In figure: 1, stirrer; 2, elutriation groove; 3, bend pipe; 4, bracket; 5, the bend pipe collar; 6, support; 7, rubber ring.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.

As shown in Figure 1, settling methods elutriation instrument of the present utility model, comprises support 6, and the elutriation groove 2 being supported on bracket on support 64 and being placed on support 6, bracket 4 connects the stirrer 1 that extends into elutriation groove 2; Elutriation groove 2 inside top is connected with the bend pipe collar 5 of two Relative distribution, the bend pipe 3 that the bend pipe collar 5 inner sleeve has to extend into elutriation bottom land end.

Wherein, elutriation groove 2 is cylindrical, and elutriation groove 2 diameter 20cm, is made by clear glass; Elutriation groove 2 inside top is connected with two relative bend pipe collars 5, the bend pipe collar 5 and elutriation groove 2 are linked together by glass material, the bend pipe collar 5 respectively has one in position diametrically, elutriation groove 2 top, and when damaging in order to one of them, elutriation groove can continue to use.Outside elutriation groove 2 from just to the bend pipe collar 5 times along place to elutriation groove 2 bottom high 25cm, be arranged on support 6.The bend pipe collar 5 height 1cm, diameter 1.2cm, the bend pipe collar 5 is dried up analyses groove 2 wall 0.5cm, and the bend pipe collar 5 and elutriation groove 2 are linked together by glass material.

Bend pipe 3 one end is the long end extending into elutriation groove, and long end bottom is provided with scale; Along being 0 point under long end, extending upwardly to 26cm, diameter 1cm, is transparent glass material.One end is short end, and short end end sleeve has flexible pipe.

Rubber ring 7 is enclosed within bend pipe 3 long end side, the thick 0.3cm of rubber ring 7, can people for sliding up and down rubber ring 7, to adjust bend pipe at any time the inserting degree of depth in elutriation groove 2.This instrument stirrer 1 speed of agitator can adjust between 0-2000r/min.

Shown in Fig. 2, above stirrer, be provided with control panel.

The settling methods wet elutriator using method that the utility model provides is as follows:

Weigh 50 ~ 200g material to be measured, be made into liquid-solid ratio be 6: 1 ~ 10: 1 ore pulp pour in elutriation groove.

Calculate the calculated settlement time as follows:

$t=\frac{h}{v_0}=\frac{h\mathrm{\μ}}{54.5d^2(\mathrm{\δ}-\mathrm{\ρ})}$

In formula: t is the settling time, unit s; H is settling height, unit cm; ν ₀for terminal velocity, cm/s; The coefficient of viscosity of μ water, normal temperature 0.01 is moored; χ is the spherical coefficient of material; D is lane particle diameter, unit cm; δ is material density to be measured, g/cm ³;

Rubber ring is adjusted to certain altitude, bend pipe is inserted in ore pulp by any one collar, read according to the scale of bend pipe the degree of depth h that bend pipe inserts ore pulp.

Opened by stirrer, adjustment impeller fully stirs ore pulp to suitable rotational speed, and ore particle is fully suspended.Stop starting writing time with stopwatch immediately when stirring;

After ore pulp standing sedimentation elapsed time t, utilizing bend pipe ore pulp siphon to be gone out, is the ore particle that granularity is less than d entirely in ore pulp.Be deposited in the precipitum in elutriation groove, also can some because of test error fail release the ore particle being less than d, in cup, add clear water again to original bend pipe scale place, then repeat step 3, four, five operations, until the liquid of releasing is no longer containing ore particle.

The liquid of releasing merged, filters, dry, weighing obtains being less than the grade weight of partition size d, when carrying out the analysis of n grade, calculate the time value needed for sedimentation respectively by a predetermined n partition size, from fine to coarse, carry out the operation of step 3 to five successively.

Above content is only the preferred embodiment of the utility model; can not assert that embodiment of the present utility model is only limitted to this; for the utility model person of an ordinary skill in the technical field in the technical scope that the utility model is conceived; can be made some simply deduce or replace, all should be considered as being encompassed within protection domain of the present utility model.
