Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium cobalt oxide processing, specifically a multi-stage sorting device for lithium cobalt oxide raw materials. Background Technology
[0002] Lithium cobalt oxide, generally referring to lithium cobalt oxide, is an inorganic compound and a relatively good cathode material in lithium-ion batteries. It has advantages such as high operating voltage, stable discharge, high specific energy, and good cycle performance. However, it is expensive (due to the use of cobalt), has poor safety, average cycle life, and relatively poor material stability.
[0003] In the preparation process of lithium cobalt oxide raw materials, solid-phase synthesis is the most mainstream process. Other methods include sol-gel method and co-precipitation method. In these methods, solid powders of cobalt source and lithium source are mixed and reacted at high temperature to generate LiCoO2. This is currently the most mature and widely used method in industrial production. When preparing lithium cobalt oxide using conventional methods such as solid-phase synthesis, sol-gel method, and co-precipitation method, the raw materials are usually first mixed, reacted, and sintered to obtain lithium cobalt oxide in bulk or larger particle products. Then, these products are crushed by equipment such as jaw crusher and ball mill to reduce the particle size. The crushed material then enters a multi-stage sorting process, where it is sorted according to the size, density, and other characteristics of the particles. Particles that do not meet the particle size requirements are screened out and returned to the crushing process for further crushing, while particles that meet the requirements are collected as the final product.
[0004] In the existing technology, the sorting device is equipped with multiple sets of screen plates for sorting operations. These multiple sets of screen plates need to be assembled and installed by means of brackets, springs and other components. Long-term vibration can easily lead to loosening of screen plate bolts, deformation of screen mesh, and even misalignment of screen plates, resulting in a decrease in particle size sorting accuracy and reducing the sorting effect of lithium cobalt oxide raw materials. Utility Model Content
[0005] Based on this, the purpose of this utility model is to provide a multi-stage sorting device for lithium cobalt oxide raw materials to solve the technical problems in the background art mentioned above.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-stage sorting device for lithium cobalt oxide raw materials, comprising a sorting device body, a sorting cylinder, and a feeding plate, wherein the sorting cylinder is movably installed inside the sorting device body, and the feeding plate is installed on the outer wall of the sorting cylinder;

The receiving seat is provided with multiple sets of support plates to assist in supporting the sorting cylinder, avoiding deformation of the sorting holes due to deformation of the sorting cylinder, thus improving the sorting effect of lithium cobalt oxide raw material. With the feeding plate continuously rotating, the lithium cobalt oxide raw material is in a continuous state of movement, and some lithium cobalt oxide raw material with a particle size smaller than the diameter of the sorting hole at the end of the feeding plate will fall back from the upper area of the feeding plate to the lower area of the feeding plate, further improving the sorting effect of lithium cobalt oxide raw material.

A toothed synchronous belt is provided between the limiting ring and the drive shaft.
[0015] Preferably, the drive shaft rotates, and a toothed synchronous belt connects the drive shaft and the limiting ring. Therefore, the limiting ring rotates, thereby driving the sorting cylinder to rotate.
[0016] The present invention is further configured such that the feeding plate is arranged in an inclined ring shape.
[0017] Preferably, when the feeding plate rotates, it is arranged in an inclined ring shape, thereby driving the lithium cobalt oxide raw material to move upward.
[0018] The present invention is further configured such that the sorting holes at the end of the sorting cylinder are all inclined, and the sorting holes at the end of the feeding plate are all vertical.
[0019] Preferably, the orientation of the sorting holes improves the efficiency of lithium cobalt oxide raw materials passing through the sorting holes.
[0020] The present invention is further configured such that the receiving seat is provided with a first collection bin, a second collection bin, a third collection bin and a fourth collection bin, and the fourth collection bin is connected to the discharge port at the upper end of the sorting cylinder.
[0021] Preferably, the lithium cobalt oxide raw material falls into the first, second, third and fourth collection bins respectively.
[0022] The present invention is further configured such that the diameter of the sorting hole in the upper region of the first collection bin is smaller than the diameter of the sorting hole in the upper region of the second collection bin.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0037] The embodiments of this utility model will be described below based on its overall structure.
[0038] A multi-stage sorting device for lithium cobalt oxide raw materials, such as Figure 1 - Figure 6 As shown, it includes a sorting device body 1, a sorting cylinder 3 and a feeding plate 4. The sorting cylinder 3 is movably installed inside the sorting device body 1, and the feeding plate 4 is installed on the outer wall of the sorting cylinder 3.
[0039] Both the sorting cylinder 3 and the feeding plate 4 have multiple sorting holes with different diameters. The bottom of the main body 1 of the sorting device is equipped with a receiving seat 6. Multiple sets of annular support plates are installed inside the receiving seat 6, and the multiple sets of support plates are movably connected to the inner wall of the sorting cylinder 3. The multiple sets of support plates provide auxiliary support for the sorting cylinder 3.
[0040] The upper end of the main body 1 of the sorting device is provided with a feed pipe 2. The lithium cobalt oxide raw material enters the interior of the main body 1 of the sorting device through the feed pipe 2. The bottom end of the receiving seat 6 is provided with multiple sets of discharge pipes 11. The lithium cobalt oxide raw material is discharged from the interior of the receiving seat 6 through multiple sets of discharge pipes 11.
