產(chan)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)品結(jie)構
三(san)筒(tong)(tong)式烘(hong)(hong)干機(ji)(ji)是通過(guo)對(dui)單(dan)筒(tong)(tong)烘(hong)(hong)干機(ji)(ji)的(de)單(dan)筒(tong)(tong)體(ti)改(gai)為套疊(die)在(zai)一起的(de)三(san)筒(tong)(tong)，以縮短(duan)烘(hong)(hong)干機(ji)(ji)體(ti)的(de)外形(xing)尺寸。該機(ji)(ji)工作時(shi)，物料(liao)和熱氣流依次進(jin)入內(nei)至外筒(tong)(tong)體(ti)，在(zai)機(ji)(ji)體(ti)Z形(xing)往復折流后，充(chong)分利用熱能烘(hong)(hong)干物料(liao)后再卸出。
烘干(gan)機筒(tong)體(ti)部分由三(san)個同軸水(shui)平(ping)放置的內、中、外筒(tong)套疊組成，這就使筒(tong)體(ti)的截面(mian)得到充分的利(li)用(yong)。其筒(tong)體(ti)外形(xing)總長度約(yue)為(wei)與之相當的單筒(tong)的30-35%。從而大(da)幅(fu)度地減少占地面(mian)積和(he)廠房建筑(zhu)面(mian)積。
該機(ji)的支承裝置，是在外筒(tong)上(shang)輪帶與托輪支承，由電機(ji)直接帶動(dong)托輪。通過托輪與輪帶摩擦，使筒(tong)體(ti)轉(zhuan)動(dong)。該機(ji)總體(ti)結構緊湊(cou)、合理(li)、簡單，為便于磨損件(jian)的檢修更換(huan)，在中間設計(ji)成軸向(xiang)剖分式，用螺(luo)栓(shuan)固定連接。
工作(zuo)原理
物(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)入(ru)回(hui)轉滾筒的(de)(de)(de)內(nei)層(ceng)(ceng)(ceng),實現順(shun)流烘(hong)(hong)干(gan)(gan)(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)抄板下不(bu)斷抄起、散(san)落呈螺(luo)旋行(xing)(xing)(xing)(xing)進(jin)式(shi)實現熱(re)(re)交換，物(wu)(wu)(wu)(wu)料(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)另一端(duan)進(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng)，進(jin)行(xing)(xing)(xing)(xing)逆流烘(hong)(hong)干(gan)(gan)(gan)(gan)，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不(bu)斷地被反(fan)復揚進(jin)，呈進(jin)兩步(bu)退一步(bu)的(de)(de)(de)行(xing)(xing)(xing)(xing)進(jin)方式(shi)，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充(chong)分(fen)吸收內(nei)層(ceng)(ceng)(ceng)滾筒散(san)發的(de)(de)(de)熱(re)(re)量，又吸收中(zhong)(zhong)層(ceng)(ceng)(ceng)滾筒的(de)(de)(de)熱(re)(re)量，同(tong)時又延長了干(gan)(gan)(gan)(gan)燥(zao)時間(jian)，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)達到(dao)(dao)干(gan)(gan)(gan)(gan)燥(zao)狀(zhuang)態(tai)。物(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)另一端(duan)而落入(ru)外層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)滾筒內(nei)呈矩(ju)形多回(hui)路(lu)方式(shi)行(xing)(xing)(xing)(xing)進(jin)，達到(dao)(dao)干(gan)(gan)(gan)(gan)燥(zao)效果的(de)(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)熱(re)(re)風(feng)作(zuo)用下快速行(xing)(xing)(xing)(xing)進(jin)排(pai)出滾筒，沒有達到(dao)(dao)干(gan)(gan)(gan)(gan)燥(zao)效果的(de)(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)因自重(zhong)而不(bu)能快速行(xing)(xing)(xing)(xing)進(jin)，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)矩(ju)形抄板內(nei)進(jin)行(xing)(xing)(xing)(xing)充(chong)分(fen)干(gan)(gan)(gan)(gan)燥(zao)，由此(ci)完成(cheng)干(gan)(gan)(gan)(gan)燥(zao)目的(de)(de)(de)。
