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)體(ti)(ti)(ti)部分(fen)由三個同軸水平放置的(de)內(nei)、中、外(wai)筒(tong)套疊組成,這就使筒(tong)體(ti)(ti)(ti)的(de)截面(mian)(mian)得到充分(fen)的(de)利用。其(qi)筒(tong)體(ti)(ti)(ti)外(wai)形(xing)總長度約為與(yu)之相當(dang)的(de)單(dan)筒(tong)的(de)30-35%。從而(er)大(da)幅度地減(jian)少占(zhan)地面(mian)(mian)積和廠房(fang)建(jian)筑(zhu)面(mian)(mian)積。
該機的(de)支(zhi)(zhi)承裝置,是在外筒上輪(lun)帶(dai)與(yu)托輪(lun)支(zhi)(zhi)承,由電機直接帶(dai)動托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶(dai)摩擦,使筒體轉動。該機總體結構(gou)緊湊、合(he)理、簡單,為便(bian)于磨損件的(de)檢(jian)修更換,在中間(jian)設計(ji)成(cheng)軸向剖分式,用螺栓固定連接。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置(zhi)進(jin)(jin)入(ru)回(hui)轉滾(gun)(gun)筒(tong)的(de)內(nei)層(ceng)(ceng),實現順流烘(hong)干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)的(de)抄板(ban)下不斷抄起、散落呈(cheng)(cheng)螺旋行(xing)(xing)進(jin)(jin)式實現熱(re)(re)交換,物(wu)(wu)(wu)(wu)料(liao)(liao)移動至內(nei)層(ceng)(ceng)的(de)另一端(duan)進(jin)(jin)入(ru)中(zhong)層(ceng)(ceng),進(jin)(jin)行(xing)(xing)逆流烘(hong)干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)不斷地被反復揚進(jin)(jin),呈(cheng)(cheng)進(jin)(jin)兩步退一步的(de)行(xing)(xing)進(jin)(jin)方(fang)式,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)既充(chong)分吸收內(nei)層(ceng)(ceng)滾(gun)(gun)筒(tong)散發(fa)的(de)熱(re)(re)量,又吸收中(zhong)層(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)熱(re)(re)量,同時(shi)又延長了干(gan)燥時(shi)間(jian),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)達到干(gan)燥狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)至中(zhong)層(ceng)(ceng)另一端(duan)而落入(ru)外層(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)外層(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)呈(cheng)(cheng)矩(ju)形多(duo)回(hui)路(lu)方(fang)式行(xing)(xing)進(jin)(jin),達到干(gan)燥效果(guo)的(de)物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)熱(re)(re)風(feng)作用下快(kuai)速行(xing)(xing)進(jin)(jin)排出滾(gun)(gun)筒(tong),沒有達到干(gan)燥效果(guo)的(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)因(yin)自重而不能(neng)快(kuai)速行(xing)(xing)進(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)矩(ju)形抄板(ban)內(nei)進(jin)(jin)行(xing)(xing)充(chong)分干(gan)燥,由此(ci)完(wan)成(cheng)干(gan)燥目的(de)。
