茶叶动态烘干机设计

茶叶动态烘干机设计摘要：该设计的内容为茶叶动态烘干机。近几年来随着我国经济的高速发展及人民生活的不断提高，中国茶饮业发展势头十分强劲，整体呈快速增长态势。该机具有机型小、成本低、安装维修方便、结构紧凑等特点。烘干机主要设计工作为：1,阐述了茶叶动态烘干机设计的目的和意义，概述了中国茶叶机械发展的基本现状。2.总体方案设计：茶叶经过输送带进入可以滚动的烘筒中，通过中心风管吹出的热风进行加热，经过烘干滚简的翻转使茶叶进行均匀的受热，最后达到所需的干燥度，由出茶口输出。3.烘干装置设计热风机将热风由中心风管输出对滚筒中的茶叶进行烘干。电机通过传动系统带动滚简转动使茶叶在烘干中受热均匀，以提高茶叶的品质并加快茶叶烘干速度。4.输送装置的设计输送装置的设计采用带轮传动和链轮传动，由带轮带动的输送带实现定量连续的供料。5.角度调整装置设计通过丝杠调整滚简的角度，由此来调整茶叶在滚简中的烘干时间，调整完后由调整机构锁紧。关键词：茶叶；烘干机：滚简Design of tea dynamic dryerAbstract:The content of this design is a dynamic tea dryer.In recent years,with therapid development of China's economy and the continuous improvement of people's lives,China's tea industry has a very strong momentum of development,showing a rapid growthoverall.The machine is characterized by small model,low cost,convenient installation andmaintenance,compact structure,etc.The main design work of the dryer is:1.The purpose and significance of the design of tea dynamic dryer are described,and thebasic status quo of the development of tea machinery in China is summarized.2.Overall scheme design:tea leaves enter the rolling drying cylinder through theconveyor belt,and are heated by the hot air blown from the central air duct.After the turningof the drying cylinder,tea leaves are heated evenly,and finally reach the required dryness,which is output from the tea outlet.3.Drying device designThe hot air blower outputs the hot air from the central air duct to dry the tea leaves in thedrum.The motor drives the drum to rotate through the transmission system,so that the tea isevenly heated during drying,so as to improve the quality of tea and accelerate the dryingspeed of tea.4.Design of conveyorThe conveyor is designed with pulley drive and sprocket drive,and the conveyor beltdriven by pulley realizes quantitative and continuous feeding.5.Design of angle adjustment deviceThe angle of the drum is adjusted by the lead screw to adjust the drying time of tealeaves in the drum.After the adjustment,the adjustment mechanism locks the tea leaves.Key words:tea;dryer;roller目录第1章绪论.1.1茶叶动态烘干机的设计意义1.2茶叶动态烘干机的研究现状…1.2.1茶叶动态烘干机的发展历史1.2.2茶叶动态烘干机的国内外研究现状..21.2.3茶叶动态烘干机需要解决的问题.3第2章茶叶动态烘干机的方案设计2.1设计任务分析2.1.1设计参数…42.1.2工艺路线2.1.3主要参数的确定2.2功能分析….42.2.1总功能的确定….42.2.2设计任务抽象化52.2.3功能分解.….52.2.4功能结构确定52.3功能分析..62.3.1分功能原理解..62.3.2系统方案求解….62.4方案评价…72.5系统方案原理图.….72.5.1总体结构布局….72.5.2输送装置….82.5.3热风形成输送机构….82.5.4转动烘干装置.92.5.5角度调整装置...10第3章传动系统设计计算.113.1电机选择113.2传动比分配113.3各轴功率、转速及转矩设计计算113.4传动零件的设计计算….123.4.1链传动设计计算.…..123.4.2轴的设计计算.153.4.3滚动轴承寿命计算.….193.5键联接的选择…20第4章执行机构零部件的设计计算214.1角度调整机构,214.2热风形成输送机构..224.3烘干滚筒机构方案设计….22第5章茶叶动态烘干机的安装、维护和安全要求245.1动态烘干机安装要求….245.2微波烘干技术24第6章结论,28致谢…。29参考文献…30
