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(you)三個同軸水平放置的(de)內、中、外筒(tong)套疊組成,這就(jiu)使筒(tong)體的(de)截(jie)面得到充(chong)分的(de)利用(yong)。其筒(tong)體外形(xing)總長度約為與之相當的(de)單筒(tong)的(de)30-35%。從(cong)而大幅度地減(jian)少占地面積(ji)和廠房建(jian)筑面積(ji)。
該機的支承裝置,是在(zai)外筒(tong)上輪(lun)帶與(yu)托輪(lun)支承,由電(dian)機直接帶動托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶摩擦,使筒(tong)體轉(zhuan)動。該機總體結構緊湊、合理、簡單,為便于磨損(sun)件的檢修(xiu)更換(huan),在(zai)中間設計成(cheng)軸向剖分式(shi),用(yong)螺栓固定連接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)裝(zhuang)置進(jin)入(ru)回轉(zhuan)滾(gun)(gun)(gun)筒(tong)的(de)內層(ceng)(ceng)(ceng),實現順流烘干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)內層(ceng)(ceng)(ceng)的(de)抄(chao)板下(xia)不(bu)斷(duan)抄(chao)起、散(san)落(luo)呈(cheng)(cheng)螺旋行(xing)(xing)進(jin)式(shi)(shi)實現熱交(jiao)換(huan),物(wu)(wu)(wu)料(liao)(liao)(liao)移動至內層(ceng)(ceng)(ceng)的(de)另(ling)一(yi)端進(jin)入(ru)中層(ceng)(ceng)(ceng),進(jin)行(xing)(xing)逆流烘干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)中層(ceng)(ceng)(ceng)不(bu)斷(duan)地被反復揚進(jin),呈(cheng)(cheng)進(jin)兩步(bu)(bu)退一(yi)步(bu)(bu)的(de)行(xing)(xing)進(jin)方式(shi)(shi),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)中層(ceng)(ceng)(ceng)既充分(fen)吸收內層(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)散(san)發的(de)熱量(liang),又吸收中層(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)的(de)熱量(liang),同時又延(yan)長了干(gan)(gan)燥(zao)(zao)時間(jian),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)此(ci)達(da)到(dao)(dao)干(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)至中層(ceng)(ceng)(ceng)另(ling)一(yi)端而(er)落(luo)入(ru)外層(ceng)(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)外層(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)內呈(cheng)(cheng)矩形(xing)多回路方式(shi)(shi)行(xing)(xing)進(jin),達(da)到(dao)(dao)干(gan)(gan)燥(zao)(zao)效果(guo)的(de)物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)熱風作用(yong)下(xia)快(kuai)速行(xing)(xing)進(jin)排出滾(gun)(gun)(gun)筒(tong),沒(mei)有達(da)到(dao)(dao)干(gan)(gan)燥(zao)(zao)效果(guo)的(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)因自重而(er)不(bu)能快(kuai)速行(xing)(xing)進(jin),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)此(ci)矩形(xing)抄(chao)板內進(jin)行(xing)(xing)充分(fen)干(gan)(gan)燥(zao)(zao),由此(ci)完(wan)成干(gan)(gan)燥(zao)(zao)目的(de)。
