產品概況(kuang)
回轉式三筒(tong)烘干(gan)機改進原單筒(tong)烘干(gan)機內部結構，增(zeng)加入機前濕料(liao)的預(yu)烘干(gan)和(he)延長濕料(liao)在機內烘干(gan)時間，再(zai)加上密封(feng)、保(bao)溫以及合理(li)的配套措施(shi)，使烘干(gan)機生產能力與(yu)原單筒(tong)式烘干(gan)機相比，提高48-80%，單位容積蒸發(fa)強度可達(da)120-180kg/m3，標準煤耗僅(jin)為6-8kg/t。其技術先(xian)進、運行(xing)參數合理(li)，操作簡(jian)單可行(xing)，廣泛應用于各(ge)個行(xing)業(ye)的礦渣、粘土、煤。
產品結(jie)構
三(san)筒(tong)(tong)(tong)烘(hong)干(gan)機(ji)是通過對單(dan)(dan)筒(tong)(tong)(tong)烘(hong)干(gan)機(ji)的(de)單(dan)(dan)筒(tong)(tong)(tong)體改(gai)為套疊在一起的(de)三(san)筒(tong)(tong)(tong)，以縮短(duan)烘(hong)干(gan)機(ji)體的(de)外形尺寸。該機(ji)工作時，物料和熱氣流依(yi)次(ci)進入(ru)內至外筒(tong)(tong)(tong)體，在機(ji)體Z形往復折流后(hou)，充(chong)分利用熱能烘(hong)干(gan)物料后(hou)再卸出(chu)。
烘干機筒(tong)體(ti)部分由(you)三個(ge)同(tong)軸水平放置的內(nei)、中、外筒(tong)套疊組成，這就(jiu)使筒(tong)體(ti)的截面得(de)到充分的利(li)用(yong)。其筒(tong)體(ti)外形總長(chang)度約為與之相(xiang)當的單(dan)筒(tong)的30-35%。從而(er)大(da)幅度地減(jian)少占地面積和廠房建(jian)筑面積。
該(gai)機(ji)的(de)支承(cheng)裝(zhuang)置，是在外筒上輪(lun)帶(dai)與托輪(lun)支承(cheng)，由(you)電機(ji)直接帶(dai)動托輪(lun)。通過托輪(lun)與輪(lun)帶(dai)摩擦，使筒體(ti)轉動。該(gai)機(ji)總(zong)體(ti)結(jie)構緊湊、合理、簡單(dan)，為便于磨損(sun)件的(de)檢修更換，在中間設計成(cheng)軸向剖分(fen)式，用螺栓固定連(lian)接。
工作原理
物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝(zhuang)置進(jin)(jin)(jin)(jin)入回轉滾筒的內層(ceng)(ceng)(ceng),實現順流烘干(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在內層(ceng)(ceng)(ceng)的抄(chao)板下不斷抄(chao)起、散落呈螺旋行進(jin)(jin)(jin)(jin)式實現熱(re)交換，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移動至(zhi)內層(ceng)(ceng)(ceng)的另(ling)一端進(jin)(jin)(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)(jin)(jin)行逆流烘干(gan)，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)(ceng)不斷地(di)被(bei)反(fan)復揚進(jin)(jin)(jin)(jin)，呈進(jin)(jin)(jin)(jin)兩步退一步的行進(jin)(jin)(jin)(jin)方式，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)(ceng)既充(chong)分吸收(shou)(shou)內層(ceng)(ceng)(ceng)滾筒散發(fa)的熱(re)量，又吸收(shou)(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)滾筒的熱(re)量，同時(shi)又延(yan)長了干(gan)燥(zao)(zao)(zao)時(shi)間，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在此(ci)達到干(gan)燥(zao)(zao)(zao)狀態。物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行至(zhi)中(zhong)(zhong)層(ceng)(ceng)(ceng)另(ling)一端而落入外(wai)層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在外(wai)層(ceng)(ceng)(ceng)滾筒內呈矩形(xing)多回路方式行進(jin)(jin)(jin)(jin)，達到干(gan)燥(zao)(zao)(zao)效果的物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在熱(re)風作用下快速行進(jin)(jin)(jin)(jin)排出滾筒，沒有達到干(gan)燥(zao)(zao)(zao)效果的濕物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因自重(zhong)而不能快速行進(jin)(jin)(jin)(jin)，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在此(ci)矩形(xing)抄(chao)板內進(jin)(jin)(jin)(jin)行充(chong)分干(gan)燥(zao)(zao)(zao)，由此(ci)完成(cheng)干(gan)燥(zao)(zao)(zao)目的。
