【正文】 1第 I 條 AbstractGraduate design of the entire contents is the design of a largescale absorption of aluminum vacuum ladle of the main design features and technical difficulties. With electrolysis technical transformation of the expansion project pleted ,To solve molten aluminum suction operating inefficiencies, molten aluminum heat loss big issue ,we need to develop bulk density of 4 6 tons without interim Ladle unlucky vacuum ladle.With the domestic large prebaked electrolyzer successfully developed, the current was gradually increased to 160 KA, 200KA. 280KA, 320KA, electrolyzer resulted in a significant increase in production of aluminum, aluminum vacuum suction small ladle has been unable to meet production needs.Sealing performance through the use of good, strong ability to prevent deformation of the ladle structure, High Life package and suction tubes lining and reasonably ascertain the location of shaft, so we will be able to achieve more satisfactory results.Papers used by the design of large aluminum vacuum suction Ladle institutions is conducive not only to better meet the needs of production, further improve the production efficiency and greatly enhance the production progress and hence involves the production proceeds. It as a production of intermediate process for the production of essential progress is essential to the production part.Key words: Ladle structure，vacuum ， jet 第 II 條 摘 要畢業(yè)設(shè)計(jì)的全部內(nèi)容設(shè)計(jì)為大型吸鋁真空抬包設(shè)計(jì)的主要特點(diǎn)與技術(shù)難點(diǎn)。隨著電解技改擴(kuò)建項(xiàng)目的完成 , 為解決鋁液抽吸運(yùn)轉(zhuǎn)效率低下、鋁液熱量損失大的問題，需要研發(fā)容重為46 噸無需中轉(zhuǎn)澆包倒運(yùn)的真空抬包。 2隨著國內(nèi)一些大型預(yù)焙電解槽的研發(fā)成功， 電流已陸續(xù)提高至160KA、200KA、280KA、320KA，電解槽產(chǎn)鋁量大增，小型吸鋁真空抬包已不能滿足生產(chǎn)的需要。通過采用密封性能好、防變形能力強(qiáng)的抬包結(jié)構(gòu)，使用壽命高的包襯和吸鋁管以及合理地確定轉(zhuǎn)軸的位置，這樣就能達(dá)到較為滿意的效果。采用論文中所設(shè)計(jì)的大型吸鋁真空抬包機(jī)構(gòu)不僅有利于更好地滿足生產(chǎn)的需求，進(jìn)一步提高產(chǎn)品的生產(chǎn)效率，大大地提高生產(chǎn)進(jìn)度以及由此而牽扯到的生產(chǎn)收益問題。它做為一個(gè)生產(chǎn)的中間過程，對于生產(chǎn)的進(jìn)度來說至關(guān)重要，是生產(chǎn)所必不可少的一部分。關(guān)鍵詞：抬包結(jié)構(gòu)，真空度，噴射器目 錄摘要 .......................................................................................................................................?Abstract................................................................................................................................Ι?前言 .................................................................3 3 ...............................3 概況 ............................................................4 氧化鋁生產(chǎn)所取得的主要技術(shù)成就 ................................4 存在的主要問題 ................................................5 氧化鋁冶煉技術(shù)的發(fā)展方向 ......................................5 電解鋁生產(chǎn)技術(shù) ...................................................6 電解鋁所取得的主要技術(shù)成績 ....................................6 存在的技術(shù)問題 ................................................7 鋁電解技術(shù)的發(fā)展方向 ..........................................8 .82. 1. 大型吸鋁真空抬包的研發(fā) .........................................9．有待解決的主要關(guān)鍵問題 ..........................................9．解決這些問題所采用的方法 ........................................93. 研發(fā)工作的前提及進(jìn)行的條件 ...............................10．研究的前提與假設(shè) ...............................................10. 實(shí)驗(yàn)方案的擬定 ................................................10．基本概念和理論基礎(chǔ) .............................................114．主要部分的設(shè)計(jì)計(jì)算與校核 .................................154．1 抬包結(jié)構(gòu)設(shè)計(jì)校核 ...............................................15 真空度分析 .....................................................17 電動機(jī)的選擇 ....................................................18 選擇電動機(jī)的種類，類型和結(jié)構(gòu)形式 ...............................19 選擇電動機(jī)的功率(容量) .........................................19 確定電動機(jī)的轉(zhuǎn)速 ...............................................195．結(jié)構(gòu)設(shè)計(jì)部
