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。
烘干機筒體部(bu)分由三個同軸(zhou)水(shui)平放置的內、中、外筒套疊(die)組成(cheng),這就使(shi)筒體的截面得到充分的利用。其筒體外形總長度(du)約(yue)為與之(zhi)相當的單筒的30-35%。從而(er)大幅度(du)地減少占地面積和(he)廠房建筑(zhu)面積。
該(gai)機的支承(cheng)裝置,是在(zai)外筒上(shang)輪(lun)帶與托(tuo)輪(lun)支承(cheng),由電機直(zhi)接(jie)帶動(dong)托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶摩擦(ca),使(shi)筒體轉動(dong)。該(gai)機總體結(jie)構(gou)緊湊(cou)、合理、簡(jian)單,為便于磨損件的檢修更換,在(zai)中間(jian)設計(ji)成(cheng)軸(zhou)向剖分式,用螺栓固定連接(jie)。
工作原理
物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)由(you)供料(liao)(liao)裝置進(jin)入(ru)回(hui)轉滾筒(tong)的(de)(de)內(nei)(nei)層(ceng)(ceng),實現(xian)順流烘干(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)(nei)層(ceng)(ceng)的(de)(de)抄板下不斷(duan)抄起、散落呈螺旋(xuan)行(xing)(xing)(xing)進(jin)式(shi)(shi)實現(xian)熱交換,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)移(yi)動至內(nei)(nei)層(ceng)(ceng)的(de)(de)另(ling)一(yi)(yi)端進(jin)入(ru)中(zhong)層(ceng)(ceng),進(jin)行(xing)(xing)(xing)逆(ni)流烘干(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)不斷(duan)地被反復揚進(jin),呈進(jin)兩步退一(yi)(yi)步的(de)(de)行(xing)(xing)(xing)進(jin)方式(shi)(shi),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)既充(chong)分(fen)吸(xi)收(shou)(shou)內(nei)(nei)層(ceng)(ceng)滾筒(tong)散發(fa)的(de)(de)熱量(liang),又吸(xi)收(shou)(shou)中(zhong)層(ceng)(ceng)滾筒(tong)的(de)(de)熱量(liang),同時(shi)又延長了干(gan)(gan)燥(zao)(zao)時(shi)間,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此達到干(gan)(gan)燥(zao)(zao)狀(zhuang)態。物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)(xing)至中(zhong)層(ceng)(ceng)另(ling)一(yi)(yi)端而落入(ru)外(wai)層(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)外(wai)層(ceng)(ceng)滾筒(tong)內(nei)(nei)呈矩(ju)形(xing)多回(hui)路方式(shi)(shi)行(xing)(xing)(xing)進(jin),達到干(gan)(gan)燥(zao)(zao)效果的(de)(de)物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)熱風作用下快速行(xing)(xing)(xing)進(jin)排出滾筒(tong),沒(mei)有達到干(gan)(gan)燥(zao)(zao)效果的(de)(de)濕物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)因自重而不能快速行(xing)(xing)(xing)進(jin),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此矩(ju)形(xing)抄板內(nei)(nei)進(jin)行(xing)(xing)(xing)充(chong)分(fen)干(gan)(gan)燥(zao)(zao),由(you)此完成(cheng)干(gan)(gan)燥(zao)(zao)目的(de)(de)。
