產品概況
回轉(zhuan)式(shi)三筒烘(hong)干(gan)機(ji)(ji)(ji)改進(jin)(jin)原單(dan)筒烘(hong)干(gan)機(ji)(ji)(ji)內部結(jie)構,增加入機(ji)(ji)(ji)前濕料(liao)的預烘(hong)干(gan)和(he)延長濕料(liao)在(zai)機(ji)(ji)(ji)內烘(hong)干(gan)時間,再(zai)加上密封、保溫以及合理(li)的配套措施,使(shi)烘(hong)干(gan)機(ji)(ji)(ji)生產能力與原單(dan)筒式(shi)烘(hong)干(gan)機(ji)(ji)(ji)相比,提高(gao)48-80%,單(dan)位容(rong)積蒸發強(qiang)度(du)可達(da)120-180kg/m3,標準煤(mei)耗(hao)僅為6-8kg/t。其技(ji)術先進(jin)(jin)、運行(xing)(xing)參數合理(li),操作簡(jian)單(dan)可行(xing)(xing),廣(guang)泛應用于各個行(xing)(xing)業的礦渣、粘土、煤(mei)。
產品(pin)結構
三筒(tong)(tong)(tong)(tong)烘(hong)干機是通過對單筒(tong)(tong)(tong)(tong)烘(hong)干機的(de)單筒(tong)(tong)(tong)(tong)體改為套疊在一起的(de)三筒(tong)(tong)(tong)(tong),以縮短(duan)烘(hong)干機體的(de)外形尺(chi)寸。該機工(gong)作時,物料(liao)和熱氣流(liu)依次進入內至外筒(tong)(tong)(tong)(tong)體,在機體Z形往復折(zhe)流(liu)后(hou),充分利用熱能烘(hong)干物料(liao)后(hou)再卸出。
烘干機筒體(ti)(ti)部分(fen)由三個同軸水平(ping)放置的(de)內、中、外筒套疊(die)組成,這就使筒體(ti)(ti)的(de)截面得到充分(fen)的(de)利(li)用。其筒體(ti)(ti)外形總長(chang)度約為與之相當(dang)的(de)單筒的(de)30-35%。從而大(da)幅度地減少占地面積(ji)和廠(chang)房建筑(zhu)面積(ji)。
該機的支承裝置,是在外(wai)筒(tong)(tong)上輪(lun)帶與托輪(lun)支承,由電機直接帶動托輪(lun)。通過(guo)托輪(lun)與輪(lun)帶摩擦,使(shi)筒(tong)(tong)體轉(zhuan)動。該機總(zong)體結構緊湊、合理、簡單,為便于磨損件的檢(jian)修更換(huan),在中間設計成軸向剖分式,用(yong)螺栓(shuan)固定連接。
工作原理(li)
物(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)(jin)入(ru)回轉滾(gun)筒(tong)的(de)(de)內(nei)層(ceng),實(shi)現(xian)順流(liu)烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)層(ceng)的(de)(de)抄板(ban)下不(bu)斷抄起(qi)、散(san)落呈螺(luo)旋行(xing)(xing)進(jin)(jin)(jin)(jin)式實(shi)現(xian)熱(re)交換,物(wu)(wu)(wu)(wu)料(liao)(liao)移動(dong)至內(nei)層(ceng)的(de)(de)另一端進(jin)(jin)(jin)(jin)入(ru)中(zhong)層(ceng),進(jin)(jin)(jin)(jin)行(xing)(xing)逆(ni)流(liu)烘干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)不(bu)斷地被反(fan)復(fu)揚進(jin)(jin)(jin)(jin),呈進(jin)(jin)(jin)(jin)兩步(bu)(bu)退一步(bu)(bu)的(de)(de)行(xing)(xing)進(jin)(jin)(jin)(jin)方(fang)式,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)既充分吸收內(nei)層(ceng)滾(gun)筒(tong)散(san)發的(de)(de)熱(re)量(liang),又(you)吸收中(zhong)層(ceng)滾(gun)筒(tong)的(de)(de)熱(re)量(liang),同時又(you)延(yan)長(chang)了干(gan)(gan)(gan)燥(zao)時間(jian),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)達(da)到干(gan)(gan)(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)至中(zhong)層(ceng)另一端而(er)落入(ru)外(wai)層(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)外(wai)層(ceng)滾(gun)筒(tong)內(nei)呈矩(ju)形(xing)多回路方(fang)式行(xing)(xing)進(jin)(jin)(jin)(jin),達(da)到干(gan)(gan)(gan)燥(zao)效(xiao)果(guo)的(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)熱(re)風作用下快(kuai)速行(xing)(xing)進(jin)(jin)(jin)(jin)排出滾(gun)筒(tong),沒有達(da)到干(gan)(gan)(gan)燥(zao)效(xiao)果(guo)的(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)因自重而(er)不(bu)能(neng)快(kuai)速行(xing)(xing)進(jin)(jin)(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)矩(ju)形(xing)抄板(ban)內(nei)進(jin)(jin)(jin)(jin)行(xing)(xing)充分干(gan)(gan)(gan)燥(zao),由此(ci)完成干(gan)(gan)(gan)燥(zao)目的(de)(de)。
