產品概(gai)況(kuang)
回(hui)轉式三(san)筒(tong)(tong)烘(hong)干機(ji)改(gai)進原(yuan)單(dan)(dan)筒(tong)(tong)烘(hong)干機(ji)內(nei)部結構，增加入機(ji)前濕料(liao)(liao)的(de)預烘(hong)干和(he)延長濕料(liao)(liao)在機(ji)內(nei)烘(hong)干時間，再加上(shang)密封、保(bao)溫以及合理(li)的(de)配套措施，使烘(hong)干機(ji)生產能力與(yu)原(yuan)單(dan)(dan)筒(tong)(tong)式烘(hong)干機(ji)相(xiang)比，提高48-80%，單(dan)(dan)位容積蒸發強度(du)可達120-180kg/m3，標準煤耗僅(jin)為6-8kg/t。其(qi)技術先進、運行參數(shu)合理(li)，操作(zuo)簡單(dan)(dan)可行，廣泛應用于(yu)各個(ge)行業的(de)礦渣(zha)、粘土、煤。
產(chan)品結構
三(san)筒(tong)(tong)烘干機(ji)(ji)是通過對單筒(tong)(tong)烘干機(ji)(ji)的單筒(tong)(tong)體(ti)(ti)改為套疊在一起的三(san)筒(tong)(tong)，以(yi)縮短烘干機(ji)(ji)體(ti)(ti)的外(wai)形(xing)尺寸。該機(ji)(ji)工作(zuo)時(shi)，物(wu)料(liao)和(he)熱氣流依次進(jin)入內至(zhi)外(wai)筒(tong)(tong)體(ti)(ti)，在機(ji)(ji)體(ti)(ti)Z形(xing)往復折(zhe)流后，充分利用熱能烘干物(wu)料(liao)后再卸出。
烘干(gan)機筒(tong)(tong)體部分由三個同軸水平放置的(de)(de)內、中、外(wai)筒(tong)(tong)套疊組(zu)成，這就使筒(tong)(tong)體的(de)(de)截面得到充分的(de)(de)利用。其筒(tong)(tong)體外(wai)形總長度約為與之相當(dang)的(de)(de)單筒(tong)(tong)的(de)(de)30-35%。從而大幅度地(di)減(jian)少占(zhan)地(di)面積和廠房建筑面積。
該機(ji)的(de)支(zhi)承(cheng)裝置，是在(zai)外筒上輪帶與托輪支(zhi)承(cheng)，由(you)電機(ji)直接帶動(dong)托輪。通過托輪與輪帶摩擦(ca)，使筒體(ti)轉動(dong)。該機(ji)總體(ti)結構(gou)緊湊、合理、簡(jian)單，為便于磨損件的(de)檢修更換，在(zai)中間設計成(cheng)軸(zhou)向(xiang)剖分式，用(yong)螺栓固定連(lian)接。
工(gong)作(zuo)原理
物(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)入回轉滾筒(tong)(tong)(tong)的(de)(de)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng),實現順流(liu)烘干(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)抄板(ban)下不斷抄起(qi)、散落呈螺旋行(xing)進(jin)式實現熱(re)交(jiao)換，物(wu)(wu)(wu)料(liao)(liao)移動至內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)另(ling)一(yi)端進(jin)入中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)，進(jin)行(xing)逆流(liu)烘干(gan)(gan)(gan)，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)不斷地被反復揚進(jin)，呈進(jin)兩步(bu)退一(yi)步(bu)的(de)(de)行(xing)進(jin)方式，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)既充分吸收內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)(tong)散發(fa)的(de)(de)熱(re)量(liang)，又(you)吸收中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)(tong)的(de)(de)熱(re)量(liang)，同時又(you)延長了干(gan)(gan)(gan)燥(zao)(zao)(zao)時間，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此達到干(gan)(gan)(gan)燥(zao)(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)行(xing)至中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)另(ling)一(yi)端而落入外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)(tong)內(nei)(nei)呈矩(ju)形(xing)多(duo)回路方式行(xing)進(jin)，達到干(gan)(gan)(gan)燥(zao)(zao)(zao)效(xiao)果的(de)(de)物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)熱(re)風作用(yong)下快速(su)行(xing)進(jin)排(pai)出滾筒(tong)(tong)(tong)，沒有(you)達到干(gan)(gan)(gan)燥(zao)(zao)(zao)效(xiao)果的(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)因自重(zhong)而不能快速(su)行(xing)進(jin)，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此矩(ju)形(xing)抄板(ban)內(nei)(nei)進(jin)行(xing)充分干(gan)(gan)(gan)燥(zao)(zao)(zao)，由此完成干(gan)(gan)(gan)燥(zao)(zao)(zao)目(mu)的(de)(de)。
