產品概況(kuang)
回轉式三筒烘干機改進原單筒烘干機內部結構，增加入機前濕料的預烘干和延長濕料在機內烘干時間，再加上密封、保溫以及合理的配套措施，使烘干機生產能力與原單筒式烘干機相比，提高48-80%，單位容積蒸發強度可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進、運行參數合理，操作簡單可行，廣泛應用于各個行業的礦渣、粘土、煤。
產(chan)品結構
三筒(tong)(tong)(tong)(tong)(tong)式烘(hong)干機(ji)是通過對單筒(tong)(tong)(tong)(tong)(tong)烘(hong)干機(ji)的單筒(tong)(tong)(tong)(tong)(tong)體(ti)改(gai)為套疊在一起(qi)的三筒(tong)(tong)(tong)(tong)(tong)，以縮短烘(hong)干機(ji)體(ti)的外(wai)(wai)形尺寸。該(gai)機(ji)工作(zuo)時，物料和(he)熱氣流(liu)依次進入內至外(wai)(wai)筒(tong)(tong)(tong)(tong)(tong)體(ti)，在機(ji)體(ti)Z形往復折流(liu)后，充分(fen)利用熱能烘(hong)干物料后再(zai)卸出。
烘(hong)干機筒(tong)體(ti)部分(fen)(fen)由三(san)個同軸水平放置的(de)內、中、外筒(tong)套疊組成(cheng)，這就使筒(tong)體(ti)的(de)截(jie)面(mian)得到充分(fen)(fen)的(de)利用。其筒(tong)體(ti)外形總長度(du)約為與之相當的(de)單筒(tong)的(de)30-35%。從而(er)大(da)幅度(du)地減(jian)少占地面(mian)積(ji)和廠房建筑面(mian)積(ji)。
該機(ji)(ji)的支(zhi)承(cheng)裝置，是在外筒上輪(lun)(lun)帶與(yu)托輪(lun)(lun)支(zhi)承(cheng)，由(you)電(dian)機(ji)(ji)直接帶動托輪(lun)(lun)。通過托輪(lun)(lun)與(yu)輪(lun)(lun)帶摩擦，使筒體轉動。該機(ji)(ji)總體結構緊湊(cou)、合(he)理(li)、簡單，為便于磨損件的檢修(xiu)更換(huan)，在中(zhong)間設計成(cheng)軸向剖分式，用螺栓固定連接。
工作原理
物(wu)(wu)(wu)料(liao)由(you)供料(liao)裝置進(jin)(jin)入(ru)回(hui)轉滾筒的(de)內(nei)層(ceng)(ceng)(ceng),實現(xian)順流(liu)烘干,物(wu)(wu)(wu)料(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)的(de)抄板下(xia)不斷抄起(qi)、散(san)落呈(cheng)螺旋行(xing)(xing)進(jin)(jin)式實現(xian)熱交換，物(wu)(wu)(wu)料(liao)移動至內(nei)層(ceng)(ceng)(ceng)的(de)另(ling)一端進(jin)(jin)入(ru)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)(xing)逆(ni)流(liu)烘干，物(wu)(wu)(wu)料(liao)在(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)不斷地被反復(fu)揚進(jin)(jin)，呈(cheng)進(jin)(jin)兩步退(tui)一步的(de)行(xing)(xing)進(jin)(jin)方式，物(wu)(wu)(wu)料(liao)在(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)既(ji)充(chong)分吸收內(nei)層(ceng)(ceng)(ceng)滾筒散(san)發(fa)的(de)熱量，又(you)吸收中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)滾筒的(de)熱量，同(tong)時又(you)延長了干燥時間，物(wu)(wu)(wu)料(liao)在(zai)此達(da)(da)到(dao)干燥狀態(tai)。物(wu)(wu)(wu)料(liao)行(xing)(xing)至中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)另(ling)一端而落入(ru)外層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)在(zai)外層(ceng)(ceng)(ceng)滾筒內(nei)呈(cheng)矩形多回(hui)路方式行(xing)(xing)進(jin)(jin)，達(da)(da)到(dao)干燥效果的(de)物(wu)(wu)(wu)料(liao)在(zai)熱風作用下(xia)快(kuai)速(su)行(xing)(xing)進(jin)(jin)排出滾筒，沒有達(da)(da)到(dao)干燥效果的(de)濕物(wu)(wu)(wu)料(liao)因自重(zhong)而不能快(kuai)速(su)行(xing)(xing)進(jin)(jin)，物(wu)(wu)(wu)料(liao)在(zai)此矩形抄板內(nei)進(jin)(jin)行(xing)(xing)充(chong)分干燥，由(you)此完(wan)成(cheng)干燥目的(de)。
