產品(pin)概況
回轉式三筒烘干機改進原單筒烘干機內部結構,增加入機前濕料的預烘干和延長濕料在機內烘干時間,再加上密封、保溫以及合理的配套措施,使烘干機生產能力與原單筒式烘干機相比,提高48-80%,單位容積蒸發強度可達120-180kg/m3,標準煤耗僅為6-8kg/t。其技術先進、運行參數合理,操作簡單可行,廣泛應用于各個行業的礦渣、粘土、煤。
產品(pin)結構
三(san)筒(tong)(tong)式烘(hong)干(gan)機(ji)是通過對單筒(tong)(tong)烘(hong)干(gan)機(ji)的單筒(tong)(tong)體(ti)改為套疊(die)在一起的三(san)筒(tong)(tong),以縮(suo)短(duan)烘(hong)干(gan)機(ji)體(ti)的外(wai)形(xing)尺寸。該機(ji)工作時(shi),物料(liao)和熱氣(qi)流依次進入內至(zhi)外(wai)筒(tong)(tong)體(ti),在機(ji)體(ti)Z形(xing)往復(fu)折流后,充分(fen)利用熱能烘(hong)干(gan)物料(liao)后再卸出。
烘(hong)干機筒(tong)體(ti)部分由三個同軸(zhou)水(shui)平放置的內、中、外(wai)筒(tong)套疊組成,這就使筒(tong)體(ti)的截面(mian)(mian)得到充分的利用(yong)。其筒(tong)體(ti)外(wai)形總(zong)長(chang)度(du)約為與之相當的單筒(tong)的30-35%。從而大(da)幅度(du)地減(jian)少占地面(mian)(mian)積和廠(chang)房建筑面(mian)(mian)積。
該機(ji)(ji)的支(zhi)承(cheng)裝(zhuang)置,是(shi)在外(wai)筒(tong)上輪帶(dai)與托輪支(zhi)承(cheng),由電機(ji)(ji)直接(jie)帶(dai)動托輪。通過托輪與輪帶(dai)摩擦,使筒(tong)體轉動。該機(ji)(ji)總體結構緊湊、合理、簡單,為便于磨損件的檢修(xiu)更換,在中間(jian)設(she)計成(cheng)軸向剖分(fen)式(shi),用螺栓固定連接(jie)。
工作(zuo)原(yuan)理
物(wu)(wu)料由供料裝置進(jin)(jin)(jin)入回(hui)轉滾(gun)筒的(de)內層(ceng),實現順流(liu)烘(hong)干,物(wu)(wu)料在內層(ceng)的(de)抄(chao)板下不斷抄(chao)起、散落呈螺旋(xuan)行(xing)(xing)進(jin)(jin)(jin)式實現熱(re)(re)交換,物(wu)(wu)料移(yi)動(dong)至內層(ceng)的(de)另(ling)一端進(jin)(jin)(jin)入中(zhong)層(ceng),進(jin)(jin)(jin)行(xing)(xing)逆流(liu)烘(hong)干,物(wu)(wu)料在中(zhong)層(ceng)不斷地被反復(fu)揚(yang)進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩(liang)步(bu)(bu)退一步(bu)(bu)的(de)行(xing)(xing)進(jin)(jin)(jin)方式,物(wu)(wu)料在中(zhong)層(ceng)既充(chong)分吸(xi)收內層(ceng)滾(gun)筒散發的(de)熱(re)(re)量,又吸(xi)收中(zhong)層(ceng)滾(gun)筒的(de)熱(re)(re)量,同(tong)時(shi)又延長了干燥(zao)(zao)時(shi)間,物(wu)(wu)料在此(ci)達(da)到(dao)(dao)(dao)干燥(zao)(zao)狀態。物(wu)(wu)料行(xing)(xing)至中(zhong)層(ceng)另(ling)一端而落入外(wai)層(ceng),物(wu)(wu)料在外(wai)層(ceng)滾(gun)筒內呈矩形多(duo)回(hui)路方式行(xing)(xing)進(jin)(jin)(jin),達(da)到(dao)(dao)(dao)干燥(zao)(zao)效果(guo)的(de)物(wu)(wu)料在熱(re)(re)風作用下快(kuai)速行(xing)(xing)進(jin)(jin)(jin)排出滾(gun)筒,沒有達(da)到(dao)(dao)(dao)干燥(zao)(zao)效果(guo)的(de)濕物(wu)(wu)料因(yin)自(zi)重而不能快(kuai)速行(xing)(xing)進(jin)(jin)(jin),物(wu)(wu)料在此(ci)矩形抄(chao)板內進(jin)(jin)(jin)行(xing)(xing)充(chong)分干燥(zao)(zao),由此(ci)完成(cheng)干燥(zao)(zao)目(mu)的(de)。
