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。
產品(pin)結構
三(san)(san)筒(tong)式烘(hong)干(gan)機(ji)是通過對單筒(tong)烘(hong)干(gan)機(ji)的單筒(tong)體(ti)(ti)(ti)改為套疊在一起的三(san)(san)筒(tong)，以(yi)縮短烘(hong)干(gan)機(ji)體(ti)(ti)(ti)的外(wai)形尺(chi)寸。該機(ji)工作時(shi)，物(wu)料和熱氣流(liu)依次進入內(nei)至外(wai)筒(tong)體(ti)(ti)(ti)，在機(ji)體(ti)(ti)(ti)Z形往復折流(liu)后，充分利用熱能烘(hong)干(gan)物(wu)料后再卸出。
烘(hong)干機筒(tong)(tong)(tong)體部分由三個同軸水(shui)平(ping)放置(zhi)的內、中、外筒(tong)(tong)(tong)套疊組成，這就使筒(tong)(tong)(tong)體的截面得到充分的利用(yong)。其筒(tong)(tong)(tong)體外形總長度約(yue)為(wei)與(yu)之(zhi)相當的單筒(tong)(tong)(tong)的30-35%。從而大幅度地減少(shao)占地面積和(he)廠(chang)房建筑面積。
該(gai)機的(de)支(zhi)承裝置(zhi)，是(shi)在外(wai)筒(tong)上輪(lun)帶(dai)與托輪(lun)支(zhi)承，由電機直接帶(dai)動托輪(lun)。通過(guo)托輪(lun)與輪(lun)帶(dai)摩擦(ca)，使筒(tong)體(ti)轉動。該(gai)機總體(ti)結構緊湊(cou)、合理、簡單，為便于磨損(sun)件的(de)檢修更換，在中間設計(ji)成軸向剖分式，用螺栓固定連接。
工作(zuo)原理
物(wu)料(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)裝置(zhi)進(jin)(jin)入回轉滾(gun)筒的(de)(de)(de)內(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng),實現順流烘干,物(wu)料(liao)(liao)(liao)在內(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄板下(xia)不斷(duan)(duan)抄起(qi)、散(san)落呈螺(luo)旋行(xing)進(jin)(jin)式(shi)實現熱(re)交換，物(wu)料(liao)(liao)(liao)移(yi)動(dong)至內(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另一端(duan)進(jin)(jin)入中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)逆流烘干，物(wu)料(liao)(liao)(liao)在中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)不斷(duan)(duan)地(di)被(bei)反復揚進(jin)(jin)，呈進(jin)(jin)兩步退一步的(de)(de)(de)行(xing)進(jin)(jin)方式(shi)，物(wu)料(liao)(liao)(liao)在中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)既(ji)充(chong)分(fen)吸收內(nei)(nei)(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒散(san)發的(de)(de)(de)熱(re)量，又吸收中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒的(de)(de)(de)熱(re)量，同時(shi)又延長(chang)了干燥(zao)(zao)時(shi)間，物(wu)料(liao)(liao)(liao)在此(ci)達(da)到干燥(zao)(zao)狀態。物(wu)料(liao)(liao)(liao)行(xing)至中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)另一端(duan)而(er)落入外(wai)層(ceng)(ceng)(ceng)(ceng)，物(wu)料(liao)(liao)(liao)在外(wai)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒內(nei)(nei)(nei)呈矩形多回路(lu)方式(shi)行(xing)進(jin)(jin)，達(da)到干燥(zao)(zao)效(xiao)果的(de)(de)(de)物(wu)料(liao)(liao)(liao)在熱(re)風作用下(xia)快速行(xing)進(jin)(jin)排(pai)出滾(gun)筒，沒有達(da)到干燥(zao)(zao)效(xiao)果的(de)(de)(de)濕物(wu)料(liao)(liao)(liao)因自重而(er)不能快速行(xing)進(jin)(jin)，物(wu)料(liao)(liao)(liao)在此(ci)矩形抄板內(nei)(nei)(nei)進(jin)(jin)行(xing)充(chong)分(fen)干燥(zao)(zao)，由(you)此(ci)完(wan)成干燥(zao)(zao)目(mu)的(de)(de)(de)。
