產品(pin)概況
回轉式三(san)筒(tong)(tong)烘(hong)(hong)(hong)干(gan)機(ji)(ji)改(gai)進原單筒(tong)(tong)烘(hong)(hong)(hong)干(gan)機(ji)(ji)內部(bu)結(jie)構，增(zeng)加(jia)入機(ji)(ji)前濕(shi)料的(de)預烘(hong)(hong)(hong)干(gan)和延(yan)長濕(shi)料在機(ji)(ji)內烘(hong)(hong)(hong)干(gan)時(shi)間，再加(jia)上(shang)密封、保溫以及(ji)合理(li)的(de)配(pei)套措施，使烘(hong)(hong)(hong)干(gan)機(ji)(ji)生(sheng)產能力與原單筒(tong)(tong)式烘(hong)(hong)(hong)干(gan)機(ji)(ji)相比(bi)，提高48-80%，單位容積(ji)蒸發強度可達120-180kg/m3，標準煤耗僅為(wei)6-8kg/t。其技術先進、運行參數合理(li)，操作簡單可行，廣(guang)泛應用于各(ge)個行業的(de)礦(kuang)渣、粘土(tu)、煤。
產品結構(gou)
三筒(tong)烘(hong)干(gan)機(ji)是通(tong)過(guo)對單筒(tong)烘(hong)干(gan)機(ji)的(de)(de)單筒(tong)體改為套疊在一起的(de)(de)三筒(tong)，以縮短(duan)烘(hong)干(gan)機(ji)體的(de)(de)外(wai)形尺寸(cun)。該機(ji)工作時，物料和熱氣流(liu)依次進入內至外(wai)筒(tong)體，在機(ji)體Z形往(wang)復折流(liu)后(hou)，充分利用(yong)熱能烘(hong)干(gan)物料后(hou)再卸出。
烘干機筒(tong)體(ti)(ti)部分(fen)由三個同軸水平放置的內、中、外筒(tong)套疊組成，這就使筒(tong)體(ti)(ti)的截面(mian)得到充(chong)分(fen)的利用。其筒(tong)體(ti)(ti)外形總長度約為(wei)與之相當的單(dan)筒(tong)的30-35%。從而(er)大幅度地減少(shao)占地面(mian)積和廠房建筑(zhu)面(mian)積。
該機(ji)(ji)(ji)的支承(cheng)裝置，是在外(wai)筒上輪帶(dai)(dai)與托輪支承(cheng)，由電(dian)機(ji)(ji)(ji)直接(jie)帶(dai)(dai)動托輪。通過托輪與輪帶(dai)(dai)摩擦，使筒體轉(zhuan)動。該機(ji)(ji)(ji)總體結構緊(jin)湊、合理、簡單(dan)，為(wei)便于磨(mo)損件的檢修更(geng)換，在中間(jian)設計成軸向剖分式，用(yong)螺栓固(gu)定連接(jie)。
工作(zuo)原(yuan)理
物料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)入回(hui)轉滾(gun)(gun)筒(tong)的(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實現(xian)順流烘干(gan),物料(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)抄(chao)板下(xia)不斷抄(chao)起、散落呈(cheng)螺(luo)旋(xuan)行(xing)進(jin)(jin)式實現(xian)熱交換，物料(liao)(liao)移(yi)動至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)另一端(duan)進(jin)(jin)入中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)逆流烘干(gan)，物料(liao)(liao)在(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)不斷地被(bei)反復揚進(jin)(jin)，呈(cheng)進(jin)(jin)兩步(bu)退一步(bu)的(de)行(xing)進(jin)(jin)方(fang)式，物料(liao)(liao)在(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)既(ji)充(chong)分(fen)吸(xi)收內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散發的(de)熱量，又吸(xi)收中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)熱量，同時又延長了干(gan)燥時間，物料(liao)(liao)在(zai)(zai)此達到(dao)(dao)干(gan)燥狀態(tai)。物料(liao)(liao)行(xing)至中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)另一端(duan)而(er)落入外層(ceng)(ceng)(ceng)(ceng)，物料(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)呈(cheng)矩(ju)形(xing)多(duo)回(hui)路(lu)方(fang)式行(xing)進(jin)(jin)，達到(dao)(dao)干(gan)燥效(xiao)果的(de)物料(liao)(liao)在(zai)(zai)熱風(feng)作用下(xia)快(kuai)速(su)行(xing)進(jin)(jin)排(pai)出滾(gun)(gun)筒(tong)，沒(mei)有達到(dao)(dao)干(gan)燥效(xiao)果的(de)濕物料(liao)(liao)因(yin)自重(zhong)而(er)不能快(kuai)速(su)行(xing)進(jin)(jin)，物料(liao)(liao)在(zai)(zai)此矩(ju)形(xing)抄(chao)板內(nei)進(jin)(jin)行(xing)充(chong)分(fen)干(gan)燥，由此完成干(gan)燥目(mu)的(de)。
