摘要

根据声波团聚细粉试验的要求

设计出1台细粉螺旋给料机

并在初步计算的基础上

设计加工了3根外径相同、螺距不同的给料螺杆

以及独特的搅拌装置。通过试验标定

分析了给料速率与螺距、螺杆转速及搅拌速率之间的关系

发现存在一临界搅拌速率。试验结果表明

所设计的微量螺杆给料机能稳定和均匀地进行微量给料

可满足声波团聚细粉试验的要求

Abstract

Based on the requirements for acoustic agglomeration test of aerosol

a special screw type micro-feeder

which can feed fine powder material

has been designed

and on the basis of preliminary calculation

three feeding screw rods with identical diameter and different pitch of screws for said feeder

as well as a distinctive agitating facility being designed and fabricated.Through calibration in test

the relationship among the feeding velocity rate

the screw pitch

the revolution speed of screw rod

and the agitation rate has been analysed

and the existence of a critical agitation rate being discovered.Results of test show that the designed screw type micro-feeder can stably and uniformly perfom micro-feeding work

satisfying requirments of acousitic agglomeration of aerosol.
