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)(tong)(tong)體部分由三個同軸水平放(fang)置的(de)內(nei)、中、外(wai)筒(tong)(tong)(tong)套疊(die)組成,這就使(shi)筒(tong)(tong)(tong)體的(de)截面得(de)到充分的(de)利(li)用。其筒(tong)(tong)(tong)體外(wai)形總長度約(yue)為與之相當的(de)單筒(tong)(tong)(tong)的(de)30-35%。從(cong)而大幅度地(di)減少占(zhan)地(di)面積和廠(chang)房(fang)建筑面積。
該機(ji)的(de)支(zhi)承裝置,是(shi)在外(wai)筒(tong)上(shang)輪(lun)(lun)帶與(yu)托(tuo)輪(lun)(lun)支(zhi)承,由電(dian)機(ji)直接帶動(dong)托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與(yu)輪(lun)(lun)帶摩擦,使筒(tong)體轉動(dong)。該機(ji)總體結構緊湊、合理、簡單(dan),為(wei)便于磨(mo)損件的(de)檢修更換,在中間設計成軸向剖分式,用螺(luo)栓固定(ding)連接。
工作原理
物(wu)(wu)料(liao)(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)(liao)裝置進(jin)入(ru)回轉滾筒(tong)的(de)(de)(de)內(nei)層(ceng),實現(xian)順流烘干(gan),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)內(nei)層(ceng)的(de)(de)(de)抄(chao)板(ban)(ban)下不(bu)斷抄(chao)起、散落呈(cheng)螺(luo)旋行(xing)進(jin)式(shi)實現(xian)熱(re)交換,物(wu)(wu)料(liao)(liao)(liao)(liao)移動至內(nei)層(ceng)的(de)(de)(de)另一端進(jin)入(ru)中(zhong)層(ceng),進(jin)行(xing)逆(ni)流烘干(gan),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)中(zhong)層(ceng)不(bu)斷地被反(fan)復(fu)揚進(jin),呈(cheng)進(jin)兩(liang)步退(tui)一步的(de)(de)(de)行(xing)進(jin)方式(shi),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)中(zhong)層(ceng)既充分(fen)吸收(shou)內(nei)層(ceng)滾筒(tong)散發的(de)(de)(de)熱(re)量,又吸收(shou)中(zhong)層(ceng)滾筒(tong)的(de)(de)(de)熱(re)量,同(tong)時(shi)又延長了(le)干(gan)燥(zao)時(shi)間(jian),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)此(ci)達到干(gan)燥(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)至中(zhong)層(ceng)另一端而落入(ru)外(wai)層(ceng),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)外(wai)層(ceng)滾筒(tong)內(nei)呈(cheng)矩形(xing)多(duo)回路方式(shi)行(xing)進(jin),達到干(gan)燥(zao)效果的(de)(de)(de)物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)熱(re)風(feng)作(zuo)用下快速行(xing)進(jin)排出(chu)滾筒(tong),沒有達到干(gan)燥(zao)效果的(de)(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)(liao)因自重而不(bu)能快速行(xing)進(jin),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)此(ci)矩形(xing)抄(chao)板(ban)(ban)內(nei)進(jin)行(xing)充分(fen)干(gan)燥(zao),由此(ci)完成(cheng)干(gan)燥(zao)目的(de)(de)(de)。
