Definitions

  • the present invention relates to a grate floor element for building up a grate floor of the type described in the preamble of claim 1, which is used, for example, to hold solids in their combustion, cooling or other heat treatment.
  • the slots remaining between the lamellar bodies are used to blow out a gas, for example air, which flows through the material lying on the grate bottom from bottom to top.
  • the gas can perform various tasks in a known manner, namely e.g. cooling the grate floor, cooling or heat treatment of the material lying on the grate floor, conveying this material, etc.
  • Such grate floors are generally subject to heavy wear. This applies in particular to the use of cooling cement clinker, which also has a high surface roughness with a high weight.
  • a grate floor element of the type mentioned in the preamble of claim 1 is already known from EP 0 167 658 B1.
  • This grate floor element consists of two basic components, each of which comprises a side web and a plurality of lamellar bodies which are integrally connected to the lamellar body spacing at twice the distance; the grate floor element is assembled by connecting two side webs so that the lamellar bodies of one side web grip between the lamellar bodies of the other side web and are inserted into receiving openings formed thereon.
  • the Basic components additionally screwed together, for example on the underside of the grate floor element.
  • a disadvantage of the known construction is that in the event of wear of individual lamellar bodies and / or side webs exceeding a permissible level, the entire grate floor element or at least entire base components must be replaced, in the latter case the connection holding the components together being released in a complex manner and after Replacing a basic component must be restored.
  • usable, non-worn parts of the grate floor element are also also replaced, which leads to high material costs; on the other hand, the disassembly or assembly process is lengthy, which regularly leads to longer downtimes for the entire system concerned.
  • the basic idea of the present invention is to divide the grate floor element into a frame that connects the two side webs to one another, as well as individual slat bodies that can be connected to this frame. This takes account of the fact that, above all, the lamellar bodies are subject to increased wear and must be replaced.
  • the construction according to the invention allows individual slat bodies to be replaced with little assembly effort, without at the same time replacing intact side webs.
  • the connection of the lamellar bodies to the side webs can be solved extremely simply in terms of construction, as will be described in more detail using several exemplary embodiments.
  • Another advantage results from the fact that the two side webs of a grate floor element no longer have to be screwed to one another in the manner described and have to be connected to one another in another way.
  • the division of the grate floor element according to the present invention thus follows the different functions of the side webs on the one hand, which preferably serve as mounting elements for the slat bodies, and these slat bodies on the other hand, which preferably form the grate surface and are therefore subject to preferential wear.
  • This division also makes it possible, for example, to manufacture the frame on the one hand and the lamella body on the other hand from different materials that are optimally adapted to their respective functions.
  • the side webs each run in the longitudinal direction as a guide rail have serving longitudinal guide profile, and that the lamellar bodies each have at their lateral ends a cooperating with an associated longitudinal guide profile counter profile.
  • This design enables a particularly simple assembly of the lamellar bodies by simply threading them one behind the other into the longitudinal guide profiles of the side webs.
  • the longitudinal guide profiles can be designed as grooves and the counter profiles accordingly as spring beads or vice versa, as is shown with the aid of different exemplary embodiments.
  • the side webs are formed by side walls parallel to one another and perpendicular to the frame plane, the side walls being connected to one another at least on a first frame front side by an end wall with a lower wall height than the side walls; the longitudinal guide profiles are then formed on the mutually facing inner surfaces of the side walls above this end wall, so that they can run into the end edges of the side walls on the first frame end face.
  • This construction makes it possible to line up the lamella body in a straight line from the first frame end face between the side webs, so that the entire grate floor element is a compact component that is smooth on the outside and can be connected in a gas-tight manner to other grate floor elements to form a grate floor.
  • the first frame end face is preferably the front end face in the conveying direction, which the one Wear corresponds to the area of the grate floor element that is most subjected to wear, so that the lamella bodies to be replaced are also the first to be accessible.
  • the lamellar bodies have spacing projections which are intended for contact with an adjacent lamellar body; these allow the lamellar bodies to be threaded one after the other into the longitudinal guide profiles up to the stop, these spacing projections also defining the gas outlet slot remaining between the lamellar bodies.
  • a further significant improvement in the sense of the division of tasks of the frame, on the one hand, and the slat body, on the other hand, is achieved in that the slat bodies each have at their lateral ends a longitudinal flange designed to cover the upper edge of an associated side web.
  • the longitudinal flanges lie on the upper edge of the associated side webs and cover them upwards.
  • the side webs are effectively protected against wear from the material lying on the grate floor, so that it is no longer necessary to replace the frame at all.
  • the lamella bodies in such a way that they each have a main section forming the grate floor surface and an extension that engages under an adjacent lamella body, that the mating profiles intended for engagement in the longitudinal guide profiles and the longitudinal flanges intended for covering the side webs are each formed only at the lateral ends of the main section.
  • a particularly simple solution provides a closing slat body which is equipped with means for locking the same to the frame.
  • This final lamellar body is inserted as the last lamellar body in the longitudinal guide profile and connected to the frame in any suitable manner so that it holds the other lamellar bodies.
  • the final lamellar body can be attached, for example, by welding, screwing, locking or in another known manner.
