產(chan)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(ti)部分由三個同軸水平(ping)放(fang)置的(de)(de)內、中、外(wai)筒(tong)套疊組成(cheng),這就使筒(tong)體(ti)的(de)(de)截面得到(dao)充分的(de)(de)利用。其(qi)筒(tong)體(ti)外(wai)形總長度(du)約(yue)為與之相(xiang)當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度(du)地減少占(zhan)地面積和(he)廠房建筑面積。
該機的(de)支承裝置(zhi),是在(zai)外筒上輪(lun)(lun)帶(dai)(dai)(dai)與托(tuo)輪(lun)(lun)支承,由電機直接帶(dai)(dai)(dai)動托(tuo)輪(lun)(lun)。通過(guo)托(tuo)輪(lun)(lun)與輪(lun)(lun)帶(dai)(dai)(dai)摩(mo)擦(ca),使筒體轉動。該機總體結構緊湊(cou)、合(he)理、簡單,為便于磨(mo)損件的(de)檢修(xiu)更換,在(zai)中間設計(ji)成軸向剖分式,用螺栓(shuan)固定連接。
工作(zuo)原理(li)
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)由(you)供(gong)料(liao)(liao)(liao)裝(zhuang)置進(jin)入回轉(zhuan)滾(gun)筒(tong)(tong)的(de)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng),實現順(shun)流(liu)烘(hong)干,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)抄(chao)板下不(bu)(bu)斷抄(chao)起、散落呈螺旋行(xing)進(jin)式實現熱交換,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)移(yi)動至(zhi)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)另(ling)(ling)一(yi)(yi)端(duan)進(jin)入中層(ceng)(ceng)(ceng)(ceng),進(jin)行(xing)逆流(liu)烘(hong)干,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)(ceng)不(bu)(bu)斷地被(bei)反復揚(yang)進(jin),呈進(jin)兩步退一(yi)(yi)步的(de)行(xing)進(jin)方(fang)式,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)(ceng)既充分吸收內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)散發的(de)熱量,又(you)吸收中層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)熱量,同時(shi)又(you)延長了(le)干燥(zao)時(shi)間,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此(ci)(ci)達到干燥(zao)狀態(tai)。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)至(zhi)中層(ceng)(ceng)(ceng)(ceng)另(ling)(ling)一(yi)(yi)端(duan)而落入外(wai)層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)(nei)呈矩形多回路方(fang)式行(xing)進(jin),達到干燥(zao)效(xiao)果(guo)的(de)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)熱風(feng)作用(yong)下快速(su)行(xing)進(jin)排出滾(gun)筒(tong)(tong),沒有達到干燥(zao)效(xiao)果(guo)的(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)因自(zi)重而不(bu)(bu)能快速(su)行(xing)進(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此(ci)(ci)矩形抄(chao)板內(nei)(nei)進(jin)行(xing)充分干燥(zao),由(you)此(ci)(ci)完成(cheng)干燥(zao)目(mu)的(de)。
