產品概(gai)況(kuang)
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
三筒(tong)(tong)式烘干機(ji)(ji)是通過(guo)對單筒(tong)(tong)烘干機(ji)(ji)的(de)單筒(tong)(tong)體(ti)改為套(tao)疊在一(yi)起的(de)三筒(tong)(tong),以縮(suo)短烘干機(ji)(ji)體(ti)的(de)外形尺寸。該機(ji)(ji)工作(zuo)時,物料(liao)和(he)熱氣(qi)流(liu)依(yi)次進入內至外筒(tong)(tong)體(ti),在機(ji)(ji)體(ti)Z形往復折(zhe)流(liu)后,充分利用熱能烘干物料(liao)后再卸出。
烘干機(ji)筒(tong)體部分(fen)由(you)三個同軸(zhou)水平放(fang)置的(de)內、中(zhong)、外筒(tong)套疊組(zu)成(cheng),這(zhe)就使筒(tong)體的(de)截(jie)面得到充分(fen)的(de)利(li)用。其筒(tong)體外形總長度(du)約為(wei)與之相(xiang)當的(de)單筒(tong)的(de)30-35%。從而大幅度(du)地(di)減少占地(di)面積和廠房(fang)建筑(zhu)面積。
該機的支(zhi)(zhi)承裝置(zhi),是在(zai)外筒上輪(lun)帶與(yu)托(tuo)輪(lun)支(zhi)(zhi)承,由(you)電機直接(jie)(jie)帶動托(tuo)輪(lun)。通過托(tuo)輪(lun)與(yu)輪(lun)帶摩擦,使筒體轉動。該機總體結構緊湊、合理、簡單,為便于(yu)磨損件(jian)的檢(jian)修更換,在(zai)中間設計成(cheng)軸向剖分式,用螺栓固定連接(jie)(jie)。
工作原理
物(wu)(wu)(wu)(wu)料(liao)由(you)供料(liao)裝置進(jin)入回轉滾(gun)(gun)筒(tong)的內(nei)(nei)層(ceng)(ceng)(ceng),實現順(shun)流烘(hong)干,物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)內(nei)(nei)層(ceng)(ceng)(ceng)的抄(chao)板下不斷(duan)抄(chao)起、散(san)(san)落呈螺旋行(xing)進(jin)式(shi)實現熱交(jiao)換,物(wu)(wu)(wu)(wu)料(liao)移(yi)動至內(nei)(nei)層(ceng)(ceng)(ceng)的另(ling)一(yi)端進(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng),進(jin)行(xing)逆流烘(hong)干,物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不斷(duan)地被反(fan)復揚進(jin),呈進(jin)兩步退一(yi)步的行(xing)進(jin)方式(shi),物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充分吸收(shou)(shou)內(nei)(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散(san)(san)發的熱量(liang),又(you)吸收(shou)(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的熱量(liang),同時又(you)延長了干燥(zao)(zao)時間(jian),物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)此(ci)達到干燥(zao)(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)行(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)另(ling)一(yi)端而落入外層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)外層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)(nei)呈矩形多回路方式(shi)行(xing)進(jin),達到干燥(zao)(zao)效(xiao)果的物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)熱風(feng)作(zuo)用下快(kuai)速(su)行(xing)進(jin)排出滾(gun)(gun)筒(tong),沒(mei)有達到干燥(zao)(zao)效(xiao)果的濕物(wu)(wu)(wu)(wu)料(liao)因自重而不能快(kuai)速(su)行(xing)進(jin),物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)此(ci)矩形抄(chao)板內(nei)(nei)進(jin)行(xing)充分干燥(zao)(zao),由(you)此(ci)完成干燥(zao)(zao)目的。
