Background technology
Coal is as China's main energy sources, and proportion is considerably long in future in primary energy production and consumption total amount
70% or so is will be maintained in period.To meet demand of the rapid economic development to the energy, mechanical coal mining technology is constantly pushed away
Extensively, coal mining amount increases year by year, and coal washing task is very arduous.At present, flotation be graded shot and superfine granule fine coal most
Ripe, effective method, and realized industrialization.However, as coal mining depth is constantly deepened, fine slime is in raw coal
Proportion persistently increases, in addition coal resources in China it is thin in itself, miscellaneous, it is difficult the characteristics of, and market to quality of cleaned coal require day
It is beneficial harsh, comprehensively cause particulate and micro-size fraction coal slurry content in float coal mud constantly to increase, coal slime floatability be deteriorated and be in into
One step degradating trend, slime separation effect difference and in the urgent need to efficient separation, utilize the contradiction between a large amount of coal slimes.
With the increase for entering particulate and micro-size fraction ratio in float coal mud, coal slime flotation process is proposed more to floatation equipment

Embodiment
The embodiment of technical solutions of the utility model is described in detail below in conjunction with accompanying drawing.Following examples are only
For clearly illustrating the technical solution of the utility model, therefore example is only used as, and this practicality can not be limited with this
New protection domain.
As shown in figure 1, as a kind of embodiment, flotation column provided by the utility model includes：Cylinder 1, gas
Steep generator 2 and ultrasonic probe 3.The top of cylinder 1 is provided with overfall 11, and side wall is provided with dog-house 12.Overfall 11
For the spilling of drainage material (cleaned coal), wherein in order to collect the material flowed out from overfall 11, the utility model is also in cylinder 1
Lateral wall collecting tank 4 is set, the drainage material flowed out from overfall 11 can fall directly into collecting tank 4 and be collected.Feed intake
Mouth 12 is used to deliver material to be sorted into cylinder 1.Air bubble generator 2 and ultrasonic probe 3 are respectively arranged in cylinder 1；
Air bubble generator 2 is used to produce the bubble risen in cylinder 1, and the bubble of generation can form froth bed on the top of cylinder 1, be
Realize that air bubble generator 2 can specifically be arranged at the bottom or the position close to bottom of the inner chamber of cylinder 1 by the effect.Ultrasonic wave
Probe 3 is used to provide the ultrasonic wave field of force, to shake the material formation in cylinder 1.In view of each material particles in assorting room
In be to be risen or fallen along the axis direction of cylinder 1, therefore in order to reach optimal concussion to material particles and scattered effect
Really, the ultrasonic probe 3 in the utility model should be set with the direction vertical with the material particles direction of motion, be surpassed in other words
Sonic probe 3 should be set along the radial direction of cylinder 1.
Because the ultrasonic wave field of force covering radius produced by ultrasonic probe 3 is limited, therefore in order to ensure in main body 1
It can be covered, should be taken measures respectively in the circumferential and axial of main body 1 respectively by the ultrasonic wave field of force everywhere, it is feasible
Scheme at least includes：
In the circumferential：At the sustained height of cylinder 1, visited by the multiple ultrasonic waves of axis annular array of the axis of cylinder 1
First 3 so that the ultrasonic wave field of force of multiple ultrasonic probes 3 covers the cross section of cylinder 1；Or at the sustained height of cylinder 1
One ultrasonic probe 3 is only set, but experiments verify that the length only when ultrasonic probe 3 in cylinder 1 is column diameter
At 0.25-1 times, the effect that the cross section of cylinder 1 is completely covered can be reached.
In the axial direction：Set multiple along axial direction (i.e. at the different height of cylinder) spacing of cylinder 1 is (preferably equidistant)
Ultrasonic probe 3.Experiment proves that, when by the line space design of the adjacent ultrasonic probe 3 of any two for 5-30cm, substantially
It ensure that the ultrasonic wave field of force that the plurality of ultrasonic probe 3 axially arranged along cylinder 1 is produced covers cylinder in the axial direction
Each position；And when by the line space design of the adjacent ultrasonic probe 3 of any two for 10-20cm, then any two is adjacent
Ultrasonic probe 3 produced by the ultrasonic wave field of force it is just non-overlapping or overlapping less, i.e. the ultrasonic wave field of force in cylinder 1 axially
On be evenly distributed, and then make it that the material particles in the cylinder 1 at different height are uniform by concussion, so as to be more conducive to sort
The progress of task.
Flotation column provided by the utility model is due to introducing ultrasonic probe 3, the ultrasonic wave of the formation of ultrasonic probe 3
The field of force can promote material particles scattered in flotation column, the probability of increase hydrophobic granule and bubble hit, attachment and adhesion,
Improve the rate of recovery of cleaned coal particle；The oscillation action of ultrasonic wave can strengthen bubble to the thin mud particle of mechanical entrapment or dredge simultaneously
The removing effect of aqueous weaker particle, is realized to the selected of material.
The method that sorting ore pulp is carried out using the utility model flotation column, is comprised the following steps：
A. air bubble generator 2 produces the bubble risen in cylinder 1；Start ultrasonic probe 3 so that ultrasonic probe 3
The ultrasonic wave field of force is formed in cylinder 1；
B. ore pulp to be sorted is delivered into cylinder 1 by dog-house 12；
C. ore pulp forms sorting under the comprehensive function of self gravitation, rising bubble and the ultrasonic wave field of force；Wherein in ore pulp
Hydrophobic granule rise with the bubble of rising, and eventually through overfall 11 flow out cylinder 1；Hydrophilic granules in ore pulp are certainly
The bottom of cylinder 1 is settled down under body Action of Gravity Field, tail coal product is formed.And in order to avoid tail coal product forms product in cylinder 1
Poly-, the utility model can set discharge gate 13 in the bottom of cylinder 1, so that tail coal product is when reaching 1 bottom of cylinder
It is discharged.Further, the bottom of cylinder 1 can also be designed as funnel-form, water conservancy diversion effect is formed with the discharge to tail coal product
Really.
Material is in the detailed process of cylinder formation sorting in above-mentioned steps c：
C1. the bubble generated by air Bubble generating apparatus 2 is moved upwards in cylinder 1, the bubble moved upwards and fortune downwards
Adverse current mineralising phenomenon occurs for dynamic ore pulp, and wherein hydrophobic granule adheres to bubble formation mineral laden bubble, and in bubble lifting action
Lower motion upwards, into the froth bed at the top of cylinder；Hydrophilic granules not with bubble adhesion, and be to continue with moving downward；So as to real
Hydrophobic granule and separation of the hydrophilic granules by particle are showed；
C2. the mineral laden bubble in froth bed is entered under the secondary enrichment comprehensive function in the ultrasonic wave field of force and froth bed, foam
The gangue particle of mechanical entrapment, the particle weaker with bubble adhesion come off from bubble and moved downward, and strong with bubble adhesion
Hydrophobic granule is continued up, and finally enters collecting tank 4 with foam overflow, forms overflow product (head coal product)；
C3. the particle come off from bubble during moving downward,
Or adhered to again with the bubble that moves upwards, repeat the above steps c1 and c2；
Or move downward, and with the bottom that not collecting with the hydrophilic granules of bubble adhesion into the inner chamber of main body 1 in ore pulp
Portion, and it is final from the discharge cylinder 1 of discharge gate 13 inner chamber, form tail coal product.
