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)(tong)體(ti)部分(fen)由三(san)個同軸水平(ping)放置的(de)(de)內、中、外筒(tong)(tong)套疊組(zu)成,這就(jiu)使(shi)筒(tong)(tong)體(ti)的(de)(de)截面得(de)到充(chong)分(fen)的(de)(de)利用。其筒(tong)(tong)體(ti)外形(xing)總長(chang)度約為與之相當的(de)(de)單筒(tong)(tong)的(de)(de)30-35%。從而大幅度地(di)減少占地(di)面積(ji)和廠(chang)房建筑面積(ji)。
該機的(de)支承(cheng)裝置(zhi),是在(zai)外筒上(shang)輪(lun)帶(dai)與(yu)托(tuo)(tuo)(tuo)輪(lun)支承(cheng),由(you)電(dian)機直接帶(dai)動(dong)托(tuo)(tuo)(tuo)輪(lun)。通(tong)過托(tuo)(tuo)(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩擦,使(shi)筒體轉動(dong)。該機總體結構(gou)緊湊、合理、簡單,為便(bian)于磨損件的(de)檢修更換,在(zai)中間設計成軸向(xiang)剖分(fen)式(shi),用(yong)螺栓固定連接。
工作原理
物(wu)料(liao)由供(gong)料(liao)裝置進(jin)(jin)(jin)入(ru)回轉(zhuan)滾(gun)筒(tong)的(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實現順(shun)流(liu)烘干(gan)(gan),物(wu)料(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄板下不斷抄起、散落(luo)呈螺旋(xuan)行(xing)進(jin)(jin)(jin)式實現熱(re)交(jiao)換,物(wu)料(liao)移動至(zhi)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)另(ling)一端進(jin)(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)逆流(liu)烘干(gan)(gan),物(wu)料(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不斷地被反復揚(yang)進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩步(bu)退一步(bu)的(de)(de)行(xing)進(jin)(jin)(jin)方式,物(wu)料(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既充(chong)分吸(xi)收內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)散發(fa)的(de)(de)熱(re)量(liang),又(you)吸(xi)收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)(de)熱(re)量(liang),同時又(you)延(yan)長了(le)干(gan)(gan)燥(zao)(zao)時間,物(wu)料(liao)在(zai)(zai)此達(da)到(dao)干(gan)(gan)燥(zao)(zao)狀態。物(wu)料(liao)行(xing)至(zhi)中(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一端而(er)落(luo)入(ru)外層(ceng)(ceng)(ceng)(ceng),物(wu)料(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)呈矩形多回路方式行(xing)進(jin)(jin)(jin),達(da)到(dao)干(gan)(gan)燥(zao)(zao)效果的(de)(de)物(wu)料(liao)在(zai)(zai)熱(re)風作(zuo)用下快速行(xing)進(jin)(jin)(jin)排出滾(gun)筒(tong),沒有(you)達(da)到(dao)干(gan)(gan)燥(zao)(zao)效果的(de)(de)濕物(wu)料(liao)因自重而(er)不能快速行(xing)進(jin)(jin)(jin),物(wu)料(liao)在(zai)(zai)此矩形抄板內(nei)進(jin)(jin)(jin)行(xing)充(chong)分干(gan)(gan)燥(zao)(zao),由此完成干(gan)(gan)燥(zao)(zao)目(mu)的(de)(de)。
