產品結構
三筒式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(ge)同軸(zhou)水(shui)平放置的內(nei)、中、外筒(tong)套(tao)疊組(zu)成,這就(jiu)使筒(tong)體(ti)的截面得(de)到充分(fen)的利用。其(qi)筒(tong)體(ti)外形(xing)總(zong)長度(du)(du)約為(wei)與(yu)之(zhi)相當的單筒(tong)的30-35%。從而(er)大幅度(du)(du)地(di)減(jian)少占地(di)面積和廠房建筑面積。
該機(ji)(ji)的(de)支承(cheng)裝置,是在外筒上輪(lun)(lun)帶與(yu)托輪(lun)(lun)支承(cheng),由電機(ji)(ji)直(zhi)接(jie)帶動托輪(lun)(lun)。通(tong)過托輪(lun)(lun)與(yu)輪(lun)(lun)帶摩(mo)擦,使筒體(ti)轉動。該機(ji)(ji)總體(ti)結構緊(jin)湊、合理(li)、簡單,為(wei)便于磨損(sun)件的(de)檢修更換(huan),在中間設計成軸向剖分式,用(yong)螺栓固定連(lian)接(jie)。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝(zhuang)置進(jin)(jin)入(ru)回轉滾(gun)筒(tong)的(de)(de)內層(ceng)(ceng)(ceng),實現順(shun)流烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)內層(ceng)(ceng)(ceng)的(de)(de)抄板下不(bu)斷抄起、散落呈螺(luo)旋(xuan)行(xing)(xing)進(jin)(jin)式實現熱(re)交換,物(wu)(wu)(wu)(wu)料(liao)(liao)移(yi)動至內層(ceng)(ceng)(ceng)的(de)(de)另一端進(jin)(jin)入(ru)中層(ceng)(ceng)(ceng),進(jin)(jin)行(xing)(xing)逆流烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)不(bu)斷地被(bei)反復(fu)揚(yang)進(jin)(jin),呈進(jin)(jin)兩步(bu)退一步(bu)的(de)(de)行(xing)(xing)進(jin)(jin)方式,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)既充(chong)分(fen)(fen)吸(xi)收內層(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的(de)(de)熱(re)量(liang)(liang),又吸(xi)收中層(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)(de)熱(re)量(liang)(liang),同(tong)時(shi)又延(yan)長(chang)了干(gan)燥(zao)時(shi)間,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此達(da)到干(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)至中層(ceng)(ceng)(ceng)另一端而落入(ru)外(wai)層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)滾(gun)筒(tong)內呈矩(ju)形多回路方式行(xing)(xing)進(jin)(jin),達(da)到干(gan)燥(zao)效果的(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)熱(re)風作用下快速行(xing)(xing)進(jin)(jin)排出(chu)滾(gun)筒(tong),沒(mei)有達(da)到干(gan)燥(zao)效果的(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)因自重而不(bu)能(neng)快速行(xing)(xing)進(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此矩(ju)形抄板內進(jin)(jin)行(xing)(xing)充(chong)分(fen)(fen)干(gan)燥(zao),由此完成干(gan)燥(zao)目的(de)(de)。
