Definitions

  • the invention relates to a radiator grate plate with devices for attachment to a grate support and with openings for cooling gas opening on the upper side.
  • Stationary grate elements are known primarily for the thermally highly stressed part of a cooler (DE-PS 35 83 059), which consist of a number of support elements with approximately horizontally arranged air passage holes in the conveying direction. They are not suitable for fitting sliding grates with movable grate plates, and the unwanted rust diarrhea of fine particles cannot be completely avoided, especially when the cooling air is switched off.
  • the invention has for its object to provide a grate plate which has high thermal resistance and is therefore suitable for the thermally highly stressed area and can be connected to an air-guiding grate beam; which, however, can also be arranged in a movable manner in the pushing area and is functional within a grate which is open at the bottom, with grate diarrhea and clogging of the cooling air openings being made more difficult or impossible.
  • the solution according to the invention consists in that at least one trough for receiving and holding refrigerated goods is arranged on the top of the plate and the cooling air passage openings open within the area of the trough occupied by the refrigerated goods held.
  • the plate in this area is insulated from the hot clinker in relation to the hot clinker.
  • a number of troughs are expediently provided in order to be able to hold the refrigerated goods more securely therein.
  • the openings (or at least some of them) open into side surfaces of the trough, which in the operating state are arranged essentially vertically.
  • the through openings run in it at least in the area near the mouth, advantageously falling in the direction of flow, in order to prevent clinker from getting stuck in the openings and being able to penetrate into the air duct area.
  • the opening openings are expediently arranged in the side walls of the troughs, which run parallel to the direction of the relative movement, and are expediently slit-shaped.
  • the cooling gas is then fed to these openings through hollow ribs running in the conveying direction. Even if they do not enjoy the protection of an overlying clinker layer, they are well cooled by the cooling air flowing past.
  • the plate In those areas in which the plate is connected to an air-guiding grate carrier, it rests on an upper plate of the grate carrier that completely covers its air supply side. Due to the tight connection between the plate and this top plate of the grate carrier, individual sections of the cooling grate can be ventilated separately. It also ensures that all panels are evenly supplied with cooling air and thus in clinker bed zones avoid that the cooling air flows through the clinker bed via the path of least resistance and other areas and panels are cooled too little.
  • the cover on the underside of the plate through the top plate of the grate carrier constricts the flow cross sections leading to the openings located further forward. So that all openings are still flowed through evenly, it can be provided according to the invention that the openings further away from the lower-side cooling gas supply have a larger average cross-section than those closer to it.
  • the plates in the stationary area can simply be attached to the grate carrier top plate by screwing it conveniently attached for use in the grate area with a downward-open construction, as is known from DE-PS 24 32 599. All of the grate plates, which are arranged in the middle or end region of the cooling zone, partly movably, partly immovably above an air chamber, are then acted upon together with cooling air.
  • the troughs containing the cooling gas openings are expediently arranged only in the non-overlapped plate part.
  • top plates 2 are fixedly arranged on stationary supports 1, which are designed as air guide channels, on which Grate plates 3 are attached.
  • the upper plates 2 have recesses 4 encircling the edges of the grate plates for better connection and are screwed to the grate plates.
  • the grate plates 3 overlap in the area 5 and are provided with a seal 6 there. In the exposed area, they contain troughs 7, which are formed by transverse ribs 8 and longitudinal ribs 9. Cold refrigerated goods are held in them, which forms a protective cover against the hot refrigerated goods located above them.
  • cooling gas through openings 11 which run a little downward in the flow direction in order to make it more difficult for cooling air to pass into the interior of the plate to the gas supply area. They are slit-shaped in the longitudinal direction of the grate or in the direction of movement of the material. The part 12 of the ribs 9 located above the slots 11 protrudes further beyond the mouths of the slots 11 into the trough 7 than the part 13 located below, so that the mouth of the passage openings 11 is covered.
  • Air guide channels 14 are provided under the ribs 9. Furthermore, the trough floors 16 form a certain distance from the top plate 2 of the grate carrier, so that an air-guiding intermediate space 15 is formed between them. To compensate for the flow resistance in the air duct areas 14, 16, the slot 11 'in the foremost depression (far right in Fig. 1) is formed further than the slot 11 ⁇ in the middle depression and this in turn further than the slot 11 ′′′ in the rearmost Trough that is closest to the air-carrying grate support 1.
  • FIG. 1 shows an immovable grate plate arrangement
  • FIG. 2 illustrates a corresponding arrangement in a sliding grate.
  • movable grate supports 1 ' which are driven back and forth in the direction of the arrow in the longitudinal direction of the grate.
  • the front edge of the associated grate plate 3 takes the dash-dotted at 3 'and 3 ⁇ indicated extreme positions. So that, in no operating state, a trough of the plate shown on the right in the drawing gets under the left plate and blown chilled goods under the left plate can be, the troughs 7 are limited to that area that is always outside the overlap area. Otherwise, the grate plate arrangement of FIG. 2 is the same as that explained with reference to FIGS. 1 and 3.
  • grate plates of the type shown in FIG. 1 or 2 can also be used in the grate area in which the cooling gas is not supplied individually for each grate plate row by air-guiding grate supports 1.
  • the grate plates can then be fastened in a suitable manner without the grate support top plates 2.
