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(jie)構
三筒(tong)式(shi)烘(hong)(hong)干(gan)機(ji)是通過(guo)對單筒(tong)烘(hong)(hong)干(gan)機(ji)的單筒(tong)體(ti)改為套疊在(zai)一(yi)起的三筒(tong)，以縮短(duan)烘(hong)(hong)干(gan)機(ji)體(ti)的外形(xing)尺寸。該機(ji)工作時(shi)，物料和熱(re)氣流依次進入內至(zhi)外筒(tong)體(ti)，在(zai)機(ji)體(ti)Z形(xing)往復(fu)折流后(hou)，充分(fen)利用熱(re)能烘(hong)(hong)干(gan)物料后(hou)再卸出。
烘干機(ji)筒(tong)體(ti)部分(fen)由三(san)個(ge)同軸(zhou)水(shui)平(ping)放置的內、中(zhong)、外筒(tong)套(tao)疊組成，這就(jiu)使筒(tong)體(ti)的截面得(de)到充分(fen)的利(li)用。其筒(tong)體(ti)外形總長(chang)度(du)約(yue)為與之相當的單(dan)筒(tong)的30-35%。從而大(da)幅度(du)地(di)減少占(zhan)地(di)面積和廠房(fang)建筑(zhu)面積。
該(gai)機的支承裝置(zhi)，是(shi)在外(wai)筒(tong)上輪(lun)(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)(lun)支承，由電機直接帶(dai)動(dong)托(tuo)輪(lun)(lun)(lun)。通(tong)過(guo)托(tuo)輪(lun)(lun)(lun)與輪(lun)(lun)(lun)帶(dai)摩擦，使(shi)筒(tong)體(ti)轉(zhuan)動(dong)。該(gai)機總體(ti)結(jie)構緊湊、合理、簡單(dan)，為便于(yu)磨損件(jian)的檢修(xiu)更換，在中間設計(ji)成軸(zhou)向剖分式，用螺栓(shuan)固定連接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置(zhi)進(jin)(jin)入回轉滾(gun)筒(tong)(tong)的內層(ceng)(ceng)(ceng)(ceng),實現順流烘干,物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)(ceng)的抄(chao)(chao)板(ban)下(xia)(xia)不(bu)斷(duan)抄(chao)(chao)起、散落(luo)呈螺旋(xuan)行(xing)(xing)進(jin)(jin)式實現熱交換，物(wu)(wu)(wu)料(liao)(liao)(liao)移動(dong)至內層(ceng)(ceng)(ceng)(ceng)的另(ling)一(yi)端進(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)(xing)逆流烘干，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷(duan)地被反(fan)復揚進(jin)(jin)，呈進(jin)(jin)兩步退一(yi)步的行(xing)(xing)進(jin)(jin)方式，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸(xi)收內層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)散發的熱量，又吸(xi)收中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)的熱量，同(tong)時又延長了(le)干燥(zao)時間，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)(ci)達到干燥(zao)狀(zhuang)態。物(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一(yi)端而(er)落(luo)入外層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)內呈矩形多(duo)回路(lu)方式行(xing)(xing)進(jin)(jin)，達到干燥(zao)效果的物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)熱風(feng)作用下(xia)(xia)快速行(xing)(xing)進(jin)(jin)排出滾(gun)筒(tong)(tong)，沒有達到干燥(zao)效果的濕物(wu)(wu)(wu)料(liao)(liao)(liao)因自重而(er)不(bu)能快速行(xing)(xing)進(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)(ci)矩形抄(chao)(chao)板(ban)內進(jin)(jin)行(xing)(xing)充分干燥(zao)，由此(ci)(ci)完成干燥(zao)目的。
