產品(pin)概(gai)況
回轉式三筒烘(hong)(hong)干(gan)(gan)機(ji)改進原(yuan)單(dan)筒烘(hong)(hong)干(gan)(gan)機(ji)內(nei)部結構，增加(jia)入(ru)機(ji)前濕料的預烘(hong)(hong)干(gan)(gan)和(he)延長(chang)濕料在機(ji)內(nei)烘(hong)(hong)干(gan)(gan)時間(jian)，再加(jia)上密封、保溫以及合(he)(he)理的配套措施，使(shi)烘(hong)(hong)干(gan)(gan)機(ji)生產能(neng)力與原(yuan)單(dan)筒式烘(hong)(hong)干(gan)(gan)機(ji)相比，提高48-80%，單(dan)位容積蒸發(fa)強度可達120-180kg/m3，標準煤耗僅為6-8kg/t。其(qi)技術先(xian)進、運行參數合(he)(he)理，操(cao)作簡單(dan)可行，廣泛應用于各個行業的礦渣、粘土、煤。
產品結構
三筒(tong)(tong)烘(hong)干(gan)(gan)機(ji)是通過對單筒(tong)(tong)烘(hong)干(gan)(gan)機(ji)的(de)單筒(tong)(tong)體(ti)改為套疊在一起(qi)的(de)三筒(tong)(tong)，以縮短烘(hong)干(gan)(gan)機(ji)體(ti)的(de)外形(xing)尺(chi)寸。該(gai)機(ji)工作時，物(wu)料和熱(re)氣流(liu)依次進入內至外筒(tong)(tong)體(ti)，在機(ji)體(ti)Z形(xing)往復(fu)折流(liu)后(hou)，充(chong)分利用熱(re)能烘(hong)干(gan)(gan)物(wu)料后(hou)再卸出。
烘干機(ji)筒(tong)(tong)(tong)體部分(fen)由(you)三(san)個同軸水平(ping)放置的(de)內、中、外筒(tong)(tong)(tong)套疊組成，這就使筒(tong)(tong)(tong)體的(de)截面(mian)得到充分(fen)的(de)利用。其筒(tong)(tong)(tong)體外形總長度約為(wei)與之相當的(de)單筒(tong)(tong)(tong)的(de)30-35%。從(cong)而(er)大幅度地(di)減少占地(di)面(mian)積和(he)廠房建筑面(mian)積。
該機的支(zhi)承(cheng)裝(zhuang)置，是在(zai)外筒上輪(lun)(lun)帶(dai)與托輪(lun)(lun)支(zhi)承(cheng)，由電機直接(jie)帶(dai)動托輪(lun)(lun)。通過(guo)托輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦，使(shi)筒體(ti)(ti)轉(zhuan)動。該機總體(ti)(ti)結構緊(jin)湊、合理、簡單，為(wei)便于磨損件(jian)的檢修更換，在(zai)中間(jian)設(she)計成(cheng)軸(zhou)向(xiang)剖分式，用螺栓(shuan)固(gu)定(ding)連接(jie)。
工作原理
物(wu)(wu)(wu)料(liao)由(you)供料(liao)裝置(zhi)進(jin)(jin)入回轉滾(gun)筒的內(nei)(nei)層(ceng),實(shi)現(xian)順流(liu)烘干(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)在(zai)(zai)內(nei)(nei)層(ceng)的抄(chao)(chao)板下(xia)(xia)不斷抄(chao)(chao)起、散(san)(san)落呈螺(luo)旋行(xing)進(jin)(jin)式(shi)實(shi)現(xian)熱(re)(re)交換，物(wu)(wu)(wu)料(liao)移動至內(nei)(nei)層(ceng)的另(ling)一端進(jin)(jin)入中(zhong)(zhong)層(ceng)，進(jin)(jin)行(xing)逆流(liu)烘干(gan)(gan)(gan)，物(wu)(wu)(wu)料(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)不斷地(di)被反復揚進(jin)(jin)，呈進(jin)(jin)兩步(bu)退(tui)一步(bu)的行(xing)進(jin)(jin)方式(shi)，物(wu)(wu)(wu)料(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)既充分(fen)吸(xi)收內(nei)(nei)層(ceng)滾(gun)筒散(san)(san)發(fa)的熱(re)(re)量(liang)，又(you)吸(xi)收中(zhong)(zhong)層(ceng)滾(gun)筒的熱(re)(re)量(liang)，同時(shi)又(you)延長了干(gan)(gan)(gan)燥(zao)時(shi)間，物(wu)(wu)(wu)料(liao)在(zai)(zai)此(ci)達到干(gan)(gan)(gan)燥(zao)狀態。物(wu)(wu)(wu)料(liao)行(xing)至中(zhong)(zhong)層(ceng)另(ling)一端而落入外(wai)層(ceng)，物(wu)(wu)(wu)料(liao)在(zai)(zai)外(wai)層(ceng)滾(gun)筒內(nei)(nei)呈矩(ju)形多(duo)回路方式(shi)行(xing)進(jin)(jin)，達到干(gan)(gan)(gan)燥(zao)效果的物(wu)(wu)(wu)料(liao)在(zai)(zai)熱(re)(re)風作用下(xia)(xia)快速行(xing)進(jin)(jin)排出滾(gun)筒，沒有達到干(gan)(gan)(gan)燥(zao)效果的濕物(wu)(wu)(wu)料(liao)因自重而不能快速行(xing)進(jin)(jin)，物(wu)(wu)(wu)料(liao)在(zai)(zai)此(ci)矩(ju)形抄(chao)(chao)板內(nei)(nei)進(jin)(jin)行(xing)充分(fen)干(gan)(gan)(gan)燥(zao)，由(you)此(ci)完成干(gan)(gan)(gan)燥(zao)目的。
