Definitions

  • the invention concerns a plastic end disk according to the preamble of claim 1 . Moreover, the invention concerns a manufacturing method for a filter element by employing such an end disk according to the preamble of claim 8 .
  • plastic end disks have the task to provide a usually circular ring-shaped surface into which a filter medium can be embedded in a seal-tight way. Moreover, the plastic end disk should have a connecting contour that is suitable for producing a seal-tight and detachable connection to a connecting element.
  • Such an end disk is disclosed in, for example, DE 199 19 289.
  • the manufacture of a plastic end disk is disclosed that is used for a seal-tight connection to a filter medium.
  • stacked plastic disks are employed that have different thermal properties so that they can be selectively heated by inductive treatment.
  • DE 101 06 734 discloses a method for producing a connection between a fluid-impermeable plastic material and a fluid-permeable filter material.
  • the plastic end disk is plastified in the area to be connected by an infrared heat source wherein the infrared heat source must have certain predetermined technical features.
  • a disadvantage of the first plastic end disk is that it must contain metal particles in order to be heatable by the inductive heat source because such plastic end disks are difficult to dispose of.
  • the plastic end disk of the second method must not contain pigments for a colored or black design of the material which pigments have great heat-absorbing properties. This can cause in case of quick and intensive heating exothermal reactions within the synthetic material resulting in destruction of the material. Even without the heat-absorbing materials within the plastic material the radiation intensity that is acting on the plastic material must not be too great because this can cause bubble formation and burns on the surface of the plastic material.
  • the inventive plastic end disk comprises two substantially circular cylindrical plastic layers wherein an end face plastic layer of the plastic end disk can be connected to a hollow-cylindrical zigzag-shaped folded filter medium by means of a melting process of the plastic layer at the end face.
  • the plastic layers can be glued or welded to one another, produced in a two-component method or can be simply stacked.
  • the plastic layer at the end face is plastified and in the plastified state is pressed onto the tips of the fold ends of the filter medium and hardened thereat.
  • the plastic end disk can be used preferably as a liquid filter but it is also possible to use it as a gas filter.
  • the plastic layer at the end face is designed to be substantially transparently for infrared radiation or heat radiation and the plastic layer directly adjacent thereto is designed to be substantially absorbent for infrared radiation.
  • the end face plastic layer When irradiating with an infrared source, the end face plastic layer is penetrated by the infrared radiation and is heated by excitation of the atoms and molecules. The major portion of the infrared radiation will however penetrate the end face plastic layer and will impinge on the boundary layer to the neighboring plastic layer where it is partially absorbed and partially reflected. The reflected infrared radiation in turn will heat the end face plastic layer from the interior. The infrared radiation proportion that impinges on the interface between the plastic layers heats the boundary layer in the area of the neighboring plastic layer.
  • the end face plastic layer is preferably of a natural color or is colored with a light-transparent or laser-transparent pigment.
  • the cycle time can be significantly reduced because the material that is substantially transparent for infra red radiation at great radiation input does have the tendency to form bubbles and the radiation proportion will be better distributed in the plastic end disk. In this way, from the beginning a greater radiation intensity can be employed in the process which leads to a reduction of the processing time.
  • the main heating zone is within the area of the boundary layer so that the remainder of the neighboring plastic layer remains shape-staple thus improving handling.
  • the plastic end disk is produced by a two-component injection molding process from a thermoplastic synthetic material.
  • the plastic layer that absorbs infrared radiation is injection molded and, subsequently, the end face plastic layer that is substantially transparent for infrared radiation is injection molded onto the absorbing layer.
  • the end face plastic layer is comprised of a substantially glass fiber-free polyamide and the neighboring plastic layer having absorbing properties is comprised of a glass fiber-reinforced polyamide to which dark heat-absorbing particles are added.
  • the advantage results that the plastification process can be performed very uniformly and the attachment to the zigzag-shaped folded ends of the filter medium is particularly intimate. The required stability of the plastic end disk is then ensured by the embodiment of the neighboring plastic layer from glass fiber-reinforced polyamide.
  • the end face plastic layer has at a radial end an axially projecting annular collar.
  • the latter can be arranged at the outer radial end or the inner radial end of the end face plastic layer.
  • the annular collar extends axially away from the filter medium and forms a sealing contour that matches a corresponding sealing counterpart.
  • This sealing counterpart can be a central tube of the housing or of the filter element or can also be a contact socket of the housing.
  • the sealing contour is formed as an integral part of the annular collar.
  • the plastic layer neighboring the end face plastic layer furthermore forms a functional element, in particular a liquid outlet.
  • the plastic layer neighboring the end face plastic layer is the side of the plastic end disk facing away from the filter medium wherein it is possible in this way that this plastic layer also serves for centering and fixation of the filter element in a housing or forms a through opening and a thread for a discharge screw.
  • the side of the neighboring plastic layer that faces the end face plastic layer has a surface area-enlarging relief contour.
