    如何安裝維護自動上料攪拌機

    作者:http://www.kenguscpas.com 時間:2021-02-15

    拌和設備的用處、分類在挑選拌和容器時,應根據出產規模(即物料處理量)、拌和操作意圖和物料特性確認拌和容器的形狀和尺寸,在確認拌和容器的容積時應合理挑選裝料系數,盡量進步設備的利用率。假如沒有特殊需要,釜體一般宜選用最常用的立式圓筒形容器,并挑選適合的筒體高徑比(或容器裝液高徑比)。若有傳熱要求,則釜體外須設置夾套結構。夾套品種有全體夾套、螺旋擋板夾套、半管夾套、蜂窩夾套,傳熱效果依次進步但制作本錢也相應增加。   Useandclassificationofmixingequipmentwhenselectingmixingcontainers,theshapeandsizeofmixingcontainersshouldbeconfirmedaccordingtotheproductionscale(i.e.materialhandlingcapacity),mixingoperationintentionandmaterialcharacteristics.Whenconfirmingthevolumeofmixingcontainers,thechargingcoefficientshouldbereasonablyselectedtoimprovetheutilizationrateofequipmentasfaraspossible.Ifthereisnospecialneed,themostcommonlyusedverticalcylindricalvesselshouldbeselectedforthekettlebody,andthesuitableheightdiameterratio(orliquidloadingheightdiameterratio)shouldbeselected.Ifheattransferisrequired,jacketstructureshouldbesetoutsidethekettle.Thereareallkindsofjacket,spiralbafflejacket,halfpipejacketandhoneycombjacket.Theheattransfereffectisimprovedinturn,buttheproductioncostisalsoincreasedcorrespondingly.
        當拌和釜臥式放置時,大多進行半釜操作。因此臥式釜與立式釜相比有更多的氣-液觸摸面積,因此臥式釜常用于氣-液傳質進程,如氣-液吸收或從高粘度液體中脫除少數易揮發物質,另一方面,臥式釜的料層較淺,有利于拌和器將粉末攪動,并可借拌和器的高速反轉使粉體拋揚起來,使粉體在瞬間失重狀態下進行混合。    Whenthemixingkettleisplacedhorizontally,halfkettleoperationismostlycarriedout.Therefore,thehorizontalkettlehasmoregas-liquidcontactareathantheverticalkettle,sothehorizontalkettleisoftenusedingas-liquidmasstransferprocess,suchasgas-liquidabsorptionorremovalofafewvolatilesubstancesfromhighviscosityliquid.Ontheotherhand,theshallowmateriallayerofthehorizontalkettleisconducivetostirringthepowderbythemixer,andthepowdercanbethrownupbythehigh-speedreversalofthemixer,sothatthepowdercanloseweightinstantlyThemixturewascarriedoutunderdifferentconditions.
        拌和容器的材料要滿足出產工藝的要求,例如耐壓、耐溫、耐介質腐蝕,以及確保產品清潔等。因為材料的不同,拌和容器的制作工藝、結構也有所不同,因此可分為鋼制拌和設備、搪玻璃拌和設備和帶面料的拌和設備等。裝面料的意圖是為了耐蝕或保護產品的清潔,面料的品種許多,首要有不銹鋼、鋁、鈦、鉛、鎳、鋯、耐酸瓷磚、輝綠巖板、橡膠等。    Thematerialofmixingcontainershallmeettherequirementsofproductionprocess,suchaspressureresistance,temperatureresistance,mediumcorrosionresistance,andproductcleaning.Becauseofthedifferentmaterials,themanufacturingprocessandstructureofmixingcontainerarealsodifferent,soitcanbedividedintosteelmixingequipment,glasslinedmixingequipmentandmixingequipmentwithfabric.Therearemanykindsoffabrics,includingstainlesssteel,aluminum,titanium,lead,nickel,zirconium,acidresistantceramictile,diabaseboard,rubber,etc.
        自動上料攪拌機拌和設備一般由容器部分、傳動設備、換熱設備、拌和設備、軸封設備組成。在工業出產中的應用范圍很廣,尤其是化學工業中,許多的化工出產都或多或少地應用著拌和操作。拌和設備在許多場合是作為反應器來應用的。例如在三大合成材料的出產中,以拌和設備作為反應器的約占反應器總數的90%。    Themixingequipmentofautomaticfeedingmixerisgenerallycomposedofcontainer,transmissionequipment,heatexchangeequipment,mixingequipmentandshaftsealequipment.Itiswidelyusedinindustrialproduction,especiallyinchemicalindustry,manychemicalproductsaremoreorlessusedinmixingoperation.Mixingequipmentisusedasreactorinmanyoccasions.Forexample,intheproductionofthreemajorsyntheticmaterials,mixingequipmentasareactoraccountsforabout90%ofthetotalnumberofreactors.
        機器的保護保養是一項極其重要的經常性的作業,它應與極其的操作和檢修等密切配合,應有專職人員進行值勤查看
