Definitions

  • the invention relates to a cooling grate of a grate cooler for hot goods, in accordance with the preamble of claim 1.
  • this invention is concerned with a cooling grate intended for a so-called moving grate cooler.
  • Grate coolers with a cooling grate of the type required in the preamble of claim 1 are known in various embodiments.
  • DE-AS 20 11 518 shows a cooling grate design in which the individual grate plates have vertically upwardly projecting ribs in their parts through which cooling air flows, which delimit box-shaped troughs, in the bottoms of which vertically running, conical bores for the passage of Have cooling air.
  • the individual grate plates are designed with troughs open to the upper side of the wings for receiving goods to be cooled, the cooling gas through openings also opening into the trough area here.
  • at least some radiator grate plates can be formed with hollow ribs running in the conveying direction for the cooling gas guidance, wherein the cooling gas passage openings can be provided in these longitudinal hollow ribs.
  • the invention is therefore based on the object of providing a cooling grate of the type required in the preamble of claim 1, in which the requirements explained above (in particular in the area of the grate plates) can be met together in a particularly advantageous manner.
  • At least one pocket-shaped recess is worked into the supporting surface of each grate plate from above, which has at least one window-like through hole (ie a correspondingly large, free through opening) at its bottom and in which a strip-shaped ventilation cover cap is fitted and arranged in this way that a cooling air passage opening is in the form of an essentially closed annular gap.
  • a cooling gas duct within each grate plate through which practically all areas of the wing sections coming into contact with hot material (eg hot cement clinker coming from a furnace) can be optimally cooled by a correspondingly high air speed in the annular gap.
  • the cooling gas emerging from these annular gap-shaped through openings also sweeps over the side surfaces of the annular gap regions and thus provides additional heat dissipation at the lower region of the grate plates.
  • the cooling gas resistance can be predetermined by the gap width of the cooling gas passage openings in the manner required. It can above all be ensured that the cooling gas itself is supplied at a sufficiently high speed for cooling the grate plates or their wings, whereas the cooling gas speed in the area in which the cooling gas enters the material to be cooled, can be reduced so significantly that an optimal gas distribution in the material and thus a particularly intensive cooling of the hot material is made possible.
  • each grate plate which is formed in each case from the plate base or main body and at least one correspondingly designed and arranged ventilation cover cap
  • the multi-part design of each grate plate also proves to be particularly advantageous from a production point of view if these plate parts are manufactured as castings. If one compares this with the known embodiment according to DE-OS 38 12 425 explained above, one will find that it is extremely difficult with the grate plate, which is obviously made in one piece, defined passage cross-sections for the cooling gas through openings in a casting process.
  • this cooling grate belongs to a grate cooler, in particular a moving grate cooler, which is used for cooling hot goods, such as hot cement clinker coming from an upstream furnace is determined, the material to be cooled being longitudinal, i.e. is transported in the direction of arrow 1 over the cooling grate.
  • This cooling grate contains, in a manner known per se, a multiplicity of rows of grate plates 2 which adjoin one another in the longitudinal direction and overlap.
  • the grate plates of each row lying next to one another in the transverse direction of the grate are each fastened to a grate plate support 3 which runs transversely to the grate, in FIG. 1 only one of these grate plate supports 3 is illustrated.
  • This grate plate carrier 3 is designed as a hollow body and for the supply of cooling gas (arrows 4) from below and with a cooling gas chamber or source not shown in detail connected, cooling air - as known per se - can be used as cooling gas.
  • Each grate plate 2 has an airfoil 5, via which the goods to be cooled are transported along.
  • each pocket-shaped recess 6 is worked into the supporting surface 5 of each grate plate 2, which is at least one relative to its base 7 has large, free, window-like through hole 8.
  • two pocket-shaped depressions 6 are preferably provided in the grate plate 2 or its supporting surface 5.
  • a strip-shaped ventilation cap 9 is also fitted and arranged in each recess 6 in such a way that cooling gas through-openings 10 opening out towards the top of the wings 5 are in the form of essentially closed annular gaps, i.e. these annular gap-shaped cooling gas through-openings 10 are delimited on the one hand by the approximately upright inner sides 6a of the pocket-shaped recesses 6 and on the other hand by the outer peripheral edge 9a of the ventilation cover caps 9.
  • each ventilation cap 9 It is also important that between the bottom-side edge area 9b of each ventilation cap 9 and the edge area 7a of the recess bottom 7 opposite this edge area is formed an essentially annular cooling gas inlet slot 11, the clear width of which is distributed accordingly by the arrangement of several arranged Distance elements 12 can be determined.
  • These spacer elements 12 are preferably attached in one piece in a corresponding distribution to the underside of each ventilation cap 9, as indicated in FIG.
  • each wing recess 6 on its central section covered by the associated ventilation cap 9 opposite its remaining peripheral edge surface that is to say the one under the associated annular-gap-shaped cooling gas Passage opening 10 lying edge area is increased.
