推进剂药粒水平振动干燥实验
|
摘要
介绍了一种推进剂药粒水平振动连续干燥方法。经过大量的工艺实验,通过调节螺旋加料量、水平振动干燥器振动振幅及频率,探讨了物料在水平振动干燥器内停留时间与温度及水分之间的关系,以及连续干燥的工艺参数对整体工艺的连续性及有效匹配性的影响。在工艺实验中,改进了水平振动干燥器不合理的结构,解决了夹套漏水及物料滞留等技术问题。最佳干燥条件下被干燥后物料的物性参数可满足最终压伸工艺要求。
A horizontal vibration continuous drying method of propellant granule was introduced. Based on a large number of process experiments, the relationship among the material residence time in the horizontal vibration drying apparatus, temperature and water content was studied, and the influence of technological parameters of the continuous drying on the continuity and effective matching ability of the whole process was also investigated by adjusting screw feeding quantity, vibration amplitude as well as frequency of horizontal vibration drying apparatus. The unreasonable structure of the horizontal vibration drying apparatus was improved, and the technical problems of jacket water leakage, material retention, etc. were solved in the process experiment. The property parameters of dryed materials under the optimum drying condition can meet the requirements of final extrusion process.
