產(chan)品結構(gou)
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)干機(ji)筒(tong)(tong)體部分由三個同軸(zhou)水(shui)平(ping)放置的(de)內(nei)、中、外筒(tong)(tong)套(tao)疊組(zu)成,這就(jiu)使筒(tong)(tong)體的(de)截面(mian)得到充分的(de)利用。其筒(tong)(tong)體外形(xing)總長度約為與之相當的(de)單筒(tong)(tong)的(de)30-35%。從而大幅度地減少占地面(mian)積和(he)廠(chang)房建(jian)筑面(mian)積。
該機(ji)的支承裝置,是在(zai)外筒上輪(lun)(lun)(lun)帶(dai)與托輪(lun)(lun)(lun)支承,由電機(ji)直接帶(dai)動托輪(lun)(lun)(lun)。通過(guo)托輪(lun)(lun)(lun)與輪(lun)(lun)(lun)帶(dai)摩擦,使筒體轉動。該機(ji)總體結(jie)構緊湊、合理、簡單,為便于磨損件的檢修(xiu)更換,在(zai)中間設計(ji)成軸(zhou)向剖(pou)分式,用(yong)螺栓固定(ding)連接。
工作原理
物(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置(zhi)進(jin)(jin)(jin)入回轉(zhuan)滾(gun)筒(tong)(tong)的(de)內(nei)層,實現(xian)順(shun)流烘(hong)干(gan)(gan),物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)內(nei)層的(de)抄板下不斷抄起、散落(luo)(luo)呈螺旋行(xing)(xing)進(jin)(jin)(jin)式實現(xian)熱交換(huan),物(wu)(wu)料(liao)(liao)移動至(zhi)內(nei)層的(de)另一端進(jin)(jin)(jin)入中(zhong)(zhong)層,進(jin)(jin)(jin)行(xing)(xing)逆流烘(hong)干(gan)(gan),物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)中(zhong)(zhong)層不斷地(di)被反(fan)復揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩步退一步的(de)行(xing)(xing)進(jin)(jin)(jin)方(fang)式,物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)中(zhong)(zhong)層既充分吸收內(nei)層滾(gun)筒(tong)(tong)散發(fa)的(de)熱量,又(you)吸收中(zhong)(zhong)層滾(gun)筒(tong)(tong)的(de)熱量,同時又(you)延長了干(gan)(gan)燥(zao)(zao)時間(jian),物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)此(ci)達到(dao)(dao)干(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)料(liao)(liao)行(xing)(xing)至(zhi)中(zhong)(zhong)層另一端而(er)落(luo)(luo)入外(wai)層,物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)外(wai)層滾(gun)筒(tong)(tong)內(nei)呈矩形多回路方(fang)式行(xing)(xing)進(jin)(jin)(jin),達到(dao)(dao)干(gan)(gan)燥(zao)(zao)效(xiao)果(guo)的(de)物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)熱風(feng)作(zuo)用下快速(su)行(xing)(xing)進(jin)(jin)(jin)排出滾(gun)筒(tong)(tong),沒有達到(dao)(dao)干(gan)(gan)燥(zao)(zao)效(xiao)果(guo)的(de)濕物(wu)(wu)料(liao)(liao)因自重(zhong)而(er)不能快速(su)行(xing)(xing)進(jin)(jin)(jin),物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)此(ci)矩形抄板內(nei)進(jin)(jin)(jin)行(xing)(xing)充分干(gan)(gan)燥(zao)(zao),由此(ci)完成干(gan)(gan)燥(zao)(zao)目(mu)的(de)。
