Definitions

  • the invention relates to a device for holding a ceramic tube, in which the tube is held and hangs at its upper end during firing.
  • Pipes cannot be burned in an oven, for example an electric oven, either standing or lying, as they will warp. Pipes are therefore burned hanging.
  • the tubes are made in excess length.
  • the top of the pipe is provided with holes through which a ceramic rod is pushed. This is inserted into the device so that the tube hangs around the axis of the rod.
  • the holes must be exactly perpendicular to the longitudinal axis of the pipe, otherwise the pipe will hang at an angle in the device, which can also lead to warping.
  • the holes have been observed to occasionally break out or tear off the pipe or rod. Ultimately, this is due to the fact that the bearing points that the holes offer are comparatively small.
  • the object of the invention is to propose a device of the type mentioned by which the hanging of a tube is improved during the burning process.
  • the above object is achieved in a device of the type mentioned in that a stone is provided which surrounds the upper end of the pipe, that a compensating joint between the stone and the pipe is filled with mortar that the stone on supports at the bottom of the Device is stored and that the tube is placed directly or indirectly on the floor.
  • the tube When equipping the device, the tube is placed between the supports. The stone grips the upper end of the pipe. The mortar has not yet hardened.
  • the tube shrinks when firing begins.
  • the mortar gradually hardens.
  • the pipe is clear of the ground, so that it now hangs on the stone using the mortar.
  • the pipe assumes a vertical position under its own weight as long as the mortar has not yet hardened. After the mortar has hardened, the pipe is held securely in its vertical position.
  • This device has the advantage that the tube does not have to be made in excess length. It is not necessary to have a hole with holes that has to be cut off after firing. The pipe is kept non-destructive in the facility.
  • the stone for receiving the tube has an opening which widens conically, preferably upwards, and at its narrowest point matches the tube diameter. On the one hand, this promotes the vertical leveling of the pipe and, on the other hand, a tight grip around the pipe is guaranteed even before the mortar has hardened.
  • An at least simply split formation of the stone serves to simplify the attachment and removal of the stone.
  • the stone parts can then be pushed radially to the longitudinal axis on the pipe. They can be easily removed after burning without damaging the pipe.
  • Supports 2 are stacked on a floor 1 of the device. Between the supports 2 there are shafts 3 for receiving ceramic, still unfired tubes 4.
  • a stone 5 is provided for hanging each tube 4. This consists of two identical stone parts 6, 7.
  • the stone parts 6, 7 are placed on the supports 2 and pushed to the upper end 8 of the tube 4.
  • the stone parts 6, 7 form an opening 9 in the pushed-together position. This is adapted at its narrowest point 10 to the outer pipe diameter. It widens conically from the narrowest point 10 so that a space 11 is created as a compensating joint between the tube 4 and the stone parts 6, 7. This free space 11 is filled with mortar 12.
  • the tubes 4 are of different lengths.
  • the shorter, right tube is accordingly on a higher support body 13 than the left tube.
  • the burning process takes place.
  • the pipes 4 thereby shrink. Since they are held at the top by the stone parts 6, 7 or the mortar 12, the shortening in length has the effect that the pipes 4 are released from the support bodies 13.
  • the tubes 4 are placed under their own weight in an exactly vertical position.
  • the not yet fully hardened mortar 12 in the free space 11 permits a corresponding movement of the upper end 8 of the pipe 4.
  • the stone parts 6, 7 and the mortar 12 can simply be knocked off the pipe 4.
  • the stone parts 6, 7 can be used for further firing processes.
