產品結(jie)構
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(gan)機筒體(ti)部分(fen)由三個同軸(zhou)水平(ping)放置的內、中、外(wai)筒套疊組成,這就使筒體(ti)的截面得(de)到充分(fen)的利用。其筒體(ti)外(wai)形總(zong)長度約為(wei)與之相(xiang)當的單筒的30-35%。從(cong)而大幅度地(di)減(jian)少(shao)占地(di)面積和廠房(fang)建筑面積。
該機(ji)(ji)的支承裝(zhuang)置(zhi),是在外筒(tong)上輪(lun)帶(dai)與托(tuo)輪(lun)支承,由電(dian)機(ji)(ji)直(zhi)接帶(dai)動托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶(dai)摩擦(ca),使筒(tong)體(ti)轉動。該機(ji)(ji)總(zong)體(ti)結構緊湊、合理、簡(jian)單,為便于磨損件的檢修(xiu)更換,在中(zhong)間(jian)設計成軸向剖分式,用螺栓(shuan)固定連(lian)接。
工作原理
物(wu)料(liao)(liao)由(you)供料(liao)(liao)裝置進(jin)(jin)入(ru)回(hui)轉滾(gun)筒的內層(ceng)(ceng)(ceng),實現順流烘(hong)干(gan),物(wu)料(liao)(liao)在(zai)內層(ceng)(ceng)(ceng)的抄板下不斷抄起(qi)、散(san)落呈(cheng)螺(luo)旋(xuan)行(xing)(xing)(xing)(xing)進(jin)(jin)式實現熱(re)(re)交換,物(wu)料(liao)(liao)移動至(zhi)內層(ceng)(ceng)(ceng)的另一端進(jin)(jin)入(ru)中層(ceng)(ceng)(ceng),進(jin)(jin)行(xing)(xing)(xing)(xing)逆流烘(hong)干(gan),物(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)不斷地被(bei)反復揚(yang)進(jin)(jin),呈(cheng)進(jin)(jin)兩步退一步的行(xing)(xing)(xing)(xing)進(jin)(jin)方式,物(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)既充分吸(xi)(xi)收內層(ceng)(ceng)(ceng)滾(gun)筒散(san)發的熱(re)(re)量(liang),又吸(xi)(xi)收中層(ceng)(ceng)(ceng)滾(gun)筒的熱(re)(re)量(liang),同時又延長了干(gan)燥(zao)時間,物(wu)料(liao)(liao)在(zai)此(ci)達到干(gan)燥(zao)狀態。物(wu)料(liao)(liao)行(xing)(xing)(xing)(xing)至(zhi)中層(ceng)(ceng)(ceng)另一端而落入(ru)外層(ceng)(ceng)(ceng),物(wu)料(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)滾(gun)筒內呈(cheng)矩(ju)形(xing)多回(hui)路方式行(xing)(xing)(xing)(xing)進(jin)(jin),達到干(gan)燥(zao)效(xiao)果的物(wu)料(liao)(liao)在(zai)熱(re)(re)風作(zuo)用(yong)下快速行(xing)(xing)(xing)(xing)進(jin)(jin)排(pai)出滾(gun)筒,沒有達到干(gan)燥(zao)效(xiao)果的濕物(wu)料(liao)(liao)因自重而不能快速行(xing)(xing)(xing)(xing)進(jin)(jin),物(wu)料(liao)(liao)在(zai)此(ci)矩(ju)形(xing)抄板內進(jin)(jin)行(xing)(xing)(xing)(xing)充分干(gan)燥(zao),由(you)此(ci)完(wan)成(cheng)干(gan)燥(zao)目的。
