履(lv)帶式拋丸機用途
履帶(dai)式拋丸(wan)機綜合(he)國(guo)內外(wai)技術(shu)，是一種清理(li)效(xiao)果好、結構緊湊、噪聲小、的(de)清理(li)設備，應用于大(da)中批(pi)量生產(chan)的(de)表面(mian)除銹或拋丸(wan)強化，具有以下(xia)特點：
1、采用(yong)(yong)懸臂離心式拋丸器，具有使(shi)用(yong)(yong)壽命長、結構簡單等特點；
2、 采用75 m/s, 80 m/s, 85 m/s三種(zhong)拋射速度。
3、皮(pi)帶(dai)輪采用國際(ji)上 的快換結(jie)構(gou)，有利于提高(gao)生產效率，降低勞(lao)動強度(du)。
4、采用BE型分(fen)離(li)器，具有(you)良好的分(fen)離(li)效(xiao)果和較高的生產率(lv)，對提高葉片壽命有(you)積極的作用；
5、采用袋式(shi)除塵器(qi)，粉塵排放(fang)濃度低于標準，改善(shan)了工人(ren)的勞動環(huan)境；
6、本機(ji)(ji)型增加了手動分(fen)丸閘，出(chu)料門(men)等(deng)一些特殊機(ji)(ji)構(gou)。
7、本機(ji)型的履帶式拋(pao)丸(wan)機(ji)即(ji)可(ke)單機(ji)使(shi)用(yong)，又可(ke)配(pei)線使(shi)用(yong)。
履帶式拋(pao)丸機結(jie)構(gou)及原理
本機(ji)是(shi)一種(zhong)小型的清(qing)理設備，主要由清(qing)理室、拋丸器總成(cheng)、提升機(ji)、分離器、電(dian)氣系統等部分組成(cheng)。見圖一（表(biao)一注(zhu)明了(le)各部分序號對(dui)應的名(ming)稱）
工(gong)作原(yuan)理(li)：在清理(li)室(shi)(shi)中(zhong)(zhong)(zhong)(zhong)加入(ru)(ru)規定數量(liang)的(de)(de)工(gong)件(jian)，機器(qi)(qi)(qi)啟動后(hou)，拋丸(wan)(wan)(wan)(wan)器(qi)(qi)(qi)高速拋出(chu)的(de)(de)彈丸(wan)(wan)(wan)(wan)形成(cheng)流丸(wan)(wan)(wan)(wan)束，均勻(yun)地打擊(ji)在工(gong)件(jian)表(biao)面上，從而達到(dao)清理(li)、強化的(de)(de)目的(de)(de)。拋出(chu)的(de)(de)彈丸(wan)(wan)(wan)(wan)及砂粒(li)，流入(ru)(ru)提升機內(nei)，由(you)提升機提升到(dao)分(fen)離器(qi)(qi)(qi)中(zhong)(zhong)(zhong)(zhong)進(jin)行(xing)分(fen)離。粉塵(chen)(chen)由(you)風機吸送到(dao)除塵(chen)(chen)器(qi)(qi)(qi)中(zhong)(zhong)(zhong)(zhong)過濾，清潔空(kong)氣排入(ru)(ru)大(da)氣中(zhong)(zhong)(zhong)(zhong)，布袋(dai)上的(de)(de)灰塵(chen)(chen)經(jing)機械振打落入(ru)(ru)除塵(chen)(chen)器(qi)(qi)(qi)底部的(de)(de)集塵(chen)(chen)箱中(zhong)(zhong)(zhong)(zhong)，用(yong)(yong)戶可(ke)(ke)定期去(qu)除，廢(fei)砂由(you)廢(fei)料(liao)管流出(chu)，用(yong)(yong)戶可(ke)(ke)回用(yong)(yong)。丸(wan)(wan)(wan)(wan)砂混(hun)合物由(you)回用(yong)(yong)管收(shou)回進(jin)入(ru)(ru)室(shi)(shi)體，待分(fen)離器(qi)(qi)(qi)分(fen)離后(hou)再回用(yong)(yong)，干凈的(de)(de)彈丸(wan)(wan)(wan)(wan)由(you)電磁供丸(wan)(wan)(wan)(wan)閘門進(jin)入(ru)(ru)拋丸(wan)(wan)(wan)(wan)器(qi)(qi)(qi)拋打工(gong)件(jian)。
