玻璃生产线及其温度控制系统设计

i玻璃生产线温度控制系统设计摘要本文介绍了对传统玻璃生产线退火窑输送装置的改进及其温度控制系统完善的设计过程。文中首先对玻璃生产线退火窑的国内外发展现状，以及其温度控制系统的结构组成和原理进行了简单介绍。然后针对连续式退火窑的结构特点，设计了一套可灵活改变输送装置的三维输送机构。结合转位机构的特点，采用步进电机带动齿轮副，实现各输送装置的灵活转换。各类输送装置速度的调节是采用PLC控制变频器来实现的。在温度控制系统的设计方面，本设计在退火窑各个温度区均采用周波控制系统，来对各温度区进行温度调节。设计后的退火窑和温度控制系统可以在提高玻璃制品生产效率的同时，也可使退火窑的退火质量得以优化。关键词：退火窑，输送装置，转位机构，温度控制系统，PLC控制iiProductionlineoftheglassannealingkilnanditstemperaturecontrolsystemdesignAbstractThispaperintroducesthetraditionalglassproductionlineannealingkilnfeedingdeviceandtheimprovementofthetemperaturecontrolsystemdesignprocess.Inthispaper,glassproductionlineannealingkilndevelopmentstatusathomeandabroad,aswellasitstemperaturecontrolsystemstructureandprinciplewereintroduced.Thenaccordingtothecontinuousannealingkilnstructurecharacteristics,designasetofflexiblechangeofthree-dimensionalconveyingmechanismconveyingdevice.Combinedwiththeindexingmechanismcharacteristics,usingasteppermotortodrivethegearpair,eachconveyingdevicerealizeflexibleconversion.VarioustypesofconveyorspeedadjustmentistheuseofPLCcontroloffrequencyconvertertorealize.Inthetemperaturecontrolsystemdesign,thedesignofeachtemperaturezoneinannealingfurnaceadoptsfrequencycontrolsystem,toeachtemperaturezoneisusedfortemperatureregulation.Designofannealingfurnaceandtemperaturecontrolsystemtoimprovetheglassproductsproductionandefficiencyatthesametime,alsocanmaketheannealingfurnaceannealingqualitycanbeoptimized.Keywords:annealingkiln,conveyingdevice,indexingmechanism,temperaturecontrolsystem,PLCcontrolI目录第一章绪论.....................................................................................................................11.1概述...............................................................................................................................11.2国内外发展现状及趋势...............................................................................................11.3退火窑的基本结构和温度控制系统的工作原理.......................................................31.3.1退火窑的基本结构....................................................................................................31.3.2温度控制系统的工作原理........................................................................................41.4设计方案的改进..........................................................................................................51.5本设计的主要完成的任务..........................................................................................6第二章关于玻璃生产线退火窑的设计...........................................................................72.1玻璃的退火与退火窑..................................................................................................72.1.1退火的概念、目的和过程.......................................................................................72.1.2玻璃制品内应力的类型及成因................................................................................72.2退火窑的分类及要求..................................................................................................82.2.1退火窑的分类...........................................................................................................82.2.2对退火窑的要求.......................................................................................................92.3退火窑的分区..............................................................................................................92.3.1保温区（A区、B区、C区）.................................................................................92.3.2缓冷区（D区、E区）...........................................................................................102.3.3快冷区（F区）.......................................................................................................102.4退火窑输送装置的改进............................................................................................102.4.1传统退火窑输送装置的介绍..................................................................................102.4.2改进后的退火窑三维输送装置.............................................................................112.4.3主要零部件的设计计算与说明.............................................................................13第三章温度控制系统的硬件组成及软件设计...........................................................163.1温度控制系统的硬件组成........................................................................................16II3.1.1可编程控制器（PLC）的简介、选用及端口分配..............................................163.1.2变频调速器的应用.................................................................................................173.1.3热电偶的概述及工作原理.....................................................................................183.1.4周波控制系统的组成、原理及性能分析.............................................................193.1.5温度控制系统的硬件组成及性能分析.................................................................203.2温度控制系统的软件设计.........................................................................................213.2.1软件部分的组成及分析.........................................................................................213.2.2顺序功能图.............................................................................................................223.2.3梯形图...................................
