Design and optimization on blade profile of vertical kneader
摘要
Abstract
In accordance with the weaknesses of the existing vertical kneaders'blades,based on the vertical kneader's kneading principles and movement characteristics,the existing hollow blades'modeling process was analyzed and evaluated,and new modeling method was proposed.Simulation analysis shows that the hollow blade's kneading range increases by approximately 31.5%.Take the solid blade's non-kneading surface was an example,on the basis of the mechanical properties of the blade,movement characteristics, and processing requirements,the modeling region of non-kneading surface was designed.The contour of the non-kneading surface is redesigned and treated by several circular arcs as well.Under the circumstance that the blade stiffness will not be weakened,simula-tion analysis shows the blade's maximum stress reduces by about 20%. By using the fresh design into practical blade design proce-dure,the mixing performance and mechanical property of the blade are greatly improved.关键词
