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。
烘干機筒體(ti)部分由三個(ge)同軸水平放置的(de)內、中、外(wai)筒套疊組成,這就(jiu)使筒體(ti)的(de)截面(mian)得到充分的(de)利用。其筒體(ti)外(wai)形總(zong)長度(du)約為與(yu)之相當的(de)單筒的(de)30-35%。從(cong)而大幅(fu)度(du)地(di)減少占地(di)面(mian)積和(he)廠房建筑面(mian)積。
該(gai)機的(de)支承裝置,是在外(wai)筒上輪(lun)(lun)帶與(yu)托輪(lun)(lun)支承,由電機直(zhi)接帶動(dong)托輪(lun)(lun)。通過托輪(lun)(lun)與(yu)輪(lun)(lun)帶摩擦,使(shi)筒體轉動(dong)。該(gai)機總體結構緊湊(cou)、合(he)理、簡單,為(wei)便于磨損件(jian)的(de)檢修更(geng)換,在中間設計(ji)成(cheng)軸(zhou)向剖分(fen)式,用螺(luo)栓固定連接。
工作原理(li)
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置進(jin)(jin)(jin)入回(hui)轉(zhuan)滾(gun)筒的內(nei)層(ceng)(ceng),實現順(shun)流烘干(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)的抄(chao)板(ban)下(xia)不斷抄(chao)起、散落(luo)呈(cheng)螺旋(xuan)行(xing)(xing)進(jin)(jin)(jin)式實現熱(re)(re)交(jiao)換,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)的另一(yi)端(duan)進(jin)(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng),進(jin)(jin)(jin)行(xing)(xing)逆流烘干(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)不斷地被反復揚(yang)進(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)兩步退(tui)一(yi)步的行(xing)(xing)進(jin)(jin)(jin)方式,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)既充分(fen)吸收內(nei)層(ceng)(ceng)滾(gun)筒散發的熱(re)(re)量(liang)(liang),又(you)吸收中(zhong)(zhong)層(ceng)(ceng)滾(gun)筒的熱(re)(re)量(liang)(liang),同時(shi)又(you)延長了干(gan)(gan)燥(zao)時(shi)間(jian),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此達到(dao)干(gan)(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)另一(yi)端(duan)而(er)落(luo)入外(wai)層(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)滾(gun)筒內(nei)呈(cheng)矩形多(duo)回(hui)路方式行(xing)(xing)進(jin)(jin)(jin),達到(dao)干(gan)(gan)燥(zao)效果的物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)熱(re)(re)風作用下(xia)快速行(xing)(xing)進(jin)(jin)(jin)排出滾(gun)筒,沒(mei)有達到(dao)干(gan)(gan)燥(zao)效果的濕物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)因自重而(er)不能(neng)快速行(xing)(xing)進(jin)(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此矩形抄(chao)板(ban)內(nei)進(jin)(jin)(jin)行(xing)(xing)充分(fen)干(gan)(gan)燥(zao),由此完成干(gan)(gan)燥(zao)目(mu)的。
