產品結構
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)體(ti)部分(fen)由三個同(tong)軸水平放置的內、中(zhong)、外筒(tong)套疊組成(cheng),這就使筒(tong)體(ti)的截面得(de)到充分(fen)的利用(yong)。其筒(tong)體(ti)外形總(zong)長度約為與之相當(dang)的單筒(tong)的30-35%。從而大幅度地(di)減少(shao)占地(di)面積(ji)和廠房建筑面積(ji)。
該機(ji)(ji)的支承(cheng)裝置,是在外筒上輪(lun)(lun)帶與托輪(lun)(lun)支承(cheng),由電機(ji)(ji)直(zhi)接帶動托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶摩擦(ca),使筒體(ti)轉動。該機(ji)(ji)總體(ti)結構緊湊、合理、簡(jian)單,為便于磨損件的檢(jian)修更換(huan),在中(zhong)間設(she)計成軸向剖分式,用螺栓固(gu)定連接。
工作原理
物(wu)料(liao)(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)(liao)裝置進(jin)入回轉滾筒的(de)(de)內層(ceng)(ceng)(ceng),實(shi)現(xian)順流烘干(gan),物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)的(de)(de)抄(chao)板下不(bu)斷抄(chao)起、散落呈螺旋行(xing)(xing)(xing)進(jin)式實(shi)現(xian)熱(re)(re)交(jiao)換,物(wu)料(liao)(liao)(liao)(liao)(liao)移動至內層(ceng)(ceng)(ceng)的(de)(de)另一端進(jin)入中層(ceng)(ceng)(ceng),進(jin)行(xing)(xing)(xing)逆流烘干(gan),物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)不(bu)斷地被(bei)反(fan)復揚進(jin),呈進(jin)兩步(bu)(bu)退(tui)一步(bu)(bu)的(de)(de)行(xing)(xing)(xing)進(jin)方式,物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)既(ji)充分吸(xi)收內層(ceng)(ceng)(ceng)滾筒散發的(de)(de)熱(re)(re)量,又(you)吸(xi)收中層(ceng)(ceng)(ceng)滾筒的(de)(de)熱(re)(re)量,同時又(you)延(yan)長了干(gan)燥(zao)(zao)時間,物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)達(da)(da)到(dao)干(gan)燥(zao)(zao)狀態。物(wu)料(liao)(liao)(liao)(liao)(liao)行(xing)(xing)(xing)至中層(ceng)(ceng)(ceng)另一端而落入外(wai)層(ceng)(ceng)(ceng),物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)(ceng)滾筒內呈矩形多回路方式行(xing)(xing)(xing)進(jin),達(da)(da)到(dao)干(gan)燥(zao)(zao)效果(guo)的(de)(de)物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)熱(re)(re)風作用下快速(su)行(xing)(xing)(xing)進(jin)排出滾筒,沒有達(da)(da)到(dao)干(gan)燥(zao)(zao)效果(guo)的(de)(de)濕(shi)物(wu)料(liao)(liao)(liao)(liao)(liao)因自重而不(bu)能(neng)快速(su)行(xing)(xing)(xing)進(jin),物(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)矩形抄(chao)板內進(jin)行(xing)(xing)(xing)充分干(gan)燥(zao)(zao),由此(ci)完成干(gan)燥(zao)(zao)目的(de)(de)。
