本發明涉及配(pei)料皮(pi)(pi)帶秤(cheng)(cheng)技術領(ling)域(yu),具體涉及一(yi)種(zhong)配(pei)料皮(pi)(pi)帶秤(cheng)(cheng)斷軸檢測報警(jing)系統(tong)。
背景技術:
配(pei)料(liao)(liao)皮帶秤是(shi)燒結、球(qiu)團(tuan)等(deng)爐料(liao)(liao)生產過程中的(de)(de)關鍵設備,其主要(yao)工作(zuo)原理是(shi):安裝在(zai)配(pei)料(liao)(liao)皮帶秤驅(qu)動電機上(shang)的(de)(de)速度(du)(du)傳感(gan)器檢測速度(du)(du)信號(hao)(hao),安裝在(zai)配(pei)料(liao)(liao)皮帶秤架上(shang)的(de)(de)稱重(zhong)傳感(gan)器檢測重(zhong)量信號(hao)(hao),通過速度(du)(du)信號(hao)(hao)和重(zhong)量信號(hao)(hao)計算出(chu)配(pei)料(liao)(liao)皮帶秤的(de)(de)瞬(shun)時流(liu)量。
配(pei)(pei)料(liao)(liao)(liao)皮(pi)(pi)(pi)(pi)帶(dai)秤(cheng)(cheng)運行的(de)(de)穩(wen)定(ding)可(ke)靠與否將直接(jie)影響爐(lu)料(liao)(liao)(liao)生產(chan)過程(cheng)的(de)(de)穩(wen)定(ding)性以及成品爐(lu)料(liao)(liao)(liao)的(de)(de)化學(xue)成分。但是(shi),在(zai)(zai)(zai)實際(ji)生產(chan)過程(cheng)中,配(pei)(pei)料(liao)(liao)(liao)皮(pi)(pi)(pi)(pi)帶(dai)秤(cheng)(cheng)會(hui)受到各(ge)種(zhong)因素的(de)(de)干擾(rao)而影響其正常(chang)配(pei)(pei)料(liao)(liao)(liao),例如當配(pei)(pei)料(liao)(liao)(liao)皮(pi)(pi)(pi)(pi)帶(dai)秤(cheng)(cheng)的(de)(de)驅動(dong)軸(zhou)(zhou)發(fa)生意(yi)外(wai)斷(duan)裂(lie)時(shi),皮(pi)(pi)(pi)(pi)帶(dai)因失(shi)去(qu)驅動(dong)而停止運轉下料(liao)(liao)(liao),但是(shi)由于此時(shi)皮(pi)(pi)(pi)(pi)帶(dai)上(shang)的(de)(de)物(wu)料(liao)(liao)(liao)重量(liang)仍作用在(zai)(zai)(zai)稱重傳(chuan)感器上(shang)、并且(qie)安裝(zhuang)在(zai)(zai)(zai)皮(pi)(pi)(pi)(pi)帶(dai)秤(cheng)(cheng)驅動(dong)電機上(shang)的(de)(de)速度傳(chuan)感器依舊能(neng)檢測到速度信(xin)號,導致皮(pi)(pi)(pi)(pi)帶(dai)秤(cheng)(cheng)仍有瞬時(shi)流量(liang)輸(shu)出(chu),進(jin)而導致實際(ji)配(pei)(pei)料(liao)(liao)(liao)出(chu)現偏差;如配(pei)(pei)料(liao)(liao)(liao)皮(pi)(pi)(pi)(pi)帶(dai)秤(cheng)(cheng)斷(duan)軸(zhou)(zhou)故障長(chang)時(shi)間不被(bei)發(fa)現,將會(hui)造成大批量(liang)的(de)(de)成品爐(lu)料(liao)(liao)(liao)成分不合格,造成嚴重的(de)(de)生產(chan)質量(liang)事(shi)故。因而亟需發(fa)明一種(zhong)能(neng)夠實時(shi)在(zai)(zai)(zai)線對運行中的(de)(de)配(pei)(pei)料(liao)(liao)(liao)皮(pi)(pi)(pi)(pi)帶(dai)秤(cheng)(cheng)進(jin)行斷(duan)軸(zhou)(zhou)檢測的(de)(de)系(xi)統。
