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(ji)筒(tong)體部分由三個同軸水平放置的內、中、外筒(tong)套疊組成,這就使筒(tong)體的截(jie)面得到充分的利用。其(qi)筒(tong)體外形總長度約為與之相(xiang)當的單筒(tong)的30-35%。從而大幅(fu)度地減少占(zhan)地面積(ji)和廠房(fang)建筑(zhu)面積(ji)。
該(gai)機的支(zhi)承(cheng)裝置,是在(zai)外筒上輪帶與(yu)(yu)托(tuo)輪支(zhi)承(cheng),由電(dian)機直接帶動托(tuo)輪。通(tong)過托(tuo)輪與(yu)(yu)輪帶摩(mo)擦,使(shi)筒體(ti)轉動。該(gai)機總(zong)體(ti)結構緊湊、合理、簡單(dan),為(wei)便于磨損件的檢(jian)修(xiu)更換(huan),在(zai)中間設計成(cheng)軸(zhou)向剖分(fen)式(shi),用螺(luo)栓(shuan)固定連接。
工(gong)作原理
物(wu)(wu)料(liao)由(you)供料(liao)裝置進(jin)(jin)(jin)(jin)入回(hui)轉滾(gun)筒(tong)(tong)的(de)(de)(de)內(nei)層(ceng)(ceng)(ceng),實現順流烘(hong)干(gan)(gan),物(wu)(wu)料(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)板(ban)下不斷抄(chao)起、散落(luo)呈螺旋行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)式實現熱交換,物(wu)(wu)料(liao)移動至內(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)另一端(duan)(duan)進(jin)(jin)(jin)(jin)入中層(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)行(xing)(xing)(xing)逆(ni)流烘(hong)干(gan)(gan),物(wu)(wu)料(liao)在(zai)中層(ceng)(ceng)(ceng)不斷地被反復(fu)揚進(jin)(jin)(jin)(jin),呈進(jin)(jin)(jin)(jin)兩(liang)步退一步的(de)(de)(de)行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)方式,物(wu)(wu)料(liao)在(zai)中層(ceng)(ceng)(ceng)既(ji)充(chong)分吸(xi)收內(nei)層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)散發的(de)(de)(de)熱量(liang),又吸(xi)收中層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)(de)(de)熱量(liang),同時(shi)又延長了(le)干(gan)(gan)燥時(shi)間,物(wu)(wu)料(liao)在(zai)此達到干(gan)(gan)燥狀態(tai)。物(wu)(wu)料(liao)行(xing)(xing)(xing)至中層(ceng)(ceng)(ceng)另一端(duan)(duan)而落(luo)入外(wai)(wai)層(ceng)(ceng)(ceng),物(wu)(wu)料(liao)在(zai)外(wai)(wai)層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)呈矩形多回(hui)路方式行(xing)(xing)(xing)進(jin)(jin)(jin)(jin),達到干(gan)(gan)燥效果的(de)(de)(de)物(wu)(wu)料(liao)在(zai)熱風作用下快(kuai)速行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)排出(chu)滾(gun)筒(tong)(tong),沒有達到干(gan)(gan)燥效果的(de)(de)(de)濕物(wu)(wu)料(liao)因自重而不能快(kuai)速行(xing)(xing)(xing)進(jin)(jin)(jin)(jin),物(wu)(wu)料(liao)在(zai)此矩形抄(chao)板(ban)內(nei)進(jin)(jin)(jin)(jin)行(xing)(xing)(xing)充(chong)分干(gan)(gan)燥,由(you)此完成干(gan)(gan)燥目的(de)(de)(de)。