  • the peripheral edge region 7a of the base 7 already mentioned above is formed, preferably in such a way that - viewed in the cross section of the grate plate 2 - it slopes obliquely outwards and downwards in the direction of the lower section of the associated annular-gap-shaped cooling gas Passage opening 10 has.
  • the lower or lower edge region 9b of the associated ventilation cover cap 9 is also inclined obliquely outwards and downwards over the entire circumference.
  • the cooling gas passage slot 11 formed between these two circumferential edge regions 7a and 9b, which are at a distance from one another and viewed in vertical section through the grate plate 2 is also inclined downward in the cooling gas entry direction (arrows 4 in FIG. 1), specifically in FIG the way that it opens over its entire circumference in the lower section of the associated annular-gap-shaped cooling gas passage opening 10 (see FIGS. 1 and 2).
  • This design and arrangement of the cooling gas inlet slots 11 (in cooperation with the cooling gas through openings 10 and a corresponding cooling gas velocity) can be reliably prevented that no fine portions of the good to be cooled can fall down through the grate plate 2 or its cooling gas passage openings 10.
  • each ventilation cap 9 has transverse webs 13 having a plurality of bores 14.
  • These holes 14 are intended for receiving fastening bolts 15, which each ventilation cap 9 has on its underside.
  • These downwardly projecting fastening bolts 15 are inserted into the holes 14 in the supporting webs 13 of the raised base section to such an extent that they are fixed, preferably welded, in the appropriate height position of the cover cap 9. This height of the cover cap relative to the raised portion of the recess bottom 7 lying underneath thus also determines the clear width of the annular cooling gas inlet slot 11, as can be seen easily in FIGS. 1 and 2.
  • the ventilation cover caps 9 all have a substantially flat upper side.
  • the arrangement of the raised central portion of the floor 7 and the ventilation cap 9 is such that the top 9c of the cap 9 is opposite the top, upper plane 5a of the wing 5 is lowered by the dimension A (Fig.2).
  • a ventilation pocket 16 is also formed in the area above the ventilation cover cap 9, which can fill with material during the cooling operation of the cooling grate or grate cooler and can thereby particularly advantageously protect this area of the grate plate 2 or airfoil 5 against wear.
  • a further advantage of these ventilation pockets 16 during cooling operation is that the cooling gas emerging from the annular gaps 19 in these ventilation pockets above the cover caps 9 form a kind of fluidized bed of the goods stored therein, which then enters a relatively large area into the refrigerated goods bed above it and thus one optimal cooling of the goods favors.
  • the cooling gas through openings 10 delimited by the depressions 6 and the ventilation cover caps 9 could have any suitable elongated annular gap shape running in the direction of the goods to be conveyed (arrow 10), insofar as this allows the largest possible cooling gas passage or outlet from the grate plate 2 in the refrigerated goods bed is guaranteed.
  • the depressions 6 and the ventilation cover caps 9 inserted therein have an elongated rectangular shape in such a way that the annular gaps forming the cooling gas passage openings 10 have a top view have an elongated rectangular shape closed on the wing 5 (see FIG. 3), the long sides of the rectangle running essentially parallel to the conveying direction (arrow 1) of the goods to be cooled.
  • the depressions 6 with their ventilation cover caps 9 can only be arranged in the larger longitudinal section of the grate plate 2, which is in the front in the direction of material conveyance (arrow 1) the reciprocating pushing movement of the rows of grate plates is not brushed by the grate plates 2 lying above them (cf. illustration in FIG. 1).
  • FIGS. 6 and 7 A second exemplary embodiment for the formation of grate plates for the cooling grate according to the invention will first be described with reference to FIGS. 6 and 7.
  • the grate plate 2 'or its wing 5, on its front longitudinal section pointing in the direction of material conveyance (arrow 1) has two evenly distributed cooling gas or cooling air passage openings 10' which face towards the top of the Wing 5, open out and are again in the form of substantially closed annular gaps.
  • two such cooling gas passage openings 10 'in the form of an annular gap are appropriately evenly distributed with an adapted size and elongated rectangular shape and are adapted to the area size.
  • annular gap-shaped cooling gas through openings 10 ' are also formed by incorporating two pocket-shaped recesses 6' from above into the support surface 5 'of the grate plate 2', which have a plurality of through holes 8 'on their base 7' and in each of them a strip-shaped ventilation cap 9 'are fitted and arranged to form the said annular gap.
  • each ventilation cap 9 ' has a flat upper side which is flush with the upper side of the wing 5' (see FIG. 7).
  • FIGS. 6 and 7 show an embodiment according to which the flow direction (arrow 1) of the longitudinal sections of the rectangular, annular-gap-shaped cooling gas passage openings 10 ', which are to be cooled, run inclined to the vertical, ie all longitudinal sections of the annular-gap-shaped cooling gas through openings 10 'of a grate plate 2' are inclined in one direction at approximately the same angle to the vertical (cf. cross section in FIG. 7).
  • FIG. 8 also shows a partial cross-sectional view of a grate plate carrier 3 ′, again designed as a hollow body, which is designed for the supply of cooling gas from below and on its top side a series of grate plates placed next to one another in the transverse direction - for example in the embodiment according to FIGS 7 - carries.
