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(gan)機筒體(ti)部分由三個同(tong)軸水平放(fang)置的(de)內、中、外(wai)筒套疊組(zu)成,這就使筒體(ti)的(de)截(jie)面(mian)得到充分的(de)利用。其筒體(ti)外(wai)形總長度約為與之相當的(de)單筒的(de)30-35%。從(cong)而大幅度地減少占地面(mian)積和廠(chang)房(fang)建筑(zhu)面(mian)積。
該(gai)機(ji)的支承裝置,是在外(wai)筒上輪(lun)帶(dai)(dai)與托輪(lun)支承,由電機(ji)直接帶(dai)(dai)動(dong)托輪(lun)。通過托輪(lun)與輪(lun)帶(dai)(dai)摩擦(ca),使筒體(ti)轉動(dong)。該(gai)機(ji)總體(ti)結構緊湊(cou)、合(he)理、簡(jian)單,為便(bian)于磨(mo)損件的檢(jian)修更換(huan),在中間設計成軸向剖分式,用螺栓固(gu)定連接。
工作原理
物(wu)(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝置進(jin)(jin)(jin)入回轉滾(gun)(gun)(gun)筒(tong)(tong)的(de)(de)(de)內層(ceng)(ceng)(ceng)(ceng)(ceng),實(shi)現(xian)(xian)順流烘干,物(wu)(wu)料(liao)(liao)(liao)(liao)在內層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄板下(xia)不(bu)斷抄起、散落(luo)呈螺旋行(xing)進(jin)(jin)(jin)式實(shi)現(xian)(xian)熱(re)交換,物(wu)(wu)料(liao)(liao)(liao)(liao)移動至內層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另(ling)一端(duan)進(jin)(jin)(jin)入中層(ceng)(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)逆(ni)流烘干,物(wu)(wu)料(liao)(liao)(liao)(liao)在中層(ceng)(ceng)(ceng)(ceng)(ceng)不(bu)斷地(di)被反(fan)復(fu)揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩(liang)步退(tui)一步的(de)(de)(de)行(xing)進(jin)(jin)(jin)方(fang)式,物(wu)(wu)料(liao)(liao)(liao)(liao)在中層(ceng)(ceng)(ceng)(ceng)(ceng)既充(chong)分吸(xi)收(shou)(shou)內層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)散發(fa)的(de)(de)(de)熱(re)量,又吸(xi)收(shou)(shou)中層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)的(de)(de)(de)熱(re)量,同(tong)時(shi)又延長了(le)干燥(zao)時(shi)間,物(wu)(wu)料(liao)(liao)(liao)(liao)在此(ci)(ci)達(da)到干燥(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)至中層(ceng)(ceng)(ceng)(ceng)(ceng)另(ling)一端(duan)而落(luo)入外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)(liao)在外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)內呈矩形(xing)多回路方(fang)式行(xing)進(jin)(jin)(jin),達(da)到干燥(zao)效果的(de)(de)(de)物(wu)(wu)料(liao)(liao)(liao)(liao)在熱(re)風(feng)作用下(xia)快速(su)行(xing)進(jin)(jin)(jin)排出(chu)滾(gun)(gun)(gun)筒(tong)(tong),沒有達(da)到干燥(zao)效果的(de)(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)(liao)因(yin)自重而不(bu)能(neng)快速(su)行(xing)進(jin)(jin)(jin),物(wu)(wu)料(liao)(liao)(liao)(liao)在此(ci)(ci)矩形(xing)抄板內進(jin)(jin)(jin)行(xing)充(chong)分干燥(zao),由此(ci)(ci)完(wan)成(cheng)干燥(zao)目的(de)(de)(de)。
