Definitions

  • This patent application involves a tool for lining the ceramic insulation layer applied to the interior walls of ovens.
  • Conventional ovens have a composite structure consisting, from exterior to interior, of a metal support casing, a layer of refractory material and an insulation layer that is generally in ceramic.
  • ceramic insulation material on the interior walls of the oven is particularly critical in that the fumes strike the ceramic at very high temperatures causing the ceramic to flake, so that fine particles of material peel off the surface and are carried by the fumes outdoors where they pollute the atmosphere.
  • the scope of this invention is to permit lining, with refractory material, the interior ceramic layer of pre modification ovens without the specific support framework in refractory material.
  • the tooling according to the invention consists of cell-like plates in refractory material and screws or pins also realised in refractory material for securely fixing said refractory plates against the internal face of the ceramic insulation layer on the side walls and top of the oven.
  • the refractory cell-like plates are fixed on the ceramic insulation layer by means of screws, also realised in refractory material.
  • the screws support its relevant weight entirely so that in this case it is preferable not to use self-threading screws but bolts in refractory material and respective nuts.
  • the length of the bolts must be sufficient to pass through the ceramic layer as well as the conventional refractory lining on the exterior of said ceramic layer - both pre-drilled - so that the relevant nut may be fitted on the respective shank, namely at the space between the exterior refractory layer and the support casing of the oven.
  • a second construction version involves cell-like refractory plates fixed against the ceramic layer by means of special refractory pins, that are fitted in pre drilled holes on the ceramic layer itself as well as on the most conventional exterior refractory layer.
  • Each of the pins is characterised by a wide circular head and a smooth shank terminating with a short hooking eyelet for a fork terminating at the top with a threaded shank screwed to a plate having a central threaded hole positioned - in the same way as for the nuts of the previous fixing technique described - between the support casing of the oven and the refractory layer on the exterior face of the ceramic insulation layer.
  • the structure of the side wall of an oven generally has a metal support casing (1) - in the case in question, consisting of series of metal vertical profile sections - on the exterior of this casing; the casing (1) having a layer of panels in refractory material (2) as well as a series of blocks (3) made of insulating ceramic material fixed to the support casing (1) by means of suitable hooks (4).
  • the cell-like plates (5) made of refractory material according to the invention being fixed on the interior face of said ceramic blocks (3).
  • said plates (5) have a central hole in which a self-threading screw (6) made of refractory material is fitted and having a wide polygonal head (6a) whose threaded shank is screwed and fixed into the body of the ceramic block (3) immediately behind the respective refractory cell-like plate (5).
  • Figure 2 refers to a section of an oven top; said top also consists of the conventional support casing, which in the case in question, consists of metal studs (7a) and panels (7b).
  • a layer of refractory panels (2) is also fixed on this section of casing (7) as well as a series of ceramic insulating blocks (3) fixed to the support casing (7) by means of corresponding hooks (4).
  • the cell-like refractory plates (5) according to the invention abut against the interior face of said ceramic blocks (3).
  • said plates (5) are fixed by means of refractory wide-headed bolts (8) fitted into corresponding vertical-axis holes in the ceramic blocks (3) and the refractory panels (2) furthermost from these.
  • Figure 3 is similar to figure 2 with the difference that in this case each of the cell-like plates (5) is fixed to the interior face of the ceramic insulation block (3) behind the same by means of a smooth-shanked refractory pin (10) with wide circular head (10a) also fitted into a corresponding vertical-axis hole in the ceramic insulation layer and the furthermost refractory layer (2).
  • a smooth-shanked refractory pin (10) with wide circular head (10a) also fitted into a corresponding vertical-axis hole in the ceramic insulation layer and the furthermost refractory layer (2).
  • each pin (10) features an attachment eyelet (10b) at the end of its shank for a fork (10c) terminating at the top with a threaded shank (10d) that screws to a polygonal plate (11) having a central threaded hole positioned behind the above refractory panelling (2).
