves cycle performance. Although manganese does not directly contribute to specific capacity, it helps maintain the material's structural stability. A water bath heat treatment device is used before the ternary material is applied.

[0003] Chinese Patent No. CN211659963U discloses a heat treatment device for the production of lithium nickel cobalt manganese oxygen ternary materials. The device includes a base, with two vertical plates and a heating assembly fixedly connected to the base surface. A first motor is fixedly connected to a lead screw shaft, and a lifting mechanism is threaded through the outer wall of the lead screw. The lifting mechanism includes a moving block threaded to the lead screw, a lifting rod slidably connected to the inner wall of a groove, a rack fixedly connected to the side wall of the lifting rod, and a second motor fixedly connected to the side wall of the moving block. The transmission shaft of the second motor extends into the interior of an opening and is connected to a gear. This invention relates to the field of lithium nickel cobalt manganese oxygen ternary material production technology. This invention solves the problem that in the production process of lithium nickel cobalt manganese oxygen ternary materials, water bath heating of raw materials is required, but the heating process necessitates multiple workers to cooperate in lifting the container containing the raw materials, resulting in very high labor intensity and low work efficiency.

[0004] As can be seen from the above structure, the lifting rod is driven to move upward, lift the container, and then the lifting mechanism is driven to move and lower the container onto the base. This heat treatment device for the production of lithium nickel cobalt manganese oxygen ternary materials reduces manpower input and labor intensity. However, during use, the ternary material container needs to be lifted before moving, which may cause the ternary material container to shake during use. This may lead to excessive pressure on the guide rod during the movement, resulting in damage to the connection. Under prolonged negative pressure support, the device may be damaged.

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a heat treatment device for the production of lithium-nickel-cobalt-manganese-oxygen ternary materials, so as to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A heat treatment apparatus for producing lithium-nickel-cobalt-manganese-oxygen ternary materials includes a base frame, a support plate fixedly connected to the upper end of the base frame, a lifting assembly fixedly connected to the upper end of the support plate, a limit assembly provided on the inner side of the upper end of the support plate, and movable assemblies provided on both sides of the base frame. Each movable assembly includes movable slots provided on both sides of the base frame, a movable screw rotatably connected inside the movable slots, a driven bevel gear fixedly connected to one end of the movable screw, a threaded component threadedly connected to the outer surface of the movable screw, a mounting plate fixedly connected to the inner side of each threaded component, and a treatment tank fixedly connected to the upper end of the mounting plate.

[0008] As a preferred technical solution, a mobile motor is fixedly connected to the upper end of the base frame, and a bidirectional gearbox is fixedly connected to the output shaft of the mobile motor. A connecting shaft is fixedly connected to the output shaft of the bidirectional gearbox, and a driving bevel gear is fixedly connected to the other end of the connecting shaft. The driving bevel gear and the driven bevel gear are meshed with each other.

[0009] As a preferred technical solution, the lifting assembly includes a through hole at the upper end of the support plate. The upper end of the support plate is fixedly connected to both sides of the through hole. A winding reel is rotatably connected to the inner side of each support. A lifting motor is fixedly connected to one side of the support. The output shaft of the lifting motor passes through the support and is fixedly connected to the winding reel. A steel wire rope is wound on the outer surface of the winding reel. A hook is fixedly connected to the other end of the steel wire rope.

[0010] As a preferred technical solution, both sides of the treatment pool are fixedly connected to fixed edges, and fixed holes are opened on the surface of each fixed edge. Fixed screws are inserted into the fixed holes, and the fixed screws pass through the fixed holes and are threadedly connected to the mounting plate.

[0011] As a preferred technical solution, the limiting component includes limiting grooves located on both sides of the lifting component at the lower end of the support plate. A limiting screw is rotatably connected inside the limiting groove. A movable part is threadedly connected to the outer surface of the limiting screw. A connecting rod is fixedly connected to the lower end of the movable part. A limiting plate is fixedly connected to the lower end of the connecting rod. Limiting motors are fixedly connected to both sides of the support plate. The output shaft of the limiting motor passes through the support plate and is fixedly connected to the limiting screw.

[0012] As a preferred technical solution, the connecting rod includes a limiting sleeve rod disposed at the lower end of the moving part, and the lower end of the limiting sleeve rod is provided with an insertion hole, into which a limiting movable rod is inserted.

[0013] As a preferred technical solution, the insertion hole and the limiting movable rod are slidably connected to each other, the insertion hole has a limiting groove inside, the upper end of the limiting movable rod is fixedly connected to a limiting slider, and the limiting slider and the limiting groove are slidably connected to each other.

[0014] In summary, the present invention has the following main advantages:

[0015] Firstly, this utility model, through its movable component, first moves the hook downwards via the lifting component to hang the ternary material container, then lifts the container up. Next, the movable motor controls the bidirectional gearbox to rotate, which in turn rotates the connecting shaft. This rotation of the connecting shaft causes the driving bevel gear to rotate, which in turn drives the driven bevel gear. The driven bevel gear then rotates the movable screw, causing the threaded component to move on the surface of the screw. This movement of the threaded component moves the mounting plate, which in turn moves the processing tank to the lower end of the ternary material container. Finally, the ternary material container is lowered via the lifting component, allowing for heat treatment inside the processing tank. This design minimizes movement and reduces damage to the device during container movement.

