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)部分(fen)由(you)三個同軸(zhou)水平放置的(de)內、中(zhong)、外筒(tong)(tong)套疊組成,這就使(shi)筒(tong)(tong)體(ti)的(de)截面得(de)到充分(fen)的(de)利(li)用。其筒(tong)(tong)體(ti)外形(xing)總長度(du)約為與(yu)之相(xiang)當的(de)單筒(tong)(tong)的(de)30-35%。從而大幅度(du)地(di)減少占地(di)面積和廠房建筑面積。
該(gai)機的(de)支(zhi)承裝(zhuang)置(zhi),是在外筒上輪(lun)帶與托(tuo)(tuo)(tuo)輪(lun)支(zhi)承,由(you)電機直(zhi)接(jie)帶動托(tuo)(tuo)(tuo)輪(lun)。通(tong)過(guo)托(tuo)(tuo)(tuo)輪(lun)與輪(lun)帶摩擦,使(shi)筒體(ti)(ti)轉動。該(gai)機總體(ti)(ti)結構緊(jin)湊、合理、簡單,為(wei)便于磨損件的(de)檢修更換,在中間設計(ji)成軸向剖分式,用螺栓固定連(lian)接(jie)。
工作原理
物(wu)料(liao)由(you)供料(liao)裝置(zhi)進(jin)(jin)入回轉滾(gun)筒(tong)(tong)的內層(ceng)(ceng)(ceng),實現順流烘干(gan),物(wu)料(liao)在(zai)內層(ceng)(ceng)(ceng)的抄板下不斷抄起、散落呈(cheng)(cheng)螺旋行進(jin)(jin)式(shi)實現熱交(jiao)換,物(wu)料(liao)移(yi)動至(zhi)(zhi)內層(ceng)(ceng)(ceng)的另一端進(jin)(jin)入中層(ceng)(ceng)(ceng),進(jin)(jin)行逆(ni)流烘干(gan),物(wu)料(liao)在(zai)中層(ceng)(ceng)(ceng)不斷地被反復揚進(jin)(jin),呈(cheng)(cheng)進(jin)(jin)兩步(bu)退(tui)一步(bu)的行進(jin)(jin)方式(shi),物(wu)料(liao)在(zai)中層(ceng)(ceng)(ceng)既充(chong)(chong)分吸(xi)收(shou)內層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)散發的熱量,又(you)吸(xi)收(shou)中層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)的熱量,同時又(you)延長了(le)干(gan)燥(zao)(zao)時間(jian),物(wu)料(liao)在(zai)此達(da)到(dao)干(gan)燥(zao)(zao)狀態(tai)。物(wu)料(liao)行至(zhi)(zhi)中層(ceng)(ceng)(ceng)另一端而落入外(wai)層(ceng)(ceng)(ceng),物(wu)料(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)內呈(cheng)(cheng)矩形多回路方式(shi)行進(jin)(jin),達(da)到(dao)干(gan)燥(zao)(zao)效果的物(wu)料(liao)在(zai)熱風作用下快速(su)行進(jin)(jin)排(pai)出滾(gun)筒(tong)(tong),沒有(you)達(da)到(dao)干(gan)燥(zao)(zao)效果的濕物(wu)料(liao)因自重(zhong)而不能(neng)快速(su)行進(jin)(jin),物(wu)料(liao)在(zai)此矩形抄板內進(jin)(jin)行充(chong)(chong)分干(gan)燥(zao)(zao),由(you)此完(wan)成干(gan)燥(zao)(zao)目的。
