產品(pin)概況
回轉式三(san)筒烘(hong)干(gan)(gan)機(ji)改進原單(dan)筒烘(hong)干(gan)(gan)機(ji)內部結(jie)構,增加入機(ji)前濕(shi)料(liao)的預(yu)烘(hong)干(gan)(gan)和(he)延長濕(shi)料(liao)在機(ji)內烘(hong)干(gan)(gan)時(shi)間,再(zai)加上密封、保(bao)溫以及合(he)(he)理的配套措施,使(shi)烘(hong)干(gan)(gan)機(ji)生產能力(li)與原單(dan)筒式烘(hong)干(gan)(gan)機(ji)相(xiang)比,提高48-80%,單(dan)位(wei)容積蒸發強度可達120-180kg/m3,標準煤(mei)耗(hao)僅為6-8kg/t。其技術(shu)先進、運行(xing)(xing)參數(shu)合(he)(he)理,操作簡單(dan)可行(xing)(xing),廣泛應用(yong)于各個行(xing)(xing)業的礦渣、粘土、煤(mei)。
產品結構(gou)
三筒(tong)烘干(gan)(gan)機(ji)是通過對單筒(tong)烘干(gan)(gan)機(ji)的(de)單筒(tong)體(ti)改(gai)為套疊(die)在(zai)一起的(de)三筒(tong),以縮短烘干(gan)(gan)機(ji)體(ti)的(de)外形尺寸。該(gai)機(ji)工作時,物料(liao)和熱氣流依次進入(ru)內至外筒(tong)體(ti),在(zai)機(ji)體(ti)Z形往復折流后,充分利(li)用(yong)熱能烘干(gan)(gan)物料(liao)后再(zai)卸出。
烘干機(ji)筒(tong)(tong)(tong)(tong)體部分(fen)由三個同軸水平放(fang)置的(de)內(nei)、中、外筒(tong)(tong)(tong)(tong)套(tao)疊(die)組成,這就使筒(tong)(tong)(tong)(tong)體的(de)截面得到充分(fen)的(de)利用(yong)。其筒(tong)(tong)(tong)(tong)體外形總長度約為與(yu)之相當的(de)單(dan)筒(tong)(tong)(tong)(tong)的(de)30-35%。從(cong)而大幅度地(di)減少占地(di)面積和廠房建筑面積。
該(gai)機(ji)的支承(cheng)裝置,是在外(wai)筒(tong)上輪(lun)帶與托輪(lun)支承(cheng),由(you)電機(ji)直接帶動托輪(lun)。通(tong)過托輪(lun)與輪(lun)帶摩(mo)擦,使(shi)筒(tong)體轉動。該(gai)機(ji)總(zong)體結構緊湊、合理(li)、簡單,為(wei)便(bian)于磨損件的檢修更換,在中間設(she)計成軸向剖分式(shi),用螺栓(shuan)固定連(lian)接。
工作原理
物(wu)料由供料裝置進(jin)(jin)入(ru)回(hui)轉滾筒(tong)(tong)的(de)(de)(de)內(nei)層(ceng)(ceng)(ceng),實現順流(liu)烘(hong)干(gan)(gan),物(wu)料在(zai)內(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)板(ban)下(xia)不(bu)斷(duan)抄(chao)起、散(san)落(luo)呈螺旋行(xing)(xing)進(jin)(jin)式實現熱(re)交換,物(wu)料移動至(zhi)內(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)另一(yi)(yi)端(duan)進(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)行(xing)(xing)逆流(liu)烘(hong)干(gan)(gan),物(wu)料在(zai)中(zhong)層(ceng)(ceng)(ceng)不(bu)斷(duan)地被反復揚進(jin)(jin),呈進(jin)(jin)兩步退一(yi)(yi)步的(de)(de)(de)行(xing)(xing)進(jin)(jin)方式,物(wu)料在(zai)中(zhong)層(ceng)(ceng)(ceng)既充分吸(xi)收內(nei)層(ceng)(ceng)(ceng)滾筒(tong)(tong)散(san)發的(de)(de)(de)熱(re)量(liang),又(you)吸(xi)收中(zhong)層(ceng)(ceng)(ceng)滾筒(tong)(tong)的(de)(de)(de)熱(re)量(liang),同時又(you)延長了干(gan)(gan)燥(zao)時間,物(wu)料在(zai)此達(da)(da)到(dao)干(gan)(gan)燥(zao)狀態(tai)。物(wu)料行(xing)(xing)至(zhi)中(zhong)層(ceng)(ceng)(ceng)另一(yi)(yi)端(duan)而(er)落(luo)入(ru)外(wai)層(ceng)(ceng)(ceng),物(wu)料在(zai)外(wai)層(ceng)(ceng)(ceng)滾筒(tong)(tong)內(nei)呈矩(ju)形多回(hui)路方式行(xing)(xing)進(jin)(jin),達(da)(da)到(dao)干(gan)(gan)燥(zao)效果(guo)的(de)(de)(de)物(wu)料在(zai)熱(re)風作用下(xia)快速行(xing)(xing)進(jin)(jin)排出滾筒(tong)(tong),沒有達(da)(da)到(dao)干(gan)(gan)燥(zao)效果(guo)的(de)(de)(de)濕物(wu)料因自(zi)重而(er)不(bu)能快速行(xing)(xing)進(jin)(jin),物(wu)料在(zai)此矩(ju)形抄(chao)板(ban)內(nei)進(jin)(jin)行(xing)(xing)充分干(gan)(gan)燥(zao),由此完(wan)成干(gan)(gan)燥(zao)目的(de)(de)(de)。
