摘要
Abstract
There are influences for environment and workers during powder packaging.So the automatic bag packaging machine of powder adds a dusting system.On the one hand,the process analysis was taken for particles in dust hood and the minus pressure,in the form of drag force of air,affect particles.What's more,by analysing fluid Reynolds Number the air velocity is confirmed as a fundamental factor affecting dusting.On the other hand,fluent is used to stimulate particles tracking and explore reasonable pumping velocity.When the velocity is too small to rise some part of particles,it adds suspended particles at the mouth of dust hood.And the exaggerate velocity also make the large particles suspended,which is difficult to fall.When the pumping velocity reach to 26-39m/s,it's the best effect to dusting.关键词
