Finite Element Analysis of Screw Conveyor of Horizontal Screw Centrifuge with Large Aspect Ratio

The drum and screw conveyor of Horizontal Screw Centrifuge with Large Aspect Ratio are modeled by SolidWorks.FEA simulation was conducted by a finite element analysis software-Simulation embedded in SolidWorks,Mode and static monolithic structure of the screw conveyor under the normal working state was analysed.The 5 rank frequencies,stress distribution,the radial and axial deformation were obtained.Through changing parameters such as the lead 、the half cone angle rotational speed and the blade thickness,the paper investigates the impact of parameters on the strength,displacement and vibration form,in order to realize the optimization of centrifuge.The comparison between the common drum with the Large Aspect Ratio one was implemented,the paper finds that the former has a better separation capacity,better stress and deformation distribution of screw conveyor and the rotors has higher critical speed.
