隨著計(ji)算機技術(shu)與自(zi)動(dong)(dong)(dong)化技術(shu)的發展，自(zi)動(dong)(dong)(dong)配料系(xi)統的相關(guan)技術(shu)也(ye)日益成熟,并以(yi)(yi)其計(ji)量準確、安全(quan)可靠(kao)、自(zi)動(dong)(dong)(dong)化程度高,廣泛地應用于化工、礦山、建材(cai)、食品、冶金、港口、電力等多種行(xing)業。它既(ji)可以(yi)(yi)自(zi)成系(xi)統,獨立(li)工作,也(ye)可以(yi)(yi)接入DCS、FCS系(xi)統.以(yi)(yi)下介紹的自(zi)動(dong)(dong)(dong)配料技術(shu)設計(ji)合理、精度高、運行(xing)可靠(kao),可完全(quan)替代(dai)進口產品。
自(zi)動配(pei)料(liao)系(xi)統工作原理
自動配料(liao)系(xi)(xi)統(tong)由數臺配料(liao)皮帶秤(cheng)及其(qi)稱(cheng)重顯示控制(zhi)器(qi)、傳感器(qi)、供橋板 和供 電系(xi)(xi)統(tong)組成系(xi)(xi)統(tong)原(yuan)理如圖1所示，
該(gai)系(xi)統采(cai)用(yong)自(zi)己(ji)研制(zhi)(zhi)(zhi)的(de)ICS-XF型(xing)單通(tong)道(dao)兩托(tuo)輥配(pei)料皮帶機(ji),該(gai)機(ji)穩定可(ke)靠,外(wai)協(xie)件和(he)外(wai)購(gou)件都選用(yong)國內(nei)外(wai)具(ju)有工藝技術(shu)的(de)廠(chang)家產品，以保(bao)證配(pei)料系(xi)統的(de)安(an)全可(ke)靠。稱重(zhong)顯示(shi)(shi)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)器(qi)的(de)數據(ju)采(cai)集電路(lu)采(cai)集的(de)物料重(zhong)量信(xin)(xin)號和(he)皮帶速度(du)(du)信(xin)(xin)號經(jing)PID調節,輸(shu)(shu)出(chu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)信(xin)(xin)號,由(you)RS-485輸(shu)(shu)送去控(kong)(kong)(kong)制(zhi)(zhi)(zhi)變頻器(qi).從而控(kong)(kong)(kong)制(zhi)(zhi)(zhi)皮帶機(ji)的(de)電機(ji)轉速與皮帶速度(du)(du),達到控(kong)(kong)(kong)制(zhi)(zhi)(zhi)物料流量的(de)目的(de).XK3101型(xing)稱重(zhong)顯示(shi)(shi)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)器(qi)為(wei)一智能型(xing)儀(yi)表(biao),具(ju)有輸(shu)(shu)人、顯示(shi)(shi).控(kong)(kong)(kong)制(zhi)(zhi)(zhi)及通(tong)信(xin)(xin)功能。其采(cai)用(yong)16位單片處理器(qi),運算速度(du)(du)快,控(kong)(kong)(kong)制(zhi)(zhi)(zhi)能力(li)強,可(ke)行性高.
