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。
產品(pin)結構
三筒式烘干(gan)機(ji)(ji)是(shi)通過對單筒烘干(gan)機(ji)(ji)的(de)單筒體(ti)(ti)改為套疊在(zai)一(yi)起(qi)的(de)三筒,以縮短(duan)烘干(gan)機(ji)(ji)體(ti)(ti)的(de)外形尺寸。該(gai)機(ji)(ji)工(gong)作時,物料(liao)和(he)熱氣流(liu)依(yi)次進入內至外筒體(ti)(ti),在(zai)機(ji)(ji)體(ti)(ti)Z形往復折(zhe)流(liu)后,充分(fen)利用熱能烘干(gan)物料(liao)后再卸出。
烘干機筒(tong)(tong)體部分由三個同(tong)軸水平(ping)放置的(de)(de)(de)內、中、外(wai)(wai)筒(tong)(tong)套疊組成(cheng),這就使(shi)筒(tong)(tong)體的(de)(de)(de)截面得(de)到充分的(de)(de)(de)利(li)用。其筒(tong)(tong)體外(wai)(wai)形(xing)總長度(du)約為與之相當的(de)(de)(de)單(dan)筒(tong)(tong)的(de)(de)(de)30-35%。從而大幅度(du)地減少占地面積和廠(chang)房建筑(zhu)面積。
該機的(de)支承裝(zhuang)置,是在(zai)外筒上(shang)輪(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)支承,由電機直接(jie)帶(dai)動托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使筒體(ti)(ti)轉(zhuan)動。該機總(zong)體(ti)(ti)結構(gou)緊湊(cou)、合理、簡單,為便于磨損件的(de)檢修更換,在(zai)中間設計成軸向剖分式,用螺(luo)栓固定連(lian)接(jie)。
工作原理
物(wu)(wu)(wu)(wu)(wu)料由(you)供料裝置(zhi)進(jin)(jin)入(ru)回轉滾(gun)(gun)筒(tong)的內(nei)層(ceng)(ceng)(ceng),實現順流烘干(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料在(zai)(zai)(zai)內(nei)層(ceng)(ceng)(ceng)的抄(chao)板(ban)下不(bu)(bu)斷(duan)抄(chao)起(qi)、散(san)落呈(cheng)螺旋行(xing)進(jin)(jin)式(shi)實現熱(re)(re)交(jiao)換,物(wu)(wu)(wu)(wu)(wu)料移(yi)動至內(nei)層(ceng)(ceng)(ceng)的另(ling)一(yi)端進(jin)(jin)入(ru)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)行(xing)逆(ni)流烘干(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料在(zai)(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)不(bu)(bu)斷(duan)地被反復揚進(jin)(jin),呈(cheng)進(jin)(jin)兩步退一(yi)步的行(xing)進(jin)(jin)方(fang)式(shi),物(wu)(wu)(wu)(wu)(wu)料在(zai)(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)既充分(fen)吸收(shou)內(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散(san)發(fa)的熱(re)(re)量,又吸收(shou)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的熱(re)(re)量,同時又延長了(le)干(gan)(gan)燥(zao)(zao)時間,物(wu)(wu)(wu)(wu)(wu)料在(zai)(zai)(zai)此達(da)到干(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)(wu)(wu)料行(xing)至中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)另(ling)一(yi)端而(er)(er)落入(ru)外層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)料在(zai)(zai)(zai)外層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)呈(cheng)矩形多回路方(fang)式(shi)行(xing)進(jin)(jin),達(da)到干(gan)(gan)燥(zao)(zao)效(xiao)果的物(wu)(wu)(wu)(wu)(wu)料在(zai)(zai)(zai)熱(re)(re)風(feng)作用下快速行(xing)進(jin)(jin)排出滾(gun)(gun)筒(tong),沒有達(da)到干(gan)(gan)燥(zao)(zao)效(xiao)果的濕物(wu)(wu)(wu)(wu)(wu)料因自(zi)重而(er)(er)不(bu)(bu)能快速行(xing)進(jin)(jin),物(wu)(wu)(wu)(wu)(wu)料在(zai)(zai)(zai)此矩形抄(chao)板(ban)內(nei)進(jin)(jin)行(xing)充分(fen)干(gan)(gan)燥(zao)(zao),由(you)此完成干(gan)(gan)燥(zao)(zao)目(mu)的。
