產品概(gai)況(kuang)
回轉式(shi)三(san)筒(tong)烘(hong)(hong)(hong)干(gan)機改進(jin)原(yuan)單(dan)(dan)筒(tong)烘(hong)(hong)(hong)干(gan)機內部(bu)結(jie)構，增加入機前(qian)濕(shi)料的預烘(hong)(hong)(hong)干(gan)和延長濕(shi)料在機內烘(hong)(hong)(hong)干(gan)時間(jian)，再(zai)加上密(mi)封(feng)、保溫(wen)以(yi)及(ji)合理(li)的配套措施，使(shi)烘(hong)(hong)(hong)干(gan)機生(sheng)產能力與原(yuan)單(dan)(dan)筒(tong)式(shi)烘(hong)(hong)(hong)干(gan)機相比，提高(gao)48-80%，單(dan)(dan)位容積蒸發強度可(ke)達120-180kg/m3，標準煤(mei)耗僅為6-8kg/t。其技術先(xian)進(jin)、運行(xing)參數(shu)合理(li)，操(cao)作簡單(dan)(dan)可(ke)行(xing)，廣泛應用于各個行(xing)業的礦渣、粘土(tu)、煤(mei)。
產品結構
三(san)筒(tong)烘(hong)干(gan)(gan)機是通過對單筒(tong)烘(hong)干(gan)(gan)機的(de)單筒(tong)體改為套疊在一起(qi)的(de)三(san)筒(tong)，以(yi)縮短烘(hong)干(gan)(gan)機體的(de)外形(xing)尺寸。該機工作時，物(wu)(wu)料(liao)和熱(re)氣流(liu)依次進入內(nei)至外筒(tong)體，在機體Z形(xing)往復折(zhe)流(liu)后(hou)，充分利用熱(re)能烘(hong)干(gan)(gan)物(wu)(wu)料(liao)后(hou)再卸出。
烘干機(ji)筒(tong)體(ti)部分(fen)由三(san)個同軸水平放置的內(nei)、中、外筒(tong)套疊(die)組成，這就使(shi)筒(tong)體(ti)的截(jie)面(mian)得到充分(fen)的利用。其筒(tong)體(ti)外形總長度(du)約為與之相當的單筒(tong)的30-35%。從而大幅度(du)地(di)減少占(zhan)地(di)面(mian)積和(he)廠(chang)房建筑面(mian)積。
該(gai)機的支(zhi)承裝(zhuang)置，是在外筒上輪(lun)帶(dai)(dai)與(yu)托(tuo)輪(lun)支(zhi)承，由電(dian)機直接帶(dai)(dai)動(dong)托(tuo)輪(lun)。通過托(tuo)輪(lun)與(yu)輪(lun)帶(dai)(dai)摩擦，使筒體(ti)轉動(dong)。該(gai)機總體(ti)結構緊湊、合(he)理、簡(jian)單，為便于磨(mo)損件的檢修(xiu)更(geng)換，在中間設計成軸向剖分式(shi)，用(yong)螺(luo)栓固定連接。
工作原理(li)
物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)由(you)供料(liao)裝(zhuang)置進(jin)(jin)入回(hui)轉滾筒(tong)的(de)內(nei)層(ceng)(ceng)(ceng),實(shi)現(xian)順(shun)流烘干(gan)(gan),物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)的(de)抄(chao)(chao)板(ban)下(xia)不斷(duan)抄(chao)(chao)起、散落呈螺旋(xuan)行(xing)(xing)(xing)(xing)進(jin)(jin)式(shi)實(shi)現(xian)熱交換，物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)移動至(zhi)內(nei)層(ceng)(ceng)(ceng)的(de)另(ling)一(yi)端進(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)(xing)(xing)(xing)逆流烘干(gan)(gan)，物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不斷(duan)地被反復揚進(jin)(jin)，呈進(jin)(jin)兩步退一(yi)步的(de)行(xing)(xing)(xing)(xing)進(jin)(jin)方(fang)式(shi)，物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充(chong)分吸收內(nei)層(ceng)(ceng)(ceng)滾筒(tong)散發(fa)的(de)熱量(liang)，又(you)吸收中(zhong)(zhong)層(ceng)(ceng)(ceng)滾筒(tong)的(de)熱量(liang)，同時又(you)延長了干(gan)(gan)燥(zao)時間(jian)，物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)此(ci)(ci)達(da)到(dao)(dao)(dao)干(gan)(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)行(xing)(xing)(xing)(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)(ceng)另(ling)一(yi)端而落入外(wai)層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)外(wai)層(ceng)(ceng)(ceng)滾筒(tong)內(nei)呈矩形(xing)多回(hui)路(lu)方(fang)式(shi)行(xing)(xing)(xing)(xing)進(jin)(jin)，達(da)到(dao)(dao)(dao)干(gan)(gan)燥(zao)效(xiao)果的(de)物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)熱風作用下(xia)快速行(xing)(xing)(xing)(xing)進(jin)(jin)排(pai)出滾筒(tong)，沒有達(da)到(dao)(dao)(dao)干(gan)(gan)燥(zao)效(xiao)果的(de)濕(shi)物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)因自重而不能快速行(xing)(xing)(xing)(xing)進(jin)(jin)，物(wu)(wu)(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)此(ci)(ci)矩形(xing)抄(chao)(chao)板(ban)內(nei)進(jin)(jin)行(xing)(xing)(xing)(xing)充(chong)分干(gan)(gan)燥(zao)，由(you)此(ci)(ci)完成干(gan)(gan)燥(zao)目的(de)。
