產品結構
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(gan)機筒(tong)體(ti)部分(fen)由(you)三個同軸(zhou)水平放置的(de)內(nei)、中(zhong)、外(wai)筒(tong)套疊組成,這就使筒(tong)體(ti)的(de)截面(mian)得到充分(fen)的(de)利用(yong)。其筒(tong)體(ti)外(wai)形(xing)總(zong)長度(du)約為與之(zhi)相當的(de)單筒(tong)的(de)30-35%。從而(er)大幅(fu)度(du)地減(jian)少(shao)占(zhan)地面(mian)積和廠房建筑面(mian)積。
該(gai)(gai)機(ji)的支(zhi)承裝置,是在(zai)外筒上(shang)輪帶(dai)與托輪支(zhi)承,由電(dian)機(ji)直(zhi)接帶(dai)動(dong)托輪。通過(guo)托輪與輪帶(dai)摩擦,使筒體(ti)轉動(dong)。該(gai)(gai)機(ji)總體(ti)結構緊湊(cou)、合理、簡單,為便(bian)于磨損件(jian)的檢修更換,在(zai)中間設計成軸(zhou)向剖分式,用(yong)螺栓(shuan)固定連接。
工作原理
物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)(liao)裝置進(jin)(jin)入(ru)回轉滾筒(tong)(tong)的(de)內(nei)層(ceng),實(shi)現(xian)順流烘干,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)的(de)抄(chao)(chao)(chao)板下不(bu)斷抄(chao)(chao)(chao)起、散(san)落呈(cheng)(cheng)(cheng)螺旋(xuan)行(xing)進(jin)(jin)式實(shi)現(xian)熱(re)(re)交換,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)移(yi)動至內(nei)層(ceng)的(de)另一端(duan)進(jin)(jin)入(ru)中(zhong)層(ceng),進(jin)(jin)行(xing)逆(ni)流烘干,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)不(bu)斷地被(bei)反復揚進(jin)(jin),呈(cheng)(cheng)(cheng)進(jin)(jin)兩步退一步的(de)行(xing)進(jin)(jin)方(fang)式,物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)既充分(fen)吸收內(nei)層(ceng)滾筒(tong)(tong)散(san)發(fa)的(de)熱(re)(re)量(liang)(liang),又吸收中(zhong)層(ceng)滾筒(tong)(tong)的(de)熱(re)(re)量(liang)(liang),同時(shi)又延長了干燥(zao)時(shi)間(jian),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)此達到(dao)(dao)干燥(zao)狀態。物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)行(xing)至中(zhong)層(ceng)另一端(duan)而落入(ru)外(wai)(wai)層(ceng),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)外(wai)(wai)層(ceng)滾筒(tong)(tong)內(nei)呈(cheng)(cheng)(cheng)矩(ju)形多回路方(fang)式行(xing)進(jin)(jin),達到(dao)(dao)干燥(zao)效果(guo)的(de)物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)熱(re)(re)風作用下快速行(xing)進(jin)(jin)排出滾筒(tong)(tong),沒(mei)有達到(dao)(dao)干燥(zao)效果(guo)的(de)濕物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)因自重而不(bu)能快速行(xing)進(jin)(jin),物(wu)(wu)(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)此矩(ju)形抄(chao)(chao)(chao)板內(nei)進(jin)(jin)行(xing)充分(fen)干燥(zao),由此完成干燥(zao)目的(de)。
