Definitions

  • the present invention relates to a device for supporting, stacking and transporting firing material, in particular when firing ceramic products according to the preamble of claim 1.
  • the fireproof structures comprise of support assemblies, in which from several supports, and support beams, such as support beams, crossbeams, large plates or the like, corresponding brackets or support systems for the ceramic products or generally the kiln are formed.
  • the supports are connected by means of steel receptacles with the kiln car.
  • a steel receptacle has on all sides vertically superposed pairs of screws, which are aligned vertically and centrally on the usually designed as a square tube support.
  • the support is firmly clamped on all sides and can be aligned by opposing adjustment of the opposite pairs of screws.
  • this conventional system for fixing and adjusting the support of a kiln car body presents several disadvantages.
  • the support is very difficult to align in particular vertically, as to each set two pairs of screws exactly opposite and all screw pairs, so eight screws must be loosened.
  • This is z. B. particularly difficult to set several supports of a kiln car body against each other in alignment.
  • the screws can already loosen after a few furnace cycles, since these furnace cycles by heating and cooling thermal expansions in the support, cause the steel receptacle and the screws, which in turn can solve the fixation of the support.
  • These strains can also support the usually made of ceramic material, eg. B. Al 2 O 3 , RSiC, SiSiC, NSiC or mullite damage damage.
  • a device is to be provided which allows easy alignment of a support. The device should dampen shocks on the kiln car relative to the kiln car body and a relaxation of the determination of the support should also be avoided over several furnace cycles. In addition, this device should be easy to manufacture.
  • the inventive device for supporting, stacking and transporting kiln material comprises an assembly of supports and support beams, in particular support beams, cross beams, large plates or the like, and at least one sleeve in which a support is arranged.
  • the sleeve and support are substantially square, but may also have other cross sections, we have round or polygonal.
  • the sleeve has at least one adjusting means, which in the Sleeve mounted and can be pressed against the support and on the other hand further comprises at least one, formed from at least one elastically acting element pressure medium, which is biased by the action of the adjusting means and so restoring forces builds up against the support.
  • the sleeve is preferably arranged on a kiln car, so that the particular ceramic kiln, which is set on the support assembly, as simple and even automated in the kiln and out of it can be transported.
  • adjusting means and pressure means By the opposite arrangement of adjusting means and pressure means a very simple alignment of the support in the sleeve is possible.
  • the support can not be loosened by thermal expansion during the furnace cycles due to the resilient mounting of the pressure medium, since the pressure means compensate for such thermal expansion and press the support flexible at any time to the adjusting means.
  • the pressure medium is designed as a screw or plate spring, which allows a biasing force of 500 to 2000 N. But it is, for example, an elastic plastic sleeve, leaf spring or the like. Usable.
  • pressure plates preferably made of steel, to avoid punctiform pressure voltage peaks between the adjusting means or the pressure means and the support.
  • these printing plates can be thermally decoupled from the support by an additional layer of a thermally insulating material.
  • a thermally insulating material comprises a ceramic hard fiber or a mica laminate.
  • the bottom of the sleeve is substantially closed and an adjustment means is arranged in the bottom of the sleeve.
  • This adjustment means a defined height alignment of the sleeve can be completed.
  • the bottom of the sleeve is functionally connected to the sleeve, ie that it does not necessarily have to be mechanically connected directly to the sleeve. Rather, the sleeve on the floor z. B. a kiln car, so that then the bottom of the kiln car functionally forms the bottom of the sleeve and therein the height adjustment means is arranged.
  • two first adjustment means are arranged on one side of the sleeve substantially centrally and vertically one above the other.
  • the vertical distance of the adjusting means is 20 to 100 mm in commonly used supports, so that in the plane parallel to the first adjustment means a one-sided vertical alignment of the support is made possible.
  • two second adjustment means can then be arranged substantially centrally and vertically one above the other on a side of the sleeve adjacent to the first adjustment means, so that a mutually perpendicular alignment of the support is now possible with the first and the second adjustment means.
