[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.
