文章摘要：深錐濃密機(jī)是膏體處置技術(shù)的關(guān)鍵設(shè)備,高徑比是影響底流濃度的重要因素,有必要探討高徑比與底流濃度之間的關(guān)系。以集料物理特性參數(shù)平均取值所需深錐濃密機(jī)高徑比為基準(zhǔn),建立一種基于高徑比的深錐濃密機(jī)底流濃度數(shù)學(xué)模型。該模型的核心是對(duì)修正系數(shù)A的取值,為了便于理論求解修正系數(shù)A,構(gòu)建了一個(gè)理論壓縮模型,借助理論壓縮模型,計(jì)算修正系數(shù)A的理論值為5.43%;采用深錐模型實(shí)驗(yàn)求得系數(shù)A的值為5.14%,與理論計(jì)算值高度吻合。選取兩臺(tái)具有代表性的深錐濃密機(jī)參數(shù)對(duì)模型進(jìn)行檢驗(yàn),結(jié)果表明,該模型對(duì)深錐膏體濃密機(jī)底流濃度預(yù)測(cè)較為可靠。

Abstr：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.
