產品(pin)概況
回轉式三筒(tong)(tong)烘(hong)干(gan)(gan)機(ji)改進原單(dan)(dan)筒(tong)(tong)烘(hong)干(gan)(gan)機(ji)內部結(jie)構,增加(jia)(jia)入機(ji)前濕料的(de)預(yu)烘(hong)干(gan)(gan)和(he)延(yan)長濕料在機(ji)內烘(hong)干(gan)(gan)時間,再加(jia)(jia)上密封(feng)、保溫以及合理(li)(li)的(de)配套措施,使烘(hong)干(gan)(gan)機(ji)生(sheng)產(chan)能(neng)力與(yu)原單(dan)(dan)筒(tong)(tong)式烘(hong)干(gan)(gan)機(ji)相比(bi),提高48-80%,單(dan)(dan)位(wei)容積(ji)蒸發強度可達(da)120-180kg/m3,標準(zhun)煤(mei)耗僅為6-8kg/t。其技術先(xian)進、運行(xing)(xing)參數合理(li)(li),操作簡單(dan)(dan)可行(xing)(xing),廣泛應用于(yu)各個行(xing)(xing)業(ye)的(de)礦渣、粘土、煤(mei)。
產品結構
三筒(tong)(tong)烘干(gan)機是通過對單(dan)筒(tong)(tong)烘干(gan)機的單(dan)筒(tong)(tong)體改為套疊在(zai)一起(qi)的三筒(tong)(tong),以(yi)縮短烘干(gan)機體的外形(xing)尺寸。該機工作時,物料(liao)和熱(re)氣流依次進入(ru)內至外筒(tong)(tong)體,在(zai)機體Z形(xing)往(wang)復折流后,充分利用(yong)熱(re)能(neng)烘干(gan)物料(liao)后再卸出。
烘干機筒體(ti)(ti)部分由三個同(tong)軸(zhou)水(shui)平放置(zhi)的(de)(de)(de)內、中、外筒套疊(die)組成,這就使筒體(ti)(ti)的(de)(de)(de)截面得到充分的(de)(de)(de)利用。其筒體(ti)(ti)外形總長度約為(wei)與之相(xiang)當的(de)(de)(de)單筒的(de)(de)(de)30-35%。從而(er)大幅度地減少(shao)占地面積和廠房建筑(zhu)面積。
該(gai)機的支(zhi)承裝置,是在(zai)外筒(tong)上輪(lun)帶與托輪(lun)支(zhi)承,由電機直接帶動托輪(lun)。通(tong)過托輪(lun)與輪(lun)帶摩擦,使筒(tong)體(ti)轉動。該(gai)機總體(ti)結構緊(jin)湊、合(he)理、簡單,為(wei)便于磨損件的檢修更換,在(zai)中間設(she)計成軸向剖分式(shi),用螺栓固定連(lian)接。
