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。
烘干機筒體部分由(you)三個同軸水平放置(zhi)的內、中(zhong)、外筒套疊組成,這就使筒體的截面得到充(chong)分的利用。其(qi)筒體外形(xing)總長度約(yue)為與之相(xiang)當的單筒的30-35%。從而大幅度地減少占(zhan)地面積和廠房(fang)建(jian)筑(zhu)面積。
該機的支(zhi)承裝置,是在外(wai)筒(tong)上輪(lun)帶(dai)(dai)與托輪(lun)支(zhi)承,由電機直接(jie)帶(dai)(dai)動(dong)托輪(lun)。通過托輪(lun)與輪(lun)帶(dai)(dai)摩擦,使筒(tong)體(ti)轉(zhuan)動(dong)。該機總體(ti)結構緊湊、合理(li)、簡單,為便于磨損(sun)件的檢(jian)修更換,在中間設計成軸(zhou)向剖分式,用(yong)螺栓固定連(lian)接(jie)。
工作(zuo)原理
物(wu)(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝置進(jin)入回轉滾(gun)(gun)筒(tong)(tong)的(de)內(nei)層(ceng)(ceng)(ceng),實現(xian)(xian)順流烘(hong)干(gan),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)的(de)抄板下不(bu)斷(duan)抄起(qi)、散(san)落呈螺旋行進(jin)式(shi)實現(xian)(xian)熱(re)交(jiao)換,物(wu)(wu)料(liao)(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)的(de)另一(yi)端進(jin)入中(zhong)層(ceng)(ceng)(ceng),進(jin)行逆(ni)流烘(hong)干(gan),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)不(bu)斷(duan)地(di)被(bei)反復揚進(jin),呈進(jin)兩步退一(yi)步的(de)行進(jin)方式(shi),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)既充分(fen)吸收內(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)散(san)發(fa)的(de)熱(re)量,又吸收中(zhong)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)的(de)熱(re)量,同時又延長了干(gan)燥(zao)(zao)(zao)時間,物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)達到干(gan)燥(zao)(zao)(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)(liao)行至中(zhong)層(ceng)(ceng)(ceng)另一(yi)端而落入外層(ceng)(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)內(nei)呈矩(ju)形(xing)多(duo)回路方式(shi)行進(jin),達到干(gan)燥(zao)(zao)(zao)效(xiao)果的(de)物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)熱(re)風作用下快速行進(jin)排(pai)出滾(gun)(gun)筒(tong)(tong),沒(mei)有達到干(gan)燥(zao)(zao)(zao)效(xiao)果的(de)濕物(wu)(wu)料(liao)(liao)(liao)(liao)因自(zi)重而不(bu)能快速行進(jin),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)矩(ju)形(xing)抄板內(nei)進(jin)行充分(fen)干(gan)燥(zao)(zao)(zao),由此(ci)完成干(gan)燥(zao)(zao)(zao)目的(de)。
