Definitions

  • the invention relates to a cooling grate for a bulk material cooler, in particular for combustible material such as cement clinker, the upper side forms a cooling surface supporting the cooling, wherein the cooling grate is composed of a plurality of fixed partially overlapping shape profiles, between which gas passageways are formed.
  • Cooling grates of this type are used for receiving and cooling of the cooler supplied Brenngut.
  • the cooling grate has to fulfill essentially three functions, namely to carry the kiln to be cooled, to provide feeds for the cooling gas and to form a basis for a delivery system for the kiln to be cooled.
  • the conveyor system ensures that the fuel is transported via the fixed cooling grate.
  • Such a cooler is from the EP-B-0 676 031 known.
  • the first type is designed as a cross-sectionally substantially rectangular beam whose underside has a central recess extending in the longitudinal direction.
  • the second type of shaped profiles has the shape of an inverted T in cross-section, wherein the transverse parts of the T are provided at their free ends in each case with an extending in the direction of the longitudinal part of the T edge.
  • the two types of shaped profiles are arranged alternately. In this case, the edges engage in the recess of one of the rectangular shaped profiles on the transverse parts of the two directly adjacent T-shaped shaped profiles. This creates between each a rectangular shape profile and a T-like shape profile, a gas passageway.
  • the channel is not straight, but has several deflections to prevent material breakdown.
  • a disadvantage of the known cooling grate that the shape of profiles with their depressions or their edges to produce consuming and also are quite difficult to assemble. In addition, two different types of shape profiles are required, which further increases the required effort.
  • a genre foreign cooling grid is in the DE-A-195 37 904 described. It is formed from several shape profiles, which are joined together closely with their long sides.
  • the shape profiles have groove-like recesses on their longitudinal sides which are intended to rest on adjacent shaped profiles, which run obliquely from the underside to the upper side. In the assembled state, these groove-like recesses form gas passageways from the bottom of the cooling grate to the top thereof.
  • the disadvantage of this is that the mold profiles are expensive to manufacture with their recesses. This is all the more so because a separate recess is required for each gas passageway. For a good, uniform cooling result, a plurality of gas passageways are required, whereby a considerable effort is required.
  • cooling grates are expensive to manufacture and assembly.
  • a movable sliding grate is used instead of the fixed cooling grate.
  • the sliding grate consists of several rows, which are arranged alternately fixed and movable.
  • the movable rows are reciprocated. This reciprocating movement transports the cooling material along the sliding grate.
  • the rows of the push grate are often made up of several plate elements ( WO 99/44001 . US 5,174,747 ). Because of the movable rows, push grates are expensive to manufacture and operate.
  • the solution according to the invention lies in a cement clinker cooler grate with the features of claim 1.
  • Angled in opposite directions is understood here to mean that, relative to the middle part, one of the outer parts is angled toward one side of the middle part, while another outer part is angled toward the opposite side of the middle part.
  • the outer parts thus have in opposite directions, and it is not necessary that they have in exactly opposite directions, ie offset by 180 ° to each other.
  • the invention has recognized that with the inventive design of the mold profiles of the considerable effort, which is due to the use of two different shape mold profiles, can be avoided.
  • the cooling grid according to the invention is therefore easier to manufacture and also cheaper to maintain.
  • it is easy to assemble, because the shaped profiles overlap roof-like and can be easily positioned one after the other.
  • the opposing resistance of the gas stream decreases considerably, whereby either the amount of the cooling gas flow can be increased or the supply device for the cooling gas can be dimensioned smaller. Fewer deflections in the gas passage channel also mean less turbulence, whereby the uniformity of the cooling gas admission of the combustible material to be cooled is increased.
  • the outer parts are arranged in the region of the gas passageway parallel to each other. This has the advantage that the gas passage channel between the two parallel outer parts has a constant width. Narrows with their disadvantages in terms of resistance increase and vortex formation are thus avoided. This results in a better and more uniform distribution of the cooling gas.
  • the outer parts are arranged so that the gas passage channel formed by them exiting refrigerant gas directs a direction component parallel to the plane of the cooling grate.
  • a more uniform cooling can be achieved, since in this way more cooling gas passes into the areas of the combustible material between the gas passageways.
  • the shape profile is formed with rounded angles.
  • a rounded design of the angle between the central part and the outer parts has the advantage that the cooling gas when entering the gas passage channel can more harmoniously pass through the transition region between the middle part and the outer part. This also avoids the formation of vortices and favors a uniform guidance and thus distribution of the cooling gas.
  • the mold profile is Z-shaped.
  • Such a design of the molded profile has the advantage of particularly simple production and assembly of the molded sections to a cooling grid.
  • the gas passage channel formed between two outer parts of mutually adjacent mold profiles is also aerodynamic in a Z-shaped design of the mold profiles, since apart from the inlet and outlet within the gas passage channel no deflection of the gas flow takes place, but the cooling gas can flow straight.
  • Z-shaped here is not only the case understood that the outer parts are arranged at an acute angle to the middle part, but they can be arranged with advantage also at right angles or even obtuse.
  • the middle part and / or the outer parts are flat, but this is not essential. They can also be curved. The latter even has the advantage that the transitions between the central part and the outer part can be made more harmonic, whereby the gas passage channel presents less resistance to the cooling gas flow.
  • the shape profiles are point-symmetrical. This results in the advantage that the assembly of the mold sections to form the cooling grate is further simplified because it makes no difference whether they are installed rotated by 180 ° or not. Mixing up during assembly is practically impossible.
  • the shape profiles are arranged transversely with respect to the conveying direction of the combustible material to be cooled.
  • a favorable arrangement of Gasdruchtrittskanäle achieved, on the other hand, and above all, however, a greater braking effect is exerted on the kiln.
  • a support which has position-determining receptacles for the shaped profiles.
  • the shots allow a simple and positionally accurate mounting of the mold profiles on the carriers. This is especially true when angular position and longitudinal position are determined by the recordings.
  • exemplary embodiments are assumed to be a cooling grate for a cooler, through which cooling gas flows from bottom to top, thereby serving to cool hot material, in particular hot cement clinker or the like.
  • FIG. 1 A first embodiment of the cooling grid according to the invention will be explained with reference to FIG. 1.
  • a cooling grate 1 is provided, rests on the kiln 8 to be cooled and is transported by a conveying mechanism (not shown) in a conveying direction 9.
  • a plenum 6 is formed, which is supplied by a cooling gas supply device (not shown) cooling gas to finally be fed through the cooling grate 1 through the kiln 8 for cooling.
  • the cooling grate 1 is arranged on two transversely to the conveying direction 9 extending, I-shaped main beams 2. For the sake of simplicity, only two of these main beams 2 are shown, however, any number of main beams 2 may be provided.
  • longitudinal beams 3 Transverse to the main beams 2 and thus parallel to the conveying direction 9 longitudinal beams 3 are arranged. They have at their ends recesses 31 for resting on the main beams 2.
  • the upper side 32 of the longitudinal members 3 is provided with a sawtooth-like serration 36.
  • the serration 36 is designed so that when connecting a neighboring longitudinal member 3 at this end, the serration 36 passes continuously. Depending on a recess of the serration 36 forms a receptacle for one of the mold profiles. 4
  • the shape profile 4 is Z-shaped. It has a plate-like central part 41, at the opposite ends in each case an outer part 42, 43 is arranged.
  • the outer parts 42, 43 are arranged at right angles and in opposite directions facing the central part 41.
  • the outer part 42 located in the conveying direction 9 at the rear points obliquely upwards, while the outer part 43 located in the conveying direction 9 points obliquely downwards.
  • a transition region between the middle part 41 and the outer parts 42, 43 is rounded at the inwardly facing side 44 and executed on the opposite, outwardly facing side 46 square.

