⊕ 簡介(jie)

　　方形搖擺篩處理量(liang)大(da)，篩(shai)分(fen)精(jing)度(du)高(gao)，單(dan)純追(zhui)求篩(shai)分(fen)精(jing)度(du)會(hui)犧牲產量(liang)為代價，而追(zhui)求大(da)產量(liang)又會(hui)使得精(jing)度(du)下降，方(fang)型精(jing)密搖擺篩(shai)是(shi)針對上(shang)述問題而專(zhuan)門(men)設(she)計的(de)一(yi)種具(ju)有(you)高(gao)精(jing)度(du)大(da)產量(liang)的(de)篩(shai)分(fen)設(she)備(bei)，它廣泛用于(yu)化工、冶金、有(you)色金屬、非有(you)色金屬、食(shi)品、磨料等行業(ye)。

　　通過方型(xing)精密搖擺篩將(jiang)振動(dong)(dong)器發(fa)生振動(dong)(dong)加搖擺運動(dong)(dong)，傳至篩面，從而使(shi)物料(liao)在篩機前部迅速(su)分(fen)散，從而達到篩分(fen)之目(mu)的。

　　⊕ 工作原理(li)

　　從(cong)篩(shai)(shai)(shai)(shai)機(ji)(ji)搖(yao)動(dong)(dong)(dong)(dong)(dong)體(ti)即(ji)篩(shai)(shai)(shai)(shai)箱運(yun)動(dong)(dong)(dong)(dong)(dong)軌跡來看，方型搖(yao)擺(bai)篩(shai)(shai)(shai)(shai)又稱往復篩(shai)(shai)(shai)(shai)，其(qi)驅動(dong)(dong)(dong)(dong)(dong)裝置所產生的振動(dong)(dong)(dong)(dong)(dong)力是(shi)一(yi)(yi)繞(rao)定(ding)軸、方向呈規律(lv)變化的慣性(xing)(xing)力，其(qi)本質是(shi)由偏心輪繞(rao)定(ding)軸轉動(dong)(dong)(dong)(dong)(dong)所形成的往復慣性(xing)(xing)力。根據搖(yao)擺(bai)篩(shai)(shai)(shai)(shai)的結構特點及工(gong)(gong)作(zuo)(zuo)原理，其(qi)篩(shai)(shai)(shai)(shai)面(mian)(mian)一(yi)(yi)般為水(shui)平或微傾斜布置(傾斜角(jiao)度(du)為0°~5°)。搖(yao)擺(bai)篩(shai)(shai)(shai)(shai)的工(gong)(gong)作(zuo)(zuo)原理為:篩(shai)(shai)(shai)(shai)機(ji)(ji)啟動(dong)(dong)(dong)(dong)(dong)后(hou)(hou)，篩(shai)(shai)(shai)(shai)機(ji)(ji)搖(yao)動(dong)(dong)(dong)(dong)(dong)體(ti)即(ji)篩(shai)(shai)(shai)(shai)箱在慣性(xing)(xing)力的作(zuo)(zuo)用下作(zuo)(zuo)前后(hou)(hou)往復運(yun)動(dong)(dong)(dong)(dong)(dong)，篩(shai)(shai)(shai)(shai)箱帶動(dong)(dong)(dong)(dong)(dong)篩(shai)(shai)(shai)(shai)面(mian)(mian)作(zuo)(zuo)周期性(xing)(xing)搖(yao)動(dong)(dong)(dong)(dong)(dong)，從(cong)而(er)使篩(shai)(shai)(shai)(shai)面(mian)(mian)上的物(wu)(wu)料(liao)(liao)隨篩(shai)(shai)(shai)(shai)箱一(yi)(yi)同作(zuo)(zuo)定(ding)向跳(tiao)躍式運(yun)動(dong)(dong)(dong)(dong)(dong)，期間，小(xiao)于篩(shai)(shai)(shai)(shai)面(mian)(mian)孔徑(jing)的物(wu)(wu)理通過篩(shai)(shai)(shai)(shai)孔落到下層，成為篩(shai)(shai)(shai)(shai)下物(wu)(wu)，大于篩(shai)(shai)(shai)(shai)面(mian)(mian)孔徑(jing)的物(wu)(wu)料(liao)(liao)經連(lian)續翻滾跳(tiao)躍運(yun)動(dong)(dong)(dong)(dong)(dong)后(hou)(hou)從(cong)排(pai)料(liao)(liao)口排(pai)出，終完成篩(shai)(shai)(shai)(shai)分工(gong)(gong)作(zuo)(zuo)。

　　從FYBS方型搖擺篩(shai)(shai)(shai)的結構和工作原(yuan)理可以(yi)看出，其傳動機(ji)構偏心輪(lun)距(ju)物(wu)料運動軌跡及物(wu)料在(zai)篩(shai)(shai)(shai)面上的滯留時間有至關重要的影響(xiang)，也(ye)即對(dui)篩(shai)(shai)(shai)機(ji)處理能力(li)和篩(shai)(shai)(shai)分(fen)效率(lv)有相反的影響(xiang)，有鑒于此，在(zai)實際篩(shai)(shai)(shai)分(fen)作業中，我們可以(yi)根據具體(ti)情況和需(xu)要，在(zai)生(sheng)產(chan)能力(li)和篩(shai)(shai)(shai)分(fen)效率(lv)兩方面有所(suo)取(qu)舍。

⊕技(ji)術參數

　　FYBS型 搖(yao)擺篩作業原理(li)模擬

⊕ 物(wu)料在篩面上運動情況

　　同樣或相近的配置，FYBS型搖擺篩比一般慣性振動篩有(you)更高的處理能力(li)和(he)篩(shai)分效率，其本質是(shi)，該機型可人為(wei)的控制物料在(zai)篩(shai)面(mian)上(shang)的運動軌(gui)(gui)跡(ji)和(he)滯留時間，即在(zai)有(you)限(xian)空間，由于物料的運動軌(gui)(gui)跡(ji)為(wei)速(su)度(du)和(he)加速(su)度(du)均為(wei)變化非線性(xing)曲線，所以，物料與篩(shai)面(mian)有(you)更多(duo)接(jie)觸機濾，當然也就增加了透篩(shai)率。
