Technical Field

[0001] The utility model relates to the technical field of sodium carbonate crushing, in particular to a sodium carbonate crushing device with a screening structure. Background Art

[0002] With the rapid development of the new energy industry, sodium-ion batteries, as a new battery category, are rapidly gaining industrialization due to their advantages in resource cost, energy density, high-temperature resistance, and cycle life. This has led to a corresponding increase in demand for cathode materials for sodium-ion batteries. Numerous types of cathode materials are used to synthesize sodium-ion batteries. Considering the cost, process safety, and acid-alkalinity requirements of large-scale industrial production, sodium carbonate is the optimal sodium source for the industrial production of sodium battery cathode materials.

[0003] Layered oxide cathode materials, the first industrialized cathode materials for sodium-ion batteries, require sodium carbonate pulverization during production to ensure material performance and safety. Common sodium carbonate pulverization equipment, when the sodium carbonate particles are not sufficiently refined in the pulverizer, results in some larger particles in the final product, which in turn affects overall product quality. Workers often need to screen those sodium carbonate particles that do not meet the standard particle size and return them to the pulverizer for secondary or multiple pulverization, reducing work efficiency and increasing workload.

[0004] Therefore, for the above-mentioned sodium carbonate crushing device, when the sodium carbonate particles are not sufficiently refined in the crusher, some larger particles will be present in the final product, thereby affecting the overall product quality, which urgently needs to be solved. Utility Model Content

[0007] Preferably, by setting up a beating component, the thrust generated by high-speed rotation is used to throw the material out and hit it on the concave and convex tooth plate, resulting in violent collision, friction, and shearing to achieve ultra-fine crushing of the particles. The starting motor three drives the rotating rod two to rotate, thereby driving the hitting block to rotate. The hitting block beats the material, and the material hits the concave and convex tooth plate, thereby crushing it. By cooperating with the particle motion component, the material moves upward in a clockwise spiral, and the rebound effect of the hitting block changes the direction of movement, which can accelerate the material to a linear speed of about one hundred and eighty meters per second. First, it collides with other particles to be crushed, and then collides with the concave and convex tooth plate. Then, in conjunction with the screening component, the crushed heavy sodium carbonate is screened out to obtain fine powder that meets the particle size requirements, and the material that does not meet the particle size requirements continues to be crushed in the device, thereby ensuring that the heavy sodium carbonate is processed into fine powder of the required particle size, thereby improving the quality of crushing.

[0011] Preferably, a mounting part is installed on the upper end surface of the mounting box, a screening mesh is installed on the upper end of the mounting part, and a mounting frame is fixedly provided on the upper end of the screening mesh. Fine powder that meets the standards moves through the screening mesh into the cavity between the screening mesh and the device body. When it is necessary to replace the screening mesh with a different specification or maintain the screening mesh, the top cover can be opened, and the mounting frame can be pulled to separate the mounting part from the mounting box, and the screening mesh can be taken out, which is convenient for replacement or maintenance, further improving the practicality of the device, and screening meshes of different specifications can screen out fine powders of different standards.

[0012] Preferably, a guide plate is fixedly provided on the lower end face of the device body, and a discharge port is fixedly provided on the lower end face of the guide plate.

[0014] Beneficial effects of the utility model:

[0015] 1. By setting up a beating component, the thrust generated by high-speed rotation is used to throw the material out and hit it on the concave and convex tooth plate, generating violent collision, friction and shearing to achieve ultra-fine crushing of the particles. The starting motor 3 drives the rotating rod 2 to rotate, thereby driving the striking block to rotate. The striking block beats the material, and the material hits the concave and convex tooth plate to perform the crushing work. By coordinating with the particle motion component, the material moves upward in a clockwise spiral, and the rebound effect of the striking block changes the direction of movement, which can accelerate the material to a linear speed of about 180 meters per second. First, it collides with other particles to be crushed, and then collides with the concave and convex tooth plate. Then, with the screening component, the crushed heavy sodium carbonate is screened out to obtain fine powder that meets the particle size requirements, and the material that does not meet the particle size requirements continues to be crushed in the device, thereby ensuring that the heavy sodium carbonate is processed into fine powder of the required particle size, thereby improving the quality of crushing;
