Description
Technical field
The invention belongs to flotation technology field, more particularly to one kind is applied to laboratory flotation column or the sorting of other pillars sets
Back-up selects the method and apparatus of sample synchronous acquisition in process middle column body.
Background technology
The mineral resources of China are wide in variety, and skewness weighing apparatus, lean ore is more, and rich ore is few.With the high speed of Chinese national economy
Development, the extensive the exploitation mode of tourism resource of " exploitation high, low utilization, maximum discharge " necessarily causes mineral resources scarcity, energy shortage
And environmental pollution, the exploitation of mineral resources, using facing huge challenge.For the processing sorting of mineral, it protrudes special
Point is that low-grade ore increases, and, disseminated grain size complicated with the embedding cloth relation of other mineral is thin and uneven, and hardly possible selects the ratio with extremely difficult ore dressing
Example increase.In this context, flotation column shows because of its sorting advantage to Separate Fine-grained Minerals high selectivity in flotation technology field
Powerful vitality, is increasingly paid attention to by ore dressing circle, and many countries have carried out numerous studies work.
In the research of flotation column, the sorting behavior for disclosing heterogeneity mineral grain in post floatation process middle column body is one
Individual important research direction, for the separating effect for improving flotation column, optimization operation, improvement column structure is significant.
As can be seen here, realize to the real-time of different spatial sample, synchronous and precise acquisition in flotation column process middle column body extremely
Close important.At present, in laboratory conditions, it has been disclosed that flotation column cylinder in sample acquisition method it is few.Most viable side
Method is the side-wall hole in different height of column, is inserted into suitable sampling pipe, when collection sample is needed by sampling pipe
Collection sample.But, due to flotation column during, the property of different height of column ore pulps is different, and cylinder bottom is ore pulp
Area, cylinder top be froth zone, and ore pulp area in also contain a large amount of bubbles, therefore, by sampling pipe gather sample when, it is difficult to adopt
Collection froth pulp, it is impossible to ensure accuracy, the representativeness of sampling.What is more important, in this method of sampling, gathers sample
When can produce influence on the assorting room of flotation column, especially sampled point quantity is more and during multiple sampled point synchronized samplings, samples
Influence of the journey to flotation column process is more obvious, cannot more ensure to gather the accuracy of sample.At present, on laboratory
The method and apparatus of different spatial synchronized sampling has no report in flotation column process middle column body.
The content of the invention
To overcome the deficiencies in the prior art, synchronously adopted it is an object of the invention to provide sample in a kind of laboratory flotation column
Acquisition means and method, the device and method do not interfere with the assorting room of pillar screening installation, and ensure that foam or slurry are equal
Can smoothly take out, can also realize that different spatial is sampled simultaneously in cylinder, it is ensured that the representativeness and synchronism of sample.
To achieve the above object, the technical solution adopted by the present invention is：
Sample synchronous acquisition device in a kind of laboratory flotation column, including cylinder, are in series with several separator valves on cylinder
Door, separating valve is used to connect or separate cylinder；Each to separate and be provided with probe tube on the side wall of the cylinder above valve, samples
Sample cock is housed, probe tube is used to take out the sample in cylinder on pipe.
Further, the separation valve is ball valve, and the latus rectum for separating valve is identical with the internal diameter of cylinder.
Further, the cylinder connects into an entirety by multiple flanges.
Further, the cylinder is fixed on runing rest；Runing rest is fixed on base by connecting rod, rotation
Support can be around connecting rod 360 ° of rotations in the horizontal direction.
Based on said apparatus, the invention allows for sample synchronous collection method, technical side in a kind of laboratory flotation column
Case is as follows：
Sample synchronous collection method in a kind of laboratory flotation column, when needing to gather the flotation column that a certain moment is currently running
During interior sample, the space in flotation column simultaneously, is quickly divided into some samplings for being spaced, sealing first according to sampling request
Interval, and stop flotation column operation simultaneously；Then the sample in different sampling intervals, as synchronization are sequentially or simultaneously taken out
It is distributed in the sample of different spatial in cylinder.
Beneficial effect：Sample synchronous acquisition device and method in the laboratory flotation column that the present invention is provided, with following excellent
Point：
(1) sampling process is separate with the assorting room of column type equipment, it is to avoid sampling process is to equipment assorting room
Influence, it is ensured that the accuracy of collection sample with it is representative.
(2) collection of any property sample such as foam or ore pulp is applicable to, the post of araeosystyle screening installation is improve
The feasibility and reliability inside sampled.
(3) it is capable of achieving to the synchronous acquisition of different spatial sample in post, obtains any in column type equipment assorting room
The real distribution situation of material in moment post, realizes the Real-time Collection to sample in post.
