產品結(jie)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。
烘干機筒(tong)體部(bu)分由三(san)個同軸水平放(fang)置的(de)內、中、外筒(tong)套(tao)疊組成,這就使筒(tong)體的(de)截面得(de)到充分的(de)利(li)用(yong)。其筒(tong)體外形總長(chang)度約(yue)為(wei)與(yu)之相當的(de)單(dan)筒(tong)的(de)30-35%。從而大幅度地減少(shao)占地面積和廠房建筑面積。
該機的支承裝置,是在外(wai)筒上輪(lun)(lun)帶(dai)與(yu)托(tuo)輪(lun)(lun)支承,由電(dian)機直接帶(dai)動(dong)(dong)托(tuo)輪(lun)(lun)。通(tong)過托(tuo)輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)摩擦,使筒體轉(zhuan)動(dong)(dong)。該機總體結構緊(jin)湊(cou)、合理(li)、簡單,為便于磨損(sun)件(jian)的檢修更換(huan),在中間(jian)設計成軸向(xiang)剖(pou)分式,用螺栓(shuan)固定連接。
工作(zuo)原理(li)
物(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置(zhi)進(jin)(jin)入回(hui)轉滾(gun)筒(tong)的(de)內層(ceng)(ceng)(ceng),實(shi)現順流(liu)烘干(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)在內層(ceng)(ceng)(ceng)的(de)抄(chao)板下(xia)不斷(duan)抄(chao)起(qi)、散落(luo)呈螺(luo)旋行(xing)(xing)(xing)進(jin)(jin)式(shi)實(shi)現熱(re)交換(huan),物(wu)(wu)料(liao)(liao)(liao)移(yi)動至內層(ceng)(ceng)(ceng)的(de)另(ling)(ling)一(yi)端進(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)行(xing)(xing)(xing)逆流(liu)烘干(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)(ceng)不斷(duan)地被反復揚(yang)進(jin)(jin),呈進(jin)(jin)兩步(bu)退一(yi)步(bu)的(de)行(xing)(xing)(xing)進(jin)(jin)方式(shi),物(wu)(wu)料(liao)(liao)(liao)在中(zhong)(zhong)層(ceng)(ceng)(ceng)既充分吸(xi)收(shou)(shou)內層(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的(de)熱(re)量(liang),又吸(xi)收(shou)(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)熱(re)量(liang),同時又延長了干(gan)(gan)燥(zao)時間,物(wu)(wu)料(liao)(liao)(liao)在此達到干(gan)(gan)燥(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)另(ling)(ling)一(yi)端而落(luo)入外層(ceng)(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)在外層(ceng)(ceng)(ceng)滾(gun)筒(tong)內呈矩形(xing)多回(hui)路(lu)方式(shi)行(xing)(xing)(xing)進(jin)(jin),達到干(gan)(gan)燥(zao)效果的(de)物(wu)(wu)料(liao)(liao)(liao)在熱(re)風作用下(xia)快(kuai)速行(xing)(xing)(xing)進(jin)(jin)排出滾(gun)筒(tong),沒(mei)有達到干(gan)(gan)燥(zao)效果的(de)濕物(wu)(wu)料(liao)(liao)(liao)因自(zi)重而不能快(kuai)速行(xing)(xing)(xing)進(jin)(jin),物(wu)(wu)料(liao)(liao)(liao)在此矩形(xing)抄(chao)板內進(jin)(jin)行(xing)(xing)(xing)充分干(gan)(gan)燥(zao),由此完成干(gan)(gan)燥(zao)目的(de)。
