產(chan)品(pin)概況
回轉(zhuan)式三筒(tong)烘(hong)干(gan)(gan)機(ji)改(gai)進原單(dan)(dan)筒(tong)烘(hong)干(gan)(gan)機(ji)內(nei)部結(jie)構(gou),增加入機(ji)前濕(shi)料的(de)預烘(hong)干(gan)(gan)和(he)延長(chang)濕(shi)料在機(ji)內(nei)烘(hong)干(gan)(gan)時(shi)間,再加上密封、保(bao)溫以及合(he)理的(de)配套措施,使烘(hong)干(gan)(gan)機(ji)生產能力與原單(dan)(dan)筒(tong)式烘(hong)干(gan)(gan)機(ji)相(xiang)比,提高48-80%,單(dan)(dan)位容(rong)積蒸發(fa)強度可達120-180kg/m3,標準煤耗僅(jin)為6-8kg/t。其技術先進、運行(xing)參數合(he)理,操(cao)作簡單(dan)(dan)可行(xing),廣泛應用于各個行(xing)業的(de)礦渣、粘土、煤。
產品(pin)結構
三筒(tong)烘(hong)(hong)(hong)干(gan)機是通過對(dui)單筒(tong)烘(hong)(hong)(hong)干(gan)機的單筒(tong)體(ti)(ti)改為套疊在一起(qi)的三筒(tong),以縮(suo)短烘(hong)(hong)(hong)干(gan)機體(ti)(ti)的外(wai)形(xing)尺寸。該(gai)機工(gong)作時(shi),物料和(he)熱氣流依次進入(ru)內(nei)至外(wai)筒(tong)體(ti)(ti),在機體(ti)(ti)Z形(xing)往復(fu)折流后,充分利用熱能烘(hong)(hong)(hong)干(gan)物料后再卸出。
烘(hong)干機(ji)筒體部分(fen)由(you)三個同軸水平放置的(de)內、中、外筒套(tao)疊組(zu)成,這就使(shi)筒體的(de)截面(mian)(mian)得到充分(fen)的(de)利用。其筒體外形總長度約為(wei)與之相(xiang)當的(de)單筒的(de)30-35%。從而大幅度地減少占地面(mian)(mian)積和廠房建筑(zhu)面(mian)(mian)積。
該機(ji)的支承(cheng)裝(zhuang)置,是在外筒上輪(lun)帶與托(tuo)輪(lun)支承(cheng),由電機(ji)直接(jie)帶動托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶摩擦,使筒體(ti)轉(zhuan)動。該機(ji)總體(ti)結(jie)構緊(jin)湊、合理、簡單(dan),為便于磨損(sun)件的檢修更換,在中間(jian)設計成軸向剖分式(shi),用螺栓(shuan)固定連接(jie)。
工作原理(li)
物(wu)(wu)料(liao)(liao)(liao)由(you)(you)供(gong)料(liao)(liao)(liao)裝(zhuang)置進(jin)(jin)(jin)入回(hui)轉滾筒(tong)的(de)(de)(de)內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng),實現順流烘干(gan),物(wu)(wu)料(liao)(liao)(liao)在內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)板(ban)下(xia)不(bu)(bu)斷(duan)抄(chao)起(qi)、散(san)落(luo)呈螺(luo)旋行(xing)(xing)(xing)進(jin)(jin)(jin)式實現熱交換,物(wu)(wu)料(liao)(liao)(liao)移動至內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另一(yi)端(duan)進(jin)(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)(xing)(xing)逆流烘干(gan),物(wu)(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)不(bu)(bu)斷(duan)地被(bei)反(fan)復揚進(jin)(jin)(jin),呈進(jin)(jin)(jin)兩步(bu)退(tui)一(yi)步(bu)的(de)(de)(de)行(xing)(xing)(xing)進(jin)(jin)(jin)方(fang)式,物(wu)(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)既充(chong)(chong)分(fen)吸收(shou)內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)散(san)發的(de)(de)(de)熱量(liang)(liang),又吸收(shou)中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)的(de)(de)(de)熱量(liang)(liang),同時又延長了干(gan)燥(zao)時間,物(wu)(wu)料(liao)(liao)(liao)在此達到(dao)干(gan)燥(zao)狀態(tai)。物(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)另一(yi)端(duan)而落(luo)入外層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)在外層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾筒(tong)內呈矩(ju)形多回(hui)路方(fang)式行(xing)(xing)(xing)進(jin)(jin)(jin),達到(dao)干(gan)燥(zao)效果(guo)的(de)(de)(de)物(wu)(wu)料(liao)(liao)(liao)在熱風作用下(xia)快速(su)行(xing)(xing)(xing)進(jin)(jin)(jin)排出滾筒(tong),沒有達到(dao)干(gan)燥(zao)效果(guo)的(de)(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)因自重而不(bu)(bu)能快速(su)行(xing)(xing)(xing)進(jin)(jin)(jin),物(wu)(wu)料(liao)(liao)(liao)在此矩(ju)形抄(chao)板(ban)內進(jin)(jin)(jin)行(xing)(xing)(xing)充(chong)(chong)分(fen)干(gan)燥(zao),由(you)(you)此完成干(gan)燥(zao)目的(de)(de)(de)。
