氣力(li)輸送(song)原理

氣(qi)(qi)(qi)力輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)系統可分類(lei)為(wei)不同的(de)(de)(de)(de)流(liu)動(dong)(dong)型(xing)式(shi),其中(zhong)兩(liang)種主要(yao)型(xing)式(shi)是:(a) 稀(xi)相(xiang)(xiang)(xiang)(xiang)(xiang)輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)和(b)密(mi)(mi)相(xiang)(xiang)(xiang)(xiang)(xiang)輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)每種流(liu)動(dong)(dong)型(xing)式(shi)可按物(wu)料(liao)(liao)與空(kong)氣(qi)(qi)(qi)的(de)(de)(de)(de)流(liu)量(liang)比(bi)(bi)率大小分類(lei),其比(bi)(bi)率也(ye)被(bei)(bei)稱為(wei)“固(gu)氣(qi)(qi)(qi)比(bi)(bi)”: μ=ms/mf (1)許(xu)多稀(xi)相(xiang)(xiang)(xiang)(xiang)(xiang)的(de)(de)(de)(de)運行范圍為(wei)0<μ<15,而(er)密(mi)(mi)相(xiang)(xiang)(xiang)(xiang)(xiang)通(tong)(tong)常(chang)是μ>15。圖(tu)1所示的(de)(de)(de)(de)是典(dian)型(xing)輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)狀態(tai)圖(tu)。稀(xi)相(xiang)(xiang)(xiang)(xiang)(xiang)輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)可以被(bei)(bei)認(ren)為(wei)是一(yi)(yi)種完全(quan)的(de)(de)(de)(de)懸浮流(liu),而(er)密(mi)(mi)相(xiang)(xiang)(xiang)(xiang)(xiang)輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)通(tong)(tong)常(chang)被(bei)(bei)認(ren)為(wei)是非(fei)懸浮流(liu)。然而(er),如圖(tu)1所示,許(xu)多不同種類(lei)的(de)(de)(de)(de)密(mi)(mi)相(xiang)(xiang)(xiang)(xiang)(xiang)(非(fei)懸浮流(liu))依(yi)靠(kao)散料(liao)(liao)的(de)(de)(de)(de)料(liao)(liao)性(xing)和流(liu)動(dong)(dong)性(xing)存在(zai)。密(mi)(mi)相(xiang)(xiang)(xiang)(xiang)(xiang)輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)同樣也(ye)能(neng)被(bei)(bei)定義為(wei)輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)物(wu)料(liao)(liao)完全(quan)填(tian)滿管(guan)道截(jie)面(mian)(mian)的(de)(de)(de)(de)一(yi)(yi)種輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)方式(shi)。稀(xi)相(xiang)(xiang)(xiang)(xiang)(xiang)輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)通(tong)(tong)常(chang)需(xu)要(yao)使用大量(liang)的(de)(de)(de)(de)高(gao)速(su)氣(qi)(qi)(qi)體。氣(qi)(qi)(qi)流(liu)依(yi)靠(kao)升力和推(tui)動(dong)(dong)力以離散粒子的(de)(de)(de)(de)形式(shi)攜帶著物(wu)料(liao)(liao)。參考圖(tu)1中(zhong)所述的(de)(de)(de)(de)“懸浮流(liu)”,稀(xi)相(xiang)(xiang)(xiang)(xiang)(xiang)系統通(tong)(tong)常(chang)是最為(wei)被(bei)(bei)廣(guang)泛應用的(de)(de)(de)(de)氣(qi)(qi)(qi)力輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)系統。由于稀(xi)相(xiang)(xiang)(xiang)(xiang)(xiang)系統設計(ji)的(de)(de)(de)(de)相(xiang)(xiang)(xiang)(xiang)(xiang)對(dui)簡單性(xing),它們同時(shi)也(ye)被(bei)(bei)頻(pin)繁的(de)(de)(de)(de)應用在(zai)工業領(ling)域。輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)氣(qi)(qi)(qi)體的(de)(de)(de)(de)速(su)度(du)(du)減少到比(bi)(bi)保持粒子懸浮狀態(tai)的(de)(de)(de)(de)臨(lin)界(jie)值更(geng)小時(shi),導致物(wu)料(liao)(liao)在(zai)輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)管(guan)道的(de)(de)(de)(de)橫截(jie)面(mian)(mian)形成不均勻(yun)的(de)(de)(de)(de)分布。臨(lin)界(jie)氣(qi)(qi)(qi)體速(su)度(du)(du)被(bei)(bei)稱為(wei)是水平(ping)輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)的(de)(de)(de)(de)跳(tiao)躍速(su)度(du)(du),垂直輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)時(shi)堵塞。當水平(ping)管(guan)道中(zhong)的(de)(de)(de)(de)物(wu)料(liao)(liao)表面(mian)(mian)氣(qi)(qi)(qi)體速(su)度(du)(du)低于突變速(su)度(du)(du)時(shi),輸(shu)(shu)(shu)(shu)(shu)(shu)送(song)(song)將(jiang)會(hui)以低流(liu)量(liang)通(tong)(tong)過管(guan)道橫截(jie)面(mian)(mian)的(de)(de)(de)(de)上(shang)部(bu)(bu),在(zai)管(guan)道的(de)(de)(de)(de)剩(sheng)余部(bu)(bu)分以高(gao)濃度(du)(du)低速(su)度(du)(du)的(de)(de)(de)(de)形式(shi)填(tian)充。有時(shi)沿管(guan)道的(de)(de)(de)(de)橫截(jie)面(mian)(mian)會(hui)被(bei)(bei)填(tian)滿,而(er)有時(shi)只是部(bu)(bu)分被(bei)(bei)填(tian)滿.


實(shi)際(ji)應用(yong)中, 按(an)照氣力驅動形式可(ke)(ke)以分(fen)為負(fu)壓和正壓氣力輸(shu)送(song), 在這兩種輸(shu)送(song)系統中, 根據流(liu)(liu)動狀態(tai)圖再區分(fen)分(fen)為稀相, 密相和流(liu)(liu)化(hua)態(tai)輸(shu)送(song)系統. 除(chu)此之外,根據喂料不同分(fen)為連續和批次(ci)輸(shu)送(song). 在高(gao)壓密相輸(shu)送(song)技術中常采用(yong)批次(ci)的壓力罐進(jin)行高(gao)壓輸(shu)送(song), 同時, 可(ke)(ke)以組合兩個(ge)壓力罐設計達到連續的輸(shu)送(song).


密(mi)相氣力輸送特點:

● 用氣量(liang)小, 節能(neng)

● 無殘留輸(shu)送(song)

● 不堵塞, 運行可靠

● 維護(hu)費用低

● 適(shi)合于各類粉粒物料(liao)

● 壓力至0. 6m p a可調

● 適合于柔(rou)性化自動生產(chan)中的物(wu)料高效(xiao)輸送(song)
