Definitions

  • the invention relates to a cover device, preferably for media supply openings in heating trains of coking furnace batteries.
  • the vertical heating cables of coke oven batteries have one or more openings on their sole for supplying the combustion media and openings on their upper end for removing the exhaust gases.
  • inspection hole openings are arranged in the furnace ceiling, but these have only a relatively small diameter in comparison to the cross section of the heating train and also in comparison to the cross section of the media supply openings. After completion of the complete masonry of a heating wall, the heating cables are usually only from the outside
  • the object of the present invention is therefore to propose a cover device which can be lowered through the inspection hole openings into the vertical heating passages and ensures complete coverage of the media feed openings and can be pulled out of the heating train again through the inspection hole opening after completion of the repair work.
  • a cover device consisting of a) a horizontal base plate b) hinged to the base plate and foldable up and / or down cover plates and c) a vertically arranged actuating rod for lowering and raising the covering device.
  • the sub-claims 2 to 9 contain useful embodiments for this.
  • the covering device according to the invention with movably brought together iron parts creates the possibility that media supply openings on the heating soleplate, which are larger in size than the inspection hole openings arranged in the furnace ceiling, can be sealed.
  • Fig. 1 shows in section along the line A-A of Fig. 2, the covering device according to the invention as a whole.
  • Figure 2 is a top view.
  • FIG. 3a to 3e show the covering device in different
  • FIGS. 3b and 3c with cover plates 2, 3 folded out when sealing the media supply openings 18
  • the covering device consists of a base plate 1 to which 15 articulated rods 4 are fastened via horizontal axes of rotation. On these articulated rods 4, two cover plates 2 and 3 are also pivotally attached about their longitudinal axis.
  • the bracket 7 is slidably mounted with a horizontally arranged bolt 7a in an elongated hole guide 14 of the actuating rod 5.
  • the actuating rod 5 is suspended from a chain 8 with a suspension bracket 16 and is designed to be longitudinally displaceable relative to the base plate 1 and the guide sleeve 6 connected to it.
  • the actuating rod 5 projects with its lower end plate 12 below the base plate 1.
  • the base plate 1 slides further down with the guide sleeve 6 on the actuating rod 5.
  • the cover plates 2, 3 are also lowered at the same time and are released from the locking with the bolts 7b.
  • the pressure piece 9 moves with the guide pin 11 in the elongated hole 10 of the actuating rod 5 to the upper end of this elongated hole and pushes the flaps 2, 3 outward during further displacement, so that they fall onto the media feed openings.
  • the displacement of the actuating rod 5 with respect to the base plate 1 ends when the end plate 12 is arranged in the recess 13 in the base plate.
  • the arrangement of the end plate 12 in the recess 13 prevents the actuating rod from being pulled out of the covering device as a whole.
  • the device After completion of the repair work, the device is lifted with the help of the chain 8, so that the cover plates 2, 3 fall down into a vertical position (see FIGS. 3d and 3e) and can be easily removed from the oven through the inspection hole openings.
  • the cover plates 2, 3 In order to achieve the best possible sealing of the media supply openings 18, the cover plates 2, 3 have soft seals 17 at their edges, for example made of fiberfrax.

Abstract

L'invention concerne un dispositif de recouvrement, de préférence pour les orifices d'alimentation des carneaux de chauffage des batteries de fours à coke. Ce dispositif est rabattable pour qu'il soit possible de le passer par une petite ouverture et déployable pour qu'il puisse recouvrir un ou plusieurs orifices plus grands. Ce dispositif est constitué a) d'une plaque de base (1) horizontale, b) de plaques de recouvrement (2,3) articulées sur la plaque de base (1) et rabattables vers le haut et/ou vers le bas, et c) d'une barre de commande (5) verticale servant à abaisser et à soulever le dispositif de recouvrement. L'invention est également caractérisée en ce que la barre de commande (5) est disposée de manière à être mobile dans le sens de son axe longitudinal par rapport à la plaque de base (1).
