Technical Field

[0001] This utility model belongs to the field of lithium manganese oxide product processing technology, specifically a lithium manganese oxide product pretreatment device with grading and screening function. Background Technology

[0002] Lithium manganese oxide is an important component of the cathode material in lithium-ion batteries, and the particle size distribution of its raw materials has a significant impact on the electrochemical performance of the final product. Therefore, efficient and precise classification and screening pretreatment of lithium manganese oxide products is a crucial step in the production process.

[0003] Currently, the screening equipment commonly used in the industry is mostly ultrasonic vibrating screens or rotary vibrating screens. These screens use ultrasonic generators and vibrating motors to generate excitation force, causing the material on the screen to move, thereby achieving the separation of particles of different sizes. However, existing screening devices still have several obvious drawbacks in practical applications: First, the material tends to concentrate in a localized area of ​​the screen during feeding, leading to accumulation, which not only reduces screening efficiency but also affects screening accuracy and continuity; second, traditional screen installation methods are mostly bolt fixing or integral welding, making screen replacement or cleaning cumbersome, time-consuming, and labor-intensive, and unable to meet the need for flexible adjustment of screening specifications. To solve the above problems, a pretreatment device for lithium manganese oxide products with grading screening function is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a lithium manganese oxide product pretreatment device with grading and screening function in order to solve the above-mentioned problems.

[0006] The screening box has multiple strip-shaped holes on one side wall from top to bottom. The screening mesh can be fitted through the strip-shaped holes. Two opposite inner walls have multiple inclined slots from top to bottom. The left and right sides of the screening mesh are fitted into the slots. Locking plates are fixedly connected to the two corners of the exposed side of the screening mesh. The locking plates have U-shaped grooves. Screws are rotatably mounted on the screening box on both sides of the strip-shaped holes. The screw housings are rotatably engaged in the U-shaped grooves. Nuts are threaded onto the screws.

[0007] In a preferred embodiment, a feeding hopper is fixedly connected to the bottom of the screening box.

[0008] In a preferred embodiment, a bottom discharge port is provided on one side of the lower part of the screening box, and a discharge nozzle is fixedly installed on the screening box at the bottom discharge port.

[0009] In a preferred embodiment, the bottom of the inner cavity of the screening box is designed to be inclined, and the bottom discharge port is located at the lowest point of the inclined surface at the bottom of the inner cavity of the screening box.

[0010] In a preferred embodiment, a plurality of discharge ports corresponding to the screening screen are provided on one side wall of the screening box, and each discharge port is provided with a discharge nozzle fixedly installed on the screening box.

[0011] In a preferred embodiment, the protrusions in adjacent rows are staggered.

A screening box 5 for lithium manganese oxide products is fixedly mounted on the mounting plate 3. The inner cavity of the screening box 5 is provided with multiple inclined screening screens 6 from top to bottom. In this structure, the vibration motor 4 drives the screening box 5 on the mounting plate 3 to vibrate, and then the vibrating screening screens 6 are used to perform grading and screening pretreatment of the lithium manganese oxide products.

[0025] refer to Figures 1 to 4 As shown, a feeding hopper 15 is fixedly connected to the bottom of the screening box 5. In this structure, the lithium manganese oxide product is fed into the screening box 5 using the feeding hopper 15.

[0026] refer to Figures 1 to 4 As shown, a bottom discharge port 16 is provided on one side of the lower part of the screening box 5. A discharge nozzle 17 is fixedly installed on the screening box 5 at the bottom discharge port 16. The bottom of the inner cavity of the screening box 5 is designed to be inclined. The bottom discharge port 16 is located at the lowest point of the inclined surface at the bottom of the inner cavity of the screening box 5. In this structure, the bottom discharge port 16 and the discharge nozzle 17 are used to discharge the lithium manganese oxide product at the bottom of the screening box 5.

[0027] refer to Figures 1 to 4As shown, a plurality of discharge ports 18 corresponding to the screening screen 6 are provided on one side wall of the screening box 5. The discharge ports 18 are equipped with discharge nozzles 19 fixedly installed on the screening box 5. In this structure, the lithium manganese oxide product screened by the screening screen 6 is discharged out of the screening box 5 through the discharge ports 18 and the discharge nozzles 19.

[0028] refer to Figures 1 to 4 As shown, an inclined distribution plate 7 is fixedly installed at the top of the inner cavity of the screening box 5. Multiple rows of protrusions 8 are fixedly connected to the distribution plate 7. The protrusions 8 of adjacent rows are staggered. In this structure, when lithium manganese oxide products are put into the screening box 5, they will first fall onto the distribution plate 7. Then, with the vibration of the screening box 5, the lithium manganese oxide products will slide down along the distribution plate 7. At this time, the protrusions 8 can separate the accumulated lithium manganese oxide products, so that they will eventually fall evenly onto the top screening screen 6, thereby avoiding product accumulation and affecting screening efficiency.

[0029] refer to Figures 1 to 4 As shown, one side wall of the screening box 5 has multiple strip-shaped holes 9 from top to bottom. The screening mesh 6 can be fitted through the strip-shaped holes 9. The two opposite inner walls of the screening box 5 have multiple opposite and inclined slots 10 from top to bottom.

The locking plates 11 have U-shaped grooves 12. The two sides of the strip-shaped holes 9 are provided with screws 13 that are rotatably installed on the screening box 5. The screws 13 are rotatably engaged in the U-shaped grooves 12. Nuts 14 are threaded onto the screws 13. In this structure, when it is necessary to disassemble the screening mesh 6, the personnel only need to unscrew the nuts 14, then rotate the screws 13 and disengage them from the U-shaped grooves 12 of the locking plates 11. Then the personnel can pull the screening mesh 6 out of the screening box 5, thereby achieving quick disassembly of the screening mesh 6 and allowing the screening mesh 6 to be replaced as needed.

[0030] refer to Figures 1 to 4 As shown, a handle 20 is fixedly connected to the exposed side of the screening screen 6. In this structure, the handle 20 is used to facilitate pulling the screening screen 6 outward.

[0031] The implementation principle of a lithium manganese oxide product pretreatment device with grading and screening function according to an embodiment of this application is as follows: In use, lithium manganese oxide products are fed into the screening box 5 using the feeding hopper 15. The lithium manganese oxide products will first fall onto the distribution plate 7. Then, with the vibration of the screening box 5, the lithium manganese oxide products will slide down along the distribution plate 7. At this time, the accumulated lithium manganese oxide products can be separated by the protrusions 8, so that they finally fall evenly onto the uppermost screening screen 6. Then, the vibrating screening screen 6 is used to perform grading and screening pretreatment on the lithium manganese oxide products. The lithium manganese oxide products screened by the screening screen 6 are discharged from the screening box 5 using the discharge port 18 and the discharge nozzle 19. The lithium manganese oxide products at the bottom of the screening box 5 are discharged from the screening box 5 using the bottom discharge port 16 and the discharge nozzle 17.

[0032] When it is necessary to disassemble the screening screen 6, the operator only needs to unscrew the nut 14, then rotate the screw 13 and disengage it from the U-shaped groove 12 of the locking plate 11. The operator can then pull the screening screen 6 out of the screening box 5, thereby achieving quick disassembly of the screening screen 6. The screen 6 can then be reinstalled by reversing the operation.
