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)(tong)體部分由(you)三(san)個同軸水平放置(zhi)的內、中(zhong)、外筒(tong)(tong)套疊組成,這就使筒(tong)(tong)體的截面得到(dao)充分的利用(yong)。其筒(tong)(tong)體外形總長度(du)(du)約為與之(zhi)相(xiang)當的單筒(tong)(tong)的30-35%。從(cong)而大幅度(du)(du)地(di)(di)減少占地(di)(di)面積和廠房建筑面積。
該機的(de)(de)支承裝置,是(shi)在外筒上輪帶(dai)與(yu)托(tuo)(tuo)輪支承,由電機直接帶(dai)動(dong)托(tuo)(tuo)輪。通過托(tuo)(tuo)輪與(yu)輪帶(dai)摩擦,使筒體(ti)轉動(dong)。該機總體(ti)結構(gou)緊湊、合(he)理、簡單(dan),為便于磨損件(jian)的(de)(de)檢修更(geng)換(huan),在中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)(liao)由供(gong)料(liao)(liao)(liao)裝置進(jin)(jin)入回轉滾(gun)(gun)筒(tong)的(de)(de)(de)內(nei)(nei)(nei)層(ceng)(ceng),實(shi)(shi)現(xian)順流(liu)烘干,物(wu)(wu)料(liao)(liao)(liao)在(zai)內(nei)(nei)(nei)層(ceng)(ceng)的(de)(de)(de)抄(chao)(chao)(chao)板(ban)(ban)下不(bu)(bu)斷抄(chao)(chao)(chao)起(qi)、散落呈(cheng)螺旋(xuan)行(xing)進(jin)(jin)式(shi)實(shi)(shi)現(xian)熱交(jiao)換,物(wu)(wu)料(liao)(liao)(liao)移動至內(nei)(nei)(nei)層(ceng)(ceng)的(de)(de)(de)另(ling)一端(duan)進(jin)(jin)入中(zhong)層(ceng)(ceng),進(jin)(jin)行(xing)逆流(liu)烘干,物(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)不(bu)(bu)斷地被反(fan)復揚進(jin)(jin),呈(cheng)進(jin)(jin)兩(liang)步(bu)退一步(bu)的(de)(de)(de)行(xing)進(jin)(jin)方(fang)式(shi),物(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)既(ji)充分吸收內(nei)(nei)(nei)層(ceng)(ceng)滾(gun)(gun)筒(tong)散發(fa)的(de)(de)(de)熱量,又吸收中(zhong)層(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)(de)(de)熱量,同(tong)時又延長(chang)了干燥(zao)時間(jian),物(wu)(wu)料(liao)(liao)(liao)在(zai)此(ci)達(da)到(dao)干燥(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)另(ling)一端(duan)而落入外層(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)在(zai)外層(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)(nei)(nei)呈(cheng)矩形多(duo)回路方(fang)式(shi)行(xing)進(jin)(jin),達(da)到(dao)干燥(zao)效果的(de)(de)(de)物(wu)(wu)料(liao)(liao)(liao)在(zai)熱風作用下快(kuai)速(su)行(xing)進(jin)(jin)排出滾(gun)(gun)筒(tong),沒有達(da)到(dao)干燥(zao)效果的(de)(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)因自重而不(bu)(bu)能快(kuai)速(su)行(xing)進(jin)(jin),物(wu)(wu)料(liao)(liao)(liao)在(zai)此(ci)矩形抄(chao)(chao)(chao)板(ban)(ban)內(nei)(nei)(nei)進(jin)(jin)行(xing)充分干燥(zao),由此(ci)完成干燥(zao)目的(de)(de)(de)。
