Its reserves of reproducible resource are being reduced year by year with swift and violent speed, and faced with this situation, utilization lean ore, tailing seem
It is particularly important that.In recent years, substantial amounts of research work has been carried out in this respect both at home and abroad, part scientific achievement has been applied to
In industrial production, good economy, environmental and social benefits are achieved.
Industrially developed country is horizontal and economically developed as a national science and technology is weighed using the degree of comprehensive utilization of tailing
The mark of degree, it is not only to pursue maximum economic effect using purpose, but also from comprehensive resource utilization rate, protecting ecology
The synthesis such as environment takes in.The comprehensive utilization of tailing research in China is started late, but is quickly grown in recent years, the metal in China
Mineral resources lean ore is more, Associated Constituents are more, middle-size and small-size mineral deposit is more, and many mines are exploited into middle and advanced stage at present, economic benefit day
Become reduce, situation forced some mines have to walk multi mineral product joint development and comprehensive utilization way.
The discharge of concentrate is to realize last link of FLOTATION SEPARATION, and on separate mode, flotation device uses edge more
The form of scraper plate scrapes bubble, and flotation column uses automatic Overruning more, these separate modes all largely accumulate there are foam, wait it is to be doctored
The residence time is long when going out, froth bed horizontal transfer stroke is big, there are the shortcomings of dead angle, not to froth concentrate active collection, all
The concentrate discharge mode of extensive style is may be considered, causes foam to accumulate, and then reduce concentrate collection efficiency and flotation efficiency.
The content of the invention

Embodiment
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Attached drawing describes in detail as follows：
Please refer to Fig.1 and Fig. 2, a kind of Qu Pao mechanisms on jet stream micro-bubble flotation machine, Qu Pao mechanisms 1 are installed on flotation
On the lower section pulp distributer mounting bracket 2-1 of the pulp distributer 2 of machine, including air duct 1-1, the center line of the air duct 1-1 with
The center line of flotation cylinder 3 overlaps, and the lower end of the air duct 1-1 is air inlet 1-10, and the upper end of air duct is sealed and installed with upper cover 1-
2, air outlet 1-20 is laid with the upper lid, the quantity of the air outlet is at least identical with the quantity of microvesicle mineralization unit 4,
When the quantity of air outlet is more than the quantity of microvesicle mineralization unit 4, no air outlet can be carried out in actual use close
Envelope closure, so that air duct has certain versatility；The microvesicle mineralization unit 4 includes being connected with above-mentioned ore pulp distribution pipe
Micro-bubble mineralizer 4-1, suction nozzle 4-2 is installed, the bottom connection mineralising of micro-bubble mineralizer is penetrated on the micro-bubble mineralizer
Flow tube 4-3, the bottom of the mineralising jet pipe extend to inner cylinder 5 through turbulence plate；The end connection of the mineralising jet pipe
Fluid jet nozzle 4-4；
The air outlet 1-10 connects the suction nozzle 2-2 on micro-bubble mineralizer 2-1 by pipeline respectively；For the ease of control
Intake, is provided with gate valve 1-3 on pipeline, and the air duct is interior to be provided with central shaft 1-4, central shaft along the axial direction of air duct
Center line overlapped with the center line of air duct；Axial flow fan leaf 1-5 is installed in air duct on central shaft；The central shaft 1-4's
Bottom is extended in the froth bed of 3 upper end of flotation cylinder formation；In the end of central shaft, installation, which is driven, carries concentrate particle
The drive bubble blade 1-6 that foam is moved horizontally to 6 direction of concentrate overflow launder, the bubble blade that drives is at least provided with five；Paddle is steeped when driving
When the quantity of leaf is very few, the driving force demand of bubble blade is driven with regard to big, when the power that air duct produces from bottom to top is not big enough, by nothing
The rotation of bubble blade is driven in method driving, and then is unable to reach the purpose for driving bubble；In order to ensure that foam is driving the drive of bubble blade as far as possible
Lower walking in a horizontal state, while avoid the driving force for driving bubble blade from damaging foam by pressure, the bottom for driving bubble blade 1-6 is located on flotation cylinder
It is more than flush or upper surface；In order to realize that adjusting intake in real time ensures to drive the driving force of bubble blade, in the air duct
Bottom be also equipped with adjust intake flashboard 1-7.
It is close in the bottom of the central shaft in order to make the trend that there is foam a horizontal direction concentrate overflow launder 5 to walk
Envelope is provided with pressure bubble guide shell 1-8, and bubble blade 1-6 is driven in the outer wall installation of the pressure bubble guide shell；The lower end of pressure bubble guide shell is set
There is deflection cone 1-9, the cone angle of the deflection cone is less than or equal to 45 °；The center line of deflection cone is overlapped with the center line of flotation cylinder 2.
The utility model drives Qu Pao mechanisms using the negative pressure of micro-bubble mineralizer suction nozzle, solves existing larger flotation
The problem of section foam accumulation, concentrate collection efficiency and flotation efficiency are improved, in addition, according to production bubble efficiency there is automatic adjustment to drive
The characteristics of steeping speed, driving force ratio is more steady during bubble is driven；Justing think can drive bubble blade to drive bubble using motor, but
The thickness for being the froth bed in floatation process is not a fixed state, and foam thickness is still used when foam layer thickness is smaller
Larger driving force is spent to carry out drive bubble, so will result in the rupture of effective foam, reduces flotation efficiency, mechanism and outer
Gas-distributing motor driving is compared to the loss for reducing effective foam, and this Qu Pao mechanisms do not consume other energy, have energy saving, emission reduction
Effect, while also reduce the manufacture cost of equipment, and the maintenance cost of equipment.
The above is only the preferred embodiment to the utility model, and not the utility model is made in any form
Limitation, it is every according to the technical essence of the utility model to any simple modification made for any of the above embodiments, equivalent variations with
Modification, belongs in the range of technical solutions of the utility model.