  • the frame has a bottom wall in its end region assigned to the first frame end face and a ceiling wall in its end region remote from the first frame end face, each grate floor element laying with the bottom wall on the top wall of a grate floor element following in the conveying direction of the material to be supported.
  • the front face of all grate floor elements always remains accessible even in the assembled state, so that individual slat bodies can be replaced without having to dismantle the associated frame.
  • the grate bottom element 8 which is formed from a preferably one-piece frame 2 and a multiplicity of lamella bodies 6 arranged one behind the other in the conveying direction indicated by the arrow 4, is placed on a grate carrier 10.
  • the grate carrier 10 is connected in a manner not shown to a gas supply line.
  • the frame 2 comprises two side webs 12, 14, which are formed as perpendicular to the main frame level side walls.
  • the side walls 12, 14 are connected to one another at their front frame end face 15 in the conveying direction by an end wall 16 which has a lower wall height than the side walls 12, 14, so that the side walls 12, 14 project beyond the upper edge of the end wall 16.
  • longitudinal grooves 18, 20 are formed on the mutually facing inner surfaces of the side walls 12, 14, which serve as longitudinal guide profiles for receiving lamellar bodies 6. These longitudinal grooves are arranged above the end wall 16 and run in the region of the front end of the frame into the end edges of the side walls, so that they are accessible from this side.
  • FIG. 4 shows a lamellar body 6.
  • This essentially consists of a main section 22 forming the grate floor surface and an attachment 24 arranged thereon, which in the manner shown in FIG. 1 engages under an adjacent lamellar body.
  • spring beads 26 and 28 are formed, which are complementary to the longitudinal grooves 18, 20.
  • the lamellar bodies 6 are threaded one behind the other from the front frame end 15 into the longitudinal grooves 18, 20.
  • spacing projections 30, 32 are formed, which abut the rear edges of the previously threaded lamella body 6. These spacing projections define the gas blowout slot 34 remaining between the lamellar bodies 6 (see FIG. 1).
  • the spacing projections can be easily reduced by grinding or increased by cladding so that the slot width can be varied.
  • a final lamellar body 36 is threaded last, which differs from a normal lamellar body 6 in that the main section 38 has, at its rear end in the direction of insertion, a lower end flange 40 which essentially extends to the upper edge of the end wall 16.
  • the end flange 40 on the one hand and on the end wall 16 on the other hand, means for locking the end plate body 36 to the frame 2 are formed.
  • at least one of the two adjacent edges of the End flange 40 and the end wall 16 a bevel, which enables the production of a connection weld 42 in a simple manner.
  • FIG. 6 shows a detail of another embodiment for the longitudinal guidance of the slat body in the frame.
  • FIG. 6 shows two adjacent side walls 44 and 46 of two grate floor elements arranged side by side in a grate row.
  • the side walls 44, 46 have at their respective upper ends a spring bead 48, 50 serving as a longitudinal guide profile, while the counter profiles arranged on the lamellar bodies 52 and 54 are designed as grooves 56 and 58 complementary to the spring beads.
  • the lamellar bodies 52 and 54 each have at their lateral ends a longitudinal flange 56 and 58 designed to cover the upper edge of an associated side wall 44 and 46. These prevent the side walls 44, 46 from being on the Rust lying material come into contact, so that wear is limited to the lamellar body, which can be replaced in a simple manner.
  • the frame 2 has a bottom wall 60 in its end area assigned to the first frame end face 15, which covers the area protruding beyond the grate carrier 10 from below.
  • the area of the frame placed on the grate carrier 10 is open at the bottom, so that gas from the grate carrier can enter the grate base element 8 and flow to the gas outlet slots 34.
  • the bottom wall 60 closes the frame 2 in a gas-tight manner in the area projecting beyond the grate carrier 10.
  • the frame 2 In its end region remote from the first frame end face 15, the frame 2 is covered by a ceiling wall 62.
  • the first slat body is placed on the end edge of the ceiling wall facing the front end of the frame.
  • the top wall In its area facing the first end face of the frame, the top wall is preferably profiled in a manner similar to the main section 22 of a lamellar body, so that a gas blowout slot is likewise formed between the top wall and the shoulder 24 of the first lamellar body.
  • Figures 1 and 2 each show a hatched area designated 64, which characterizes the usual wear pattern of a grate floor element.
  • the front regions in the transport direction of the material to be supported preferably wear out.
  • the weld 42 which fixes the end lamellar body 36 is severed, so that the front lamellar body can be removed and replaced by new ones.
  • the wear on the upper edges of the side walls 12, 14 is compensated for, for example, by cladding.
  • FIG. 1 schematically shows the arrangement of a further grate floor element 70, arranged in the transport direction 4 in front of the grate floor element 2, of a further grate row, which is arranged in a step-like manner downwards.
  • the upper grate floor element 8 overlaps the lower grate floor element 70 at most in the area of the ceiling wall 62, so that the effective grate floor area is not reduced.
  • the front end face of all grate floor elements remains accessible due to the stepped arrangement, so that the preferably wear-resistant lamellar bodies 6 can be replaced without dismantling the grate floor elements.
  • Other wear-related repair work such as the build-up welding of the side walls 12, 14 is also possible from above without dismantling the grate floor elements.
