| 摘 要： | 粉体表面改性与复合设备是实现粉体表面改性与复合技术中的一个重要环节。在研究现有微纳米粉体表面改性与复合设备结构特点的基础上,结合微纳米粉体改性与复合的工作原理,针对微纳米粉体的表面特性,提出了机械混合法改性微纳米粉体的典型设备及其设计思想。本设计的特点在于在半椭球形容器下半部的圆柱面上设有两组8个与母线成α(α>90°)角的大小喷嘴成对角布置,以利于粉体和改性剂的分散与混合。

| Abstract: | The equipment of surface modification and complex of powder is an important device to accomplish the modification and complex process.The design thought of typical device for surface modification and complex of nano-sized and micron powders was supposed,which was based on the research of the structure characteristics of nowadays equipments and the operating principle of surface modification and complex of nano-sized and micron powder.In this designs,there were 2 groups(4 bigger and 4 smaller) spray nozzles under the half ellipsoid,and these nozzles was symmetry and opposite,each nozzle was α(α>90°)angle with the generatrices of the half ellipsoid so as to be beneficial to disperse and blend of powder and modifiers. |
