Background technology
Tailings paste disposal technology has huge environmental and social benefits, is a main development direction of futurity industry waste utilization.The feature of lotion is not emanate, do not precipitate, do not dewater, and only has when reaching when gathering materials or approaching saturation concentration, and aggregate void is filled up by moisture just, and gathering materials under this concentration just can possess these characteristics.
According to the applicant understood, lotion concentration defines other indexs such as mainly depending on yield stress, bleeding rate and indirectly tries to achieve.But yield stress is along with the difference that mine tailing grade forms differs larger, and in lotion concentration range, yield stress changes greatly; Country does not also put into effect full tail lotion bleeding rate and measures correlation test standard, for particle diameter at 1um the full tail of particulate to hundreds of um, when its concentration is higher, bleeding is slower, and slip is immersed in water, even through the sufficiently long bleeding time, the moisture between particle still has, so measurement result is inaccurate.
Also have scholar from the unit weight that forms lotion and gather materials and proportion to counter the pushing away of lotion saturation concentration theory, unit weight is difficult to accurate measurement, causes theoretical saturation concentration and the physical presence different calculating.The application of lotion technology is very responsive for concentration index, often the difference between high concentration and lotion is just at 2～3 percentage points, cause theoretical saturation concentration value effectively to deep wimble thickener underflow density, not instruct, cause the lotion concentration that is applicable to commercial Application to be difficult to fast quantification, and then hindered the development of lotion theory and lotion technology.
At present, also do not find the device that a kind of simple method can directly be measured lotion saturation concentration.For this reason, be necessary to seek novel lotion measurement mechanism and method, can be fast, Measurement accuracy lotion saturation concentration, for the operation of lotion technology thickening equipment provides theoretical foundation.
Utility model content
The purpose of this utility model is, a kind of novel lotion saturation concentration measurement mechanism and method are provided.The method can overcome traditional saturation concentration and solve slower or inaccurate defect, for the reasonable underflow density of deep wimble thickener provides engineering advice.Mainly contain following advantage: the first, device is drawn materials conveniently, and cost is low, simple to operate, can quick and precisely differentiate lotion saturation concentration; The second, measuring method is ingenious, and device is laid on mesh top by double-deck medical yarn, has both avoided mine tailing to flow out from mesh or has stopped up mesh, does not affect again moisture and leaches from mesh; The 3rd, for filtrate in mesh, adopt ultrawhite filter paper to accept, to leaching water droplet quality, quantize, further improved measuring accuracy; The 4th, whole device adopts organic glass to make, and adopts to fix to be connected with nested mode between different assemblies, is convenient to disassembly, cleaning, and Stability Analysis of Structures is sturdy and durable; The 5th, differentiation for lotion concentration is directly to measure, evaded the necessary deficiency that relies on other physical parameters such as unit weight of saturation concentration prediction, met the qualified lotion concentration of bargh and differentiate, thereby test comparatively reliably criterion for tailings paste concentration in industry provides.
The utility model main body is by testing base 1, ultrawhite filter paper 2, dripping and observe cylinder 3, back up pad 4, drainage mesh 5, connecting cylinder 6, double-deck medical yarn 7, tube for feed 8, stirring rod 9 form, as shown in Figure 1.
Back up pad 4 is fixed on the top of the observation cylinder 3 that drips, drainage mesh 5 is uniformly distributed in back up pad 4, connecting cylinder 6 is positioned at back up pad 4 tops, and fix with it, double-deck medical yarn 7 is smooth is laid on back up pad 4 surfaces, and tube for feed 8 is embedded in connecting cylinder 6 inner sides, and medical yarn 7 is pushed down, stirring rod 9 is used for stirring mine tailing, and moisture is coordinated interpolation with buret by graduated cylinder.
