產品結構
三筒式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(ti)部分由三個(ge)同(tong)軸水(shui)平放置的(de)內、中、外筒(tong)套疊組成,這(zhe)就使筒(tong)體(ti)的(de)截面(mian)(mian)得(de)到充分的(de)利用。其筒(tong)體(ti)外形總(zong)長度約(yue)為與之(zhi)相當(dang)的(de)單(dan)筒(tong)的(de)30-35%。從而大幅度地減少占(zhan)地面(mian)(mian)積和廠房建筑面(mian)(mian)積。
該機(ji)的支承(cheng)裝(zhuang)置,是在外筒上輪(lun)(lun)帶與托(tuo)(tuo)輪(lun)(lun)支承(cheng),由電機(ji)直接帶動托(tuo)(tuo)輪(lun)(lun)。通(tong)過托(tuo)(tuo)輪(lun)(lun)與輪(lun)(lun)帶摩擦,使筒體轉動。該機(ji)總體結構緊湊、合理、簡單,為便(bian)于磨損件的檢(jian)修更換,在中間(jian)設計(ji)成軸向剖分式(shi),用螺栓固定連(lian)接。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)(jin)入回(hui)轉滾筒的(de)(de)(de)內(nei)層(ceng)(ceng)(ceng),實現順流(liu)烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)抄板下不(bu)斷(duan)抄起、散落呈螺旋行(xing)(xing)進(jin)(jin)(jin)(jin)式實現熱(re)(re)交(jiao)換,物(wu)(wu)(wu)(wu)料(liao)(liao)移(yi)動至(zhi)內(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)另一端進(jin)(jin)(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)行(xing)(xing)逆流(liu)烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)不(bu)斷(duan)地被(bei)反復揚進(jin)(jin)(jin)(jin),呈進(jin)(jin)(jin)(jin)兩(liang)步退一步的(de)(de)(de)行(xing)(xing)進(jin)(jin)(jin)(jin)方式,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)既(ji)充(chong)分吸收內(nei)層(ceng)(ceng)(ceng)滾筒散發(fa)的(de)(de)(de)熱(re)(re)量(liang),又吸收中(zhong)層(ceng)(ceng)(ceng)滾筒的(de)(de)(de)熱(re)(re)量(liang),同時又延長了干(gan)燥(zao)時間,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)達到(dao)(dao)干(gan)燥(zao)狀態(tai)。物(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)至(zhi)中(zhong)層(ceng)(ceng)(ceng)另一端而落入外層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)滾筒內(nei)呈矩形多回(hui)路方式行(xing)(xing)進(jin)(jin)(jin)(jin),達到(dao)(dao)干(gan)燥(zao)效果(guo)的(de)(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)熱(re)(re)風(feng)作用下快速行(xing)(xing)進(jin)(jin)(jin)(jin)排出滾筒,沒(mei)有達到(dao)(dao)干(gan)燥(zao)效果(guo)的(de)(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)因(yin)自(zi)重而不(bu)能快速行(xing)(xing)進(jin)(jin)(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)矩形抄板內(nei)進(jin)(jin)(jin)(jin)行(xing)(xing)充(chong)分干(gan)燥(zao),由此(ci)完(wan)成干(gan)燥(zao)目的(de)(de)(de)。
