產品(pin)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。
產品(pin)結構
三(san)筒式烘(hong)(hong)干機是通過對單筒烘(hong)(hong)干機的單筒體改為套疊在一起的三(san)筒,以縮短(duan)烘(hong)(hong)干機體的外形尺寸。該機工作時,物料和熱(re)氣流(liu)依次進入內(nei)至外筒體,在機體Z形往復折流(liu)后,充分利(li)用(yong)熱(re)能烘(hong)(hong)干物料后再卸出。
烘干機(ji)筒(tong)(tong)體(ti)部分由(you)三(san)個同軸(zhou)水平放置的(de)內、中、外筒(tong)(tong)套疊(die)組成,這就使(shi)筒(tong)(tong)體(ti)的(de)截(jie)面(mian)得到充分的(de)利用。其(qi)筒(tong)(tong)體(ti)外形總長(chang)度約為(wei)與(yu)之相當的(de)單筒(tong)(tong)的(de)30-35%。從而大幅(fu)度地(di)減少占地(di)面(mian)積(ji)和廠房建(jian)筑面(mian)積(ji)。
該(gai)(gai)機的支承裝置,是在外筒上輪帶與托輪支承,由電機直接帶動(dong)托輪。通過托輪與輪帶摩擦,使筒體轉動(dong)。該(gai)(gai)機總體結(jie)構緊湊、合理、簡單,為便于磨損(sun)件的檢(jian)修(xiu)更換(huan),在中間(jian)設計成(cheng)軸向剖分式,用螺栓固定(ding)連接。
工作原理
物(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置(zhi)進(jin)(jin)(jin)入回轉滾(gun)(gun)筒(tong)的(de)內(nei)層(ceng)(ceng)(ceng),實(shi)現順(shun)流烘(hong)干(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)的(de)抄板下不(bu)斷抄起、散落呈(cheng)螺旋行(xing)進(jin)(jin)(jin)式實(shi)現熱交換,物(wu)(wu)料(liao)(liao)(liao)移動(dong)至內(nei)層(ceng)(ceng)(ceng)的(de)另(ling)一端(duan)進(jin)(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)逆流烘(hong)干(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)不(bu)斷地被反復(fu)揚進(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)兩步退一步的(de)行(xing)進(jin)(jin)(jin)方式,物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)既(ji)充(chong)分吸收(shou)內(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散發的(de)熱量(liang),又(you)吸收(shou)中(zhong)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)熱量(liang),同時又(you)延長了干(gan)(gan)燥(zao)(zao)(zao)時間,物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)(ci)達到(dao)(dao)干(gan)(gan)燥(zao)(zao)(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)(ceng)另(ling)一端(duan)而落入外層(ceng)(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)呈(cheng)矩形多回路方式行(xing)進(jin)(jin)(jin),達到(dao)(dao)干(gan)(gan)燥(zao)(zao)(zao)效果(guo)的(de)物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)熱風(feng)作(zuo)用下快速(su)行(xing)進(jin)(jin)(jin)排(pai)出(chu)滾(gun)(gun)筒(tong),沒有(you)達到(dao)(dao)干(gan)(gan)燥(zao)(zao)(zao)效果(guo)的(de)濕物(wu)(wu)料(liao)(liao)(liao)因自重(zhong)而不(bu)能快速(su)行(xing)進(jin)(jin)(jin),物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)(ci)矩形抄板內(nei)進(jin)(jin)(jin)行(xing)充(chong)分干(gan)(gan)燥(zao)(zao)(zao),由此(ci)(ci)完成干(gan)(gan)燥(zao)(zao)(zao)目的(de)。
