Definitions

  • ABSTRACT A support formed of modular elements made of refractory material. Each modular element is a rectangular case open at both ends and having horizontally extending teeth projecting from the inner and outer faces of two vertical sides. The teeth are adapted to carry horizontal plates upon which products to be baked are supported while the support moves through a furnace. Plate-like interconnecting elements are provided for assembling the modular elements.
  • toothed boxes arranged in coaxial rows and possibly superimposed one upon another, are supported by a loading platform formed of suitable carriages. After the boxes are filled with the ceramic products to be baked, they are moved to the furnace.
  • the carriages pass through the tunnel of the furnace in a predetermined time sufficient to bake the ceramic products being transported.
  • the actual baking method mentioned above entails some drawbacks resulting from the structure of the toothed boxes. Due to their shape, when the boxes are arranged in coaxial rows, they form cuniculi with a quadrangular cavity and a length generally equal to the length of the carriage platform. The cuniculi are longitudinally subdivided in spaces delimited by the parallel refractory plates which support the products to be baked. The hot air circulates through these spaces in an insufficient manner, so that while the ceramic products facing the opposed ends of the cuniculi which contain them are subjected to a mass of hot air sufficient to completely bake them, complete baking of the ceramic products located towards the center of said cuniculi, namely, in the innermost zone of the corresponding alveoli does not occur. In effect, in the innermost zone the thermal transmission is insufficient, and therefore it is necessary to extend the time each carriage remains within the furnace, with a considerable waste of ther- W mal energy and without the complete elimination of the risk of incomplete baking for some ceramic products.
  • the main object of present invention is to provide toothed supporting cases, made of a refractory material, for ceramic products and particularly for glazed products to be submitted to a single-baking.
  • the cases are formed by modular elements which can be assembled and made interdependent by removable interconnecting members which provide wide empty zones through which the hot air of the furnace circulates freely. As a result, all the ceramic products are subjected to the hot air regardless of where they are located with respect to the longitudinal order of the supports on which they are carried.
  • Another object of the invention is to reduce the weight of the supportingframes for the ceramic products, that is, to attain a reduction of the passive load located within the furnace and to correspondingly increase the useful load, the total weight being equal as compared to the known toothed boxes heretofore used.
  • Still another object of the invention is to provide refractory supports of variable length resulting from the assembly of more or fewer of the modular elements forming the supports.
  • a further object of the invention is to provide refractory supports comprising plates which may be superimposed, with dimensional tolerances considerably smaller between the various elements, due to the reduction of the length of each box.
  • the subject matter of the invention is a support, made of refractory material, for the baking of ceramic products, particularly but not exclusively glazed products, characterized in that the support is formed by cases having sides which constitute modular elements which may be assembled in longitudinal batteries; the batteries may be superimposed.
  • the modular elements are interconnectable by the use of separate removable interconnecting elements suitable to effect the formation of supporting frames of refractory material.
  • the supporting frames comprise spaces occupied by parallel and superimposed bearing plates for the ceramic products, alternating with vacant or partially vacant spaces, suitable to allow the free circulation of the air within the furnace and, hence, the best thermal distribution with respect to the ceramic products being baked.
  • FIG. 1 shows three superimposed modular elements
  • FIG. 2 illustrates one of the many possibilities of the modular element assembly according to the invention.
  • FIG. 3 illustrates one of the possible embodiments of the interconnecting element for removably interconnecting a plurality of cases.
  • each toothed case 5 comprisrs a preferably quadrangular frame, of a refractory material, with open ends 6 and vertical sides 7 provided with longitudinal outer teeth 8 and inner teeth 9, symmetrically arranged on the opposite faces of each side.
  • Each series of outer teeth begins and terminates, considering the outer face of each vertical side of each case 5, with two teeth 10, 10a, having a substantially tileshaped profile.
  • the profile defines a cavity suitable to accommodate the half-profile 11 or 11a of one of the terminal side edges of an element 12 (FIG. 3) made of a refractory material.
  • element 12 When element 12 is mounted together with cases 5, as shown in FIG. 2, it provides an intermediate connection between four toothed cases 5 substantially arranged at the vertices of a cube.
  • each connecting element 12 is preferably substantially plate-like and provided with a wide central aperture 13 for the circulation of air and with opposed intermediate edges 14 which fit between the edges of two, three, or four cases 5.
  • each connecting element 12 is the perfectly symmetrical structure of it, due to which the element does not require any particular mounting position with respect to cases 5 and therefore, once arranged in its horizontal position it stated features.
  • a support for holding ceramic products during baking comprising:
  • a. a plurality of open-ended rectangular cases each having a top wall, a bottom wall, and two vertical side walls,
  • each of the extreme, upper. and lower teeth of each outer series of" teeth being profiled to define, to-
  • a plate-like connector element having two parallel side edges, the end portiop cf each of said edges being profiled to be accommodated by one of said cavities and not removable from said cavity by rela:
  • each of said cavities has a T-shaped cross-sectional shape
  • each of said end portions of said connector element two successive cases in each row, so as to space said cases apart.
