產品概況

三筒烘干機是在單筒回轉式烘干機基礎上改進的節能產品。

回轉式三筒(tong)(tong)烘(hong)(hong)干(gan)機(ji)(ji)改進原單(dan)(dan)筒(tong)(tong)烘(hong)(hong)干(gan)機(ji)(ji)內(nei)部結構，增加(jia)入機(ji)(ji)前濕(shi)料的預(yu)烘(hong)(hong)干(gan)和延長濕(shi)料在機(ji)(ji)內(nei)烘(hong)(hong)干(gan)時(shi)間，再加(jia)上密(mi)封(feng)、保(bao)溫以及(ji)合理的配套措施，使烘(hong)(hong)干(gan)機(ji)(ji)生產(chan)能力與原單(dan)(dan)筒(tong)(tong)式烘(hong)(hong)干(gan)機(ji)(ji)相比(bi)，提高48-80%，單(dan)(dan)位容積蒸發(fa)強度(du)可達(da)120-180kg/m3，標準煤耗(hao)僅為6-8kg/t。其技術先進、運(yun)行(xing)參(can)數合理，操(cao)作簡單(dan)(dan)可行(xing)，廣泛應(ying)用于各個行(xing)業的礦渣(zha)、粘土、煤。

產品結構

三筒烘干(gan)機是通過對單筒烘干(gan)機的單筒體(ti)改(gai)為套疊在一起的三筒，以縮短烘干(gan)機體(ti)的外形(xing)尺寸。該機工作時，物料(liao)和熱(re)氣流依次進(jin)入內至外筒體(ti)，在機體(ti)Z形(xing)往復(fu)折流后，充分利用熱(re)能(neng)烘干(gan)物料(liao)后再卸出(chu)。

烘干(gan)機筒(tong)(tong)體(ti)(ti)部分由(you)三個同軸(zhou)水平放置的(de)內、中(zhong)、外筒(tong)(tong)套(tao)疊組成，這就(jiu)使筒(tong)(tong)體(ti)(ti)的(de)截面(mian)得(de)到充分的(de)利用。其筒(tong)(tong)體(ti)(ti)外形(xing)總長度約為(wei)與之相當(dang)的(de)單筒(tong)(tong)的(de)30-35%。從而大幅度地減少占地面(mian)積和(he)廠房建筑面(mian)積。

該(gai)機(ji)的支承裝置，是在外筒上輪(lun)帶與托輪(lun)支承，由(you)電機(ji)直接帶動托輪(lun)。通(tong)過托輪(lun)與輪(lun)帶摩(mo)擦，使筒體轉動。該(gai)機(ji)總體結(jie)構緊湊、合(he)理、簡單，為便(bian)于(yu)磨損(sun)件(jian)的檢(jian)修更換，在中(zhong)間設計(ji)成軸向剖分式，用螺栓(shuan)固定連接。

工作原理

物(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝(zhuang)置進(jin)(jin)(jin)(jin)入回(hui)轉滾(gun)筒(tong)的(de)(de)內(nei)層(ceng)(ceng),實(shi)現(xian)順流烘干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)層(ceng)(ceng)的(de)(de)抄板下不(bu)斷(duan)(duan)抄起、散落呈(cheng)螺旋行(xing)(xing)進(jin)(jin)(jin)(jin)式實(shi)現(xian)熱交換，物(wu)(wu)(wu)料(liao)(liao)移(yi)動至內(nei)層(ceng)(ceng)的(de)(de)另一端(duan)(duan)進(jin)(jin)(jin)(jin)入中層(ceng)(ceng)，進(jin)(jin)(jin)(jin)行(xing)(xing)逆流烘干(gan)(gan)，物(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)不(bu)斷(duan)(duan)地(di)被反復揚進(jin)(jin)(jin)(jin)，呈(cheng)進(jin)(jin)(jin)(jin)兩(liang)步(bu)退(tui)一步(bu)的(de)(de)行(xing)(xing)進(jin)(jin)(jin)(jin)方式，物(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)既充分吸(xi)收(shou)內(nei)層(ceng)(ceng)滾(gun)筒(tong)散發的(de)(de)熱量，又(you)吸(xi)收(shou)中層(ceng)(ceng)滾(gun)筒(tong)的(de)(de)熱量，同時又(you)延長了干(gan)(gan)燥(zao)時間，物(wu)(wu)(wu)料(liao)(liao)在(zai)此達到(dao)干(gan)(gan)燥(zao)狀態(tai)。物(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)至中層(ceng)(ceng)另一端(duan)(duan)而(er)落入外層(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)在(zai)外層(ceng)(ceng)滾(gun)筒(tong)內(nei)呈(cheng)矩(ju)形多回(hui)路方式行(xing)(xing)進(jin)(jin)(jin)(jin)，達到(dao)干(gan)(gan)燥(zao)效果(guo)的(de)(de)物(wu)(wu)(wu)料(liao)(liao)在(zai)熱風作(zuo)用(yong)下快速(su)行(xing)(xing)進(jin)(jin)(jin)(jin)排出(chu)滾(gun)筒(tong)，沒有達到(dao)干(gan)(gan)燥(zao)效果(guo)的(de)(de)濕(shi)物(wu)(wu)(wu)料(liao)(liao)因自重而(er)不(bu)能快速(su)行(xing)(xing)進(jin)(jin)(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)在(zai)此矩(ju)形抄板內(nei)進(jin)(jin)(jin)(jin)行(xing)(xing)充分干(gan)(gan)燥(zao)，由此完成(cheng)干(gan)(gan)燥(zao)目的(de)(de)。