  • a third adjustment means and a fourth and fifth adjustment means may be arranged substantially vertically spaced from the third and from each other horizontally.
  • the vertical and horizontal distances of the third, fourth and fifth adjusting means are each again 20 to 100 mm.
  • Third, fourth and fifth adjustment means may e.g. be arranged in the form of an L or T, the former embodiment is more advantageous, since then purely horizontal (rotation) and vertical effects are possible on the support.
  • one or more pressure means act on two adjacent sides of the sleeve substantially centrally on the support, so that no shear forces are imparted to the support by the action of the adjustment and the pressure means.
  • adjustment preferably screws are used because with these a particularly simple and sensitive adjustment of the support is allowed.
  • the position of the adjusting means can be advantageously determined by suitable fixing means. A particularly simple fixation of screws can be achieved with the help of lock nuts.
  • the adjusting means can be set independently, as each perpendicular to this adjustment means on an adjacent side of the sleeve arranged pressure means allow movement of the support perpendicular to these pressure means.
  • Fig. 1 shows in a purely schematic representation of a detail of a device 1 according to the invention for supporting, stacking and transporting kiln with a support 2 and a sleeve 3.
  • the adjusting means 4, 4 ' are each vertically above each other, approximately at a distance of 50 mm, and arranged centrally with respect to sleeve 3 and support 2.
  • the adjustment means 4" is arranged centrally in the base of the sleeve.
  • the adjustment means 4, 4 ', 4 "screws which are rotatably mounted in the sleeve 3.
  • Fig. 2 shows a vertical section through the device 1 according to the invention in a plane perpendicular to the plane of representation of Fig. 1 and on the opposite side of the screws 4, two coil springs 6 are arranged in the sleeve 3. Between the screws 4, 4 ', 4 "and the coil springs 6 and the support 2 are pressure plates 7, 8, 9 arranged to punctual pressure voltage peaks on the support 2, which are usually made of ceramic material such. As Al 2 O 3 , RSiC, SiSiC, NSiC or mullite is to be avoided.
  • pressure plates 7, 8, 9 are preferably made of steel and can be mechanically connected by suitable means (not shown) with the screws 4, 4 ', 4 "and the coil springs 6, so that the position of the pressure plates 7, 8, 9 with respect to the associated screws 4, 4 ', 4 "and coil springs 6 in a horizontal or vertical adjustment of the support 2 is not changed.
  • suitable means not shown
  • the sleeve 3 made of steel, but it may also consist of a different material, such as ceramic, aluminum, Ti alloy, etc. ..
  • the sleeve 3 made of steel, but it may also consist of a different material, such as ceramic, aluminum, Ti alloy, etc. ..
  • For thermal and mechanical decoupling of the sleeve 3 of the support 2 layers of z Hard fiber or a mica layer press between support 2 and the pressure plates 7, 8, 9 may be arranged
  • FIGS. 2 and 3 show that the screws 4, 4 'act in direct action line on corresponding coil springs 6 and so the support 2 is elastically fixed in the sleeve 3 and also an entry of shear forces is prevented.
  • a thermal expansion of individual parts of the Brennwagen preliminarys is by the coil springs. 6 elastically balanced, so that the determination of the support 2 in the sleeve 3 is permanently retained even after several heating cycles.
  • the pressure plates 7, 9 not only pressure voltage peaks are kept away from the support 2, but a flat and thus defined effect of the screws 4, 4 'and 6 ensures coil springs on the support 2.
  • the support 2 which is designed as a hollow Vierkantor, but also may be solid, spatially adjust and fix two pairs of screws both on all sides perpendicular and in the horizontal and vertical.
  • a vertical pair of screws 4, 4 ' are replaced by three screws, which are arranged substantially in the form of an L or T or a vertically mirrored shape, wherein z. B. two screws are arranged horizontally in a plane and symmetrical to the sleeve wall center and the third screw to vertically above or below spaced and arranged in the sleeve center.
  • rotation of the support 2 can be adjusted about its lateral axis. This is particularly advantageous if two supports are to be aligned with each other.
