摘要
近年来,随着新能源锂电池产业的兴起和快速扩张,密封回转炉在锂电池材料各个生产工艺环节中得到了广泛应用。密封装置作为回转炉设备的重要组成部件,其性能优劣直接决定了设备工艺稳定性。近年来兴起一种石墨环轴向压紧密封结构,并通过迅速的技术迭代优化,目前已经发展成为一种新型的回转炉密封结构。在对当前石墨环轴向压紧密封结构进行利弊分析的基础上,提出了优化改进结构方案,解决了密封装置加工精度严苛、安装调试困难、密封面贴合效果不好、石墨材料容易被氧化等问题。通过实践和对比测试数据发现,新的密封结构各项密封性能显著提高,大幅提升了密封装置的密封性、耐用性、稳定性和可维护性,为进一步提升锂电材料用回转炉工艺技术水平打下了基础。
In recent years,with the rise and rapid expansion of the new energy lithium battery industry,sealed rotary furnaces have been wide-ly used in various production processes of lithium battery materials.As an important component of rotary furnace equipment,the performance of the sealing device directly determines the process stability of the equipment.In recent years,a graphite ring axial compression sealing struc-ture has emerged,and through rapid technological iteration optimization,it has now developed into a new type of rotary furnace sealing struc-ture.Based on the analysis of the advantages and disadvantages of the current axial compression sealing structure of graphite rings,it proposes an optimized and improved structural scheme,which solves the problems of strict machining accuracy,dficult installation and debugging of sealing devices,poor sealing surface adhesion effect,and easy oxidation of graphite materials.Through practice and comparative testing data,it has been found that the new sealing structure significantly improves the sealing performance of various aspects,greatly enhancing the seal-ing,durability,stability,and maintainability of the sealing device,laying a foundation for further improving the technology level of rotary fur-naces for lithium battery materials.
