產品結(jie)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(hong)干機(ji)筒(tong)體部分(fen)由三個同軸水平(ping)放置的(de)內、中、外(wai)筒(tong)套(tao)疊組成,這就使筒(tong)體的(de)截面(mian)得到充(chong)分(fen)的(de)利(li)用。其筒(tong)體外(wai)形總長(chang)度(du)約為與(yu)之(zhi)相當的(de)單筒(tong)的(de)30-35%。從(cong)而(er)大幅度(du)地減(jian)少占地面(mian)積和(he)廠房建筑面(mian)積。
該(gai)機(ji)的(de)支(zhi)承(cheng)裝置,是(shi)在外(wai)筒上(shang)輪(lun)帶(dai)與(yu)托輪(lun)支(zhi)承(cheng),由電(dian)機(ji)直接帶(dai)動托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶(dai)摩擦,使(shi)筒體(ti)轉動。該(gai)機(ji)總體(ti)結構緊(jin)湊、合理(li)、簡單,為(wei)便于磨損件的(de)檢(jian)修更換(huan),在中間(jian)設計成軸向剖分(fen)式,用(yong)螺栓固(gu)定連接。
工作原理
物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置(zhi)進(jin)(jin)(jin)入回(hui)(hui)轉滾(gun)筒(tong)(tong)的內(nei)層(ceng)(ceng),實現順(shun)流烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)層(ceng)(ceng)的抄板(ban)下(xia)(xia)不(bu)(bu)斷(duan)(duan)抄起、散(san)落呈螺旋行進(jin)(jin)(jin)式(shi)實現熱(re)交換,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)移動至內(nei)層(ceng)(ceng)的另(ling)一端進(jin)(jin)(jin)入中(zhong)層(ceng)(ceng),進(jin)(jin)(jin)行逆(ni)流烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)不(bu)(bu)斷(duan)(duan)地(di)被反復揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩(liang)步退一步的行進(jin)(jin)(jin)方(fang)式(shi),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)既充(chong)分吸(xi)收內(nei)層(ceng)(ceng)滾(gun)筒(tong)(tong)散(san)發的熱(re)量,又吸(xi)收中(zhong)層(ceng)(ceng)滾(gun)筒(tong)(tong)的熱(re)量,同(tong)時又延長了干(gan)(gan)(gan)燥(zao)時間(jian),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)達(da)到(dao)干(gan)(gan)(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)行至中(zhong)層(ceng)(ceng)另(ling)一端而落入外層(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)外層(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)呈矩形多回(hui)(hui)路方(fang)式(shi)行進(jin)(jin)(jin),達(da)到(dao)干(gan)(gan)(gan)燥(zao)效果(guo)的物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)熱(re)風作用(yong)下(xia)(xia)快速(su)行進(jin)(jin)(jin)排出滾(gun)筒(tong)(tong),沒有(you)達(da)到(dao)干(gan)(gan)(gan)燥(zao)效果(guo)的濕物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)因自(zi)重而不(bu)(bu)能快速(su)行進(jin)(jin)(jin),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)矩形抄板(ban)內(nei)進(jin)(jin)(jin)行充(chong)分干(gan)(gan)(gan)燥(zao),由此(ci)完成干(gan)(gan)(gan)燥(zao)目(mu)的。
