糖粉分离器的结构优化设计

为了分析糖粉收集过程中,分离器分离效果不佳的现象,采用Fluent软件对糖粉分离器进行仿真分析。基于现有结构,分别改变分离器出口结构、增加分离器高度、减小分离器筒径、筒内装置螺旋导流叶片,比较不同结构对分离器分离效果的影响,并讨论了进风方式对分离器分离效果的影响。研究结果表明,糖粉分离器靠近出口段分离能力较弱,导致风机口糖粉喷出;装有螺旋导流叶片较其他结构更有利于分离能力的提高;进风方式对分离效果有一定影响,采用进口通入空气的方式,比出口抽吸空气的方式分离效果好,但进风方式对糖粉分离器分离能力影响相对较小;带有螺旋导流叶片的糖粉分离器更加适合糖粉的收集与分离。

Structural optimization design of sugar powder separator

To explain the phenomenon of poor separation effect of powder separator in the process of collecting powdered sugar, simulation analysis of powder separator was made with using Fluent software. Based on the existing structure, changing the outlet structure, increasing the height, reducing the diameter of the separator and installing spiral guide vane respectively, to make comparison of the effects of different structures of separator. In addition, the influence of air intake mode is discussed. Weak separation capacity close to separator outlet section leads to powder splash; Equipped with spiral vanes is more conducive to improve the separation capacity than other separator structure; Air intake mode has some influence on separation effect, using imported air way contributes to separation effect than export suction air way, but air intake mode has less effect on the separation ability of sugar powder separator; Sugar powder separator with spiral guide vane is more suitable for collection and separation of sugar.
