Definitions

  • the invention relates to a device for separating dirt and short fibers on a carding machine and to the method and a lid for use in the device.
  • the revolving lids basically fulfill four functions, they are intended to dissolve the fiber flakes down to the individual fibers, to separate out sturgeon particles, to dissolve the fibers and to parallelize and orient the fibers. Since, as described above, an excretion of dirt particles takes place only after the absorption of individual fibers, it is also necessary to reduce the intake of individual fibers if the raw material has little contamination. The inclusion of individual fibers in turn depends on the position of the trimmings to each other and from the clothing design. In addition, the longitudinal orientation of the fibers is significantly influenced by the distance between the trimmings, the so-called carding nip.
  • This prior art carding technique has the disadvantage that simultaneous cleaning and longitudinal alignment of the fibers is a compromise for the requirements of both processes. Improvements in the cleaning of cotton in the blow-room and an increase in performance in the entire cotton processing sector over the last few years have made the demands on the quality of carding ever greater.
  • the use of today's high-performance carding machines and the improvements in the cleaning facilities mean that today's processes in relation to the achieved dirt excretion excessive fiber damage is to be accepted.
  • a high rate of soil removal in traveling lids has the disadvantage that a deep carding must take place, that is, many good fibers are added to the clothing and removed from the carding process in order to achieve a high degree of contamination.
  • the object of the invention is to provide a device and a method which allow a separation of dirt and short fibers from a fiber without causing damage to the fiber or a loss of good fibers.
  • the object is achieved by a device for the separation of dirt and short fibers on a card with at least one lid with a flat bar with a flat top set with clothing tips and a drum with a drum set, said the flat clothing of the drum set is arranged at a distance opposite. At least a portion of the clothing tips are formed as pairs of electrodes and connected to a high voltage source, wherein in each case between two, a pair of electrodes forming, clothing peaks an electric field is constructed.
  • the object is also achieved by a method for the separation of dirt and short fibers on a card, wherein a lid with a mounted on a cover foot cover set with clothing tips a drum is opposite, which transports to be cleaned fiber by means of a drum set on the covers. At individual clothing tips an electrical voltage is applied and constructed at least in partial areas of the flat clothing each between two adjacent clothing tips an electric field whose field lines extend in a direction equal to the cover foot plane.
  • a dielectric is a substantially non-electrically conductive particle. Dirt and short fibers in a fiber material behave like a dielectric in an electric field. In particular, those forces which act on a dielectric perpendicular to the field lines of an electric field are of interest for the cleaning of fiber material. For example, an electric field can be established between two capacitor plates. A dielectric is drawn into the field between the capacitor plates according to the electro-technical teaching, perpendicular to the course of the field lines.
  • the tensile stress acting perpendicular to the electric field lines on a dielectric is proportional to the square of the field strength.
  • the tensile stress is the greater, the higher the field strength, the field strength corresponding to the quotient of the electrical voltage and the distance between the capacitor plates.
  • a fiber material to be cleaned is moved past a corresponding electric field, wherein the individual components of the fiber material are attracted by a specific tensile stress from the electric field.
  • the electric field is built up between two clothing tips of a lid, which serve as electrodes.
  • the clothing tips are to be equated with the capacitor plates from the above example.
  • the clothing tips are connected to a high voltage source to achieve the highest possible field strength in the field between the electrodes.
  • the fiber material to be cleaned is moved by the drum set at the clothing tips, while the so-called good fibers are held by the drum set.
  • the arrangement of the clothing tips has the consequence that the field lines of the constructed between two clothing tips electric field in a direction equal to the cover foot plane.
  • the field lines extend in a plane which lies parallel to the lid foot surface on which the part of the clothing tips which are used as electrodes.
  • a plane in which the field lines lie is not inclined more than 60 ° with respect to the lid foot surface on which that part of the clothing tips used as electrodes is inclined.
