Description
Technical field:
The invention belongs to machinery fields, are related to a kind of magnetic suspension hydraulic centrifugal device, institute in especially a kind of separation liquid
The magnetic suspension hydraulic centrifugal device of the different densities substance contained.
Background technique:
Chinese patent CN201320893256.0 discloses a kind of magnetic suspension hydraulic centrifugal tank for the full recycling of seawater,
The residual pressure of pumping hole water outlet is as direct driving force, under the premise of not increasing power consumption, by the potential energy that will pour into seawater
It is converted into the kinetic energy of tank body rotation, drives magnetic suspension hydraulic centrifugal tank around center axis rotation, to keep specific gravity in seawater different
Substance separation, including go to sea by magnetic suspension hydraulic centrifugal tank separation heavy water and fresh water, by the separation of magnetic suspension hydraulic centrifugal tank
Uranium and other materials in water, the various density that magnetic suspension hydraulic centrifugal tank of the invention is applied not only in separation seawater are different
Substance, and different densities substance contained in other liquid can be separated, magnetic suspension hydraulic centrifugal tank partition method and tradition
Chemical technology compared to belonging to pure physical method, economical and efficient, advantage is self-evident.
1, centrifugation technique principle and application
Centrifugation technique be using centrifugal force so that different material to be separated is needed to obtain accelerating separation, with separate liquid with
The Physical Separation Technology of each component in the mixture of solid particle or liquid and liquid.Centrifugation technique is mainly used for will be in suspension
Solid particle and liquid separate, or by two kinds of density differences in emulsion, and immiscible liquid separates (such as from milk
In isolate cream);It can also be used for excluding the liquid in wet solid, such as dry wet clothes with washing machine;Special hypervelocity
The admixture of gas of the also separable different densities of channel separator;It is sunk in a liquid using different densities or the solid particle of granularity
The different feature of reduction of speed degree, some sedimentation centrifugation techniques can be also classified solid particle by density or granularity.
When containing fine particle suspension stand it is motionless when, due to gravitational field effect so that suspend particle gradually under
It is heavy.Particle is heavier, sinks faster, and the small particle of density ratio liquid on the contrary will float.The speed that particle moves under gravitational field
It is related with the size of particle, form and density and again related with the viscosity of the intensity of gravitational field and liquid.As red blood cell size
Particle, a few micrometers of diameter, so that it may their infall process is observed under usual gravity.
In addition, being also accompanied by diffusion phenomena when substance settles in the medium.Diffusion is unconditional absolute.Diffusion and object
The quality of matter is inversely proportional, and the smaller diffusion of particle is more serious.And settle be it is opposite, it is conditional, could be moved by external force.
Sedimentation is directly proportional to mass of object and density, and particle is bigger, the bigger sedimentation of density is faster.To such as virus of the particle less than several microns
Or protein etc., in the solution at colloid or hemicolloid state, being just with gravity can not be it is observed that infall process for they
's.Because the smaller sedimentation of particle is slower, and diffusion phenomena are then more serious.So needing to generate powerful centrifugation using centrifugation technique
Power can just force these particles that diffusion is overcome to generate subsiding movement.
Centrifugation is exactly the powerful centrifugal force generated using centrifugation apparatus rotor high speed rotation, and particle is heavy in accelerating liquid
Reduction of speed degree separates the substance of sedimentation coefficients different in sample and buoyant density.
