Title A Three-dimensional Structure Design of centrifugal blender
Abstract
On the basis of the analysis of the function and performance of the centrifugal blender, also refer to a large amount of material, the general structure of the design scheme of the centrifugal blender is formulated. The motor drives the rotation of the spindle, and then through corresponding connecting pieces drive the tube to rotate, realizing the function of centrifugal. Cam and guide bar mechanism is used, through the rotation of the cam drives the guide rod guide, in reciprocating motion, driving tube pitch motion, realizing the stirring function. Use the characteristic of the unidirectional overrunning clutch that it can reverse separable ,achieving the centrifugal and stirring of non-interference and step by step. Double direction thrust bearing is used to realize the corresponding parts’ vertical orientation and support. In order to prevent overrunning clutch’s rotating in the reverse rotation due to friction with the inner, design also includes positioning system, use the speed sensor -- encoder and photoelectric sensors and the electromagnet to achieve the corresponding parts of the fixed position, achieving the stirring and centrifugal function without mutual interference. Finally using Pro/E for three-dimensional modeling, and draw out the2D engineering drawings.

在现代工业中，离心分离技术已经越来越重要。这不仅由于离心机和其他机械相比，可得到含湿量低的固相和高纯度液相，而且可以减轻劳动强度，改善劳动条件，并且具有连续运转，自动控制，占地面积小等优点。搅拌机在这方面更是如此，而且两者现结合起来的装备更是能在化学工业，医疗卫生，科学研究等诸多方面发挥巨大的作用，特别是随着环保、能源和生物医药工程的发展，更促使了我国离心分离技术的迅速发展。本说明书通过浅述离心搅拌机在生产和生活中的实际意义，明确了本课题的研究方法，即通过AutoCAD以及Pro/E对离心搅拌机进行科学的三文设计。
