產品概況
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(chan)品(pin)結構
三筒(tong)(tong)式烘(hong)干(gan)機是通過對單筒(tong)(tong)烘(hong)干(gan)機的單筒(tong)(tong)體(ti)(ti)(ti)改為套疊在(zai)一起的三筒(tong)(tong)，以縮短(duan)烘(hong)干(gan)機體(ti)(ti)(ti)的外(wai)(wai)形尺寸(cun)。該機工作(zuo)時，物料和(he)熱(re)氣流(liu)依(yi)次(ci)進入(ru)內至外(wai)(wai)筒(tong)(tong)體(ti)(ti)(ti)，在(zai)機體(ti)(ti)(ti)Z形往復折流(liu)后，充分利用熱(re)能烘(hong)干(gan)物料后再(zai)卸出。
烘干機筒體(ti)部(bu)分由三個同軸水平放(fang)置的(de)(de)內、中、外(wai)筒套疊組成，這就使筒體(ti)的(de)(de)截面得到充(chong)分的(de)(de)利(li)用。其筒體(ti)外(wai)形總長度約為與之(zhi)相當的(de)(de)單筒的(de)(de)30-35%。從而(er)大幅度地減少占地面積(ji)和(he)廠房建(jian)筑面積(ji)。
該機(ji)的支承裝置(zhi)，是在(zai)外筒(tong)上輪(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)支承，由電機(ji)直接(jie)帶(dai)動托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶(dai)摩(mo)擦，使筒(tong)體轉動。該機(ji)總體結構緊湊(cou)、合理、簡(jian)單，為便于磨損件的檢修更換，在(zai)中間設計成軸向剖分式，用螺栓固定連接(jie)。
工作(zuo)原理
物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)由(you)供料(liao)(liao)裝置進(jin)(jin)入回轉滾(gun)(gun)筒(tong)(tong)的(de)(de)內層(ceng)(ceng)(ceng),實現(xian)(xian)順流(liu)烘干(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)內層(ceng)(ceng)(ceng)的(de)(de)抄(chao)板下不斷(duan)(duan)抄(chao)起、散落呈螺(luo)旋行(xing)進(jin)(jin)式(shi)(shi)實現(xian)(xian)熱交換，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)移動至內層(ceng)(ceng)(ceng)的(de)(de)另(ling)一端(duan)進(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)逆(ni)流(liu)烘干(gan)，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)不斷(duan)(duan)地(di)被反復揚進(jin)(jin)，呈進(jin)(jin)兩步退一步的(de)(de)行(xing)進(jin)(jin)方式(shi)(shi)，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)既充分吸(xi)收(shou)內層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)散發(fa)的(de)(de)熱量，又(you)吸(xi)收(shou)中(zhong)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)的(de)(de)熱量，同(tong)時(shi)又(you)延長(chang)了干(gan)燥(zao)(zao)時(shi)間，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此達到(dao)干(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)(ceng)另(ling)一端(duan)而落入外(wai)層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)內呈矩形多回路方式(shi)(shi)行(xing)進(jin)(jin)，達到(dao)干(gan)燥(zao)(zao)效果的(de)(de)物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)熱風作用下快速行(xing)進(jin)(jin)排(pai)出滾(gun)(gun)筒(tong)(tong)，沒有(you)達到(dao)干(gan)燥(zao)(zao)效果的(de)(de)濕(shi)物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)因(yin)自重而不能快速行(xing)進(jin)(jin)，物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此矩形抄(chao)板內進(jin)(jin)行(xing)充分干(gan)燥(zao)(zao)，由(you)此完成(cheng)干(gan)燥(zao)(zao)目的(de)(de)。
