產品概況(kuang)
回(hui)轉式三筒(tong)(tong)烘(hong)干(gan)(gan)(gan)機改進(jin)原單(dan)筒(tong)(tong)烘(hong)干(gan)(gan)(gan)機內(nei)部結(jie)構,增加入機前濕(shi)料的(de)(de)預烘(hong)干(gan)(gan)(gan)和延長濕(shi)料在機內(nei)烘(hong)干(gan)(gan)(gan)時間(jian),再加上密封、保溫以及合(he)理的(de)(de)配套措施,使(shi)烘(hong)干(gan)(gan)(gan)機生(sheng)產能(neng)力與(yu)原單(dan)筒(tong)(tong)式烘(hong)干(gan)(gan)(gan)機相比(bi),提高(gao)48-80%,單(dan)位容積蒸發強度可達120-180kg/m3,標準煤耗僅為6-8kg/t。其(qi)技(ji)術先進(jin)、運行(xing)參(can)數(shu)合(he)理,操(cao)作簡單(dan)可行(xing),廣泛應用(yong)于各個行(xing)業的(de)(de)礦渣、粘土(tu)、煤。
產品結構(gou)
三(san)筒(tong)烘干(gan)機是(shi)通過對(dui)單筒(tong)烘干(gan)機的(de)單筒(tong)體(ti)改為套疊在一起的(de)三(san)筒(tong),以縮短烘干(gan)機體(ti)的(de)外形尺寸。該(gai)機工作時(shi),物(wu)料和(he)熱(re)氣流依(yi)次(ci)進入(ru)內(nei)至(zhi)外筒(tong)體(ti),在機體(ti)Z形往復折流后(hou),充分(fen)利用熱(re)能烘干(gan)物(wu)料后(hou)再卸(xie)出。
烘干機(ji)筒(tong)(tong)體部分(fen)(fen)由三個同(tong)軸(zhou)水平放置的(de)(de)內、中(zhong)、外(wai)筒(tong)(tong)套疊組成(cheng),這就使筒(tong)(tong)體的(de)(de)截面得到充分(fen)(fen)的(de)(de)利用(yong)。其(qi)筒(tong)(tong)體外(wai)形(xing)總長(chang)度約(yue)為(wei)與之相當的(de)(de)單(dan)筒(tong)(tong)的(de)(de)30-35%。從而大幅度地減少(shao)占(zhan)地面積和廠(chang)房建筑(zhu)面積。
該(gai)機的支(zhi)(zhi)承裝置,是在外(wai)筒上輪(lun)帶與(yu)托(tuo)輪(lun)支(zhi)(zhi)承,由電(dian)機直接(jie)帶動托(tuo)輪(lun)。通過托(tuo)輪(lun)與(yu)輪(lun)帶摩(mo)擦,使(shi)筒體(ti)(ti)轉動。該(gai)機總體(ti)(ti)結構緊湊、合理(li)、簡單,為(wei)便于磨損件的檢修更換(huan),在中(zhong)間(jian)設計成軸向剖分式,用(yong)螺栓固定(ding)連接(jie)。
工作原理
物(wu)(wu)料(liao)(liao)由(you)(you)供料(liao)(liao)裝置進入(ru)(ru)回轉滾(gun)筒的(de)內(nei)層(ceng)(ceng),實現(xian)順流烘干(gan)(gan),物(wu)(wu)料(liao)(liao)在內(nei)層(ceng)(ceng)的(de)抄(chao)板下不(bu)斷(duan)抄(chao)起、散落(luo)呈(cheng)(cheng)螺旋行(xing)(xing)進式(shi)實現(xian)熱(re)交換,物(wu)(wu)料(liao)(liao)移動至內(nei)層(ceng)(ceng)的(de)另一(yi)端(duan)進入(ru)(ru)中(zhong)(zhong)層(ceng)(ceng),進行(xing)(xing)逆流烘干(gan)(gan),物(wu)(wu)料(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)不(bu)斷(duan)地被反復揚進,呈(cheng)(cheng)進兩步(bu)退一(yi)步(bu)的(de)行(xing)(xing)進方式(shi),物(wu)(wu)料(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)既充(chong)(chong)分(fen)吸收內(nei)層(ceng)(ceng)滾(gun)筒散發的(de)熱(re)量(liang),又吸收中(zhong)(zhong)層(ceng)(ceng)滾(gun)筒的(de)熱(re)量(liang),同時又延(yan)長了干(gan)(gan)燥(zao)時間,物(wu)(wu)料(liao)(liao)在此達到干(gan)(gan)燥(zao)狀態。物(wu)(wu)料(liao)(liao)行(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)另一(yi)端(duan)而落(luo)入(ru)(ru)外層(ceng)(ceng),物(wu)(wu)料(liao)(liao)在外層(ceng)(ceng)滾(gun)筒內(nei)呈(cheng)(cheng)矩形(xing)多(duo)回路方式(shi)行(xing)(xing)進,達到干(gan)(gan)燥(zao)效果(guo)的(de)物(wu)(wu)料(liao)(liao)在熱(re)風(feng)作用下快速行(xing)(xing)進排(pai)出滾(gun)筒,沒有達到干(gan)(gan)燥(zao)效果(guo)的(de)濕(shi)物(wu)(wu)料(liao)(liao)因自(zi)重而不(bu)能快速行(xing)(xing)進,物(wu)(wu)料(liao)(liao)在此矩形(xing)抄(chao)板內(nei)進行(xing)(xing)充(chong)(chong)分(fen)干(gan)(gan)燥(zao),由(you)(you)此完成干(gan)(gan)燥(zao)目(mu)的(de)。
