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)(tong)體(ti)部(bu)分由三個同軸水平放置的內、中、外筒(tong)(tong)套疊組成,這就使筒(tong)(tong)體(ti)的截(jie)面(mian)得到充分的利用。其筒(tong)(tong)體(ti)外形(xing)總長度約為(wei)與之相當(dang)的單筒(tong)(tong)的30-35%。從(cong)而大(da)幅(fu)度地減(jian)少(shao)占地面(mian)積和廠房建筑面(mian)積。
該機(ji)(ji)的支(zhi)承裝(zhuang)置,是在外(wai)筒(tong)(tong)上輪(lun)帶與(yu)托輪(lun)支(zhi)承,由(you)電機(ji)(ji)直接(jie)帶動托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶摩擦,使(shi)筒(tong)(tong)體轉動。該機(ji)(ji)總體結(jie)構緊(jin)湊、合理、簡單,為便(bian)于(yu)磨損件的檢修(xiu)更(geng)換,在中間設計成(cheng)軸向剖分式,用(yong)螺栓固定(ding)連接(jie)。
工作原理
物(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)入回(hui)轉滾(gun)筒(tong)(tong)的(de)(de)(de)(de)(de)(de)內(nei)層,實現(xian)順流烘干(gan)(gan),物(wu)(wu)料(liao)(liao)在(zai)內(nei)層的(de)(de)(de)(de)(de)(de)抄板(ban)下不(bu)(bu)斷(duan)抄起、散落呈螺旋(xuan)行(xing)(xing)進(jin)(jin)(jin)式實現(xian)熱交(jiao)換,物(wu)(wu)料(liao)(liao)移動至內(nei)層的(de)(de)(de)(de)(de)(de)另一端進(jin)(jin)(jin)入中(zhong)(zhong)層,進(jin)(jin)(jin)行(xing)(xing)逆流烘干(gan)(gan),物(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層不(bu)(bu)斷(duan)地被(bei)反復揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩步退一步的(de)(de)(de)(de)(de)(de)行(xing)(xing)進(jin)(jin)(jin)方式,物(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層既充分吸收(shou)內(nei)層滾(gun)筒(tong)(tong)散發的(de)(de)(de)(de)(de)(de)熱量(liang),又吸收(shou)中(zhong)(zhong)層滾(gun)筒(tong)(tong)的(de)(de)(de)(de)(de)(de)熱量(liang),同時又延長了干(gan)(gan)燥(zao)時間,物(wu)(wu)料(liao)(liao)在(zai)此(ci)達到(dao)干(gan)(gan)燥(zao)狀(zhuang)態。物(wu)(wu)料(liao)(liao)行(xing)(xing)至中(zhong)(zhong)層另一端而落入外層,物(wu)(wu)料(liao)(liao)在(zai)外層滾(gun)筒(tong)(tong)內(nei)呈矩形多回(hui)路(lu)方式行(xing)(xing)進(jin)(jin)(jin),達到(dao)干(gan)(gan)燥(zao)效(xiao)果(guo)(guo)的(de)(de)(de)(de)(de)(de)物(wu)(wu)料(liao)(liao)在(zai)熱風作用下快(kuai)(kuai)速行(xing)(xing)進(jin)(jin)(jin)排出(chu)滾(gun)筒(tong)(tong),沒有(you)達到(dao)干(gan)(gan)燥(zao)效(xiao)果(guo)(guo)的(de)(de)(de)(de)(de)(de)濕物(wu)(wu)料(liao)(liao)因自重(zhong)而不(bu)(bu)能快(kuai)(kuai)速行(xing)(xing)進(jin)(jin)(jin),物(wu)(wu)料(liao)(liao)在(zai)此(ci)矩形抄板(ban)內(nei)進(jin)(jin)(jin)行(xing)(xing)充分干(gan)(gan)燥(zao),由此(ci)完(wan)成(cheng)干(gan)(gan)燥(zao)目的(de)(de)(de)(de)(de)(de)。
