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(tong)(tong)體(ti)部分由三個同軸(zhou)水(shui)平放置的(de)內、中、外(wai)筒(tong)(tong)套疊組成，這(zhe)就使筒(tong)(tong)體(ti)的(de)截面(mian)得到充分的(de)利用(yong)。其筒(tong)(tong)體(ti)外(wai)形(xing)總(zong)長度約為(wei)與之相當的(de)單筒(tong)(tong)的(de)30-35%。從(cong)而大幅度地減少占(zhan)地面(mian)積(ji)和廠房建筑面(mian)積(ji)。
該機的(de)支(zhi)承(cheng)裝(zhuang)置(zhi)，是(shi)在外(wai)筒上輪(lun)帶與托輪(lun)支(zhi)承(cheng)，由電機直接帶動托輪(lun)。通(tong)過托輪(lun)與輪(lun)帶摩(mo)擦，使筒體(ti)轉動。該機總體(ti)結構緊(jin)湊、合(he)理、簡(jian)單，為便于磨(mo)損(sun)件的(de)檢修更(geng)換，在中間設計成軸向剖(pou)分式，用螺栓固(gu)定連接。
工作原理
物(wu)(wu)料(liao)(liao)由(you)(you)供(gong)料(liao)(liao)裝置(zhi)進(jin)入(ru)回轉滾筒(tong)的(de)(de)內(nei)(nei)層(ceng)(ceng)(ceng),實現順(shun)流烘干,物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)抄板下不(bu)(bu)斷(duan)(duan)抄起、散(san)落呈(cheng)螺旋行(xing)(xing)(xing)進(jin)式實現熱(re)交換，物(wu)(wu)料(liao)(liao)移(yi)動至內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)另一端進(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng)，進(jin)行(xing)(xing)(xing)逆(ni)流烘干，物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)不(bu)(bu)斷(duan)(duan)地(di)被反復(fu)揚進(jin)，呈(cheng)進(jin)兩步退一步的(de)(de)行(xing)(xing)(xing)進(jin)方式，物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)既充(chong)分(fen)吸收內(nei)(nei)層(ceng)(ceng)(ceng)滾筒(tong)散(san)發的(de)(de)熱(re)量，又吸收中(zhong)層(ceng)(ceng)(ceng)滾筒(tong)的(de)(de)熱(re)量，同時又延長了干燥(zao)時間，物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)此(ci)達到(dao)干燥(zao)狀態。物(wu)(wu)料(liao)(liao)行(xing)(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)另一端而落入(ru)外(wai)(wai)層(ceng)(ceng)(ceng)，物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)外(wai)(wai)層(ceng)(ceng)(ceng)滾筒(tong)內(nei)(nei)呈(cheng)矩形多(duo)回路方式行(xing)(xing)(xing)進(jin)，達到(dao)干燥(zao)效(xiao)果的(de)(de)物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)熱(re)風作用下快(kuai)速行(xing)(xing)(xing)進(jin)排出滾筒(tong)，沒有達到(dao)干燥(zao)效(xiao)果的(de)(de)濕物(wu)(wu)料(liao)(liao)因自重而不(bu)(bu)能快(kuai)速行(xing)(xing)(xing)進(jin)，物(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)(zai)此(ci)矩形抄板內(nei)(nei)進(jin)行(xing)(xing)(xing)充(chong)分(fen)干燥(zao)，由(you)(you)此(ci)完(wan)成干燥(zao)目(mu)的(de)(de)。
