气固分离称重料仓的设计与模拟分析

Abstract

针对当前通用型称重料仓工艺烦琐和设备复杂的问题，以大豆为例，运用模块化集成设计理念，采用理论分析与仿真模拟相结合的方法，设计开发了一套集卸料器与料仓于一体的气固分离称重料仓。采用Solidworks三维建模软件将设备各部分构件建模，运用计算流体力学及离散项模型对气固分离称重料仓的关键结构进行分析。结果表明，设计的气固分离称重料仓在完成称重卸料的同时可分离轻杂，简化了称重卸料过程，新增的蝶阀模块可根据料仓内的物料量动态调整进出仓过程。综上，设计的气固分离称重料仓可用于气力输送大豆的称重卸料。 Aiming at the problems of the cumbersome process and complicated equipment of the current general-purpose weighing silo, taking soybean as an example, using the modular integrated design concept and the method of combining theoretical analysis and simulation, a set of gas-solid separation equipment for weighing silo integrating unloader and silo was designed and developed. The Solidworks 3D modeling software was used to model each part of the equipment. The key structure of the gas-solid separation equipment for weighing silo was analyzed by computational fluid dynamics and discrete phase model. The results showed that the designed gas-solid separation equipment for weighing silo could realize the separation of light impurities while completing weighing and discharge, and simplified weighing and discharge process. The newly added butterfly valve could dynamically adjust the process of inlet and outlet according to the amount of material in the silo. In conclusion, the designed gas-solid separation equipment for weighing silo can be used for weighing and unloading of pneumatically conveyed soybeans.
