產品概況
回轉式(shi)三筒烘(hong)(hong)(hong)干(gan)機(ji)改進原單筒烘(hong)(hong)(hong)干(gan)機(ji)內部結構(gou)，增(zeng)加入機(ji)前濕料的預烘(hong)(hong)(hong)干(gan)和延(yan)長濕料在(zai)機(ji)內烘(hong)(hong)(hong)干(gan)時(shi)間，再加上(shang)密(mi)封、保溫以(yi)及合理的配套(tao)措施，使(shi)烘(hong)(hong)(hong)干(gan)機(ji)生產(chan)能力(li)與原單筒式(shi)烘(hong)(hong)(hong)干(gan)機(ji)相比，提(ti)高48-80%，單位容(rong)積蒸發強度可達(da)120-180kg/m3，標(biao)準煤耗僅為(wei)6-8kg/t。其技術先進、運行(xing)參數合理，操作簡單可行(xing)，廣泛應用于(yu)各個(ge)行(xing)業的礦渣、粘土、煤。
產品結(jie)構
三筒烘干(gan)(gan)機是通過對單(dan)(dan)筒烘干(gan)(gan)機的(de)單(dan)(dan)筒體(ti)改為套疊在(zai)一起的(de)三筒，以(yi)縮短(duan)烘干(gan)(gan)機體(ti)的(de)外形尺(chi)寸。該機工作時(shi)，物(wu)料(liao)和熱氣流依(yi)次(ci)進入內至外筒體(ti)，在(zai)機體(ti)Z形往復折流后，充分利用熱能烘干(gan)(gan)物(wu)料(liao)后再卸(xie)出。
烘干機筒(tong)體(ti)部分由三個同軸水平(ping)放置(zhi)的內、中、外(wai)筒(tong)套疊(die)組成，這就使筒(tong)體(ti)的截面(mian)(mian)得到充分的利(li)用。其筒(tong)體(ti)外(wai)形總長度(du)約為(wei)與(yu)之(zhi)相當的單筒(tong)的30-35%。從(cong)而大幅度(du)地減少占地面(mian)(mian)積和廠房建筑面(mian)(mian)積。
該(gai)機(ji)(ji)的支承裝置，是在外筒上輪(lun)帶與托輪(lun)支承，由電機(ji)(ji)直接(jie)帶動托輪(lun)。通過托輪(lun)與輪(lun)帶摩(mo)擦，使筒體轉(zhuan)動。該(gai)機(ji)(ji)總體結構緊(jin)湊、合理、簡(jian)單，為便于(yu)磨損(sun)件的檢修更換，在中(zhong)間設計(ji)成(cheng)軸向剖分式，用螺(luo)栓固(gu)定連接(jie)。
