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(hong)干(gan)機(ji)筒(tong)(tong)體部(bu)分由三(san)個(ge)同軸水平(ping)放置的(de)內(nei)、中(zhong)、外(wai)筒(tong)(tong)套疊組(zu)成,這(zhe)就使(shi)筒(tong)(tong)體的(de)截(jie)面(mian)(mian)得(de)到充(chong)分的(de)利用。其筒(tong)(tong)體外(wai)形總長度約為與(yu)之相當(dang)的(de)單(dan)筒(tong)(tong)的(de)30-35%。從而大幅度地減少(shao)占地面(mian)(mian)積和廠房建筑(zhu)面(mian)(mian)積。
該機(ji)的支承裝置(zhi),是在外筒(tong)上輪(lun)帶(dai)與托(tuo)輪(lun)支承,由(you)電機(ji)直接帶(dai)動托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶(dai)摩擦,使筒(tong)體轉動。該機(ji)總(zong)體結構(gou)緊湊、合理(li)、簡單,為便于(yu)磨損件的檢(jian)修更換(huan),在中間設計成軸向(xiang)剖分(fen)式,用(yong)螺栓固定連(lian)接。
工作原理(li)
物(wu)(wu)料(liao)由供料(liao)裝置進(jin)(jin)(jin)(jin)(jin)(jin)(jin)入回(hui)轉(zhuan)滾(gun)(gun)筒的(de)(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實現(xian)順流烘干(gan)(gan),物(wu)(wu)料(liao)在內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)(chao)板下不(bu)斷抄(chao)(chao)起、散落呈螺旋行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)(jin)(jin)式實現(xian)熱交換,物(wu)(wu)料(liao)移動至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另(ling)一端(duan)進(jin)(jin)(jin)(jin)(jin)(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)(jin)(jin)(jin)行(xing)(xing)逆流烘干(gan)(gan),物(wu)(wu)料(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷地被反(fan)復揚進(jin)(jin)(jin)(jin)(jin)(jin)(jin),呈進(jin)(jin)(jin)(jin)(jin)(jin)(jin)兩步退一步的(de)(de)(de)行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)(jin)(jin)方(fang)式,物(wu)(wu)料(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)既(ji)充分(fen)吸收(shou)內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒散發的(de)(de)(de)熱量,又吸收(shou)中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒的(de)(de)(de)熱量,同時又延(yan)長了(le)干(gan)(gan)燥(zao)時間,物(wu)(wu)料(liao)在此達(da)到(dao)(dao)干(gan)(gan)燥(zao)狀態。物(wu)(wu)料(liao)行(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一端(duan)而(er)落入外層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)料(liao)在外層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒內(nei)呈矩(ju)形(xing)多回(hui)路方(fang)式行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)(jin)(jin),達(da)到(dao)(dao)干(gan)(gan)燥(zao)效(xiao)果的(de)(de)(de)物(wu)(wu)料(liao)在熱風作用下快速行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)(jin)(jin)排出滾(gun)(gun)筒,沒(mei)有達(da)到(dao)(dao)干(gan)(gan)燥(zao)效(xiao)果的(de)(de)(de)濕物(wu)(wu)料(liao)因自重而(er)不(bu)能快速行(xing)(xing)進(jin)(jin)(jin)(jin)(jin)(jin)(jin),物(wu)(wu)料(liao)在此矩(ju)形(xing)抄(chao)(chao)板內(nei)進(jin)(jin)(jin)(jin)(jin)(jin)(jin)行(xing)(xing)充分(fen)干(gan)(gan)燥(zao),由此完(wan)成干(gan)(gan)燥(zao)目的(de)(de)(de)。
