Abstract
The utility model relates to a complicated-terrain long-distance pipeline-conveying ore slurry particle-size monitoring device, which is characterized in that: a particle-size monitoring instrument is respectively arranged at a pipeline entry and a pipeline exit of an ore slurry conveying pipeline. By calculating a ratio between the distribution value of each self-counted particle size at the pipeline exit and the distribution value of each self-counted particle size at the pipeline entry, the situation that whether solid rough particles inside the ore slurry pipeline are precipitated can be known at any time, so the water pressure inside the conveying pipeline can be further adjusted, and the precipitation can be avoided.
Description
Technical field
The utility model relates to a kind of monitoring device of delivering pipe safe operation, especially relates to a kind of complex-terrain long-distance line transportation ore pulp particle diameter monitoring device.
Background technique
Solid material length is apart from the ore slurry pipeline course of conveying, and solid ore pulp particle diameter is through under the effect of waterpower, pressure and phase mutual friction, and its size changes to some extent, and this changes the erosion corrosion that directly influences pipeline.
And, under the low excessively situation of slurry flow velocity, can cause the solids crude particle in the ore pulp to be trapped in the pipeline, do not handle then for a long time and can cause line clogging, have a strong impact on the safe and stable operation of pipeline.
Summary of the invention
The utility model has designed a kind of complex-terrain long-distance line transportation ore pulp particle diameter monitoring device, and the technical problem of its solution is:
(1) the solid ore pulp coarse granule footpath during ore slurry pipeline is failed is under the effect of unsuitable waterpower, pressure and phase mutual friction, and its size changes to some extent, can directly influence the erosion corrosion of pipeline;
(2) the pulp solids coarse granule footpath during ore slurry pipeline is failed is under the effect of unsuitable waterpower, pressure and phase mutual friction, and the solids crude particle is trapped in the delivering pipe easily.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of complex-terrain long-distance line transportation ore pulp particle diameter monitoring device is provided with a particle diameter monitor respectively at the entrance place and the pipeline exit of ore pulp delivering pipe.
Further, described particle diameter monitor is monitored described ore pulp particle diameter by laser.
This complex-terrain long-distance line transportation ore pulp particle diameter monitoring device has following beneficial effect:
(1) the utility model is owing to count the ratio that particle size distribution and entrance place ore pulp are counted the particle size distribution value separately separately by calculating the pipeline exit ore pulp, thereby can learn at any time whether solids crude particle in the ore slurry pipeline exists the situation of deposition, thereby can further regulate the hydraulic pressure in the delivering pipe, avoid the generation that deposits.
(2) the utility model is by the change of size of starting point in the monitoring analysis long-distance pipe running and destination county, can carry out dynamic monitoring to whether being detained the coarse granule ore pulp in the pipeline, whether ore pulp is all carried in the monitoring pipe conveying procedure, has avoided the coarse granule ore pulp can be to the erosion corrosion of pipeline.
(3) the utility model is counted the ratio that particle size distribution and entrance place ore pulp are counted the particle size distribution value separately separately by calculating the pipeline exit ore pulp, can calculate and definite ore pulp in best coarse granule diameter, handle by the coarse granule diameter in the ore pulp being carried out optimization, make ore pulp as much as possible all by the ore pulp delivering pipe.
Description of drawings
Fig. 1 is the structural representation of the utility model complex-terrain long-distance line transportation ore pulp particle diameter monitoring device.
Description of reference numerals:
1-ore pulp delivering pipe; 11-entrance place; The 12-pipeline exit; 2-particle diameter monitor.
Embodiment
Below in conjunction with Fig. 1, the utility model is described further:
A kind of complex-terrain long-distance line transportation ore pulp particle diameter monitoring device comprises two particle diameter monitors 2, and these two particle diameter monitors 2 are separately positioned on entrance place 11 and the pipeline exit 12 at ore pulp delivering pipe 1.
The monitoring method and the working principle of this complex-terrain long-distance line transportation ore pulp particle diameter monitoring device are as follows, may further comprise the steps:
At first, entrance place 11 and the pipeline exit 12 at ore pulp delivering pipe 1 is provided with a particle diameter monitor 2 respectively;
Secondly, open two particle diameter monitors 2 of ore pulp delivering pipe 1 and entrance place 11 and pipeline exit 12;
Best, the particle diameter monitor 2 that is positioned at entrance place 11 records entrance place ore pulp and counts the particle size distribution value separately, and the particle diameter monitor 2 that is positioned at pipeline exit 12 records the pipeline exit ore pulp and counts the particle size distribution value separately, even if both are carried out following ratio:
Wherein,
T1 is an entrance place ore pulp particle diameter monitoring time starting point;
T2 is an entrance place ore pulp particle diameter monitoring time terminal point;
Φ (t) is the time dependent distribution function of entrance place ore pulp particle diameter;
Ψ (t) is the time dependent distribution function of pipeline exit ore pulp particle diameter;
When the pipeline exit ore pulp is counted particle size distribution separately the ratio of several particle size distribution is 1 separately with entrance place ore pulp, represent ore pulp all to pass through pipeline;
When the pipeline exit ore pulp is counted particle size distribution separately the ratio of several particle size distribution is 0 separately with entrance place ore pulp, represent ore pulp all not pass through pipeline;
When the pipeline exit ore pulp count separately particle size distribution and entrance place ore pulp separately the ratio of several particle size distribution be greater than 0 less than 1 the time, represent ore pulp partly to pass through pipeline.
This particle diameter monitor 2 is monitored described ore pulp particle diameter by laser.
This monitoring method has the following advantages:
(1) the utility model is owing to count the ratio that particle size distribution and entrance place ore pulp are counted the particle size distribution value separately separately by calculating the pipeline exit ore pulp, thereby can learn at any time whether solids crude particle in the ore slurry pipeline exists the situation of deposition, thereby can further regulate the hydraulic pressure in the delivering pipe, avoid the generation that deposits.
(2) the utility model is by the change of size of starting point in the monitoring analysis long-distance pipe running and destination county, can carry out dynamic monitoring to whether being detained the coarse granule ore pulp in the pipeline, whether ore pulp is all carried in the monitoring pipe conveying procedure, has avoided the coarse granule ore pulp can be to the erosion corrosion of pipeline.
(3) the utility model is counted the ratio that particle size distribution and entrance place ore pulp are counted the particle size distribution value separately separately by calculating the pipeline exit ore pulp, can calculate and definite ore pulp in best coarse granule diameter, handle by the coarse granule diameter in the ore pulp being carried out optimization, make ore pulp as much as possible all by the ore pulp delivering pipe.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or design of the present utility model and technological scheme are directly applied to other occasion without improving, all in protection domain of the present utility model.
