產品概況(kuang)
回(hui)轉式三筒烘(hong)(hong)(hong)干機(ji)改進(jin)原單(dan)筒烘(hong)(hong)(hong)干機(ji)內(nei)部結構，增(zeng)加入機(ji)前濕料(liao)的(de)預烘(hong)(hong)(hong)干和(he)延長濕料(liao)在機(ji)內(nei)烘(hong)(hong)(hong)干時間，再(zai)加上密(mi)封(feng)、保溫以及合理(li)的(de)配套措施，使烘(hong)(hong)(hong)干機(ji)生產能力與原單(dan)筒式烘(hong)(hong)(hong)干機(ji)相比，提高48-80%，單(dan)位容積蒸發(fa)強度可(ke)(ke)達120-180kg/m3，標準煤耗僅為(wei)6-8kg/t。其技術(shu)先進(jin)、運行參數合理(li)，操作(zuo)簡單(dan)可(ke)(ke)行，廣泛(fan)應(ying)用(yong)于各個行業的(de)礦渣、粘土、煤。
產品結構
三筒(tong)(tong)(tong)(tong)烘干(gan)機是通過對單筒(tong)(tong)(tong)(tong)烘干(gan)機的(de)單筒(tong)(tong)(tong)(tong)體改為套疊(die)在(zai)一起(qi)的(de)三筒(tong)(tong)(tong)(tong)，以(yi)縮短(duan)烘干(gan)機體的(de)外(wai)形(xing)尺寸。該(gai)機工作時，物料(liao)和熱氣流依次(ci)進入內至(zhi)外(wai)筒(tong)(tong)(tong)(tong)體，在(zai)機體Z形(xing)往(wang)復折流后，充分利用熱能烘干(gan)物料(liao)后再卸出(chu)。
烘干機筒體(ti)(ti)部(bu)分(fen)由三個(ge)同軸(zhou)水平(ping)放置的內、中(zhong)、外(wai)筒套疊(die)組成，這就(jiu)使筒體(ti)(ti)的截面得到充分(fen)的利(li)用。其筒體(ti)(ti)外(wai)形總長度(du)約為與之相(xiang)當的單筒的30-35%。從而大幅度(du)地減(jian)少占地面積(ji)和廠房建(jian)筑(zhu)面積(ji)。
該機的支承裝置(zhi)，是在(zai)外筒上輪(lun)帶與托(tuo)輪(lun)支承，由(you)電機直接帶動(dong)托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶摩(mo)擦，使筒體(ti)轉動(dong)。該機總體(ti)結構緊湊、合理、簡單，為便于磨損件的檢修(xiu)更換(huan)，在(zai)中間設(she)計成軸向(xiang)剖(pou)分式，用螺栓固定連接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝(zhuang)置進(jin)入(ru)回轉滾(gun)筒(tong)(tong)的內(nei)(nei)層(ceng)(ceng),實現(xian)(xian)順流烘干(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)內(nei)(nei)層(ceng)(ceng)的抄板(ban)(ban)下不斷抄起、散落(luo)呈(cheng)螺(luo)旋行(xing)(xing)(xing)進(jin)式(shi)實現(xian)(xian)熱(re)交換，物(wu)(wu)(wu)料(liao)(liao)移動至(zhi)內(nei)(nei)層(ceng)(ceng)的另一(yi)(yi)端進(jin)入(ru)中(zhong)層(ceng)(ceng)，進(jin)行(xing)(xing)(xing)逆流烘干(gan)，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)不斷地被(bei)反復揚(yang)進(jin)，呈(cheng)進(jin)兩步退一(yi)(yi)步的行(xing)(xing)(xing)進(jin)方式(shi)，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)既充分吸收(shou)內(nei)(nei)層(ceng)(ceng)滾(gun)筒(tong)(tong)散發的熱(re)量，又吸收(shou)中(zhong)層(ceng)(ceng)滾(gun)筒(tong)(tong)的熱(re)量，同時又延長了干(gan)燥(zao)時間，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)達(da)到(dao)干(gan)燥(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)(xing)至(zhi)中(zhong)層(ceng)(ceng)另一(yi)(yi)端而落(luo)入(ru)外層(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)外層(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)(nei)呈(cheng)矩形(xing)多回路方式(shi)行(xing)(xing)(xing)進(jin)，達(da)到(dao)干(gan)燥(zao)效(xiao)果的物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)熱(re)風作(zuo)用下快速行(xing)(xing)(xing)進(jin)排(pai)出滾(gun)筒(tong)(tong)，沒有達(da)到(dao)干(gan)燥(zao)效(xiao)果的濕(shi)物(wu)(wu)(wu)料(liao)(liao)因自重而不能(neng)快速行(xing)(xing)(xing)進(jin)，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)矩形(xing)抄板(ban)(ban)內(nei)(nei)進(jin)行(xing)(xing)(xing)充分干(gan)燥(zao)，由此(ci)完成(cheng)干(gan)燥(zao)目的。
