產(chan)品概況
回(hui)轉式(shi)三筒(tong)烘(hong)干機(ji)(ji)改進原單(dan)筒(tong)烘(hong)干機(ji)(ji)內(nei)(nei)部(bu)結(jie)構，增加(jia)入機(ji)(ji)前濕料的預烘(hong)干和延長濕料在(zai)機(ji)(ji)內(nei)(nei)烘(hong)干時間，再加(jia)上密封(feng)、保溫以及合理的配套措施(shi)，使烘(hong)干機(ji)(ji)生產(chan)能力與原單(dan)筒(tong)式(shi)烘(hong)干機(ji)(ji)相比，提高48-80%，單(dan)位容積蒸發強度可(ke)達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進、運(yun)行(xing)參數(shu)合理，操作簡單(dan)可(ke)行(xing)，廣泛應(ying)用于各個行(xing)業的礦渣、粘土、煤。
產品結(jie)構
三筒(tong)烘干機是通過(guo)對單(dan)筒(tong)烘干機的單(dan)筒(tong)體改為(wei)套疊在一起的三筒(tong)，以縮短烘干機體的外形尺寸(cun)。該(gai)機工作時，物(wu)料(liao)和熱(re)氣流依次(ci)進入內至(zhi)外筒(tong)體，在機體Z形往復折流后，充分(fen)利用熱(re)能烘干物(wu)料(liao)后再(zai)卸出(chu)。
烘干機筒體部分(fen)由三(san)個同(tong)軸(zhou)水平放置(zhi)的內、中、外筒套疊組成，這就使筒體的截面(mian)(mian)(mian)得到(dao)充(chong)分(fen)的利用。其(qi)筒體外形總長度約為與之相當的單筒的30-35%。從而(er)大(da)幅度地(di)減少(shao)占(zhan)地(di)面(mian)(mian)(mian)積(ji)和廠房建筑面(mian)(mian)(mian)積(ji)。
該機(ji)的(de)(de)支承(cheng)裝置，是(shi)在外(wai)筒上輪(lun)(lun)帶與托輪(lun)(lun)支承(cheng)，由電機(ji)直接(jie)帶動托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶摩擦，使筒體轉(zhuan)動。該機(ji)總體結構緊湊、合(he)理(li)、簡單，為便于磨損件的(de)(de)檢修(xiu)更換(huan)，在中間設(she)計成(cheng)軸向剖分式，用螺栓固定連(lian)接(jie)。
