產品(pin)概況
回轉式(shi)三(san)筒(tong)烘(hong)干機改進原單(dan)筒(tong)烘(hong)干機內部結構,增加入機前(qian)濕料(liao)的預(yu)烘(hong)干和延長濕料(liao)在機內烘(hong)干時間(jian),再(zai)加上(shang)密封、保溫(wen)以及(ji)合理的配套措施,使烘(hong)干機生產能(neng)力與原單(dan)筒(tong)式(shi)烘(hong)干機相(xiang)比(bi),提高48-80%,單(dan)位容積蒸發強度可(ke)達(da)120-180kg/m3,標準煤耗僅為6-8kg/t。其技術先進、運行(xing)參數合理,操作(zuo)簡(jian)單(dan)可(ke)行(xing),廣泛應(ying)用于各個行(xing)業的礦(kuang)渣、粘土(tu)、煤。
產品結構
三筒(tong)(tong)烘(hong)(hong)干機(ji)是通(tong)過(guo)對(dui)單(dan)(dan)筒(tong)(tong)烘(hong)(hong)干機(ji)的單(dan)(dan)筒(tong)(tong)體改為套疊在一起的三筒(tong)(tong),以(yi)縮短烘(hong)(hong)干機(ji)體的外(wai)形(xing)尺(chi)寸。該機(ji)工作時,物料和熱(re)氣流依(yi)次進入內至外(wai)筒(tong)(tong)體,在機(ji)體Z形(xing)往復折(zhe)流后(hou),充分利用熱(re)能烘(hong)(hong)干物料后(hou)再卸出。
烘干機筒(tong)體(ti)(ti)(ti)部(bu)分由三(san)個同軸水平放置(zhi)的(de)內、中(zhong)、外筒(tong)套疊組成,這就(jiu)使筒(tong)體(ti)(ti)(ti)的(de)截面得到(dao)充(chong)分的(de)利(li)用。其(qi)筒(tong)體(ti)(ti)(ti)外形總(zong)長(chang)度(du)約為(wei)與之相當的(de)單筒(tong)的(de)30-35%。從而(er)大(da)幅度(du)地減少占地面積(ji)和(he)廠房建(jian)筑面積(ji)。
該機(ji)的支承裝(zhuang)置,是在(zai)外(wai)筒上輪(lun)帶(dai)與托(tuo)輪(lun)支承,由(you)電機(ji)直(zhi)接帶(dai)動托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶(dai)摩擦,使筒體轉動。該機(ji)總體結構緊(jin)湊、合理、簡單,為(wei)便于(yu)磨(mo)損(sun)件(jian)的檢修更換,在(zai)中(zhong)間(jian)設計成軸向剖分式,用螺栓固定連接。
工(gong)作原理
物(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置進(jin)(jin)(jin)入回(hui)(hui)轉滾(gun)(gun)筒的(de)(de)內(nei)(nei)層(ceng)(ceng),實現(xian)順流烘干(gan)(gan)(gan),物(wu)料(liao)(liao)(liao)在(zai)內(nei)(nei)層(ceng)(ceng)的(de)(de)抄(chao)板下(xia)不斷抄(chao)起、散(san)落(luo)呈螺旋行(xing)進(jin)(jin)(jin)式實現(xian)熱交換,物(wu)料(liao)(liao)(liao)移動至內(nei)(nei)層(ceng)(ceng)的(de)(de)另一端進(jin)(jin)(jin)入中層(ceng)(ceng),進(jin)(jin)(jin)行(xing)逆(ni)流烘干(gan)(gan)(gan),物(wu)料(liao)(liao)(liao)在(zai)中層(ceng)(ceng)不斷地被反(fan)復揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩步(bu)(bu)退一步(bu)(bu)的(de)(de)行(xing)進(jin)(jin)(jin)方式,物(wu)料(liao)(liao)(liao)在(zai)中層(ceng)(ceng)既充分(fen)吸(xi)收內(nei)(nei)層(ceng)(ceng)滾(gun)(gun)筒散(san)發的(de)(de)熱量,又吸(xi)收中層(ceng)(ceng)滾(gun)(gun)筒的(de)(de)熱量,同時又延長了干(gan)(gan)(gan)燥(zao)(zao)時間(jian),物(wu)料(liao)(liao)(liao)在(zai)此達到(dao)干(gan)(gan)(gan)燥(zao)(zao)狀態(tai)。物(wu)料(liao)(liao)(liao)行(xing)至中層(ceng)(ceng)另一端而(er)(er)落(luo)入外層(ceng)(ceng),物(wu)料(liao)(liao)(liao)在(zai)外層(ceng)(ceng)滾(gun)(gun)筒內(nei)(nei)呈矩形多回(hui)(hui)路方式行(xing)進(jin)(jin)(jin),達到(dao)干(gan)(gan)(gan)燥(zao)(zao)效果的(de)(de)物(wu)料(liao)(liao)(liao)在(zai)熱風作(zuo)用下(xia)快速(su)行(xing)進(jin)(jin)(jin)排出滾(gun)(gun)筒,沒有達到(dao)干(gan)(gan)(gan)燥(zao)(zao)效果的(de)(de)濕(shi)物(wu)料(liao)(liao)(liao)因(yin)自重而(er)(er)不能(neng)快速(su)行(xing)進(jin)(jin)(jin),物(wu)料(liao)(liao)(liao)在(zai)此矩形抄(chao)板內(nei)(nei)進(jin)(jin)(jin)行(xing)充分(fen)干(gan)(gan)(gan)燥(zao)(zao),由此完成干(gan)(gan)(gan)燥(zao)(zao)目的(de)(de)。
