產品概況
回轉式三筒(tong)(tong)烘(hong)(hong)干(gan)(gan)機(ji)改(gai)進原(yuan)單筒(tong)(tong)烘(hong)(hong)干(gan)(gan)機(ji)內部(bu)結構，增(zeng)加入機(ji)前濕(shi)料的預烘(hong)(hong)干(gan)(gan)和延長(chang)濕(shi)料在機(ji)內烘(hong)(hong)干(gan)(gan)時(shi)間，再(zai)加上密封、保溫以(yi)及(ji)合理的配套措施(shi)，使烘(hong)(hong)干(gan)(gan)機(ji)生產能力與原(yuan)單筒(tong)(tong)式烘(hong)(hong)干(gan)(gan)機(ji)相比，提(ti)高48-80%，單位容積蒸發強度可(ke)達120-180kg/m3，標(biao)準(zhun)煤耗僅為(wei)6-8kg/t。其技術(shu)先進、運(yun)行參數合理，操作簡單可(ke)行，廣泛應(ying)用于各(ge)個行業的礦(kuang)渣、粘土、煤。
產品(pin)結(jie)構
三(san)筒烘(hong)干機(ji)是通過對單(dan)筒烘(hong)干機(ji)的單(dan)筒體改為套疊在一(yi)起(qi)的三(san)筒，以(yi)縮短烘(hong)干機(ji)體的外(wai)形(xing)尺寸。該機(ji)工作時(shi)，物料(liao)和熱氣(qi)流(liu)依次(ci)進入內(nei)至(zhi)外(wai)筒體，在機(ji)體Z形(xing)往(wang)復折流(liu)后，充分利(li)用熱能烘(hong)干物料(liao)后再卸出。
烘干機(ji)筒(tong)體部分由三個同軸水平(ping)放置(zhi)的內、中、外筒(tong)套(tao)疊組成，這就使筒(tong)體的截面(mian)得到充分的利用。其(qi)筒(tong)體外形總長度約為(wei)與(yu)之相當的單筒(tong)的30-35%。從(cong)而大(da)幅(fu)度地減少占地面(mian)積和廠房建筑面(mian)積。
該(gai)機的支(zhi)承裝置，是在外筒上輪(lun)帶(dai)與(yu)(yu)托(tuo)輪(lun)支(zhi)承，由(you)電機直(zhi)接帶(dai)動托(tuo)輪(lun)。通(tong)過(guo)托(tuo)輪(lun)與(yu)(yu)輪(lun)帶(dai)摩擦(ca)，使筒體轉動。該(gai)機總體結構緊湊、合理、簡(jian)單，為便于磨損件(jian)的檢修(xiu)更換，在中間設計(ji)成軸向剖分式，用螺栓固(gu)定連接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)由供(gong)料(liao)(liao)裝置進(jin)(jin)入(ru)回轉(zhuan)滾(gun)筒的(de)內(nei)(nei)層(ceng),實現(xian)順流烘干,物(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)(nei)層(ceng)的(de)抄(chao)板下(xia)不(bu)斷抄(chao)起、散落(luo)呈螺旋行(xing)(xing)進(jin)(jin)式(shi)實現(xian)熱(re)交(jiao)換，物(wu)(wu)(wu)料(liao)(liao)移動至(zhi)內(nei)(nei)層(ceng)的(de)另(ling)一端進(jin)(jin)入(ru)中(zhong)(zhong)層(ceng)，進(jin)(jin)行(xing)(xing)逆流烘干，物(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)不(bu)斷地被反復(fu)揚進(jin)(jin)，呈進(jin)(jin)兩步(bu)退一步(bu)的(de)行(xing)(xing)進(jin)(jin)方式(shi)，物(wu)(wu)(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)既充分吸收(shou)內(nei)(nei)層(ceng)滾(gun)筒散發的(de)熱(re)量(liang)，又(you)吸收(shou)中(zhong)(zhong)層(ceng)滾(gun)筒的(de)熱(re)量(liang)，同時(shi)又(you)延長了干燥(zao)(zao)(zao)時(shi)間(jian)，物(wu)(wu)(wu)料(liao)(liao)在(zai)此達到干燥(zao)(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)至(zhi)中(zhong)(zhong)層(ceng)另(ling)一端而落(luo)入(ru)外層(ceng)，物(wu)(wu)(wu)料(liao)(liao)在(zai)外層(ceng)滾(gun)筒內(nei)(nei)呈矩(ju)形(xing)多回路方式(shi)行(xing)(xing)進(jin)(jin)，達到干燥(zao)(zao)(zao)效(xiao)果(guo)的(de)物(wu)(wu)(wu)料(liao)(liao)在(zai)熱(re)風作用(yong)下(xia)快速行(xing)(xing)進(jin)(jin)排出(chu)滾(gun)筒，沒有達到干燥(zao)(zao)(zao)效(xiao)果(guo)的(de)濕物(wu)(wu)(wu)料(liao)(liao)因自重而不(bu)能快速行(xing)(xing)進(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)在(zai)此矩(ju)形(xing)抄(chao)板內(nei)(nei)進(jin)(jin)行(xing)(xing)充分干燥(zao)(zao)(zao)，由此完成干燥(zao)(zao)(zao)目的(de)。
