Definitions

  • the invention relates to a firing aids for the single-layer firing of ceramic moldings in rapid-fire tunnel kilns with burners directed laterally against the burners standing on firing trolleys, consisting of vertical supports which project above the platform of the firing trolleys and are arranged at a distance from one another and on the free ends of which there are support elements for the moldings are put on.
  • the kiln furniture forms a free standing structure on the thermal insulation layer of the kiln platform, in which the supporting supports can be inserted into ladder-shaped supporting bodies and with which a freely standing on the weighing insulation layer of the kiln platform Form table construction.
  • the bars and rungs of these ladders form a wide-meshed grid on which the moldings rest.
  • This firing aid stock has proven itself for firing kemamic moldings which do not have to wave to the point of sintering; however, it is for firing thin-walled sintered products such as Stoneware tiles are unsuitable because the sintering process involves softening the body.
  • both sides of the heating gases blown under the fill at high speed after they have acted on the moldings also have to be dissipated below the moldings in the direction of the entry zone of the kiln cars in order to absorb their residual heat in the known configuration of the trimmings there is no possibility for this removal, since the continuous support strips block the removal of the heating gases below the moldings in the direction of the entry zone and drag them towards the cooling zone.
  • the invention has for its object to redesign the initially described training form of a kiln furniture so that a close-meshed support of the moldings, similar to that after the second-described training of the stock, arises and thereby an unhindered supply and discharge of the heating gases, also in the area below the moldings.
  • the support elements of the trimmings consist of crossbeams lying transversely to the direction of travel of the combustion vehicle with a multiplicity of slits open at the top, inclined to the vertical, and insertable support strips whose upper, saw-shaped incisions have edges that form the support grid for the moldings .
  • the slots each have an inclined and a vertical side wall, and the lower edge of the support strips facing the vertically extending side walls of the slots has transverse grooves, the bottom of which supports the bar on the vertical side wall of the slots, and the side walls of which bear against the outer sides of the crossbars .
  • the close-meshed support grate formed in this way for the underside of the molded articles is formed from the short sections of the edge sections between the saw-shaped incisions located at the top due to the inclination of the support strips, i.e. the molded articles do not lie on the upper side surface of the support strips, but only on them whose line-shaped edge sections, so that almost the entire lower surface of the molding can be acted upon by the heating gases.
  • the inclined position of the strips from both sides in the direction of the middle of the carriage favors the guidance of the gases coming from the side and from below against the underside of the moldings, the saw-shaped incisions forming transverse guide channels and promoting the swirling of the gas flows.
  • the one below the The large free cross-section formed between the support supports enables the heating gases to be distributed into the middle of the furnace space below the grate and discharged in the direction of the entry area of the kiln where they can give off their residual heat to the material moving towards the kiln.
  • incisions 1 a which here have an arch shape, are arranged on the top of the support strip 1 in a saw-like manner at regular intervals.
  • the flat parts of the upper parts of the support bar that remain between the incisions are designated 1b.
  • transverse grooves 1c are provided on one of the side surfaces.
  • the support strips 1 are inserted into the slots 3 of the cross bar shown in FIG. 2.
  • One side wall 4a of these slots is inclined and the other 4b is vertical.
  • the sections 4c of the upper side of the beam crossbar 4 between the slots 3 also run in an inclined direction. Stop cams 4d are provided on the underside of the beam traverse.
  • the support strip inserted into the slots 3 (cf. FIG.
  • the underside 1e of the support bar 1 is usually at a greater or lesser distance from the bed area 4e of the slot 3. The size of this distance depends on the depth T of the transverse groove 1c, ie the greater the depth of the transverse groove, the more the underside 1e of the support strip 1 approaches the bottom 4e of the slot 3, and section 4e of the top of the crossbar between the slots 5.
  • the depth of the slot 3 measured in the direction of the inclination of the side wall 4a is approximately 80% of the height of the Supporting strip 1. Depending on the operating conditions, a smaller percentage up to approximately 50% can also be selected.
  • the height of these edge sections 1f can, as can also be seen in FIG. 4, be changed by increasing the incision depth T of the transverse groove 1c, for example by grinding out the surface 1d forming the transverse groove base.
  • the support bar 1 then occupies a correspondingly lower position in the slot 3.
  • the support strip 1 is expediently placed on a support template inclined according to the selected angle of inclination and supported with the edge sections 1f forming the support grid against a fixed stop with a vertical contact surface and then with the template parallel to the plane of the bottom 1d of the transverse groove 1c below , r moved through a firmly adjusted grinding wheel.
  • the support supports 5 shown in FIG. 4 are designed as box sections that are open on both sides. On the outside of the upper wall 5a of the box there are three grooves 5b, the cross section of which is adapted to that of the crossbeams 4, while on the outside of the lower wall 5c of the box, which runs parallel to the side walls of the box, the opening planes of the box move inwards remote headers 5e are arranged.
  • the box-shaped support brackets 5 are, as indicated in FIGS. 5 and 6, inserted into ladder-shaped frames 7 resting on the platform 6a of the combustion vehicle 6, specifically with the plug-in strips 5e.
  • the Ealken raversen 4 lie in the grooves 5b on the top of the support brackets 5; they are (cf. FIG. 6) secured against displacement by the stop cams 4d which can be placed on the end faces of the upper walls 5a of the box section.
  • the box profiles are transverse to the movement indicated by a double arrow Direction of the fuel truck 6 extending, with openings directed to the side by means of the plug-in strips 5e inserted into the ladder-shaped frame 7, which are placed so that the ladder rungs 7a (FIG. 6) extend transversely to the direction of movement of the fuel truck 6.
  • the arrangement can be used to utilize the entire length of the kiln for the support surface so that, as indicated in Fig.
  • the outer support brackets are inserted into the ends of the ladder-shaped frame so that their respective outer wall facing the strinside of the car the end of the ladder is aligned, while the inner support brackets can be used to fix two abutting ends 7b of conductor sections 7 to one another by inserting one of the two plug strips 5a into one of the conductor ends.
  • the crossbars 4 can be inserted into the grooves 5b of the support brackets 5 in such a way that, as can also be seen in FIG. 5, they receive the crossbars 4 on the two end faces of the combustion vehicle 6 with the respective outer grooves 5b, while the internal support brackets 5 each with a beam crossbar 4 each with two external grooves 5b.
  • the support strips 1 inserted into the crossbeams can be placed butt-to-butt over the entire length of the platform of the combustion vehicle 6.
  • the ladder-shaped frame 7 is placed in such a way that the outer support brackets 5 receive the crossbeams 4 in such a way that they abut the inner support brackets abutting their outer walls with the stop cams 4d and over the outer ones lying support crossbars 5 with their end faces with the side surface 6b of the combustion vehicle 6 project approximately in alignment.
  • the stop cams 4d on the outer walls of the outer support brackets 5 and thus secure the crossbeams 4 en lateral displacement. From Fig. 6 the inclination of the support strips continues from both sides of the kiln Out the middle of the car.
