產品結構
三筒式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)三個同軸水平放置的(de)(de)內、中、外(wai)筒(tong)(tong)套疊(die)組成,這就使筒(tong)(tong)體的(de)(de)截面得(de)到充分的(de)(de)利(li)用。其(qi)筒(tong)(tong)體外(wai)形總長度約(yue)為與之相當的(de)(de)單筒(tong)(tong)的(de)(de)30-35%。從而(er)大幅(fu)度地減少占(zhan)地面積和(he)廠房建筑(zhu)面積。
該機的(de)支承(cheng)裝(zhuang)置(zhi),是(shi)在(zai)外筒上(shang)輪(lun)帶與(yu)托(tuo)輪(lun)支承(cheng),由電機直(zhi)接帶動托(tuo)輪(lun)。通過托(tuo)輪(lun)與(yu)輪(lun)帶摩擦,使筒體轉動。該機總體結構緊湊、合理(li)、簡單,為(wei)便于磨損(sun)件的(de)檢修更換,在(zai)中間設(she)計(ji)成軸(zhou)向剖(pou)分式,用螺栓(shuan)固定連接。
工作原理
物(wu)(wu)料(liao)由供料(liao)裝(zhuang)置進(jin)(jin)入(ru)回(hui)(hui)轉滾(gun)筒(tong)的(de)內層(ceng)(ceng)(ceng),實現(xian)順(shun)流(liu)烘干(gan),物(wu)(wu)料(liao)在(zai)內層(ceng)(ceng)(ceng)的(de)抄板(ban)下(xia)不(bu)斷(duan)(duan)抄起、散落(luo)呈(cheng)(cheng)螺旋(xuan)行(xing)(xing)進(jin)(jin)式(shi)實現(xian)熱(re)(re)交換,物(wu)(wu)料(liao)移動至內層(ceng)(ceng)(ceng)的(de)另(ling)一端進(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)行(xing)(xing)逆流(liu)烘干(gan),物(wu)(wu)料(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)不(bu)斷(duan)(duan)地(di)被反(fan)復揚進(jin)(jin),呈(cheng)(cheng)進(jin)(jin)兩(liang)步退(tui)一步的(de)行(xing)(xing)進(jin)(jin)方式(shi),物(wu)(wu)料(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)既(ji)充(chong)(chong)分(fen)吸收(shou)內層(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的(de)熱(re)(re)量(liang),又吸收(shou)中(zhong)層(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)熱(re)(re)量(liang),同(tong)時又延(yan)長了干(gan)燥(zao)(zao)時間,物(wu)(wu)料(liao)在(zai)此達(da)到干(gan)燥(zao)(zao)狀態。物(wu)(wu)料(liao)行(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)另(ling)一端而落(luo)入(ru)外(wai)層(ceng)(ceng)(ceng),物(wu)(wu)料(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)滾(gun)筒(tong)內呈(cheng)(cheng)矩(ju)形多回(hui)(hui)路方式(shi)行(xing)(xing)進(jin)(jin),達(da)到干(gan)燥(zao)(zao)效(xiao)果(guo)的(de)物(wu)(wu)料(liao)在(zai)熱(re)(re)風作用下(xia)快(kuai)速行(xing)(xing)進(jin)(jin)排(pai)出滾(gun)筒(tong),沒有達(da)到干(gan)燥(zao)(zao)效(xiao)果(guo)的(de)濕物(wu)(wu)料(liao)因(yin)自重(zhong)而不(bu)能快(kuai)速行(xing)(xing)進(jin)(jin),物(wu)(wu)料(liao)在(zai)此矩(ju)形抄板(ban)內進(jin)(jin)行(xing)(xing)充(chong)(chong)分(fen)干(gan)燥(zao)(zao),由此完成干(gan)燥(zao)(zao)目的(de)。
