Definitions

  • the invention relates to a fastening device for electric radiators on lining blocks of a furnace, lining blocks standing one above the other being connected to one another by means of hooks engaging therein and the radiators, such as heating spirals or heating tapes, being laid on the inside of the furnace.
  • the object of the invention is to propose a fastening device of the type mentioned, which is inexpensive and with which the radiators are easy to assemble.
  • the above object is achieved in a fastening device of the type mentioned at the outset in that a rod is placed on the side facing away from the inside of the furnace, the rod running approximately parallel to the inside of the furnace, that brackets are attached to the rod, which extend to the inside of the furnace, and that receptacles for holding the radiators are formed on the brackets on the inside of the furnace in front of the lining blocks.
  • the bars can simply be placed between two rows of lining blocks.
  • the brackets are attached to the rods, preferably hung.
  • the radiators can then be inserted into their pictures.
  • the rod lies securely between the lining blocks. It cannot break out.
  • the anchors keep it from slipping.
  • the rod preferably consists of a ceramic tube. At the same time, it forms the electrical insulation between the radiators and the retaining anchors or the furnace wall.
  • the cross section of the rod is preferably round and the stirrups overlap the rod.
  • the brackets thus exert a pressure on the fiber block under the weight of the radiators towards the outer wall of the furnace. This further reduces the risk of lining block breakouts.
  • the radiators held by the holders are in front of the inside of the stove. This improves the electrical efficiency. To further improve the efficiency, a distance is formed between the receptacles and the lining block in an embodiment of the invention.
  • Holding anchors 2 are attached to an outer wall 1 of the furnace and have tips 3 pointing up and down.
  • the tips 3 of a holding anchor 2 engage in two stacked lining blocks 4, which e.g. are folded from ceramic fiber mats.
  • the lining blocks 4 are thereby held on the outer wall 1 of the furnace.
  • Brackets 7 are hung on each of the rods 6. These consist of a heat-resistant round steel. The bracket 7 engages around the rod 6 with a bent end 8. It extends towards the inside 5 of the furnace.
  • the bracket 7 initially runs obliquely downward from the rod 6.
  • an incision 9 is provided in the lining block 4 between the holding anchors 2. Outside the incision 9, the bracket 7 is provided with a downward bend 10, which bears against the lining block 4.
  • a receptacle 11 is formed at the lower end of the bend 10. This is approximately halfway up the lining block 4.
  • the receptacle 11 is formed by a bend in the bracket 7.
  • a heating coil 12 is inserted into this.
  • a bracket 7 is shown in FIG. 1 for the uppermost lining block 4, on the bend 10 of which three receptacles 11 for heating spirals 12 are formed.
  • the bracket 7 is provided between its bend 10 and its receptacle 11 with a further bend 13, which forms a distance between the receptacle 11 and the lining block 4.
  • the receptacle 11 is designed for a heating tape 14. Because of the bend 13, the heating tape 14 does not touch the lining block 4.
  • the rods 6 are placed behind the tips 3 and the brackets 7 are hung on the rods 6.
  • the heating coils 12 or the heating strips 14 are placed in the receptacles 11.
  • the bends 10 are pressed against the lining blocks 4 by the weight of the heating coils 12 or the heating strips 14, since the brackets 7 are movable on the rod 6 in this respect.
  • the lining blocks 4 are pressed together. In particular, this prevents the inner surfaces of the lining blocks 4 from tending to break open. In this respect, the fastening device does not stress the lining blocks.
  • the electrical insulation of the heating coils 12 or heating tapes 14 with respect to the holding anchors 2 and thus the outer wall 1 of the furnace is ensured by the non-conductive rods 6. Since the heating coils 12 or heating tapes 14 are essentially free in the furnace, the risk of overheating of the lining blocks 4 and the heating element is low.
