【摘要】：本論文以某企業(yè)電解廠中的硫酸銅攪拌設(shè)備為研究對(duì)象,其攪拌裝置在正常工況下長(zhǎng)時(shí)間工作時(shí),會(huì)出現(xiàn)攪拌槳葉和攪拌軸彎曲、斷裂,以及軸承的損壞,從而影響了硫酸銅的生產(chǎn)效率和質(zhì)量。因此,攪拌裝置的結(jié)構(gòu)改進(jìn)對(duì)于提高攪拌效果、減少攪拌設(shè)備的維修費(fèi)用和經(jīng)濟(jì)損失是至關(guān)重要的。本論文通過(guò)詳細(xì)調(diào)研原攪拌裝置工況,找出其結(jié)構(gòu)中存在的問(wèn)題。針對(duì)攪拌軸在旋轉(zhuǎn)的過(guò)程中出現(xiàn)明顯的角度及橫向的偏移問(wèn)題,建立兩種結(jié)構(gòu)模型,并利用仿真軟件Fluent和ANSYS Workbench對(duì)這兩種結(jié)構(gòu)模型進(jìn)行CFD和FSI數(shù)值模擬分析,驗(yàn)證原攪拌裝置結(jié)構(gòu)是否會(huì)導(dǎo)致其失效。根據(jù)分析結(jié)果,并結(jié)合理論對(duì)攪拌裝置進(jìn)行結(jié)構(gòu)改進(jìn)。首先,通過(guò)對(duì)攪拌槳不同安裝高度及不同層間距的攪拌性能進(jìn)行研究,得出最優(yōu)的攪拌槳的結(jié)構(gòu)設(shè)計(jì)。其次,根據(jù)攪拌裝置的工作特性,選擇合理的攪拌軸支撐方式,并結(jié)合實(shí)驗(yàn)與理論數(shù)據(jù),得出最佳的軸承間距。最后,對(duì)結(jié)構(gòu)改進(jìn)后的攪拌裝置進(jìn)行數(shù)值模擬分析及實(shí)際生產(chǎn)運(yùn)用。全文對(duì)原攪拌裝置進(jìn)行結(jié)構(gòu)分析及改進(jìn),并通過(guò)實(shí)際生產(chǎn)運(yùn)用,得出改進(jìn)后的攪拌裝置在工作過(guò)程中更加穩(wěn)定,并且能夠大大提高攪拌效率及使用壽命。
[Abstract]:In this paper, the copper sulfate mixing equipment in an enterprise electrolytic plant is taken as the research object. When the mixer works for a long time under normal working conditions, the agitating blade and shaft will bend, break, and the bearing will be damaged. As a result, the production efficiency and quality of copper sulfate are affected. It is very important to reduce the maintenance cost and economic loss of the mixing equipment. To find out the problems existing in the structure, aiming at the obvious angle and lateral deviation of the agitated shaft in the course of rotation, two kinds of structural models are established. The simulation software Fluent and ANSYS Workbench are used to simulate and analyze the two structural models by CFD and FSI to verify whether the structure of the original mixer will lead to its failure. According to the results of the analysis and combining with the theory, the structure of the mixing plant is improved. Through the research on the mixing performance of the impeller with different installation heights and different layer spacing, the optimum structure design of the agitator is obtained. Secondly, according to the working characteristics of the agitator, a reasonable supporting mode of the agitator shaft is selected. Combined with the experimental and theoretical data, the best bearing spacing is obtained. Finally, the numerical simulation analysis and practical production application of the improved mixing device are carried out, and the structure analysis and improvement of the original mixing device are carried out in the full text. Through practical production and application, it is concluded that the improved mixing device is more stable in the working process, and can greatly improve the mixing efficiency and service life.
