【摘要】：混凝土作為現(xiàn)代社會(huì)基礎(chǔ)建設(shè)的主要建筑材料,其質(zhì)量和使用效率的要求越來(lái)越高。雙臥軸強(qiáng)制式攪拌主機(jī)因其攪拌效率高、攪拌質(zhì)量?jī)?yōu)的突出特性成為當(dāng)今工程上使用量最多的混凝土攪拌設(shè)備。雖然雙臥軸強(qiáng)制式攪拌主機(jī)使用量最多但是由于其自身結(jié)構(gòu)比較復(fù)雜,雙臥軸強(qiáng)制式攪拌主機(jī)的攪拌效能優(yōu)化研究難度很大,國(guó)內(nèi)外對(duì)這一類型的主機(jī)設(shè)計(jì)多依賴經(jīng)驗(yàn)。本課題以老式JS1000主機(jī)為基礎(chǔ)根據(jù)其目前存在的缺點(diǎn)制定本次優(yōu)化的目標(biāo)。著重對(duì)本次優(yōu)化的傳動(dòng)裝置、攪拌裝置參數(shù)選取進(jìn)行分析計(jì)算。在設(shè)計(jì)取值時(shí)從攪拌機(jī)理入手,分析攪拌過(guò)程中物料顆粒的運(yùn)動(dòng)和變化形式,分析影響主機(jī)攪拌效能的主要結(jié)構(gòu)參數(shù),包括攪拌臂數(shù)目及布置形式、攪拌葉片安裝角、攪拌罐長(zhǎng)徑比、攪拌軸轉(zhuǎn)速等。確定本次優(yōu)化設(shè)計(jì)選取值：攪拌裝置參數(shù)為圍流排列、平行布置、正正排列、相位角60。、攪拌臂8個(gè)、攪拌葉片線速度1.6m/s、葉片安裝角40。。通過(guò)fluent軟件對(duì)優(yōu)化前后兩種攪拌主機(jī)攪拌時(shí)的流場(chǎng)進(jìn)行了仿真分析,確定了新型主機(jī)是否達(dá)到優(yōu)化目標(biāo)。又通過(guò)試驗(yàn)樣機(jī)的試驗(yàn)結(jié)果驗(yàn)證優(yōu)化方案參數(shù)選擇的正確性。再通過(guò)工業(yè)驗(yàn)證來(lái)確定其優(yōu)化效果。本課題通過(guò)理論分析、fluent軟件仿真分析及試驗(yàn)樣機(jī)試驗(yàn)相互印證,既發(fā)揮了理論分析和軟件仿真不受實(shí)驗(yàn)條件限制的優(yōu)勢(shì),又克服了模型理想化的局限,同時(shí)減少了試驗(yàn)的大量投資及縮減了試驗(yàn)時(shí)間,取得了很好的優(yōu)化效果,為新型雙臥軸強(qiáng)制式攪拌主機(jī)的設(shè)計(jì)研發(fā)提供了一種較好的方法,同時(shí)提供了部分理論依據(jù)及試驗(yàn)數(shù)據(jù)。通過(guò)工地實(shí)際使用驗(yàn)證效果,確定本次產(chǎn)品優(yōu)化取得了成功。
[Abstract]:As the main building material of modern social infrastructure construction, the quality and efficiency of concrete are more and more demanding. The outstanding characteristic of excellent mixing quality has become the most widely used concrete mixing equipment in engineering nowadays. Although the double horizontal shaft forced mixing machine is used the most, because of its complicated structure, It is very difficult to optimize the mixing efficiency of the double horizontal shaft forced stirring engine. The design of this type of mainframe at home and abroad depends on experience. Based on the old-fashioned JS1000 mainframe, this paper formulates the goal of this optimization according to its existing shortcomings. The parameters of the mixing unit are selected for analysis and calculation. In the design of the mixing mechanism, the movement and change form of the material particles in the mixing process are analyzed, and the main structural parameters that affect the stirring efficiency of the main engine are analyzed. Including the number and layout of the stirring arm, the angle of the blade, the aspect ratio of the mixing tank, the rotating speed of the mixing shaft, etc. The optimum design selection value is determined as follows: the parameters of the mixing device are circumfluence arrangement, parallel arrangement, positive arrangement, etc. The phase angle is 60. 0, the mixing arm is 8, the linear speed of the stirring blade is 1.6 m / s, and the blade installation angle is 40. The flow field of the two kinds of stirring engine before and after optimization is simulated by fluent software. It is determined whether the new mainframe can achieve the optimization goal, and the correctness of the parameter selection of the optimization scheme is verified by the test results of the experimental prototype. Then, the optimization effect is determined by industrial verification. This subject is analyzed by theoretical analysis of fluent software. The simulation analysis of the parts and the test of the prototype proved each other. Not only the advantages of theoretical analysis and software simulation are not limited by experimental conditions, but also the limitation of model idealization is overcome. At the same time, the investment of experiment is reduced and the test time is reduced, and good optimization results are obtained. It provides a better method for the design and development of a new type of double horizontal shaft forced stirring engine, and provides some theoretical basis and test data. Through the practical application and verification effect on the site, it is determined that the optimization of the product has been successful.
