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)體部分由三個(ge)同軸水平放置的內、中、外筒(tong)套(tao)疊組成,這就(jiu)使筒(tong)體的截面(mian)得(de)到充(chong)分的利用(yong)。其筒(tong)體外形總長度約為與之相當的單筒(tong)的30-35%。從而大幅度地(di)減(jian)少(shao)占地(di)面(mian)積(ji)和(he)廠房建(jian)筑(zhu)面(mian)積(ji)。
該機(ji)的支承(cheng)裝置,是在外筒上輪(lun)(lun)帶與(yu)托(tuo)輪(lun)(lun)支承(cheng),由電機(ji)直接帶動托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與(yu)輪(lun)(lun)帶摩擦,使(shi)筒體轉動。該機(ji)總體結構緊湊(cou)、合理、簡(jian)單,為(wei)便于磨損(sun)件的檢修更換,在中(zhong)間(jian)設計成軸向剖(pou)分式,用(yong)螺栓固(gu)定連接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)(liao)(liao)裝置進(jin)入回(hui)轉滾(gun)(gun)筒(tong)的(de)(de)內(nei)(nei)層(ceng),實現(xian)順(shun)流烘干(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)內(nei)(nei)層(ceng)的(de)(de)抄板(ban)下不(bu)斷(duan)抄起、散落(luo)呈螺旋行(xing)進(jin)式實現(xian)熱(re)交換,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)移動至內(nei)(nei)層(ceng)的(de)(de)另(ling)一端進(jin)入中(zhong)(zhong)層(ceng),進(jin)行(xing)逆流烘干(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)不(bu)斷(duan)地(di)被(bei)反復揚進(jin),呈進(jin)兩步退一步的(de)(de)行(xing)進(jin)方(fang)式,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)既(ji)充(chong)分(fen)吸收內(nei)(nei)層(ceng)滾(gun)(gun)筒(tong)散發的(de)(de)熱(re)量,又吸收中(zhong)(zhong)層(ceng)滾(gun)(gun)筒(tong)的(de)(de)熱(re)量,同時(shi)又延長了干(gan)燥(zao)(zao)時(shi)間,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)此(ci)達到(dao)干(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)行(xing)至中(zhong)(zhong)層(ceng)另(ling)一端而(er)落(luo)入外層(ceng),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)外層(ceng)滾(gun)(gun)筒(tong)內(nei)(nei)呈矩形多(duo)回(hui)路(lu)方(fang)式行(xing)進(jin),達到(dao)干(gan)燥(zao)(zao)效果的(de)(de)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)熱(re)風作用下快(kuai)速(su)行(xing)進(jin)排出滾(gun)(gun)筒(tong),沒有達到(dao)干(gan)燥(zao)(zao)效果的(de)(de)濕(shi)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)因自(zi)重(zhong)而(er)不(bu)能快(kuai)速(su)行(xing)進(jin),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)此(ci)矩形抄板(ban)內(nei)(nei)進(jin)行(xing)充(chong)分(fen)干(gan)燥(zao)(zao),由此(ci)完成(cheng)干(gan)燥(zao)(zao)目(mu)的(de)(de)。
