Abstract
The invention provides a method for quickly testing the concentration of non-uniform slurries, comprising: in each sampling, making the liquid level of the slurry in a concentration pot being lower than an overflow line, getting a total weight (G1); adding pure liquid of the slurry along the edge of the concentration pot, to make the slurry volume reach a fixed value of 1000ml, getting a total weight (G2); according to a calculation formula: concentration (C)=(1000-G2-368)*p/(p-1)/(G1-368), calculating the concentration of the slurry. The method can improve the accuracy of fast concentration test on non-uniform slurries.
Description
Technical field
The present invention relates to a kind of method of fast measuring heterogeneous slurry concentration, be specially adapted to the fast-field evaluation of the heterogeneous slurry concentration of industries such as mine, chemical industry, environmental protection.
Background technology
In the mine, the production scene of industry such as chemical industry, environmental protection, for in time grasping this important procedure quality index of slurry concentration (as the ore grinding pulp density in the ore dressing plant ore-dressing practice flow process) in the production procedure, for the adjustment and the control of the technical indicator of whole production flow process obtains the relevant art parameter, generally adopt concentration kettle fast measuring.Its principle is to utilize the density of known liquid phase substance (to be generally water, 1 grams per milliliter), the weight (368 gram) and the volume (1000 milliliters) of the density (ρ grams per milliliter) of solid matter, concentration kettle, calculate * ρ/(ρ-1)/(G-368) of the concentration C of slurry=(1000-G-368) by the general assembly (TW) (G) that weighs up 1000 milliliters of slurries and concentration kettle.From concentration kettle fast measuring principle, when measuring the ideal uniform slurry, the unnecessary slurry (generally all can occur during fast-field evaluation) in the implantation concentration kettle can flow out voluntarily, and can not influence slurry sample (physics) character in the kettle, and promptly its concentration can not change; But on-site measurement generally all is that liquid-solid phase is mixed heterogeneous slurry, slurry in the implantation concentration kettle can produce the sedimentation layering immediately, unnecessary slurry is arranged when concentration kettle top overflow vent flows out, flowing out slurry must be that the littler slurry of density (as water) is in the majority, the physical property of slurry sample in the kettle is changed, the concentration accuracy that determines is descended, influence the judgement of production target or technological parameter.
Summary of the invention
Purpose of the present invention just provides a kind of method of fast measuring heterogeneous slurry concentration, and this method can improve the accuracy of measuring heterogeneous slurry concentration.
Purpose of the present invention can realize by following scheme: when taking a sample, make the liquid level of slurry in the concentration kettle be lower than overflow line at every turn, weigh up its general assembly (TW) (G
1), for the volume that makes slurry reaches fixing 1000 milliliters, add the pure liquid phase (generally being water) in the slurry again along concentration kettle edge, what overflow when unnecessary is pure liquid phase (generally being water), weighs up its general assembly (TW) (G then
2).Like this, although changed physical property---the concentration of slurry in the concentration kettle, pass through G
2Can calculate the weight (volume) of solid matter in the kettle, calculate G then
1The weight (volume) of middle water calculates G at last
1The time kettle in the original concentration of slurry.Computing formula: concentration (C)=(1000-G
2-368) * ρ/(ρ-1)/(G
1-368).
The invention has the beneficial effects as follows: do not change concentration kettle measuring principle, still have under the situation simple, convenient, the easily fast measuring characteristics of row, by changing measuring and operating method and computing formula, reached the purpose of practical raising fast measuring heterogeneous slurry concentration accuracy.
