Definitions

  • the invention relates to a device for cooling bulk material comprising a grate conveying a layer of the bulk material along a conveying direction with a device for supplying cooling gas, wherein the grate comprises conveying elements and forms a substantially planar support surface for the layer of bulk material.
  • Devices of the type mentioned serve as a grate cooler in particular for cooling burned Good, for example for emerging from an upstream furnace cement clinker.
  • the bulk material dropped from the upstream workstation usually the furnace, is transported along the cooling grid to the downstream workstation and thereby cooled.
  • the grate cooler In order to cool the bulk material located on the grate, the grate cooler has a feed for cooling gas. This is usually done by blowing cooling gas through the grate so that it enters from below into the bulk material to be cooled, flows through it and leaves upwards. Difficulties often arise in the supply of cooling gas from the fact that for effecting the promotion of the bulk material along the cooling grate parts of the grate are designed to be movable.
  • the invention is based on the object to provide, starting from the above-mentioned prior art, an improved cooling grate which avoids the disadvantages mentioned.
  • a device for cooling bulk material which has a grate conveying a layer of the bulk material along a conveying direction with a device for supplying cooling gas, wherein the grate comprises conveying elements and forms a substantially flat support surface for the layer of bulk material
  • the support surface is at least partially provided with a flat blower, which is a tissue as a spatially extended dispersion element, on which the bulk material rests directly, and having a supporting structure arranged underneath.
  • the invention is based on the idea of creating a composite by means of the dispersion element and the support structure arranged directly underneath, which on the one hand provides a large outlet area for the cooling gas, and on the other hand is sufficiently robust for supporting the overlying layer of the bulk material to be cooled.
  • the fabric provides a plurality of small passageways for the cooling gas. Depending on whether a more or less fine dispersion is to be achieved, the fabric may consist of nonwoven material or of metallic material (wire mesh).
  • the support structure Due to its structure, on the one hand, it provides a large area for the passage of cooling gas and, on the other hand, prevents rust throughput, ie the falling through of bulk material to be cooled into the space below the grate, due to the smallness of the channels (or mesh or pores) conducting the cooling gas. Small means a width of the channels, which is considerably smaller than particles of the bulk material.
  • the support structure ensures that the tissue, which is not sufficiently stable in itself, is given sufficient mechanical strength and load-bearing capacity.
  • a cooling grate is known in which the support surface is formed as a perforated plate, on which rests on a layer of the bulk material to be cooled and on the underside of a fabric material is arranged.
  • the fabric material can act as a dispersion element for supplied from below cooling gas.
  • the perforated plate arranged above the fabric material protects the fabric material from wear.
  • a particular advantage of the arrangement of the support structure directly under the fabric as a dispersion element is that a reliable mechanical support is achieved. Ausackungen or depressions under the load of the weight of the overlying layer of the bulk material to be cooled no longer occur thanks to the invention. The burden on the dispersion element can thus be reduced thanks to the invention. This not only allows the use of thinner material, such as the inherently delicate fabric material, for the dispersive element, but also reduces the susceptibility of the construction to damage.
  • a trough is provided, in which the support structure and on the edge of the dispersion element are arranged, wherein the trough on the bottom side a supply port for the cooling gas.
  • a separate unit is created, which can be manufactured separately from the grid and mounted.
  • the composite of dispersion element and support structure is designed as an exchangeable module. This makes it possible to provide standardized modules, which only need to be used on appropriately prepared receiving points of the grate. Production and assembly are thus considerably easier. It is also possible with the execution as a module, if necessary, easily make an exchange.
  • a matrix arrangement In an embodiment as a module, it is expedient to provide a matrix arrangement.
  • it has proven useful in cooling grids according to the "walking floor" principle with several parallel side by side longitudinally displaceable in the conveying direction and alternately back and forth moving planks several modules in the conveying direction to be arranged one behind the other.
  • webs projecting into the bulk material are arranged transversely to the conveying direction.
  • an area is formed in which the bulk material resting directly on the dispersion element does not or hardly moves, up to a certain layer thickness influenced by the web height.
