產(chan)品(pin)概況
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。
產品(pin)結構
三(san)筒(tong)(tong)式(shi)烘(hong)干機是通(tong)過對(dui)單筒(tong)(tong)烘(hong)干機的單筒(tong)(tong)體(ti)改(gai)為套(tao)疊在一起的三(san)筒(tong)(tong),以縮短(duan)烘(hong)干機體(ti)的外形尺寸。該機工作(zuo)時(shi),物(wu)料和熱氣流依次(ci)進入內至(zhi)外筒(tong)(tong)體(ti),在機體(ti)Z形往復折流后(hou),充分利用(yong)熱能(neng)烘(hong)干物(wu)料后(hou)再(zai)卸出。
烘干機筒體(ti)(ti)部(bu)分(fen)由(you)三個同軸水平(ping)放置的內、中、外筒套(tao)疊組成,這就(jiu)使(shi)筒體(ti)(ti)的截面得到充分(fen)的利用(yong)。其(qi)筒體(ti)(ti)外形總(zong)長度約為與(yu)之(zhi)相當的單筒的30-35%。從而大(da)幅度地減少占地面積和廠房建筑面積。
該(gai)機的支(zhi)承裝置,是在外(wai)筒(tong)上輪帶(dai)與托輪支(zhi)承,由電(dian)機直接(jie)帶(dai)動托輪。通過托輪與輪帶(dai)摩擦,使筒(tong)體(ti)轉(zhuan)動。該(gai)機總體(ti)結構緊湊、合理、簡單,為便于磨損件(jian)的檢(jian)修更換,在中間設計成軸向(xiang)剖(pou)分式(shi),用螺栓固定連接(jie)。
工作原理
物(wu)(wu)(wu)(wu)料(liao)由供(gong)料(liao)裝置進(jin)入(ru)(ru)(ru)回轉滾(gun)(gun)筒的(de)(de)內層(ceng),實現順流(liu)(liu)烘干(gan),物(wu)(wu)(wu)(wu)料(liao)在(zai)內層(ceng)的(de)(de)抄板(ban)下不(bu)斷抄起、散落(luo)呈螺旋行(xing)(xing)(xing)進(jin)式實現熱(re)(re)交換,物(wu)(wu)(wu)(wu)料(liao)移動至內層(ceng)的(de)(de)另(ling)一端(duan)進(jin)入(ru)(ru)(ru)中(zhong)(zhong)層(ceng),進(jin)行(xing)(xing)(xing)逆流(liu)(liu)烘干(gan),物(wu)(wu)(wu)(wu)料(liao)在(zai)中(zhong)(zhong)層(ceng)不(bu)斷地被反復揚進(jin),呈進(jin)兩(liang)步退(tui)一步的(de)(de)行(xing)(xing)(xing)進(jin)方式,物(wu)(wu)(wu)(wu)料(liao)在(zai)中(zhong)(zhong)層(ceng)既(ji)充分吸(xi)收內層(ceng)滾(gun)(gun)筒散發(fa)的(de)(de)熱(re)(re)量,又(you)吸(xi)收中(zhong)(zhong)層(ceng)滾(gun)(gun)筒的(de)(de)熱(re)(re)量,同(tong)時又(you)延長了干(gan)燥時間,物(wu)(wu)(wu)(wu)料(liao)在(zai)此(ci)達(da)到干(gan)燥狀態。物(wu)(wu)(wu)(wu)料(liao)行(xing)(xing)(xing)至中(zhong)(zhong)層(ceng)另(ling)一端(duan)而(er)落(luo)入(ru)(ru)(ru)外層(ceng),物(wu)(wu)(wu)(wu)料(liao)在(zai)外層(ceng)滾(gun)(gun)筒內呈矩(ju)形多回路方式行(xing)(xing)(xing)進(jin),達(da)到干(gan)燥效果的(de)(de)物(wu)(wu)(wu)(wu)料(liao)在(zai)熱(re)(re)風作用下快速(su)行(xing)(xing)(xing)進(jin)排出滾(gun)(gun)筒,沒有達(da)到干(gan)燥效果的(de)(de)濕(shi)物(wu)(wu)(wu)(wu)料(liao)因自重而(er)不(bu)能快速(su)行(xing)(xing)(xing)進(jin),物(wu)(wu)(wu)(wu)料(liao)在(zai)此(ci)矩(ju)形抄板(ban)內進(jin)行(xing)(xing)(xing)充分干(gan)燥,由此(ci)完(wan)成干(gan)燥目的(de)(de)。
