【摘要】：離心選礦機(jī)是重選領(lǐng)域中一種非常重要的選礦設(shè)備。重力選礦就是對(duì)所采集到的相應(yīng)礦物原料,根據(jù)其礦物的物理性質(zhì)、物理化學(xué)性質(zhì)和化學(xué)性質(zhì)的不同特征,篩選出有用礦物的過程。離心選礦機(jī)由于引入了離心力,使得礦料的分選效果和效率被大大提升,因此它在選礦領(lǐng)域被廣泛而大量地運(yùn)用。本課的研究是對(duì)一選礦廠擴(kuò)建項(xiàng)目中使用的選礦離心機(jī)的控制系統(tǒng)進(jìn)行改造,在整個(gè)項(xiàng)目中總共使用32臺(tái)選礦離心機(jī),與同類情況相比,其數(shù)量可觀。為提高單位時(shí)間的處理量,提高選礦效率,選用現(xiàn)有使用中轉(zhuǎn)鼓最大的2m選礦離心機(jī)。為實(shí)現(xiàn)高效、穩(wěn)定控制,結(jié)合當(dāng)前控制系統(tǒng)技術(shù)發(fā)展的現(xiàn)狀及生產(chǎn)的實(shí)際需要,基于PLC變頻技術(shù)和HMI技術(shù),采用施耐德ModiconM340 PLC對(duì)臥式離心選礦機(jī)進(jìn)行控制,人機(jī)界面Magelis GXO進(jìn)行動(dòng)態(tài)監(jiān)控,設(shè)計(jì)了2m離心機(jī)“觸摸屏+可編程控制器+變頻器+網(wǎng)絡(luò)+控制對(duì)象”的控制系統(tǒng),通過實(shí)際驗(yàn)證,該控制系統(tǒng)能實(shí)現(xiàn)穩(wěn)定高效生產(chǎn),很大程度的提高了經(jīng)濟(jì)效益。為獲取控制系統(tǒng)所需的關(guān)鍵參數(shù),本文對(duì)2m變頻離心選礦機(jī)的基本工作原理和分選原理及發(fā)展現(xiàn)狀進(jìn)行了研究,并通過實(shí)驗(yàn),獲取影響選礦效果的關(guān)鍵參數(shù)信息。為滿足項(xiàng)目使用的要求同時(shí)控制成本,本文采用施耐德施耐德產(chǎn)品ModiconM340可編程控制器,針對(duì)32臺(tái)離心機(jī)兩地控制要求,按適度集中的原則設(shè)計(jì)控制系統(tǒng),采用一拖四的設(shè)計(jì)方案,即一個(gè)控制柜中安裝一套可編程控制器,一套可編程控制器控制4臺(tái)選礦離心機(jī)。同時(shí)采用Modbus現(xiàn)場(chǎng)總線交換技術(shù)實(shí)現(xiàn)可編程控制器與變頻器之間的通訊。為更加便于控制和監(jiān)視,實(shí)現(xiàn)系統(tǒng)工作狀況的可視化及系統(tǒng)工作狀況的可追溯要求,更方便地實(shí)現(xiàn)對(duì)系統(tǒng)工作參數(shù)的設(shè)置,引入了HMI技術(shù)。可通過以太網(wǎng)接口的可編程控制器與監(jiān)控中心的上位機(jī)聯(lián)網(wǎng),形成規(guī)模較大的快速控制網(wǎng)絡(luò),實(shí)現(xiàn)實(shí)時(shí)監(jiān)控與控制。本文通過結(jié)合2m離心選礦機(jī)的工藝特點(diǎn),采用PLC變頻和HMI技術(shù),對(duì)2m變頻離心選礦機(jī)的控制進(jìn)行系統(tǒng)設(shè)計(jì),降低了工人的勞動(dòng)強(qiáng)度,提高了選礦工作效率,保證了質(zhì)量,且操作界面友好,可實(shí)時(shí)監(jiān)控、安全可靠的性能。通過本次研究,保證了企業(yè)順利實(shí)現(xiàn)生產(chǎn)目標(biāo),提高了產(chǎn)量,合理節(jié)能,創(chuàng)造了經(jīng)濟(jì)和社會(huì)效益,并且為針對(duì)規(guī)模化控制離心選礦機(jī)的工作模式提供了實(shí)踐經(jīng)驗(yàn)和技術(shù)參考。
[Abstract]:Centrifugal concentrator is a very important equipment in the field of gravity separation. Gravity dressing is the different characteristics of the corresponding mineral raw materials, according to the physical properties, physicochemical properties and chemical properties of their minerals. The process of screening out useful minerals. The centrifugal concentrator has introduced centrifugal force, which has greatly improved the separation efficiency and efficiency of the ore. Therefore, it is widely and extensively used in the field of mineral processing. The research in this course is to reform the control system of the concentrator used in the expansion project of a concentrator. In total, 32 centrifuges are used in the whole project. In order to increase the processing capacity per unit time and improve the dressing efficiency, the 2m centrifuge, which has the largest drum in use, is used to achieve high efficiency and stable control. Based on PLC frequency conversion technology and HMI technology, the horizontal centrifugal concentrator is controlled by Schneider ModiconM340 PLC and the man-machine interface Magelis GXO is dynamically monitored. The control system of 2m centrifuge "Programmable Controller Inverter Network Control object on Touch screen" is designed. It is proved by practice that the control system can realize stable and efficient production. In order to obtain the key parameters of the control system, the basic working principle, separation principle and development status of 2m frequency conversion centrifugal concentrator are studied in this paper. In order to meet the requirements of project use and control cost, this paper adopts Schneider Schneider product ModiconM340 programmable controller to control 32 centrifuges. The control system is designed according to the principle of moderate centralization, and the design scheme of "one drag four" is adopted, that is, a set of programmable controller is installed in a control cabinet. A set of programmable logic controller (PLC) is used to control 4 ore dressing centrifuges. At the same time, Modbus fieldbus exchange technology is used to realize the communication between programmable controller and frequency converter. In order to realize the visualization of the system working condition and the traceability of the system working condition, it is more convenient to set the working parameters of the system. The HMI technology is introduced. The programmable controller can be connected with the upper computer of the monitoring center through the Ethernet interface. A large scale fast control network is formed to realize real-time monitoring and control. The control of 2m centrifugal concentrator is systematically designed by using PLC frequency conversion and HMI technology combined with the technological characteristics of 2m centrifugal concentrator. It reduces the labor intensity of workers, improves the efficiency of ore dressing, ensures the quality, friendly operation interface, real-time monitoring, safe and reliable performance. Reasonable energy saving creates economic and social benefits and provides practical experience and technical reference for the work mode of large-scale control centrifugal concentrator.
