Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing equipment, in particular to a plowshare mixing component. Background Art

[0002] Ternary materials combine the advantages of lithium cobalt oxide, lithium nickel oxide and lithium manganese oxide. They are new lithium battery positive electrode materials developed in recent years. They have excellent characteristics such as high capacity, low cost and good safety, and have become the most promising positive electrode materials to replace lithium cobalt oxide. Among them, the production process of ternary materials generally consists of batching, sintering, crushing, washing, packaging and other processes. Batching is to mix two or more raw materials evenly so that the mixture entering sintering can react evenly. Therefore, batching is one of the most important processes in the production process. The main shaft is driven to rotate by a driving device, so that the plow blade set on the main shaft mixes the ternary materials, thereby achieving the purpose of mixing. However, during the mixing process of the existing ternary material mixer, some of the plow blades are set in an arc shape on the side, and their structure is single, which has a poor effect on stirring and turning the materials, and makes the material movement and diffusion frequency low, thereby reducing the uniformity of material mixing.

However, the existing mixers used for ternary materials have a single plowshare structure during the mixing process, which has a poor effect on material stirring and flipping, resulting in a low frequency of material movement and diffusion, thereby reducing the uniformity of material mixing. Therefore, it is necessary for this application to provide a plowshare mixing component that has a good effect on material stirring and flipping and enhances the material movement and diffusion frequency.

[0017] The technical solution of the utility model is described clearly and completely below in conjunction with the specific embodiments of the utility model. The described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] like Figure 1-3 As shown, a plowshare mixing assembly provided by the utility model is used in a ternary material mixer, and the plowshare mixing assembly of the present application is used to mix the ternary materials. The plowshare mixing assembly includes a main shaft 1, and the main shaft 1 is rotatably arranged horizontally in the machine slot of the mixer, and one end of the rotating shaft is drivingly connected to the main motor configured on the outside of the mixer. A plurality of connecting rods are fixedly arranged on the main shaft 1. At least five connecting rods are fixedly arranged on the above-mentioned main shaft 1 of the present application. In order to realize that different plowshares 4 can drive materials to rotate within a circumferential range of different diameters, the connecting rods of the present application include a long-axis connecting rod 2 and a short-axis connecting rod 3 respectively located on the left and right sides of the main shaft 1, and the long-axis connecting rod 2 and the short-axis connecting rod 3 are arranged at equal intervals and staggered, and the spacing between the long-axis connecting rod 2 and the short-axis connecting rod 3 is 20-40cm, which increases the turning effect of the plowshare 4 on materials at different positions in the mixer and improves its mixing uniformity of the materials.

[0020] The ends of the long-axis connecting rod 2 and the short-axis connecting rod 3 are both provided with a plow 4. Figure 2-3As shown, the plow blade 4 is in the shape of a triangular prism, and the inclined surface of the plow blade 4 is respectively connected to the long-axis connecting rod 2 and the short-axis connecting rod 3. The rotation radius of the long-axis connecting rod 2 and the short-axis connecting rod 3 are different. Different plow blades 4 can realize the rotation of materials within the circumferential range of different diameters; the length of the inclined surface of the plow blade 4 is 15-20cm, and the edges and corners of the plow blade 4 are rounded corners or rounded edges after blunting, which increases the contact area between the plow blade 4 and the material, increases the amount of material driven by the plow blade 4 at a time, and combines the combined stirring of the long-axis connecting rod 2 and the short-axis connecting rod 3 to increase the turning effect of the plow blade 4 on the materials at different positions in the mixer, so that the diffusion frequency of the material movement is enhanced, thereby improving the uniformity of the plow blade mixing assembly of the present application on the mixing and stirring of the materials.

[0021] Example 2

[0022] On the basis of the above embodiment, in order to improve the stirring effect of the combination of the long axis connecting rod 2 and the short axis connecting rod 3, the present embodiment Figure 1 As shown, the blade direction of the plowshare 4 arranged on the long-axis connecting rod 2 and the short-axis connecting rod 3 on the left side of the main shaft 1 described in the present application is opposite to the blade direction of the plowshare 4 arranged on the long-axis connecting rod 2 and the short-axis connecting rod 3 on the right side of the main shaft 1, so that the plowshare 4 arranged on the long-axis connecting rod 2 and the short-axis connecting rod 3 can stir and mix the materials within the circumferential range of different diameters, thereby further improving the uniformity of the mixing. After comparison with the production test, compared with the stirring component of the mixer in the prior art, the plowshare mixing component provided by the present application improves the uniformity of mixing the ternary materials by more than 8% compared with the existing stirring component.

[0023] Example 3

[0024] On the basis of the above embodiment, in order to improve the stirring and mixing effect of the materials, the present embodiment Figure 1 As shown, the length of the long-axis connecting rod 2 described in the present application is greater than that of the short-axis connecting rod 3, and the length of the long-axis connecting rod 2 is 1.25-1.5 times the length of the short-axis connecting rod 3. After comparison in production tests, it is found that when the length of the long-axis connecting rod 2 in the present application is 1.25 times the length of the short-axis connecting rod 3, the material at the discharge end of the mixer is randomly checked, and it is detected that the material mixing uniformity is high, which meets the production requirements of the next process.

[0025] When the utility model is working, the material enters the machine slot through the feed port of the mixer, and the main motor drives the active rotation. The plow blades 4 on the main shaft 1 rotate to drive the material to make a circular motion in the machine slot, thereby increasing the contact area between the plow blade 4 and the material, and increasing the amount of material driven by the plow blade 4 at a single time. Combined with the combined stirring of the long-axis connecting rod 2 and the short-axis connecting rod 3, the turning effect of the plow blade 4 on the material at different positions in the mixer is increased, so that the material movement diffusion frequency is enhanced, thereby improving the uniformity of the plow blade mixing component of the present application on the material mixing and stirring. The mixer of the present application is also provided with a flying knife scattering component (not shown in the figure) corresponding to the plow blade mixing component. At the same time, the material flows along the flying knife scattering component and is scattered by the high-speed rotating flying knife, which is continuously replaced and compounded, so that the material is further mixed evenly in a shorter time; thereby effectively solving the problem that the plow blade 4 of the existing ternary material mixer has a single structure during the mixing process, has a poor stirring and turning effect on the material, and has a low material movement diffusion frequency, thereby reducing the uniformity of material mixing.
