產(chan)品概況
回轉式三筒烘(hong)干(gan)(gan)(gan)機(ji)(ji)改進(jin)原(yuan)單(dan)(dan)筒烘(hong)干(gan)(gan)(gan)機(ji)(ji)內部結構，增(zeng)加入機(ji)(ji)前濕料(liao)的預烘(hong)干(gan)(gan)(gan)和延長濕料(liao)在(zai)機(ji)(ji)內烘(hong)干(gan)(gan)(gan)時(shi)間，再加上密封、保溫以(yi)及合(he)理的配套措(cuo)施，使烘(hong)干(gan)(gan)(gan)機(ji)(ji)生(sheng)產(chan)能力與原(yuan)單(dan)(dan)筒式烘(hong)干(gan)(gan)(gan)機(ji)(ji)相比(bi)，提高48-80%，單(dan)(dan)位容積蒸發強度可達120-180kg/m3，標準煤(mei)耗僅為6-8kg/t。其技術(shu)先進(jin)、運行(xing)參數(shu)合(he)理，操作簡單(dan)(dan)可行(xing)，廣泛應用于各個行(xing)業(ye)的礦渣、粘土、煤(mei)。
產品結構(gou)
三(san)筒(tong)(tong)烘干機(ji)(ji)(ji)是通過對單筒(tong)(tong)烘干機(ji)(ji)(ji)的單筒(tong)(tong)體(ti)改為套疊在一起的三(san)筒(tong)(tong)，以縮短烘干機(ji)(ji)(ji)體(ti)的外(wai)形尺寸(cun)。該(gai)機(ji)(ji)(ji)工作時，物料和熱氣流(liu)依次進入內至外(wai)筒(tong)(tong)體(ti)，在機(ji)(ji)(ji)體(ti)Z形往復折流(liu)后(hou)，充分利用熱能烘干物料后(hou)再(zai)卸出。
烘干機筒(tong)體(ti)部(bu)分由三個同軸(zhou)水(shui)平(ping)放置(zhi)的內、中、外筒(tong)套疊組成，這就使筒(tong)體(ti)的截(jie)面得(de)到充(chong)分的利用。其筒(tong)體(ti)外形總(zong)長度約為(wei)與之(zhi)相當的單(dan)筒(tong)的30-35%。從而大幅度地(di)減(jian)少占地(di)面積(ji)和廠房建筑(zhu)面積(ji)。
該機的支(zhi)承裝置，是在(zai)外筒(tong)上輪(lun)帶(dai)與托輪(lun)支(zhi)承，由(you)電機直(zhi)接(jie)帶(dai)動(dong)托輪(lun)。通過托輪(lun)與輪(lun)帶(dai)摩(mo)擦，使筒(tong)體轉動(dong)。該機總體結(jie)構緊湊、合理、簡單，為便于磨(mo)損件的檢修更換，在(zai)中間設計(ji)成軸向剖分式，用螺栓(shuan)固定連接(jie)。
工作原理