[0041] Please see Figure 1 - Figure 2One end of the feed pipe 2 is connected to a conveying device, and one end of each of the multiple sets of discharge pipes 11 is connected to a collection box. The conveying device transports the lithium cobalt oxide raw material to one end of the feed pipe 2. The lithium cobalt oxide raw material enters the body 1 of the sorting device through the feed pipe 2. The lithium cobalt oxide raw material enters the multiple sets of discharge pipes 11. The multiple sets of discharge pipes 11 transport the sorted lithium cobalt oxide raw material to the multiple sets of collection boxes respectively.
[0042] Please see Figure 1 - Figure 3 A drive motor 12 is installed on one side of the main body 1 of the sorting device. A drive shaft 13 is installed at the output end of the drive motor 12. When the drive motor 12 is started, it drives the drive shaft 13 to rotate.
[0043] Please see Figure 2 - Figure 5 A limiting ring 5 is installed at the bottom of the sorting cylinder 3, and one end of the limiting ring 5 extends to the outer wall of the main body 1 of the sorting device. A toothed synchronous belt is provided between the limiting ring 5 and the drive shaft 13. The drive shaft 13 rotates, and the toothed synchronous belt is provided between the drive shaft 13 and the limiting ring 5, so the limiting ring 5 rotates, thereby driving the sorting cylinder 5 to rotate.
[0044] Please see Figure 3 - Figure 5 The feeding plate 4 is arranged in an inclined ring shape. When the feeding plate 4 rotates, it is arranged in an inclined ring shape, which drives the lithium cobalt oxide raw material to move upward. The inclined arrangement of the feeding plate 4 causes the lithium cobalt oxide raw material to move towards one end of the feeding plate 4, thereby lifting the lithium cobalt oxide raw material through the sorting hole at the end of the sorting cylinder 3.
[0045] Please see Figure 3 - Figure 5 The sorting holes at all three ends of the sorting cylinder are set at an angle, and the sorting holes at all four ends of the feeding plate are set vertically. The orientation of the sorting holes further improves the efficiency of lithium cobalt oxide raw materials passing through the sorting holes.
[0046] Please see Figure 4 - Figure 6 The receiving seat 6 is equipped with a first collection bin 7, a second collection bin 8, a third collection bin 9 and a fourth collection bin 10. The fourth collection bin 10 is connected to the discharge port at the upper end of the sorting cylinder 3. The lithium cobalt oxide raw material falls into the first collection bin 7, the second collection bin 8, the third collection bin 9 and the fourth collection bin 10 respectively.
[0047] Please see Figure 4 - Figure 6 The diameter of the sorting holes in the upper region of the first collection bin 7 is smaller than the diameter of the sorting holes in the upper region of the second collection bin 8, and the particle size of the lithium cobalt oxide raw material falling into the first collection bin 7 is smaller than the particle size of the lithium cobalt oxide raw material inside the second collection bin 8.
[0048] Please see Figure 4 - Figure 6 The diameter of the sorting holes in the upper region of the second collection bin 8 is smaller than the diameter of the sorting holes in the upper region of the third collection bin 9, and the particle size of the lithium cobalt oxide raw material falling into the second collection bin 8 is smaller than the particle size of the lithium cobalt oxide raw material inside the third collection bin 9.
[0049] The working principle of this utility model is as follows: When the staff uses the device to perform multi-stage sorting of lithium cobalt oxide raw materials, the feeding device transports the lithium cobalt oxide raw materials to one end of the feed pipe 2. The lithium cobalt oxide raw materials enter the body 1 of the sorting device through the feed pipe 2. Then the staff starts the drive motor 12, which drives the drive shaft 13 to rotate. The drive shaft 13 is connected to the limiting ring 5 by a toothed synchronous belt. Therefore, the limiting ring 5 rotates, thereby driving the sorting cylinder 5 to rotate, and then driving the feeding plate 4 to rotate.
[0050] When the feeding plate 4 rotates, the feeding plate 4 is set in an inclined ring shape, thereby driving the lithium cobalt oxide raw material to move upward. The feeding plate 4 and the sorting cylinder 3 are both opened with multiple sorting holes, so that the lithium cobalt oxide raw material falls into the receiving seat 6 through the multiple sorting holes respectively.
[0051] Because the diameter of the sorting holes in the upper region of the first collection bin 7 is smaller than that in the upper region of the second collection bin 8, the particle size of the lithium cobalt oxide raw material falling into the first collection bin 7 is smaller than that in the second collection bin 8. The diameter of the sorting holes in the upper region of the second collection bin 8 is smaller than that in the upper region of the third collection bin 9, so the particle size of the lithium cobalt oxide raw material falling into the second collection bin 8 is smaller than that in the third collection bin 9. The remaining lithium cobalt oxide raw material falls into the fourth collection bin 10. The bottom inner walls of the first collection bin 7, the second collection bin 8, the third collection bin 9, and the fourth collection bin 10 are inclined towards the multiple sets of discharge pipes 11. The lithium cobalt oxide raw material enters the multiple sets of discharge pipes 11, and the multiple sets of discharge pipes 11 transport the sorted lithium cobalt oxide raw material to the multiple sets of collection boxes.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
