產品概況
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(chan)品(pin)結構(gou)
三筒式烘(hong)干機(ji)是(shi)通(tong)過對單筒烘(hong)干機(ji)的(de)單筒體(ti)(ti)改為套(tao)疊在一起的(de)三筒，以縮短(duan)烘(hong)干機(ji)體(ti)(ti)的(de)外形(xing)尺寸。該(gai)機(ji)工作(zuo)時(shi)，物料和熱氣流依(yi)次進入內至外筒體(ti)(ti)，在機(ji)體(ti)(ti)Z形(xing)往復(fu)折流后，充分(fen)利用(yong)熱能烘(hong)干物料后再卸出。
烘干(gan)機筒(tong)(tong)體部分由(you)三個同(tong)軸水平放置的內、中、外(wai)筒(tong)(tong)套疊組成，這就(jiu)使筒(tong)(tong)體的截面得到充分的利用。其(qi)筒(tong)(tong)體外(wai)形總長度約為與之(zhi)相當的單筒(tong)(tong)的30-35%。從而(er)大幅度地減少占(zhan)地面積和廠(chang)房建筑面積。
該(gai)機的(de)支(zhi)(zhi)承裝置，是在外筒上輪(lun)帶與托(tuo)輪(lun)支(zhi)(zhi)承，由(you)電機直接(jie)帶動托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶摩(mo)擦，使筒體轉動。該(gai)機總體結構緊湊(cou)、合理、簡單，為便于(yu)磨損件(jian)的(de)檢修更(geng)換，在中間(jian)設計成軸向剖分式，用螺栓固定連接(jie)。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝置進(jin)入回轉滾(gun)筒(tong)的內(nei)(nei)層(ceng)(ceng)(ceng)(ceng),實現順流(liu)烘干(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的抄板(ban)下不(bu)斷(duan)抄起(qi)、散落呈(cheng)螺(luo)旋行(xing)進(jin)式(shi)實現熱(re)交換，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移動至內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的另一(yi)端(duan)(duan)進(jin)入中(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)行(xing)逆流(liu)烘干(gan)(gan)，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷(duan)地被反復揚進(jin)，呈(cheng)進(jin)兩(liang)步退一(yi)步的行(xing)進(jin)方式(shi)，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分(fen)吸(xi)收內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的熱(re)量，又吸(xi)收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)的熱(re)量，同(tong)時又延(yan)長了干(gan)(gan)燥時間，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)達到干(gan)(gan)燥狀(zhuang)態。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另一(yi)端(duan)(duan)而落入外層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)(nei)呈(cheng)矩(ju)形多回路方式(shi)行(xing)進(jin)，達到干(gan)(gan)燥效(xiao)果的物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)熱(re)風作用下快速行(xing)進(jin)排出滾(gun)筒(tong)，沒有達到干(gan)(gan)燥效(xiao)果的濕物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因自重而不(bu)能快速行(xing)進(jin)，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)矩(ju)形抄板(ban)內(nei)(nei)進(jin)行(xing)充分(fen)干(gan)(gan)燥，由此(ci)完(wan)成干(gan)(gan)燥目的。
