產品結構
三筒式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(hong)干機筒體(ti)部分(fen)由三個(ge)同軸水平放置(zhi)的(de)(de)(de)內、中、外筒套疊組(zu)成,這就(jiu)使(shi)筒體(ti)的(de)(de)(de)截面(mian)得到充分(fen)的(de)(de)(de)利用。其筒體(ti)外形(xing)總長度約為與(yu)之相當的(de)(de)(de)單筒的(de)(de)(de)30-35%。從而大(da)幅度地減少占(zhan)地面(mian)積和(he)廠房(fang)建筑面(mian)積。
該機的支承裝置,是在外筒上輪(lun)帶與(yu)托(tuo)輪(lun)支承,由電機直接帶動托(tuo)輪(lun)。通過(guo)托(tuo)輪(lun)與(yu)輪(lun)帶摩擦,使(shi)筒體轉動。該機總體結構緊湊、合理、簡單,為便于磨損(sun)件的檢修更換,在中(zhong)間設計成(cheng)軸向(xiang)剖分式(shi),用螺(luo)栓固定(ding)連接。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)(liao)(liao)(liao)裝置(zhi)進(jin)(jin)入(ru)回轉滾(gun)筒(tong)的內(nei)(nei)(nei)層(ceng)(ceng)(ceng),實現(xian)順流烘干(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)內(nei)(nei)(nei)層(ceng)(ceng)(ceng)的抄(chao)(chao)板(ban)下不斷抄(chao)(chao)起、散落呈螺(luo)旋(xuan)行進(jin)(jin)式(shi)實現(xian)熱(re)交換(huan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)移動至內(nei)(nei)(nei)層(ceng)(ceng)(ceng)的另(ling)一(yi)(yi)端進(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)行逆流烘干(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)不斷地(di)被反復揚進(jin)(jin),呈進(jin)(jin)兩步(bu)退一(yi)(yi)步(bu)的行進(jin)(jin)方式(shi),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)既(ji)充分(fen)吸收內(nei)(nei)(nei)層(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的熱(re)量,又(you)吸收中(zhong)層(ceng)(ceng)(ceng)滾(gun)筒(tong)的熱(re)量,同時又(you)延長了干(gan)(gan)燥時間,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)此達(da)到(dao)干(gan)(gan)燥狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)行至中(zhong)層(ceng)(ceng)(ceng)另(ling)一(yi)(yi)端而落入(ru)外層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)(nei)(nei)呈矩形(xing)多回路方式(shi)行進(jin)(jin),達(da)到(dao)干(gan)(gan)燥效(xiao)果的物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)熱(re)風作用下快速(su)行進(jin)(jin)排出(chu)滾(gun)筒(tong),沒有達(da)到(dao)干(gan)(gan)燥效(xiao)果的濕物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)因自重而不能快速(su)行進(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)在(zai)此矩形(xing)抄(chao)(chao)板(ban)內(nei)(nei)(nei)進(jin)(jin)行充分(fen)干(gan)(gan)燥,由此完成干(gan)(gan)燥目的。
