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(gan)機筒(tong)體部(bu)分由三個(ge)同軸水平放置的(de)內、中、外筒(tong)套疊組成(cheng),這就(jiu)使筒(tong)體的(de)截面(mian)得到充分的(de)利(li)用(yong)。其筒(tong)體外形總長度(du)約(yue)為與之相(xiang)當的(de)單筒(tong)的(de)30-35%。從而大幅(fu)度(du)地減少占地面(mian)積(ji)和廠房建筑面(mian)積(ji)。
該(gai)機的(de)支承裝置,是在(zai)外筒(tong)(tong)上輪帶(dai)與托(tuo)(tuo)輪支承,由電(dian)機直接帶(dai)動托(tuo)(tuo)輪。通(tong)過托(tuo)(tuo)輪與輪帶(dai)摩擦(ca),使筒(tong)(tong)體轉動。該(gai)機總(zong)體結構緊湊(cou)、合理、簡單,為(wei)便(bian)于磨損件(jian)的(de)檢修更換,在(zai)中間設計成軸向(xiang)剖分式,用螺栓固定連接。
工作原理
物(wu)料(liao)由(you)供料(liao)裝(zhuang)置進(jin)(jin)入(ru)(ru)(ru)回轉滾(gun)筒(tong)的(de)(de)內(nei)層(ceng)(ceng),實(shi)現(xian)順(shun)流烘干(gan)(gan),物(wu)料(liao)在(zai)(zai)內(nei)層(ceng)(ceng)的(de)(de)抄板下(xia)(xia)不斷抄起、散落呈(cheng)螺(luo)旋行(xing)(xing)進(jin)(jin)式(shi)實(shi)現(xian)熱交換,物(wu)料(liao)移動至(zhi)(zhi)內(nei)層(ceng)(ceng)的(de)(de)另(ling)一(yi)端(duan)(duan)進(jin)(jin)入(ru)(ru)(ru)中(zhong)層(ceng)(ceng),進(jin)(jin)行(xing)(xing)逆流烘干(gan)(gan),物(wu)料(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)不斷地被(bei)反(fan)復揚進(jin)(jin),呈(cheng)進(jin)(jin)兩步(bu)退一(yi)步(bu)的(de)(de)行(xing)(xing)進(jin)(jin)方式(shi),物(wu)料(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)既(ji)充(chong)(chong)分吸收(shou)內(nei)層(ceng)(ceng)滾(gun)筒(tong)散發的(de)(de)熱量,又(you)吸收(shou)中(zhong)層(ceng)(ceng)滾(gun)筒(tong)的(de)(de)熱量,同(tong)時又(you)延長了干(gan)(gan)燥(zao)(zao)時間,物(wu)料(liao)在(zai)(zai)此(ci)達到(dao)干(gan)(gan)燥(zao)(zao)狀(zhuang)態。物(wu)料(liao)行(xing)(xing)至(zhi)(zhi)中(zhong)層(ceng)(ceng)另(ling)一(yi)端(duan)(duan)而落入(ru)(ru)(ru)外層(ceng)(ceng),物(wu)料(liao)在(zai)(zai)外層(ceng)(ceng)滾(gun)筒(tong)內(nei)呈(cheng)矩(ju)(ju)形多回路(lu)方式(shi)行(xing)(xing)進(jin)(jin),達到(dao)干(gan)(gan)燥(zao)(zao)效(xiao)果的(de)(de)物(wu)料(liao)在(zai)(zai)熱風作用下(xia)(xia)快(kuai)(kuai)速行(xing)(xing)進(jin)(jin)排出(chu)滾(gun)筒(tong),沒(mei)有達到(dao)干(gan)(gan)燥(zao)(zao)效(xiao)果的(de)(de)濕物(wu)料(liao)因自(zi)重而不能(neng)快(kuai)(kuai)速行(xing)(xing)進(jin)(jin),物(wu)料(liao)在(zai)(zai)此(ci)矩(ju)(ju)形抄板內(nei)進(jin)(jin)行(xing)(xing)充(chong)(chong)分干(gan)(gan)燥(zao)(zao),由(you)此(ci)完成干(gan)(gan)燥(zao)(zao)目的(de)(de)。
