基于ANSYS的中药浸膏微波真空干燥罐体的结构优化

Analysis of Chinese Medical Concrete Microwave Drying Equipment Based on ANSYS Optimization Design Research

针对中药浸膏微波真空干燥设备工作时出现的封板反复变形及旋转轴与封板连接处气体泄漏的问题,文章基于ANSYS的手段和理论分析,设计了旋转轴支撑方式的封板以及旋转密封与平面密封相结合的密封方式,优化了中药浸膏微波真空干燥罐体的结构。改进后的设备结构受力均匀,最大应力发生在封板近中央处,封板的变形及设备漏气的问题得到了有效的控制。优化设计提高了设备的安全性及可靠性。

In order to solve the problem of sealing plate repeated deformation and the gas leak at rotating plate for traditional medicine extract microwave vacuum dry equipment,the way of support of rotary shaft seal plate and the combination of the seal rotary with that sealing were designed based on ANSYS means and theoretical analysis,optimal structure of the equipment was obtained.The improved device structures can ensure stability and power equality,the maximum stress occurs near the center of the seal plate,seal plate deformation and the leak problem are effectively controlled,the safety and realiability of the equipment are improved.
