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(ti)部(bu)分(fen)由三個同軸水平放置的(de)內(nei)、中、外筒(tong)(tong)套疊組成,這就使(shi)筒(tong)(tong)體(ti)的(de)截面得到(dao)充分(fen)的(de)利(li)用。其筒(tong)(tong)體(ti)外形(xing)總長度約為與之相當的(de)單(dan)筒(tong)(tong)的(de)30-35%。從(cong)而大幅(fu)度地減(jian)少占(zhan)地面積和廠房(fang)建筑面積。
該(gai)機的支承裝(zhuang)置,是在(zai)外(wai)筒上(shang)輪(lun)帶與托輪(lun)支承,由(you)電機直(zhi)接(jie)帶動(dong)托輪(lun)。通過托輪(lun)與輪(lun)帶摩(mo)擦,使筒體轉(zhuan)動(dong)。該(gai)機總體結構緊湊、合理、簡單,為便于磨損件(jian)的檢修(xiu)更換,在(zai)中間設(she)計成軸向(xiang)剖分式(shi),用螺栓固(gu)定連接(jie)。
工作原理(li)
物(wu)(wu)(wu)(wu)(wu)料(liao)由供料(liao)裝置進(jin)(jin)(jin)(jin)入(ru)回轉滾(gun)(gun)筒的內(nei)(nei)(nei)層(ceng)(ceng),實現順(shun)流烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)內(nei)(nei)(nei)層(ceng)(ceng)的抄板下不斷抄起、散落(luo)呈螺旋行進(jin)(jin)(jin)(jin)式實現熱(re)(re)交換,物(wu)(wu)(wu)(wu)(wu)料(liao)移動至內(nei)(nei)(nei)層(ceng)(ceng)的另一端進(jin)(jin)(jin)(jin)入(ru)中(zhong)層(ceng)(ceng),進(jin)(jin)(jin)(jin)行逆流烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)中(zhong)層(ceng)(ceng)不斷地(di)被反復揚進(jin)(jin)(jin)(jin),呈進(jin)(jin)(jin)(jin)兩步退一步的行進(jin)(jin)(jin)(jin)方式,物(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)中(zhong)層(ceng)(ceng)既(ji)充分(fen)吸收(shou)內(nei)(nei)(nei)層(ceng)(ceng)滾(gun)(gun)筒散發(fa)的熱(re)(re)量(liang),又吸收(shou)中(zhong)層(ceng)(ceng)滾(gun)(gun)筒的熱(re)(re)量(liang),同時(shi)又延長(chang)了(le)干(gan)(gan)(gan)燥(zao)(zao)時(shi)間,物(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)此達到(dao)干(gan)(gan)(gan)燥(zao)(zao)狀態(tai)。物(wu)(wu)(wu)(wu)(wu)料(liao)行至中(zhong)層(ceng)(ceng)另一端而(er)落(luo)入(ru)外層(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)外層(ceng)(ceng)滾(gun)(gun)筒內(nei)(nei)(nei)呈矩形(xing)多(duo)回路方式行進(jin)(jin)(jin)(jin),達到(dao)干(gan)(gan)(gan)燥(zao)(zao)效果的物(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)熱(re)(re)風作用下快速(su)行進(jin)(jin)(jin)(jin)排(pai)出(chu)滾(gun)(gun)筒,沒有達到(dao)干(gan)(gan)(gan)燥(zao)(zao)效果的濕物(wu)(wu)(wu)(wu)(wu)料(liao)因自(zi)重而(er)不能快速(su)行進(jin)(jin)(jin)(jin),物(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)此矩形(xing)抄板內(nei)(nei)(nei)進(jin)(jin)(jin)(jin)行充分(fen)干(gan)(gan)(gan)燥(zao)(zao),由此完(wan)成干(gan)(gan)(gan)燥(zao)(zao)目的。
