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。
烘干機筒(tong)(tong)(tong)體(ti)部分由三個同軸水平放置的內(nei)、中、外筒(tong)(tong)(tong)套疊組成,這就使筒(tong)(tong)(tong)體(ti)的截面得到充分的利用(yong)。其筒(tong)(tong)(tong)體(ti)外形(xing)總長(chang)度約為與之相當(dang)的單筒(tong)(tong)(tong)的30-35%。從而(er)大幅度地減少占地面積(ji)和(he)廠房(fang)建(jian)筑面積(ji)。
該機(ji)的支承裝置,是(shi)在外筒上輪(lun)帶(dai)與(yu)托(tuo)輪(lun)支承,由電機(ji)直接(jie)帶(dai)動托(tuo)輪(lun)。通過(guo)托(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩擦,使筒體(ti)(ti)轉(zhuan)動。該機(ji)總體(ti)(ti)結構(gou)緊湊、合理(li)、簡單,為便(bian)于磨損件的檢(jian)修更換,在中(zhong)間(jian)設計成軸向剖分式,用螺栓固定連接(jie)。
工作原理
物(wu)(wu)料(liao)(liao)(liao)(liao)由(you)供(gong)料(liao)(liao)(liao)(liao)裝置進(jin)(jin)入回轉滾(gun)筒(tong)的(de)(de)內層(ceng)(ceng),實現(xian)順流烘干,物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)內層(ceng)(ceng)的(de)(de)抄(chao)板下不斷抄(chao)起、散落(luo)呈(cheng)螺旋行進(jin)(jin)式實現(xian)熱(re)(re)交換,物(wu)(wu)料(liao)(liao)(liao)(liao)移動至內層(ceng)(ceng)的(de)(de)另(ling)一端進(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng),進(jin)(jin)行逆流烘干,物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)不斷地被反復揚進(jin)(jin),呈(cheng)進(jin)(jin)兩步退一步的(de)(de)行進(jin)(jin)方式,物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)既充分吸(xi)收內層(ceng)(ceng)滾(gun)筒(tong)散發的(de)(de)熱(re)(re)量,又(you)吸(xi)收中(zhong)(zhong)層(ceng)(ceng)滾(gun)筒(tong)的(de)(de)熱(re)(re)量,同時(shi)又(you)延長(chang)了干燥(zao)(zao)(zao)(zao)時(shi)間,物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)此達(da)到干燥(zao)(zao)(zao)(zao)狀態(tai)。物(wu)(wu)料(liao)(liao)(liao)(liao)行至中(zhong)(zhong)層(ceng)(ceng)另(ling)一端而落(luo)入外(wai)層(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)外(wai)層(ceng)(ceng)滾(gun)筒(tong)內呈(cheng)矩(ju)形多回路方式行進(jin)(jin),達(da)到干燥(zao)(zao)(zao)(zao)效果的(de)(de)物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)熱(re)(re)風作用下快(kuai)速(su)行進(jin)(jin)排出滾(gun)筒(tong),沒有達(da)到干燥(zao)(zao)(zao)(zao)效果的(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)(liao)因自重而不能(neng)快(kuai)速(su)行進(jin)(jin),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)此矩(ju)形抄(chao)板內進(jin)(jin)行充分干燥(zao)(zao)(zao)(zao),由(you)此完(wan)成干燥(zao)(zao)(zao)(zao)目的(de)(de)。
