摘要： 研制高可靠的密封结构对推动焚烧灰处理装备的工业化有着极其重要的作用。基于对现有密封结构的分析，利用TRIZ （Teoriya Resheniya Izobreatatelskikh Zadatch，发明问题解决理论）提出了一种主密封与辅助密封相结合的双密封方式，创新设计了适用于远程控制的焚烧灰处理装备密封结构，有效解决了焚烧灰处理装备的密封问题。建立新型密封结构的性能评价指标及其计算公式，并根据焚烧灰处理装备的使用工况进行了密封性能分析。采用有限元分析方法对该密封结构进行了仿真分析，通过参数优化确定了最终创新方案。实际应用结果表明，所设计的新型密封结构能满足小时泄漏率4级标准，对接平台与标准钢桶的对中精度较高。相比现有密封结构，其整体性能得到显著提高，已在焚烧灰处理装备中得到良好应用。
Abstract: The development of highly reliable sealing structure plays an extremely important role in promoting the industrialization of incineration ash treatment equipment. Based on the analysis of the existing sealing structure, a double sealing mode combining main sealing and auxiliary sealing was proposed by using TRIZ (Teoriya Resheniya Izobreatatelskikh Zadatch, i.e. inventive problem-solving theory). The sealing structure of incineration ash treatment equipment suitable for remote control was innovatively designed, which effectively solved the sealing problem of incineration ash treatment equipment. The performance evaluation index and calculation formula of the new sealing structure were established, and the sealing performance was analyzed according to the service conditions of incineration ash treatment equipment. The finite element analysis method was used to simulate and analyze the sealing structure, and the final innovative scheme was determined through parameter optimization. The practical application result showed that the designed new sealing structure can meet the level 4 standard of hourly leakage rate, and the alignment accuracy between the docking platform and the standard steel barrel was relatively high. Compared with the existing sealing structure, its overall performance had been significantly improved and had been well applied in incineration ash treatment equipment.
