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(hong)干機筒(tong)體(ti)部分(fen)由三個同軸水(shui)平放置的(de)(de)內、中、外筒(tong)套疊組成,這就使筒(tong)體(ti)的(de)(de)截面(mian)(mian)得到充(chong)分(fen)的(de)(de)利用。其(qi)筒(tong)體(ti)外形總(zong)長度約為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度地(di)減少占地(di)面(mian)(mian)積和廠(chang)房(fang)建筑面(mian)(mian)積。
該機(ji)(ji)的(de)支(zhi)承裝(zhuang)置,是在(zai)外(wai)筒(tong)上輪(lun)帶與(yu)托(tuo)輪(lun)支(zhi)承,由電機(ji)(ji)直接(jie)帶動(dong)托(tuo)輪(lun)。通(tong)過托(tuo)輪(lun)與(yu)輪(lun)帶摩擦,使(shi)筒(tong)體轉動(dong)。該機(ji)(ji)總體結構(gou)緊(jin)湊、合(he)理、簡單,為便于磨損(sun)件的(de)檢(jian)修更換,在(zai)中(zhong)間設計成軸向(xiang)剖(pou)分式(shi),用螺栓固定(ding)連接(jie)。
工作(zuo)原理
物(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)入(ru)(ru)回(hui)轉滾筒(tong)的(de)內(nei)層(ceng)(ceng),實(shi)現順流烘干(gan),物(wu)料(liao)(liao)在(zai)(zai)(zai)內(nei)層(ceng)(ceng)的(de)抄板(ban)(ban)下(xia)不(bu)斷(duan)(duan)抄起、散落(luo)呈(cheng)螺旋行(xing)(xing)(xing)進(jin)(jin)式實(shi)現熱交換(huan),物(wu)料(liao)(liao)移(yi)動至(zhi)內(nei)層(ceng)(ceng)的(de)另一端進(jin)(jin)入(ru)(ru)中層(ceng)(ceng),進(jin)(jin)行(xing)(xing)(xing)逆流烘干(gan),物(wu)料(liao)(liao)在(zai)(zai)(zai)中層(ceng)(ceng)不(bu)斷(duan)(duan)地(di)被反復揚進(jin)(jin),呈(cheng)進(jin)(jin)兩步(bu)退一步(bu)的(de)行(xing)(xing)(xing)進(jin)(jin)方式,物(wu)料(liao)(liao)在(zai)(zai)(zai)中層(ceng)(ceng)既充分(fen)吸收內(nei)層(ceng)(ceng)滾筒(tong)散發的(de)熱量(liang),又吸收中層(ceng)(ceng)滾筒(tong)的(de)熱量(liang),同時又延(yan)長了干(gan)燥(zao)(zao)時間,物(wu)料(liao)(liao)在(zai)(zai)(zai)此達到干(gan)燥(zao)(zao)狀態。物(wu)料(liao)(liao)行(xing)(xing)(xing)至(zhi)中層(ceng)(ceng)另一端而落(luo)入(ru)(ru)外(wai)層(ceng)(ceng),物(wu)料(liao)(liao)在(zai)(zai)(zai)外(wai)層(ceng)(ceng)滾筒(tong)內(nei)呈(cheng)矩(ju)形多回(hui)路方式行(xing)(xing)(xing)進(jin)(jin),達到干(gan)燥(zao)(zao)效果(guo)的(de)物(wu)料(liao)(liao)在(zai)(zai)(zai)熱風(feng)作用下(xia)快速行(xing)(xing)(xing)進(jin)(jin)排出滾筒(tong),沒有(you)達到干(gan)燥(zao)(zao)效果(guo)的(de)濕物(wu)料(liao)(liao)因自重(zhong)而不(bu)能(neng)快速行(xing)(xing)(xing)進(jin)(jin),物(wu)料(liao)(liao)在(zai)(zai)(zai)此矩(ju)形抄板(ban)(ban)內(nei)進(jin)(jin)行(xing)(xing)(xing)充分(fen)干(gan)燥(zao)(zao),由此完(wan)成干(gan)燥(zao)(zao)目的(de)。
