產(chan)品概況
回轉式三筒(tong)烘(hong)干(gan)(gan)機(ji)改進(jin)原單(dan)筒(tong)烘(hong)干(gan)(gan)機(ji)內部結構,增加入機(ji)前濕(shi)料(liao)的預烘(hong)干(gan)(gan)和(he)延長濕(shi)料(liao)在機(ji)內烘(hong)干(gan)(gan)時間,再加上密封(feng)、保溫(wen)以及合(he)理的配套措施,使烘(hong)干(gan)(gan)機(ji)生(sheng)產能力與(yu)原單(dan)筒(tong)式烘(hong)干(gan)(gan)機(ji)相比,提高(gao)48-80%,單(dan)位容積蒸發強度可達(da)120-180kg/m3,標準煤(mei)耗僅為(wei)6-8kg/t。其技術先(xian)進(jin)、運行參數合(he)理,操(cao)作簡單(dan)可行,廣泛應用于各個行業的礦渣、粘(zhan)土、煤(mei)。
產品結(jie)構(gou)
三筒(tong)烘(hong)干機(ji)是通過(guo)對單(dan)筒(tong)烘(hong)干機(ji)的單(dan)筒(tong)體(ti)改為套疊在一起的三筒(tong),以縮(suo)短烘(hong)干機(ji)體(ti)的外形尺寸(cun)。該機(ji)工作時,物(wu)(wu)料(liao)和(he)熱(re)氣流依(yi)次進入內至外筒(tong)體(ti),在機(ji)體(ti)Z形往復折流后,充(chong)分(fen)利用(yong)熱(re)能烘(hong)干物(wu)(wu)料(liao)后再卸出。
烘干(gan)機筒體(ti)部(bu)分由三個同(tong)軸水(shui)平放置的(de)(de)(de)內、中、外(wai)筒套疊組成,這就使筒體(ti)的(de)(de)(de)截(jie)面(mian)得到充分的(de)(de)(de)利用。其筒體(ti)外(wai)形總(zong)長度(du)約為(wei)與之相當的(de)(de)(de)單筒的(de)(de)(de)30-35%。從而(er)大(da)幅度(du)地(di)減少(shao)占(zhan)地(di)面(mian)積和廠房建筑(zhu)面(mian)積。
該機(ji)的支承裝置,是在(zai)外(wai)筒上輪帶與托(tuo)輪支承,由電(dian)機(ji)直接(jie)帶動托(tuo)輪。通過托(tuo)輪與輪帶摩擦,使筒體(ti)轉動。該機(ji)總體(ti)結構(gou)緊湊、合理、簡(jian)單,為便(bian)于磨(mo)損件(jian)的檢修更換(huan),在(zai)中間(jian)設計成軸向剖分式,用(yong)螺(luo)栓固(gu)定連(lian)接(jie)。
工作原理
物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進入(ru)(ru)回(hui)轉滾(gun)筒的內(nei)層(ceng)(ceng),實(shi)現順流烘干(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)層(ceng)(ceng)的抄板(ban)下不(bu)斷抄起、散(san)落(luo)(luo)呈(cheng)螺(luo)旋行(xing)進式實(shi)現熱交換,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)移動至內(nei)層(ceng)(ceng)的另(ling)一端進入(ru)(ru)中(zhong)層(ceng)(ceng),進行(xing)逆(ni)流烘干(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)不(bu)斷地被(bei)反(fan)復(fu)揚進,呈(cheng)進兩步(bu)退(tui)一步(bu)的行(xing)進方式,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)既充分吸收(shou)內(nei)層(ceng)(ceng)滾(gun)筒散(san)發的熱量(liang),又(you)吸收(shou)中(zhong)層(ceng)(ceng)滾(gun)筒的熱量(liang),同時又(you)延(yan)長了干(gan)(gan)燥(zao)(zao)時間(jian),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此達到干(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)另(ling)一端而(er)落(luo)(luo)入(ru)(ru)外層(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)外層(ceng)(ceng)滾(gun)筒內(nei)呈(cheng)矩(ju)形多(duo)回(hui)路(lu)方式行(xing)進,達到干(gan)(gan)燥(zao)(zao)效(xiao)果的物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)熱風作用(yong)下快(kuai)速(su)行(xing)進排出(chu)滾(gun)筒,沒有達到干(gan)(gan)燥(zao)(zao)效(xiao)果的濕(shi)物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)因自重(zhong)而(er)不(bu)能快(kuai)速(su)行(xing)進,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此矩(ju)形抄板(ban)內(nei)進行(xing)充分干(gan)(gan)燥(zao)(zao),由此完成干(gan)(gan)燥(zao)(zao)目的。
