Detailed implementation manners

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] The performance of the non-metallic material dispersant is usually affected by its particle size. Through the purification and screening device, the particle size distribution of the dispersant can be controlled to ensure that the particle size of the dispersant used is within an appropriate range, which is crucial for the uniformity and performance stability of the electrode material. However, the existing screening devices are usually designed with a single-layer sieve mesh or a single sieve hole size, and each screening can only process materials of one particle size. Therefore, the functions of coarse screening and fine screening cannot be achieved simultaneously, and the screening level is relatively single.

[0022] To solve the defects existing in the above screening device during the screening process, please refer to Figures 1-5, a purification and screening device for preparing a dispersant for non-metallic materials of lithium batteries provided by the utility model can simultaneously achieve coarse screening and fine screening of materials. The coarse screening frame 51 can quickly remove larger particles, and the fine screening frame 52 can further refine the particle size. Multi-level screening can improve the overall screening efficiency. The purification and screening device is based on a base 1. A support plate 2 is rotatably installed on the top of the base 1. A screening member 5 is installed on the top of the support plate 2 through four elastic telescopic rods 4. The screening member 5 includes a coarse screening frame 51, a fine screening frame 52, and a receiving frame 53 arranged in sequence from top to bottom. A first connecting rod 55 is installed between the coarse screening frame 51 and the fine screening frame 52, and a second connecting rod 56 is installed between the fine screening frame 52 and the receiving frame 53. Doors 54 are installed on the outsides of the coarse screening frame 51, the fine screening frame 52, and the receiving frame 53. The coarse screening frame 51 is used for quickly screening large-particle materials, the fine screening frame 52 is used for further refining the particle size, and the receiving frame 53 is used for loading the finally screened small particles. The materials can be screened into three different levels of large, medium, and small particles. The four elastic telescopic rods 4 are evenly distributed, and the ends of the elastic telescopic rods 4 are fixedly connected to the bottom of the receiving frame 53. The vibration of the coarse screening frame 51, the fine screening frame 52, and the receiving frame 53 can be driven by the expansion and contraction of the elastic telescopic rods 4. A rotating shaft 6 is rotatably installed at the center position on the top of the support plate 2. The upper end of the rotating shaft 6 sequentially passes through the receiving frame 53, the fine screening frame 52, and the coarse screening frame 51 and extends to the outside of the coarse screening frame 51. Two pushing plates 14 are fixedly sleeved on the outer surface of the rotating shaft 6. The two pushing plates 14 are respectively arranged inside the coarse screening frame 51 and the fine screening frame 52. The rotation of the rotating shaft 6 can drive the two pushing plates 14 to rotate, and the rotation of the pushing plates 14 can flatten the materials in the coarse screening frame 51 and the receiving frame 53, avoiding material accumulation and improving the screening efficiency.

[0023] To ensure the screening effect of the coarse screening frame 51 and the fine screening frame 52, it is necessary to drive the coarse screening frame 51 and the fine screening frame 52 to vibrate. A first bevel gear 7 is fixedly sleeved on the lower end of the rotating shaft 6. Rotating rods 8 are rotatably installed on both sides of the top of the support plate 2. A second bevel gear 9 is fixedly connected to the end of the rotating rod 8. The second bevel gear 9 meshes with the first bevel gear 7. A cam 10 is fixedly sleeved on the outside of the rotating rod 8. The upper end of the cam 10 abuts against the bottom of the coarse screening frame 51. When the rotating shaft 6 rotates, it can drive the first bevel gear 7 to rotate. The rotation of the first bevel gear 7 can drive the rotating rod 8 to rotate through the second bevel gear 9, and then drive the cam 10 to rotate. The rotation of the cam 10 jacks up the receiving frame 53. When the receiving frame 53 is jacked to the highest position, the two pushing plates 14 can respectively contact the coarse screening frame 51 and the fine screening frame 52. The pushing plates 14 will not affect the upward movement of the coarse screening frame 51 and the fine screening frame 52. At this time, the elastic telescopic rod 4 deforms. When the cam 10 continues to rotate, the receiving frame 53 can fall due to its own gravity and the elastic force of the elastic telescopic rod 4. As the cam 10 rotates continuously, the receiving frame 53 can be intermittently jacked up. Cooperating with the elastic telescopic rod 4 can realize the up and down vibration of the coarse screening frame 51 and the fine screening frame 52. Thus, when the rotating shaft 6 rotates, it can not only drive the pushing plates 14 to rotate to level the materials in the coarse screening frame 51 and the fine screening frame 52, but also drive the coarse screening frame 51 and the fine screening frame 52 to vibrate, and fully screen the materials.

[0024] Since the rotation of the rotating shaft 6 requires a driving member, a servo motor 11 is fixedly installed on one side of the top of the support plate 2. The output end of the servo motor 11 is fixedly connected to a first belt pulley 12. A second belt pulley 3 is fixedly sleeved on the lower end of the rotating shaft 6. The second belt pulley 3 is arranged below the first bevel gear 7. The second belt pulley 3 and the first belt pulley 12 are both rotatably installed on the support plate 2. A synchronous belt 13 is commonly installed on the outside of the second belt pulley 3 and the first belt pulley 12. Driving the servo motor 11 to drive the first belt pulley 12 to rotate. The first belt pulley 12 drives the second belt pulley 3 to rotate through the synchronous belt 13. The rotation of the second belt pulley 3 can drive the rotating shaft 6 to rotate, and then the screening work of the materials can be realized.

[0025] After the screening is completed, the three different specifications of materials will respectively stay in the coarse screening frame 51, the fine screening frame 52 and the receiving frame 53. To facilitate the discharging of the three materials, refer to Figure 2As shown, a hydraulic rod 15 is fixedly installed at the center position of the top of the base 1. The output end of the hydraulic rod 15 is movably installed at the bottom of the support plate 2. A hinge seat is slidably installed at the bottom of the support plate 2. The output end of the hydraulic rod 15 is rotatably installed in the hinge seat. Support columns 16 are fixedly installed on both sides of the bottom of the support plate 2. The support columns 16 can provide auxiliary support force for the support plate 2. Driving the hydraulic rod 15 can lift the support plate 2, causing the support plate 2 to turn upward. The turning of the support plate 2 drives the coarse sieve frame 51, the fine sieve frame 52 and the receiving frame 53 to tilt. The door panel 54 can be automatically opened by its own gravity. The materials in the coarse sieve frame 51, the fine sieve frame 52 and the receiving frame 53 can fall freely. Workers can separately collect the materials through an external collection box.

The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices. Therefore, the control mode and the circuit connection of the present utility model will not be explained in detail.
