Now the dust separation of height and from combing treatment in remove.
The content of the invention
Therefore, it is an object of the invention to provide a kind of equipment, it will allow to divide dust and chopped fiber from fibrous material
From without causing to damage or cause the loss of material fiber to fibrous material.
The purpose is realized using apparatus and method of the invention.The equipment be used in the fore-spinning machine of spinning apparatus from
Fibrous material separates dust and chopped fiber, wherein the fibrous material being made up of plurality of fibers is kept by transfer unit, it is special
Levy and be, the equipment includes at least one pair of electrode, and described at least one pair of electrode is connected to high-voltage power supply, have for producing
The electric field of field intensity, wherein described at least one pair of electrode configuration is to be pointed to towards the fibrous material, and makes the fibrous material
Relative to described at least one pair of electrode movement, wherein the electric field has has same orientation on the surface with the fibrous material
Plane in stretch field wire.Methods described is used to separate dust and short fibre from fibrous material in the fore-spinning machine of spinning apparatus
Dimension, wherein transfer unit transmit the fibrous material along conveying direction, it is characterised in that the fibrous material moves across company
At least one pair of electrode of high-voltage power supply is connected to, wherein a pair at least one pair of electrode described in being pointed to towards the fibrous material
Electric field, the electric field are produced between electrode has what is stretched in the surface with the fibrous material has the plane of same orientation
Field wire.
The purpose is by a kind of method for separating dust and chopped fiber from fibrous material in the fore-spinning machine of spinning apparatus
To realize, wherein fibrous material is transmitted by transfer unit along conveying direction.Fibrous material is moved across and is connected to high-voltage power supply
At least one pair of electrode, wherein produce electric field between the electrode of a pair of electrodes pointed to towards fibrous material, and electric field field
Line with the plane of the surface identical direction of fibrous material in extend.
The purpose from fibrous material in the fore-spinning machine of spinning apparatus also by a kind of for separating setting for dust and chopped fiber
It is standby to realize, wherein the fibrous material being made up of plurality of fibers is kept by transfer unit.The equipment includes at least one pair of electrode,
And the pair of electrode be connected to high-voltage power supply for produce with field intensity（E）Electric field, and wherein the pair of electrode matches somebody with somebody
It is set to towards fibrous material and points to, and makes fibrous material relative to the pair of electrode movement.
The different power that electrical engineering science is taught in electric field can be acted on so-called dielectric.Dielectric is substantially
It is non-conductive.Dust in fibrous material is acted with chopped fiber as the dielectric in electric field.Especially when cleaning is fine
During dimension material, those power for being acted on the field lines orthogonal of electric field on the dielectric are of concern.Electric field can for example two
Produced between individual capacitor plate.Electrical engineering science and then it is taught that dielectric is moved between capacitor plate and phase
Drawn in for field lines orthogonal in showing up.Tensile stress on the dielectric is vertically acted on relative to electric field line（It is dielectric every
The power of the area of section, the field wire being pulled into dielectric in electric field is parallel）It is square proportional to field intensity.Field intensity is higher, Zhang Ying
Power is bigger, and wherein field intensity corresponds to the business of the spacing between voltage and capacitor plate.By increasing voltage and/or reducing electric capacity
Spacing between device pole plate, can strengthen field intensity, and the thus tensile stress on enhancing dielectric.
The present invention is using these rules such as set up by electrical engineering field.It is right that the fibrous material that must be cleaned is moved across
The electric field answered, wherein attracting the single composition of fibrous material with certain tensile stress by electric field.Electric field is produced towards undulation degree
Between two electrodes that material is pointed to.Electrode therein has identical function with the capacitor plate in above-mentioned example.Electrode connects
High-voltage power supply is connected to realize field intensity as big as possible in field between the electrodes.The fibrous material that must be cleaned is by appropriate defeated
Send part and move across electrode.The so-called fiber that transfer unit is configured to fibrous material is kept by transfer unit.This for example leads to
The appropriate pin cloth of offer correspondence or other kinds of attachment members are crossed to realize.The arrangement of electrode realizes in this way,
The field wire of the electric field through producing between two electrodes with the plane of the surface same orientation of fibrous material in stretch.It is preferable
Ground, field wire extends in the plane parallel with the surface of fibrous material；So, the power of maximum possible will act at fibrous material
On single composition.However, the process of orientation is enough to realize intended effect.Wherein same orientation is understood to mean that, field wire institute position
In plane relative to fibrous material surface incline be no more than 60 °.If it is 60 ° to incline, then act on fibrous material
Orthogonal active force on surface declines 50%.Experiment can be realized good clear it has been shown that with the 50% of maximum possible active force
Clean effect.It means that the surface of electrode relative to fibrous material to be cleaned surface normal towards fibrous material point to,
Even if when they are in+60 ° to -60 ° of angle.On the other hand, orientation of the electric field relative to the conveying direction of fibrous material
It is not required, because the certainty active force of electric field is orthogonally produced with field wire.
