Innovation design of sealing structure of incineration ash treatment equipment

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.
