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)體部分由三個同軸水(shui)平放置的(de)內、中(zhong)、外(wai)筒(tong)套(tao)疊(die)組成(cheng),這就使筒(tong)體的(de)截面(mian)得到充分的(de)利(li)用。其(qi)筒(tong)體外(wai)形總長(chang)度約(yue)為(wei)與之(zhi)相(xiang)當的(de)單筒(tong)的(de)30-35%。從而大幅度地減(jian)少(shao)占地面(mian)積和廠房建筑面(mian)積。
該(gai)(gai)機的(de)支承(cheng)裝置,是(shi)在外筒(tong)上輪(lun)帶(dai)與托(tuo)輪(lun)支承(cheng),由(you)電機直接帶(dai)動托(tuo)輪(lun)。通(tong)過托(tuo)輪(lun)與輪(lun)帶(dai)摩擦(ca),使筒(tong)體(ti)轉動。該(gai)(gai)機總(zong)體(ti)結構緊湊、合理、簡單(dan),為便(bian)于磨損件的(de)檢修更換,在中(zhong)間設(she)計成軸向剖分式,用螺栓固定連接。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)(liao)裝(zhuang)置進(jin)入(ru)(ru)回(hui)轉(zhuan)滾(gun)(gun)筒的內(nei)層(ceng)(ceng),實現順流(liu)烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在內(nei)層(ceng)(ceng)的抄板下不斷抄起、散(san)落呈(cheng)螺旋行(xing)進(jin)式(shi)實現熱(re)(re)交(jiao)換,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移動(dong)至(zhi)內(nei)層(ceng)(ceng)的另一(yi)端(duan)(duan)進(jin)入(ru)(ru)中(zhong)(zhong)層(ceng)(ceng),進(jin)行(xing)逆流(liu)烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)不斷地被反復(fu)揚進(jin),呈(cheng)進(jin)兩步(bu)退一(yi)步(bu)的行(xing)進(jin)方式(shi),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)既(ji)充(chong)分吸收(shou)內(nei)層(ceng)(ceng)滾(gun)(gun)筒散(san)發的熱(re)(re)量(liang),又吸收(shou)中(zhong)(zhong)層(ceng)(ceng)滾(gun)(gun)筒的熱(re)(re)量(liang),同時又延長了干(gan)燥(zao)(zao)(zao)時間(jian),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在此達到干(gan)燥(zao)(zao)(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)另一(yi)端(duan)(duan)而落入(ru)(ru)外(wai)(wai)層(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在外(wai)(wai)層(ceng)(ceng)滾(gun)(gun)筒內(nei)呈(cheng)矩形多回(hui)路方式(shi)行(xing)進(jin),達到干(gan)燥(zao)(zao)(zao)效果(guo)(guo)的物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在熱(re)(re)風作(zuo)用下快(kuai)速行(xing)進(jin)排出滾(gun)(gun)筒,沒(mei)有達到干(gan)燥(zao)(zao)(zao)效果(guo)(guo)的濕物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因自重而不能(neng)快(kuai)速行(xing)進(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在此矩形抄板內(nei)進(jin)行(xing)充(chong)分干(gan)燥(zao)(zao)(zao),由(you)此完成干(gan)燥(zao)(zao)(zao)目(mu)的。