Ultrawhite filter paper 2 is placed in experiment base 1 upper surface, and ultrawhite filter paper is different according to tailings grade, lays the number of plies at 5～8 layers, when tailings grade is thicker, spreads more, when particle is thinner, can spread less.The Main Function of ultrawhite filter paper is the deficiency that makes up the moment inconvenience observation of dripping, even without seizure, drip moment like this, also can try to achieve the weight of dripping by the increase of filter paper weight, make measurement result more accurate, filter paper moisture oozes out also and can be accepted by experiment base, therefore, this kind of design guaranteed measuring accuracy.The polycrystalline substance of experiment base 1 constituent apparatus together with ultrawhite filter paper 2.
The observation cylinder 3 that drips is pressed in ultrawhite filter paper 2 tops, and be mainly used in observed drop and drip moment, this bottom hollow out, top hollow out, is made by organic glass.Bottom hollow out is mainly to facilitate water droplet to drop on filter paper, simplification device structure.Inside diameter ranges is 5cm～8cm, and height is 8cm～12cm, and the selected relatively high height of the observation cylinder that drips is to be mainly convenient to observation in order to drip.
Back up pad 4 is fixed on observation cylinder 3 tops of dripping, and mainly plays the effect that top tailings stirs of supporting, and its diameter is identical with observation cylinder 3 external diameters that drip.Why like this design, mainly contains two reasons, and the one, be convenient to processing, the 2nd, device is more durable.
Connecting cylinder 6 is positioned at the top of back up pad 4, and fixes with it, and so far, drip observation cylinder 3, back up pad 4 and connecting cylinder 6 are fixed together, the substructure of constituent apparatus.The Main Function of connecting cylinder 6 is that tube for feed 8 is connected with substructure.The internal diameter of connecting cylinder 6 is consistent with the observation cylinder 3 that drips, and scope is 5cm～8cm, and it is highly 4cm～6cm.
Double-deck medical yarn 7 is laid in is with meshed back up pad 4 upper surfaces, before tiling, by medical yarn water-soaked, then wrings out, and reduces cotton yarn as far as possible and absorbs the experimental error that in lotion, moisture causes.Because cotton yarn area is less, therefore, even if water absorbing capacity has, also very little.Double-deck medical yarn 7 major functions, for stoping tailings in tube for feed 8 to run off from drainage mesh 5, guarantee in lotion that excessive moisture effectively oozes out simultaneously, and then drip by mesh 5.
Tube for feed 8 is embedded in connecting cylinder inner side, and double-deck medical yarn 7 is pushed down.Therefore tube for feed 8 external diameters are all 5cm～8cm mutually with connecting cylinder 6 internal diameters, and between the two, guarantee the spacing of 1mm～2mm, leaving hole is that double-deck medical yarn redundance is extended out from hole, makes double-deck medical yarn 7 be difficult for misplacing in tailings whipping process.Because tube for feed 8 bottoms have 4 pairs of back up pads to stir tailings, support, so tube for feed 8 does not need base.Height is 10cm～16cm, and why internal diameter is chosen than highly little a lot of reason, is mainly to want to make non-saturated area, top controlled, reduces non-saturated area area as far as possible.
Stirring rod 9 major functions are for slowly evenly adding water, drainage and beating action.Stirring rod adopts stainless steel to make, and frangibility, can fully not stir, and its diameter is 5mm～10mm, and length is 1.5～1.8 times of bucket 8 height.
That the utility model is made is simple, conveniently moving, non-power consumption, adopts the method for directly measuring lotion concentration to predict qualified lotion concentration, more convenient to use, ageing better.Have that cost is low, simple to operate, method is ingenious, the advantages such as reliable results, can measure a certain tailings paste saturation concentration within a short period of time, evade saturation concentration prediction and must rely on the deficiency that other physical parameters such as unit weight are carried out theoretical calculating, meet the qualified lotion concentration of bargh and differentiate demand, be applicable to the mine tailing of the various barghs size fractionated scopes such as coloured, noble metal, rare metal, gold, uranium ore.
