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)(tong)體部分由三個同軸(zhou)水(shui)平(ping)放(fang)置的(de)內、中、外筒(tong)(tong)(tong)套(tao)疊組成(cheng),這就使筒(tong)(tong)(tong)體的(de)截面(mian)(mian)得到充分的(de)利(li)用(yong)。其筒(tong)(tong)(tong)體外形總長度約為與之相當的(de)單筒(tong)(tong)(tong)的(de)30-35%。從而大幅度地減少占地面(mian)(mian)積和廠房(fang)建筑(zhu)面(mian)(mian)積。
該機的(de)支承裝置,是在外筒上輪(lun)(lun)帶與托輪(lun)(lun)支承,由電機直接(jie)(jie)帶動(dong)托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶摩擦,使(shi)筒體(ti)轉(zhuan)動(dong)。該機總體(ti)結構(gou)緊湊、合理(li)、簡單,為便于磨損件的(de)檢修更換(huan),在中間設計成軸向剖分式,用螺(luo)栓固(gu)定連接(jie)(jie)。
工作原理
物(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置進(jin)(jin)入回轉(zhuan)滾筒的(de)(de)(de)內層(ceng)(ceng)(ceng)(ceng),實現(xian)順流烘(hong)干(gan),物(wu)料(liao)(liao)(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)板下不(bu)斷(duan)抄(chao)起、散落呈(cheng)螺旋(xuan)行進(jin)(jin)式實現(xian)熱交換(huan),物(wu)料(liao)(liao)(liao)移動至內層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另(ling)一(yi)(yi)端進(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)行逆流烘(hong)干(gan),物(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷(duan)地被反復揚進(jin)(jin),呈(cheng)進(jin)(jin)兩(liang)步退一(yi)(yi)步的(de)(de)(de)行進(jin)(jin)方(fang)式,物(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)既(ji)充分吸收(shou)(shou)內層(ceng)(ceng)(ceng)(ceng)滾筒散發(fa)的(de)(de)(de)熱量,又(you)吸收(shou)(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)滾筒的(de)(de)(de)熱量,同(tong)時(shi)又(you)延長了干(gan)燥(zao)(zao)時(shi)間,物(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)達到干(gan)燥(zao)(zao)狀態。物(wu)料(liao)(liao)(liao)行至中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一(yi)(yi)端而(er)落入外層(ceng)(ceng)(ceng)(ceng),物(wu)料(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾筒內呈(cheng)矩(ju)形多回路方(fang)式行進(jin)(jin),達到干(gan)燥(zao)(zao)效(xiao)(xiao)果的(de)(de)(de)物(wu)料(liao)(liao)(liao)在(zai)(zai)熱風作用下快(kuai)速行進(jin)(jin)排出滾筒,沒有(you)達到干(gan)燥(zao)(zao)效(xiao)(xiao)果的(de)(de)(de)濕(shi)物(wu)料(liao)(liao)(liao)因自重(zhong)而(er)不(bu)能快(kuai)速行進(jin)(jin),物(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)矩(ju)形抄(chao)板內進(jin)(jin)行充分干(gan)燥(zao)(zao),由此(ci)完成干(gan)燥(zao)(zao)目的(de)(de)(de)。
