Definitions

  • This invention concerns apparatus for the gaseous treatment of solid materials particularly, though not exclusively, sintering apparatus, and being of the kind wherein a plurality of pallets each having a base in the form of a grate, are adapted to be moved in end-to-end abutting relationship through a treatment zone where a gaseous medium is passed through material on the pallets.
  • apparatus for the gaseous treatment of solid materials of the kind wherein a plurality of pallets each having a base in the form of a grate are adapted to be moved in end-to-end abutting relationship through a treatment zone where a gaseous medium is passed through material on the pallets, and provided with sealing means to ensure a seal between the sides of the pallets and the sides of means for the supply of treatment gas in the treatment zone, is characterised in that said sealing means comprise opposed slidably engaging sealing strips carried by the sides of the pallets and the sides of the means for supply of treatment gas respectively, there being longitudinally extending leaf springs sealably connecting the strips carried by one of these parts with the part and urging same into sealing engagement withthe opposed strips.
  • FIG. I shows a general arrangement drawing of the sintering apparatus
  • FIG. 2 shows an enlarged cross-section of the apparatus on the line II-II of FIG. 1;
  • FIG. 3 shows an enlarged fragmentary view of the sealing arrangements provided on the apparatus of FIG. 2 at the underside of the pallet;
  • FIG. 4 shows an enlarged fragmentary view of a modified sealing arrangement.
  • the apparatus comprises a plurality of pallets 10 which are adapted to be moved continuously on rails 11 around an endless path, having upper and lower runs.
  • the pallets are in end-to-end abutting relationship as they move along the upper run through a treatment zone defined between wind boxes 12 beneath the run and a hood 13 above the run.
  • each pallet has a base in the form or a grate 10a.
  • the pallets are equipped with wheels 14 which engage with the rails II.
  • the combustion air, supplied from the wind boxes 12 is constrained to flow upwardly through the grates 10a and hence through the material carried by the pallets, it is necessary to provide a seal between the sides of the pallets l0 and the sides of the wind boxes 12.
  • Each pallet is provided with flanges 15 which depend from opposed lateral sides of the grate 10a and terminate in spaced relationship from frame members 16 running along the sides of the wind boxes 12 and seals generally indicated at 17 are formed between these parts.
  • each flange 15 has a channel 18 therein which houses the upper crosssectional part of an elongated leaf spring 19 of generally S-shaped cross-section and which extends over the length of the side of the pallet.
  • the lower edge of the spring 19 has a strip 20 secured thereto and which is forced by the spring action into sealing engagement with a wear strip 21 carried by the frame member 16.
  • the seal may be modified as shown in FIG. 4, wherein a leaf spring 30 of generally L-shaped crosssection is secured by bolts 31 to the sides of the wind boxes 12, the upper longitudinal edge of the spring 30 having a strip 32 secured thereto which is urged upwardly into sealing engagement with a wear strip 33 secured to the base of the flange 15.
  • the sides of the pallets 10 may be sealed relative to the hood 13 by similar arrangements of leaf springs and slidably engaging sealing strips as generally indicated at 40 on FIG. 2.
  • Apparatus for the gaseous treatment of solid materials wherein a plurality of pallets each having a base in the form of a grate are adapted to be moved in end-toend abutting relationship through a treatment zone having means whereby a gaseous medium is supplied and passed through material on the pallets, characterized by means providing substantially gas tight sealing along the opposite sides of the pallets comprising at each side of each pallet opposed slidably engaging sealing strip means carried by respective parts on the sides of the pallets and the sides of the means for supply of treatment gas and additional seal means comprising longitudinally extending leaf springs, each leaf spring acting as a gas tight seal by sealably connecting the strip means carried by one of said parts with that part and resiliently urging the opposed strip means into sealing engagement, one with the other.
  • each pallet has opposed lateral flanges depending from its base, said sealing means being located between the lower edges of said flanges and the upper side edges of said windboxes.
  • leaf springs are of generally S-shaped cross-section and are secured by their own spring action to the lower edges of said flanges by having part of their cross-section located in channels in said lower edges.
  • leaf springs are of generally L-shaped cross-section and are secured to the upper side edges of said windboxes by bolts.
  • Apparatus according to claim 2 having a hood for collection of treatment gases disposed over the path of movement of the pallets in the treatment zone.
  • Apparatus according to claim having a hood for collection of treatment gases disposed over the path of movement of the pallets in the treatment zone.
  • Apparatus according to claim 7 having a hood for collection of treatment gases disposed over the path of movement of the pallets in the treatment zone.
  • Apparatus according to claim 8 including upper sealing means between the sides of the hood and the sides of the pallets, said upper sealing means comprising opposed slidably engaging sealing strips carried by the sides of the pallets and the sides of the hood respectively, there being longitudinally extending leaf springs sealably connecting the strips carried by one of these parts with the part and urging same into sealing engagement with the opposed strips.
  • Apparatus according to claim 9 including upper sealing means between the sides of the hood and the sides of the pallets, said upper sealing means comprising opposed slidably engaging sealing strips carried by the sides of the pallets and the sides of the hood respectively, there being longitudinally extending leaf springs sealably connecting the strips carried by one of these parts with the part and urging same into sealing engagement with the opposed strips.
  • Apparatus according to claim 10 including upper sealing means between the sides of the hood and the sides of the pallets, said upper sealing means comprising opposed slidably engaging sealing strips carried by the sides of the pallets and the sides of the hood respectively, there being longitudinally extending leaf springs sealably connecting the strips carried by one of these parts with the part and urging same into sealing engagement with the opposed strips.
