產品(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。
產品結構
三筒式烘干機(ji)(ji)是通過對單(dan)(dan)筒烘干機(ji)(ji)的(de)單(dan)(dan)筒體(ti)(ti)(ti)改為套疊在(zai)一(yi)起的(de)三筒,以縮短烘干機(ji)(ji)體(ti)(ti)(ti)的(de)外形尺(chi)寸。該機(ji)(ji)工作時,物料和熱(re)氣(qi)流(liu)依次進入內至(zhi)外筒體(ti)(ti)(ti),在(zai)機(ji)(ji)體(ti)(ti)(ti)Z形往復折流(liu)后,充分利用(yong)熱(re)能烘干物料后再卸出(chu)。
烘干機筒體部分(fen)由三個同(tong)軸水(shui)平放置的內(nei)、中、外筒套疊組成,這就使筒體的截面得到充分(fen)的利用。其筒體外形總長度約為(wei)與之相當的單筒的30-35%。從而大幅度地減(jian)少占地面積(ji)和廠房(fang)建筑面積(ji)。
該(gai)機(ji)的支承(cheng)裝置,是(shi)在外筒(tong)上輪帶(dai)(dai)與(yu)(yu)托輪支承(cheng),由(you)電機(ji)直接(jie)帶(dai)(dai)動托輪。通過托輪與(yu)(yu)輪帶(dai)(dai)摩擦,使筒(tong)體(ti)轉動。該(gai)機(ji)總體(ti)結構緊湊、合理(li)、簡單(dan),為便于磨損件的檢(jian)修更換,在中間(jian)設計(ji)成軸向剖分式,用螺(luo)栓固(gu)定連接(jie)。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)(liao)裝(zhuang)置進(jin)(jin)(jin)(jin)(jin)入回轉滾(gun)(gun)(gun)筒(tong)的(de)內(nei)層(ceng)(ceng)(ceng),實現(xian)順(shun)流(liu)烘干,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在內(nei)層(ceng)(ceng)(ceng)的(de)抄板下不斷(duan)抄起、散落(luo)呈螺旋行(xing)進(jin)(jin)(jin)(jin)(jin)式實現(xian)熱交換(huan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)的(de)另一(yi)端進(jin)(jin)(jin)(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)(jin)行(xing)逆流(liu)烘干,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)不斷(duan)地被(bei)反復揚進(jin)(jin)(jin)(jin)(jin),呈進(jin)(jin)(jin)(jin)(jin)兩步退(tui)一(yi)步的(de)行(xing)進(jin)(jin)(jin)(jin)(jin)方(fang)(fang)式,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)既(ji)充分(fen)吸收(shou)內(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)散發的(de)熱量(liang),又吸收(shou)中(zhong)層(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)的(de)熱量(liang),同時(shi)又延長了干燥(zao)(zao)(zao)時(shi)間,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在此達到干燥(zao)(zao)(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)(ceng)另一(yi)端而(er)落(luo)入外(wai)層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在外(wai)層(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)內(nei)呈矩(ju)(ju)形多回路(lu)方(fang)(fang)式行(xing)進(jin)(jin)(jin)(jin)(jin),達到干燥(zao)(zao)(zao)效(xiao)果的(de)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在熱風作用下快速(su)行(xing)進(jin)(jin)(jin)(jin)(jin)排出滾(gun)(gun)(gun)筒(tong),沒有(you)達到干燥(zao)(zao)(zao)效(xiao)果的(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因(yin)自重而(er)不能快速(su)行(xing)進(jin)(jin)(jin)(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在此矩(ju)(ju)形抄板內(nei)進(jin)(jin)(jin)(jin)(jin)行(xing)充分(fen)干燥(zao)(zao)(zao),由(you)此完成干燥(zao)(zao)(zao)目的(de)。
