產品(pin)概(gai)況(kuang)
回(hui)轉式三筒(tong)烘(hong)(hong)(hong)干機改進原單(dan)(dan)筒(tong)烘(hong)(hong)(hong)干機內部(bu)結構(gou)，增加入機前濕料(liao)的預烘(hong)(hong)(hong)干和延長(chang)濕料(liao)在機內烘(hong)(hong)(hong)干時(shi)間(jian)，再加上(shang)密封、保溫(wen)以及合理的配套措施，使烘(hong)(hong)(hong)干機生產能力與原單(dan)(dan)筒(tong)式烘(hong)(hong)(hong)干機相比，提高48-80%，單(dan)(dan)位容積(ji)蒸發強度可達120-180kg/m3，標準(zhun)煤耗僅(jin)為6-8kg/t。其技術先進、運行參數(shu)合理，操作簡單(dan)(dan)可行，廣泛應用(yong)于各個(ge)行業的礦渣(zha)、粘土(tu)、煤。
產品結構
三筒(tong)烘(hong)干(gan)(gan)(gan)機是通過(guo)對單筒(tong)烘(hong)干(gan)(gan)(gan)機的單筒(tong)體(ti)改為套疊在一起的三筒(tong)，以縮(suo)短烘(hong)干(gan)(gan)(gan)機體(ti)的外形尺寸(cun)。該機工作時，物(wu)料和熱(re)氣流(liu)依次(ci)進入內至外筒(tong)體(ti)，在機體(ti)Z形往復(fu)折(zhe)流(liu)后，充分利(li)用熱(re)能(neng)烘(hong)干(gan)(gan)(gan)物(wu)料后再卸出。
烘干機筒(tong)體部分由三個同軸水平放(fang)置的(de)(de)內、中、外筒(tong)套疊組成，這(zhe)就使筒(tong)體的(de)(de)截面(mian)(mian)(mian)得到充分的(de)(de)利(li)用。其筒(tong)體外形總(zong)長度約為與之(zhi)相(xiang)當的(de)(de)單(dan)筒(tong)的(de)(de)30-35%。從而(er)大(da)幅(fu)度地減少占地面(mian)(mian)(mian)積和(he)廠房建筑面(mian)(mian)(mian)積。
該機(ji)的(de)支承(cheng)裝置，是在(zai)外筒上輪(lun)帶與托輪(lun)支承(cheng)，由電機(ji)直接(jie)帶動(dong)托輪(lun)。通(tong)過托輪(lun)與輪(lun)帶摩擦，使筒體轉(zhuan)動(dong)。該機(ji)總體結構(gou)緊湊(cou)、合理、簡單，為便于磨(mo)損件(jian)的(de)檢修更換，在(zai)中間(jian)設計成軸向(xiang)剖分式，用螺栓固定連(lian)接(jie)。
工作(zuo)原理
物(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)入回轉滾(gun)(gun)(gun)筒(tong)(tong)的(de)(de)內層(ceng)(ceng),實(shi)現順(shun)流烘干(gan)(gan),物(wu)(wu)料(liao)(liao)在(zai)(zai)內層(ceng)(ceng)的(de)(de)抄板(ban)下不斷抄起(qi)、散(san)落(luo)呈(cheng)螺旋行(xing)(xing)進(jin)(jin)(jin)式(shi)實(shi)現熱交換，物(wu)(wu)料(liao)(liao)移動至內層(ceng)(ceng)的(de)(de)另(ling)一端進(jin)(jin)(jin)入中層(ceng)(ceng)，進(jin)(jin)(jin)行(xing)(xing)逆流烘干(gan)(gan)，物(wu)(wu)料(liao)(liao)在(zai)(zai)中層(ceng)(ceng)不斷地(di)被反復揚(yang)進(jin)(jin)(jin)，呈(cheng)進(jin)(jin)(jin)兩(liang)步(bu)退一步(bu)的(de)(de)行(xing)(xing)進(jin)(jin)(jin)方式(shi)，物(wu)(wu)料(liao)(liao)在(zai)(zai)中層(ceng)(ceng)既充(chong)分(fen)吸收內層(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)散(san)發(fa)的(de)(de)熱量，又(you)吸收中層(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)的(de)(de)熱量，同時(shi)又(you)延(yan)長了干(gan)(gan)燥時(shi)間，物(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)達到(dao)干(gan)(gan)燥狀態(tai)。物(wu)(wu)料(liao)(liao)行(xing)(xing)至中層(ceng)(ceng)另(ling)一端而落(luo)入外層(ceng)(ceng)，物(wu)(wu)料(liao)(liao)在(zai)(zai)外層(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)內呈(cheng)矩(ju)形多(duo)回路(lu)方式(shi)行(xing)(xing)進(jin)(jin)(jin)，達到(dao)干(gan)(gan)燥效果的(de)(de)物(wu)(wu)料(liao)(liao)在(zai)(zai)熱風作用下快速(su)行(xing)(xing)進(jin)(jin)(jin)排出滾(gun)(gun)(gun)筒(tong)(tong)，沒(mei)有(you)達到(dao)干(gan)(gan)燥效果的(de)(de)濕物(wu)(wu)料(liao)(liao)因(yin)自重而不能快速(su)行(xing)(xing)進(jin)(jin)(jin)，物(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)矩(ju)形抄板(ban)內進(jin)(jin)(jin)行(xing)(xing)充(chong)分(fen)干(gan)(gan)燥，由此(ci)完(wan)成干(gan)(gan)燥目的(de)(de)。
