The invention discloses a powder drying system, comprising a sealed drying oven, a vacuum pump, a seal tank, and a temperature control system. A vacuum pump joint is arranged on the body of the sealeddrying oven; the vacuum pump is arranged on the outer side of the sealed drying oven, and is communicated with the internal of the sealed drying oven through the vacuum pump joint; the seal tank is used for containing to-be-dried powder and is arranged in a cavity of the sealed drying oven, a stirring wheel assembly is mounted in the body of the seal tank and comprises stirring vanes disposed inthe body of the seal tank; the temperature control system comprises a temperature measuring device and a heating device disposed inside the sealed drying oven. The powder drying system can solve the technical problems of poor airtightness to powder, poor temperature uniformity and lack of temperature control in the production process of drying lithium battery powder.
Description
technical field [0001] The invention relates to the technical field of stirring systems, in particular to a powder drying system. Background technique [0002] With the increasing popularity of new energy vehicles, as one of the core components of new energy vehicles, the production process of lithium batteries needs to be improved urgently. In the drying production process of lithium battery powder, firstly, due to the limitation of the structure of the container, the vacuum requirement of the powder cannot be met, resulting in poor sealing of the powder, which has a great impact on the performance of the dried powder; secondly, due to Without a suitable mixing system, the composition uniformity and temperature uniformity of the dried powder cannot fully meet the product performance; third, there is no effective temperature control during the drying process, resulting in that the temperature uniformity after drying cannot meet the process requirements, affecting Product pe...
