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。
烘干機筒體部分由(you)三(san)個同軸水(shui)平放置的(de)(de)(de)內、中(zhong)、外筒套疊組成(cheng),這就(jiu)使筒體的(de)(de)(de)截面得到充分的(de)(de)(de)利用。其筒體外形總長度(du)約為與(yu)之相當的(de)(de)(de)單(dan)筒的(de)(de)(de)30-35%。從而大(da)幅(fu)度(du)地減少(shao)占地面積和(he)廠(chang)房(fang)建筑面積。
該(gai)機的支(zhi)(zhi)承裝置,是在(zai)外筒(tong)上(shang)輪(lun)帶與托(tuo)輪(lun)支(zhi)(zhi)承,由電機直接(jie)帶動托(tuo)輪(lun)。通(tong)過托(tuo)輪(lun)與輪(lun)帶摩擦,使筒(tong)體(ti)轉動。該(gai)機總(zong)體(ti)結構緊湊、合理、簡單,為便于(yu)磨(mo)損件的檢修(xiu)更換,在(zai)中間設計成(cheng)軸向剖(pou)分式,用螺栓固定連接(jie)。
工作原理
物(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)(jin)入(ru)(ru)回(hui)轉滾筒(tong)的內層(ceng)(ceng)(ceng),實現順流(liu)烘(hong)干(gan)(gan)(gan)(gan),物(wu)料(liao)(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)的抄(chao)板下(xia)不斷抄(chao)起、散落呈(cheng)螺旋行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)式(shi)實現熱(re)交換,物(wu)料(liao)(liao)移動(dong)至內層(ceng)(ceng)(ceng)的另(ling)一端進(jin)(jin)(jin)(jin)入(ru)(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)行(xing)(xing)(xing)逆流(liu)烘(hong)干(gan)(gan)(gan)(gan),物(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不斷地被反復(fu)揚進(jin)(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)(jin)兩(liang)步退(tui)一步的行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)方式(shi),物(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充(chong)分吸(xi)收(shou)內層(ceng)(ceng)(ceng)滾筒(tong)散發的熱(re)量(liang),又吸(xi)收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)滾筒(tong)的熱(re)量(liang),同時(shi)又延長了干(gan)(gan)(gan)(gan)燥(zao)時(shi)間,物(wu)料(liao)(liao)在(zai)(zai)此達(da)到(dao)干(gan)(gan)(gan)(gan)燥(zao)狀態。物(wu)料(liao)(liao)行(xing)(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)另(ling)一端而落入(ru)(ru)外層(ceng)(ceng)(ceng),物(wu)料(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)滾筒(tong)內呈(cheng)矩形(xing)多回(hui)路方式(shi)行(xing)(xing)(xing)進(jin)(jin)(jin)(jin),達(da)到(dao)干(gan)(gan)(gan)(gan)燥(zao)效果的物(wu)料(liao)(liao)在(zai)(zai)熱(re)風作用下(xia)快速行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)排出滾筒(tong),沒有(you)達(da)到(dao)干(gan)(gan)(gan)(gan)燥(zao)效果的濕物(wu)料(liao)(liao)因自重而不能快速行(xing)(xing)(xing)進(jin)(jin)(jin)(jin),物(wu)料(liao)(liao)在(zai)(zai)此矩形(xing)抄(chao)板內進(jin)(jin)(jin)(jin)行(xing)(xing)(xing)充(chong)分干(gan)(gan)(gan)(gan)燥(zao),由此完成干(gan)(gan)(gan)(gan)燥(zao)目的。
