Description

Technical Field

[0001] This utility model relates to the field of lithium carbonate processing structure technology, specifically to a complete system for lithium carbonate airflow pulverization, demagnetization, and packaging. Background Technology

[0002] Lithium carbonate, as an important lithium salt product, plays a crucial role in modern industry, especially in the new energy battery sector. With the rapid development of the new energy vehicle industry, the demand for high-purity, uniformly sized lithium carbonate continues to rise. In the production process of lithium carbonate, air jet milling, demagnetization, and packaging are critical steps. Traditional air jet milling equipment often struggles to precisely control particle size distribution when pulverizing lithium carbonate, resulting in inconsistent product quality. On the one hand, excessively coarse particles can affect the battery's charge-discharge performance and reduce its energy density; on the other hand, excessively fine particles may cause agglomeration, which is also detrimental to subsequent processing and applications.

[0003] Magnetic impurities in lithium carbonate can severely affect its performance in batteries and other products. However, existing demagnetization devices have low efficiency and cannot meet increasingly stringent product quality standards. Moreover, the demagnetization process may cause secondary contamination of the lithium carbonate itself, further impacting product quality. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a complete system for lithium carbonate airflow pulverization, demagnetization and packaging, which can effectively solve the problems in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a complete system for lithium carbonate airflow pulverization, demagnetization, and packaging, including a gas storage tank. A mounting frame is provided on one side of the gas storage tank. A storage hopper, a feeding frame, an iron separator, and a discharge port are fixed inside the mounting frame. The bottom end of the storage hopper is connected to the feeding frame. Inside the storage hopper are a feeding hopper, a feeding pipe connected to the bottom of the feeding hopper, and a grinding frame located on one side of the feeding pipe. A grinding nozzle is provided on one side of the grinding frame, and the other end of the grinding nozzle is located inside the feeding pipe. The bottom end of the feeding pipe is connected to the top end of the iron separator. The bottom end of the iron separator is connected to the discharge port, and the bottom end of the discharge port is connected to a hopper. The hopper is placed on top of a platform scale, and the platform scale is placed at the bottom of the mounting frame.

[0007] Furthermore, one end of the feed pipe is connected to the air pipe, and one end of the air tank is connected to both the air pipe and the compressed air pipe.

[0008] Furthermore, the iron remover includes a hollow frame, an iron removal rod disposed within the frame, and a positioning plate fixed to the iron removal rod. The upper and lower ends of the frame are respectively connected and fixed to the feeding frame and the discharge port.

[0009] Furthermore, the hopper is funnel-shaped, and the discharge pipe is a spiral-shaped hollow pipe.

[0010] Furthermore, multiple sets of grinding nozzles are arranged in an equidistant array on the grinding frame, and the grinding nozzles are kept in communication with the inner cavity of the grinding frame.

[0011] Furthermore, multiple sets of the iron removal rods are fixed at equal intervals on the positioning plate.

[0012] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0013] This invention utilizes a combined structure of a storage silo and a feeding frame, with a hopper structure within the storage silo. Material is collected and temporarily stored along this structure, then poured into a feeding pipe via an air pipe on one side. Compressed air and material simultaneously enter the feeding pipe, where the material undergoes initial collision and crushing. As it passes through the grinding frame, multiple grinding nozzles further accelerate the collision and push the material downwards, increasing the collision speed and crushing effect. The material then enters the bottom iron remover, where magnetic materials such as iron filings are adsorbed by the iron removal rod. Other materials are collected in a bottom hopper through the discharge hopper and weighed on a platform scale. This integrated process of crushing, demagnetizing, and packaging lithium carbonate further enhances the screening effect by reprocessing the materials in the hopper. Attached Figure Description

[0022] The top end of the feeding pipe 33 is connected to the air pipe 32, and one end of the air storage tank 1 is connected to both the air pipe 32 and the compressed air pipe 42. Through the combined structure of the storage bin 3 and the feeding frame 5, and the feeding hopper 31 structure provided in the storage bin 3, the material is collected and temporarily stored along the flat surface, and then poured into the feeding pipe 33 through the air pipe 32 on one side. Compressed air and material enter the feeding pipe 33 at the same time, and the material undergoes preliminary collision and crushing. When passing through the grinding frame 4, the material can be further accelerated and pushed downward through the structure of multiple grinding nozzles 41, thereby increasing the collision speed and the effect of collision and crushing.
