I摘要振動(dòng)篩的研究不斷地向著標(biāo)準(zhǔn)化、系列化、通用化發(fā)展，并引入現(xiàn)代化設(shè)計(jì)手段，采用新材料、新技術(shù)、新工藝，其目的在于不斷擴(kuò)大篩機(jī)應(yīng)用領(lǐng)域，滿足國民經(jīng)濟(jì)建設(shè)發(fā)展的需要，并擔(dān)當(dāng)對(duì)外出口的任務(wù)。本文所設(shè)計(jì)的振動(dòng)篩的篩分物料為球磨機(jī)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(dòng)篩來將球磨機(jī)產(chǎn)品進(jìn)一步細(xì)分，將不符合要求的物料重新用球磨機(jī)磨小。經(jīng)過這樣的反復(fù)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(dòng)篩為自同步雙振動(dòng)電機(jī)驅(qū)動(dòng)的，其特點(diǎn)是結(jié)構(gòu)簡單、安裝方便、成本低、容易操作及維護(hù)等。其篩箱為板梁鉚焊組合結(jié)構(gòu)，由主副側(cè)板、管梁、入料擋板、出料板、篩板等組成，側(cè)板選用低合金壓力容器鋼板，強(qiáng)度高、可焊性好，周邊折彎，并在振動(dòng)方向及沿縱向連接多根角鋼，使側(cè)板剛度大大增強(qiáng)，有利于強(qiáng)度的提高和噪音的降低。管梁由法蘭盤、無縫鋼管、加強(qiáng)槽鋼等組成，重量輕、強(qiáng)度大，便于制造安裝，具有互換性。加強(qiáng)槽鋼上有T形孔，使用T形螺栓，便于篩板的安裝維護(hù)，消除U形螺栓對(duì)管梁的磨損。工作原理：兩臺(tái)振動(dòng)電機(jī)的型號(hào)相同，可以產(chǎn)生一種組合的直線振動(dòng)。這種振動(dòng)可以使輸送槽體中的物料運(yùn)動(dòng)，并與篩面發(fā)生碰撞，使小于篩孔的物料透過，從而實(shí)現(xiàn)物料的幾何分級(jí)，實(shí)現(xiàn)篩分。總體方案為：采用普通篩分法，振動(dòng)形式為共振，運(yùn)動(dòng)軌跡為直線運(yùn)動(dòng)，激振方式為慣性式，隔振方式為一級(jí)隔振，隔振彈簧為金屬螺旋式隔振彈簧。關(guān)鍵詞：振動(dòng)篩；篩箱；振動(dòng)電機(jī)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(dòng)機(jī)械的用途和分類.11.2.1振動(dòng)機(jī)械的組成.21.2.2振動(dòng)機(jī)械的特點(diǎn).21.2.4振動(dòng)機(jī)械的分類.3第2章主要問題及解決方案.52.1振動(dòng)篩降噪措施.52.2常見故障及處理措施.52.2.1篩分時(shí)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(jí)(根據(jù)篩分的目的).6第3章直線振動(dòng)細(xì)篩的結(jié)構(gòu)、工作原理及總體方案的比較確定.73.1結(jié)構(gòu)及工作原理.73.2直線型振動(dòng)細(xì)篩的特點(diǎn).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(dòng)形式的確定.103.4.1非共振篩.103.4.2共振篩.103.5運(yùn)動(dòng)軌跡的確定.103.5.1圓運(yùn)動(dòng)軌跡.103.5.2直線運(yùn)動(dòng)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(shè)計(jì)計(jì)算.175.1運(yùn)動(dòng)學(xué)參數(shù)
