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。
烘干機筒體(ti)部分(fen)(fen)由三個同軸水平放置的內、中、外筒套疊(die)組成(cheng),這就使筒體(ti)的截面(mian)得到充分(fen)(fen)的利用。其筒體(ti)外形總(zong)長(chang)度約為與之相當(dang)的單(dan)筒的30-35%。從而大(da)幅度地減少占地面(mian)積(ji)和廠房建(jian)筑面(mian)積(ji)。
該機的支(zhi)承裝(zhuang)置,是在外筒上輪帶與托輪支(zhi)承,由電機直接帶動(dong)托輪。通過托輪與輪帶摩擦,使筒體轉(zhuan)動(dong)。該機總(zong)體結構緊湊、合(he)理、簡單,為便于磨損件的檢修更(geng)換,在中(zhong)間設(she)計成(cheng)軸(zhou)向剖分式(shi),用螺栓固定連接。
工(gong)作(zuo)原理(li)
物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝置進入回轉(zhuan)滾筒(tong)的(de)(de)內(nei)(nei)(nei)層(ceng)(ceng),實現(xian)順(shun)流(liu)烘(hong)干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)內(nei)(nei)(nei)層(ceng)(ceng)的(de)(de)抄(chao)板(ban)下不斷抄(chao)起(qi)、散(san)落呈(cheng)螺(luo)旋行(xing)(xing)(xing)進式實現(xian)熱交換,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移動至內(nei)(nei)(nei)層(ceng)(ceng)的(de)(de)另(ling)(ling)一(yi)端進入中層(ceng)(ceng),進行(xing)(xing)(xing)逆流(liu)烘(hong)干(gan)(gan)(gan),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)中層(ceng)(ceng)不斷地被反復揚進,呈(cheng)進兩步退一(yi)步的(de)(de)行(xing)(xing)(xing)進方式,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)中層(ceng)(ceng)既(ji)充分吸收內(nei)(nei)(nei)層(ceng)(ceng)滾筒(tong)散(san)發的(de)(de)熱量,又吸收中層(ceng)(ceng)滾筒(tong)的(de)(de)熱量,同時又延長了干(gan)(gan)(gan)燥(zao)時間,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)此(ci)達(da)(da)到(dao)干(gan)(gan)(gan)燥(zao)狀態。物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)(xing)(xing)至中層(ceng)(ceng)另(ling)(ling)一(yi)端而(er)落入外層(ceng)(ceng),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)外層(ceng)(ceng)滾筒(tong)內(nei)(nei)(nei)呈(cheng)矩(ju)(ju)形多回路方式行(xing)(xing)(xing)進,達(da)(da)到(dao)干(gan)(gan)(gan)燥(zao)效果(guo)的(de)(de)物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)熱風作用(yong)下快速行(xing)(xing)(xing)進排出滾筒(tong),沒有達(da)(da)到(dao)干(gan)(gan)(gan)燥(zao)效果(guo)的(de)(de)濕物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因自重而(er)不能快速行(xing)(xing)(xing)進,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)(zai)此(ci)矩(ju)(ju)形抄(chao)板(ban)內(nei)(nei)(nei)進行(xing)(xing)(xing)充分干(gan)(gan)(gan)燥(zao),由此(ci)完成干(gan)(gan)(gan)燥(zao)目的(de)(de)。
