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)(tong)體部(bu)分(fen)由三個同軸(zhou)水平放置的內(nei)、中、外筒(tong)(tong)(tong)套疊組成,這就使(shi)筒(tong)(tong)(tong)體的截(jie)面(mian)(mian)得到充分(fen)的利用。其筒(tong)(tong)(tong)體外形(xing)總長度約為與之相當的單筒(tong)(tong)(tong)的30-35%。從而大幅度地減少(shao)占(zhan)地面(mian)(mian)積和廠房建(jian)筑面(mian)(mian)積。
該機(ji)(ji)的支承(cheng)裝(zhuang)置,是在(zai)外(wai)筒上(shang)輪(lun)帶(dai)與(yu)托輪(lun)支承(cheng),由電機(ji)(ji)直接(jie)帶(dai)動托輪(lun)。通(tong)過托輪(lun)與(yu)輪(lun)帶(dai)摩擦,使筒體轉動。該機(ji)(ji)總(zong)體結構緊湊、合(he)理、簡單,為便于磨損件的檢修更換(huan),在(zai)中間設計成(cheng)軸向剖分式(shi),用螺栓固定連(lian)接(jie)。
工作原理(li)
物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝置進(jin)(jin)入回轉(zhuan)滾(gun)(gun)筒(tong)(tong)的(de)(de)(de)內(nei)層(ceng),實(shi)現順流烘干(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在內(nei)層(ceng)的(de)(de)(de)抄(chao)板(ban)下不(bu)斷(duan)抄(chao)起、散(san)落呈螺旋(xuan)行(xing)進(jin)(jin)式實(shi)現熱交換,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移(yi)動至(zhi)內(nei)層(ceng)的(de)(de)(de)另一(yi)(yi)端(duan)進(jin)(jin)入中層(ceng),進(jin)(jin)行(xing)逆流烘干(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在中層(ceng)不(bu)斷(duan)地被反復揚進(jin)(jin),呈進(jin)(jin)兩步退(tui)一(yi)(yi)步的(de)(de)(de)行(xing)進(jin)(jin)方式,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在中層(ceng)既充(chong)分(fen)吸(xi)收內(nei)層(ceng)滾(gun)(gun)筒(tong)(tong)散(san)發的(de)(de)(de)熱量,又吸(xi)收中層(ceng)滾(gun)(gun)筒(tong)(tong)的(de)(de)(de)熱量,同時(shi)又延長了干(gan)(gan)(gan)燥(zao)(zao)時(shi)間,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在此(ci)達(da)到干(gan)(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)至(zhi)中層(ceng)另一(yi)(yi)端(duan)而落入外層(ceng),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在外層(ceng)滾(gun)(gun)筒(tong)(tong)內(nei)呈矩形多回路方式行(xing)進(jin)(jin),達(da)到干(gan)(gan)(gan)燥(zao)(zao)效(xiao)果的(de)(de)(de)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在熱風作用下快速行(xing)進(jin)(jin)排出滾(gun)(gun)筒(tong)(tong),沒有達(da)到干(gan)(gan)(gan)燥(zao)(zao)效(xiao)果的(de)(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因自重(zhong)而不(bu)能快速行(xing)進(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在此(ci)矩形抄(chao)板(ban)內(nei)進(jin)(jin)行(xing)充(chong)分(fen)干(gan)(gan)(gan)燥(zao)(zao),由此(ci)完成干(gan)(gan)(gan)燥(zao)(zao)目的(de)(de)(de)。
