產品概況
回轉式三筒(tong)烘干(gan)機(ji)改進(jin)原(yuan)單(dan)筒(tong)烘干(gan)機(ji)內(nei)部結構，增加(jia)入機(ji)前濕料的預烘干(gan)和延長濕料在機(ji)內(nei)烘干(gan)時間(jian)，再加(jia)上密(mi)封(feng)、保溫(wen)以及(ji)合理(li)的配套措施，使烘干(gan)機(ji)生產能力與(yu)原(yuan)單(dan)筒(tong)式烘干(gan)機(ji)相比，提高(gao)48-80%，單(dan)位容積(ji)蒸發強度(du)可達120-180kg/m3，標準煤耗(hao)僅為6-8kg/t。其技術先進(jin)、運(yun)行(xing)參數(shu)合理(li)，操作(zuo)簡單(dan)可行(xing)，廣泛(fan)應用于各個(ge)行(xing)業的礦渣、粘土、煤。
產(chan)品結構
三筒(tong)(tong)烘(hong)(hong)(hong)干機(ji)(ji)是(shi)通過對單(dan)筒(tong)(tong)烘(hong)(hong)(hong)干機(ji)(ji)的單(dan)筒(tong)(tong)體改為套疊(die)在一起的三筒(tong)(tong)，以縮短烘(hong)(hong)(hong)干機(ji)(ji)體的外(wai)形尺寸。該機(ji)(ji)工作時，物料(liao)和熱(re)氣流依次(ci)進入內至外(wai)筒(tong)(tong)體，在機(ji)(ji)體Z形往復折流后，充分利用熱(re)能(neng)烘(hong)(hong)(hong)干物料(liao)后再卸出。
烘干機筒(tong)(tong)體部分(fen)由(you)三個(ge)同(tong)軸水(shui)平放(fang)置的(de)內、中、外(wai)筒(tong)(tong)套疊組成(cheng)，這就使(shi)筒(tong)(tong)體的(de)截面得到(dao)充(chong)分(fen)的(de)利用。其筒(tong)(tong)體外(wai)形總長度約為與之相當(dang)的(de)單筒(tong)(tong)的(de)30-35%。從(cong)而大幅度地減少占地面積和廠(chang)房建(jian)筑面積。
該機(ji)的(de)支承裝置，是在外筒上輪(lun)帶(dai)(dai)與托(tuo)輪(lun)支承，由電(dian)機(ji)直(zhi)接帶(dai)(dai)動(dong)托(tuo)輪(lun)。通過(guo)托(tuo)輪(lun)與輪(lun)帶(dai)(dai)摩(mo)擦，使筒體轉動(dong)。該機(ji)總體結構緊湊、合(he)理、簡單(dan)，為(wei)便于磨損件的(de)檢(jian)修更(geng)換，在中間(jian)設計(ji)成(cheng)軸向剖分(fen)式，用螺栓固定連接。
工作(zuo)原理(li)
物(wu)(wu)料(liao)由供(gong)料(liao)裝置進(jin)入回(hui)轉(zhuan)滾筒(tong)的(de)(de)內(nei)層(ceng)(ceng)(ceng),實現順流烘干(gan)(gan),物(wu)(wu)料(liao)在內(nei)層(ceng)(ceng)(ceng)的(de)(de)抄板(ban)下(xia)不(bu)斷抄起(qi)、散落呈螺旋行(xing)(xing)進(jin)式實現熱(re)(re)交換，物(wu)(wu)料(liao)移動(dong)至內(nei)層(ceng)(ceng)(ceng)的(de)(de)另一端(duan)進(jin)入中(zhong)層(ceng)(ceng)(ceng)，進(jin)行(xing)(xing)逆流烘干(gan)(gan)，物(wu)(wu)料(liao)在中(zhong)層(ceng)(ceng)(ceng)不(bu)斷地被(bei)反復(fu)揚(yang)進(jin)，呈進(jin)兩(liang)步退一步的(de)(de)行(xing)(xing)進(jin)方式，物(wu)(wu)料(liao)在中(zhong)層(ceng)(ceng)(ceng)既充分吸收內(nei)層(ceng)(ceng)(ceng)滾筒(tong)散發的(de)(de)熱(re)(re)量，又吸收中(zhong)層(ceng)(ceng)(ceng)滾筒(tong)的(de)(de)熱(re)(re)量，同時又延長了干(gan)(gan)燥時間，物(wu)(wu)料(liao)在此(ci)達(da)到干(gan)(gan)燥狀態。物(wu)(wu)料(liao)行(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)另一端(duan)而(er)落入外(wai)層(ceng)(ceng)(ceng)，物(wu)(wu)料(liao)在外(wai)層(ceng)(ceng)(ceng)滾筒(tong)內(nei)呈矩形(xing)多回(hui)路(lu)方式行(xing)(xing)進(jin)，達(da)到干(gan)(gan)燥效(xiao)果的(de)(de)物(wu)(wu)料(liao)在熱(re)(re)風作(zuo)用下(xia)快(kuai)速(su)行(xing)(xing)進(jin)排(pai)出(chu)滾筒(tong)，沒有達(da)到干(gan)(gan)燥效(xiao)果的(de)(de)濕物(wu)(wu)料(liao)因自(zi)重而(er)不(bu)能快(kuai)速(su)行(xing)(xing)進(jin)，物(wu)(wu)料(liao)在此(ci)矩形(xing)抄板(ban)內(nei)進(jin)行(xing)(xing)充分干(gan)(gan)燥，由此(ci)完成干(gan)(gan)燥目(mu)的(de)(de)。
