產品概(gai)況
回轉式(shi)三筒(tong)烘(hong)干機(ji)改進(jin)原單(dan)筒(tong)烘(hong)干機(ji)內部結(jie)構，增加(jia)入(ru)機(ji)前濕(shi)(shi)料的(de)預(yu)烘(hong)干和延長(chang)濕(shi)(shi)料在機(ji)內烘(hong)干時(shi)間，再加(jia)上密封、保溫(wen)以及合(he)理的(de)配(pei)套措施(shi)，使烘(hong)干機(ji)生產(chan)能力與原單(dan)筒(tong)式(shi)烘(hong)干機(ji)相比，提高(gao)48-80%，單(dan)位容積(ji)蒸(zheng)發強度可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術(shu)先進(jin)、運行參數(shu)合(he)理，操(cao)作簡單(dan)可行，廣泛應用(yong)于各個行業的(de)礦(kuang)渣(zha)、粘土、煤。
產品結構
三(san)筒(tong)(tong)烘(hong)(hong)(hong)干(gan)(gan)(gan)機(ji)(ji)是(shi)通過(guo)對單筒(tong)(tong)烘(hong)(hong)(hong)干(gan)(gan)(gan)機(ji)(ji)的單筒(tong)(tong)體(ti)改(gai)為套疊在一(yi)起的三(san)筒(tong)(tong)，以縮短烘(hong)(hong)(hong)干(gan)(gan)(gan)機(ji)(ji)體(ti)的外形尺寸。該機(ji)(ji)工作時(shi)，物(wu)料和熱氣流(liu)依次進入內至外筒(tong)(tong)體(ti)，在機(ji)(ji)體(ti)Z形往復折流(liu)后(hou)，充(chong)分利(li)用熱能烘(hong)(hong)(hong)干(gan)(gan)(gan)物(wu)料后(hou)再卸出。
烘干機筒(tong)體(ti)部分由(you)三(san)個同軸(zhou)水平(ping)放置的(de)內、中、外筒(tong)套疊(die)組成，這就使筒(tong)體(ti)的(de)截面得到(dao)充分的(de)利用。其筒(tong)體(ti)外形總長度(du)約(yue)為與之(zhi)相當的(de)單筒(tong)的(de)30-35%。從而大幅度(du)地減少占地面積和廠房建(jian)筑面積。
該機的支(zhi)承(cheng)(cheng)裝(zhuang)置，是在(zai)外筒(tong)上輪(lun)帶與(yu)托(tuo)輪(lun)支(zhi)承(cheng)(cheng)，由電機直接帶動托(tuo)輪(lun)。通過托(tuo)輪(lun)與(yu)輪(lun)帶摩擦，使筒(tong)體(ti)轉動。該機總(zong)體(ti)結(jie)構緊湊、合(he)理、簡單，為便于磨損件的檢修更換，在(zai)中間設計(ji)成軸向(xiang)剖(pou)分(fen)式，用螺栓固定(ding)連接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝置進(jin)(jin)(jin)(jin)入(ru)回(hui)轉滾筒(tong)的(de)(de)內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng),實現(xian)順(shun)流烘(hong)干(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)抄板下不斷(duan)抄起、散(san)落呈(cheng)(cheng)螺旋行進(jin)(jin)(jin)(jin)式實現(xian)熱交換，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移動至內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)另(ling)一端(duan)進(jin)(jin)(jin)(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)(jin)(jin)行逆流烘(hong)干(gan)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)不斷(duan)地被反復揚進(jin)(jin)(jin)(jin)，呈(cheng)(cheng)進(jin)(jin)(jin)(jin)兩(liang)步退一步的(de)(de)行進(jin)(jin)(jin)(jin)方(fang)式，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)既充(chong)分吸(xi)收(shou)內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)散(san)發的(de)(de)熱量(liang)，又吸(xi)收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)的(de)(de)熱量(liang)，同時又延長了(le)干(gan)燥(zao)時間，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此達到(dao)干(gan)燥(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行至中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)另(ling)一端(duan)而落入(ru)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)內呈(cheng)(cheng)矩形(xing)多回(hui)路方(fang)式行進(jin)(jin)(jin)(jin)，達到(dao)干(gan)燥(zao)效(xiao)果(guo)的(de)(de)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)熱風作(zuo)用下快(kuai)速(su)行進(jin)(jin)(jin)(jin)排出滾筒(tong)，沒有達到(dao)干(gan)燥(zao)效(xiao)果(guo)的(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因自重而不能快(kuai)速(su)行進(jin)(jin)(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此矩形(xing)抄板內進(jin)(jin)(jin)(jin)行充(chong)分干(gan)燥(zao)，由此完成(cheng)干(gan)燥(zao)目的(de)(de)。
