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(gan)機(ji)筒體(ti)部分由三個同(tong)軸水平(ping)放置的(de)(de)內、中、外(wai)筒套(tao)疊組成,這就使筒體(ti)的(de)(de)截面得到充分的(de)(de)利用。其筒體(ti)外(wai)形總長(chang)度(du)(du)約為與之相當的(de)(de)單筒的(de)(de)30-35%。從而(er)大幅度(du)(du)地(di)減(jian)少占地(di)面積(ji)和(he)廠房建筑面積(ji)。
該機的(de)(de)支承裝置(zhi),是在外筒(tong)上(shang)輪(lun)(lun)帶(dai)與托(tuo)(tuo)(tuo)輪(lun)(lun)支承,由電(dian)機直接帶(dai)動(dong)托(tuo)(tuo)(tuo)輪(lun)(lun)。通(tong)過(guo)托(tuo)(tuo)(tuo)輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使(shi)筒(tong)體轉動(dong)。該機總體結(jie)構緊湊、合(he)理、簡單(dan),為便于磨損件(jian)的(de)(de)檢修更(geng)換,在中(zhong)間設(she)計成軸向剖分(fen)式(shi),用螺(luo)栓固定連接。
工作(zuo)原理
物(wu)(wu)(wu)(wu)料(liao)由供料(liao)裝置進(jin)(jin)(jin)入回轉(zhuan)滾(gun)筒(tong)的內(nei)層(ceng)(ceng),實(shi)現(xian)(xian)順流(liu)(liu)烘(hong)干(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)內(nei)層(ceng)(ceng)的抄(chao)板下不斷抄(chao)起、散落呈螺旋行(xing)(xing)進(jin)(jin)(jin)式(shi)實(shi)現(xian)(xian)熱交換,物(wu)(wu)(wu)(wu)料(liao)移動至(zhi)內(nei)層(ceng)(ceng)的另一(yi)(yi)端(duan)進(jin)(jin)(jin)入中(zhong)(zhong)(zhong)層(ceng)(ceng),進(jin)(jin)(jin)行(xing)(xing)逆流(liu)(liu)烘(hong)干(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)不斷地(di)被(bei)反復(fu)揚(yang)進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩(liang)步(bu)退(tui)一(yi)(yi)步(bu)的行(xing)(xing)進(jin)(jin)(jin)方式(shi),物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)既充分(fen)吸(xi)(xi)收內(nei)層(ceng)(ceng)滾(gun)筒(tong)散發的熱量(liang),又吸(xi)(xi)收中(zhong)(zhong)(zhong)層(ceng)(ceng)滾(gun)筒(tong)的熱量(liang),同時(shi)又延長了干(gan)(gan)燥(zao)時(shi)間(jian),物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)此達到(dao)干(gan)(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)行(xing)(xing)至(zhi)中(zhong)(zhong)(zhong)層(ceng)(ceng)另一(yi)(yi)端(duan)而落入外層(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)外層(ceng)(ceng)滾(gun)筒(tong)內(nei)呈矩形(xing)多回路方式(shi)行(xing)(xing)進(jin)(jin)(jin),達到(dao)干(gan)(gan)燥(zao)效果的物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)熱風作用下快速(su)行(xing)(xing)進(jin)(jin)(jin)排出滾(gun)筒(tong),沒(mei)有達到(dao)干(gan)(gan)燥(zao)效果的濕(shi)物(wu)(wu)(wu)(wu)料(liao)因(yin)自重而不能快速(su)行(xing)(xing)進(jin)(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)此矩形(xing)抄(chao)板內(nei)進(jin)(jin)(jin)行(xing)(xing)充分(fen)干(gan)(gan)燥(zao),由此完成干(gan)(gan)燥(zao)目的。
