Description
Technical field
The utility model relates to mining machinery field, specifically refers to the maximum gravity flow of a kind of tailing cemented filling material slurry times line determinator.
Background technology
Mine tailing cemented filling, adopts last mortar and cement after mix and blend, to be delivered to underground stope by pipeline self by a certain percentage more.Pipeline self delivery technology, is to arrange that a vertical pipeline is to underworkings, then arranges that horizontal pipe is to stope, slip relies on the discrepancy in elevation of earth's surface and underground stope, provides energy, for overcoming the energy consumption of full pipe conveying procedure resistance by slip gravitional force.In the time overcoming the required energy consumption of resistance the gravitional force that can provide is provided, slip cannot complete gravity flow; In the time overcoming the required energy consumption of resistance the gravitional force that can provide is provided, slip flow velocity is accelerated, and the perpendicular straight section height of slip is declined, and potential energy reduces, until overcome the required energy consumption of resistance and gravitional force equates; And when overcoming the required energy consumption of resistance and gravitional force and equating, slip is in equilibrium state, slip vertically section is highly stable, no longer changes.
In filling in mine process, for ensureing that Quality of filling body reduces down-hole dehydrating amount, need provide Filling density, but too high concentration will cause slip to flow automatically, and occur plugging as far as possible, produce thereby impact is normal.Therefore before filling, need to measure the maximum gravity flow times line of different mixture ratio, concentration slip, gravity flow times line is pipeline total length and the vertical ratio of the section discrepancy in elevation, and maximum gravity flow times line is the maximum pipeline total length that can flow automatically smoothly of slip and the vertical ratio of the section discrepancy in elevation.
Tradition assay method adopts collar experiment method more, and the method provides slip pressure by pump, and slip is carried out to pumping, and the pressure differential between 2 of testing conduits is measured the pressure loss of slurry pipeline transport process, then calculates the maximum gravity flow times line of slip by theory.Collar experiment need to be set up large-scale experiment system, and needing to arrange to provide the discharge pump of steady pressure, and the equipment such as the high pressure transducer of progress, need to take larger place, consume a large amount of test materials, testing complex, test period are long, and experimentation cost is high.
Utility model content
The utility model object is to provide a kind of test simple and fast, and conclusion is tested the device of the maximum gravity flow of tailing cemented filling material slurry times line intuitively.Occupied ground is little, saves test material, and the test period is short, and cost is low.
The utility model object is to realize like this, the maximum gravity flow of this tailing cemented filling material slurry times line determinator, comprise slurry pipeline transport pipe, receiving cone, receiving cone is installed on slurry conveying pipeline, described slurry pipeline transport pipe vertically on section sidewall every one end apart from measuring tube has been installed, measuring tube connects by measuring valve and described slurry pipeline transport pipe.
Described slurry pipeline transport pipe caliber is 8～2 times of measuring tube calibers.
On described slurry pipeline transport pipe, be carved with scale mark.
On described measuring tube, be carved with scale mark.
Due to described slurry pipeline transport pipe vertically on section sidewall every one end apart from measuring tube has been installed, measuring tube connects by measuring valve and described slurry pipeline transport pipe, slip relies on vertically section gravitional force to overcome the energy consumption in pipe conveying procedure, in the time that the energy consumption of slip gravitional force and course of conveying equates, observe after slurry outlet fluid stable, now and can measure the level balance height H of slip.Measuring principle is according to U-shaped pipe principle, and delivery pipe and measuring tube connect, and the liquid level of both slips is identical.For avoid the existing equilibrium state of disturbance delivery pipe in measuring process as far as possible, adopt many measuring tubes, and caliber is much smaller than delivery pipe, in operating aspect, before the interior material level balance of delivery pipe, measuring tube valve Close All, in the time starting to measure, open in turn measuring tube valve from top to bottom, there is slip position until have in a measuring tube, above test unit and test method have guaranteed that delivery pipe inner equilibrium state is measured in the situation of disturbance hardly, and have ensured that measuring accuracy is in controlled range.This kind of method also avoided the problems such as slip contaminated walls causes that reading is forbidden.The utility model is simple and easy reliably, conclusion is directly perceived, floor area is little, saves test material, and the test period is short, and cost is low.
