Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for lithium battery slurry mixers, and particularly relates to a dispersion disc for lithium battery slurry. Background Art

[0002] In the mixing process of lithium battery raw materials, it is necessary to mix and stir the lithium battery raw materials and disperse and shear the slurry so that the lithium battery raw material particles are refined and evenly distributed. The dispersion discs in existing mixers mainly disperse and shear the lithium battery slurry through the shear teeth evenly distributed around the dispersion disc. The process time during the mixing process is between 6 and 10 hours, the mixing and dispersion time is relatively long, the efficiency is low, the floor area of the mixer is relatively large, and the dispersion effect is not good. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a dispersion disc for lithium battery slurry to solve the problems of long mixing and dispersion time, low efficiency, large floor area of the mixing equipment, and poor dispersion effect in the prior art.

[0004] To achieve the above object, the technical solution of the utility model is: a dispersion disc for lithium battery slurry, comprising a dispersion ring and a conical seat. A fixing plate is fixedly connected between the dispersion ring and the conical seat. A diversion groove is formed between two adjacent fixing plates. The bottom of the conical seat is fixedly connected to the output shaft of an external motor. One end of the fixing plate away from the conical seat is fixedly connected with a fixing column, and a small dispersion disc is rotatably connected to the fixing column.

[0005] Preferably, a rotating column is rotatably connected inside the fixing column. The end of the rotating column is fixedly connected with a small dispersion disc, and a limiting plate is fixedly connected to the bottom of the rotating column.

[0006] Preferably, the small dispersion disc is of a serrated structure.

[0007] Preferably, dispersion through holes are equidistantly arranged on the dispersion ring.

[0008] Preferably, a number of shear racks are equidistantly fixedly connected to the outer wall of the conical seat.

[0009] Preferably, dispersion hoppers are equidistantly fixedly connected to the outer wall of the dispersion ring.

[0010] Preferably, the dispersion hopper is in the shape of a quadrangular pyramid and is a hollow structure.

[0011] The advantages of the utility model are as follows:

[0012] 1. The dispersion ring is fixedly connected to the conical seat through a fixing plate. When the dispersion disk rotates at a high speed, a vortex flow is formed during the stirring process. In cooperation with the shear racks on its outer wall, the dispersion efficiency of the lithium battery raw materials is improved, and the dispersion effect is enhanced. The sheared slurry is guided through the dispersion through-holes on the dispersion ring, which increases the flow rate of the slurry, thereby improving the dispersion efficiency.

[0013] 2. Based on the eddy current formed in the conical seat, in cooperation with the small dispersion disk fixed at the end of the fixing plate, during the rotation of the slurry eddy current, the small dispersion disk is driven to rotate on the top of the fixed column, further improving the dispersion effect of the lithium battery raw materials.

[0014] 3. Under the combined action of the dispersion ring and the small dispersion disk, multiple dispersion disks are arranged at the bottom of the mixer. The multiple dispersion disks cooperate with each other, greatly shortening the stirring and dispersion time, improving the efficiency, enhancing the dispersion effect of the slurry. At the same time, the dispersion disks are small in volume and can be installed in a small mixer, reducing the floor area of the mixing equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present invention will be further described below in conjunction with the drawings and the detailed description of the embodiments.

[0020] As Figures 1 to 3 shown, a dispersion disk for lithium battery slurry includes a dispersion ring 1 and a conical seat 2. A fixing plate 3 is fixedly connected between the dispersion ring 1 and the conical seat 2. A diversion groove 4 is formed between two adjacent fixing plates 3. The bottom of the conical seat 2 is fixedly connected to the output shaft of an external motor. One end of the fixing plate 3 far from the conical seat 2 is fixedly connected to a fixed column 5, and a small dispersion disk 6 is rotatably connected to the fixed column 5.

[0021] To enable the small dispersion disk 6 to rotate better, a rotating column 7 is rotatably connected inside the fixed column 5. The end of the rotating column 7 is fixedly connected to the small dispersion disk 6, and the bottom of the rotating column 7 is fixedly connected to a limiting plate 8. When the dispersion ring 1 and the conical seat 2 cooperate to form a swirling flow, the small dispersion disk 6 rotates with the swirling flow, and the limiting plate 8 plays a role in limiting the rotation of the rotating column 7.

[0022] To further improve the shearing effect of the small dispersion disk 6 on the slurry, the small dispersion disk 6 is provided with a serrated structure.

[0023] To facilitate the dispersion and diversion of the lithium battery slurry, dispersion through-holes 9 are equidistantly arranged on the dispersion ring 1. The high-speed rotation of the conical seat 2 causes the slurry to form a swirling flow, and the sheared slurry flows out of the dispersion ring 1 through the dispersion through-holes 9.

[0024] To further improve the dispersion effect of the lithium battery slurry, a number of shear racks 10 are fixedly connected equidistantly on the outer wall of the conical seat 2. The multi-layer shear racks 10 cooperate to shear the lithium battery slurry, making the raw material particles of the lithium battery finer and more uniform.

[0025] To improve the dispersion effect outside the dispersion ring 1, dispersion hoppers 11 are fixedly connected equidistantly on the outer wall of the dispersion ring 1, and the shape of the dispersion hoppers 11 is a quadrangular pyramid. The dispersion hoppers 11 are of a hollow structure.

[0026] The working process of the present utility model is as follows: At least two dispersion disks of the present utility model are installed at the bottom of the lithium battery slurry stirring tank, and an external motor is used to provide driving force for the rotation of the dispersion disks. The lithium battery slurry is poured into the stirring tank, and the external motor is started. Driven by the motor, the conical seat 2 rotates at a high speed and drives the dispersion ring 1 fixedly connected through the fixing plate 3 to rotate. Under the high-speed rotation, the conical seat 2 causes the lithium battery slurry to form a swirling flow. The shear racks 10 on the outer wall of the conical seat 2 shear the lithium battery slurry. The lithium battery slurry in the swirling flow is diverted into the stirring tank through the dispersion through-holes 9 on the dispersion ring 1. At the same time, the small dispersion disk 6 also rotates under the action of the swirling flow, further shearing the lithium battery slurry to improve the dispersion effect. The dispersion hoppers 11 on the outer wall of the dispersion ring 1 can also play a role in dispersing and shearing the lithium battery slurry, and at the same time further improve the dispersion efficiency of the lithium battery slurry. Through the cooperation of the dispersion disk of the present utility model and the stirring tank, the floor area occupied by the stirring equipment is reduced, the stirring and dispersion time is shortened, and the stirring and dispersion efficiency and effect are improved.

[0027] The above are only the preferred examples of the present utility model. The technical solutions of the present utility model are not limited thereto. It should be pointed out that for those of ordinary skill in the art, under the technical inspiration provided by the present utility model, as common general knowledge in the art, other equivalent deformations and improvements can also be made, which should also be regarded as the protection scope of the present utility model.
