Design Of Molybdenum Ore Dressing Flotation Automatic Dosing System Based On FCS

Dosing is one of the very important links in the process of molybdenum mineral flotation; the flotation efficiency directly affects the non-ferrous metal molybdenum. Molybdenum as an effect than rare non-ferrous metal industry, its application is very extensive, but as a non renewable resource, we should cherish and protect, at the same time, out of the need of environmental protection also does not allow us to waste resources, so to improve the flotation efficiency of molybdenum is very important social and economic benefit. Improve the level of automation in the flotation process, is an effective way to improve the flotation efficiency, FCS field bus control system automation, as now the most advanced control solutions, has the very strong advantages, FCS has the advantages of simple structure, advanced concepts, strong openness, high maintainability, at the same time FCS the concept covers corporate management, the middle control layer and field execution layer, which is the organic combination of production and management to improve the management of the entire flotation plant and informatization level.Automatic dosing system whose main task is to precisely control the feeding speed, the control object is adding electromagnetic valve each dosing point, control principle is the principle of switching time of the outlet flow control valve in the chemical dosing period, the premise is to ensure the chemical dosing valve box level at a constant level, at the same time, the level of maximum dosing rate per unit of time of the dosing solenoid valve, and then to calculate the ratio between the switching time of the solenoid valve in the chemical dosing period, so as to obtain the goal of feeding speed. This paper introduces the application of FCS field bus control system in Jinduicheng molybdenum ore dressing flotation Baihualing automatic dosing system, from the application of needs analysis, system selection, design, implementation, testing, debugging, to the final completion of the project, is a whole process of organic unity. The specific content is determined according to the needs analysis, target and task, comparative analysis of the mainstream control system at the present stage, according to the characteristics of tasks and goals and choose FCS as the control structure of the system, and then a detailed description of the realization of automatic dosing system and the design of the hardware system, software system, network system three then, the debugging and testing of the automatic dosing system overall design, the hardware equipment of the system is stable and reliable, friendly interface, easy to operate software and upgrades, various technical indicators have reached the design requirements of. then the automatic dosing system design has been completed and fully tested machine debugging the system hardware is stable, reliable, friendly software interface, easy to operate and upgrade the technical indicators meet the design requirements.
