Definitions
- the invention relates to a cooling grate for a bulk material cooler, especially for fired goods such as cement clinker, whose Top forms an airfoil supporting wing, wherein the cooling grate is made up of a plurality of fixed ones partially overlapping shape profiles is composed, between which gas passage channels are formed.
- Cooling grates of this type are used to hold and cool the firing material supplied to the cooler.
- the cooling grate in the perform three essential functions, namely that to be cooled To carry the firing material, to provide feeds for the cooling gas as well as a basis for a conveyor system for the to be cooled Form firing material.
- the conveyor system takes care of you Transport of the firing material over the fixed cooling grate.
- Such a cooler is known from EP-B-0 676 031.
- Two different ones are used Types of shape profiles.
- the first type is as a cross section designed essentially rectangular bar, the Underside has a central recess, which is in Extends in the longitudinal direction.
- the second type of shaped profile has the shape of an inverted T in cross section, wherein the transverse parts of the T at their free ends each with a edge extending in the direction of the longitudinal part of the T. are.
- the two types of shape profiles are alternating arranged.
- One of the rectangular shaped profiles the edges on the cross parts of the two immediately adjacent T-shaped profiles. This creates a rectangular shape between each and a T-shaped shape profile a gas passage.
- the channel is not straight, but points to the prevention from material diarrhea to several diversions.
- Disadvantageous the well-known cooling grate is that the shaped profiles with their Wells and their edges to produce and are also quite difficult to assemble.
- a non-generic cooling grate is described in DE-A-195 37 904. It is made up of several shaped profiles, which with their long sides are joined closely together. The shaped profiles point to their adjacent ones Shape profiles certain longitudinal sides of groove-like recesses that run obliquely from the bottom to the top. in the When assembled, these groove-like recesses form Gas passage channels from the bottom of the cooling grate too the top of it.
- the disadvantage of this is that the shaped profiles with their recesses complex to manufacture are. This is all the more true because it applies to everyone Gas passage duct a separate recess is required. For a good, even cooling result, there are a variety of gas passage channels required, creating a considerable Effort is required.
- Cooling grates are complex to manufacture and assemble.
- cooler in addition to the cooler type described above, there is another known another type of cooler, in which the one to be cooled Grate carrying the firing material and the conveyor system for transporting the Fired goods are not formed separately from one another via the cooler are.
- a movable sliding grate is used instead of the fixed cooling grate.
- the moving grate is there from several rows, which alternately fixed and movable are arranged.
- the cooling firing material moves back and forth along the Moving grate.
- the rows of the sliding grate are common made up of several plate elements (WO 99/44001, US 5,174,747). Because of the moving rows, sliding grates are expensive in the manufacture and operation.
- the solution according to the invention lies in a cooling grate with the Features of claim 1. Accordingly, for a cooling grate for a cooler for fired goods such as cement clinker, the top of which forms an airfoil supporting the fuel to be cooled, wherein the cooling grate is made up of a plurality of fixed ones partially overlapping shape profiles is composed, between which gas passage channels are formed, that the shape profiles are the same shape and a middle part and also have outer parts that are opposite to the central part are angled, the shaped profiles being arranged so that one of the gas passage channels between each of the Outer parts of two immediately adjacent shaped profiles are formed is.
- Angled in opposite directions is understood to mean that related to the middle part of one of the outer parts to one side the middle part is angled, while another Outer part to the opposite side of the middle part is angled.
- the outer parts therefore face in opposite directions Directions, it is not necessary that they in exactly opposite directions, i.e. offset by 180 ° point to each other.
- the invention has recognized that with the design according to the invention the form profiles the considerable effort that is required by the use of two different shape profiles is, can be avoided.
- the cooling grate according to the invention is therefore easier to manufacture and also cheaper in maintenance. It is also easy to assemble because the Form profiles overlap like a roof tile and so easy can be positioned one after the other. These advantages will be not bought with a deteriorated cooling result, but the cooling grate according to the invention even has one cheaper design of the gas passage channels.
- the outer parts are expediently in the region of the gas passage channel arranged parallel to each other. That has the Advantage that the gas passage between the two parallel arranged outer parts has a constant width. Constrictions with their disadvantages in terms of increasing resistance and vortex formation are avoided. This results a better and more even distribution of the cooling gas.
- the outer parts are arranged so that the cooling gas emerging from them formed a gas passage Directional component parallel to the level of the cooling grate.
