產品概況
回轉式三筒烘(hong)(hong)干(gan)機(ji)改進原單筒烘(hong)(hong)干(gan)機(ji)內部結構，增加(jia)入機(ji)前(qian)濕料(liao)的(de)預(yu)烘(hong)(hong)干(gan)和延(yan)長濕料(liao)在機(ji)內烘(hong)(hong)干(gan)時間，再(zai)加(jia)上密封、保溫以及合(he)理的(de)配(pei)套(tao)措施，使(shi)烘(hong)(hong)干(gan)機(ji)生(sheng)產能力(li)與(yu)原單筒式烘(hong)(hong)干(gan)機(ji)相比，提高48-80%，單位容積(ji)蒸發強度可達120-180kg/m3，標準(zhun)煤(mei)耗僅(jin)為6-8kg/t。其技術先(xian)進、運行參數合(he)理，操作簡單可行，廣泛應用(yong)于(yu)各個行業的(de)礦渣、粘土、煤(mei)。
產品結構
三(san)筒(tong)烘干機(ji)(ji)是通過(guo)對單筒(tong)烘干機(ji)(ji)的單筒(tong)體改為(wei)套(tao)疊在(zai)一起(qi)的三(san)筒(tong)，以縮短烘干機(ji)(ji)體的外形尺寸。該機(ji)(ji)工作(zuo)時，物料和熱氣(qi)流(liu)依(yi)次進入(ru)內至外筒(tong)體，在(zai)機(ji)(ji)體Z形往復折流(liu)后(hou)，充分利用(yong)熱能烘干物料后(hou)再卸出。
烘干機筒(tong)(tong)體部分由三個同軸水平放置的(de)內、中、外(wai)筒(tong)(tong)套疊(die)組成，這(zhe)就使筒(tong)(tong)體的(de)截(jie)面(mian)得到(dao)充分的(de)利用。其筒(tong)(tong)體外(wai)形總長度約為與之相當的(de)單筒(tong)(tong)的(de)30-35%。從而(er)大幅(fu)度地(di)減少占(zhan)地(di)面(mian)積和廠房(fang)建筑面(mian)積。
該機(ji)的支(zhi)承(cheng)裝(zhuang)置(zhi)，是在外筒上輪(lun)(lun)帶與托輪(lun)(lun)支(zhi)承(cheng)，由電機(ji)直接(jie)帶動托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶摩(mo)擦，使筒體轉(zhuan)動。該機(ji)總體結(jie)構緊(jin)湊、合理、簡單，為便于磨損件的檢修更(geng)換(huan)，在中間設計(ji)成軸向剖(pou)分式(shi)，用(yong)螺(luo)栓固定連接(jie)。
工作原(yuan)理
物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝(zhuang)置進(jin)入回轉滾筒(tong)(tong)的內層,實現順流烘干,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)內層的抄板下(xia)不斷(duan)抄起、散(san)落(luo)呈螺(luo)旋行(xing)進(jin)式實現熱交換，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)移動(dong)至(zhi)內層的另一(yi)端進(jin)入中(zhong)(zhong)層，進(jin)行(xing)逆流烘干，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層不斷(duan)地被反復揚(yang)進(jin)，呈進(jin)兩(liang)步退一(yi)步的行(xing)進(jin)方式，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層既(ji)充分吸(xi)收(shou)內層滾筒(tong)(tong)散(san)發的熱量，又吸(xi)收(shou)中(zhong)(zhong)層滾筒(tong)(tong)的熱量，同時又延長了干燥(zao)時間(jian)，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)(ci)達到干燥(zao)狀態。物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)至(zhi)中(zhong)(zhong)層另一(yi)端而落(luo)入外層，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)外層滾筒(tong)(tong)內呈矩形多回路(lu)方式行(xing)進(jin)，達到干燥(zao)效果的物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)熱風(feng)作用下(xia)快速行(xing)進(jin)排出滾筒(tong)(tong)，沒有達到干燥(zao)效果的濕物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)因自重而不能快速行(xing)進(jin)，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)(ci)矩形抄板內進(jin)行(xing)充分干燥(zao)，由此(ci)(ci)完(wan)成(cheng)干燥(zao)目的。
