產品概況
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。
產品結(jie)構
三筒式烘干機(ji)是通(tong)過對單筒烘干機(ji)的單筒體改為套疊在(zai)一起的三筒，以(yi)縮短烘干機(ji)體的外(wai)形(xing)尺寸。該機(ji)工作時(shi)，物料和熱氣流依(yi)次進入內(nei)至外(wai)筒體，在(zai)機(ji)體Z形(xing)往(wang)復折流后，充(chong)分(fen)利用熱能烘干物料后再卸出。
烘干機筒(tong)(tong)體部分(fen)由三個同軸水平(ping)放置的內、中、外筒(tong)(tong)套疊(die)組成，這就(jiu)使筒(tong)(tong)體的截面(mian)得(de)到充分(fen)的利(li)用。其筒(tong)(tong)體外形總(zong)長度約(yue)為與之(zhi)相當的單筒(tong)(tong)的30-35%。從而大幅度地(di)減(jian)少占地(di)面(mian)積和(he)廠房建筑面(mian)積。
該機(ji)的支承(cheng)裝置，是在外筒(tong)上輪(lun)(lun)帶與托輪(lun)(lun)支承(cheng)，由電機(ji)直(zhi)接帶動(dong)托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶摩擦，使筒(tong)體(ti)轉動(dong)。該機(ji)總體(ti)結構緊湊、合理、簡單，為便于磨(mo)損件(jian)的檢修更換，在中間設計成(cheng)軸向剖分式，用(yong)螺栓固定連接。
工作原理(li)
物(wu)料(liao)由(you)供料(liao)裝(zhuang)置(zhi)進(jin)(jin)(jin)(jin)(jin)入回轉滾(gun)筒(tong)(tong)的(de)(de)內(nei)層(ceng)(ceng),實現順流(liu)(liu)烘(hong)干(gan),物(wu)料(liao)在(zai)(zai)內(nei)層(ceng)(ceng)的(de)(de)抄板下不斷抄起、散落(luo)呈螺(luo)旋行進(jin)(jin)(jin)(jin)(jin)式實現熱交換，物(wu)料(liao)移(yi)動至(zhi)內(nei)層(ceng)(ceng)的(de)(de)另一端(duan)進(jin)(jin)(jin)(jin)(jin)入中(zhong)層(ceng)(ceng)，進(jin)(jin)(jin)(jin)(jin)行逆流(liu)(liu)烘(hong)干(gan)，物(wu)料(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)不斷地(di)被反復揚進(jin)(jin)(jin)(jin)(jin)，呈進(jin)(jin)(jin)(jin)(jin)兩(liang)步退一步的(de)(de)行進(jin)(jin)(jin)(jin)(jin)方式，物(wu)料(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)既充(chong)分吸收內(nei)層(ceng)(ceng)滾(gun)筒(tong)(tong)散發(fa)的(de)(de)熱量，又(you)(you)吸收中(zhong)層(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)(de)熱量，同時(shi)又(you)(you)延長了干(gan)燥(zao)(zao)(zao)(zao)時(shi)間，物(wu)料(liao)在(zai)(zai)此達到(dao)干(gan)燥(zao)(zao)(zao)(zao)狀(zhuang)態。物(wu)料(liao)行至(zhi)中(zhong)層(ceng)(ceng)另一端(duan)而(er)落(luo)入外層(ceng)(ceng)，物(wu)料(liao)在(zai)(zai)外層(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)呈矩形多回路方式行進(jin)(jin)(jin)(jin)(jin)，達到(dao)干(gan)燥(zao)(zao)(zao)(zao)效(xiao)(xiao)果的(de)(de)物(wu)料(liao)在(zai)(zai)熱風作用下快速行進(jin)(jin)(jin)(jin)(jin)排(pai)出滾(gun)筒(tong)(tong)，沒有(you)達到(dao)干(gan)燥(zao)(zao)(zao)(zao)效(xiao)(xiao)果的(de)(de)濕(shi)物(wu)料(liao)因自重而(er)不能(neng)快速行進(jin)(jin)(jin)(jin)(jin)，物(wu)料(liao)在(zai)(zai)此矩形抄板內(nei)進(jin)(jin)(jin)(jin)(jin)行充(chong)分干(gan)燥(zao)(zao)(zao)(zao)，由(you)此完成干(gan)燥(zao)(zao)(zao)(zao)目的(de)(de)。
