浅谈浮选槽液位自动控制在选矿厂的应用

Discussion on Application of Automatic Control of Liquid Level in Flotation Tank in Mineral Processing Plant

浮选作为选矿的一个重要环节,决定了选矿质量的高低,浮选效果的好坏与浮选槽液位的控制有直接关系。结合工程实际,探讨了浮选槽液位自动控制系统的原理、过程及实现方法,浮选槽液位采用了智能化模糊控制算法,浮选机矿浆液位自动控制系统由矿浆液位测量装置、液位控制仪表箱、气动调节阀组成。通过工程实际应用结果表明,该液位自动控制系统具有先进、经济、实用、耐用、稳定的特点。

Flotation,as an important part of the beneficiation,determines the quality level of beneficia-tion;the flotation effect is directly related to control of liquid level of the flotation tank.The automatic control system of liquid level in the flotation tank was discussed based on the engineering practice,the principle,process and realization method.Intelligent fuzzy control algorithm was used in flotation tank liquid level.The liquid level automatic control system of the pulp flotation machine consists of pulp level measuring device,level control instrumentation boxes,pneumatic control valves.The practical applica-tion results show that the liquid level automatic control system has the characteristics of advanced,eco-nomical,practical,durable and stable.
