產品(pin)概(gai)況
回轉式(shi)三筒烘(hong)(hong)干(gan)機改進原單(dan)筒烘(hong)(hong)干(gan)機內部結構，增加入(ru)機前濕料(liao)的預烘(hong)(hong)干(gan)和(he)延長濕料(liao)在機內烘(hong)(hong)干(gan)時間，再加上密封(feng)、保溫以及合理的配套措施，使烘(hong)(hong)干(gan)機生產(chan)能(neng)力與(yu)原單(dan)筒式(shi)烘(hong)(hong)干(gan)機相比，提高48-80%，單(dan)位容(rong)積蒸(zheng)發強(qiang)度可(ke)達120-180kg/m3，標(biao)準煤耗僅為6-8kg/t。其技術(shu)先進、運行參數(shu)合理，操作簡(jian)單(dan)可(ke)行，廣泛應用(yong)于(yu)各個行業的礦渣、粘土、煤。
產(chan)品結構(gou)
三(san)筒(tong)(tong)烘干機是通過對(dui)單(dan)筒(tong)(tong)烘干機的(de)單(dan)筒(tong)(tong)體改為套疊在一起的(de)三(san)筒(tong)(tong)，以縮短(duan)烘干機體的(de)外形尺寸。該(gai)機工作時，物(wu)料和(he)熱氣(qi)流(liu)依(yi)次進入內至外筒(tong)(tong)體，在機體Z形往復(fu)折流(liu)后(hou)(hou)，充分利用熱能烘干物(wu)料后(hou)(hou)再卸出。
烘(hong)干機筒體(ti)部分由三個(ge)同(tong)軸(zhou)水(shui)平放(fang)置的內(nei)、中、外筒套疊組成，這就使筒體(ti)的截面(mian)(mian)得到充分的利用。其筒體(ti)外形總長(chang)度約為與之相當(dang)的單筒的30-35%。從(cong)而大幅度地減少占地面(mian)(mian)積(ji)和廠房(fang)建(jian)筑面(mian)(mian)積(ji)。
該(gai)機的(de)支承(cheng)裝(zhuang)置，是(shi)在(zai)外筒(tong)上輪(lun)帶(dai)與(yu)托(tuo)輪(lun)支承(cheng)，由電機直接(jie)帶(dai)動(dong)托(tuo)輪(lun)。通過(guo)托(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩擦，使筒(tong)體(ti)轉動(dong)。該(gai)機總體(ti)結構緊(jin)湊、合理、簡(jian)單，為(wei)便(bian)于磨(mo)損件的(de)檢修更換(huan)，在(zai)中(zhong)間設計(ji)成(cheng)軸(zhou)向剖分式，用螺(luo)栓固(gu)定連接(jie)。
工作原理(li)
物(wu)(wu)(wu)(wu)料(liao)由供料(liao)裝(zhuang)置進(jin)(jin)入(ru)回轉滾(gun)筒的(de)(de)(de)內(nei)層(ceng)(ceng)(ceng),實現(xian)順流(liu)烘干,物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)板下(xia)不(bu)斷抄(chao)起(qi)、散落呈螺旋行(xing)(xing)(xing)進(jin)(jin)式(shi)實現(xian)熱(re)(re)(re)交換，物(wu)(wu)(wu)(wu)料(liao)移動(dong)至(zhi)內(nei)層(ceng)(ceng)(ceng)的(de)(de)(de)另一端進(jin)(jin)入(ru)中層(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)(xing)(xing)逆(ni)流(liu)烘干，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)不(bu)斷地被反復揚進(jin)(jin)，呈進(jin)(jin)兩(liang)步(bu)退一步(bu)的(de)(de)(de)行(xing)(xing)(xing)進(jin)(jin)方式(shi)，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)既充分(fen)吸(xi)(xi)收內(nei)層(ceng)(ceng)(ceng)滾(gun)筒散發(fa)的(de)(de)(de)熱(re)(re)(re)量，又吸(xi)(xi)收中層(ceng)(ceng)(ceng)滾(gun)筒的(de)(de)(de)熱(re)(re)(re)量，同(tong)時(shi)又延長(chang)了(le)干燥(zao)(zao)時(shi)間，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)此達到(dao)干燥(zao)(zao)狀(zhuang)態。物(wu)(wu)(wu)(wu)料(liao)行(xing)(xing)(xing)至(zhi)中層(ceng)(ceng)(ceng)另一端而落入(ru)外層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)滾(gun)筒內(nei)呈矩形(xing)多回路方式(shi)行(xing)(xing)(xing)進(jin)(jin)，達到(dao)干燥(zao)(zao)效果的(de)(de)(de)物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)熱(re)(re)(re)風作用下(xia)快速(su)行(xing)(xing)(xing)進(jin)(jin)排出滾(gun)筒，沒有達到(dao)干燥(zao)(zao)效果的(de)(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)因自重而不(bu)能(neng)快速(su)行(xing)(xing)(xing)進(jin)(jin)，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)此矩形(xing)抄(chao)板內(nei)進(jin)(jin)行(xing)(xing)(xing)充分(fen)干燥(zao)(zao)，由此完成干燥(zao)(zao)目的(de)(de)(de)。