- Cooling gas flow can achieve more uniform cooling, because this way more cooling gas in the areas of the fuel between the gas passage channels. Furthermore with such an arrangement, the risk that Fired material penetrates into the gas passage channels and falls through.
- a rounded version of the angles between the middle part and the outer parts has the advantage that the cooling gas when entering the gas passage the transition area between the middle part and can happen to the outer part. This also avoids education of whirls and favors even leadership and thus Distribution of the cooling gas.
- the shaped profile is expediently Z-shaped.
- Such a design of the shaped profile has the particular advantage simple production and assembly of the shaped profiles to a cooling grate.
- the one between two outer parts is adjacent gas profiles formed gas passage with a Z-shaped design of the shaped profiles also aerodynamically, since apart from the entry and exit area inside of the gas passage channel no deflection of the gas flow takes place, but the cooling gas can flow straight ahead.
- Z-shaped here means not only the case that the outer parts at an acute angle to the central part are arranged, but they can also be advantageous be arranged at right angles or even obtuse angles.
- middle part and / or the outer parts are flat, but this is not essential required. They can also be curved his. The latter even has the advantage that the transitions between Middle part and outer part can be made more harmonious, whereby the gas passage channel has less resistance to the cooling gas flow opposes.
- the shape profiles point symmetry. This has the advantage that assembly of the shaped profiles to form the cooling grate is simplified because it makes no difference whether it is around Installed rotated 180 ° or not. Confusion at assembly is practically impossible.
- the shaped profiles are expediently transverse, based on the Conveying direction of the kiln to be cooled, arranged.
- a favorable arrangement of the gas passage channels achieved on the other hand and above all, becomes a larger one Braking effect on the firing material.
- a carrier which has position-determining receptacles for the shaped profiles.
- the recordings allow a simple and precise position Assembly of the shaped profiles on the beams. This is especially true then when through the recordings angular position and Longitudinal position are determined.
- FIG. 1 A first embodiment of the cooling grate according to the invention will be explained with reference to FIG. 1.
- a cooling grate 1 Inside a cooler a cooling grate 1 is provided on which to be cooled Firing material 8 rests and from a conveyor mechanism (not shown) is transported in a conveying direction 9.
- a plenum 6 Below of the cooling grate 1, a plenum 6 is formed, which of a cooling gas supply device (not shown) cooling gas is supplied to finally through the cooling grate 1 to be fed to the kiln 8 for cooling.
- the cooling grate 1 is on two, transverse to the conveying direction 9, I-shaped main beams 2 arranged. The simplicity only two of these main beams 2 are shown for the sake of however, any number of the main beams 2 can be provided his.
- the top 32 of the longitudinal beam 3 is with a sawtooth-like serration 36 provided. At the ends of the The longitudinal beam 3, the serration 36 is designed so that when connected of an adjacent side member 3 at this end Jag 36 continuously passes. One deepening each Serration 36 forms a receptacle for one of the shaped profiles 4.
- the shaped profile 4 is of a Z-shaped shape. It has one plate-like central part 41, on the opposite An outer part 42, 43 is arranged at each end.
- the Outer parts 42, 43 are rectangular and in opposite Arranged in the direction of the middle part 41. This in Direction of conveyance 9 located at the rear of the outer part 42 diagonally above, while that lying in the direction of conveyance 9 forward Outer part 43 points obliquely downwards.
- a transition area between the middle part 41 and the outer parts 42, 43 is rounded on the inward-facing side 44 and on the opposite, outward-facing side 46 executed square.
- the shaped profile 4 lies with its rear outer part 42 completely and with its middle part 41 predominantly in one of the recesses of the serration 36 of the side member 3.
- the front outer part 43 protrudes freely from the serration 36.
- the shape and the distance of the serration 36 from a recess to the next one is chosen so that the shaped profile 4 with its front outer part 43, the outer part 42 'in the conveying direction seen forward profile shape 4 ' overlaps like a roof tile.
- the gas passage channel 5 runs between the mutually parallel outer surfaces 42 ', 43 straight.
- the position of the shaped profiles 4, 4 'relative to one another is due to the zacking 36 of the main carrier 3 determined.
- the gas passage channels 5 are in terms of their design through the design of the serration 36 and the shaped profiles 4 set.
- the width of the gas passage 5 is 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 hand certainly. Adjustments are not necessary. It is sufficient for the assembly of the cooling grate 1 that after Structure of the support structure 2, 3, the shaped profiles 4 in succession inserted into the serration 36 of the side member 3 and there be attached.
- the cooling grate 1 thus enables a high level Degree of prefabrication, so that on the construction site only the individual parts still need to be put together.
