基于挤出理论的螺旋挤压脱水机机理研究的中期报告摘要：本中期报告对基于挤出理论的螺旋挤压脱水机机理研究进行了初步探讨。文章首先对螺旋挤压脱水机的工作原理进行了简要介绍，并在此基础上推导了基于挤出理论的脱水机模型，包括物料流动方程、应变率方程和剪切应力方程。随后，我们研究了挺度、加热温度和螺旋转速对脱水机的影响。通过分析和实验验证，发现挺度对物料的脱水率有着重要的作用，而加热温度和螺旋转速则对物料的质量和干燥度有着影响。最后，我们对研究工作进行了总结并提出了进一步的研究方向。关键词：螺旋挤压脱水机；挤出理论；物料流动方程；应变率方程；剪切应力方程；挺度；加热温度；螺旋转速；脱水率；质量；干燥度Abstract：Thismidtermreportprovidesapreliminarydiscussiononthemechanismofascrewextrusiondewateringmachinebasedonextrusiontheory.Thearticlebrieflyintroducestheworkingprincipleofthescrewextrusiondewateringmachineandthenderivesamodelbasedontheextrusiontheory.Themodelincludesthematerialflowequation,strainrateequation,andshearstressequation.Next,westudiedtheeffectsofrigidity,heatingtemperature,andscrewspeedonthedewateringmachine.Throughanalysisandexperimentalverification,itwasfoundthatrigidityplaysanimportantroleinthedehydrationrateofthematerial,whileheatingtemperatureandscrewspeedhaveanimpactonthequalityanddryingdegreeofthematerial.Finally,wesummarizedtheresearchworkandproposedfurtherresearchdirections.Keywords:screwextrusiondewateringmachine;extrusiontheory;materialflowequation;strainrateequation;shearstressequation;rigidity;heatingtemperature;screwspeed;dehydrationrate;quality;dryingdegree.
