產(chan)品概況
回(hui)轉式三筒烘(hong)(hong)(hong)干(gan)(gan)機(ji)改(gai)進(jin)原單(dan)筒烘(hong)(hong)(hong)干(gan)(gan)機(ji)內部結(jie)構，增(zeng)加入機(ji)前(qian)濕料的(de)預烘(hong)(hong)(hong)干(gan)(gan)和延(yan)長濕料在機(ji)內烘(hong)(hong)(hong)干(gan)(gan)時(shi)間，再加上密封、保溫以及(ji)合(he)理(li)的(de)配套措(cuo)施，使烘(hong)(hong)(hong)干(gan)(gan)機(ji)生(sheng)產能力與原單(dan)筒式烘(hong)(hong)(hong)干(gan)(gan)機(ji)相比(bi)，提高(gao)48-80%，單(dan)位容(rong)積蒸發強度(du)可達120-180kg/m3，標準煤耗僅為(wei)6-8kg/t。其(qi)技(ji)術(shu)先進(jin)、運行(xing)參(can)數合(he)理(li)，操作(zuo)簡單(dan)可行(xing)，廣泛應用(yong)于(yu)各個行(xing)業的(de)礦渣(zha)、粘土、煤。
產品結構(gou)
三筒(tong)烘(hong)(hong)干機(ji)是通過對單(dan)筒(tong)烘(hong)(hong)干機(ji)的(de)單(dan)筒(tong)體改為套疊(die)在一起的(de)三筒(tong)，以縮(suo)短烘(hong)(hong)干機(ji)體的(de)外形尺寸。該(gai)機(ji)工(gong)作時，物料(liao)和(he)熱氣流(liu)依次進(jin)入內至外筒(tong)體，在機(ji)體Z形往復(fu)折流(liu)后，充分(fen)利(li)用熱能(neng)烘(hong)(hong)干物料(liao)后再卸(xie)出(chu)。
烘干機筒(tong)(tong)體部分(fen)由三個同軸水平(ping)放置(zhi)的內(nei)、中(zhong)、外筒(tong)(tong)套疊(die)組成(cheng)，這就(jiu)使筒(tong)(tong)體的截面(mian)得到充分(fen)的利用。其筒(tong)(tong)體外形總長度約為(wei)與之相(xiang)當的單筒(tong)(tong)的30-35%。從而(er)大(da)幅度地減少(shao)占地面(mian)積(ji)和廠房建筑面(mian)積(ji)。
該(gai)機的支承裝置(zhi)，是(shi)在(zai)外筒上輪(lun)(lun)帶與(yu)托(tuo)輪(lun)(lun)支承，由電機直接(jie)帶動托(tuo)輪(lun)(lun)。通(tong)過托(tuo)輪(lun)(lun)與(yu)輪(lun)(lun)帶摩擦(ca)，使筒體轉動。該(gai)機總體結構緊(jin)湊、合理、簡(jian)單(dan)，為便于磨(mo)損件的檢(jian)修更換，在(zai)中間(jian)設計成軸向剖分式(shi)，用螺栓(shuan)固定連接(jie)。
工作(zuo)原理
物(wu)(wu)料(liao)由供料(liao)裝置(zhi)進(jin)(jin)(jin)入(ru)(ru)回轉滾(gun)筒(tong)的內(nei)(nei)層(ceng)(ceng),實現(xian)順流烘干(gan),物(wu)(wu)料(liao)在(zai)(zai)內(nei)(nei)層(ceng)(ceng)的抄(chao)板下(xia)(xia)不斷(duan)抄(chao)起、散落呈螺旋行(xing)進(jin)(jin)(jin)式實現(xian)熱交換(huan)，物(wu)(wu)料(liao)移(yi)動(dong)至內(nei)(nei)層(ceng)(ceng)的另一(yi)(yi)端進(jin)(jin)(jin)入(ru)(ru)中(zhong)層(ceng)(ceng)，進(jin)(jin)(jin)行(xing)逆(ni)流烘干(gan)，物(wu)(wu)料(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)不斷(duan)地被反復揚進(jin)(jin)(jin)，呈進(jin)(jin)(jin)兩步退一(yi)(yi)步的行(xing)進(jin)(jin)(jin)方式，物(wu)(wu)料(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)既充分吸收內(nei)(nei)層(ceng)(ceng)滾(gun)筒(tong)散發的熱量(liang)，又吸收中(zhong)層(ceng)(ceng)滾(gun)筒(tong)的熱量(liang)，同時又延長了干(gan)燥(zao)(zao)(zao)時間(jian)，物(wu)(wu)料(liao)在(zai)(zai)此達(da)到(dao)干(gan)燥(zao)(zao)(zao)狀態(tai)。物(wu)(wu)料(liao)行(xing)至中(zhong)層(ceng)(ceng)另一(yi)(yi)端而落入(ru)(ru)外(wai)層(ceng)(ceng)，物(wu)(wu)料(liao)在(zai)(zai)外(wai)層(ceng)(ceng)滾(gun)筒(tong)內(nei)(nei)呈矩形多(duo)回路(lu)方式行(xing)進(jin)(jin)(jin)，達(da)到(dao)干(gan)燥(zao)(zao)(zao)效果(guo)的物(wu)(wu)料(liao)在(zai)(zai)熱風作用下(xia)(xia)快速(su)行(xing)進(jin)(jin)(jin)排出滾(gun)筒(tong)，沒(mei)有達(da)到(dao)干(gan)燥(zao)(zao)(zao)效果(guo)的濕物(wu)(wu)料(liao)因自重而不能快速(su)行(xing)進(jin)(jin)(jin)，物(wu)(wu)料(liao)在(zai)(zai)此矩形抄(chao)板內(nei)(nei)進(jin)(jin)(jin)行(xing)充分干(gan)燥(zao)(zao)(zao)，由此完成干(gan)燥(zao)(zao)(zao)目(mu)的。
