Abstract

The article presents research materials to ensure an increase in the intensity of purification of raw cotton from fine litter in a ginnery. It is indicated that in existing cleaners of raw cotton from impurities, the process is mainly carried out due to the shock-disintegrating effect of the working bodies of the machine on the processed material. To improve the efficiency of cleaning raw cotton from fine litter, it is proposed to use a cleaner with different types of working bodies, and such a combined fine litter cleaner consisting of a ring and screw working body has been developed. Experimental studies have found that with the use of such a cleaner there is an increase in the cleaning effect by 5% (abs.). The theory of the movement of an isolated material point (leafjets of raw cotton) in a screw working body is considered. It has been determined that at an optimum angle of elevation of the helix, the maximum axial speed and productivity of the screw working body of the cleaner are ensured. It is indicated that the critical radii establish the boundaries of the regions where the material particles acquire the screw angular velocity and their axial displacement ceases.
带螺旋工作体的原棉清洗机
介绍了提高某厂细凋落物中原棉净化强度的研究材料。研究表明,在现有的原棉脱杂清洗机中,该工艺主要是由于机器工作体对被处理物料的冲击崩解作用而进行的。为提高精砂中原棉的清洗效率,提出采用不同工体的清洗机,并研制了一种由环形和螺旋工体组成的组合式精砂清洗机。实验研究发现,使用这种清洁剂后,清洁效果可提高5% (abs.)。考虑了螺杆工作体中孤立质点(原棉叶喷流)的运动理论。结果表明,在最佳的螺旋仰角下,可保证清洗机螺杆工作体的最大轴向转速和生产率。结果表明,临界半径确定了材料颗粒获得螺旋角速度和轴向位移停止区域的边界。
