產品結構
大型三筒烘干機是通過對單筒烘干機的單筒體改為套疊在一起的三筒,以縮短烘干機體的外形尺寸。該機工作時,物料和熱氣流依次進入內至外筒體,在機體Z形往復折流后,充分利用熱能烘干物料后再卸出。
烘干機筒(tong)體(ti)部分由(you)三個同(tong)軸(zhou)水平放(fang)置的內、中(zhong)、外筒(tong)套疊組成,這(zhe)就使筒(tong)體(ti)的截面得到充分的利用。其筒(tong)體(ti)外形(xing)總長度約為與之(zhi)相當(dang)的單(dan)筒(tong)的30-35%。從而大(da)幅(fu)度地減(jian)少占地面積和廠(chang)房建(jian)筑面積。
該(gai)(gai)機(ji)的(de)(de)支承裝置,是在外筒上輪(lun)帶與(yu)托輪(lun)支承,由電機(ji)直接帶動(dong)托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶摩擦,使筒體轉動(dong)。該(gai)(gai)機(ji)總體結構緊(jin)湊、合理、簡單,為便于磨損件的(de)(de)檢(jian)修更換(huan),在中間設計成軸向剖分式,用螺栓固(gu)定連接。
工作原理(li)
物(wu)料(liao)(liao)(liao)(liao)由(you)(you)供料(liao)(liao)(liao)(liao)裝置進(jin)(jin)入(ru)回轉滾(gun)(gun)筒(tong)的(de)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng),實現順流烘干(gan)(gan),物(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)抄板(ban)下不(bu)(bu)(bu)斷(duan)抄起、散(san)落呈螺(luo)旋行(xing)(xing)(xing)進(jin)(jin)式實現熱(re)交換,物(wu)料(liao)(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)另一(yi)端(duan)進(jin)(jin)入(ru)中層(ceng)(ceng)(ceng)(ceng)(ceng),進(jin)(jin)行(xing)(xing)(xing)逆流烘干(gan)(gan),物(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)(ceng)不(bu)(bu)(bu)斷(duan)地被反復揚進(jin)(jin),呈進(jin)(jin)兩(liang)步(bu)(bu)退一(yi)步(bu)(bu)的(de)行(xing)(xing)(xing)進(jin)(jin)方式,物(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)(ceng)既充(chong)分吸收(shou)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散(san)發的(de)熱(re)量,又(you)吸收(shou)中層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)熱(re)量,同時又(you)延長了干(gan)(gan)燥(zao)時間(jian),物(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此達到(dao)干(gan)(gan)燥(zao)狀態。物(wu)料(liao)(liao)(liao)(liao)行(xing)(xing)(xing)至中層(ceng)(ceng)(ceng)(ceng)(ceng)另一(yi)端(duan)而落入(ru)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng),物(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)呈矩形(xing)多回路方式行(xing)(xing)(xing)進(jin)(jin),達到(dao)干(gan)(gan)燥(zao)效果(guo)(guo)的(de)物(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)熱(re)風作用下快(kuai)速行(xing)(xing)(xing)進(jin)(jin)排出(chu)滾(gun)(gun)筒(tong),沒有達到(dao)干(gan)(gan)燥(zao)效果(guo)(guo)的(de)濕物(wu)料(liao)(liao)(liao)(liao)因(yin)自重而不(bu)(bu)(bu)能(neng)快(kuai)速行(xing)(xing)(xing)進(jin)(jin),物(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此矩形(xing)抄板(ban)內(nei)進(jin)(jin)行(xing)(xing)(xing)充(chong)分干(gan)(gan)燥(zao),由(you)(you)此完成干(gan)(gan)燥(zao)目的(de)。
