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(hong)干機筒(tong)體部分(fen)由(you)三個同(tong)軸水平放置的(de)(de)內、中、外筒(tong)套(tao)疊(die)組(zu)成,這就使(shi)筒(tong)體的(de)(de)截面(mian)得到充分(fen)的(de)(de)利用(yong)。其筒(tong)體外形總長度(du)約為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度(du)地減少占(zhan)地面(mian)積和廠房(fang)建筑(zhu)面(mian)積。
該機(ji)的支承裝(zhuang)置,是在外筒上輪(lun)帶(dai)(dai)與(yu)托(tuo)(tuo)輪(lun)支承,由電機(ji)直接帶(dai)(dai)動托(tuo)(tuo)輪(lun)。通過托(tuo)(tuo)輪(lun)與(yu)輪(lun)帶(dai)(dai)摩(mo)擦,使筒體(ti)(ti)轉動。該機(ji)總體(ti)(ti)結構緊湊(cou)、合理(li)、簡單,為(wei)便于磨(mo)損件的檢修更換,在中間設計成軸向剖分(fen)式(shi),用螺栓固(gu)定連接。
工作原理(li)
物料(liao)由(you)供(gong)料(liao)裝置(zhi)進(jin)(jin)(jin)入回(hui)轉滾(gun)筒的內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng),實現順流烘干(gan)(gan)(gan)(gan)(gan),物料(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的抄(chao)板(ban)下不(bu)斷抄(chao)起、散落(luo)呈(cheng)螺旋行(xing)(xing)進(jin)(jin)(jin)式(shi)實現熱(re)交(jiao)換,物料(liao)移動至(zhi)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的另一(yi)(yi)端(duan)進(jin)(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)(xing)逆流烘干(gan)(gan)(gan)(gan)(gan),物料(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)不(bu)斷地(di)被反復揚進(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)兩步退一(yi)(yi)步的行(xing)(xing)進(jin)(jin)(jin)方(fang)式(shi),物料(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)既充(chong)(chong)分吸(xi)收內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒散發的熱(re)量(liang),又吸(xi)收中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒的熱(re)量(liang),同時又延長了干(gan)(gan)(gan)(gan)(gan)燥(zao)時間,物料(liao)在(zai)此(ci)達到干(gan)(gan)(gan)(gan)(gan)燥(zao)狀態。物料(liao)行(xing)(xing)至(zhi)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)另一(yi)(yi)端(duan)而落(luo)入外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng),物料(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒內(nei)呈(cheng)矩(ju)形(xing)多(duo)回(hui)路(lu)方(fang)式(shi)行(xing)(xing)進(jin)(jin)(jin),達到干(gan)(gan)(gan)(gan)(gan)燥(zao)效果的物料(liao)在(zai)熱(re)風作用下快(kuai)速行(xing)(xing)進(jin)(jin)(jin)排出滾(gun)筒,沒有達到干(gan)(gan)(gan)(gan)(gan)燥(zao)效果的濕物料(liao)因(yin)自重而不(bu)能(neng)快(kuai)速行(xing)(xing)進(jin)(jin)(jin),物料(liao)在(zai)此(ci)矩(ju)形(xing)抄(chao)板(ban)內(nei)進(jin)(jin)(jin)行(xing)(xing)充(chong)(chong)分干(gan)(gan)(gan)(gan)(gan)燥(zao),由(you)此(ci)完(wan)成干(gan)(gan)(gan)(gan)(gan)燥(zao)目(mu)的。