Since the radius of various centrifuge rotors or the distance of centrifuge tube to rotating shaft center are different, suffered centrifugal force
Difference, therefore " relative centrifugal force " or digital " digital * g " expression centrifugal force is commonly used in document.Relative centrifugal force (RCF) refers to
Under the action of centrifugal force field, centrifugal force suffered by particle is equivalent to the multiple of terrestrial gravitation, and unit is acceleration of gravity (9.8m/
s2)。
Usually particle is precipitated with relative centrifugal force (RCF).And the size of relative centrifugal force depends on locating for sample
Position to axle center horizontal distance, that is, radius of turn r and revolving speed n, its calculation formula is:
RCF=1.118 × 10-5×n2r(g)
Here, n is represented revolving speed (r/min), r, represents radius of turn (cm)
(T the time required to particle separation, precipitating in mixed liquors) calculation formula are as follows:
Ts=27.4 (logRmax-logRmin)L/n2r2(Dp-Dq)
Here,
Rmax, it is centrifuged the horizontal distance (cm) in bottom to the axle center of test solution
Rmin, it is centrifuged the horizontal distance (cm) in face to the axle center of test solution
R, particle radii (cm)
Dp, particle density (g/cm3)
Dq, mixed liquor density (g/cm3)
L, viscosity of mixed liquid (po)
Two above formula just can determine that the centrifugal force and centrifugation time of various differential centrifugations.
Conventional centrifugal technology is widely used in the portions such as chemical industry, petroleum, food, pharmacy, ore dressing, coal, water process and ship
Door.It is broadly divided into perforated wall centrifuge and sedimentation-type centrifuge two major classes.
The cardinal principle of perforated wall centrifuge is that the centrifugal force generated by the centrifugal reel to run at high speed (cooperates appropriate
Filter material), the liquid phase acceleration in solid-liquid mixed liquor is thrown away into rotary drum, and solid phase is stayed in rotary drum, reach separation solid and liquid
Effect, or be commonly called as dehydration effect.
The cardinal principle of sedimentation-type centrifuge is the powerful centrifugal force generated by rotor high speed rotation, accelerates mixed liquor
The sinking speed of middle different specific weight ingredient (solid phase or liquid phase) separates the substance of sedimentation coefficients different in sample and buoyant density
It opens.
Select centrifuge must according to the size and concentration of solid particle in suspension (or emulsion), solid and liquid (or
Two kinds of liquid) density contrast, liquid viscosity, filter residue (or sediment) characteristic carry out lectotype selection.
2, the principle and application of magnetic levitation technology
Electromagnetic suspension technology principle is not abstruse, it is the property with magnet " identical charges repel each other, and there is a natural attraction between the sexes ", has magnet
Gravitational ability is resisted, i.e. " magnetic suspension ".
Since magnet has that identical charges repel each other and there is a natural attraction between the sexes two kinds of forms, therefore also there are two types of corresponding for the application of magnetic levitation technology
Form: one is the electromagnetism operating systems designed using magnet principle of same-sex repulsion, it is formed using superconductor electromagnet
Generated mutual expelling force between the magnetic field that magnetic field and coil are formed, makes object suspend;It is another then be using magnet opposite sex phase
The system inhaling principle and designing, it utilizes the gravitational equilibrium of attraction and object, so that object be made to suspend.
(1) maglev type
It according to the substance to suspend is realized, can be generally divided into: often leading suspension, superconductive suspension and permanent magnet and suspend three kinds.Institute
Meaning is often led, superconduction and permanent magnet suspend, and refers respectively to form electromagnet, superconduction material that suspending power needs to manufacture using normal conductivity
Expect the electromagnet of manufacture and the magnetic field that permanent magnet generates.Table 1-1 indicates the stress relationship and suspended pattern between two objects.
Table 1-1 magnetic suspension is classified according to the relationship between the object of interaction
(2) application of magnetic levitation technology
1) according to magnetic suspension principle, common following four form in practical application:
1. being suspended using permanent magnet
Permanent magnet is that possessed very strong magnetic after effect manufactures after being magnetized using hard magnetic material.Due to no matter using
Repulsion or attraction mode realize suspension, and permanent magnet is all not consume the energy in use, therefore high in power conservation requirement
Occasion has special advantage.The disadvantage is that the magnetic field that permanent magnet generates is difficult to control, it is therefore desirable to and the combination of normal conducting magnetic iron makes
With.And strong permanent magnet cost of manufacture is high, and common material is difficult to generate enough magnetic induction intensity again, therefore work is limited
System.
