產(chan)品(pin)概況
回(hui)轉式三筒(tong)(tong)烘(hong)(hong)(hong)干(gan)(gan)機(ji)(ji)(ji)改進原(yuan)單(dan)筒(tong)(tong)烘(hong)(hong)(hong)干(gan)(gan)機(ji)(ji)(ji)內部結構，增加(jia)入(ru)機(ji)(ji)(ji)前濕料的預烘(hong)(hong)(hong)干(gan)(gan)和延(yan)長濕料在機(ji)(ji)(ji)內烘(hong)(hong)(hong)干(gan)(gan)時間，再加(jia)上密封、保(bao)溫以(yi)及合理的配套措施，使烘(hong)(hong)(hong)干(gan)(gan)機(ji)(ji)(ji)生(sheng)產能力與(yu)原(yuan)單(dan)筒(tong)(tong)式烘(hong)(hong)(hong)干(gan)(gan)機(ji)(ji)(ji)相比，提高(gao)48-80%，單(dan)位容積蒸發(fa)強度可達120-180kg/m3，標準煤耗僅為6-8kg/t。其(qi)技術先進、運行(xing)參(can)數合理，操作簡單(dan)可行(xing)，廣泛應用于(yu)各個行(xing)業的礦渣、粘(zhan)土、煤。
產品結構
三(san)筒(tong)烘干機(ji)是通過對單筒(tong)烘干機(ji)的單筒(tong)體(ti)改(gai)為套疊(die)在一起的三(san)筒(tong)，以(yi)縮短烘干機(ji)體(ti)的外(wai)形尺(chi)寸。該機(ji)工作時，物(wu)料和熱氣流依次進入內至外(wai)筒(tong)體(ti)，在機(ji)體(ti)Z形往復折流后，充分利用熱能烘干物(wu)料后再卸出。
烘干機筒(tong)體(ti)部分由(you)三個同軸水平放置的(de)內、中、外(wai)筒(tong)套疊組成，這就(jiu)使筒(tong)體(ti)的(de)截面(mian)得到充(chong)分的(de)利用(yong)。其筒(tong)體(ti)外(wai)形(xing)總長(chang)度(du)約為(wei)與之(zhi)相當的(de)單(dan)筒(tong)的(de)30-35%。從而大幅度(du)地(di)減(jian)少占地(di)面(mian)積和廠房建筑(zhu)面(mian)積。
該(gai)機的(de)支(zhi)承裝置(zhi)，是在外(wai)筒(tong)(tong)上輪帶(dai)與托(tuo)輪支(zhi)承，由電機直(zhi)接帶(dai)動托(tuo)輪。通過托(tuo)輪與輪帶(dai)摩擦，使筒(tong)(tong)體(ti)轉動。該(gai)機總體(ti)結構緊湊、合(he)理、簡單，為便于磨(mo)損件(jian)的(de)檢修更(geng)換，在中間(jian)設計成軸(zhou)向剖分式，用螺栓(shuan)固定連接。
工作原理
物(wu)(wu)料(liao)由(you)供料(liao)裝(zhuang)置進(jin)入(ru)(ru)回轉(zhuan)滾(gun)筒(tong)的(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實現順流(liu)烘干(gan)(gan)(gan),物(wu)(wu)料(liao)在內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄(chao)板(ban)下不(bu)斷抄(chao)起、散落呈螺(luo)旋行進(jin)式(shi)(shi)實現熱交換(huan)，物(wu)(wu)料(liao)移動(dong)至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)另一(yi)(yi)端進(jin)入(ru)(ru)中(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)行逆流(liu)烘干(gan)(gan)(gan)，物(wu)(wu)料(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷地被反復(fu)揚進(jin)，呈進(jin)兩(liang)步(bu)退(tui)一(yi)(yi)步(bu)的(de)(de)行進(jin)方式(shi)(shi)，物(wu)(wu)料(liao)在中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸(xi)收(shou)內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的(de)(de)熱量，又吸(xi)收(shou)中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)(de)熱量，同時又延長了干(gan)(gan)(gan)燥(zao)時間，物(wu)(wu)料(liao)在此達到干(gan)(gan)(gan)燥(zao)狀態。物(wu)(wu)料(liao)行至中(zhong)層(ceng)(ceng)(ceng)(ceng)另一(yi)(yi)端而(er)落入(ru)(ru)外層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)料(liao)在外層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)呈矩(ju)形多(duo)回路方式(shi)(shi)行進(jin)，達到干(gan)(gan)(gan)燥(zao)效果的(de)(de)物(wu)(wu)料(liao)在熱風(feng)作用下快速行進(jin)排出滾(gun)筒(tong)，沒有(you)達到干(gan)(gan)(gan)燥(zao)效果的(de)(de)濕物(wu)(wu)料(liao)因(yin)自(zi)重而(er)不(bu)能快速行進(jin)，物(wu)(wu)料(liao)在此矩(ju)形抄(chao)板(ban)內(nei)進(jin)行充分干(gan)(gan)(gan)燥(zao)，由(you)此完成干(gan)(gan)(gan)燥(zao)目(mu)的(de)(de)。
