產品概況
回轉式三筒(tong)烘(hong)干(gan)(gan)機(ji)(ji)(ji)改進原單筒(tong)烘(hong)干(gan)(gan)機(ji)(ji)(ji)內部結構，增加(jia)入機(ji)(ji)(ji)前濕(shi)料(liao)的預烘(hong)干(gan)(gan)和延長(chang)濕(shi)料(liao)在機(ji)(ji)(ji)內烘(hong)干(gan)(gan)時間(jian)，再(zai)加(jia)上密封、保溫以及(ji)合理的配套措(cuo)施，使烘(hong)干(gan)(gan)機(ji)(ji)(ji)生產能力與(yu)原單筒(tong)式烘(hong)干(gan)(gan)機(ji)(ji)(ji)相比(bi)，提高48-80%，單位容(rong)積蒸發強度可(ke)達120-180kg/m3，標(biao)準煤耗僅為6-8kg/t。其技術(shu)先進、運行參數合理，操作簡單可(ke)行，廣泛應(ying)用(yong)于(yu)各個行業的礦渣、粘土、煤。
產(chan)品(pin)結構(gou)
三(san)筒(tong)(tong)(tong)烘(hong)干(gan)(gan)機是通過對單(dan)(dan)筒(tong)(tong)(tong)烘(hong)干(gan)(gan)機的單(dan)(dan)筒(tong)(tong)(tong)體(ti)(ti)(ti)改為套疊在一(yi)起(qi)的三(san)筒(tong)(tong)(tong)，以縮短(duan)烘(hong)干(gan)(gan)機體(ti)(ti)(ti)的外(wai)(wai)形尺寸。該(gai)機工作時，物料和(he)熱氣流(liu)依次進入內至外(wai)(wai)筒(tong)(tong)(tong)體(ti)(ti)(ti)，在機體(ti)(ti)(ti)Z形往復折(zhe)流(liu)后(hou)，充分利(li)用熱能(neng)烘(hong)干(gan)(gan)物料后(hou)再(zai)卸出(chu)。
烘干機筒(tong)體部分由三個(ge)同軸水平放置的(de)內、中、外筒(tong)套(tao)疊組成，這(zhe)就(jiu)使筒(tong)體的(de)截(jie)面得到充分的(de)利用。其筒(tong)體外形總長(chang)度(du)約為(wei)與之相當的(de)單筒(tong)的(de)30-35%。從而大幅度(du)地(di)減少占地(di)面積和廠房建筑面積。
該機的(de)支承裝(zhuang)置(zhi)，是在外筒(tong)上輪(lun)帶與(yu)托輪(lun)支承，由電機直接帶動(dong)(dong)托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶摩擦，使筒(tong)體(ti)轉動(dong)(dong)。該機總體(ti)結構緊(jin)湊、合理、簡單，為便(bian)于(yu)磨損件的(de)檢修更換(huan)，在中間設(she)計成軸向剖(pou)分式，用螺栓固(gu)定(ding)連接。
工作(zuo)原理(li)
物(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置(zhi)進(jin)入(ru)回(hui)轉(zhuan)滾筒(tong)的(de)(de)(de)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng),實(shi)現(xian)順(shun)流烘干(gan),物(wu)(wu)料(liao)(liao)(liao)在內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄板(ban)下(xia)不(bu)斷抄起、散落呈(cheng)螺旋(xuan)行(xing)進(jin)式(shi)(shi)實(shi)現(xian)熱交換，物(wu)(wu)料(liao)(liao)(liao)移動(dong)至內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另一端進(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)行(xing)逆流烘干(gan)，物(wu)(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷地(di)被反復揚(yang)進(jin)，呈(cheng)進(jin)兩步(bu)退一步(bu)的(de)(de)(de)行(xing)進(jin)方式(shi)(shi)，物(wu)(wu)料(liao)(liao)(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)既(ji)充分吸(xi)收(shou)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)散發的(de)(de)(de)熱量，又(you)吸(xi)收(shou)中(zhong)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)的(de)(de)(de)熱量，同時又(you)延長(chang)了干(gan)燥(zao)(zao)時間，物(wu)(wu)料(liao)(liao)(liao)在此達(da)到干(gan)燥(zao)(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另一端而(er)落入(ru)外層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)料(liao)(liao)(liao)在外層(ceng)(ceng)(ceng)(ceng)滾筒(tong)內(nei)(nei)呈(cheng)矩(ju)形(xing)多回(hui)路(lu)方式(shi)(shi)行(xing)進(jin)，達(da)到干(gan)燥(zao)(zao)效果(guo)的(de)(de)(de)物(wu)(wu)料(liao)(liao)(liao)在熱風(feng)作用(yong)下(xia)快速行(xing)進(jin)排出(chu)滾筒(tong)，沒有達(da)到干(gan)燥(zao)(zao)效果(guo)的(de)(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)因(yin)自重(zhong)而(er)不(bu)能快速行(xing)進(jin)，物(wu)(wu)料(liao)(liao)(liao)在此矩(ju)形(xing)抄板(ban)內(nei)(nei)進(jin)行(xing)充分干(gan)燥(zao)(zao)，由此完(wan)成干(gan)燥(zao)(zao)目的(de)(de)(de)。
