Definitions

  • the invention relates to a transport path in a tunnel furnace for firing ceramic material, with which sled for transporting the ceramic material are guided through the firing channel of the tunnel furnace, the transport path consisting of rolling plates arranged in the longitudinal direction of the firing channel, which are provided with channels and pick up the balls for carrying and transporting the sled.
  • DE-OS 22 20 392 describes such a transport path in which the balls carrying the slides are guided through the combustion channel with the sled. The balls are placed on the unwinding plates at the entrance of the firing channel and removed from the unwinding plates at the exit of the firing channel and transported back to the entrance of the firing channel for reuse.
  • the balls are also exposed to a strong temperature change, which has a negative effect on the life of the balls.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of creating a transport path in a tunnel kiln for firing ceramic material, in which the balls used for carrying and conveying the sled are subjected to approximately a constant temperature depending on the location in the firing channel .
  • the balls run in the oval-shaped channels and remain at the intended location in the area of a rolling plate, the balls are subjected to a constant temperature effect, so that the life of the balls reaches a higher value.
  • Another advantage is that a smaller number of balls can be used. This means that expensive, high-temperature material and cylindrical grinding can be saved. The investment costs are therefore lower.
  • a transport path 1 is shown in the figures, which can be arranged in a tunnel furnace for firing ceramic material.
  • the conveyor track 1 consists of two rows 2 and 3 of adjacent rolling plates 4, which are arranged at a distance A from each other.
  • the rolling plates 4 are arranged inclined at an angle B with respect to the horizontal towards the inside of the transport path 1.
  • the rolling plates 4 rest on supports 9 which have bearing points 10 which are inclined according to the angle B and which accommodate the rolling plates 4.
  • the supports 9 are located on the floor or bottom channel of the combustion channel. The supports 9 and the rolling plates 4 can be easily replaced, depending on the load.
  • Each rolling plate 4 has a groove 5 on the top, which runs in the form of an oval.
  • the channels 5 take up balls 6 which roll in the channels 5 in a concentric manner.
  • the balls 6a located in the inner region 4b of the transport path 1 or the channels 5 carry slides 7 which have approximately a trapezoidal shape which corresponds to the inclination of the rolling plates 5.
  • the flanks 7a of the carriage 7 form a flat angle C with the inclination of the rolling plates 4, so that only the balls 6a located in the inner region 4b of the transport path 1 come into contact with the carriage 7, while the other balls 6 freely load into the Run around channels 5.
  • the balls 6 and 6a Due to the movement of the carriage 7 in the direction of arrow D, the balls 6 and 6a are kept in constant circulation in the channels 5 from the inner region 4b of the transport path 1 into the edge region 4a and from there again into the inner region 4b of the transport path 1 . Once the balls 6 out of the interior 4b have reached the outer region 4a, the balls 6 automatically roll back into the inner region 4b, since they are not loaded by the carriage 7, since the channel guide in the edge region 4a has a slight inclination to the channel guide in the inner region 4b.
  • the individual rolling plates 4 can be arranged in rows 2 and 3 with gaps one behind the other in order to absorb the expansion that occurs as a result of the temperature effect.
