產品概況(kuang)
回轉式三筒(tong)烘干機(ji)改進(jin)原單(dan)筒(tong)烘干機(ji)內(nei)部結構，增加(jia)(jia)入機(ji)前濕料的(de)預(yu)烘干和(he)延(yan)長濕料在(zai)機(ji)內(nei)烘干時(shi)間，再加(jia)(jia)上密封、保溫(wen)以及合(he)(he)理的(de)配套措施，使烘干機(ji)生產能力與(yu)原單(dan)筒(tong)式烘干機(ji)相比(bi)，提高48-80%，單(dan)位容積蒸(zheng)發(fa)強度可達120-180kg/m3，標準煤(mei)耗僅(jin)為6-8kg/t。其技術先(xian)進(jin)、運行參數(shu)合(he)(he)理，操作(zuo)簡(jian)單(dan)可行，廣泛應用于各個行業的(de)礦渣、粘(zhan)土(tu)、煤(mei)。
產品(pin)結構(gou)
三筒(tong)(tong)烘(hong)干(gan)機(ji)(ji)是(shi)通過對單筒(tong)(tong)烘(hong)干(gan)機(ji)(ji)的(de)(de)單筒(tong)(tong)體改(gai)為(wei)套疊在一起的(de)(de)三筒(tong)(tong)，以縮短烘(hong)干(gan)機(ji)(ji)體的(de)(de)外形(xing)尺寸。該機(ji)(ji)工作時，物料和熱(re)氣流依次(ci)進入內(nei)至外筒(tong)(tong)體，在機(ji)(ji)體Z形(xing)往復折流后(hou)，充分利用熱(re)能烘(hong)干(gan)物料后(hou)再卸出(chu)。
烘干機筒(tong)(tong)體(ti)(ti)部(bu)分(fen)由三個同(tong)軸水(shui)平(ping)放置的內、中(zhong)、外筒(tong)(tong)套疊組成，這就使(shi)筒(tong)(tong)體(ti)(ti)的截面得到充分(fen)的利用。其筒(tong)(tong)體(ti)(ti)外形總長度(du)約為與之相(xiang)當的單(dan)筒(tong)(tong)的30-35%。從而大幅度(du)地減(jian)少占地面積和廠房(fang)建(jian)筑(zhu)面積。
該機(ji)(ji)的支承(cheng)裝置，是(shi)在(zai)外筒上輪(lun)帶(dai)與托輪(lun)支承(cheng)，由電機(ji)(ji)直接帶(dai)動(dong)(dong)托輪(lun)。通過托輪(lun)與輪(lun)帶(dai)摩擦，使筒體轉動(dong)(dong)。該機(ji)(ji)總體結構(gou)緊湊、合理、簡單，為便于(yu)磨損件(jian)的檢修更換，在(zai)中間設計成軸向剖分式，用螺栓固定(ding)連接。
工(gong)作原理
物(wu)(wu)(wu)料由供料裝置進(jin)(jin)入(ru)回轉滾(gun)(gun)筒的(de)(de)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng),實(shi)現順(shun)流(liu)(liu)烘干(gan)(gan),物(wu)(wu)(wu)料在(zai)(zai)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄(chao)板下(xia)不斷抄(chao)起、散(san)落呈螺旋行(xing)(xing)進(jin)(jin)式實(shi)現熱(re)交換(huan)，物(wu)(wu)(wu)料移動(dong)至內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)另(ling)一(yi)端進(jin)(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)(xing)逆流(liu)(liu)烘干(gan)(gan)，物(wu)(wu)(wu)料在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)不斷地被(bei)反復揚進(jin)(jin)，呈進(jin)(jin)兩步(bu)退一(yi)步(bu)的(de)(de)行(xing)(xing)進(jin)(jin)方式，物(wu)(wu)(wu)料在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)既充分(fen)(fen)吸收內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒散(san)發的(de)(de)熱(re)量，又吸收中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒的(de)(de)熱(re)量，同時又延長(chang)了干(gan)(gan)燥時間(jian)，物(wu)(wu)(wu)料在(zai)(zai)此達(da)到干(gan)(gan)燥狀態。物(wu)(wu)(wu)料行(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一(yi)端而(er)落入(ru)外層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒內(nei)(nei)呈矩形(xing)多(duo)回路方式行(xing)(xing)進(jin)(jin)，達(da)到干(gan)(gan)燥效果的(de)(de)物(wu)(wu)(wu)料在(zai)(zai)熱(re)風(feng)作用下(xia)快速行(xing)(xing)進(jin)(jin)排(pai)出(chu)滾(gun)(gun)筒，沒(mei)有達(da)到干(gan)(gan)燥效果的(de)(de)濕物(wu)(wu)(wu)料因自重而(er)不能快速行(xing)(xing)進(jin)(jin)，物(wu)(wu)(wu)料在(zai)(zai)此矩形(xing)抄(chao)板內(nei)(nei)進(jin)(jin)行(xing)(xing)充分(fen)(fen)干(gan)(gan)燥，由此完成干(gan)(gan)燥目的(de)(de)。
