Description
Technical field
The present invention relates to the real-time fields of measurement that industrial material starches stream concentration, particularly a kind of continuous ore pulp of small-sized Weighing type
Flow weight concentration measurement apparatus.
Background technology
Mine filling system, the floating system of ore dressing plant mill, chemical plant paste system, Building Materials Factory's paste system in metallurgy, make
Paper plant's black liquor system, sewage disposal system, so that in modern 3D material spray manufacture systems, thing pulp flow concentration is process industry reality
When the core parameter that controls.In slurries, thing pulp flow concentration is typically measured with weight concentration, substantially reflects flow work
Industry handles the amount and matter of material, therefore its accurate measurement and real-time stabilization control are high-quality technological process industry, high yield, low disappeared
One of basis of consumption.There is color sorting factory section time ore dressing tin metal as certain is large-scale（5 ~ 60,000 yuan/ton）The rate of recovery reduces by 5 ~ 6%, then
Lose huge, these are all limited precious resources.In many factors, it is major reason that key process parameter, which lacks monitoring in real time,
One of.
So that floating system is ground by nonferrous mineral dressing factory as an example, pulp density is measured generally by radioisotope densimeter, electricity
Magnetic flowmeter measures mineral slurry flux, calculates into slurry weight concentration, to approach the expensive of introduction（More than million yuan）
The measured value of ultrasonic wave Particle Size Analyzer or laser particle size analyzer.Even if so, set of device still needs to more than 10 ten thousand yuan of investments.Choosing
Ore deposit factory will realize the productive target of metal casting yield and Reasonable Grade, at least also want 5 ~ 6 sets of concentrations above measurement apparatus.Grind flotation
Factory typically since being fed ore grinding, in follow-up each operation adding medicine point, all adds foaming agent, therefore makes to exist in ore pulp unstable
Bubbles volume, and bubble brings larger error to radioisotope densimeter, or even is difficult with.In addition, the same position of radioactivity
The penetrate source control and protection of plain densitometer are to select factory and mine filling system problem, although during regular job, by protection specification only
It is noted that should not be for a long time close to penetrating source, its radioactivity is in safe range to body effect, but China much selects factory, ore deposit
Mountain filling lack instrument maintenance management personnel, to radioisotope densimeter grasp be not easy so that operating personnel's body by
Injury, substitutes radioisotope densimeter to be a kind of development trend with on-radiation instrument.
Necessary wear-resistant, the anticorrosive, anti-clogging of the automatic measuring instrument of ore pulp weight concentration, due to mineral ore grade ripple of digging up mine
Dynamic, dry mine density can also fluctuate, and influence the measurement accuracy of ore pulp weight concentration.And radioisotope densimeter does not possess reality
When school look into the function of dry mine variable density.Early stage is used for the U-shaped flow export overflow-type differential pressure densimeter of ore pulp weight concentration measurement,
Although its bottommost has unimpeded mouth, it is difficult to block clearing, maintenance is big, in practice it has proved that is unable to normal use.Common steel tube and valve
Also it is difficult to long-term anti-ore pulp abrasion, ore pulp pipe and ore pulp valve are all the ceramic lined or abrasive rubber with abrasion-proof corrosion-proof at present,
But the grit in ore pulp opened in ceramic lined valve, when close during, in hard-hard extruding, easily cause ceramics
The workload for changing lining is arrheaed in lining fragmentation, increase.If ceramic lined valve need not be often closed in ore pulp flows in real time
Door can measure ore pulp weight concentration, when disabling with asking water to rinse, then can largely improve the survey of ore pulp weight concentration
Measure wear-resistant, anticorrosive, anti-clogging the ability of device.
Ultrasonic wave diver requires that pulp granularity distribution is relatively stable, to determine that the corresponding of doppler principle reflection is closed
System, size distribution is change in actual motion, and more metal ingredients and physical property are also continually changing, if in ore pulp
Also bubble, then it is more difficult to reflect this predetermined corresponding relation.And it is difficult to examine its accuracy in actual motion.
A kind of method also generally used both at home and abroad is down to weigh to measure pulp density determining volume premise.It is this
Method is with the characteristics of intermittence measures, it is necessary to which the volume of container is bigger under technique continuous flow, and factory building operating space has
Limit, even it is impermissible for using large-volume receptacle sometimes.If constantly changing container in measurement process, each container also only needs several
Minute will spill-over, it is big to pass in and out the open and close frequency of valve, easily grinds away, and if container without wear-resisting, corrosion resistant lubricous liner and suitable
Physical dimension be just difficult to clear ore pulp.Therefore ore pulp weight concentration is measured wear-resisting, corrosion resistant and be easy to ore discharge and miniaturization,
The problem of being urgent need to resolve.
Similar above-mentioned/gap the sample mode of volume method of weighing, at present also a kind of measuring method：Cylinder is from flow of slurry
Middle pumping sample（To avoid bulky grain from entering sampling blockage, blade sampling head is used in flow of slurry）, ore pulp flows through sample
Dispatch tube, filter screen are starched into the container of orthobaric volume, after scale is complete, slurries will return main technological process, and container will clean, screen cloth
Coarse granule will have respective handling measure.Although can also run, measuring system link is more, and maintenance workload is big, the upper and lower secondary time
Interval wants more than 10 minutes, can not actually realize on-line real-time measuremen very well, if slurry dispatch tube is longer, the time is longer, in real time
Poor performance, cause institute poor with addition of pharmaceutical quantities while property, and frequent, the easy jam of valve, pipeline is sampled for ore pulp.
Therefore many process industries requirements have it is a kind of can really in real time, the on-radiation of on-line continuous measurement slurry concentration it is small
Type detection means, the device adapt to ore pulp abrasion, block, corrode and can be vented bubble.
