直線振動篩設計說明書.doc

I摘要振動篩的研究不斷地向著標準化、系列化、通用化發(fā)展，并引入現(xiàn)代化設計手段，采用新材料、新技術、新工藝，其目的在于不斷擴大篩機應用領域，滿足國民經(jīng)濟建設發(fā)展的需要，并擔當對外出口的任務。本文所設計的振動篩的篩分物料為球磨機產(chǎn)品。該產(chǎn)品的大小不是很平均，為了做出更符合要求的物料就需要用振動篩來將球磨機產(chǎn)品進一步細分，將不符合要求的物料重新用球磨機磨小。經(jīng)過這樣的反復處理最終將物料全部做成符合要求的產(chǎn)品。本課題的振動篩為自同步雙振動電機驅(qū)動的，其特點是結構簡單、安裝方便、成本低、容易操作及維護等。其篩箱為板梁鉚焊組合結構，由主副側板、管梁、入料擋板、出料板、篩板等組成，側板選用低合金壓力容器鋼板，強度高、可焊性好，周邊折彎，并在振動方向及沿縱向連接多根角鋼，使側板剛度大大增強，有利于強度的提高和噪音的降低。管梁由法蘭盤、無縫鋼管、加強槽鋼等組成，重量輕、強度大，便于制造安裝，具有互換性。加強槽鋼上有T形孔，使用T形螺栓，便于篩板的安裝維護，消除U形螺栓對管梁的磨損。工作原理：兩臺振動電機的型號相同，可以產(chǎn)生一種組合的直線振動。這種振動可以使輸送槽體中的物料運動，并與篩面發(fā)生碰撞，使小于篩孔的物料透過，從而實現(xiàn)物料的幾何分級，實現(xiàn)篩分?？傮w方案為：采用普通篩分法，振動形式為共振，運動軌跡為直線運動，激振方式為慣性式，隔振方式為一級隔振，隔振彈簧為金屬螺旋式隔振彈簧。關鍵詞：振動篩；篩箱；振動電機IIAbstractTheshakerresearchunceasinglytothestandardization,theseriation,theuniversalizeddevelopment,andtheintroductionmodernizationdesignmethod,usesthenewmaterial,thenewtechnology,thenewcraft,itsgoalliesinunceasinglyexpandsthesievemachineapplicationdomain,satisfiesnationaleconomyconstructiontheneedtodevelop,andtakesontheforeignexportationtheduty.Finallycompletelymakesaftersuchrepeatedlyprocessingthematerialltalliestherequestproduct.Thistopicshakerforself-synchronizingpairvibrationmotor-driven,Itscharacteristicisthestructuresimple,theinstallsconvenient,thecostlow,iseasytooperateandthemaintenanceandsoon.Itsievestheboxisboardcrossbeamrivetinghitchweldsbuilt-upsection,Byhostvice-sidebar,Hollowbeam,Entersthematerialbackplate,Leavesmaterialboard,Sievesboardandsooncomposition,Thesidebarselectsthelow-alloypressurevesselsteelplate,Theintensityishigh,Theweldabilityisgood,Peripheralkneebend,Andinthevibrationdirectionandalonglongitudinalconnectsthemulti-rootsanglesteel,Causesthesidebarrigiditybigenhancement,Isadvantageoustotheintensityenhancementandnoisereducing.Hollowbeambyflangeplate,Seamlesssteelpipe,Strengthenscompositionandsoonchannelsteel,Theweightlight,theintensityisbig,isadvantageousforthemanufactureinstallment,Hastheinterchangeability.StrengthensinthechannelsteeltohavetheTshapehole,UsestheTshapebolt,Isadvantageousforscreenboardinstallsthemaintenance,EliminatestheUshapebolttothehollowbeamattrition.Principleofwork:Twovibratetheelectricalmachinerythemodeltobesame,Mayhaveonekindofcombinationstraight-lineoscillation.Thiskindofvibrationmaycauseinthetransportationtroughbodythematerialmovement,Andhasthecollisionwiththescreeningsurface,Andhasthecollisionwiththescreeningsurface,Thusrealizationmaterialgeometrygraduation,Realizationscreening.Theoverallplanis:Usestheordinaryscreeninglaw,Thevibrationformforresonates,Thepathisthetranslation,Stirsupthestrengthvibrationthewayistheinertiatype,Thevibrationisolationwayislevelofvibrationisolations,Thevibrationisolationspringisthemetalscrewtypevibrationisolationspring。Keywords:thevibrationscreen；theboxscreen；thevibrationelectricmachineryIII目錄摘要.IAbstract.II第1章概述.11.1國內(nèi)外現(xiàn)狀.11.2振動機械的用途和分類.11.2.1振動機械的組成.21.2.2振動機械的特點.21.2.4振動機械的分類.3第2章主要問題及解決方案.52.1振動篩降噪措施.52.2常見故障及處理措施.52.2.1篩分時篩子不下料或下料不暢.52.2.2篩框斷裂根.52.2.3軸承過熱.52.2.4篩分的分級(根據(jù)篩分的目的).6第3章直線振動細篩的結構、工作原理及總體方案的比較確定.73.1結構及工作原理.73.2直線型振動細篩的特點.73.3各類篩分方法的比較確定.83.3.1普通篩分方法.83.3.2概率篩分方法.93.3.3等厚篩分法.93.3.4概率等厚篩分法.103.3.5篩分方法的確定.103.4振動形式的確定.103.4.1非共振篩.103.4.2共振篩.103.5運動軌跡的確定.103.5.1圓運動軌跡.103.5.2直線運動軌跡.113.6激振方式的比較.113.6.1彈性連桿式.113.6.2電磁式.11IV3.6.3慣性式.123.6.4激振方式的確定.12第4章其它零部件的選擇.134.1隔振系統(tǒng)的選擇.134.2篩箱及篩面.134.2.1篩箱.134.2.2篩面的比較選擇.144.2.3篩面的壓緊裝置.154.3支撐裝置的選擇.15第5章各部分設計計算.175.1運動學參數(shù)
