摘 要
该毕业设计题目是机械翻倒离心机的设计。在老师的悉心指导下，我进行了转鼓壁的厚度计算，拦液板的计算，转鼓底的设计，功率计算和电动机的选择，传动皮带的设计及选择，主轴的设计和强度校核，轴承的选择，翻到架的设计和强度计算，刹车的结构设计和强度计算，翻倒传动部分的设计计算，和其它的一些设计计算。
在设计中，我首先要了解到离心机的工作原理：先由控制电路接通带动转鼓转动的电动机，通过皮带的传动使转鼓转动，转鼓转动使物料固液分离，液体通过离心机底部的排液管流出，固体留在转鼓壁上，然后再由控制电路接通翻倒电动机使离心机翻转倒出固体，这样就完成了分离的整个过程，这也是我们设计必须明白的。然后使了解离心机的各个零部件的构造和它们的材料工艺要求。最后对离心机进行整体的评定。
通过检测分析离心机（使用稳定性分析仪）在整个样品高速传输，对沉降或气浮（膏）进行概要分析，它描述了一个实用多元化的分散剂和乳液。它也阐明了如何使用推算出的结果，来估计在引力场中的分散性样品的稳定的货架寿命。配方优化，如选择合适的表面活性剂的水平，也证明了这种方法的实际应用
“稳定或不稳定”，往往是要求在日常的生产过程中控制不同类型的分散（例如，颜料悬浮液，泥浆，农业化学和制药乳液）以及在研发部门的工作过程中处理新型添加剂的相关配方研发问题。稳定的含义，在很大程度上取决于某一特定产品的顾客要求。在一般情况下，可以被描述为“稳定”的化学变化或物理变化（至少对于一个给定的一段时间）后的质量。
我们往往通过一些最直接的方法，如简单的“试管试验”来检测并通过肉眼或通过特殊的固定或移动传感器的分相对发生的现象进行分类和量化。而与肉眼观察相比传感器的应用，使实验结果更加客观的，并解决了很多肉眼观察结果无法解决问题，尤其是在相当稳定分散的情况下的计时问题。因此，一方面，经常采用间接方法确定颗粒大小或电泳迁移率与稳定段米。尽管测量的问题，尤其是较高和非常高的体积浓度，得到的结果让没有直接的稳定性参数，如选择沉淀或悬浮速度计算。另一方面，分层现象可能被加快离心机手段和记录的粒子浓度的变化，在以整个样本量为离心时间的功能将提供有关粒子迁移的信息相对应，沉淀与分散稳定性。

Abstract
The graduation project entitled machine overturned centrifuge design. I was the drum wall thickness, the board of the bar, the drum at the end of the design, calculation and electrical power of choice, transmission belt of the design and selection, Spindle in the design and strength check, bearing the choice, turn-the design and strength, braking and intensity of the structural design, overturned part of the design of transmission, and a number of other design and calculation. Zhang jianwei teacher the guidance of well。 In the design, I would first need to understand that the centrifuges working principle: first control circuits connected to the motor rotating drum driven by the belt drive to drum rotation, rotating drum so that materials from solid to liquid, liquid by centrifugal - Ranked at the bottom of the outflow of liquid, solid remain in the drum wall, and then overturned by the motor control circuits connected centrifuges to Dispose of solid turnover, thus completing the separation of the whole process, which is designed to be Understand. And then to the various components of centrifuges to understand the structure and process their materials requirements. Finally, the centrifuges to conduct an overall assessment。
The analysis of sedimentation or flotation (creaming) by detecting the transmission profile over the entire sample height in an analytical centrifuge (using a Stability Analyzer) is described and illustrated for a diverse range of practical dispersions and emulsions. It is also illustrated how to use extrapolated results to estimate dispersion shelf life stability for samples in a gravitational field. Formulation optimization, such as choosing appropriate surfactant levels, is also shown to be a practical application of such methods.
‘‘Stable or unstable’’, that is often the question asked in the daily production quality control of different types of dispersions (e.g., pigment suspensions, slurries, agro-chemical and pharmaceutical emulsions) as well as in R&D departments dealing with new additives or formu-lations. The definition of the meaning of stability depends very much on the customer requirements for a given product. In general, ‘‘stable’’ may be described as the quality of being free from change or variation (at least for a given time period)
If we are dealing with disperse systems, such as suspensions or emulsions, instability phenomena are, on the one hand directly related to a possible migration of particles (sedimentation, flotation), or on the other hand, to changes in particle size distribution (e.g., due to particle interaction) followed over the total length of the cell containing the dispersion and auto-matically determines the time dependence of the position of the interface particle free fluid=suspension or sediment by a special algorithm. Results are presented which demonstrate stability prediction at a very accelerated rate for different dispersions at their original concentra-tion. It will be shown furthermore that the recorded transmission profiles allow one to characterize dispersed particles regarding smallest deviations in size and to quantify the degree of polydispersity at high volume concentrations.