  • the force acting orthogonally on the surface of the fiber material decreases by 50%.
  • An alignment of the electric field with respect to the drum set and thus the fiber material can be achieved by a corresponding construction of the lid and its inclination relative to the tangential to the drum.
  • the decisive force of the electric field occurs orthogonal to the Field lines on.
  • an adjustment is made such that the field lines are inclined less than 60 ° with respect to the tangential to the drum surface.
  • a possible inclination of the clothing tips relative to the cover footer is to be considered.
  • the possible arrangement of the clothing tips to achieve the desired effect of the electric field built up between two electrode pair forming electrode tips is explained below with reference to the field strength vectors.
  • the fiber material is transported past the clothing tips at a certain speed. Due to this, instead of the surface of the fiber material, a velocity vector can be defined. This velocity vector is to be applied at each point of the fiber material. In a transport of the fiber material with the drum, this results in velocity vectors which are applied tangentially to the envelope of the drum.
  • the field strength vectors point at each point of the electric field in the direction of the field lines. At the point where the field lines leave the clothing tips, the corresponding field strength vector is orthogonal to the surface of the clothing lace.
  • the field strength vector of a field line results as a result of the field strength vectors applied at each point on this field line.
  • This resulting field strength vector lies in a plane which is the same as the plane formed by the velocity vectors. Under the same direction is to be understood that the two levels do not deviate more than 60 ° from a parallel arrangement.
  • the arrangement of the clothing tips is such that a field strength vector is directed to a plane containing the velocity vector of the fiber material, the same.
  • the clothing tips of a traveling lid is designed as electrodes.
  • the electrode pairs formed in each case by two opposing clothing tips can be arranged further away from the drum clothing than the clothing tips which are provided for carding the fiber material.
  • all clothing tips of a revolving lid can be used as electrodes for cleaning the fiber material and, for example, the subsequent traveling lid can be used for carding.
  • the electrode tips used clothing tips are connected to generate an electric field with a high voltage source.
  • the high voltage is switched by an appropriate control the electrode pairs via electrical connections.
  • the high voltage source is arranged in the flat bar. This is especially in terms of operational safety and the protection of operating personnel against electrical shocks of advantage.
  • high voltage source high voltage generators or capacitors can be used. It should be noted, however, that the connection between the high voltage source and the electrode pairs is designed to provide shielding to the operator.
  • the high voltage source is correspondingly connected to an energy source. If a high-voltage generator is used as the high-voltage source, ensure a continuous power supply for the period during which the electric field between the electrodes is to be maintained.
  • Such a power supply can be ensured for example by the use of accumulators.
  • the use of a capacitor has the advantage of having this over a connection can be charged to a voltage source and then for a certain time to generate the electric field provides the necessary high voltage without this connection must be maintained.
  • the electric field can be generated solely by the stored energy of the capacitor.
  • a transmission means for the electrical supply of the high voltage source from a voltage source is provided.
  • the revolving lid can be temporarily connected either during use as a cleaning element or in the return during a charging process with the voltage source.
  • sliding contacts or contactless induction transmissions are. Sliding contacts can be used to transmit direct current (DC) or alternating current (AC).
  • the frequency used does not matter when transmitting AC.
  • alternating current (AC) can be used.
  • the frequency used is important, since the frequency of the size of the transmission unit as well as the loss to be accepted is largely determined by the frequency.
  • the arrangement of the transmission means and the duration of the transmission are dependent on the construction and operation of the revolving lid. Construction and execution of suitable transmission means for connection of high voltage source and voltage source are well known in the prior art.
  • the clothing tips serving as electrodes are provided with a so-called side cut.
  • This has the consequence that the distance between the facing surfaces of the clothing tips of a pair of electrodes decreases with increasing distance from the drum set.
  • the force effect perpendicular to the field lines can be increased by the fact that a field strength of the electric field between the electrodes of the electrode pair increases with increasing distance from the fiber material.