  • Apart from the region of its inlet 51 and its mouth 52 of the gas passageway 5 runs between the parallel outer surfaces 42 ', 43rd just.
  • the position of the mold profiles 4, 4 'to each other is determined by the Zakkung 36 of the main carrier 3.
  • the gas passageways 5 are defined in terms of their design by the design of the serration 36 and the mold sections 4.
  • the width of the gas passageway 5 is determined by the distance of the serration 36 on the one hand and by the shape and thickness of the material of the outer parts 42 ', 43 on the other. Adjustments are not required. It is sufficient for mounting the cooling grate 1 so completely that after assembly of the support structure 2, 3, the mold sections 4 are successively inserted into the serration 36 of the longitudinal member 3 and secured there. This creates both the support surface for the kiln 8 to be cooled as well as the gas passageways 5.
  • the cooling grate 1 allows a high degree of prefabrication, so that then only the individual parts need to be assembled on the site.
  • the result is a cooling grate, on the one hand has advantages in terms of a simple structure as well as on the other hand, the quality of the cooling gas flow.

  • the relative position of the parts, in particular the shaped sections 4 is already determined by the design of the longitudinal members 3 and unchangeable. Assembly errors are largely excluded. If the mold sections 4 are used successively opposite to the conveying direction 9, then the insertion of the individual shaped sections 4 into the serration 36 is particularly easy, without the need for special and difficult-to-use threading operations.
  • cooling gas passageways 5 passed cooling gas obliquely with respect to the conveying direction, d. H. with a horizontal component parallel to the plane of the cooling grate 1, from the cooling grid 1 and into the kiln 8 to be cooled.
  • the oblique guidance of the cooling gas combines advantages in terms of better and above all uniform cooling effect and reduction of material diarrhea in or through the gas passageways 5.
  • the material diarrhea inhibiting deflections are therefore required only to a lesser extent, which not only improves the gas flow, but also the risk is reduced by blockages.
  • the arrangement of the mold profiles 4 transverse to the conveying direction 9 has the advantage that the cooling grate 1 has a braking effect on the kiln 8. Such a braking effect may be desirable to allow sufficient residence time of the combustible in the cooler guarantee.
  • the braking effect is advantageously increased by the fact that the outer angle 46, which protrude into the bed of the combustible material 8, have a polygonal edge and not, as the inner angle 44, are rounded.

  • the width of the gas passageway can be changed according to the distance between two adjacent mold sections 14, 14 '.
  • variations can be made in order to guide a larger or smaller volume flow of cooling gas to the kiln to be cooled at certain points through a further or a narrower gas passage.
  • it may be advisable to set the shape profiles 14 at a smaller distance from one another in areas with a high cooling power requirement, in order thus to achieve a greater width of the gas passageways 15.
  • Such variations are not limited to taking into account differences in the cooling power requirement, but may advantageously be used to compensate for differences in the supply of cooling gas.
