夹套反应釜总装图
摘要
搅拌反应釜，在化工、科研、食品等行业中应用范围广，操作非常简单便捷，安全系数符合要求。它的作用是在为各类反应准备反应发生的空间以及条件，让反应得以顺利进行。
4连续搅拌釜式反应器是我的本次设计课题，釜体、搅拌装置、传动装置、轴封以及其他零件是所有釜式反应器的重要的构成部分，当然也包括我这次设计的连续搅拌釜式反应器。对任务书进行了详细的分析之后，其要求和其结构特点都确定了，再对工作装置初步分析，开始实际确定设计方案，首先需要确定的是该反应釜筒体的尺寸数值，根据筒体的尺寸分析选择所需要的夹套。搅拌装置是设计的第二大部分，根据分析已经确定好的筒体，加上任务书的要求，将搅拌器和搅拌轴进行一个粗略的选择，接着通过计算强度和强度校核，再进一步确定一个最为恰当的装置。传动装置是该反应釜的三大部分之一，分析计算之后确定的电动机与减速机需兼容经济性与动力效果。接着设计反应釜的轴封，比较并选择轴封装置类型，对机械密封的结构、工作原理进行准确的分析。
本次设计表达了搅拌式反应釜的设计过程与工作过程。设计的反应釜在结构上安全可靠，性能良好，对化学反应过程具有很好的保护作用。在经济上，提高了化学反应的效率，从而提高了生产效率，节约生产成本。

ABSTRACT
Stirred reaction kettle, in the chemical industry, scientific research, food and other industrieswide range of applications, operation isvery simple and convenient, safety factor to meet the requirements. Its role is to prepare responses forvarious reactions to the space and conditions that allow the reaction to proceed smoothly.
4m^3 continuous stirred kettle reactor is my graduation project, kettle body, stirring device, transmission device, shaft seal and other parts are the important components of all kettle reactor, of course, including my design of the continuous stirred kettle reactor. A detailed analysis of the teacher's given task book the design of the reaction Kettle has a preliminary understanding of its requirements and its structural characteristics have been determined, and then the initial analysis of thework device, start to determine the actual design, the first thing to determine the size of the reactor cylinder, the number of the case, the specification has been given, According to the size of the cylinder to select the desired jacket, then the size of the jacket also know. The stirring device is the second most of the design, based on the analysis of the identified cylinder, plus the requirements of the task book, the mixer and the stirring shaft for a rough selection, and then through the calculation of strength and strength check, and then further determine the most appropriate device. The transmission device is one of the three parts of the reaction kettle, and the electric motor and the reducer must be compatiblewith economy and dynamic effect after the analysis and calculation. Then, for the design of the axial seal of the reactor, the type of shaft seal device is compared and selected, and the structure andworking principle of the mechanical seal are analyzed accurately.
This design expresses the mixing reaction kettle design process andwork process. The design of the reactor is safe and reliable in structure, good in performance, and has a good protective effect on the chemical reaction process. In economy, the efficiency of chemical reaction is improved, the production efficiency is improved and the cost of production is saved.
