產品概(gai)況(kuang)
回轉(zhuan)式三(san)筒(tong)(tong)烘干(gan)機改進原(yuan)單筒(tong)(tong)烘干(gan)機內部結(jie)構,增加入機前濕料的(de)預(yu)烘干(gan)和延長濕料在機內烘干(gan)時間(jian),再(zai)加上密封(feng)、保(bao)溫以及合理(li)的(de)配套措施,使烘干(gan)機生(sheng)產(chan)能力與(yu)原(yuan)單筒(tong)(tong)式烘干(gan)機相(xiang)比,提(ti)高48-80%,單位容(rong)積(ji)蒸發強(qiang)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(li),操(cao)作簡單可行,廣泛應用于各個行業的(de)礦渣、粘(zhan)土、煤。
產品結構
三筒(tong)烘干機(ji)(ji)是(shi)通過對單(dan)(dan)筒(tong)烘干機(ji)(ji)的(de)單(dan)(dan)筒(tong)體改為套(tao)疊在一起的(de)三筒(tong),以縮短烘干機(ji)(ji)體的(de)外形尺寸。該(gai)機(ji)(ji)工作時,物料(liao)和熱(re)氣(qi)流(liu)依次進(jin)入內至外筒(tong)體,在機(ji)(ji)體Z形往復(fu)折流(liu)后,充分利用(yong)熱(re)能烘干物料(liao)后再卸出。
烘干機筒(tong)體(ti)部分由三個同軸水平放置的內(nei)、中、外筒(tong)套疊(die)組成,這就使(shi)筒(tong)體(ti)的截面(mian)得到(dao)充分的利(li)用。其筒(tong)體(ti)外形總長度約為與(yu)之(zhi)相當的單(dan)筒(tong)的30-35%。從而大幅度地減少占地面(mian)積和廠(chang)房建筑面(mian)積。
該(gai)機的支承(cheng)(cheng)裝置,是在外筒(tong)上輪(lun)帶與托輪(lun)支承(cheng)(cheng),由(you)電(dian)機直接帶動托輪(lun)。通過托輪(lun)與輪(lun)帶摩擦,使筒(tong)體轉動。該(gai)機總體結構緊湊(cou)、合理、簡單,為便于(yu)磨損件的檢修更換(huan),在中(zhong)間設計成(cheng)軸(zhou)向剖(pou)分式,用(yong)螺栓(shuan)固定連接。
工作原理
物(wu)(wu)(wu)料(liao)由供料(liao)裝(zhuang)置進(jin)(jin)(jin)(jin)入回轉滾(gun)(gun)(gun)筒(tong)的內層(ceng)(ceng)(ceng)(ceng),實現順流烘(hong)(hong)干(gan),物(wu)(wu)(wu)料(liao)在(zai)內層(ceng)(ceng)(ceng)(ceng)的抄板下不斷(duan)抄起、散(san)(san)落呈螺(luo)旋行(xing)進(jin)(jin)(jin)(jin)式實現熱(re)交換,物(wu)(wu)(wu)料(liao)移(yi)動至內層(ceng)(ceng)(ceng)(ceng)的另(ling)一(yi)端進(jin)(jin)(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)行(xing)逆流烘(hong)(hong)干(gan),物(wu)(wu)(wu)料(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不斷(duan)地(di)被反復揚進(jin)(jin)(jin)(jin),呈進(jin)(jin)(jin)(jin)兩(liang)步退一(yi)步的行(xing)進(jin)(jin)(jin)(jin)方式,物(wu)(wu)(wu)料(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既充(chong)分吸收內層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)散(san)(san)發的熱(re)量,又吸收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)的熱(re)量,同時(shi)又延(yan)長(chang)了干(gan)燥(zao)(zao)時(shi)間,物(wu)(wu)(wu)料(liao)在(zai)此達到(dao)(dao)干(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)行(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一(yi)端而(er)落入外層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)料(liao)在(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)內呈矩形多回路方式行(xing)進(jin)(jin)(jin)(jin),達到(dao)(dao)干(gan)燥(zao)(zao)效(xiao)果的物(wu)(wu)(wu)料(liao)在(zai)熱(re)風作用(yong)下快(kuai)(kuai)速行(xing)進(jin)(jin)(jin)(jin)排出滾(gun)(gun)(gun)筒(tong),沒有(you)達到(dao)(dao)干(gan)燥(zao)(zao)效(xiao)果的濕(shi)物(wu)(wu)(wu)料(liao)因自(zi)重(zhong)而(er)不能快(kuai)(kuai)速行(xing)進(jin)(jin)(jin)(jin),物(wu)(wu)(wu)料(liao)在(zai)此矩形抄板內進(jin)(jin)(jin)(jin)行(xing)充(chong)分干(gan)燥(zao)(zao),由此完成干(gan)燥(zao)(zao)目的。
