產品結構
大型三筒烘干機是通過對單筒烘干機的單筒體改為套疊在一起的三筒,以縮短烘干機體的外形尺寸。該機工作時,物料和熱氣流依次進入內至外筒體,在機體Z形往復折流后,充分利用熱能烘干物料后再卸出。
烘(hong)干機筒(tong)(tong)體(ti)部分由三個同軸水平放(fang)置(zhi)的(de)內、中、外筒(tong)(tong)套疊組成,這(zhe)就使筒(tong)(tong)體(ti)的(de)截面(mian)得到充分的(de)利用(yong)。其筒(tong)(tong)體(ti)外形總(zong)長度約為與之(zhi)相當(dang)的(de)單筒(tong)(tong)的(de)30-35%。從(cong)而(er)大幅度地減(jian)少占地面(mian)積和(he)廠(chang)房建筑面(mian)積。
該(gai)機(ji)的支承裝置,是(shi)在(zai)外筒(tong)上(shang)輪(lun)帶(dai)與托輪(lun)支承,由電機(ji)直(zhi)接(jie)帶(dai)動(dong)托輪(lun)。通(tong)過托輪(lun)與輪(lun)帶(dai)摩擦,使筒(tong)體轉動(dong)。該(gai)機(ji)總體結構緊湊、合理、簡單,為(wei)便于磨損件的檢修更換(huan),在(zai)中間設計成(cheng)軸向剖分式,用螺栓固定連(lian)接(jie)。
工作原理
物料(liao)(liao)(liao)(liao)由(you)(you)供料(liao)(liao)(liao)(liao)裝(zhuang)置(zhi)進(jin)(jin)入(ru)(ru)回(hui)(hui)轉滾(gun)筒(tong)的(de)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng),實現(xian)順(shun)流烘干(gan)(gan)(gan)(gan),物料(liao)(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)抄板下不斷(duan)抄起、散落呈(cheng)螺旋行(xing)進(jin)(jin)式(shi)(shi)實現(xian)熱交換(huan),物料(liao)(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)另一端(duan)進(jin)(jin)入(ru)(ru)中層(ceng)(ceng)(ceng)(ceng)(ceng),進(jin)(jin)行(xing)逆流烘干(gan)(gan)(gan)(gan),物料(liao)(liao)(liao)(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)(ceng)不斷(duan)地(di)被反復揚進(jin)(jin),呈(cheng)進(jin)(jin)兩步(bu)退一步(bu)的(de)行(xing)進(jin)(jin)方(fang)式(shi)(shi),物料(liao)(liao)(liao)(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)(ceng)既充分(fen)吸收(shou)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)散發(fa)的(de)熱量,又吸收(shou)中層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)熱量,同(tong)時又延長了干(gan)(gan)(gan)(gan)燥(zao)時間,物料(liao)(liao)(liao)(liao)在(zai)(zai)此達到干(gan)(gan)(gan)(gan)燥(zao)狀態。物料(liao)(liao)(liao)(liao)行(xing)至中層(ceng)(ceng)(ceng)(ceng)(ceng)另一端(duan)而落入(ru)(ru)外(wai)(wai)層(ceng)(ceng)(ceng)(ceng)(ceng),物料(liao)(liao)(liao)(liao)在(zai)(zai)外(wai)(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)呈(cheng)矩形多回(hui)(hui)路方(fang)式(shi)(shi)行(xing)進(jin)(jin),達到干(gan)(gan)(gan)(gan)燥(zao)效(xiao)果(guo)的(de)物料(liao)(liao)(liao)(liao)在(zai)(zai)熱風作用下快速(su)行(xing)進(jin)(jin)排出滾(gun)筒(tong),沒有達到干(gan)(gan)(gan)(gan)燥(zao)效(xiao)果(guo)的(de)濕物料(liao)(liao)(liao)(liao)因自重而不能快速(su)行(xing)進(jin)(jin),物料(liao)(liao)(liao)(liao)在(zai)(zai)此矩形抄板內(nei)進(jin)(jin)行(xing)充分(fen)干(gan)(gan)(gan)(gan)燥(zao),由(you)(you)此完成干(gan)(gan)(gan)(gan)燥(zao)目的(de)。