2. being suspended using superconducting electromagnet
Superconductive suspension is to be passed through heavy current in hollow superconducting coil, is suspended to generate high-intensity magnetic field and realize.Superconductive suspension
Attractive suspension and repulsion two kinds of forms of suspension.It is floated using attraction, since electric current is difficult to control, so Chang Yuchang is led
Mode is used in combination.It is that superconductor and another conductor is allowed to generate relative motion, using in another conductor when being suspended using repulsion
The induced current of middle generation obtains repulsion.Superconducting electromagnet suspension is usually used in magnetic suspension train.Superconducting electromagnet suspends excellent
It is self-stabilization that point, which is system, is not necessarily to active control, and without heavy iron core, coil energy loss is few.But superconductive suspension
System needs complicated liquid nitrogen cooling system.
3. the current vortex using high-frequency induction suspends
The high-frequency alternating magnetic field that radio-frequency induction coil generates can induce current vortex in metal again, and such vortex is also same
Sample can generate magnetic field, and must be with original magnetic direction on the contrary, realizing that repulsion suspends in being available with this principle.It is this
The advantages of method is static suspension can to may be implemented to any electric conductor, and not requiring suspended substance is magnetizer.This method is
Through being applied to the melting of high-purity, refractory metal, since the suspending power of induction suspending method is decided by faradic size,
And normal conductor coil is generally used, energy consumption is larger, and application surface is relatively narrow.
4. being suspended with the normal conducting magnetic iron of controllable direct current
Routine conductive maglev is to utilize to be passed through magnetic field caused by the normal conductor coil of DC current, the suction generated to ferromagnetic material
Gravitation suspends to realize.Since this suspended pattern is substantially unstable, it is therefore desirable to carry out closed loop control to suspension air gap
System, the electric current of regulating winding control the size of attraction, to realize the stable suspersion for being suspended object.To improve magnetic induction
Coil is usually wound on the iron core of ferromagnetic material by intensity.This mode requires to introduce active control system to remain stable outstanding
Floating, being suspended object must be magnetizer.
2) application field of magnetic levitation technology and its extensively, mainly it is following some industry and civil field applications: 1. magnetic
2. 3. 4. magnetic suspension antihunting device 5. magnetic suspension carrying is smelted in magnetic suspension to magnetic suspension bearing to aerotrain
(3) magnetic levitation technology feature
Magnetic levitation technology mainly has advantage following prominent:
1) contactless.It is not contacted since discord is suspended body, it is no to rub, without mechanical wear, low energy consumption, low noise
Take with low-maintenance.
2) due to not needing Supporting Media, so can be answered under vacuum, the various specific conditions such as ultra-clean and high temperature, low temperature
With, and can be with long-term work without lubrication and maintenance.
3) active control may be implemented, so can obtain in the various systems for needing vibration damping, support hardness that can change
To application, it is also easy to realize computer control, and then realize movement, monitoring and automatic detection and diagnosis, high degree of automation.
4) distribution of force is uniform, therefore magnetic suspension support force is generally evenly distributed on entire magnetic pole strength, is significantly reduced and is answered
Power can reduce system manufacturing cost, improve reliability of service life.
(4) presently, there are the technical issues of:
Although magnetic levitation technology has above-mentioned many advantages, but still comes with some shortcomings:
1) since magnetic suspension system is to complete suspension, guiding and driving function, maglev peace after power-off with electromagnetic force
The problem of brake problem after the power failure of full safeguard, especially magnetic suspension train is still to be solved, while its high speed is stablized
Property and reliability also need the Operation trial of some time.
2) hoverheight of routine conductive maglev technology is lower.Therefore flatness of the magnetic suspension train to route, subgrade settlement
Requirement in terms of amount and switch structure is higher compared with superconductor technology.
3) super-conductive magnetic suspension technology due to the more normal waveguide technology of eddy current effect suspension energy consumption it is bigger, cooling system weight, cost
Also relatively high, whole system is also complicated, and high-intensity magnetic field all has an impact to human body and environment.