- the result is a cooling grate that has advantages on the one hand in terms of a simple structure as well as on the other hand the quality of the cooling gas flow.
- Cooling grate 1 it is in the inventive Cooling grate 1 is not necessary, individual parts in a certain to bring relative position to each other and then in to fix this position permanently.
- the relative location of the Parts, especially the shaped profiles 4 is due to the design the side member 3 already fixed and unchangeable. Assembly errors are largely excluded.
- the arrangement of the shaped profiles 4 transversely to the conveying direction 9 the advantage that the cooling grate 1 has a braking effect on the Firing material 8 affects.
- a braking effect may be desirable to ensure a sufficient residence time of the firing material in the Ensure cooler.
- the braking effect becomes advantageous thereby increasing the outer angles 46 that are in the bed of the firing material 8 protrude, have an angular edge and not, like the inner angles 44, are rounded.
- FIG. 2 Another embodiment of the cooling grate according to the invention is shown in Fig. 2. Parts that correspond to those shown in Fig. 1 shown first embodiment match provided with the same reference numerals.
- the shaped profile 14 has between its middle part 141 and its outer parts 142, 143 flattened transition areas 144, 145.
- the flattened Transition area 144 determines the installation position of the Shaped profile 14 with respect to a base, which is in Fig. 2nd is formed by a side member 13.
- the flattened Transition area 144 is achieved that the shaped profile 14th always in the correct angular position in relation to the side member 13 is attached. Assembly errors from their intended Position tilted shaped profiles 14 are thus practical as in the first embodiment locked out.
- the distances between the shaped profiles 14 are not determined by the longitudinal beam 13, but can can be freely selected during assembly. So that the expanse of the gas passage channel according to the distance between two neighboring ones Shape profiles 14, 14 'are changed.
- the side member 13 usually there is an equidistant arrangement of the shaped profiles 14 the side member 13, but variations can be made to be replaced by another at certain points or a narrower gas passage channel a larger one or smaller volume flow of cooling gas to the one to be cooled To carry firing material. So it can be recommended in areas with high cooling capacity requirements, the shaped profiles 14 with less Set a distance from each other in order to have a larger width to achieve the gas passage channels 15.
- Such variations but are not limited to differences in terms to take into account the cooling power requirement, but can also be used to advantage to compensate for the supply of cooling gas. So is often found far from the cooling gas supply facility distant parts of the plenum 6 a lesser Pressure of the cooling gas; to compensate, there are the shaped profiles 14 arranged closer so that there is a larger width of the gas passage channels 15 results and thus the cooling gas supply via the entire cooling grate 1 is evened out.
- Cooling grate is a third embodiment of the invention Cooling grate shown. Parts that correspond to those shown in Fig. 1 shown first embodiment match provided with the same reference numerals. Unlike that In the first exemplary embodiment, the longitudinal beam 23 is straight Top 232 on.
- the shaped profiles 24 are in their central part 241 and its outer part 242, 243 rounded. The angles between the outer parts 242, 243 and the middle parts 241 rounded, so that overall an S shape rather than a Z shape as in the first embodiment results. Between the outer part 243 rear molded profile 24 and the outer part 242 'of a front Form profile 24 ', a gas passage 25 is formed.
- the Gas passage 25 itself is relatively short Length and great width; however, it is closed by an inlet area 251 and a mouth area 252.
- the outer part 243 is attached to the central part 24 in such a way that a harmonic Transition results; the same applies to the attachment of the outer part 242 'on the shaped profile 24'.
- a double deflected gas passage which, however, is very aerodynamically designed.
- the shape profiles according to the first, second and third embodiments are executed point symmetrical. Thereby can achieve a simple construction of the cooling grate also increases the risk of assembly errors confused positioning practically avoided.
- the shaped profiles 34 are at this embodiment is not point-symmetrical. They have a middle part 341, in which the a right-angled end in the conveying direction Outer part 343 connects. On the in the conveying direction the rear end is a hook-shaped outer part 342 arranged at an obtuse angle on the middle part 341.
- the shaped profiles 34 are usually in one piece carried out, but ultimately it can here as well as with the Shape profiles of the other embodiments stand there whether they are made in one or more parts.
- the rear outer part 342 is flat with its lower side and can be attached to the longitudinal frame 33 in this way, without the need for alignment work with regard to the angular position are.
- the distance between the shaped profiles 34 is usually chosen equidistant, but can be varied to To produce gas passage channels 35 of different widths.
