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(tong)軸水平放置的(de)內、中、外(wai)筒(tong)套疊組成(cheng),這就使筒(tong)體的(de)截(jie)面(mian)得到充分的(de)利用。其筒(tong)體外(wai)形總長度約為(wei)與之相當的(de)單筒(tong)的(de)30-35%。從而大幅(fu)度地(di)減少占地(di)面(mian)積和廠房建筑面(mian)積。
該(gai)機的(de)支(zhi)承裝置(zhi),是在(zai)外筒上(shang)輪帶(dai)與(yu)托輪支(zhi)承,由(you)電機直接(jie)帶(dai)動(dong)托輪。通過(guo)托輪與(yu)輪帶(dai)摩擦,使筒體轉動(dong)。該(gai)機總體結構緊湊、合理、簡單,為便(bian)于磨損件的(de)檢修更換,在(zai)中間設計成軸向剖分式,用螺栓固定連接(jie)。
工作原理
物(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置(zhi)進(jin)(jin)(jin)入(ru)回轉滾(gun)筒(tong)(tong)的(de)(de)內(nei)(nei)層(ceng)(ceng)(ceng),實現(xian)順流烘(hong)干(gan)(gan)(gan),物(wu)(wu)料(liao)(liao)在(zai)(zai)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)抄板下不斷(duan)抄起、散落呈(cheng)(cheng)螺旋行(xing)進(jin)(jin)(jin)式實現(xian)熱(re)交換,物(wu)(wu)料(liao)(liao)移動至(zhi)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)另一(yi)端(duan)進(jin)(jin)(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)逆流烘(hong)干(gan)(gan)(gan),物(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不斷(duan)地(di)被反(fan)復揚進(jin)(jin)(jin),呈(cheng)(cheng)進(jin)(jin)(jin)兩步(bu)退一(yi)步(bu)的(de)(de)行(xing)進(jin)(jin)(jin)方(fang)式,物(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充分吸收(shou)內(nei)(nei)層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)散發的(de)(de)熱(re)量,又吸收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)(de)熱(re)量,同時(shi)又延長了干(gan)(gan)(gan)燥時(shi)間,物(wu)(wu)料(liao)(liao)在(zai)(zai)此達到(dao)干(gan)(gan)(gan)燥狀態。物(wu)(wu)料(liao)(liao)行(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)(ceng)另一(yi)端(duan)而(er)落入(ru)外層(ceng)(ceng)(ceng),物(wu)(wu)料(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)(nei)呈(cheng)(cheng)矩形(xing)(xing)多回路方(fang)式行(xing)進(jin)(jin)(jin),達到(dao)干(gan)(gan)(gan)燥效(xiao)果(guo)的(de)(de)物(wu)(wu)料(liao)(liao)在(zai)(zai)熱(re)風作用下快速行(xing)進(jin)(jin)(jin)排出滾(gun)筒(tong)(tong),沒有達到(dao)干(gan)(gan)(gan)燥效(xiao)果(guo)的(de)(de)濕物(wu)(wu)料(liao)(liao)因自重(zhong)而(er)不能快速行(xing)進(jin)(jin)(jin),物(wu)(wu)料(liao)(liao)在(zai)(zai)此矩形(xing)(xing)抄板內(nei)(nei)進(jin)(jin)(jin)行(xing)充分干(gan)(gan)(gan)燥,由此完成干(gan)(gan)(gan)燥目的(de)(de)。
