High-efficiency drying device for lithium battery production

Abstract

The invention relates to the technical field of lithium batteries, and discloses a high-efficiency drying device for lithium battery production. The high-efficiency drying device comprises a case body, a hot air blower is fixedly connected to the right side of the case body, and an air inlet pipe is fixedly connected to the left side of the hot air blower; four diversion pipes are fixedly connected to the back face of the air inlet pipe, the back faces of the four diversion pipes are each rotationally connected with a rotating frame, the back faces of the four rotating frames are each fixedlyconnected with a rotating shaft, and the four rotating shafts are each sleeved with a big gear; and four material guiding pipes are arranged at the top of the case body, the bottoms of the four material guiding pipes are each fixedly connected with a fixing barrel, and the four rotating frames are each internally provided with a ventilating duct. Hot air is fed into the air inlet pipe through thehot air blower and then enters the ventilating ducts through the diversion pipes for drying lithium batteries in charging grooves, and the moisture generated by the lithium batteries is discharged from dehumidification holes, so that the effects of drying the lithium batteries in the fixing cylinders, achieving small space, keeping the high temperature for a long time and improving the drying efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a high-efficiency drying device for lithium battery production. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive and negative electrode materials and uses non-aqueous electrolyte solution. With the development of science and technology, lithium battery has become the mainstream. In the production process of lithium battery, lithium The battery is dried to maintain its stable performance. [0003] Lithium battery drying equipment currently on the market generally puts a lot of lithium batteries in a drying box to dry directly. The hot air diffuses in a relatively large range, making it difficult to maintain the temperature. It takes a long time to dry, resulting in low drying efficiency, and The accumulation of lithium batteries can easily lead to a smaller contact area between lithium batteries and ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-efficiency drying device for lithium battery production, which has the advantages of reducing the diffusion range of hot air and improving drying efficiency, and solves the problem of lithium battery drying equipment currently on the market. It is to put a lot of lithium batteries in the drying box and dry them directly. The range of hot air diffusion is relatively large, making it difficult to maintain the temperature. It takes a long time to dry, resulting in low drying efficiency, and the accumulation of lithium batteries is easy to cause contact between lithium batteries and hot air. The area becomes smaller and the drying is not complete
