產品概況
回轉式(shi)三筒(tong)(tong)(tong)烘(hong)干(gan)機(ji)(ji)改進(jin)原(yuan)單(dan)筒(tong)(tong)(tong)烘(hong)干(gan)機(ji)(ji)內部結構(gou)，增加入(ru)機(ji)(ji)前濕料的(de)預烘(hong)干(gan)和延長濕料在機(ji)(ji)內烘(hong)干(gan)時間，再加上密封(feng)、保溫以及合理的(de)配套(tao)措施，使(shi)烘(hong)干(gan)機(ji)(ji)生產能(neng)力與原(yuan)單(dan)筒(tong)(tong)(tong)式(shi)烘(hong)干(gan)機(ji)(ji)相比，提高48-80%，單(dan)位容積蒸發強度(du)可達(da)120-180kg/m3，標準煤(mei)耗僅為6-8kg/t。其技術先進(jin)、運行(xing)參數合理，操(cao)作(zuo)簡單(dan)可行(xing)，廣泛應用(yong)于各個行(xing)業的(de)礦渣(zha)、粘(zhan)土(tu)、煤(mei)。
產(chan)品結構(gou)
三(san)筒(tong)(tong)烘(hong)(hong)干機(ji)是通過對單(dan)筒(tong)(tong)烘(hong)(hong)干機(ji)的單(dan)筒(tong)(tong)體(ti)改為套疊在一(yi)起的三(san)筒(tong)(tong)，以縮短烘(hong)(hong)干機(ji)體(ti)的外(wai)形尺寸(cun)。該機(ji)工作時，物料和熱氣流(liu)依次進入內(nei)至外(wai)筒(tong)(tong)體(ti)，在機(ji)體(ti)Z形往復折(zhe)流(liu)后(hou)，充(chong)分利用(yong)熱能(neng)烘(hong)(hong)干物料后(hou)再卸出。
烘干(gan)機(ji)筒(tong)(tong)體部(bu)分由三個同軸(zhou)水平放置的內、中、外(wai)(wai)筒(tong)(tong)套疊(die)組成(cheng)，這就使(shi)筒(tong)(tong)體的截(jie)面(mian)得到(dao)充分的利(li)用(yong)。其筒(tong)(tong)體外(wai)(wai)形總長度約為與之相當的單筒(tong)(tong)的30-35%。從(cong)而大幅度地(di)減少占地(di)面(mian)積和(he)廠(chang)房建筑面(mian)積。
該(gai)機的支承裝置，是在外筒上輪帶(dai)與托(tuo)輪支承，由電機直接帶(dai)動(dong)托(tuo)輪。通過托(tuo)輪與輪帶(dai)摩擦，使(shi)筒體轉動(dong)。該(gai)機總(zong)體結構緊(jin)湊、合理、簡單，為便于磨損件的檢修(xiu)更換，在中間設計成軸向剖分式，用螺(luo)栓固定(ding)連接。
工作原理(li)
物(wu)(wu)(wu)料(liao)由供料(liao)裝置進(jin)(jin)(jin)入(ru)回轉滾筒(tong)的(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實(shi)現(xian)順流烘干(gan)(gan),物(wu)(wu)(wu)料(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄(chao)板下(xia)不斷抄(chao)起、散落呈螺(luo)旋(xuan)行(xing)進(jin)(jin)(jin)式實(shi)現(xian)熱交換(huan)，物(wu)(wu)(wu)料(liao)移動至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)另一端(duan)進(jin)(jin)(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)(jin)行(xing)逆流烘干(gan)(gan)，物(wu)(wu)(wu)料(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)不斷地被反復(fu)揚進(jin)(jin)(jin)，呈進(jin)(jin)(jin)兩步(bu)退(tui)一步(bu)的(de)(de)行(xing)進(jin)(jin)(jin)方(fang)式，物(wu)(wu)(wu)料(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸收(shou)內(nei)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)散發(fa)的(de)(de)熱量，又吸收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)的(de)(de)熱量，同時又延長了干(gan)(gan)燥時間，物(wu)(wu)(wu)料(liao)在(zai)此達(da)到干(gan)(gan)燥狀態。物(wu)(wu)(wu)料(liao)行(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)另一端(duan)而(er)落入(ru)外(wai)層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)內(nei)呈矩(ju)形(xing)多(duo)回路(lu)方(fang)式行(xing)進(jin)(jin)(jin)，達(da)到干(gan)(gan)燥效(xiao)果的(de)(de)物(wu)(wu)(wu)料(liao)在(zai)熱風作用下(xia)快(kuai)(kuai)速行(xing)進(jin)(jin)(jin)排(pai)出(chu)滾筒(tong)，沒有達(da)到干(gan)(gan)燥效(xiao)果的(de)(de)濕(shi)物(wu)(wu)(wu)料(liao)因自重而(er)不能(neng)快(kuai)(kuai)速行(xing)進(jin)(jin)(jin)，物(wu)(wu)(wu)料(liao)在(zai)此矩(ju)形(xing)抄(chao)板內(nei)進(jin)(jin)(jin)行(xing)充分干(gan)(gan)燥，由此完成干(gan)(gan)燥目的(de)(de)。
