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。
烘干機筒(tong)(tong)(tong)體(ti)部分(fen)由(you)三個同軸水平放(fang)置的內(nei)、中、外筒(tong)(tong)(tong)套疊組(zu)成,這就使筒(tong)(tong)(tong)體(ti)的截面得(de)到充分(fen)的利(li)用。其筒(tong)(tong)(tong)體(ti)外形總長度(du)約為(wei)與之相當(dang)的單(dan)筒(tong)(tong)(tong)的30-35%。從而大幅度(du)地減少(shao)占地面積和廠房建筑面積。
該(gai)機的支承(cheng)裝置,是在外筒上輪(lun)(lun)帶(dai)與(yu)托輪(lun)(lun)支承(cheng),由電機直接帶(dai)動托輪(lun)(lun)。通(tong)過托輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)摩擦(ca),使筒體(ti)轉動。該(gai)機總(zong)體(ti)結構(gou)緊湊(cou)、合理、簡單,為便于(yu)磨損件(jian)的檢修更換,在中間設計成軸(zhou)向剖分(fen)式,用螺栓固定連接。
工作原理
物(wu)(wu)料(liao)(liao)(liao)由(you)供(gong)料(liao)(liao)(liao)裝置進(jin)入回轉滾(gun)筒(tong)的(de)(de)(de)(de)(de)內(nei)層(ceng)(ceng),實現順流(liu)烘(hong)干(gan)(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)在內(nei)層(ceng)(ceng)的(de)(de)(de)(de)(de)抄(chao)板(ban)下(xia)(xia)不(bu)(bu)斷(duan)抄(chao)起(qi)、散落(luo)呈(cheng)螺旋行(xing)進(jin)式實現熱(re)(re)交換,物(wu)(wu)料(liao)(liao)(liao)移動(dong)至(zhi)內(nei)層(ceng)(ceng)的(de)(de)(de)(de)(de)另一端(duan)進(jin)入中(zhong)層(ceng)(ceng),進(jin)行(xing)逆流(liu)烘(hong)干(gan)(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)不(bu)(bu)斷(duan)地被反復揚進(jin),呈(cheng)進(jin)兩(liang)步退(tui)一步的(de)(de)(de)(de)(de)行(xing)進(jin)方式,物(wu)(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)既充(chong)分吸(xi)收內(nei)層(ceng)(ceng)滾(gun)筒(tong)散發的(de)(de)(de)(de)(de)熱(re)(re)量,又(you)吸(xi)收中(zhong)層(ceng)(ceng)滾(gun)筒(tong)的(de)(de)(de)(de)(de)熱(re)(re)量,同(tong)時又(you)延長了干(gan)(gan)(gan)燥(zao)時間(jian),物(wu)(wu)料(liao)(liao)(liao)在此達(da)(da)到(dao)干(gan)(gan)(gan)燥(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)行(xing)至(zhi)中(zhong)層(ceng)(ceng)另一端(duan)而落(luo)入外層(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)在外層(ceng)(ceng)滾(gun)筒(tong)內(nei)呈(cheng)矩形多回路方式行(xing)進(jin),達(da)(da)到(dao)干(gan)(gan)(gan)燥(zao)效(xiao)果的(de)(de)(de)(de)(de)物(wu)(wu)料(liao)(liao)(liao)在熱(re)(re)風作用下(xia)(xia)快速行(xing)進(jin)排(pai)出滾(gun)筒(tong),沒有達(da)(da)到(dao)干(gan)(gan)(gan)燥(zao)效(xiao)果的(de)(de)(de)(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)因自重而不(bu)(bu)能(neng)快速行(xing)進(jin),物(wu)(wu)料(liao)(liao)(liao)在此矩形抄(chao)板(ban)內(nei)進(jin)行(xing)充(chong)分干(gan)(gan)(gan)燥(zao),由(you)此完成干(gan)(gan)(gan)燥(zao)目(mu)的(de)(de)(de)(de)(de)。
