產(chan)品概況
回(hui)轉式三筒烘(hong)(hong)干(gan)(gan)機改進(jin)原單(dan)筒烘(hong)(hong)干(gan)(gan)機內(nei)部(bu)結構(gou),增加入機前濕(shi)料(liao)的(de)預烘(hong)(hong)干(gan)(gan)和延長(chang)濕(shi)料(liao)在機內(nei)烘(hong)(hong)干(gan)(gan)時間,再加上密封(feng)、保溫以及合理的(de)配套措施,使(shi)烘(hong)(hong)干(gan)(gan)機生產(chan)能力與原單(dan)筒式烘(hong)(hong)干(gan)(gan)機相比(bi),提高48-80%,單(dan)位容積蒸發(fa)強(qiang)度可(ke)達(da)120-180kg/m3,標(biao)準煤耗僅為6-8kg/t。其(qi)技術(shu)先進(jin)、運(yun)行參(can)數合理,操作簡(jian)單(dan)可(ke)行,廣(guang)泛(fan)應用于各個行業的(de)礦渣(zha)、粘土、煤。
產品結(jie)構
三筒(tong)烘干機(ji)是(shi)通過對單筒(tong)烘干機(ji)的單筒(tong)體(ti)改(gai)為套疊在(zai)一起的三筒(tong),以(yi)縮短烘干機(ji)體(ti)的外形(xing)尺寸。該機(ji)工作時,物(wu)(wu)料(liao)和(he)熱氣流依次進入內(nei)至外筒(tong)體(ti),在(zai)機(ji)體(ti)Z形(xing)往復(fu)折流后,充分(fen)利用熱能烘干物(wu)(wu)料(liao)后再(zai)卸出。
烘干機筒(tong)(tong)(tong)體(ti)部分由三個同(tong)軸水平(ping)放置的內(nei)、中、外(wai)筒(tong)(tong)(tong)套(tao)疊組成(cheng),這就使筒(tong)(tong)(tong)體(ti)的截面得到充分的利用。其(qi)筒(tong)(tong)(tong)體(ti)外(wai)形(xing)總長度約為與之相當的單筒(tong)(tong)(tong)的30-35%。從(cong)而大幅度地減少占地面積(ji)和廠房建筑(zhu)面積(ji)。
該(gai)機(ji)的支承裝(zhuang)置,是在(zai)外筒上輪(lun)(lun)帶與托輪(lun)(lun)支承,由電機(ji)直接帶動(dong)托輪(lun)(lun)。通(tong)過托輪(lun)(lun)與輪(lun)(lun)帶摩擦(ca),使筒體轉動(dong)。該(gai)機(ji)總體結構緊湊、合理(li)、簡(jian)單,為便(bian)于磨損件(jian)的檢修(xiu)更換,在(zai)中間設計(ji)成(cheng)軸向剖分式,用螺栓固定連接。
工作原理(li)
物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)由(you)供(gong)料(liao)(liao)(liao)(liao)(liao)裝置進(jin)(jin)(jin)(jin)入(ru)回(hui)轉滾(gun)筒的內(nei)(nei)(nei)層(ceng),實現(xian)順(shun)流烘干(gan)(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)內(nei)(nei)(nei)層(ceng)的抄板(ban)下不斷抄起(qi)、散落呈螺旋行進(jin)(jin)(jin)(jin)式實現(xian)熱(re)交(jiao)換,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)移動至內(nei)(nei)(nei)層(ceng)的另一(yi)端(duan)進(jin)(jin)(jin)(jin)入(ru)中(zhong)(zhong)層(ceng),進(jin)(jin)(jin)(jin)行逆流烘干(gan)(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)不斷地被反復揚進(jin)(jin)(jin)(jin),呈進(jin)(jin)(jin)(jin)兩步(bu)退一(yi)步(bu)的行進(jin)(jin)(jin)(jin)方式,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)既(ji)充(chong)(chong)分吸收(shou)(shou)內(nei)(nei)(nei)層(ceng)滾(gun)筒散發的熱(re)量,又吸收(shou)(shou)中(zhong)(zhong)層(ceng)滾(gun)筒的熱(re)量,同時又延長了(le)干(gan)(gan)(gan)(gan)燥(zao)(zao)時間,物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)此達到干(gan)(gan)(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)行至中(zhong)(zhong)層(ceng)另一(yi)端(duan)而(er)落入(ru)外層(ceng),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)外層(ceng)滾(gun)筒內(nei)(nei)(nei)呈矩(ju)形多(duo)回(hui)路(lu)方式行進(jin)(jin)(jin)(jin),達到干(gan)(gan)(gan)(gan)燥(zao)(zao)效果(guo)的物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)熱(re)風作用下快(kuai)速行進(jin)(jin)(jin)(jin)排出滾(gun)筒,沒有(you)達到干(gan)(gan)(gan)(gan)燥(zao)(zao)效果(guo)的濕物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)因(yin)自重而(er)不能快(kuai)速行進(jin)(jin)(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)此矩(ju)形抄板(ban)內(nei)(nei)(nei)進(jin)(jin)(jin)(jin)行充(chong)(chong)分干(gan)(gan)(gan)(gan)燥(zao)(zao),由(you)此完成干(gan)(gan)(gan)(gan)燥(zao)(zao)目的。
