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。
烘干機筒體(ti)(ti)部分由三個同軸水(shui)平放置的內、中、外筒套疊組成,這就(jiu)使筒體(ti)(ti)的截面(mian)得到充分的利用(yong)。其筒體(ti)(ti)外形總長度(du)約為與之相(xiang)當(dang)的單筒的30-35%。從而大(da)幅(fu)度(du)地減少(shao)占地面(mian)積和廠房建筑(zhu)面(mian)積。
該機的(de)支承裝置,是(shi)在外筒(tong)上輪(lun)(lun)帶(dai)與(yu)托輪(lun)(lun)支承,由電機直(zhi)接帶(dai)動托輪(lun)(lun)。通過(guo)托輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)摩(mo)擦,使筒(tong)體轉動。該機總(zong)體結(jie)構(gou)緊湊、合理、簡單,為便于磨損件的(de)檢(jian)修(xiu)更(geng)換,在中間設(she)計(ji)成(cheng)軸向剖分式(shi),用螺栓固定連接。
工作原理(li)
物(wu)(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝置進(jin)入(ru)回(hui)轉滾(gun)筒的(de)(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng),實現順流烘干(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄板下不(bu)斷抄起、散(san)落(luo)呈(cheng)螺旋行(xing)(xing)進(jin)式實現熱(re)交換,物(wu)(wu)料(liao)(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另(ling)一(yi)端進(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng),進(jin)行(xing)(xing)逆(ni)流烘干(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)不(bu)斷地被反復揚進(jin),呈(cheng)進(jin)兩步(bu)(bu)退一(yi)步(bu)(bu)的(de)(de)(de)行(xing)(xing)進(jin)方式,物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)既充分吸(xi)(xi)收內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒散(san)發的(de)(de)(de)熱(re)量(liang),又吸(xi)(xi)收中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒的(de)(de)(de)熱(re)量(liang),同(tong)時(shi)又延長(chang)了(le)干(gan)(gan)燥(zao)(zao)時(shi)間,物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)(ci)達到干(gan)(gan)燥(zao)(zao)狀(zhuang)態。物(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)另(ling)一(yi)端而落(luo)入(ru)外層(ceng)(ceng)(ceng)(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒內(nei)呈(cheng)矩形多回(hui)路方式行(xing)(xing)進(jin),達到干(gan)(gan)燥(zao)(zao)效果的(de)(de)(de)物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)熱(re)風(feng)作用下快速行(xing)(xing)進(jin)排出(chu)滾(gun)筒,沒有達到干(gan)(gan)燥(zao)(zao)效果的(de)(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)(liao)因自重而不(bu)能(neng)快速行(xing)(xing)進(jin),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)(ci)矩形抄板內(nei)進(jin)行(xing)(xing)充分干(gan)(gan)燥(zao)(zao),由此(ci)(ci)完(wan)成干(gan)(gan)燥(zao)(zao)目(mu)的(de)(de)(de)。
