產品結構
大型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(hong)干(gan)機筒(tong)(tong)體部分由三(san)個同軸水平放置的(de)(de)內、中、外筒(tong)(tong)套疊組成,這就使筒(tong)(tong)體的(de)(de)截(jie)面(mian)得到充分的(de)(de)利用。其筒(tong)(tong)體外形(xing)總長度(du)約為與之相當的(de)(de)單筒(tong)(tong)的(de)(de)30-35%。從而大幅度(du)地(di)減(jian)少占地(di)面(mian)積和廠房建筑面(mian)積。
該機的支(zhi)承裝置,是在外(wai)筒(tong)上輪帶(dai)(dai)與(yu)托輪支(zhi)承,由電機直接帶(dai)(dai)動托輪。通過托輪與(yu)輪帶(dai)(dai)摩(mo)擦,使筒(tong)體轉動。該機總(zong)體結構緊湊(cou)、合(he)理、簡單(dan),為便于磨損件的檢(jian)修更換(huan),在中(zhong)間設計成軸向剖分(fen)式(shi),用螺栓(shuan)固(gu)定連(lian)接。
工作原理
物(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置進(jin)(jin)入回(hui)轉滾(gun)筒(tong)的(de)(de)(de)內層(ceng)(ceng),實現(xian)(xian)順流烘干(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)在內層(ceng)(ceng)的(de)(de)(de)抄(chao)(chao)板(ban)下不斷抄(chao)(chao)起、散落(luo)呈(cheng)螺(luo)旋行(xing)(xing)(xing)進(jin)(jin)式實現(xian)(xian)熱(re)交換,物(wu)(wu)料(liao)(liao)(liao)移動至(zhi)(zhi)內層(ceng)(ceng)的(de)(de)(de)另一(yi)端進(jin)(jin)入中(zhong)層(ceng)(ceng),進(jin)(jin)行(xing)(xing)(xing)逆流烘干(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)不斷地被(bei)反復揚進(jin)(jin),呈(cheng)進(jin)(jin)兩步退(tui)一(yi)步的(de)(de)(de)行(xing)(xing)(xing)進(jin)(jin)方(fang)式,物(wu)(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)既充(chong)(chong)分(fen)吸收內層(ceng)(ceng)滾(gun)筒(tong)散發的(de)(de)(de)熱(re)量(liang),又吸收中(zhong)層(ceng)(ceng)滾(gun)筒(tong)的(de)(de)(de)熱(re)量(liang),同時又延長了(le)干(gan)(gan)燥時間,物(wu)(wu)料(liao)(liao)(liao)在此達到干(gan)(gan)燥狀態。物(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)(xing)至(zhi)(zhi)中(zhong)層(ceng)(ceng)另一(yi)端而落(luo)入外層(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)在外層(ceng)(ceng)滾(gun)筒(tong)內呈(cheng)矩(ju)形(xing)多回(hui)路方(fang)式行(xing)(xing)(xing)進(jin)(jin),達到干(gan)(gan)燥效果(guo)的(de)(de)(de)物(wu)(wu)料(liao)(liao)(liao)在熱(re)風作(zuo)用(yong)下快速行(xing)(xing)(xing)進(jin)(jin)排出(chu)滾(gun)筒(tong),沒有達到干(gan)(gan)燥效果(guo)的(de)(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)因自重(zhong)而不能快速行(xing)(xing)(xing)進(jin)(jin),物(wu)(wu)料(liao)(liao)(liao)在此矩(ju)形(xing)抄(chao)(chao)板(ban)內進(jin)(jin)行(xing)(xing)(xing)充(chong)(chong)分(fen)干(gan)(gan)燥,由此完(wan)成干(gan)(gan)燥目的(de)(de)(de)。
