產品(pin)概(gai)況
回轉式三筒烘(hong)干機(ji)改進原(yuan)單筒烘(hong)干機(ji)內部結構，增加(jia)入機(ji)前濕料(liao)的預烘(hong)干和延長(chang)濕料(liao)在機(ji)內烘(hong)干時間，再加(jia)上密封、保溫以及合理的配(pei)套措施(shi)，使烘(hong)干機(ji)生產能力與原(yuan)單筒式烘(hong)干機(ji)相比，提(ti)高(gao)48-80%，單位容(rong)積蒸發強度(du)可達120-180kg/m3，標準煤耗僅為6-8kg/t。其(qi)技術先進、運行(xing)參(can)數合理，操作簡(jian)單可行(xing)，廣(guang)泛(fan)應用于各個(ge)行(xing)業的礦渣、粘土(tu)、煤。
產品結構
三筒(tong)(tong)(tong)烘(hong)(hong)干(gan)機是通(tong)過對單(dan)筒(tong)(tong)(tong)烘(hong)(hong)干(gan)機的單(dan)筒(tong)(tong)(tong)體(ti)改為套疊在一起的三筒(tong)(tong)(tong)，以縮短烘(hong)(hong)干(gan)機體(ti)的外形(xing)尺(chi)寸(cun)。該機工作(zuo)時，物料和(he)熱氣流(liu)依次進入(ru)內至外筒(tong)(tong)(tong)體(ti)，在機體(ti)Z形(xing)往復折(zhe)流(liu)后，充分利用(yong)熱能烘(hong)(hong)干(gan)物料后再(zai)卸出。
烘干機筒(tong)體部分由(you)三(san)個同軸水(shui)平放置的內(nei)、中(zhong)、外(wai)筒(tong)套疊組成，這就使筒(tong)體的截(jie)面得到(dao)充(chong)分的利用。其筒(tong)體外(wai)形(xing)總長度(du)約(yue)為(wei)與之相當(dang)的單筒(tong)的30-35%。從而大幅度(du)地(di)減少占地(di)面積(ji)和廠房(fang)建筑面積(ji)。
該(gai)機(ji)的(de)支承(cheng)裝置，是(shi)在外筒上輪(lun)帶(dai)與托輪(lun)支承(cheng)，由電(dian)機(ji)直接帶(dai)動托輪(lun)。通(tong)過托輪(lun)與輪(lun)帶(dai)摩擦，使(shi)筒體轉動。該(gai)機(ji)總體結構(gou)緊(jin)湊、合理、簡單，為(wei)便(bian)于磨損件的(de)檢(jian)修更換(huan)，在中間設計(ji)成(cheng)軸(zhou)向剖(pou)分式，用螺栓固定(ding)連接。
工作原理
物(wu)料(liao)(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)(liao)裝置進入回轉(zhuan)滾(gun)筒(tong)的內(nei)層(ceng)(ceng)(ceng),實現順流(liu)烘(hong)干(gan),物(wu)料(liao)(liao)(liao)(liao)(liao)在內(nei)層(ceng)(ceng)(ceng)的抄板下不(bu)斷(duan)抄起(qi)、散落呈螺旋(xuan)行(xing)進式實現熱交換，物(wu)料(liao)(liao)(liao)(liao)(liao)移(yi)動至(zhi)內(nei)層(ceng)(ceng)(ceng)的另(ling)一端(duan)進入中(zhong)層(ceng)(ceng)(ceng)，進行(xing)逆(ni)流(liu)烘(hong)干(gan)，物(wu)料(liao)(liao)(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)不(bu)斷(duan)地(di)被(bei)反復揚進，呈進兩步(bu)退一步(bu)的行(xing)進方式，物(wu)料(liao)(liao)(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)既(ji)充(chong)分吸收(shou)內(nei)層(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的熱量，又吸收(shou)中(zhong)層(ceng)(ceng)(ceng)滾(gun)筒(tong)的熱量，同時又延(yan)長了干(gan)燥(zao)(zao)時間，物(wu)料(liao)(liao)(liao)(liao)(liao)在此(ci)達到干(gan)燥(zao)(zao)狀態(tai)。物(wu)料(liao)(liao)(liao)(liao)(liao)行(xing)至(zhi)中(zhong)層(ceng)(ceng)(ceng)另(ling)一端(duan)而落入外(wai)層(ceng)(ceng)(ceng)，物(wu)料(liao)(liao)(liao)(liao)(liao)在外(wai)層(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)呈矩形(xing)多(duo)回路方式行(xing)進，達到干(gan)燥(zao)(zao)效(xiao)果(guo)(guo)的物(wu)料(liao)(liao)(liao)(liao)(liao)在熱風作用(yong)下快(kuai)速行(xing)進排出滾(gun)筒(tong)，沒(mei)有達到干(gan)燥(zao)(zao)效(xiao)果(guo)(guo)的濕物(wu)料(liao)(liao)(liao)(liao)(liao)因自重而不(bu)能快(kuai)速行(xing)進，物(wu)料(liao)(liao)(liao)(liao)(liao)在此(ci)矩形(xing)抄板內(nei)進行(xing)充(chong)分干(gan)燥(zao)(zao)，由此(ci)完成干(gan)燥(zao)(zao)目的。