  • This part of the bulk material layer is thus virtually calm with respect to the dispersion element. It thus forms another protection, which automatically develops during operation, from wear by the bulk material to be cooled.
  • the dispersion element is so by the bottom layer of the bulk material to be cooled, which is due to the arranged transversely to the conveying direction webs quasi-stationary to the respective element of the grate, from wear by the rest, due to their abrasive Components often spares bulk wear-aggressive bulk.
  • a material sump is expediently provided parallel to the conveying direction of the side of the dispersion element in the support grid. It serves to provide a collecting space downwards from the layer of the bulk material to be conveyed, which migrates away from the bulk material, in particular fine dust constituents. It has been found that otherwise the downwardly migrating fines could clog the dispersing element.
  • the material sump it is achieved that this material accumulates in the space created by the material sump.
  • the dispersion element can be protected from clogging, and any remaining small amounts of fine constituents that may still be present on it can be discharged thanks to the cooling gas flow passed through the dispersion element.
  • the material sump may have any desired shape in cross-section, in particular it may be square, rectangular or even round.
  • the dispersion element is formed across several adjacent modules.
  • overlapping is understood here to mean that a uniform piece of the dispersion element spans the area of a plurality of support structures which adjoin one another, in particular in the conveying direction.
  • the support structures can in this case be arranged at a certain distance from each other, but it is more expedient to arrange them directly adjacent to one another. this makes possible a maximum extent of the area used for blowing out cooling gas.
  • the support structure is preferably formed by a plurality of cross member arranged plate elements.
  • the plate elements may be provided with slot-like recesses corresponding to the width of the support grid to allow mating of the plate elements to the support structure.
  • the plate elements are designed so that they are the same shape. It can be further provided that they are equal in length, but this is not absolutely necessary.
  • the inventive composite of dispersion element and support structure can be arranged in a fixed part or a movable part of the cooling grid. It can also be provided a combined arrangement.
  • a particular advantage of the construction according to the invention lies in the fact that it is due to their simplicity and in particular their modular design to an arrangement in a movable element of cooling grates suitable.
  • the dispersion surface can be arranged so that it is positioned between the remaining space for conveying elements for the layer of the bulk material to be cooled.
  • the use of the cooling grid according to the invention is also possible in such Brenngutkühlern having separate (and not as in the "walking-Floor" principle in the actual grate integrated) conveying elements.
  • the dispersion element is such that its grid width is less than 1 mm.
  • grid width hereby means the width of a channel leading through the dispersion element for the supply of cooling gas. With this width, sufficient safety can be achieved with respect to an undesirable entry of bulk material, without resulting in an unnecessarily high pressure loss with respect to penetrating or falling bulk material.
  • a schematic embodiment of cooler according to the invention is in Fig. 1 shown.
  • a housing 1 has at one end to a feed chute 12, in which a discharge end of a rotary kiln 2 opens.
  • refrigerated goods falls in the feed chute 12 on a task section 14 of the radiator and passes from there to an inventively designed grate 3.

  • the grate 3 is formed from a plurality of planks 31 arranged parallel in the conveying direction 60.
  • the planks are individually movable back and forth and are driven by a motion controller so that they are advanced together and moved back individually.
  • This conveying principle for cooling grates is known as "walking floor" ( DE-A-19651741 ); to the explanation of details on structure and operation can therefore be omitted.

  • the support grid 42 is formed from a plurality of plate-like segments 43, which are joined together in a cross-compound.
  • the upper edges of the segments 43 are in one plane and form a support for the metal fabric 41. This ensures that the metal fabric 41 is not deformed or damaged even under the weight of a resting layer of goods to be cooled.
  • the cooling gas supplied via the connecting piece 40 is distributed between the segments 43 of the support grid 42, so that it is supplied to the metal fabric 41 from below. It flows through the metal fabric 41, wherein it is finely distributed and large area of the metal fabric 41 enters the overlying layer of material. This results in both a large-scale and uniform transfer of the cooling gas into the refrigerated goods.
