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。
烘干機筒體部(bu)分由(you)三個同軸水平(ping)放置的內、中、外筒套(tao)疊(die)組成,這就使(shi)筒體的截面得到充分的利用。其(qi)筒體外形總(zong)長(chang)度(du)約(yue)為(wei)與之相當的單筒的30-35%。從而(er)大幅度(du)地減(jian)少占地面積和廠房建筑面積。
該機(ji)的支(zhi)承(cheng)裝置,是(shi)在外(wai)筒上輪(lun)(lun)帶(dai)與(yu)(yu)托輪(lun)(lun)支(zhi)承(cheng),由電機(ji)直(zhi)接(jie)帶(dai)動(dong)托輪(lun)(lun)。通(tong)過托輪(lun)(lun)與(yu)(yu)輪(lun)(lun)帶(dai)摩擦,使筒體轉動(dong)。該機(ji)總(zong)體結構緊湊、合(he)理、簡(jian)單(dan),為便(bian)于(yu)磨損件的檢(jian)修更換,在中間設計(ji)成軸向剖分式(shi),用螺栓固定連接(jie)。
工作原理
物(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)(jin)入回轉滾(gun)筒(tong)的(de)內(nei)層(ceng)(ceng)(ceng),實現(xian)順(shun)流(liu)烘干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)層(ceng)(ceng)(ceng)的(de)抄(chao)板下不斷抄(chao)起(qi)、散落呈(cheng)螺旋行(xing)進(jin)(jin)(jin)(jin)式實現(xian)熱(re)(re)(re)交換,物(wu)(wu)(wu)料(liao)(liao)移動至(zhi)內(nei)層(ceng)(ceng)(ceng)的(de)另(ling)一端進(jin)(jin)(jin)(jin)入中層(ceng)(ceng)(ceng),進(jin)(jin)(jin)(jin)行(xing)逆流(liu)烘干(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)不斷地被反(fan)復揚(yang)進(jin)(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)(jin)兩步退(tui)一步的(de)行(xing)進(jin)(jin)(jin)(jin)方式,物(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)既充(chong)分(fen)吸收(shou)內(nei)層(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的(de)熱(re)(re)(re)量,又吸收(shou)中層(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)熱(re)(re)(re)量,同(tong)時又延長了干(gan)(gan)燥(zao)(zao)時間(jian),物(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)達(da)到(dao)干(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)行(xing)至(zhi)中層(ceng)(ceng)(ceng)另(ling)一端而落入外(wai)層(ceng)(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)呈(cheng)矩(ju)(ju)形多(duo)回路方式行(xing)進(jin)(jin)(jin)(jin),達(da)到(dao)干(gan)(gan)燥(zao)(zao)效果的(de)物(wu)(wu)(wu)料(liao)(liao)在(zai)熱(re)(re)(re)風作用下快速行(xing)進(jin)(jin)(jin)(jin)排出滾(gun)筒(tong),沒有達(da)到(dao)干(gan)(gan)燥(zao)(zao)效果的(de)濕物(wu)(wu)(wu)料(liao)(liao)因自重而不能快速行(xing)進(jin)(jin)(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)矩(ju)(ju)形抄(chao)板內(nei)進(jin)(jin)(jin)(jin)行(xing)充(chong)分(fen)干(gan)(gan)燥(zao)(zao),由此(ci)完(wan)成干(gan)(gan)燥(zao)(zao)目的(de)。
