【摘要】：传统的烧结环冷机存在漏风严重、散料收集难、故障点多等问题,冷却效果不理想,能耗高;并且环冷机的密封橡胶损坏快、密封不严,不能适应回转框架的跑偏。因此,本论文根据环冷机工作原理,借鉴磁性流体液密封基础理论,设计一款密封可靠、漏风率低、能源消耗少、结构紧凑、维护工作量小、作业效率高的新型液密封环冷机,有意义。本文主要内容是:首先,通过阅读国内外文献及其他资料,结合本企业环冷机研制成果,总结分析了国内外环冷机的发展现状及存在的问题。基于分析的传统环冷机存在的问题,简要分析了新型环冷机的工作原理及其总体设计,然后通过Solidworks绘图软件建立台车三维模型,并应用Gambit软件对其进行网格划分,然后利用CFD软件FLUENT对环冷机台车的网格模型进行求解,从而分析其温度场、速度场和压力场对冷却效果及其冷却周期的影响,最终设计出冷却效果良好的台车;并详细的阐述了新型环冷机其他结构的设计过程,包括驱动装置、回转框架、密封装置、鼓风系统、环形风道装置、给料装置的设计过程。其次,系统的研究和分析了新型环冷机的安装工艺。简要分析了新型环冷机的安装工艺流程,并绘制了新型环冷机安装工艺流程图,重点阐述了新型环冷机主要零部件的安装工艺,包括环冷机的中心标桩、环冷机骨架、传动支架、水平轨道、侧轨、台车及密封装置、环形风道液槽、风道密封装置、驱动装置、给料溜槽、鼓风系统的安装工艺。最后,为了检查新型环冷机是否满足工艺要求,是否能够实现既定的功能,对其进行了一系列的测试。测试结果发现了一故障问题,接着针对这些故障问题,研究了其对应的处理方法,包括距联轴器打滑、摩擦轮打滑、回转框架台车的侧辊与侧轨接触异常以及风道门型密封装置异常问题。
[Abstract]:The traditional sintered ring cooling machine has many problems such as serious air leakage, difficult collection of bulk materials and many fault points. The cooling effect is not ideal and the energy consumption is high. The sealing rubber of the ring cooler is damaged quickly, the seal is not strict, and can not adapt to the deviation of the rotary frame. Therefore, according to the working principle of the ring cooling machine and the basic theory of magnetic fluid liquid seal, this paper designs a reliable seal. Low air leakage rate, less energy consumption, compact structure, small maintenance workload, high operational efficiency of a new type of liquid seal ring cooler, the main content of this paper is: first, through reading domestic and foreign literature and other materials. Based on the research results of the ring cooling machine in our enterprise, the development status and existing problems of the ring cooling machine at home and abroad are summarized and analyzed, and the existing problems of the traditional ring cooler based on the analysis are summarized and analyzed. This paper briefly analyzes the working principle and the overall design of the new ring cooling machine, then establishes the three-dimensional model of the car by Solidworks drawing software, and uses Gambit software to mesh it. Then CFD software FLUENT is used to solve the grid model of ring cooling lathe, and the effects of temperature field, velocity field and pressure field on cooling effect and cooling cycle are analyzed. Finally, a car with good cooling effect is designed. And described in detail the design process of other structures of the new ring cooler, including driving device, rotary frame, sealing device, blast system, annular air duct device, feeding device design process. Secondly. The installation technology of the new ring cooler is studied and analyzed systematically. The installation process of the new ring cooler is briefly analyzed, and the installation process flow chart of the new ring cooling machine is drawn. The installation technology of the main parts of the new type ring cooler is expounded, including the central standard pile of the ring cooler, the frame of the ring cooler, the transmission support, the horizontal track, the side rail, the trolley and the sealing device, the annular air duct liquid tank. Air duct seal device, drive device, feed chute, blast system installation technology. Finally, in order to check whether the new type of ring cooling machine meets the process requirements, can achieve the established functions. A series of tests were carried out. A fault problem was found in the test results. Then, the corresponding treatment methods were studied, including the slip of the distance coupling and the sliding of the friction wheel. The abnormal contact between side roll and side rail and the abnormal sealing device of air duct type of rotary frame car are discussed.
