產品概況(kuang)
回轉式三筒烘干機改進原單筒烘干機內部結構，增加入機前濕料的預烘干和延長濕料在機內烘干時間，再加上密封、保溫以及合理的配套措施，使烘干機生產能力與原單筒式烘干機相比，提高48-80%，單位容積蒸發強度可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進、運行參數合理，操作簡單可行，廣泛應用于各個行業的礦渣、粘土、煤。
產(chan)品結構
三(san)筒(tong)(tong)式烘(hong)干機(ji)是通過對單筒(tong)(tong)烘(hong)干機(ji)的單筒(tong)(tong)體(ti)改(gai)為套疊在(zai)一起的三(san)筒(tong)(tong)，以縮短烘(hong)干機(ji)體(ti)的外形尺寸。該機(ji)工作時(shi)，物(wu)料和熱氣流(liu)依次進入內至外筒(tong)(tong)體(ti)，在(zai)機(ji)體(ti)Z形往復折(zhe)流(liu)后(hou)，充分利(li)用(yong)熱能(neng)烘(hong)干物(wu)料后(hou)再(zai)卸(xie)出。
烘(hong)干機筒體部分由(you)三個同軸水平放置的內(nei)、中、外(wai)筒套疊(die)組成，這就使筒體的截(jie)面得(de)到(dao)充分的利用(yong)。其筒體外(wai)形總長度約為與之相當的單筒的30-35%。從而大(da)幅度地減少(shao)占地面積(ji)(ji)和廠房建(jian)筑面積(ji)(ji)。
該(gai)機(ji)的支承裝置，是在(zai)外筒(tong)上輪帶與托(tuo)輪支承，由電(dian)機(ji)直(zhi)接帶動托(tuo)輪。通(tong)過托(tuo)輪與輪帶摩擦，使筒(tong)體轉(zhuan)動。該(gai)機(ji)總體結構緊湊(cou)、合(he)理、簡(jian)單，為便于磨損件的檢(jian)修更換，在(zai)中間設(she)計成軸向剖分式，用螺栓(shuan)固定連接。
工作原理(li)
物(wu)(wu)(wu)(wu)料(liao)(liao)由(you)供料(liao)(liao)裝置(zhi)進(jin)(jin)(jin)入回(hui)轉滾筒(tong)(tong)(tong)的(de)內(nei)層,實現(xian)順(shun)流烘干(gan)(gan)(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在內(nei)層的(de)抄板下不(bu)(bu)斷抄起、散落呈螺旋行(xing)進(jin)(jin)(jin)式(shi)實現(xian)熱(re)交換，物(wu)(wu)(wu)(wu)料(liao)(liao)移動至(zhi)內(nei)層的(de)另(ling)一端進(jin)(jin)(jin)入中(zhong)(zhong)層，進(jin)(jin)(jin)行(xing)逆流烘干(gan)(gan)(gan)(gan)，物(wu)(wu)(wu)(wu)料(liao)(liao)在中(zhong)(zhong)層不(bu)(bu)斷地被反復揚進(jin)(jin)(jin)，呈進(jin)(jin)(jin)兩步(bu)退一步(bu)的(de)行(xing)進(jin)(jin)(jin)方式(shi)，物(wu)(wu)(wu)(wu)料(liao)(liao)在中(zhong)(zhong)層既(ji)充(chong)分吸收內(nei)層滾筒(tong)(tong)(tong)散發的(de)熱(re)量，又吸收中(zhong)(zhong)層滾筒(tong)(tong)(tong)的(de)熱(re)量，同時又延(yan)長了干(gan)(gan)(gan)(gan)燥(zao)時間，物(wu)(wu)(wu)(wu)料(liao)(liao)在此(ci)(ci)達(da)到干(gan)(gan)(gan)(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)至(zhi)中(zhong)(zhong)層另(ling)一端而落入外層，物(wu)(wu)(wu)(wu)料(liao)(liao)在外層滾筒(tong)(tong)(tong)內(nei)呈矩形(xing)多回(hui)路(lu)方式(shi)行(xing)進(jin)(jin)(jin)，達(da)到干(gan)(gan)(gan)(gan)燥(zao)效果的(de)物(wu)(wu)(wu)(wu)料(liao)(liao)在熱(re)風(feng)作用下快速行(xing)進(jin)(jin)(jin)排出滾筒(tong)(tong)(tong)，沒有達(da)到干(gan)(gan)(gan)(gan)燥(zao)效果的(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)因自重(zhong)而不(bu)(bu)能快速行(xing)進(jin)(jin)(jin)，物(wu)(wu)(wu)(wu)料(liao)(liao)在此(ci)(ci)矩形(xing)抄板內(nei)進(jin)(jin)(jin)行(xing)充(chong)分干(gan)(gan)(gan)(gan)燥(zao)，由(you)此(ci)(ci)完成干(gan)(gan)(gan)(gan)燥(zao)目的(de)。
