Description

Technical Field

[0001] This utility model relates to the field of processing technology for single-crystal high-nickel ternary cathode materials, and specifically to a crushing device for single-crystal high-nickel ternary cathode materials. Background Technology

[0002] Ternary high-nickel cathode material is a high-performance cathode material used in lithium-ion batteries. It is mainly composed of oxides of three elements: nickel, cobalt, and manganese, with nickel having a relatively high content. In the processing of ternary high-nickel cathode material, the raw materials are usually crushed into particles and then produced by chemical reaction.

[0003] In the prior art, patent document CN221693747U discloses a lithium-ion battery cathode material lithium manganese oxide pulverizing device, including a pulverizing barrel, a primary pulverizing mechanism, and a secondary pulverizing mechanism. The pulverizing barrel has a protective cover at its upper end and a screen inside its bottom end. The primary pulverizing mechanism includes a feeding hopper, a first pulverizing roller, a second pulverizing roller, and pulverizing blades. The feeding hopper is fixedly connected to the feeding port at the upper end of the pulverizing barrel. Two symmetrical first pulverizing rollers are rotatably connected to the upper inner wall of the feeding hopper, and two symmetrical second pulverizing rollers are rotatably connected to the lower inner wall of the feeding hopper. Pulverizing blades are uniformly distributed on the outer surface of the second pulverizing roller. The secondary pulverizing mechanism is located at the upper end of the pulverizing barrel. This lithium-ion battery cathode material lithium manganese oxide pulverizing device has a compact structure, requires little floor space, saves space, and provides a continuous pulverizing process. Different pulverizing methods are used in combination to improve work efficiency.

[0004] To address the issue that existing crushing devices require a motor to drive the crushing shaft to crush raw materials, the current technology uses a preliminary crushing mechanism to grind and crush the raw materials. However, this method still suffers from low crushing efficiency and requires repeated grinding, making continuous operation impossible and thus reducing the practicality of the crushing device.

[0027] The present invention will be further described in detail below with reference to embodiments: Example

[0028] like Figure 1-5 As shown, this utility model provides a crushing device for single-crystal high-nickel ternary cathode materials, including a support base 1; a collection assembly 2 disposed on the outer surface of the support base 1 for discharging material; a crushing unit 3 disposed on the outer surface of the support base 1 for crushing; and a scraping unit 4 disposed inside the collection assembly 2 for cleaning. The crushing unit 3 includes a driving assembly disposed on the outer surface of the support base 1 and an adjusting assembly disposed inside the collection assembly 2. The scraping unit 4 includes a telescopic assembly disposed on the outer surface of the collection assembly 2 and a cleaning assembly disposed on the outer surface of the telescopic assembly. The driving assembly includes a housing 21, the bottom surface of which is fixedly connected to the upper surface of the support base 1. A collection tank 22 is fixedly connected to the outer surface of the device. A drive motor 23 is detachably connected to one side of the collection tank 22. A screw feeder 24 is fixedly connected to the drive end of the drive motor 23 and rotates with the inner wall of the collection tank 22. When using the crushing device for single crystal high-nickel ternary cathode material, the raw material is first put into the inside of the shell 21. The baffle is used to make it gather in the middle of the shell 21. Finally, the crushing unit 3 crushes the raw material. The crushed raw material will enter the collection tank 22 from the bottom of the shell 21. Finally, the drive motor 23 is started to drive the screw feeder 24 to rotate, so that the processed raw material can be discharged easily. Example

[0029] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the driving assembly includes a mounting platform 31 fixedly connected to the upper surface of the support base 1. A fixing plate 35 is detachably connected to the outer surface of the mounting platform 31. A limiting slide rod 36 is detachably connected to one side of the fixing plate 35. A moving plate 34 is slidably connected to the outer surface of the limiting slide rod 36. A drive motor 32 is detachably connected to the upper surface of the moving plate 34. A reducer 33 is rotatably connected to the driving end of the drive motor 32 and detachably connected to the upper surface of the moving plate 34. A crushing and grinding roller 37 is rotatably connected to the driving end of the reducer 33. The adjusting assembly includes a moving block 38. A limiting rod detachably connected to the inner wall of the housing 21 is slidably connected to the inner wall of the moving block 38. The inner wall of the moving block 38 is connected to the crushing and grinding roller. The two ends of 37 are rotatably connected. One side of the moving block 38 is fixedly connected to a limiting spring 39 that is fixedly connected to the inner wall of the housing 21. One side of the moving block 38 is fixedly connected to a hydraulic cylinder 310 that is detachably connected to the outer surface of the housing 21. Before the raw material is put into the inside of the housing 21, the moving block 38 is moved by starting the hydraulic cylinder 310 under the action of the limiting spring 39 and the limiting rod, thereby adjusting the position of the crushing roller 37 inside the housing 21. During the adjustment process, the reducer 33, the second drive motor 32 and the moving plate 34 will move synchronously under the limit of the limiting slide rod 36, thereby adjusting the particle size of the crushed raw material. After the adjustment is completed, the second drive motor 32 can be started, and the crushing roller 37 can be driven to rotate in conjunction with the reducer 33 to crush the raw material. Example

[0030] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the telescopic component includes a telescopic limiting rod 41 and a hydraulic cylinder 42. One side of the telescopic limiting rod 41 and the hydraulic cylinder 42 are detachably connected to the outer surface of the housing 21. The cleaning component includes a mounting plate 43. One side of the mounting plate 43 is detachably connected to the telescopic end of the telescopic limiting rod 41 and the hydraulic cylinder 42. A scraper 44 is fixedly connected to the outer surface of the mounting plate 43. During the crushing and grinding process of the crushing roller 37, the hydraulic cylinder 42 is activated in conjunction with the telescopic limiting rod 41 to drive the mounting plate 43 to move, thereby causing the scraper 44 to adhere to the outer surface of the crushing and grinding roller 37 and clean the outer surface of the crushing and grinding roller 37.

[0031] The working principle of the pulverizing device used for single-crystal high-nickel ternary cathode materials will be explained in detail below.

[0032] like Figure 1-5As shown, when using the crushing device for single-crystal high-nickel ternary cathode material, the raw material is first fed into the interior of the housing 21. The baffles allow it to gather in the middle of the housing 21. Finally, the crushing unit 3 crushes the raw material. Before the raw material is fed into the housing 21, the hydraulic cylinder 310 is activated, causing the moving block 38 to move under the action of the limiting spring 39 and the limiting rod, thereby adjusting the position of the crushing roller 37 inside the housing 21. During the adjustment process, the reducer 33, the drive motor 32, and the moving plate 34 move synchronously under the limit of the limiting slide rod 36, thus adjusting the crushing position of the raw material. After the particle size is adjusted, the crushing roller 37 can be driven to rotate by starting the second drive motor 32 and the reducer 33 to crush the raw material. During the crushing process of the crushing roller 37, the mounting plate 43 is moved by starting the second hydraulic cylinder 42 and the telescopic limit rod 41, so that the scraper 44 is attached to the outer surface of the crushing roller 37 to clean the outer surface of the crushing roller 37. The crushed raw material will enter the collection tank 22 from the bottom of the shell 21. Finally, the first drive motor 23 is started to drive the screw feeder 24 to rotate, so that the processed raw material can be discharged easily.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
