The wetelutriator is structured by comprising a water analyzing groove, an overflowing port, a sand sinking port, a ruler and a supporting frame; the water analyzing groove is circular; the ruler is arranged on the side surface of the water analyzing groove; the overflowing port is arranged at the lower part on the side surface of the water analyzing groove; the sand sinking port is arranged in the middle of the bottom of the water analyzing groove; and the water analyzing groove is mounted on the supporting frame. The wetelutriator provided by the utility model is simple in structure, convenient to operate, less in measurement error, high in measurement efficiency, and capable of conveniently paying the important role of the hydraulic power analysis in scientific search and production.
Description
Technical field
The utility model belongs to ore dressing field, relates to a kind of elutriation method wet elutriator that carries out hydraulic analysis.
Background technology
Hydraulic analysis is the method that forms by the settling velocity indirect measurement raw meal particle size of measuring particle, is commonly used to replace sizing analysis to measure the size composition of Separate Fine-grained Minerals, widespread use in ore dressing research and production.By contrast, the elutriation method elutriation is used the most common.
At present elutriation method and elutriation device thereof commonly used adopts siphonage sucking-off suspending liquid, has operation inconvenience, and fluctuation of service, the shortcoming such as measuring error is large, Measuring Time is long have affected its application in scientific research and production.
The utility model content
The utility model provides a kind of elutriation method wet elutriator, can carry out hydraulic analysis to material efficiently and accurately.
The elutriation method wet elutriator structure that the utility model provides comprises:
Elutriation groove, overflow vent, spigot, scale and carriage, the elutriation groove is rounded, and the side is provided with scale, and overflow vent is located at bottom, elutriation groove side, and spigot is located at elutriation trench bottom centre position, and the elutriation groove is installed on the carriage.
Described scale under the overflow vent opening along 0 point as the sedimentation absolute altitude, scale take cm as basic unit mm for inferior unit extends upward, until 240mm.
Described overflow vent is located at 85mm place at the bottom of the useful space, bottom, elutriation groove side.
The elutriation method wet elutriator using method that the utility model provides is as follows:
One. weighing 50～200g material to be measured, the ore pulp that is made into liquid-solid ratio and is 6: 1～10: 1 is poured in the elutriation groove, then adds clear water to the 10-24cm height;
Two. calculate as follows the calculated settlement time
In the formula: t is the settling time, the s of unit; H is settling height, the cm of unit; ν
0Be terminal velocity, cm/s; μ is the coefficient of viscosity of water, normal temperature 0.01 pool; χ is the spherical coefficient of material; D is the critical particle diameter, the cm of unit; δ is material density to be measured, g/cm

Three. fully stir ore pulp, ore particle is fully suspended.Record the time with stopwatch immediately when stopping to stir;
Four. ore pulp standing sedimentation elapsed time t, open surplus valve and emit fluid or ore pulp, be that granularity is less than the ore particle of d entirely in the ore pulp.Be retained in the precipitum in the elutriation groove, also can some ore particle less than d of failing to emit, in cup, add clear water again, then repeating step three and five operations are until the liquid of emitting no longer contains ore particle;
Five. will emit liquid merge, filter, dry, weighing obtains grade weight less than partition size d, when carrying out the analysis of n grade, calculate respectively the required time value of sedimentation by n predetermined partition size, from fine to coarse, carry out successively the operation of step 3 to five;
Six. after finishing last classification, open the sand setting valve and emit precipitum in the elutriation groove, rinse well, filter, dry, weigh, obtain the grade weight greater than partition size d, finally obtain the size composition (d of this sample