  • the grate plates 2 '(or 2) can be designed and attached to the grate plate supports 3' (or 3) in such a way that at least the bottom 7 '(or 7) of the Recesses 6 '(or 6) and the ventilation cap 9' (or 9) arranged above them can be flowed freely from below by the cooling gas (dashed arrows 4).
  • grate plates 2 'of the embodiment described with reference to FIGS. 6 and 7 are fastened to the grate plate carrier 3' there, then it is preferred to arrange these grate plates 2 'in such a way that - in cross section of the cooling grate viewed and in each case starting from the vertical longitudinal center plane 17 - the longitudinal sections of the cooling gas passage openings 10 'located on the two transverse halves of this cooling grate are each inclined toward the closest outer longitudinal side of the cooling grate.
  • the cooling gas emerging from the cooling gas passage openings 10 'upwards can to a large extent in the transverse direction to the material conveying direction (arrow 1 in FIG. 3 or perpendicular to the plane of the drawing in FIG. 8) enter the goods to be cooled.
  • a kind of tripartite division of the cooling gas guidance can be brought about, namely on the one hand a relatively high gas speed (for example about 40 m / s) in the area of the cooling gas inlet slots 11, on the other hand a gas speed correspondingly reduced by the larger opening cross-section (approximately in the range of 12 to 15 m / s) in the area of the annular gap-shaped cooling gas passage openings 10 and thirdly by one in the area of the Ventilation pockets 16 very greatly reduced gas speed, which is only a few m / s (possibly only slightly greater than 0).
  • This three-stage cooling gas guide ensures that the wing sections coming into contact with hot material are each Grate plate 2 are adequately cooled, prevents fine parts from entering the cooling gas inlet slots and optimal distribution of the cooling gas escaping upwards in the goods to be cooled (bed) and thus an optimal, very intensive cooling effect is achieved.
  • FIG. 9 shows an embodiment variant in which the individual grate plates 22 largely correspond in their structural design to the construction of the exemplary embodiment explained with reference to FIGS. 1 to 5, so that all similar grate plate parts are also provided with the same reference numerals.
  • the special feature of this embodiment variant can be seen in the fact that each of these grate plates 22 is essentially flat and has no special ventilation pocket (see. Ventilation pocket 16 in FIG. 2), ie in these grate plates 22 each essentially flat upper side of the ventilation cover cap 9 is located flush with the top of the wing 5 (About the same as described with reference to Fig. 7 of the second embodiment).
  • FIGS. 10, 11 and 12 also starts from the basic construction of the first exemplary embodiment described with reference to FIGS. 1 to 5, so that here again the same grate plate parts are provided with the same reference symbols. It can be seen in particular from FIGS. 11 and 12 that here, too, two equally sized pocket-shaped depressions 6 are formed in the supporting surface of each of the grate plates 32 shown here, into each of which a strip-shaped ventilation cover cap 9 is fitted and arranged on the bottom 7 is that there is a cooling gas passage opening 10 in the form of a closed annular gap.
  • each ventilation cap 9 is additionally lowered by a suitable dimension A with respect to the upper side 5a of the wing 5 with the additional formation of a ventilation pocket 16 (similar to the first exemplary embodiment in FIGS. 1 to 5).
  • each depression 6 is primarily composed of two longitudinal webs, spaced apart from one another and parallel to one another and to the material conveying direction (arrow 1), namely the webs 33, 34 on the one hand and the webs 34 and 35 on the other hand, as well as a front end web 36, viewed in the direction of good conveyance (arrow 1), which runs across the entire grate plate 32.
  • the material conveying direction arrow 1
  • FIGS. 10 to 12 This embodiment variant of FIGS.
  • the 10 to 12 differs primarily in that, in addition to the end web 36, only the two outer longitudinal webs 33 and 35 extend to the height of the wing top 5a while forming an approximately box-shaped common ventilation pocket 16 the upper edge 34a of the central longitudinal web 34 lies approximately at the level of the upper sides 9c of the two ventilation cover caps 9.
  • the height of the central longitudinal web 34 is reduced compared to the other longitudinal webs 35, 36.
  • the embodiment variant of grate plates 42 illustrated with reference to FIGS. 13 and 14 also deals with the formation of the ventilation pockets 16 in the area above the ventilation cover caps 9.
  • only the front end web 36 extends to form the ventilation pocket 16 up to the height of the wing top 5a.
  • all of the longitudinal webs 33, 34 and 35 running in the material conveying direction (arrow 1) are only guided up to the height of the upper sides 9c of the ventilation cover caps 9, ie their upper edges lie approximately in the same plane as the upper sides of these ventilation cover caps 9.
  • the ventilation pocket In this embodiment variant 16 is therefore mainly limited by the front end web 36 and of course also by the rear part (see wing 5) of these grate plates 42, as viewed in the direction of good conveyance (arrow 1), as can be seen from FIG. 13 .
