Definitions

  • the invention relates to a device for the hydrodynamic consolidation of nonwovens, fabrics or knitted fabrics, in which a liquid, such as water, is injected from a plurality of nozzles against the material to be solidified.
  • a liquid such as water
  • the material to be solidified passes over a rotating liquid-permeable drum, which may be additionally subjected to vacuum to suck the water.
  • the drum consists of a cylindrical massive suction tube with holes that ensure a large water drainage.
  • a structure drum is mounted, which may have finely perforated openings for solidifying the fibers, but may also impart a surface structure in the form of a pattern to the material to be processed.
  • the structure drum is always delivered according to the current state of the art with the intake manifold and replaced in the system.
  • the suction tube with its components must always be replaced with the structure of drum at the same time.
  • the conversion due to the assembly time is very time-consuming and very expensive for the customer, since he always had to buy the structural drum with the intake manifold with its components when processing new fleeces. It is an object of the invention to provide a device for hydrodynamic solidification of nonwovens, fabrics and knitted fabrics, which is inexpensive and can be replaced with little effort.
  • the device for hydrodynamic consolidation of nonwovens, fabrics or knitted fabrics comprises a suction tube with a plurality of holes on which a spaced apart structure drum is arranged, wherein the distance between the suction tube and the structure drum can be produced by exchangeable spacer elements.
  • the suction tube comprises spacer elements which can be fastened to the suction tube.
  • the suction tube can thus remain in the system and does not need to be replaced.
  • the time to change the structure drum can be significantly reduced, which increases the plant availability.
  • the spacer elements can be fastened by clamping on the suction tube.
  • the clamps are fastened to the suction tube by means of fastening elements and firmly clamp the spacer elements on the suction tube.
  • Assembly and disassembly are designed so very simple and reliable. Characterized in that the spacer elements are exchangeable fastened to the suction tube, the structure of the drum drum can be pushed over the spacer elements. The assembly or disassembly of the structure drum is done from one side, the suction tube can remain firmly in the system. The time to change the structure drum has thus shortened significantly.
  • the structure drum can be fastened to the suction tube in the region of the suction side by means of an exchangeable adapter ring.
  • this face of the structure drum could be mounted diameter-neutral on the suction tube, but the adaptation of the adapter ring increases the torque to be transmitted and the torsional rigidity of the structure drum.
  • an end face of the structure drum can be fastened to a centering device.
  • the centering can be designed so that it can be used universally for all outer diameters of structure drums. In an exchange of the structure drum so only the spacer elements are exchanged and possibly the adapter ring with the clamping elements for the front side on the suction side.
  • Figure 1 a sectional view through a drum
  • FIG. 2 an enlarged detail view through a drum
  • FIG. 3 shows a longitudinal section through part of a drum in the region of an end face
  • Figure 4 a longitudinal section through a drum.
  • a drum 1 which essentially comprises a suction tube 2 and a structure drum 3.
  • the drum 1 is part of a process plant, not shown, in which a web of non-woven or fused fibers solidified by means of high-energy radiation and optionally receives a pattern.
  • the suction pipe 2 in turn may be made of a solid cylinder equipped with a plurality of clamps 5 and spacers 6.
  • the suction tube 2 For the removal of large quantities of liquid, the suction tube 2 a plurality of holes.
  • the structure drum 3 may be formed as a thin sheet or as a fabric having a plurality of holes and optionally a surface structure.
  • the clamps 5 are formed as elongated strips which extend along the longitudinal axis of the suction tube 2. Furthermore, the terminals have 5 recesses 5a, which correspond with lugs 6a of the spacer elements 6. By means of fastening elements 7, the terminals 5 are connected to the suction tube 2 and thereby jam the spacer elements 6. The spacer elements 6 are thus perpendicular to the surface of the suction tube 2.
  • FIG. 3 by way of example, a drum 1 having an outer diameter of approximately 500 mm is shown in the upper region, whereas in the lower region, the drum 1 has an outer diameter of approximately 800 mm. It can be seen that in both embodiments, both the spacer elements 6 as well as the attachment of the end face of the structure drum 3, so adapter ring 9, cone 10 and clamping ring 11 have changed in diameter.
  • the suction tube 2 with the terminals 5 is identical.
  • the suction tube 2 is connected to a pin 12.
  • a bearing 13 is arranged with a centering 14 which receives and supports the second end face of the structure drum 3.
  • a modified structure drum 3 having a different outer diameter can be mounted by dismantling the structure drum 3 and changing the spacer elements 6.
  • the structure drum 3 is released from the clamping ring 11 with the cone 10 on the suction side S.
  • the structure drum 3 is released from the centering 14 and can thus be pushed over the spacer elements 6 of the suction tube 2.
  • the spacer elements 6 are removed from the terminals 5. Due to a new outer diameter of this embodiment 0 and the adapter ring 9 with the associated cone 10 and the clamping ring 11th dismantled and replaced.
  • the new adapter ring 9 with the cone 10 and an associated clamping ring 11 is now mounted in reverse order first.
  • new spacers 6 are mounted on the suction pipe 2, which have a changed distance to the suction pipe 2.
  • a new structure drum 3 can now be pushed, which is attached to an end face with the cone 10 and the clamping ring 11 on the adapter ring 9, and is attached to the centering 14 in the operating side.
  • the elements of the operating side B, ie bearing 13 and centering 14 are identical, since in this area the structure drum 3 are brought to the front side despite a different outer diameter to a uniform level.
  • the embodiment illustrated here with the adapted adapter ring 9 has the advantage that, with large structure drums 3, a higher torque can be transmitted and the structure drum 3 becomes more torsionally rigid.
  • connection of the end face of the structure drum 3 can be made to the adapter ring 9 diameter neutral, so that the cone 10 and the clamping ring 11 are universally applicable.
  • the spacers 6 may be formed as a round cylinder or square spacers. They may be solid, or have along their longitudinal axis a bore 6b, wherein the bore 6b corresponds to a bore in the suction tube 2, to transport the liquid from the nozzles of the solidification system to the suction pipe 2.
  • the different spacer elements 6 can be realized with a given suction pipe size 29iende total outer diameter of the drum 1 of 400 mm to 1200 mm.
