摘要
深锥浓密机是膏体处置技术的关键设备,高径比是影响底流浓度的重要因素,有必要探讨高径比与底流浓度之间的关系。以集料物理特性参数平均取值所需深锥浓密机高径比为基准,建立一种基于高径比的深锥浓密机底流浓度数学模型。该模型的核心是对修正系数A的取值,为了便于理论求解修正系数A,构建了一个理论压缩模型,借助理论压缩模型,计算修正系数A的理论值为5.43%;采用深锥模型实验求得系数A的值为5.14%,与理论计算值高度吻合。选取两台具有代表性的深锥浓密机参数对模型进行检验,结果表明,该模型对深锥膏体浓密机底流浓度预测较为可靠。
The deep cone thickener is the key equipment in the paste disposal technology.The height to diameter ratio is an important factor which influences the thickener＇s underflow concentration.So it is necessary to analyze the relationship between each other.Based on the aggregate＇s average physical parameters required that the height to diameter ratio,a mathematical model of deep cone thickener underflow concentration is established.The core of this model is for the correction coefficient A＇s value.So a theory compaction model is built for easily to solve the correction coefficient A＇s value.The A＇s theoretical calculation is 5.43% by this theory compaction model.And A＇s laboratory experiment result is 5.14% by using deep cone model.That is highly matched with the theoretical calculated value.Then this model was tested by two typical deep cone thickeners.The results show that the model can predict the underflow concentration of deep cone thickener reliably.
