產(chan)品概況
回轉(zhuan)式三筒烘(hong)(hong)(hong)干機(ji)改進原(yuan)單(dan)(dan)(dan)筒烘(hong)(hong)(hong)干機(ji)內部結構，增加入機(ji)前(qian)濕(shi)料(liao)的預烘(hong)(hong)(hong)干和延長濕(shi)料(liao)在機(ji)內烘(hong)(hong)(hong)干時間，再加上(shang)密封、保溫以(yi)及(ji)合理的配套措(cuo)施，使烘(hong)(hong)(hong)干機(ji)生產能力與(yu)原(yuan)單(dan)(dan)(dan)筒式烘(hong)(hong)(hong)干機(ji)相(xiang)比，提高48-80%，單(dan)(dan)(dan)位容積蒸發(fa)強(qiang)度(du)可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進、運(yun)行(xing)(xing)參(can)數(shu)合理，操(cao)作簡單(dan)(dan)(dan)可行(xing)(xing)，廣泛(fan)應用于(yu)各個行(xing)(xing)業的礦(kuang)渣(zha)、粘(zhan)土、煤。
產品結構
三筒(tong)烘(hong)(hong)干(gan)機(ji)是通過對單(dan)筒(tong)烘(hong)(hong)干(gan)機(ji)的單(dan)筒(tong)體改為套疊(die)在一起的三筒(tong)，以縮短烘(hong)(hong)干(gan)機(ji)體的外形尺寸。該機(ji)工作時，物料(liao)和熱氣流依次進入內至外筒(tong)體，在機(ji)體Z形往復折流后(hou)，充(chong)分利用(yong)熱能(neng)烘(hong)(hong)干(gan)物料(liao)后(hou)再卸出。
烘干(gan)機(ji)筒(tong)(tong)體(ti)部分(fen)由三個(ge)同軸水平放置的(de)(de)內(nei)、中、外(wai)(wai)筒(tong)(tong)套疊組成，這(zhe)就使筒(tong)(tong)體(ti)的(de)(de)截面(mian)得到充分(fen)的(de)(de)利用。其筒(tong)(tong)體(ti)外(wai)(wai)形總(zong)長度約為與(yu)之相當的(de)(de)單(dan)筒(tong)(tong)的(de)(de)30-35%。從而大幅度地減少(shao)占(zhan)地面(mian)積和廠房(fang)建筑(zhu)面(mian)積。
該機(ji)的支(zhi)承裝置，是在外筒上輪(lun)帶(dai)(dai)(dai)與托(tuo)輪(lun)支(zhi)承，由電機(ji)直接帶(dai)(dai)(dai)動(dong)(dong)托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶(dai)(dai)(dai)摩(mo)擦，使筒體轉動(dong)(dong)。該機(ji)總體結構緊湊、合理(li)、簡單，為便于磨損件(jian)的檢修更(geng)換，在中間設計(ji)成軸(zhou)向剖分式，用螺栓固定(ding)連接。
工作(zuo)原理(li)
物(wu)料由(you)供料裝置進(jin)入回(hui)轉滾(gun)筒(tong)的(de)(de)(de)內(nei)(nei)層(ceng)(ceng),實現(xian)順(shun)流(liu)烘干(gan),物(wu)料在內(nei)(nei)層(ceng)(ceng)的(de)(de)(de)抄(chao)板(ban)下(xia)不(bu)斷(duan)抄(chao)起、散落呈螺旋行(xing)進(jin)式(shi)實現(xian)熱交換，物(wu)料移動至內(nei)(nei)層(ceng)(ceng)的(de)(de)(de)另一(yi)端(duan)進(jin)入中(zhong)(zhong)層(ceng)(ceng)，進(jin)行(xing)逆(ni)流(liu)烘干(gan)，物(wu)料在中(zhong)(zhong)層(ceng)(ceng)不(bu)斷(duan)地被反復揚進(jin)，呈進(jin)兩步(bu)(bu)退一(yi)步(bu)(bu)的(de)(de)(de)行(xing)進(jin)方式(shi)，物(wu)料在中(zhong)(zhong)層(ceng)(ceng)既(ji)充分吸收內(nei)(nei)層(ceng)(ceng)滾(gun)筒(tong)散發的(de)(de)(de)熱量，又(you)吸收中(zhong)(zhong)層(ceng)(ceng)滾(gun)筒(tong)的(de)(de)(de)熱量，同時又(you)延長了干(gan)燥(zao)(zao)時間，物(wu)料在此(ci)達(da)到干(gan)燥(zao)(zao)狀態。物(wu)料行(xing)至中(zhong)(zhong)層(ceng)(ceng)另一(yi)端(duan)而落入外層(ceng)(ceng)，物(wu)料在外層(ceng)(ceng)滾(gun)筒(tong)內(nei)(nei)呈矩形多(duo)回(hui)路(lu)方式(shi)行(xing)進(jin)，達(da)到干(gan)燥(zao)(zao)效果的(de)(de)(de)物(wu)料在熱風作(zuo)用(yong)下(xia)快速行(xing)進(jin)排出滾(gun)筒(tong)，沒有(you)達(da)到干(gan)燥(zao)(zao)效果的(de)(de)(de)濕(shi)物(wu)料因自重而不(bu)能快速行(xing)進(jin)，物(wu)料在此(ci)矩形抄(chao)板(ban)內(nei)(nei)進(jin)行(xing)充分干(gan)燥(zao)(zao)，由(you)此(ci)完成干(gan)燥(zao)(zao)目的(de)(de)(de)。
