【摘要】：選礦廠選別工藝工序解離與分選,影響礦石分離指標的生產(chǎn)過程。選別工藝指標不僅與選別設備有關,而且與破礦粒度、給水量、給礦量及生產(chǎn)操作質(zhì)量有關。老式球磨機在設備性能及能量消耗,臺時處理,礦量處理都無法達到生產(chǎn)技術(shù)要求。隨著科學技術(shù)的飛速發(fā)展,傳感器技術(shù)、信號傳輸技術(shù)、網(wǎng)絡技術(shù)和軟件技術(shù)的綜合應用,使得選別工藝球磨分級生產(chǎn)實現(xiàn)了集中操作控制,自動化在線監(jiān)測、信號同步傳輸,以及趨勢預報成為可能。利用集中操作監(jiān)測的自動化系統(tǒng)實現(xiàn)實時數(shù)據(jù)監(jiān)測,管控一體化生產(chǎn)管理的發(fā)展方向。選礦廠磨礦分級過程自動控制可分為定值控制和最優(yōu)化控制兩種方式。在分析IFIX組態(tài)數(shù)據(jù)技術(shù)以及相關的TCP/IP技術(shù)的基礎上,實現(xiàn)監(jiān)控終端的軟硬件設計、監(jiān)控中心的軟件設計、監(jiān)控數(shù)據(jù)的采集與傳輸?shù)�。有助于礦山應急部門和相關單位進行實時監(jiān)控、監(jiān)視和預測精礦品位的變化,為原礦產(chǎn)量、破礦指標及球團料品位指標提供一種準確實時數(shù)據(jù)主控制系統(tǒng)擬采用新型的、統(tǒng)一的開放式控制模式,取代傳統(tǒng)的PLC、DCS分控模式�？刂凭W(wǎng)絡采用雙層網(wǎng)絡結(jié)構(gòu),下層采用PLC控制網(wǎng),上層采用光纖以太環(huán)網(wǎng)。主要參數(shù)的在線檢測、控制、記錄、報警、管理、提供給上一級機關一個實時的網(wǎng)絡數(shù)據(jù)庫。通過計算機支撐系統(tǒng)實現(xiàn)信息管理、優(yōu)化控制和過程控制的集成,從而實現(xiàn)選礦生產(chǎn)過程的綜合自動化。該系統(tǒng)實現(xiàn)二十四小時不間斷地實施監(jiān)測,并提供能夠反應球磨運行狀態(tài)的給礦量、給礦濃度、旋流器礦漿流量等數(shù)據(jù)。以便實時分析整個選別工藝設備之間的變化情況,確保球磨機的安全穩(wěn)定運行。通過電動閥遠程控制補加水、返砂水水量調(diào)節(jié),用超聲波水位計監(jiān)測泵池液位,通過品位儀、粒度儀實時監(jiān)測精礦品位、給礦粒度達到有效生產(chǎn)操作。用concept語句編程實現(xiàn)PLC可編程控制器控制,IFIX組態(tài)畫面平臺。通過開發(fā)的軟件,能把采集到的數(shù)據(jù)進行保存、分析,通過實現(xiàn)工業(yè)以太網(wǎng)環(huán)形網(wǎng)絡進行生產(chǎn)安全預測,生產(chǎn)管理、過程控制、基礎自動化三層管理級別的應用,實現(xiàn)全過程參數(shù)計算和優(yōu)化、數(shù)據(jù)和質(zhì)量跟蹤、生產(chǎn)順序控制和管理。
[Abstract]:Separation and separation of ore separation process in concentrator affect the production process of ore separation index. The separation process index is not only related to the separation equipment, but also to the ore breaking grain size, water supply, ore feed quantity and production operation quality. The old ball mill can not meet the technical requirements in equipment performance, energy consumption, stage time treatment and ore quantity treatment. With the rapid development of science and technology, the integrated application of sensor technology, signal transmission technology, network technology and software technology, make the separation process ball mill grading production to achieve centralized operation control, automatic on-line monitoring, signal synchronous transmission, And trend forecasts are possible. The automatic system of centralized operation and monitoring is used to realize real-time data monitoring and the development direction of integrated production management of management and management. Automatic control of grinding and classification process in concentrator can be divided into two ways: fixed value control and optimal control. Based on the analysis of IFIX configuration data technology and related TCP/IP technology, the hardware and software design of monitoring terminal, the software design of monitoring center, the collection and transmission of monitoring data and so on are realized. It is helpful for mine emergency departments and related units to monitor and predict the change of concentrate grade in real time, and to provide a new type of master control system with accurate real-time data for raw ore production, ore breaking index and pellet grade index. The unified open control mode replaces the traditional PLC,DCS control mode. The control network adopts double layer network structure, the lower layer adopts PLC control network, and the upper layer adopts optical fiber Ethernet ring network. Main parameters online detection, control, recording, alarm, management, to provide a real-time network database for higher authorities. The integration of information management, optimization control and process control is realized by computer support system, and the comprehensive automation of mineral processing process is realized. The system can carry out monitoring continuously for 24 hours, and provide the data of ore feed quantity, ore feed concentration and cyclone slurry flow rate which can respond to the operation state of ball mill. In order to analyze the change of the whole separation process equipment in real time and ensure the safe and stable operation of the ball mill. The water level of pump pool is monitored with ultrasonic water level meter through remote control of recharge water by electric valve, and concentrate grade is monitored in real time by grade meter and particle size meter, and the ore grain size reaches effective production operation. PLC programmable controller control and IFIX configuration screen platform are realized by concept statement programming. Through the developed software, the collected data can be saved and analyzed, and through the realization of industrial Ethernet ring network, the application of production safety prediction, production management, process control and basic automation management level can be carried out. Achieve the whole process parameter calculation and optimization, data and quality tracking, production sequence control and management.
