Description

Technical Field

[0001] This utility model relates to the field of lithium battery drying technology, specifically to a lithium battery drying production drying device. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as positive / negative electrode materials and a non-aqueous electrolyte solution. The main purpose of drying in lithium-ion battery production is to remove moisture from the materials, thereby improving battery performance and lifespan. Dried lithium-ion battery materials can better exert their electrochemical performance, thus improving the overall performance of the battery and extending its lifespan. The moisture removed during the drying process can reduce internal corrosion and the risk of short circuits, thereby improving the battery's safety and reliability.

[0003] Currently, lithium batteries are dried in a drying chamber. Although the drying chamber can promote the flow of drying air through the fan, the ventilation inside the drying chamber is limited by the size and position of the air inlet and outlet. This results in a small space for air inlet and outlet and a large variation in the strength of the airflow. Consequently, the drying inside the drying chamber is uneven, slow, and impractical.

The other end of the telescopic pipe 5 is connected to the output end of a circulating fan 7 on one side of the drying chamber 1 via a connecting pipe 6. The lower end is provided with an air outlet 8. The input end of the circulating fan 7 is connected to the air outlet 8 through a connecting pipe 6 to realize the drying circulation air supply inside the drying chamber 1. The filter screen 45, dehumidification plate 44 and electric heating wire 46 inside the air inlet box 41 have the functions of filtration, dehumidification and heating, so that the lithium battery is dried faster in the drying chamber 1. The diverter plate 22, the first air guide plate 23 and the second air guide plate 24 inside the air supply box 2 realize the air supply and guide, increase the uniformity of the air supply inside the drying chamber 1, and the air supply space is large and gentle, so the drying inside the drying chamber 1 is uniform. The hydraulic cylinder 3 set on the drying chamber 1 realizes the height adjustment of the air supply box 2 inside the drying chamber 1 under the action of the hydraulic cylinder 3, so as to meet the effective air supply and drying of lithium batteries of different heights inside the drying chamber 1.

[0023] Specifically, the air intake mechanism 4 includes an air intake box 41, a top cover 42, an air inlet 43, a dehumidifying plate 44, a filter screen 45, and an electric heating wire 46.
