摘要
葵花籽是一种重要的油料作物,脱籽是葵花生产加工中一个重要的环节,而清选装置对籽粒的收集起着至关重要的作用,针对现有葵花脱籽机清选装置存在的问题,设计了风选式的清选装置,利用一定的风速实现葵花籽与杂质分离,并采用FLUNT对清选装置进行流场分析,得出当风选机构转速在900 r/min时,能够较好实现清选效果。
Sunflower seeds are an important oil crop,de-seeding is an important link in the production and processing of sunflower,and the cleaning device plays a vital role in the seeds collection.Aiming at the existing problems in selection device of the sunflower seed thresher,the air separation type cleaning device is designed in this paper.This device uses a certain wind speed to separate the sunflower seeds from impurities and achieves threshing;and the FLUNT is used to analyze the flow field of the cleaning device.The results show that the cleaning effect can be better achieved as the speed of the air selection mechanism is 900 r/min.
