慣性振動篩與共振篩在工作原理上有何區別?_已解決 : 慣性共振篩的工作原理:是利用連桿上裝有彈簧的曲柄連桿機構驅動,使篩子在共振狀態下進行篩分。工作原理是當共振篩的篩箱壓縮彈簧而運動時,其運動速度和動能都逐漸減小,被壓縮的彈簧所儲存的位能卻逐

慣性振動篩與共振篩在工作原理上有何區別?_已解決 : 慣性共振(zhen)(zhen)篩(shai)(shai)的(de)(de)(de)工(gong)作(zuo)原理:是(shi)利(li)用連桿(gan)上裝有彈(dan)簧(huang)的(de)(de)(de)曲柄連桿(gan)機構驅動(dong),使篩(shai)(shai)子在共振(zhen)(zhen)狀態(tai)下進行篩(shai)(shai)分。工(gong)作(zuo)原理是(shi)當共振(zhen)(zhen)篩(shai)(shai)的(de)(de)(de)篩(shai)(shai)箱(xiang)壓縮彈(dan)簧(huang)而運動(dong)時,其(qi)運動(dong)速(su)度和動(dong)能(neng)都逐漸減小(xiao)(xiao),被壓縮的(de)(de)(de)彈(dan)簧(huang)所(suo)儲存的(de)(de)(de)位(wei)能(neng)卻逐漸增加(jia)。當篩(shai)(shai)箱(xiang)的(de)(de)(de)運動(dong)速(su)度和動(dong)能(neng)等(deng)于零時,彈(dan)簧(huang)被壓縮到(dao)極(ji)限,它(ta)所(suo)儲存的(de)(de)(de)位(wei)能(neng)達到(dao)值,接著篩(shai)(shai)箱(xiang)向相反方向運動(dong),彈(dan)簧(huang)釋放(fang)出所(suo)儲存的(de)(de)(de)位(wei)能(neng),轉(zhuan)化為(wei)篩(shai)(shai)箱(xiang)的(de)(de)(de)動(dong)能(neng),因而篩(shai)(shai)箱(xiang)的(de)(de)(de)運動(dong)速(su)度增加(jia)。當篩(shai)(shai)箱(xiang)的(de)(de)(de)運動(dong)速(su)度和動(dong)能(neng)達到(dao)值時,彈(dan)簧(huang)伸長到(dao)極(ji)限,所(suo)儲存的(de)(de)(de)位(wei)能(neng)也小(xiao)(xiao)。的(de)(de)(de)工(gong)作(zuo)原理:振(zhen)(zhen)動(dong)篩(shai)(shai)通過產生振(zhen)(zhen)動(dong)的(de)(de)(de)振(zhen)(zhen)動(dong)器,將振(zhen)(zhen)動(dong)傳遞給篩(shai)(shai)箱(xiang),篩(shai)(shai)箱(xiang)可以(yi)自由(you)振(zhen)(zhen)動(dong),使顆粒產生近乎(hu)垂直于篩(shai)(shai)面的(de)(de)(de)跳動(dong)或(huo)作(zuo)圓形、橢圓形運動(dong)。振(zhen)(zhen)動(dong)篩(shai)(shai)適用于細粒廢物(0.1-15mm)的(de)(de)(de)篩(shai)(shai)。

共振篩的工作原理和性能:共(gong)(gong)(gong)振(zhen)(zhen)(zhen)(zhen)篩(shai)(shai)(shai)系根(gen)據彈(dan)(dan)(dan)簧(huang)共(gong)(gong)(gong)振(zhen)(zhen)(zhen)(zhen)原理制成。施予彈(dan)(dan)(dan)簧(huang)以(yi)外拉(la)玏,彈(dan)(dan)(dan)簧(huang)將伸長,外力(li)(li)取(qu)消后彈(dan)(dan)(dan)簧(huang)將發(fa)生振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)。由(you)于彈(dan)(dan)(dan)簧(huang)有內摩擦力(li)(li)(阻(zu)尼),故(gu)振(zhen)(zhen)(zhen)(zhen)幅將愈來愈小,將停止(zhi)振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)。在(zai)振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)過程中如能周期性地(di)施以(yi)外力(li)(li),此外力(li)(li)恰等于彈(dan)(dan)(dan)簧(huang)內阻(zu)力(li)(li),則振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)將保持(chi)下(xia)(xia)(xia)(xia)(xia)去。利(li)用(yong)這種原理制成的(de)(de)篩(shai)(shai)(shai)子稱(cheng)共(gong)(gong)(gong)振(zhen)(zhen)(zhen)(zhen)篩(shai)(shai)(shai)。 彈(dan)(dan)(dan)性連(lian)桿式(shi)共(gong)(gong)(gong)振(zhen)(zhen)(zhen)(zhen)篩(shai)(shai)(shai)的(de)(de)結構如下(xia)(xia)(xia)(xia)(xia)圖所示: 當傳(chuan)動(dong)(dong)(dong)(dong)機(ji)構(曲柄連(lian)桿)的(de)(de)偏心(xin)軸(zhou)旋轉時(shi),裝在(zai)偏心(xin)軸(zhou)上的(de)(de)彈(dan)(dan)(dan)性連(lian)桿迫使(shi)上篩(shai)(shai)(shai)箱(xiang)發(fa)生振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)。當上篩(shai)(shai)(shai)箱(xiang)振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)時(shi),通過板(ban)彈(dan)(dan)(dan)簧(huang)將振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)傳(chuan)給下(xia)(xia)(xia)(xia)(xia)篩(shai)(shai)(shai)箱(xiang),同(tong)時(shi)在(zai)橡(xiang)膠彈(dan)(dan)(dan)簧(huang)的(de)(de)作(zuo)(zuo)用(yong)下(xia)(xia)(xia)(xia)(xia)使(shi)下(xia)(xia)(xia)(xia)(xia)篩(shai)(shai)(shai)板(ban)彈(dan)(dan)(dan)簧(huang)將振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)傳(chuan)給下(xia)(xia)(xia)(xia)(xia)篩(shai)(shai)(shai)箱(xiang),同(tong)時(shi)在(zai)橡(xiang)膠彈(dan)(dan)(dan)簧(huang)的(de)(de)作(zuo)(zuo)用(yong)下(xia)(xia)(xia)(xia)(xia)使(shi)下(xia)(xia)(xia)(xia)(xia)篩(shai)(shai)(shai)箱(xiang)與(yu)上篩(shai)(shai)(shai)箱(xiang)發(fa)生共(gong)(gong)(gong)振(zhen)(zhen)(zhen)(zhen),上、下(xia)(xia)(xia)(xia)(xia)篩(shai)(shai)(shai)箱(xiang)作(zuo)(zuo)振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)角為(wei)45°方向的(de)(de)相(xiang)對運(yun)動(dong)(dong)(dong)(dong)。此時(shi),處(chu)在(zai)上、下(xia)(xia)(xia)(xia)(xia)篩(shai)(shai)(shai)箱(xiang)上的(de)(de)橡(xiang)膠彈(dan)(dan)(dan)簧(huang)不斷地(di)進行能量交換,即動(dong)(dong)(dong)(dong)能和位能的(de)(de)相(xiang)互(hu)轉化,使(shi)篩(shai)(shai)(shai)子獲得振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)。因為(wei)上下(xia)(xia)(xia)(xia)(xia)篩(shai)(shai)(shai)箱(xiang)振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)方向相(xiang)反(fan),故(gu)整個篩(shai)(shai)(shai)子工作(zuo)(zuo)很平。
