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)(tong)體(ti)(ti)部分由三個(ge)同軸水(shui)平放置的(de)內、中(zhong)、外筒(tong)(tong)套疊組成,這(zhe)就使筒(tong)(tong)體(ti)(ti)的(de)截面(mian)(mian)得(de)到充分的(de)利用。其筒(tong)(tong)體(ti)(ti)外形總長度約為與之(zhi)相當(dang)的(de)單(dan)筒(tong)(tong)的(de)30-35%。從而(er)大幅度地(di)減(jian)少占地(di)面(mian)(mian)積(ji)和廠房(fang)建筑面(mian)(mian)積(ji)。
該(gai)機的支(zhi)承裝(zhuang)置(zhi),是(shi)在外(wai)筒(tong)上輪帶與托輪支(zhi)承,由電(dian)機直接(jie)帶動托輪。通過托輪與輪帶摩擦,使(shi)筒(tong)體轉(zhuan)動。該(gai)機總體結構(gou)緊湊、合理(li)、簡(jian)單,為(wei)便于磨損(sun)件的檢修更換,在中間設計成軸向剖分式,用螺栓固定連接(jie)。
工作原理
物(wu)料由(you)供(gong)料裝置進(jin)(jin)(jin)(jin)(jin)入回轉滾(gun)(gun)(gun)筒的(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實現(xian)順流烘(hong)干(gan)(gan)(gan),物(wu)料在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄(chao)板下不斷抄(chao)起、散落呈(cheng)螺旋行(xing)進(jin)(jin)(jin)(jin)(jin)式(shi)實現(xian)熱(re)交換,物(wu)料移動至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)另(ling)一端進(jin)(jin)(jin)(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)(jin)行(xing)逆流烘(hong)干(gan)(gan)(gan),物(wu)料在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不斷地被反復揚(yang)進(jin)(jin)(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)(jin)(jin)兩步(bu)退(tui)一步(bu)的(de)(de)行(xing)進(jin)(jin)(jin)(jin)(jin)方(fang)式(shi),物(wu)料在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既(ji)充分(fen)吸收內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒散發的(de)(de)熱(re)量,又吸收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒的(de)(de)熱(re)量,同時又延長了干(gan)(gan)(gan)燥(zao)時間,物(wu)料在(zai)(zai)此(ci)達到干(gan)(gan)(gan)燥(zao)狀態。物(wu)料行(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一端而落入外層(ceng)(ceng)(ceng)(ceng),物(wu)料在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒內(nei)呈(cheng)矩形多回路方(fang)式(shi)行(xing)進(jin)(jin)(jin)(jin)(jin),達到干(gan)(gan)(gan)燥(zao)效(xiao)果的(de)(de)物(wu)料在(zai)(zai)熱(re)風作用(yong)下快(kuai)速行(xing)進(jin)(jin)(jin)(jin)(jin)排出滾(gun)(gun)(gun)筒,沒有達到干(gan)(gan)(gan)燥(zao)效(xiao)果的(de)(de)濕物(wu)料因自重而不能(neng)快(kuai)速行(xing)進(jin)(jin)(jin)(jin)(jin),物(wu)料在(zai)(zai)此(ci)矩形抄(chao)板內(nei)進(jin)(jin)(jin)(jin)(jin)行(xing)充分(fen)干(gan)(gan)(gan)燥(zao),由(you)此(ci)完成干(gan)(gan)(gan)燥(zao)目的(de)(de)。
