Description

Technical Field

[0001] The invention belongs to the technical field of drying equipment, and specifically relates to a lithium battery drying equipment based on additive manufacturing. Background Art

[0002] Lithium battery drying equipment based on additive manufacturing is mainly used in the drying process of lithium battery production. By optimizing the equipment design through additive manufacturing technology, this equipment can provide more efficient and uniform drying effects, and can improve adaptability and performance through customized design. Additive manufacturing technology can design more complex and optimized drying channels to ensure uniform distribution of airflow and heat, thereby achieving uniform drying of battery materials and avoiding moisture residue. Using additive manufacturing, the equipment structure can be customized according to specific production needs and material properties to improve drying efficiency and quality. Lithium battery drying equipment based on additive manufacturing can not only improve the drying effect, but also help to achieve higher production efficiency and material quality.

[0003] A Chinese patent with the announcement number CN117387325A discloses a lithium battery material drying device, including a drying box, a placement rack, a fan and a heater; the placement rack and the heater are both arranged in the drying box; the drying box is equipped with a first air duct and a first threading tube; the fan is installed on the top of the drying box. The lithium battery material drying device disclosed in the present invention heats the box body by the heater to increase the temperature of the drying box, and the fan is used to provide wind pressure to the drying box so that the inside of the drying box is kept in a positive pressure state. When the wet material is heated, the volatilized moisture is discharged to the outside through the first air duct. Since the drying box is in a sealed state, the heat radiated by the heater can be evenly diffused into the inside of the drying box through the fan, so that the wet material in the box can be heated in all directions to prevent uneven drying.

[0004] However, the current lithium battery drying equipment based on additive manufacturing still has certain limitations when drying lithium battery materials. It is not ideal in ensuring that the lithium battery materials are heated evenly, resulting in uneven heat distribution during the drying process. This uneven heating will affect the drying efficiency, thereby extending the time required for drying and may lead to a decrease in material performance.

[0005] To this end, the present invention provides a lithium battery drying device based on additive manufacturing. Summary of the invention

The hot air will flow back into the drying box through the discharge head, thereby achieving the purpose of drying the lithium battery raw materials by circulating the hot air.

[0015] Furthermore, the filtering component includes a mounting frame and a filter plate. The mounting frame is arranged inside the filtering box, and the filter plate is fixedly arranged inside the mounting frame.

After placing the lithium battery raw materials, the sealing door 2 is closed to form a closed space inside the drying box 1. Then the heating component works to generate heat, and thus the lithium battery raw materials inside the placement groove 11 can be heated and dried. At the same time, when the driving motor 5 works, it will drive the support rod 9 to rotate. The support rod 9 will rotate smoothly through the bearing 8.

[0049] Working principle: First, the components of the drying equipment are manufactured by 3D printing and then assembled into the drying box 1. A sensor is arranged inside the drying box 1 to monitor the temperature inside the drying box 1. When drying the raw materials for preparing lithium batteries, the placement groove 11 is moved by pulling the handle 12. After moving the placement groove 11 out of the annular frame 10, the lithium battery raw materials to be dried are placed inside the placement groove 11, and then the placement groove 11 is reset. After placing the lithium battery raw materials, the sealing door 2 is closed to form a sealed space inside the drying box 1. Controlling the heating rod 4 to work generates heat, which then heats the temperature inside the drying box 1, and thus the lithium battery materials can be heated. The controller 39 can control the driving motor 5 to work. When the driving motor 5 works, it drives the support rod 9 to rotate. When the support rod 9 rotates, it drives the annular frame 10 to rotate, and thus the lithium battery raw materials can be driven to rotate for drying. When the annular frame 10 rotates, it drives the lithium battery raw materials to rotate, so as to uniformly heat and dry the lithium battery raw materials. When the support rod 9 rotates, it drives the driving gear 20 to rotate. When the driving gear 20 rotates, it drives the driven wheel 37 to rotate. When the driven wheel 37 rotates, it drives the support shaft 36 to rotate. The rotation of the support shaft 36 drives the rotating shaft 29 to rotate through the cooperation of the driving wheel 38 and the pulley 31. When the rotating shaft 29 rotates, it drives the fan blade 30 to rotate, which then causes the air to flow. After the air flows into the filter box 22 through the air extraction head 23, the air flows through the filter plate 25. The filter plate 25 can filter and intercept the particulate matter carried by the air, thus achieving the purpose of purifying the air.
