產品(pin)概況
回轉式三(san)筒烘(hong)(hong)(hong)干(gan)機改進(jin)原單筒烘(hong)(hong)(hong)干(gan)機內部結構,增加(jia)入(ru)機前濕料的(de)預(yu)烘(hong)(hong)(hong)干(gan)和延(yan)長濕料在機內烘(hong)(hong)(hong)干(gan)時間,再加(jia)上密封(feng)、保溫以及(ji)合理的(de)配套措施(shi),使烘(hong)(hong)(hong)干(gan)機生產能力與原單筒式烘(hong)(hong)(hong)干(gan)機相(xiang)比,提高48-80%,單位容(rong)積蒸發強度可達120-180kg/m3,標(biao)準煤耗(hao)僅為6-8kg/t。其(qi)技術先(xian)進(jin)、運行(xing)參數合理,操作簡單可行(xing),廣泛(fan)應(ying)用于各個(ge)行(xing)業(ye)的(de)礦渣、粘(zhan)土、煤。
產品結(jie)構(gou)
三(san)筒(tong)烘(hong)干機(ji)是(shi)通過(guo)對單(dan)筒(tong)烘(hong)干機(ji)的(de)單(dan)筒(tong)體(ti)(ti)改為套疊在一起的(de)三(san)筒(tong),以縮短烘(hong)干機(ji)體(ti)(ti)的(de)外(wai)(wai)形尺寸(cun)。該(gai)機(ji)工作時,物(wu)料(liao)和(he)熱氣流依次進入內(nei)至外(wai)(wai)筒(tong)體(ti)(ti),在機(ji)體(ti)(ti)Z形往復折流后(hou),充分利用(yong)熱能烘(hong)干物(wu)料(liao)后(hou)再卸出。
烘干機筒(tong)(tong)(tong)體(ti)部分由三個同(tong)軸水平放置的內、中、外(wai)筒(tong)(tong)(tong)套疊組成(cheng),這(zhe)就使(shi)筒(tong)(tong)(tong)體(ti)的截面得(de)到充分的利用。其筒(tong)(tong)(tong)體(ti)外(wai)形總長度(du)約(yue)為與(yu)之相當的單筒(tong)(tong)(tong)的30-35%。從而大幅度(du)地減少占(zhan)地面積和廠房建筑(zhu)面積。
該機的支承(cheng)裝置,是(shi)在外(wai)筒上輪(lun)帶(dai)與托(tuo)輪(lun)支承(cheng),由電(dian)機直(zhi)接帶(dai)動托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶(dai)摩擦,使筒體轉(zhuan)動。該機總體結構緊湊、合(he)理、簡(jian)單,為(wei)便于(yu)磨損件(jian)的檢(jian)修更(geng)換(huan),在中間設計成軸向剖分式,用螺栓固定連接。
工作原理(li)
物(wu)(wu)(wu)料(liao)(liao)由(you)(you)供料(liao)(liao)裝置進(jin)(jin)(jin)入回轉滾(gun)(gun)筒的內(nei)層(ceng),實(shi)現順流(liu)烘干(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)層(ceng)的抄板下不斷(duan)抄起、散(san)(san)落呈螺旋行(xing)(xing)(xing)(xing)進(jin)(jin)(jin)式(shi)實(shi)現熱(re)(re)交換,物(wu)(wu)(wu)料(liao)(liao)移(yi)動(dong)至內(nei)層(ceng)的另一端(duan)進(jin)(jin)(jin)入中(zhong)(zhong)層(ceng),進(jin)(jin)(jin)行(xing)(xing)(xing)(xing)逆流(liu)烘干(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)不斷(duan)地被反復揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩步退一步的行(xing)(xing)(xing)(xing)進(jin)(jin)(jin)方式(shi),物(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)既充分吸收(shou)內(nei)層(ceng)滾(gun)(gun)筒散(san)(san)發的熱(re)(re)量,又(you)吸收(shou)中(zhong)(zhong)層(ceng)滾(gun)(gun)筒的熱(re)(re)量,同時又(you)延長了(le)干(gan)燥時間,物(wu)(wu)(wu)料(liao)(liao)在(zai)此達到干(gan)燥狀態。物(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)(xing)(xing)至中(zhong)(zhong)層(ceng)另一端(duan)而落入外(wai)層(ceng),物(wu)(wu)(wu)料(liao)(liao)在(zai)外(wai)層(ceng)滾(gun)(gun)筒內(nei)呈矩(ju)形(xing)多回路方式(shi)行(xing)(xing)(xing)(xing)進(jin)(jin)(jin),達到干(gan)燥效(xiao)果的物(wu)(wu)(wu)料(liao)(liao)在(zai)熱(re)(re)風(feng)作(zuo)用下快速行(xing)(xing)(xing)(xing)進(jin)(jin)(jin)排出滾(gun)(gun)筒,沒有達到干(gan)燥效(xiao)果的濕物(wu)(wu)(wu)料(liao)(liao)因自重(zhong)而不能(neng)快速行(xing)(xing)(xing)(xing)進(jin)(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)在(zai)此矩(ju)形(xing)抄板內(nei)進(jin)(jin)(jin)行(xing)(xing)(xing)(xing)充分干(gan)燥,由(you)(you)此完成干(gan)燥目的。
