產品結構
大型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)(ti)部分由三個同軸水(shui)平放置的(de)(de)內、中、外(wai)(wai)筒(tong)套疊組成,這就使筒(tong)體(ti)(ti)的(de)(de)截面(mian)得到充分的(de)(de)利(li)用。其筒(tong)體(ti)(ti)外(wai)(wai)形總長(chang)度約為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度地(di)減少占地(di)面(mian)積(ji)和廠(chang)房建筑面(mian)積(ji)。
該(gai)機的(de)支承裝置,是(shi)在外(wai)筒上(shang)輪(lun)(lun)(lun)帶(dai)(dai)與(yu)托輪(lun)(lun)(lun)支承,由電機直接帶(dai)(dai)動托輪(lun)(lun)(lun)。通過托輪(lun)(lun)(lun)與(yu)輪(lun)(lun)(lun)帶(dai)(dai)摩擦,使筒體轉動。該(gai)機總(zong)體結構(gou)緊湊、合理(li)、簡(jian)單,為便(bian)于磨損(sun)件的(de)檢(jian)修更換(huan),在中(zhong)間設計成軸向剖分式,用螺栓固定連接。
工(gong)作原理
物(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝(zhuang)置進(jin)(jin)(jin)入(ru)回轉滾(gun)(gun)筒(tong)的內(nei)層(ceng)(ceng),實(shi)現順(shun)流(liu)烘干,物(wu)(wu)料(liao)(liao)在內(nei)層(ceng)(ceng)的抄板下(xia)不斷抄起、散(san)落呈螺(luo)旋(xuan)行(xing)進(jin)(jin)(jin)式(shi)實(shi)現熱(re)(re)交換(huan),物(wu)(wu)料(liao)(liao)移(yi)動至(zhi)內(nei)層(ceng)(ceng)的另(ling)一端進(jin)(jin)(jin)入(ru)中(zhong)(zhong)(zhong)層(ceng)(ceng),進(jin)(jin)(jin)行(xing)逆流(liu)烘干,物(wu)(wu)料(liao)(liao)在中(zhong)(zhong)(zhong)層(ceng)(ceng)不斷地被反復(fu)揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩(liang)步退一步的行(xing)進(jin)(jin)(jin)方(fang)式(shi),物(wu)(wu)料(liao)(liao)在中(zhong)(zhong)(zhong)層(ceng)(ceng)既充(chong)(chong)分吸(xi)收內(nei)層(ceng)(ceng)滾(gun)(gun)筒(tong)散(san)發(fa)的熱(re)(re)量,又吸(xi)收中(zhong)(zhong)(zhong)層(ceng)(ceng)滾(gun)(gun)筒(tong)的熱(re)(re)量,同時又延長(chang)了干燥(zao)(zao)時間,物(wu)(wu)料(liao)(liao)在此達(da)到(dao)干燥(zao)(zao)狀態。物(wu)(wu)料(liao)(liao)行(xing)至(zhi)中(zhong)(zhong)(zhong)層(ceng)(ceng)另(ling)一端而落入(ru)外層(ceng)(ceng),物(wu)(wu)料(liao)(liao)在外層(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)呈矩形多回路方(fang)式(shi)行(xing)進(jin)(jin)(jin),達(da)到(dao)干燥(zao)(zao)效果的物(wu)(wu)料(liao)(liao)在熱(re)(re)風作用下(xia)快速行(xing)進(jin)(jin)(jin)排出滾(gun)(gun)筒(tong),沒有達(da)到(dao)干燥(zao)(zao)效果的濕物(wu)(wu)料(liao)(liao)因自(zi)重而不能快速行(xing)進(jin)(jin)(jin),物(wu)(wu)料(liao)(liao)在此矩形抄板內(nei)進(jin)(jin)(jin)行(xing)充(chong)(chong)分干燥(zao)(zao),由此完成干燥(zao)(zao)目(mu)的。
