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(hong)干機(ji)筒(tong)體(ti)部分由三個同軸水平放(fang)置的內、中、外筒(tong)套疊(die)組(zu)成,這就使(shi)筒(tong)體(ti)的截(jie)面(mian)得到充分的利用。其筒(tong)體(ti)外形(xing)總長(chang)度約為與之相當的單(dan)筒(tong)的30-35%。從而(er)大幅度地減少(shao)占(zhan)地面(mian)積(ji)和(he)廠(chang)房建筑面(mian)積(ji)。
該機的(de)(de)支(zhi)(zhi)承裝置,是在外筒(tong)上輪(lun)(lun)(lun)帶(dai)與托輪(lun)(lun)(lun)支(zhi)(zhi)承,由電機直接帶(dai)動(dong)托輪(lun)(lun)(lun)。通過托輪(lun)(lun)(lun)與輪(lun)(lun)(lun)帶(dai)摩擦,使筒(tong)體轉動(dong)。該機總體結構緊湊、合理(li)、簡單,為便于(yu)磨損(sun)件的(de)(de)檢修更換(huan),在中(zhong)間設計(ji)成軸向剖(pou)分式(shi),用(yong)螺栓固定連接。
工作原理
物料(liao)(liao)(liao)由供(gong)料(liao)(liao)(liao)裝置進(jin)(jin)入回轉滾筒(tong)(tong)的(de)(de)(de)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng),實現順(shun)流烘(hong)干(gan)(gan),物料(liao)(liao)(liao)在(zai)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)板(ban)下不斷(duan)抄(chao)起、散(san)落呈(cheng)螺旋行(xing)(xing)進(jin)(jin)式實現熱(re)(re)交換,物料(liao)(liao)(liao)移(yi)動至內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另(ling)一(yi)端(duan)進(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)行(xing)(xing)逆流烘(hong)干(gan)(gan),物料(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)不斷(duan)地(di)被(bei)反(fan)復揚進(jin)(jin),呈(cheng)進(jin)(jin)兩步(bu)退一(yi)步(bu)的(de)(de)(de)行(xing)(xing)進(jin)(jin)方式,物料(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)既充(chong)分(fen)吸收(shou)內(nei)(nei)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)散(san)發的(de)(de)(de)熱(re)(re)量,又(you)吸收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)的(de)(de)(de)熱(re)(re)量,同時又(you)延長了(le)干(gan)(gan)燥(zao)時間(jian),物料(liao)(liao)(liao)在(zai)此(ci)達(da)到干(gan)(gan)燥(zao)狀態(tai)。物料(liao)(liao)(liao)行(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一(yi)端(duan)而(er)落入外層(ceng)(ceng)(ceng)(ceng),物料(liao)(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)(ceng)滾筒(tong)(tong)內(nei)(nei)呈(cheng)矩形多回路方式行(xing)(xing)進(jin)(jin),達(da)到干(gan)(gan)燥(zao)效果的(de)(de)(de)物料(liao)(liao)(liao)在(zai)熱(re)(re)風作(zuo)用下快(kuai)速(su)行(xing)(xing)進(jin)(jin)排出滾筒(tong)(tong),沒有達(da)到干(gan)(gan)燥(zao)效果的(de)(de)(de)濕物料(liao)(liao)(liao)因(yin)自(zi)重而(er)不能快(kuai)速(su)行(xing)(xing)進(jin)(jin),物料(liao)(liao)(liao)在(zai)此(ci)矩形抄(chao)板(ban)內(nei)(nei)進(jin)(jin)行(xing)(xing)充(chong)分(fen)干(gan)(gan)燥(zao),由此(ci)完成干(gan)(gan)燥(zao)目的(de)(de)(de)。
