Description
Technical field
The invention belongs to metallurgy and mine ore dressing technical fields, and it is crosscutting respectively adjustable to be related to a kind of incompatible fluid of solid-liquid
Automatic sampling device.
Background technique
In recent years, it is online to have introduced advanced grade in order to obtain better ore-dressing technique index for metallurgy and Mineral Processing Industry
Analysis system.In order to ensure grade on-line analysis system is in Instructing manufacture, reduction reagent consumption, reduction water resources consumption, control
Product quality and the raising useful metal rate of recovery etc. obtain good effect, and should upgrade on-line analysis system first
Running quality.For the running quality for on-line analysis system of upgrading, the best of grade on-line analysis system should be established first
Mathematical model first has to solve the problems, such as be that should obtain representative to establish the optimum mathematics model of grade on-line analysis system
Property the high calibration sample of strong, broad covered area, sampling accuracy.Calibration sample is usually the mine plasm intercepted from pipe sampler
In, it is obtained after more careful, more accurate secondary interception.
In order to provide to grade on-line analysis system, representativeness is stronger, covering surface is wider, the higher calibration sample of accuracy
Product, we must be strictly controlled the top 5 factor for obtaining calibration sample: sampling method, sample time, sampling in sampling process
Duration, sampling weight, sampling interval time.Scene obtains the method for calibration sample at present and that there are problems is as follows:
(1), sampling method mainly includes manual sampling method and automatic sampling method, and manual sampling method is generally utilized by sampling personnel and taken
Sample pot or sample spoon are sampled.Although the sampling method can quickly obtain sample, the sampling method it is accurate
Degree is but affected by factors such as technical level, responsibility consciousness, the occupation spirits of sampling personnel.If it is more to sample number
When, sampling precision level is then even more sharply to decline.Automatic sampling method generally use the Automatic Sampler for Mineral Slurry of commercial type into
Row sampling, automatic sampling method are generally used for intercepting mine plasm from process pipe.This method is big with sampling amount, equipment is multiple
Feature miscellaneous, high to requirements of installation space.There is also be unable to satisfy grade in-line analyzer to calibration sample in this way
The special requirements such as sample time is changeable, sampling duration is of short duration, sampling interval time is adjustable, sampling weight is smaller.
(2), sample time is generally divided into set time sampling and random time samples two kinds.Set time sampling refers to solid
Daily when be sampled be scheduled on.Use when set time sampling is generally used for establishing optimum mathematics model.When random
Between sampling refer to sample time unfixed sampling.Random time sampling is generally used for making when the running quality of verification mathematical model
With.
(3), duration and sampling weight are sampled.Sampling duration refers to the time span needed when intercepting single calibration sample,
Generally 5 minutes or so.Sampling weight refers to the example weight needed when obtaining single calibration sample.If the weight of calibration sample
Measure too heavy, then will increase the drying time of sample, if the weight of calibration sample is too light, calibration sample it is representative just not
By force.So the weight of calibration sample must reasonably be arranged.Under normal circumstances, grade on-line analysis system requires to be sent to laboratory
Solid weight in the calibration sample of chemical examination cannot be less than 100 grams and be not greater than 300 grams.
(4), sampling interval time refers to the time interval between two calibration samples for intercepting the same runner.Between sampling
Generally the quantity sampled is needed to determine by the same day each runner every the time.Such as the 5th runner needs to take 12 samples for one day, then
Sampling interval time is exactly 2 hours.
In conclusion due to grade on-line analysis system to sample time of calibration sample, sampling duration, sampling weight and
The particular/special requirement of sampling interval time, thus using conventional manual sampling method and commercial type Automatic Sampler for Mineral Slurry into
Row sampling, is unable to satisfy calibration sample required for grade on-line analysis system.
