產(chan)品(pin)概況
回轉式(shi)(shi)三筒烘(hong)(hong)(hong)干(gan)機(ji)(ji)改進(jin)原單筒烘(hong)(hong)(hong)干(gan)機(ji)(ji)內(nei)部結構(gou)，增(zeng)加入機(ji)(ji)前濕料(liao)的預烘(hong)(hong)(hong)干(gan)和延長(chang)濕料(liao)在機(ji)(ji)內(nei)烘(hong)(hong)(hong)干(gan)時(shi)間，再加上密封、保溫以及合理(li)的配套措施，使烘(hong)(hong)(hong)干(gan)機(ji)(ji)生(sheng)產能力與原單筒式(shi)(shi)烘(hong)(hong)(hong)干(gan)機(ji)(ji)相比，提高48-80%，單位容積蒸發強度可達(da)120-180kg/m3，標準煤耗(hao)僅為6-8kg/t。其技術先進(jin)、運行參數合理(li)，操作簡單可行，廣泛(fan)應(ying)用于各個(ge)行業的礦渣、粘土、煤。
產品結構
三筒(tong)(tong)(tong)(tong)烘(hong)干(gan)機(ji)(ji)(ji)是通過對單筒(tong)(tong)(tong)(tong)烘(hong)干(gan)機(ji)(ji)(ji)的(de)單筒(tong)(tong)(tong)(tong)體(ti)(ti)改(gai)為套疊在一起的(de)三筒(tong)(tong)(tong)(tong)，以(yi)縮短(duan)烘(hong)干(gan)機(ji)(ji)(ji)體(ti)(ti)的(de)外(wai)形(xing)尺(chi)寸。該機(ji)(ji)(ji)工作時，物(wu)料和熱氣流依次進(jin)入內至外(wai)筒(tong)(tong)(tong)(tong)體(ti)(ti)，在機(ji)(ji)(ji)體(ti)(ti)Z形(xing)往復折流后，充分(fen)利用熱能烘(hong)干(gan)物(wu)料后再卸(xie)出。
烘干機(ji)筒(tong)體(ti)部分(fen)由三個同軸水平(ping)放置的內、中、外筒(tong)套(tao)疊組成，這就使筒(tong)體(ti)的截面得到充(chong)分(fen)的利(li)用(yong)。其筒(tong)體(ti)外形總長度約為與之相當的單筒(tong)的30-35%。從而大幅度地減少占地面積(ji)和廠房建筑面積(ji)。
該(gai)機的支承裝置，是在外筒上輪(lun)(lun)帶(dai)與(yu)托輪(lun)(lun)支承，由電機直接帶(dai)動托輪(lun)(lun)。通過托輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)摩擦，使筒體轉動。該(gai)機總(zong)體結構緊湊、合理、簡單，為便(bian)于磨損件(jian)的檢(jian)修更換，在中間設計成軸向(xiang)剖分式，用螺栓固定連(lian)接。
工作原理(li)
物(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)(jin)入(ru)回(hui)轉滾(gun)筒的(de)(de)內(nei)層(ceng)(ceng)(ceng),實現(xian)順流(liu)烘干(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)的(de)(de)抄板下不(bu)斷抄起、散落呈螺旋行(xing)(xing)進(jin)(jin)(jin)(jin)式(shi)實現(xian)熱(re)交換(huan)，物(wu)(wu)(wu)(wu)料(liao)(liao)移動(dong)至內(nei)層(ceng)(ceng)(ceng)的(de)(de)另一端進(jin)(jin)(jin)(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)(jin)(jin)行(xing)(xing)逆流(liu)烘干(gan)(gan)，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不(bu)斷地(di)被反復揚(yang)進(jin)(jin)(jin)(jin)，呈進(jin)(jin)(jin)(jin)兩步(bu)退(tui)一步(bu)的(de)(de)行(xing)(xing)進(jin)(jin)(jin)(jin)方(fang)式(shi)，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充分吸收(shou)內(nei)層(ceng)(ceng)(ceng)滾(gun)筒散發(fa)的(de)(de)熱(re)量，又吸收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)滾(gun)筒的(de)(de)熱(re)量，同時又延長了(le)干(gan)(gan)燥(zao)時間，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此達(da)到干(gan)(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)另一端而(er)落入(ru)外層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)滾(gun)筒內(nei)呈矩形多回(hui)路方(fang)式(shi)行(xing)(xing)進(jin)(jin)(jin)(jin)，達(da)到干(gan)(gan)燥(zao)效(xiao)果的(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)熱(re)風作(zuo)用下快(kuai)速行(xing)(xing)進(jin)(jin)(jin)(jin)排出滾(gun)筒，沒有達(da)到干(gan)(gan)燥(zao)效(xiao)果的(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)因自重而(er)不(bu)能快(kuai)速行(xing)(xing)進(jin)(jin)(jin)(jin)，物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此矩形抄板內(nei)進(jin)(jin)(jin)(jin)行(xing)(xing)充分干(gan)(gan)燥(zao)，由此完成干(gan)(gan)燥(zao)目的(de)(de)。