[0016] Secondly, this utility model, through its lifting and limiting components, allows for the hook to be attached to the ternary material container during use. The lifting motor is then activated, causing the winding reel to rotate. The winding reel winds up the wire rope, causing the hook to move upwards, thus lifting the ternary material container. Before lifting, after attaching the hook, the limiting motor is controlled to rotate, causing the limiting screw to rotate. This, in turn, causes the connecting rods to move closer together, which in turn causes the limiting plate to move closer together. This effectively limits the movement of the ternary material container during lifting, preventing it from swaying. Attached Figure Description

The output shaft of the bidirectional gearbox 57 is fixedly connected with a connecting shaft 58. The other end of the connecting shaft 58 is fixedly connected with a driving bevel gear 59. The driving bevel gear 59 and the driven bevel gear 55 mesh with each other.

[0024] refer to Figure 1 and Figure 2 The lifting component 3 includes a through hole 34 at the upper end of the support plate 2. Supports 31 are fixedly connected to both sides of the through hole 34 at the upper end of the support plate 2. A winding reel 32 is rotatably connected to the inner side of each support 31. A lifting motor 33 is fixedly connected to one side of the support 31. The output shaft of the lifting motor 33 passes through the support 31 and is fixedly connected to the winding reel 32. A steel wire rope 36 is wound around the outer surface of the winding reel 32. A hook 35 is fixedly connected to the other end of the steel wire rope 36. By hooking the hook 35 to the ternary material container and then starting the lifting motor 33 to rotate the winding reel 32, the steel wire rope 36 is wound up, causing the hook 35 to move upward, thereby lifting the ternary material container.

[0025] refer to Figure 1 Both sides of the treatment pool 6 are fixedly connected to fixed edges 7, and fixed holes 8 are opened on the surface of the fixed edges 7. Fixed screws 9 are inserted into the fixed holes 8 and are threaded through the fixed holes 8 to the mounting plate 54. The fixed screws 9 enable the treatment pool 6 to be installed, and the installation method of the fixed screws 9 makes disassembly more convenient.

[0026] refer to Figures 1-3 The limiting component 4 includes limiting grooves 41 located on both sides of the lifting component 3 at the lower end of the support plate 2. A limiting screw 42 is rotatably connected inside the limiting groove 41. A moving part 43 is threadedly connected to the outer surface of the limiting screw 42. A connecting rod 44 is fixedly connected to the lower end of the moving part 43. A limiting plate 45 is fixedly connected to the lower end of the connecting rod 44. Limiting motors 46 are fixedly connected to both sides of the support plate 2. The output shaft of the limiting motor 46 passes through the support plate 2 and is fixedly connected to the limiting screw 42. After the hook 35 is attached before lifting, the limiting motor 46 can be controlled to rotate, thereby driving the limiting screw 42 to rotate. Under the action of the moving part 43, the connecting rod 44 is driven to move closer together. When the connecting rod 44 moves closer together, the limiting plate 45 moves closer together, thereby limiting the ternary material container during lifting and preventing the ternary material container from shaking.

[0027] refer to Figure 2 and Figure 3 The connecting rod 44 includes a limiting sleeve 441 disposed at the lower end of the moving part 43. The lower end of the limiting sleeve 441 has an insertion hole 442, and a limiting movable rod 443 is inserted into the insertion hole 442. The insertion hole 442 and the limiting movable rod 443 are slidably connected to each other. A limiting groove 10 is provided inside the insertion hole 442. A limiting slider 11 is fixedly connected to the upper end of the limiting movable rod 443. The limiting slider 11 and the limiting groove 10 are slidably connected to each other. The limiting sleeve 441 and the limiting movable rod 443 make it easy to adjust the distance of the connecting rod 44, making it more convenient to use. Under the action of the limiting groove 10 and the limiting slider 11, the limiting sleeve 441 and the limiting movable rod 443 are prevented from disengaging.

[0028] Operating principle and advantages: First, the device is placed in a suitable position, and then the treatment tank 6 is installed using the fixing screws 9. The fixing screws 9 also make disassembly easier. After installation, the ternary material container is placed inside the support plate 2, and then the hook 35 is attached to the ternary material container. The lifting motor 33 is then started, causing the winding reel 32 to rotate. Under the action of the winding reel 32, the wire rope 36 is wound up, causing the hook 35 to move upward, thus lifting the ternary material container. Before lifting, after the hook 35 is attached, the limit motor 46 is controlled to rotate, causing the limit screw 42 to rotate. Under the action of the moving part 43, the connecting rod 44 is pulled together, thus allowing the connecting rod 44 to move together. When the components approach, the limiting plate 45 moves closer, thus limiting the movement of the ternary material container during lifting to prevent it from shaking. Then, the moving motor 56 can be controlled to rotate the bidirectional gearbox 57, which in turn rotates the connecting shaft 58. The rotation of the connecting shaft 58 causes the driving bevel gear 59 to drive the driven bevel gear 55 to rotate. The rotation of the driven bevel gear 55 causes the moving screw 52 to rotate, which in turn causes the threaded part 53 to move on the surface of the moving screw 52. The movement of the threaded part 53 causes the mounting plate 54 to move, which in turn moves the processing pool 6 to the lower end of the ternary material container. Then, the ternary material container is lowered by the lifting component 3, and heat treatment can be performed inside the processing pool 6, thus facilitating the processing of the ternary material container.
