摘　　要：为实现浆体膨胀复合材料自助化制浆装置安全生产与高效制浆,创建了一个包含膨胀复合粉料相关参数的储料仓力学模型,根据充填浆体浓度配比及实际生产的相关要求进行了关键参数设计,确定出了仓体流型、容积、最大半顶角、最小卸料口径。并利用有限元法对储料仓进行结构强度分析,得出其在全载下位于圆柱圆锥连接处的最大应力、应变。工程应用表明,该储料仓可实现混料、储料、卸料等功能,保证了制浆装置的连续制浆与浆体质量,并为储料仓系列化生产提供了理论依据。In order to achieve stfety in production and high effective preparation of slurry, a storage silo mechanical model including placing composite expansion slurry parameters was created. According to concentration ratio for filling slurry and requirements of actual production, the parameters of storage silo＇s flow pattern, volume, maximum half apex angle and minimum discharge aperture were determined. Structural strength of storage silo under the fhll loads was analyzed by finite element method to gain the maximum stress value and strain value which located in the connection of cylinder cone. Application results showed that mixing, storing and unloading material was implemented and continuous pulping and the quality of slurry ware ensured when using the storage silo. And the theoretical basis for the storage of series production was provided.
