Definitions

  • This descriptive report refers to a DRAIN SYSTEM FOR REFRACTORY SHELVES, which is intended for drainage of metal and other leaks in the liquid state during their transport by means of refractory ducts, whether heated or not, and can be used in various types of refractory gutters, support of plating and insulation and in the various sectors of the industries of processing and processing of metals and others.
  • REFRAT ⁇ RIAS aims to form a safe, practical and efficient means for the drainage of leaks of metals and others, in the liquid state, during their transport that is effected by refractory gutters, which are united by means of seals.
  • the refractory ducts are arranged on a metal structure which covers them in all their extension.
  • Liquid metal leakage mostly occurs at the point where the seals are applied to join the refractory gutters, entering and propagating through the insulation layers and damaging the refractory gutters.
  • the DRAINING SYSTEM FOR REFRACTORY PITCHES has been devised, which provides an efficient drainage system by means of a collecting drawer applied to specific points of the metal support, passing through the insulation layers and being disposed below the refractory gutters, so as to cover the full extent of the seals applied at the junctions of the refractory gutters.
  • This leakage containment and drainage system is preferably made by a collector drawer provided with a monitoring sensor system disposed at the end of its base which, upon contact with liquid metal, emits an alert which may be sent by means of electronic messages or triggered by panels or by any other means desired.
  • This drainage system for refractory gutters may be installed in new or operating conveyor lines, regardless of the type or models of refractory gutters.

Abstract

L'invention a été mise au point pour éviter que des fuites de métaux à l'état liquide pénètrent dans les matériaux isolants et endommagent les rigoles réfractaires, les dirigeant vers l'extérieur du système, et comprend un système de tiroirs collecteurs (1) pourvus d'un canal de drainage (2) où sont installés deux capteurs de surveillance (3), le tiroir collecteur présentant de préférence une forme rectangulaire, avec une longueur légèrement supérieure à la largeur de la rigole réfractaire (4), sa largeur étant dimensionnée pour couvrir les jonctions des rigoles et la zone des éléments d'étanchéité, sa hauteur étant dimensionnée pour s'étendre au-delà de la couche d'isolants (6) et du support métallique (5), de manière que le canal de drainage (2) où sont installés es capteurs de surveillance se trouve sur le côté extérieur du support métallique, des ouvertures (8) permettant un accès en vue d'un entretien interne des zones concernées par la fuite.
