Background technology
Flotation is also froth flotation, is the difference according to various mineral surfaces character, from ore pulp by means of the buoyancy of bubble, to select the process of minute mineral.At present, it is air jet flotation machine and mechanical stirring flotation machine that mineral processing in China Chang He coal preparation plant applies more flotation device, and the advantage of injecting type flotation power is that energy consumption is low, shortcoming is bad to pulp density applicability, and agitating device is not set, when pulp density is higher, what ore pulp mixed is short of power; The advantage of agitation impeller flotator is better to pulp density applicability, and shortcoming is that flotation efficiency is lower.
Impeller system is the most important operation element of agitation impeller flotator, is the heart of flow passage components, and it is comprised of cover plate and middle blade and stator.The direction flowing out from impeller according to liquid, that flotation machine impeller can be divided into is centrifugal, mixed-flow and 3 kinds of forms of axial-flow type.The performance quality of flotation device depends on the work of impeller system to a great extent, so one of the research emphasis of flotation device is exactly to flotation machine impeller systematic research.
And along with the increase of mine capacity, flotation device is to maximization future development, and the load of large flotation machines is larger, and it stirs power consumption and increases thereupon, this needs impeller to have more high mechanical properties, can produce the fluid dynamic state that is more suitable for flotation environment, and requires convenient for installation and maintenance.In addition from economic indicator angle, consider, as consumable accessory, the service life of impeller, the longer the better.
Utility model content
For above-mentioned prior art, the purpose of this utility model is to provide a kind of impeller system for agitation impeller flotator, and it is convenient for installation and maintenance, be more suitable for flotation environment, and long service life.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of impeller system for agitation impeller flotator, comprise cell body, it is characterized in that, in cell body, be provided with hollow central shaft, air intake duct, cover plate, impeller, mozzle, the impeller disk, described air intake duct is connected to described central shaft, is also provided with a main shaft in central shaft, fixing described cover plate and the impeller disk are installed in the lower end of main shaft, the impeller disk is positioned at cover plate, and the upper and lower surface of the impeller disk is provided with blade and lower blade, is that cell body bottom is provided with mozzle under the impeller disk.
In the utility model, the described impeller disk, blade and lower blade become by ultrahigh molecular weight polyethylene, this impeller disk is in the form of annular discs and to recessed song, on the impeller disk, be also provided with for installing the arc installing hole of blade and lower blade, the cross section of blade and lower blade is curved, radian is 20 °～50 °, and blade and lower blade are fixedly mounted on the impeller disk through arc installing hole.
The quantity of described blade and lower blade is respectively 6～10 pieces.
Compared with prior art, the utlity model has following beneficial effect:
