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(tong)(tong)體(ti)部分由三個同軸(zhou)水(shui)平放置(zhi)的內(nei)、中、外筒(tong)(tong)套疊組成(cheng),這就(jiu)使筒(tong)(tong)體(ti)的截面得到充(chong)分的利用。其(qi)筒(tong)(tong)體(ti)外形總(zong)長(chang)度(du)約(yue)為與之相當(dang)的單筒(tong)(tong)的30-35%。從而大幅度(du)地減少占地面積和廠房(fang)建筑面積。
該(gai)機的支承裝置,是在(zai)外(wai)筒上(shang)輪帶與(yu)托輪支承,由電機直接帶動(dong)托輪。通過(guo)托輪與(yu)輪帶摩(mo)擦,使筒體轉(zhuan)動(dong)。該(gai)機總體結構緊湊、合(he)理、簡單,為便于(yu)磨損件的檢修更換(huan),在(zai)中間設計成軸向剖分(fen)式,用螺(luo)栓固定連接。
工作(zuo)原理
物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)(liao)裝置進(jin)(jin)入(ru)回轉(zhuan)滾(gun)筒(tong)的(de)(de)(de)內(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng),實現順流烘(hong)干,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)內(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)板(ban)(ban)下(xia)不斷抄(chao)起、散(san)(san)落呈螺旋行進(jin)(jin)式(shi)實現熱(re)交(jiao)換,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移動至內(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另(ling)一(yi)端進(jin)(jin)入(ru)中層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)行逆流烘(hong)干,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)(ceng)不斷地被反復揚進(jin)(jin),呈進(jin)(jin)兩步退一(yi)步的(de)(de)(de)行進(jin)(jin)方(fang)式(shi),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)(ceng)既充分吸收(shou)內(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)散(san)(san)發的(de)(de)(de)熱(re)量(liang)(liang),又(you)(you)吸收(shou)中層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)(de)(de)熱(re)量(liang)(liang),同時(shi)(shi)又(you)(you)延(yan)長了干燥時(shi)(shi)間,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)此(ci)(ci)達到(dao)干燥狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行至中層(ceng)(ceng)(ceng)(ceng)另(ling)一(yi)端而落入(ru)外(wai)層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)(nei)(nei)呈矩形多回路方(fang)式(shi)行進(jin)(jin),達到(dao)干燥效果的(de)(de)(de)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)熱(re)風作用下(xia)快速行進(jin)(jin)排出滾(gun)筒(tong),沒有達到(dao)干燥效果的(de)(de)(de)濕(shi)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因自重而不能快速行進(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)此(ci)(ci)矩形抄(chao)板(ban)(ban)內(nei)(nei)(nei)進(jin)(jin)行充分干燥,由(you)此(ci)(ci)完成干燥目(mu)的(de)(de)(de)。
