產(chan)品(pin)概況
回(hui)轉式三筒(tong)(tong)烘(hong)(hong)干(gan)(gan)機改進(jin)原單(dan)筒(tong)(tong)烘(hong)(hong)干(gan)(gan)機內部結構,增加(jia)入機前濕(shi)(shi)料的預(yu)烘(hong)(hong)干(gan)(gan)和延長濕(shi)(shi)料在(zai)機內烘(hong)(hong)干(gan)(gan)時間,再加(jia)上密封、保溫以及合(he)理的配(pei)套措施,使烘(hong)(hong)干(gan)(gan)機生產(chan)能力與(yu)原單(dan)筒(tong)(tong)式烘(hong)(hong)干(gan)(gan)機相比(bi),提高48-80%,單(dan)位容積蒸發(fa)強度可達(da)120-180kg/m3,標準煤(mei)耗僅為6-8kg/t。其(qi)技術先進(jin)、運行(xing)參數合(he)理,操作(zuo)簡單(dan)可行(xing),廣(guang)泛應用于各個行(xing)業的礦渣(zha)、粘土、煤(mei)。
產品(pin)結構
三筒(tong)烘(hong)干機是通過(guo)對單筒(tong)烘(hong)干機的(de)單筒(tong)體改(gai)為套(tao)疊在(zai)一(yi)起的(de)三筒(tong),以縮短烘(hong)干機體的(de)外(wai)(wai)形(xing)尺寸。該(gai)機工作時,物料(liao)和熱(re)(re)氣流依次進入(ru)內至外(wai)(wai)筒(tong)體,在(zai)機體Z形(xing)往復折(zhe)流后(hou),充分利用熱(re)(re)能烘(hong)干物料(liao)后(hou)再卸(xie)出。
烘干機筒體(ti)部分(fen)由三個同軸水平放(fang)置的內(nei)、中、外筒套疊(die)組成,這就使筒體(ti)的截面(mian)(mian)得到(dao)充分(fen)的利用。其筒體(ti)外形總長度約為與之相(xiang)當的單(dan)筒的30-35%。從而大幅度地減少占地面(mian)(mian)積和廠房建(jian)筑面(mian)(mian)積。
該(gai)機(ji)的支承裝置,是在(zai)外筒上(shang)輪帶與托輪支承,由電機(ji)直接(jie)帶動托輪。通過托輪與輪帶摩擦,使筒體(ti)轉動。該(gai)機(ji)總體(ti)結構緊湊、合理(li)、簡單(dan),為便于磨損件的檢修更換,在(zai)中間(jian)設(she)計成軸向剖分式,用螺栓固定連接(jie)。
工作原理
