Definitions

  • the invention relates to a device for holding electrical, meandering heating conductors at a distance from the hot side of the side walls of an insulating body made of ceramic fibers in industrial furnaces, the heating elements in the areas of their upper and lower deflections of metallic anchors arranged on the insulating body, in particular made of wire sections. are held, the anchors also having console-like supports, which strut laterally from the anchor shafts and can be placed on the hot side of the insulating body, and the supports of the respective upper anchors are each formed by a downward-directed bend adjoining the anchor shaft.
  • each of the two legs of the load hook-like bends has a relatively large length in order to be able to hold the heating conductor even if the latter heats up to operating temperature, e.g. to 1000 ° C more.
  • the metallic anchors When the heating conductor is heated, the metallic anchors also heat up accordingly. It has been shown, however, that the e.g. Deformed to 1000 ° C and possibly more heated anchors already by their own weight that afterwards a correct and positionally secure mounting of the heating conductors is no longer possible, although the anchors consist of high-alloy, high-temperature-resistant metal.
  • the invention is based on the object of improving a device of the type specified in the preamble of claim 1 in such a way that at least while maintaining the advantages given in the prior art, a substantial simplification and reduction in price of the device itself and its manufacture and its assembly can be achieved.
  • the supports of the lower anchors are each designed as a straight rod running parallel from the anchor shaft to the leg, and furthermore the support designed as a rod is welded to the anchor shaft.
  • bracket-like support by a laterally striving folding of the anchor shaft.
  • a further advantageous embodiment in the sense of the object of the present invention is characterized in that an angle piece forming the support is fastened to the anchor shaft, one leg of the angle piece abutting the anchor shaft, the other angle piece leg, however, being aligned with the bent armature leg and arranged at a parallel distance.
  • the angle piece can advantageously be attached to the anchor shaft by welding.
  • the anchor on the anchor shaft Leg of the elbow has the anchor shaft encompassing brackets that can be integrally formed on the elbow.
  • Another one-piece design of the prescribed anchor is that a bend forming the support is arranged on the anchor shaft, which is followed by a section running approximately parallel to the anchor shaft towards the free end of the armature, from which the aforementioned bend opposes the one holding the heating conductor Leg is bent.
  • FIG. 1 two successive anchors 3, 3 'made of heat-resistant metal for holding the heating conductor are shown in an insulating body 1 made of ceramic fibers in the longitudinal extension of a meandering heating conductor 2.
  • the anchors each attack the bends of the heating conductor 2.
  • the shafts 4, 4 'of the anchors 3, 3' are directed at right angles to the hot side 5 of the insulating body 1 and are embedded in the insulating body 1 in a manner which is virtually non-detachable.
  • the legs 6, 6 ', on which the bends of the heat conductor 2 are supported or which overlap the bend of the heat conductor 2, are directed in opposite directions.
  • the leg 6 of the armature arranged at the top in FIG.
  • the leg 6 'of the armature 3' lying in the drawing figure 1 is so long that the heating conductor 2 heated to the operating temperature, the length of which increases in the process, can move along the leg 6 'and is still held securely.
  • the anchors 3,3 ' are made in one piece from wire sections of circular profile. Their shaft parts engaging in the insulating body 1 have protrusions, not shown, which project laterally and which secure the anchors 3, 3 'both against rotation about their longitudinal axis and in the direction of the longitudinal extent in the insulating body 1.
  • the anchors 3, 3 'each have a bracket-like support 8, 8' resting on the hot side 5.
  • the support 8 'of the lower armature 3' is designed as a straight rod which extends in the same direction as the leg 6 'of the armature 3' and is oriented in the same direction and welded to the armature shaft 4 '.
  • the shaft of the upper armature 3 has a bend which is directed downwards at right angles and which bears on the hot side 5 of the insulating body 1 and forms a bracket-like support 8, to which a section 9 running parallel to the armature shaft 4 adjoins the free end of the armature 3 , from which the leg 6 is bent.
  • the support 8' is formed by a right-angled angle piece 10 'welded to the anchor shaft 4'.
  • the elbow leg welded to the armature shaft 4 ' runs parallel to the armature shaft 4', while the other elbow leg is arranged in the same direction as the leg 6 'of the armature 3'.
  • a U-shaped angle piece 10 ' is welded to the armature 3' to form a support 8 ', both angle piece legs being oriented in the same direction as the leg 6' of the armature 3 '.
  • the support 8' is formed by folding the armature shaft 4 'in the same direction as the leg 6' of the armature 3 '.
