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。
烘干機筒(tong)體部分由(you)三個同軸水平放置的內、中、外筒(tong)套疊組成,這就使筒(tong)體的截面得(de)到充分的利用。其筒(tong)體外形總長度約為(wei)與之相(xiang)當的單筒(tong)的30-35%。從而大幅(fu)度地(di)減(jian)少(shao)占地(di)面積和廠房建筑面積。
該(gai)機的(de)支承(cheng)裝置,是在外(wai)筒上輪(lun)帶(dai)與(yu)(yu)托(tuo)輪(lun)支承(cheng),由(you)電機直接帶(dai)動(dong)(dong)托(tuo)輪(lun)。通(tong)過托(tuo)輪(lun)與(yu)(yu)輪(lun)帶(dai)摩擦,使筒體轉動(dong)(dong)。該(gai)機總體結構(gou)緊湊、合理、簡單,為便(bian)于磨(mo)損件的(de)檢修更(geng)換,在中(zhong)間設計成(cheng)軸(zhou)向剖分(fen)式,用螺栓固定連接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)由(you)供(gong)料(liao)(liao)裝置進(jin)(jin)(jin)(jin)入(ru)(ru)回轉滾(gun)(gun)筒(tong)(tong)(tong)的(de)(de)內(nei)(nei)層(ceng),實現順流烘(hong)干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)內(nei)(nei)層(ceng)的(de)(de)抄板下(xia)不(bu)斷抄起(qi)、散落(luo)呈(cheng)螺旋行(xing)(xing)進(jin)(jin)(jin)(jin)式(shi)實現熱交換(huan),物(wu)(wu)(wu)料(liao)(liao)移動至內(nei)(nei)層(ceng)的(de)(de)另一端(duan)進(jin)(jin)(jin)(jin)入(ru)(ru)中層(ceng),進(jin)(jin)(jin)(jin)行(xing)(xing)逆流烘(hong)干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)中層(ceng)不(bu)斷地(di)被反(fan)復揚(yang)進(jin)(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)(jin)兩步退(tui)一步的(de)(de)行(xing)(xing)進(jin)(jin)(jin)(jin)方式(shi),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)中層(ceng)既充分吸(xi)收內(nei)(nei)層(ceng)滾(gun)(gun)筒(tong)(tong)(tong)散發的(de)(de)熱量,又(you)(you)吸(xi)收中層(ceng)滾(gun)(gun)筒(tong)(tong)(tong)的(de)(de)熱量,同時又(you)(you)延(yan)長了干(gan)(gan)燥(zao)(zao)時間,物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)此達(da)到(dao)干(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)至中層(ceng)另一端(duan)而落(luo)入(ru)(ru)外(wai)層(ceng),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)外(wai)層(ceng)滾(gun)(gun)筒(tong)(tong)(tong)內(nei)(nei)呈(cheng)矩形多回路(lu)方式(shi)行(xing)(xing)進(jin)(jin)(jin)(jin),達(da)到(dao)干(gan)(gan)燥(zao)(zao)效(xiao)果的(de)(de)物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)熱風作用下(xia)快(kuai)速(su)行(xing)(xing)進(jin)(jin)(jin)(jin)排出滾(gun)(gun)筒(tong)(tong)(tong),沒有達(da)到(dao)干(gan)(gan)燥(zao)(zao)效(xiao)果的(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)因自重而不(bu)能快(kuai)速(su)行(xing)(xing)進(jin)(jin)(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)此矩形抄板內(nei)(nei)進(jin)(jin)(jin)(jin)行(xing)(xing)充分干(gan)(gan)燥(zao)(zao),由(you)此完(wan)成干(gan)(gan)燥(zao)(zao)目的(de)(de)。