  • This can be, for example, in the form of an audio record contour or in the form of a circumferentially extending wave line or sawtooth line. Since the two plastic layers are produced by a two-component method, the end face plastic layer has therefore a matching surface profile.
  • the first plastic layer that is essentially transparent for infrared radiation is trans-irradiated by the infrared radiation source.
  • the infrared radiation source can be a laser or an infrared radiator.
  • the infrared radiation penetrates the first end face plastic layer that is substantially transparent and thus impinge on the second plastic layer that is substantially absorbent for infrared radiation.
  • a great heat above the melting temperature develops by absorption of infrared radiation so that the boundary layer begins to plastify.
  • said plastic layer is plastified from the interior to the exterior uniformly and homogeneously.
  • the infrared radiation source is removed and the adjacently positioned terminal edges of his zigzag-shaped folded fluid-permeable filter material are pressed into the still melted plastified area of the first plastic layer. This position is maintained until a fixed connection of the terminal edges of the filter material with the synthetic material in the pressed-in state is achieved.
  • FIG. 1 a liquid filter in section view
  • FIG. 2 a detail view of the plastic end disk in a detail illustration.
  • the FIG. 1 shows a liquid 10 , in particular fuel filter, with a cup-shaped housing 11 provided with an intake 12 and an outlet 13 .
  • the outlet 13 is arranged centrally on the end face of the cup-shaped housing 11 and the intake 12 is arranged concentrically about the outlet 13 distributed onto several openings.
  • a filter element 14 is arranged that separates seal-tightly an unfiltered side 30 from a filtered side 31 .
  • the filter element 14 is secured axially in the housing 11 by a bottom member 15 .
  • the bottom member 15 has a support for the filter element 14 as well as an inner thread 16 that provides at the bottom of the cup-shaped housing a receptacle for a drainage screw 17 .
  • the liquid filter 10 As a fuel filter, especially a diesel fuel filter, in the lower area of the cup-shaped housing 11 water that is heavier than fuel will collect that is then drained by means of the drainage screw 17 from the cup-shaped housing 11 .
  • the cup-shaped housing 11 is closed off by a metallic cover plate 18 .
  • This cover plate 18 has a centrally arranged threaded receptacle 19 that receives a threaded socket of a counterpart, not illustrated, for example, a fuel assembly or a cylinder block.
  • the cover plate 18 is secured to the housing wall of the cup-shaped housing 11 by a securing plate 20 wherein the securing plate 20 on the one hand is connected to the cup-shaped housing 11 by crimping in a seal-tight and non-detachable way and on the other hand secures the cover plate 18 by a fold also in a seal-tight way.
  • the intake and outlet openings 12 , 13 of the liquid filter are arranged also.
  • the securing plate 20 has axially outwardly a circumferential groove for receiving a seal 21 that serves for sealing the liquid filter 10 relative to the counterpart.
  • the filter element has a hollow-cylindrically arranged preferably zigzag-shaped folded filter medium 20 made of filter paper or a non-woven filter material or a synthetic material or a mixture of all of the above and is supported by an inwardly positioned support tube 23 against collapse.
  • the filter element 14 is closed at the bottom by a closed lower end disk 24 that is made of a thermoplastic material that is substantially transparent for infrared radiation.
  • the end disk 24 is welded by an infrared welding method to the bottom member 15 that is substantially absorbent for infrared radiation. It is however also conceivable to provide a nitrile rubber end disk that rests on the bottom member 15 or is connected to it by an adhesive.
  • the filter element 14 On the opposite end face the filter element 14 has an open end disk 25 which has an end disk part 26 and a sealing part 27 .
  • the sealing part 27 is in the form of an annular collar 33 that axially extends away from the filter medium. It ends in a T-shaped member wherein one end of the T member provides a radial seal 28 relative to a vertical extending circumferential edge of the cover plate 18 and the opposite end of the T member of the sealing part 27 rests axially against a horizontal contact surface of the cover plate 18 .
  • FIG. 2 shows a detail in the area of the plastic end disk. Components that correspond to those of the preceding figure are identified with same reference numerals.
  • the two-layer configuration of the plastic end disk 25 can be seen clearly.
  • the end face facing the filter medium 22 has a plastic layer 32 that is transparent for infrared radiation which completely receives the filter medium 22 .
  • the transparent plastic layer 32 has in the radial inner area an annular collar 33 a that continues as a sealing part 27 .
  • An absorbent plastic layer 34 is connected to the transparent plastic layer 32 and has at its radial inner end also an annular collar 33 b that is shaped so as to match the shape of the annular collar 33 a and supports it in a shape-stabilizing way.
  • a sawtooth contour 35 On the interface between the transparent plastic layer 32 and the absorbent plastic layer 34 there is a sawtooth contour 35 . It serves for providing better absorption and reflection of the infrared radiation passing through the transparent plastic layer 32 so that the plastification process in the area of the interface happens faster.