  • An increasing with the distance to the drum set field strength is achieved by the geometric shape of the clothing tips with a side cut.
  • the fact that the clothing tips have a decreasing thickness in the direction of the drum set results in an inhomogeneity of the field strength with the course the clothing tips. A targeted inhomogeneity draws the impurities and short fibers further into the electric field into a free space with the greatest field strength.
  • the field lines of an electric field respectively occur perpendicular to the surface of the clothing tips serving as electrodes. This results in slightly bent field lines in various embodiments, adapted to the geometric shape of the clothing tips. However, this is not relevant to their effect.
  • the force effecting the cleaning of the fiber material is directed in the direction of the bisecting line from the entry and exit angles of the field lines.
  • the plane is determined by how the resultant of the field lines runs. The plane in which the theoretical field lines run is always perpendicular to the force effect, which results from the sum of all forces orthogonal to the field lines between two clothing tips.
  • the absolute field strength must be generated with a high voltage which is below the breakdown voltage in the air.
  • the breakdown voltage in air is under normal climatic conditions of the order of 3,200 volts per mm.
  • the maximum tension which can be applied to the serving as electrode pairs clothing tips of the revolving flat set without sparking is determined on the one hand by the distance between the clothing tips and on the other hand by the distance of these clothing tips for drum set. Experience has shown that a sparkover can be reliably avoided with a voltage of less than 3,000 per mm.
  • the not held by the drum set dirt particles and short fibers are pulled and held by the force orthogonal to the field lines of the electric field between the clothing tips.
  • the retention of the particles and short fibers is given by a polarization of the particles in the electric field, which causes them to be ajar against one of the two clothing tips and snag each other by appropriate friction.
  • it helps when the field strength increases with the distance from the drum set, since the force action orthogonal to the field lines also increases with increasing field strength.
  • the dirt particles are transformed into polarized dipoles. These dipoles are arranged with their longer axis along the field lines of the electric field. Since the dirt particles are weakly conductive as dipoles, their concatenation results in virtual capacitor circuits in series.
  • Minimal distances between the debris or parts of its surfaces can result in locally increased field strengths. Due to these locally increased field strengths, the dirt particles stick to one another in the formed chain. In contrast, the good fibers are held by the drum set and thus withstand the force of attraction of the electric field.
  • a lid for use in a device for removing dirt and short fibers on a card with a flat bar and a clothing strip attached to the flat bar, wherein the clothing strip is provided as a flexible clothing.
  • the flexible clothing consists of a foundation and U-shaped wire hooks with two tips and a spine connecting the spikes.
  • the foundation is electrically insulating, so that between the various adjacent wire hooks a reduction of electrical voltage is possible only in accordance with the electrical insulation. A voltage reduction between two adjacent wire hooks is practically prevented by the electrically insulating effect of the foundation.
  • the tips are arranged on the side facing away from the flat rod side of the clothing strip and the back on the flat bar side facing the clothing strip. Between the clothing strip and the flat rod, an insert is provided, which electrically conductively connects individual backs of the wire hooks and is provided with contact points for connection to a high-voltage source.

  • the coating can already be applied as conductor tracks. However, it is also possible to cut out the printed conductors after the introduction of the film from a full-surface coating, for example with a laser.
  • the insert can be designed as a rigid rod or incompressible flexible film.
  • the insert is preferably disposed between the foundation and the backs of the U-shaped wire hooks.

If the spring element is mounted between the foundation respectively the back of the wire hooks and the insert, then an electrically conductive spring element is provided. In this case, an elastic spring element can be used, which has the property of being continuous for electric current only in one direction.
  • the spring element would be in this case on the one hand electrically conductive in the direction of the insert to the wire hooks, on the other hand, however, electrically insulating in the transverse direction, so that no short circuit can occur.
  • the electrically insulating layer can serve, for example, at the same time as a spring element for obtaining the contact security with a suitable choice of material.
