Definitions

  • the invention relates to a holder for stone slabs of an incinerator for example a waste incineration plant, with a support for supporting a stone slab and a plate-shaped one that can be hung upright in the carrier Tab to hold the framed stone slab.
  • the boundary wall of a waste incinerator usually consists of a pipe wall and curtain-resistant, fire-resistant stone slabs, for example Silicon carbide.
  • the connecting the individual parallel tubes Metal wall sections are also called tubular fins, to which massive holders of the type mentioned at the beginning (G 90 16 206.4) to support and maintain the Stone slabs are attached. Because the furnace wall a variety of stone slabs shows, the welding of the numerous supports proves to be a very time-consuming operation.
  • the holder recesses can be provided, in which the tabs for the purpose Maintaining the stone slabs are embedded. Such recesses reduce the plate thickness required to protect the pipe wall.
  • the trapezoidal support the holder according to DE-40 07 662 C1 is difficult to attach to the pipe fins weld on.
  • the holder requires large recesses in the Stone slabs.
  • the invention has for its object to the holder mentioned improve.
  • the Carrier is a bolt, one at its end facing away from the welding foot has upright hook for reaching behind the hooked tab, and that the tab has two aprons, which with the tab attached under the bolts reach down. Since the shape of the beam is reduced to a bolt, the required cutouts in the stone slabs are kept smaller, what improves its protective function and reduces the risk of corrosion of the pipe wall. Furthermore, there is the great advantage that the carrier in the stud welding process the metal wall can be welded on, fixing the working time the numerous supports on the metal wall are significantly shortened. The one from the tab descending aprons are sufficient, the stone slab from above against the Maintain metal wall that is below the stone slab supported by the bolt located.
  • the bolt has one in front of the hook Notch corresponding to the strength of the tab. This will win the tab a defined position on the bolt during assembly, so that the Placing the stone slab on the bolt is facilitated. They are useful opposite side parts of the tab relative to the die The middle part of the flap connecting the side parts is folded, which results in a Reduction of the lateral recesses of the stone slab can be achieved. Further it is recommended that the hooked tab is not or at least not significantly higher than the height of the hook. This measure also leaves the cutout in the stone slab is small for the tab.
  • the hook in the of the chamfered side panels is defined space and the aprons are not reach further under the bolt than the tab rises above the bolt, can the recesses required for the holder in the stone slabs above and below are shaped symmetrically, which is the manufacture of the stone slabs simplified and counteracts the risk of cracking in the stone slabs.
  • the welding of the bolt to the metal wall must do the considerable thing Weight of the stone slabs without risk of breakage despite the eminent thermal Can take a load.
  • a bolt that is in preferred embodiment of the invention as a cross-sectional shape an upright represents a standing rectangle, in particular of 15 x 8 mm. It is also recommended the part of the recesses in the stone slabs on the combustion chamber side a wool, a ceramic tile or a glued, air-permeable Lining the thermal insulation layer, thereby additionally a scaling of the Counteract holder.
  • the holder 1 consists of a bolt 20 and one suspended in the bolt 20 Tab 30.
  • the bolt 20 has a shaft 21 with a front welding foot 22 and an upright hook at the end facing away from the welding foot 22 25 on.
  • the cross-sectional shape of the shaft 21 is an upright rectangle with the external dimensions 15 x 8 mm.
  • the shaft 21 has a Notch 23, the width of the thickness of which is taken in the longitudinal direction of the shaft Middle part 35 corresponds to the tab 30.
  • the essentially plate-shaped tab 30 consists of two opposite side parts 32, 34 and the middle part 35 connecting them.
  • the side parts 32, 34 are relative to the central part 35 in the same direction and in essentially folded by the same amount.
  • the middle part 35 has from its underside a cutout 36 of a width that the thickness of the Shaft 21 corresponds, that is little larger than 8 mm. This makes everyone Side apron 37, 39 each formed a descending.
  • the Tab 30 hung in the pin 20 in the manner shown in FIG. 1, the middle part is held in the cutout 36 and the two side parts 32, 34 define a space between them in which the hook 25 is recorded.
  • the aprons 37, 39 then extend so far under the shaft 21, how the middle part 35 and the two side parts 32, 34 over the shaft 21 raise. It can also be seen from FIG. 1 that the side parts 32, 34 and the middle part 35 are only slightly higher than the hook 25.
  • the shaft 21 with its welding foot 22 through Stud welding is welded to the tube fin 3, which only takes a short time.
  • the tab 30 can then be used to prepare for the construction of the stone slab wall be hung in the holder in front of the pipe wall 2 as explained.
  • the upper stone slab 6 has a recess 15 opening approximately in the middle of its underside, in which the upper part of the tab 30 and the hook 25 are to be accommodated. How Figure 5 shows, the recess 15 has a width which is slightly larger than that Width of the tab 30.
  • a cutout 18 in the underside of the stone slab 6, which sits on the shaft 21, extends from the inside 11 to the recess 15. The depth of the cutout 18 can be approximately half the height of the shaft 21 correspond.
  • the lower stone slab 7 has an opening approximately in the middle of its upper side Recess 16 in which the aprons 37 and 39 find space. Like Figure 6 shows, the recess 16 has a width which is slightly larger than the width of the Tab 30. A cutout 13 in that receives the lower half of the shaft 21 the top of the stone slab 7 extends from the inside 17 to Recess 16.
  • the cutout 18 and the recess 15 are symmetrical to the cutout 13 and the recess 16.
  • the aprons 37 and 39 When building the stone slab wall, the aprons 37 and 39 initially hold the lower stone slab 7 by their engagement in the recess 16 against the Pipe wall 2 at. In the combustion chamber-side part 14 of the recess 16 becomes a wool or the like air-permeable thermal insulation material introduced, which is on the side facing away from the tube wall 2 of the Hook 25 and the aprons 37, 39 is located. Then the upper stone slab 6 placed on the shaft 21 of the holder, so that the cutout 18 on the latter rests. The hook 25 extending into the recess 15 and the upper part of the Tab 30 keep the stone slab 6.
  • Recess 15 is also a wool or the like air permeable Thermal insulation material introduced, which is on the pipe wall 2 facing away from the hook 25 and the aprons 37, 39. Finally the outer joint 10 between the upper stone slab 6 and the lower stone slab 7 groomed.
