Description
Technical field
The invention belongs to metallurgical and mine ore dressing technical field, it is related to a kind of high-concentration tailings ore pulp continuous sampling system.
Background technology
Metallurgical and Mineral Processing Industry reduces the damage that useful metal is lost in tailing to obtain the more preferable mine resources rate of recovery
Lose, advanced online grade analysis system has mostly been introduced, for the content of useful metal in on-line analysis tailing ore pulp, scene
Operating personnel are according to these analysis data, real-time adjusting process parameter and dosing configuration, so that the more preferable rate of recovery is obtained, to subtract
The loss of few useful metal.But there are the following problems in use at the scene for online grade analysis system, small with Luanchuan dragon space molybdenum industry
Exemplified by Miao Ling ore dressings company, the ore dressing field through it is last scan together flow to after technique tailings concentration in thickener for 45%~
50%, belong to high concentration ore drawing；But the sample point of tailing ore pulp is on the underflow pipeline after finally scanning technique together, is somebody's turn to do
Sample point is apart from about 60 meters of the pipeline distance of online grade analysis system, about 9 meters of vertical range；Along with online grade analysis system
Unite smaller to sampling the ore pulp demand of ore pulp, generally 6m3/h.So the sample point belongs to typical high concentration, long distance
From, small flow, high-lift sample point.Make taken high-concentration ore slurry sample in remote, small flow, high-lift course of conveying
In, easily precipitate, cause line clogging, cause online grade analysis system can not provide the analysis data of continuous-stable,
And dredging pipeline is required for spending substantial amounts of man power and material every time.
In order to solve above problem, inventor is by carrying out Luanchuan Area relevant industries widely investigation and to score
Analysis, has following two for the taken method that solves the above problems at present：
First method is that dilution buffer pond is arranged on to the lower section of sampler, then coordinates pipe with small pipe diameter by slag slurry pump under liquid
Pipeline is by tailing pulp conveying to online grade analysis system.But in actual moving process, it is defeated since pulp density is larger
Send distance longer, the gradient of pipeline is smaller, smaller etc. the factor of ore pulp flow, causes pipeline at least to block more than 3 times daily,
It is required for 3~4 hours of several personal costs to dredge after each line clogging, so neither can guarantee that continuous sampling, together
When waste manpower.
Second method is that the above and below of sampler is set dilution buffer pond, the dilution buffer pond of top respectively
It should be higher than that online grade analysis system, lifted the ore pulp in the dilution buffer pond below sampler to upper by slag slurry pump under liquid
In the dilution buffer pond of side, then by pipeline self into online grade analysis system.But in actual moving process, by
In the limited height of workshop, so the gradient of pipe gravity flow pipeline is smaller, easily block, meanwhile, pipeline is positioned at high aerial, installation, dimension
Repair, heavy workload relatively difficult with upkeep operation.
