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(you)三(san)個同(tong)軸(zhou)水平放置(zhi)的(de)(de)內、中、外筒(tong)(tong)套疊組成,這就使筒(tong)(tong)體(ti)的(de)(de)截面(mian)得(de)到充分的(de)(de)利用。其筒(tong)(tong)體(ti)外形總長度約(yue)為(wei)與之相當的(de)(de)單筒(tong)(tong)的(de)(de)30-35%。從而大幅度地減少占地面(mian)積和廠房建(jian)筑面(mian)積。
該機的(de)支(zhi)承裝(zhuang)置(zhi),是在(zai)外筒上輪(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)支(zhi)承,由(you)電(dian)機直接(jie)帶(dai)動(dong)托(tuo)輪(lun)(lun)。通過(guo)托(tuo)輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使筒體(ti)轉(zhuan)動(dong)。該機總體(ti)結構(gou)緊湊、合理、簡(jian)單,為便于磨損件的(de)檢修更換,在(zai)中間設計成(cheng)軸向(xiang)剖分式,用螺(luo)栓固(gu)定連接(jie)。
工作原理
物(wu)料(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)裝(zhuang)置進入回(hui)轉滾(gun)筒(tong)的(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實(shi)現(xian)順(shun)流烘干(gan)(gan)(gan),物(wu)料(liao)(liao)(liao)在內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄板下不(bu)斷(duan)抄起、散落(luo)呈螺旋行(xing)進式實(shi)現(xian)熱交換,物(wu)料(liao)(liao)(liao)移動至(zhi)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)另一(yi)(yi)端進入中(zhong)層(ceng)(ceng)(ceng)(ceng),進行(xing)逆(ni)流烘干(gan)(gan)(gan),物(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷(duan)地被反復(fu)揚進,呈進兩步(bu)退一(yi)(yi)步(bu)的(de)(de)行(xing)進方式,物(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分(fen)吸(xi)收(shou)內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)散發(fa)的(de)(de)熱量(liang),又吸(xi)收(shou)中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)(de)熱量(liang),同時(shi)又延長了干(gan)(gan)(gan)燥(zao)(zao)時(shi)間,物(wu)料(liao)(liao)(liao)在此(ci)達到干(gan)(gan)(gan)燥(zao)(zao)狀態。物(wu)料(liao)(liao)(liao)行(xing)至(zhi)中(zhong)層(ceng)(ceng)(ceng)(ceng)另一(yi)(yi)端而(er)落(luo)入外(wai)層(ceng)(ceng)(ceng)(ceng),物(wu)料(liao)(liao)(liao)在外(wai)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)呈矩形多(duo)回(hui)路方式行(xing)進,達到干(gan)(gan)(gan)燥(zao)(zao)效果的(de)(de)物(wu)料(liao)(liao)(liao)在熱風作用下快速行(xing)進排出(chu)滾(gun)筒(tong),沒有(you)達到干(gan)(gan)(gan)燥(zao)(zao)效果的(de)(de)濕(shi)物(wu)料(liao)(liao)(liao)因(yin)自重而(er)不(bu)能(neng)快速行(xing)進,物(wu)料(liao)(liao)(liao)在此(ci)矩形抄板內(nei)進行(xing)充分(fen)干(gan)(gan)(gan)燥(zao)(zao),由此(ci)完成(cheng)干(gan)(gan)(gan)燥(zao)(zao)目的(de)(de)。