In order to more fully understand, below will using indicate field intensity vector come describe for realize two adjacent electrodes it
Between produce electric field desired effects electrode possible layout.Fibrous material is conveyed through by electrode with certain speed.Thus,
Velocity can be defined in the position on the surface of fibrous material.The velocity must apply to each position of fibrous material
Put.If for example using cylinder conveying fiber material, this will produce in result and tangentially applies on the envelope of cylinder
Velocity.Field intensity vector is pointed in each position of electric field along the direction of field wire.Left at the point of electrode in field wire, correspondence
Surface normal of the field intensity vector relative to electrode arrange.When the surface of adjacent electrode it is not parallel with respect to each other. configure when,
The composite result of the field intensity vector of each point place application that the field intensity vector of field wire comes on the comfortable field wire.The most end
Strong vector is located to be had in the plane of same orientation with the plane produced by velocity.Same orientation must be understood as expression,
Two planes deviate no more than 60 ° from parallel arrangement.Electrode is arranged as, and field intensity vector is configured to and the speed comprising fibrous material
The plane for spending vector has same orientation.
Different from from the method for cleaning fibre material known in the art, current dust granule and chopped fiber occur
Deflection, and fibrous material is not realized and electrode contact.According to known cleaning treatment, fibrous material is patted, combing and brush.
However, when fibrous material experiences cleaning treatment, all these methods all produce very big stress on fibrous material.With the party
Method is different, and the method for being proposed is substantially contactless, so that when cleaning, the method is protected by transfer unit as much as possible
The fiber of transmission is protected from fibre damage.And, in the cleaning of fibrous material and actual combing and/or parallelization and defeated
Send the separation for producing between step and clearly processing correlation.In order to the cleaning effect for realizing height no longer needs coiled fiber material
Any fiber.
In order to produce electric field, paired electrode is connected to high-voltage power supply.High voltage given by corresponding controller and
Paired electrode is fed to by electrical connector.Can use high pressure generator or and capacitor as high-voltage power supply.But must
It should be noted that connecting structure between high-voltage power supply and paired electrode is operator relative to voltage shield.Also, high-voltage power supply must be right
It is connected to energy source with answering.If using high pressure generator as high-voltage power supply, then treat to maintain electricity between the electrodes for period
The time cycle of field must assure that continuous energy supply.On the other hand, the use of capacitor has the following advantages that capacitor can lead to
Cross and be connected to energy source and charge, the high voltage that hereafter capacitor is needed in the supply of a certain amount of time producing electric field, and
Without any need that must maintain the connection.Electric field can be produced individually using the energy stored in capacitor.
Advantageously, electrode structure is plate.Two plates in a pair of electrodes are configured with certain spacing relative to each other.Therefore
The active force with field lines orthogonal can be strengthened because when the spacing relative to fibrous material broadens, the electrode of a pair of electrodes it
Between electric field field intensity increase.For example by selecting the geometry of electrode, it is possible to achieve field intensity with relative to fibrous material
The increase together of spacing.When electrode has along the thickness reduced towards the direction of fibrous material, so along the road of electrode
Line produces uneven field intensity.Other selections provide and electrode are arranged with respect to one another in obliquity.The electricity of a pair of electrodes
Pole configures in obliquity relative to each other, and the spacing wherein between electrode increases along towards the direction of fibrous material.And,
It will also be appreciated that mixed form；For example, the Part I of electrode Part II be able to can have continuously with taper profile
Section.Additionally, the end of the electrode pointed to towards fibrous material can also bend relative to the further extension of electrode.Target is not
Uniformity is further moved impurity and chopped fiber in electric field, in moving the free space with maximum field strength to.