3, the principle and application of magnetic suspension wipping top
Magnetic suspension wipping top is that the magnetic gyroscope of a rotation is suspended in aerial keep surely under the interaction of big toroidal magnetic field
Surely the device rotated.It is to be referred to as the magnetic field low-potential energy area of " potential well " using one existing for big toroidal magnetic field top, in magnetic
Gyroscopic inertia rotates and is in a kind of phenomenon of floating state when field repulsive force and gyro gravity reach balance.Due to the rotation of gyro
Turn the effect only by windage resistance, it is possible to which the long period keeps inertial rotation without stopping, if be in
Rotation status theoretically can be even kept in vacuum forever.It is widely used in earth magnetism inertial navigation, magnetic confinement neutron experiments etc.
Field.
4, magnetic bearing
Magnetic suspension bearing is a complicated Mechanical & Electrical Combination System.In the research process of early stage, it by mechanical system and
Control system two subsystems composition.The development of computer technology will be counted to realize that the intelligence of whole system provides condition
Calculation machine, which is added in system, obtains magnetic levitation bearing system.In this system, it can more easily be picked up from the external world using computer
The number of winning the confidence, and Intelligent treatment is carried out to it, realize the stable operation and control of bearing.
Mechanical system is made of rotor and stator, and usually they are made of ferromagnetic laminates.Rotor pack is mounted in axis
On diameter, it is provided with slot on stator lasmination, and is wrapped coil to provide magnetic force.
Control system refers to the electrical system of control rotor-position, and simple control system is by sensor, controller and power
Amplifier composition.Sensor: i.e. detecting element, is the important component of magnetic suspension bearing, and position sensor turns for detecting
The drift condition of son, velocity sensor are used to detect the movement velocity of rotor;Controller: being the core of entire magnetic suspension bearing
The heart, performance determine the quality of magnetic suspension bearing, and effect is that the position error signal detected to sensor carries out appropriateness
Operation so that rotor has high-precision positioning, can be made by rapid appropriate curent change under the interference effect of external force
Rotor returns to base position;Power amplifier: it is electric current needed for providing generation electromagnetic force to electromagnet that it, which is acted on,.
The basic principle of magnetic suspension bearing work: the axis deviation signal of rotor is detected by position sensor, by the signal
Be sent into controller, by the electric current in power amplifier control electromagnet, thus the variation for generating electromagnetic force make rotor suspension in
Defined position.
Magnetic suspension bearing can have many types by a variety of methods such as magnetic suspension mode and structure to classify.By suspended pattern
Active and passive type can be divided into;Vertical, horizontal, inner-rotor type and outer-rotor type can be divided by structure;It can be divided by active force
Aspiration-type and repulsion formula;Entirely contactless type and part contact-type can be divided by the way of contact;It can be divided by solenoid type super
Conduction, exchange control formula and DC control formula.At present, in magnetic suspension bearing research field mainly with the DC control formula magnetic of active
Suspension bearing is research object.
It is noted that passive magnetic suspension bearing has system design simple compared with Active Magnetic Suspending Bearing, and
It can stablize in the case where no controlling unit but it cannot generate damping, that is, lack picture mechanical damping or as active bearings
Such additional means, therefore the stable region of this system is very little, the small variation of external interference can also make it tend to be unstable
It is fixed.
What civil field was relatively more universal at present is applied to refrigeration system magnetic suspension centrifugation technique, mainly for refrigeration system ton
For centrifugation technique used in compressor, centrifugal compressor uses magnetic bearing, by the effect of magnetic force, axis and axis when operating
Contactless rotation is held, therefore reduces the energy loss of gear drive generation, revolving speed is higher.Will not friction bearings, save more
Complicated lubricating oil return system.Noise is significantly reduced.In addition, the application of magnetic suspension blower is also in the development phase.
Two, the shortcoming of existing centrifugation technique
1, traditional mechanical centrifugal technology relies on motor and provides kinetic energy, and energy consumption is higher;
2, current magnetic suspension centrifugation technique is mainly used for refrigeration compressor art, and essential core technology is magnetic suspension shaft
The utilization held, and be substantially blank in widely used centrifuge separation field, it is big sorry to can't but be one;
3, existing magnetic suspension bearing mainly be electromagnetic energy, energy consumption is larger, and control system is complex.
