Abstract
The utility model relates to a device for measuring the cycle medium viscosity during a heavy medium coal preparation process and the suspension solid particle settlement velocity during a suspension transportation process of a pipe, in particular to a device for directly measuring the suspension solid particle settlement velocity. The utility model includes a vertical pipe section and two differential pressure densitometers. The lateral wall of the vertical pipe is equipped with a sampler. The lower part of the sampler is equipped with the two differential pressure densitometers, which are connected in serial. And a fixed vertical height difference is arranged between the two differential pressure densitometers. Compared with a medium viscosity estimation method by measuring coal slime content, the device directly calculates the suspension solid particle settlement velocity by measuring the difference between density signals sent out by two densitometers. Therefore, the device has the advantages of simple structure, convenient installation and use, good stability and high measurement precision.
Description
Technical field:
The utility model relate to be used for heavy medium coal preparation process to the measurement of circulatory mediator viscosity and in pipeline transportation suspending liquid process the measurement mechanism of suspending liquid solid particles sediment speed, especially a kind of device of direct measurement suspending liquid solid particles sediment speed.
Background technology:
Recently dense-medium separation development is very fast, and is very big to the coal separation influential effect in heavy medium coal preparation process medium viscosity, can directly not be used for the industrial instrument of measuring media viscosity but up to the present also have.In order to estimate dielectric viscosity, present industrial employing densitometer and the combination of ferromagnetism thing content meter are measured union roughly and are gone out what of coal slurry content in the medium, with this parameter estimation dielectric viscosity.This method error is very big, can not be as the direct control medium viscosity of control signal, and can only be as a reference.In addition, suspending liquid solid particles sediment speed also is extremely important technological parameter in pipeline transportation suspending liquid process, monitors extremely important to this parameter.At present also there is not directly to measure the industrial instrument of this parameter.
Summary of the invention:
In order to solve the described deficiency of above-mentioned background technology, the utility model provides the device of a kind of simple in structure, easy to install, good stability, direct measurement suspending liquid solid particles sediment speed that measuring accuracy is high.
The technical solution adopted in the utility model is: a kind of device of direct measurement suspending liquid solid particles sediment speed, comprise one section vertical pipe, two differential density meters, on the described vertical pipe sidewall sampler is housed, two differential density meters of the fixed vertical discrepancy in elevation are equipped with and are connected in series, had in this sampler bottom between the two.
The utility model with adopt to measure coal slurry content and how much estimate that the method for dielectric viscosity compares, owing to be with the use of vertically connecting of two differential density meters, and MEDIA FLOW to cross densitometric flow velocity be constant relatively, therefore two density signals that densitometer sent are differentiated up and down, following density signal can be greater than the density signal of top, both differences are very little, and it and suspending liquid solid particles sediment speed exist corresponding relation.The big more expression suspending liquid of this difference solid particles sediment speed is big more, and stability is poor more; Difference is more little, shows that suspending liquid solid particles sediment speed is more little, and stability is good more.So this device directly obtains can draw after this difference the settling velocity and the density of suspending liquid solid particle, in process of production, this value is controlled in optimum range, both can guarantee that technological parameter is normal, can guarantee than high efficiency again.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
A kind of device of direct measurement suspending liquid solid particles sediment speed, form by vertical pipe 1, sampler 2, A point differential density meter 3, B point differential density meter 4, flow nipple 5, on this vertical pipe 1 sidewall sampler 2 is housed, these sampler 2 bottoms are by the fixed vertical discrepancy in elevation, install A point differential density 3 and B point differential density 4 respectively in series system, these B point differential density meter 4 lower ends be equipped with vertical pipe 1 together with flow nipple 5.
The measuring principle of this device is as follows:
In vertical pipe 1,, then there is corresponding relation in the A of the fixed vertical discrepancy in elevation, the density difference of B point-to-point transmission and the settling velocity of suspending liquid because the flow velocity of suspending liquid is substantially invariable.As represent the density of 2 of A, B respectively with ρ a and ρ b, with A point differential density meter 3 and B point differential density meter 4, measure ρ a and ρ b respectively, use again that (a) * Kv=V is as settling velocity signal (wherein Kv is a transfer function to ρ b-ρ), and the density difference of B, A point-to-point transmission multiply by the solid particles sediment speed V that Kv just becomes tested suspending liquid.Like this with regard to available ρ a, ρ b and (ρ a+ ρ b) as density signal, with the settling velocity signal of V, directly measure the settling velocity and the density of suspending liquid solid particle as measured medium.
