產品概況(kuang)
回(hui)轉(zhuan)式三筒烘(hong)干(gan)(gan)機(ji)(ji)(ji)(ji)改(gai)進原(yuan)單(dan)(dan)(dan)筒烘(hong)干(gan)(gan)機(ji)(ji)(ji)(ji)內部結構,增(zeng)加入(ru)機(ji)(ji)(ji)(ji)前濕料的預烘(hong)干(gan)(gan)和延(yan)長濕料在機(ji)(ji)(ji)(ji)內烘(hong)干(gan)(gan)時(shi)間,再(zai)加上密封、保溫(wen)以及(ji)合(he)理的配套(tao)措(cuo)施,使烘(hong)干(gan)(gan)機(ji)(ji)(ji)(ji)生(sheng)產能(neng)力與原(yuan)單(dan)(dan)(dan)筒式烘(hong)干(gan)(gan)機(ji)(ji)(ji)(ji)相比,提高48-80%,單(dan)(dan)(dan)位容積(ji)蒸發強度可達120-180kg/m3,標準煤耗(hao)僅為6-8kg/t。其技術先進、運行(xing)參數(shu)合(he)理,操作簡單(dan)(dan)(dan)可行(xing),廣(guang)泛(fan)應用于各個(ge)行(xing)業的礦渣、粘土、煤。
產品結構
三筒(tong)烘干機是通過對單筒(tong)烘干機的(de)單筒(tong)體(ti)改為套疊(die)在一起的(de)三筒(tong),以縮短烘干機體(ti)的(de)外形尺寸。該機工作時,物料(liao)和熱氣流依次進入(ru)內至外筒(tong)體(ti),在機體(ti)Z形往(wang)復折流后(hou),充分(fen)利用熱能烘干物料(liao)后(hou)再卸(xie)出(chu)。
烘干機筒(tong)體(ti)部(bu)分由(you)三個同軸水平放置的內、中、外(wai)筒(tong)套(tao)疊組(zu)成,這就使(shi)筒(tong)體(ti)的截面得到(dao)充分的利(li)用。其筒(tong)體(ti)外(wai)形總長度(du)約為(wei)與之相當的單筒(tong)的30-35%。從而大(da)幅度(du)地減(jian)少占地面積(ji)和廠房建筑面積(ji)。
該機(ji)的支承(cheng)裝(zhuang)置,是在外(wai)筒上輪(lun)帶(dai)與(yu)托(tuo)輪(lun)支承(cheng),由(you)電機(ji)直接(jie)(jie)帶(dai)動托(tuo)輪(lun)。通過(guo)托(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩(mo)擦,使(shi)筒體轉動。該機(ji)總體結構緊(jin)湊、合(he)理(li)、簡單(dan),為便于磨損件(jian)的檢修更換,在中間設計成軸向(xiang)剖分式,用(yong)螺(luo)栓固定連接(jie)(jie)。