The field wire of electric field perpendicularly enters into and/or exits electrode with the surface of electrode respectively.Adjust the geometric form of electrode
Shape, so produces slight curving field wire in various embodiments.But on effect, this is incoherent.Using electrode
It is arranged symmetrically, by the entry angle for the deterministic active force of cleaning action along field wire and the angular bisector side for exiting angle
To orientation.Plane is determined by building-up process.Always perpendicular to active force, it is between two electrodes to the plane that field wire is extended
Relative to the summation of all orthogonal active force of field wire.
Absolute field strength must be produced using the high voltage below the breakdown voltage in air.In normal atmospheric conditions it,
Breakdown voltage in air is the order of magnitude of 3200 V/mm.On the one hand based on the spacing between electrode, and on the other hand it is based on
Spacing between electrode and fibrous material determines that maximum voltage of the paired electrode without producing spark discharge can be applied to.
Experience have shown that, can reliably avoid spark discharge using the voltage of 3000 below V/mm.
The dust granule and chopped fiber not kept by transfer unit are moved to by the orthogonal active force of the field wire relative to electric field
Between electrode and keep between them.Particle and chopped fiber polarize to keep by the particle in electric field, and this causes them
Rest on in two electrodes, and become to be interleaved with each other wherein due to corresponding rubbing action.Additionally, when away from
The distance of fibrous material more far field is helpful to when strong bigger, because as field intensity increases, the active force orthogonal with field wire
Increase.Dust granule is changed into polarized dipole by polarization.These dipoles are arranged with its longer axis along the field wire of electric field.
The fact that due to being weak inductive as the dust granule of dipole, so they are interconnected with chain like manner producing series connection
The virtual capacitor circuit of arrangement.Minimum spacing between dust granule or part thereof surface can produce local elevated field
By force.Due to the field intensity that these locally increase so that dust granule keeps mutual attachment in the chain for therefore being formed is interconnected.
Conversely, be maintained at the fiber of material on transfer unit by appropriate equipment, so as to undergo the attraction of electric field.
Advantageously, electrode is spaced the mm of 0.1 mm to 5.0 with fibrous material.Preferably, model of the spacing in the mm of 0.3 mm to 2
In enclosing.Selected spacing wherein depends on the characteristic of desired cleaning effect and the fibrous material that must be cleaned.Assuming that electrode it
Between spacing at least correspond to the twice of the spacing between electrode and fibrous material, then result must apply 500 V to 15000
The high-voltage value of V.
Advantageously, make in for the equipment for separating dust and chopped fiber from fibrous material in the fore-spinning machine of spinning apparatus
Use multipair electrode.Wherein paired electrode be configured to it is front and rear each other be adjacent to biasing, so as to fibrous material all parts transmit warp
Cross at least one pair of electrode.Wherein it has to be noticed that if possible, the overall width of transfer unit is by the conveying side relative to fibrous material
Covered to horizontal paired electrode.
Advantageously, transfer unit is to include the cylinder as the pin cloth of the holding member for fibrous material.Fibrous material
Fiber kept by the pin cloth of cylinder, and impurity and chopped fiber are pulled in electric field.The rotation of cylinder makes the fiber that must be cleaned
Material movement passes through the electric field being radially disposed on cylinder.As transfer unit it is also contemplated that other facilities, for example,
Such as conveyer belt or spiked lattice.
Collected in the electric field by by impurity and chopped fiber so that the material occupies the space between electrode.In order to be able to
Space between enough holding electrode is idle, can provide cleaning equipment, and it is used for keeping between the electrode of a pair of electrodes
Space is unimpeded.The embodiment of this cleaning equipment is from known in the art.For example, by applying to aspirate, can be by the sky
Between continuous or periodic emptying impurity and chopped fiber.Or, standby ground, it is also possible to make paired electrode move to it from operating position
Maintenance position.This can be by realizing paired electrode extension or pivot.Accordingly, paired electrode is arranged on appropriate carrying
On part.
