產品結構
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。
烘干機筒(tong)體部分由三個(ge)同(tong)軸水(shui)平放置的(de)內、中(zhong)、外筒(tong)套(tao)疊組成,這就使筒(tong)體的(de)截面(mian)得到充(chong)分的(de)利(li)用。其筒(tong)體外形總(zong)長度約為與(yu)之相當(dang)的(de)單筒(tong)的(de)30-35%。從而大幅(fu)度地減少占地面(mian)積和廠房建筑面(mian)積。
該(gai)(gai)機(ji)(ji)的支承(cheng)裝置,是(shi)在外筒(tong)上輪(lun)(lun)帶(dai)與托輪(lun)(lun)支承(cheng),由電(dian)機(ji)(ji)直接(jie)帶(dai)動托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使筒(tong)體(ti)轉(zhuan)動。該(gai)(gai)機(ji)(ji)總體(ti)結構緊湊、合理、簡(jian)單(dan),為便于磨(mo)損件(jian)的檢修更換(huan),在中間設計成軸(zhou)向剖(pou)分式,用(yong)螺栓固定連(lian)接(jie)。
工(gong)作(zuo)原理
物(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)入回轉滾(gun)(gun)筒(tong)(tong)的(de)(de)(de)(de)內(nei)層(ceng)(ceng),實(shi)現順流(liu)烘干(gan)(gan),物(wu)(wu)料(liao)(liao)在內(nei)層(ceng)(ceng)的(de)(de)(de)(de)抄板(ban)下不(bu)斷抄起、散落呈(cheng)螺旋(xuan)行(xing)(xing)進(jin)式(shi)(shi)實(shi)現熱交換,物(wu)(wu)料(liao)(liao)移動至內(nei)層(ceng)(ceng)的(de)(de)(de)(de)另(ling)一端進(jin)入中(zhong)層(ceng)(ceng),進(jin)行(xing)(xing)逆(ni)流(liu)烘干(gan)(gan),物(wu)(wu)料(liao)(liao)在中(zhong)層(ceng)(ceng)不(bu)斷地被反復揚進(jin),呈(cheng)進(jin)兩(liang)步(bu)(bu)退(tui)一步(bu)(bu)的(de)(de)(de)(de)行(xing)(xing)進(jin)方式(shi)(shi),物(wu)(wu)料(liao)(liao)在中(zhong)層(ceng)(ceng)既充分吸收(shou)內(nei)層(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)散發的(de)(de)(de)(de)熱量,又(you)吸收(shou)中(zhong)層(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)的(de)(de)(de)(de)熱量,同時又(you)延長了干(gan)(gan)燥(zao)時間,物(wu)(wu)料(liao)(liao)在此達(da)到(dao)干(gan)(gan)燥(zao)狀(zhuang)態。物(wu)(wu)料(liao)(liao)行(xing)(xing)至中(zhong)層(ceng)(ceng)另(ling)一端而(er)(er)落入外層(ceng)(ceng),物(wu)(wu)料(liao)(liao)在外層(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)內(nei)呈(cheng)矩形(xing)多(duo)回路方式(shi)(shi)行(xing)(xing)進(jin),達(da)到(dao)干(gan)(gan)燥(zao)效(xiao)果的(de)(de)(de)(de)物(wu)(wu)料(liao)(liao)在熱風(feng)作用(yong)下快速(su)行(xing)(xing)進(jin)排出滾(gun)(gun)筒(tong)(tong),沒有達(da)到(dao)干(gan)(gan)燥(zao)效(xiao)果的(de)(de)(de)(de)濕物(wu)(wu)料(liao)(liao)因自重而(er)(er)不(bu)能快速(su)行(xing)(xing)進(jin),物(wu)(wu)料(liao)(liao)在此矩形(xing)抄板(ban)內(nei)進(jin)行(xing)(xing)充分干(gan)(gan)燥(zao),由此完成(cheng)干(gan)(gan)燥(zao)目的(de)(de)(de)(de)。
