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(ti)部分(fen)由三個同軸水平放置的(de)(de)內、中、外筒(tong)套疊組(zu)成(cheng),這就使筒(tong)體(ti)的(de)(de)截面(mian)得到充(chong)分(fen)的(de)(de)利用(yong)。其(qi)筒(tong)體(ti)外形總長度約為(wei)與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度地減(jian)少占地面(mian)積和廠房建筑面(mian)積。
該(gai)機的(de)支(zhi)承裝置,是在外筒上輪(lun)帶(dai)與(yu)托(tuo)(tuo)(tuo)輪(lun)支(zhi)承,由電機直接(jie)帶(dai)動托(tuo)(tuo)(tuo)輪(lun)。通過托(tuo)(tuo)(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩擦,使筒體轉動。該(gai)機總體結構緊湊、合理、簡單,為便(bian)于(yu)磨損件(jian)的(de)檢修(xiu)更(geng)換,在中間設計(ji)成軸(zhou)向(xiang)剖分式,用螺栓固定連接(jie)。
工作原理
物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)由(you)供料(liao)裝置(zhi)進入回(hui)轉滾(gun)(gun)筒(tong)的(de)內層(ceng)(ceng)(ceng),實(shi)現順流烘干,物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)內層(ceng)(ceng)(ceng)的(de)抄(chao)(chao)板下(xia)不(bu)(bu)斷(duan)抄(chao)(chao)起、散落(luo)呈螺(luo)旋行(xing)(xing)(xing)(xing)進式實(shi)現熱(re)(re)交換,物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)移(yi)動至(zhi)內層(ceng)(ceng)(ceng)的(de)另(ling)一(yi)端進入中層(ceng)(ceng)(ceng),進行(xing)(xing)(xing)(xing)逆流烘干,物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)中層(ceng)(ceng)(ceng)不(bu)(bu)斷(duan)地被反(fan)復(fu)揚進,呈進兩步退一(yi)步的(de)行(xing)(xing)(xing)(xing)進方(fang)式,物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)中層(ceng)(ceng)(ceng)既(ji)充分(fen)吸(xi)收(shou)(shou)內層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散發(fa)的(de)熱(re)(re)量,又吸(xi)收(shou)(shou)中層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)熱(re)(re)量,同時(shi)又延長了(le)干燥(zao)時(shi)間,物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)此(ci)達(da)到干燥(zao)狀態(tai)。物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)行(xing)(xing)(xing)(xing)至(zhi)中層(ceng)(ceng)(ceng)另(ling)一(yi)端而落(luo)入外層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)外層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內呈矩形多回(hui)路方(fang)式行(xing)(xing)(xing)(xing)進,達(da)到干燥(zao)效(xiao)果的(de)物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)熱(re)(re)風作用下(xia)快速行(xing)(xing)(xing)(xing)進排出滾(gun)(gun)筒(tong),沒有達(da)到干燥(zao)效(xiao)果的(de)濕物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)因自重而不(bu)(bu)能快速行(xing)(xing)(xing)(xing)進,物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)此(ci)矩形抄(chao)(chao)板內進行(xing)(xing)(xing)(xing)充分(fen)干燥(zao),由(you)此(ci)完成(cheng)干燥(zao)目的(de)。
