Description
Technical field
The present invention relates to a kind of cyclone, and in particular to the centrifugal cyclone device of idetified separation.
Background technology
Cyclone is a kind of common separation classifying equipoment, commonly uses centrifugal sedimentation principle.When two-phase mixtures liquid to be separated
After tangentially entering in cyclone from cyclone periphery with certain pressure, the strong rotational shear turbulent flow fortune of strong Three-Dimensional Elliptic is produced
It is dynamic.Poor due to there is granularity between coarse granule and fine grained, it is subject to centrifugal force, centripetal buoyancy, fluid drag etc. of different sizes,
Acted on by centrifugal sedimentation, most crude particle is discharged through cyclone underflow opening, and most of fine grained is discharged by overflow pipe, so that
Reach separation classification purpose.
Conventional hydrocyclone structure is simple at present, and maintenance cost is low, easy to use, and disengaging time is short, but, traditional eddy flow
Device it is formal because its isolating construction it is simple, point, the time is short, overflow easily occurs and run thick underflow pressing from both sides thin situation, therefore tradition rotation
Stream device low separation efficiency.
The content of the invention
The technical problems to be solved by the invention are the problems of traditional cyclone low separation efficiency, it is therefore intended that provide reinforcing
The centrifugal cyclone device of separation, solves the problems, such as traditional cyclone low separation efficiency.
The present invention is achieved through the following technical solutions：
The centrifugal cyclone device of idetified separation, including cyclone body, the body top are communicated with the first overflow pipe, this
Body lower section is provided with the first spigot, and the side of body upper part is communicated with feed pipe, it is characterised in that first spigot
Lower section is communicated with the internal sand pump equipped with flotation agent, and the feed end of the sand pump is connected with the first spigot, the discharge end of sand pump
Cyclone separator for floatation is communicated with, the cyclone separator for floatation includes the rotary fluid that top is connected with sand pump, and the eddy flow body wall is chuck
Formula, rotary fluid inwall is porous wall, and ventilating duct is provided between the inwall and outer wall of rotary fluid, and the ventilating duct is external with eddy flow
The blower fan connection in portion.
The present invention has carried out secondary separation to the underflow that cyclone body is separated from spigot, so as to isolate underflow
In the fine grained that is mingled with, cyclone separator for floatation is exactly the separation equipment of secondary separation, and cyclone separator for floatation is with traditional cyclone in knot
Change is there occurs on structure, cyclone separator for floatation has widened ore particle being combined together with flotation the characteristics of flow of fluid in rotary fluid
The limit of particle diameter, it is to avoid the loss of subparticle, and rotary fluid accelerates flotation speed, can fast-flotation go out in underflow to press from both sides
Miscellaneous fine mineral particle, the inwall of cyclone separator for floatation is set to porous internal walls, and by porous internal walls to being filled with gas inside rotary fluid
Body, gas can promote fluid inside rotary fluid produce substantial amounts of microbubble (bubble in the presence of shearing force can macro into big
The microbubble of amount), increase the adhesive rate of subparticle and bubble；Realization principle of the invention is：By ore pulp from charging aperture
Pressurization is passed into the body interior of cyclone, and ore pulp is separated under the influence of centrifugal force, and most crude particle is through cyclone
The spigot discharge of body, and most of fine grained is discharged by the first overflow pipe, the underflow from spigot discharge can be by sand pump
Secondary pressurized is entered into cyclone separator for floatation, and underflow is in cyclone separator for floatation by secondary separation, the thin ore particle being mingled with underflow
Separate, the flowing of fluid considerably increases the collision between ore particle and bubble in flotation in cyclone separator for floatation, shortens floating
The residence time is selected, and the particle size range of the thin ore particle for flotating in cyclone separator for floatation is thinner than what traditional cyclone was separated
The particle size range of ore particle is wide, therefore, during to underflow secondary separation, can not only floatingly select in small ore particle that particle diameter is slightly larger can also to float
The fine mineral particle of grain diameter very little is selected, separative efficiency is improve.
The second overflow pipe is provided with above the rotary fluid, rotary fluid lower section is provided with the second spigot, described second
Overflow pipe is communicated to feed pipe upwards.The present invention can also be to cyclone separator for floatation secondary separation out overflow separate again,
The a small amount of rough grain being mingled with overflow is isolated, the fluid that overflow goes out from the second overflow pipe can be recycled to feed pipe, from charging
Separated again in the main body that cyclone is entered into pipe.
Filter screen is installed inside first overflow pipe.Filter screen is thick in thin ore particle from the first overflow pipe for filtering out
Particle.
The blower fan is provided with two, and two blower fans are respectively distributed to the both sides of rotary fluid.Both sides blower fan is to rotary fluid
Inside blowing, ensure that the substantial amounts of bubble in rotary fluid inside.
The sand pump is connected with the first spigot, cyclone separator for floatation by flange.Flange connection is easy to disassemble.
The present invention compared with prior art, has the following advantages and advantages：
1st, the centrifugal cyclone device of idetified separation of the present invention being used in combination by cyclone and cyclone separator for floatation, to ore pulp
Secondary separation is carried out, so as to improve the separative efficiency of ore pulp so that ore pulp grain size grading is more complete；
2nd, the centrifugal cyclone device of idetified separation of the present invention passes through filter screen and the second overflow pipe of rotary fluid and entering for main body
The multi-cycle separation that circulation canal between expects pipe realizes bleed-off fluid further increases the separative efficiency of ore pulp；
3rd, the simple structure of the centrifugal cyclone device of idetified separation of the present invention, simple structure of the present invention, simple operation.
