矿浆多参数在线检测系统设计

针对现有矿浆浓度检测系统存在的测量数据单一、取样过程易沉降、难以检验所取样品均匀性等缺点,设计了一种矿浆多参数在线检测系统。基于称重法测量原理实现对矿浆浓度、体积流量、质量流量等多参数的在线检测。使用基于旋流消能法的取样器实现对原矿浆均匀化及防沉降处理。基于水力学孔流原理实现对取样矿浆的均值化处理及均匀性检验。在云南某选矿厂的长期应用结果表明:检测系统所测数据与浓度壶所测数据差值在2%以内,满足工业精度要求。由取样器取出样品的不均匀度在1%以内,取样过程未出现沉降、堵塞等现象,取样效果良好。

Design of multi-parameter online measurement system for pulp

Aiming at the shortcomings of the existing pulp concentration measurement system, such as single measurement data, easy settlement of sampling process, and difficulty in testing the uniformity of samples taken, a multi-parameter on-line measurement system for slurry was designed. On-line measurement of multiple parameters such as slurry concentration, volume flow, mass flow rate, etc. based on the weighing method measurement principle. The homogenization and anti-settling treatment of the original slurry is realized by using a sampler based on the swirling energy dissipating method. Based on the principle of hydraulic pore flow, the mean value treatment and uniformity test of the sampled slurry are realized. The long-term application results of a concentrator in Yunnan indicate that the difference between the measured data of the measurement system and the data measured by the concentration pot is within 2%, which meets the requirements of industrial precision. The unevenness of the sample taken by the sampler is within 1%, and the sampling process No sedimentation, blockage, etc. occurred, and the sampling effect was good.
