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(gan)機筒(tong)(tong)(tong)體部分(fen)由三個同軸水平放置的(de)內、中(zhong)、外筒(tong)(tong)(tong)套(tao)疊組(zu)成(cheng),這(zhe)就(jiu)使(shi)筒(tong)(tong)(tong)體的(de)截面(mian)得(de)到充分(fen)的(de)利用。其筒(tong)(tong)(tong)體外形總長度(du)約(yue)為與之相當的(de)單筒(tong)(tong)(tong)的(de)30-35%。從而大幅度(du)地減少占地面(mian)積和廠房建筑(zhu)面(mian)積。
該機(ji)的(de)支承裝置,是(shi)在(zai)外筒上(shang)輪(lun)(lun)帶與(yu)托輪(lun)(lun)支承,由電機(ji)直接(jie)帶動托輪(lun)(lun)。通過托輪(lun)(lun)與(yu)輪(lun)(lun)帶摩擦,使筒體轉(zhuan)動。該機(ji)總體結(jie)構緊湊、合(he)理、簡單,為便(bian)于磨損件的(de)檢修更換,在(zai)中間設(she)計成軸向剖分式(shi),用螺栓固定連接(jie)。
工(gong)作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)由供(gong)料(liao)(liao)裝(zhuang)置進(jin)(jin)(jin)入回(hui)轉滾(gun)(gun)筒(tong)的(de)(de)內(nei)層(ceng)(ceng)(ceng),實現(xian)順(shun)流烘(hong)干,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)的(de)(de)抄板(ban)下(xia)(xia)不(bu)斷抄起、散落(luo)呈螺旋行(xing)進(jin)(jin)(jin)式實現(xian)熱(re)交換,物(wu)(wu)(wu)(wu)料(liao)(liao)移動至(zhi)內(nei)層(ceng)(ceng)(ceng)的(de)(de)另(ling)一端進(jin)(jin)(jin)入中層(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)逆流烘(hong)干,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)不(bu)斷地(di)被反復(fu)揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩步退一步的(de)(de)行(xing)進(jin)(jin)(jin)方式,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)既充分(fen)吸收(shou)內(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散發的(de)(de)熱(re)量(liang),又吸收(shou)中層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)(de)熱(re)量(liang),同時又延長了干燥(zao)(zao)時間,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)達(da)到(dao)干燥(zao)(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)至(zhi)中層(ceng)(ceng)(ceng)另(ling)一端而落(luo)入外(wai)層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)呈矩(ju)形多回(hui)路方式行(xing)進(jin)(jin)(jin),達(da)到(dao)干燥(zao)(zao)效果(guo)的(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)熱(re)風作用下(xia)(xia)快(kuai)速行(xing)進(jin)(jin)(jin)排出(chu)滾(gun)(gun)筒(tong),沒有達(da)到(dao)干燥(zao)(zao)效果(guo)的(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)因自重而不(bu)能快(kuai)速行(xing)進(jin)(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)矩(ju)形抄板(ban)內(nei)進(jin)(jin)(jin)行(xing)充分(fen)干燥(zao)(zao),由此(ci)完成干燥(zao)(zao)目的(de)(de)。
