產(chan)品(pin)概(gai)況
回轉(zhuan)式(shi)三筒(tong)烘(hong)(hong)干機改(gai)進原(yuan)單(dan)(dan)筒(tong)烘(hong)(hong)干機內部結構，增加入(ru)機前濕料的(de)預烘(hong)(hong)干和延(yan)長濕料在機內烘(hong)(hong)干時間(jian)，再加上密封(feng)、保溫(wen)以及合理的(de)配套措施，使烘(hong)(hong)干機生產能力(li)與原(yuan)單(dan)(dan)筒(tong)式(shi)烘(hong)(hong)干機相比，提高48-80%，單(dan)(dan)位容積(ji)蒸發強度可達120-180kg/m3，標準煤(mei)耗僅為6-8kg/t。其(qi)技術先進、運行參數合理，操作簡單(dan)(dan)可行，廣泛應用(yong)于各個行業(ye)的(de)礦渣、粘土、煤(mei)。
產(chan)品結構(gou)
三筒(tong)烘(hong)(hong)干(gan)機(ji)是通(tong)過對單筒(tong)烘(hong)(hong)干(gan)機(ji)的(de)(de)(de)單筒(tong)體改為(wei)套疊在一(yi)起的(de)(de)(de)三筒(tong)，以(yi)縮(suo)短烘(hong)(hong)干(gan)機(ji)體的(de)(de)(de)外(wai)形(xing)尺寸。該機(ji)工作時，物料和熱(re)氣(qi)流依(yi)次進入內至(zhi)外(wai)筒(tong)體，在機(ji)體Z形(xing)往復折流后(hou)(hou)，充(chong)分利用熱(re)能(neng)烘(hong)(hong)干(gan)物料后(hou)(hou)再(zai)卸(xie)出(chu)。
烘干機(ji)筒(tong)體部(bu)分由三個同軸水平放(fang)置的(de)內(nei)、中(zhong)、外(wai)筒(tong)套疊(die)組(zu)成，這就使筒(tong)體的(de)截面(mian)得到(dao)充分的(de)利用。其筒(tong)體外(wai)形總長度(du)約為(wei)與之相當(dang)的(de)單筒(tong)的(de)30-35%。從而大幅(fu)度(du)地減少占地面(mian)積(ji)和廠房建筑(zhu)面(mian)積(ji)。
該(gai)機(ji)的支承裝置(zhi)，是在外筒上(shang)輪帶與托輪支承，由電機(ji)直接帶動托輪。通(tong)過(guo)托輪與輪帶摩擦，使筒體(ti)轉動。該(gai)機(ji)總體(ti)結(jie)構緊湊(cou)、合理、簡單，為(wei)便于磨損(sun)件的檢修更(geng)換，在中間設(she)計成軸向剖(pou)分式，用螺栓固定連(lian)接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)(liao)由(you)供(gong)料(liao)(liao)(liao)裝(zhuang)置進(jin)(jin)入回轉滾筒(tong)(tong)的(de)內(nei)層(ceng)(ceng)(ceng),實(shi)現順流烘干(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)的(de)抄(chao)板下(xia)不(bu)斷抄(chao)起、散(san)落(luo)呈(cheng)(cheng)螺旋行進(jin)(jin)式實(shi)現熱交換，物(wu)(wu)(wu)料(liao)(liao)(liao)移動至(zhi)內(nei)層(ceng)(ceng)(ceng)的(de)另一端進(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)行逆流烘干(gan)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)不(bu)斷地被反復揚(yang)進(jin)(jin)，呈(cheng)(cheng)進(jin)(jin)兩步退一步的(de)行進(jin)(jin)方(fang)式，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)既充分吸(xi)收內(nei)層(ceng)(ceng)(ceng)滾筒(tong)(tong)散(san)發的(de)熱量，又吸(xi)收中(zhong)層(ceng)(ceng)(ceng)滾筒(tong)(tong)的(de)熱量，同時(shi)又延長了干(gan)燥時(shi)間(jian)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此達到(dao)干(gan)燥狀(zhuang)態。物(wu)(wu)(wu)料(liao)(liao)(liao)行至(zhi)中(zhong)層(ceng)(ceng)(ceng)另一端而(er)落(luo)入外(wai)層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)(ceng)滾筒(tong)(tong)內(nei)呈(cheng)(cheng)矩形多回路方(fang)式行進(jin)(jin)，達到(dao)干(gan)燥效(xiao)果(guo)的(de)物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)熱風作用下(xia)快速(su)行進(jin)(jin)排出滾筒(tong)(tong)，沒有達到(dao)干(gan)燥效(xiao)果(guo)的(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)因自重而(er)不(bu)能快速(su)行進(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此矩形抄(chao)板內(nei)進(jin)(jin)行充分干(gan)燥，由(you)此完成干(gan)燥目的(de)。
