Definitions
- the present invention relates to the formation of a diarrhea-free grate from interlocking lamellar bodies for receiving bulk goods during their combustion, cooling or other treatment, in particular for cooling fired bulk goods, by means of a gas flowing between the lamellar bodies.
- the grate floor is formed from grate plates which are fastened to grate supports in such a way that the grate plates overlap in the longitudinal direction in a scale-like manner and are alternately stationary or movable back and forth in the longitudinal direction of the grate, as described in patent DE-PS 952 785.
- the grate plates have openings on the surface through which the cooling medium, preferably air, is fed to the bulk material lying thereon. These grate plates are usually mounted on grate supports.
- the disadvantage of the known construction is that the grate plates are cast or welded from one piece. With different heat input, e.g. Cooling air from below and very hot material from above, the grate plates warp and / or tear. A reduction in the size of the grate plates and grate supports is not economical and increases the number of slide and side gaps and thus the undesired grate diarrhea caused by these gaps. Bulk material can also fall through the openings in the surface and cause wear. In addition, a transport system is required to dispose of the grate diarrhea.
- the grate plate has been replaced by a grate bottom element in the form of a box, as in the patent DE 33 32 592 C1.
- This box is attached to a grate support called an air bar.
- the cooling medium is fed directly to the air bar via several line connections and from there it is further distributed to the box-shaped grate floor elements.
- the box-shaped grate floor element also referred to as the grate plate, opens up the Possibility that the grate surface is formed by overlapping profiles that reduce the grate diarrhea.
- Rust plate is and can only be replaced as a whole.
- Rust surface no material separate from the box can be used.
- Grate plates can only be fixed on the grate supports when closed and, due to the lack of accessibility, the attachment to the adjacent ones
- Rust plates and the rust support is complicated.
- a patent EP 0 549 816 B2 describes a box-like grate floor element
- Frame end wall is formed with a lower wall height than the side walls, whereby the frame is statically weakened.
- Lamellar bodies are required.
- Another disadvantage of the known construction is that the formation of a flat grate floor from box-shaped grate floor elements is only possible to a limited extent, since access to the front of the box-like grate floor element must be provided in order to change the slat body.
- a grate element A grate element.
- Another disadvantage of the known construction is that changing an individual lamella body is time-consuming.
- Grate support is connected.
- a grate floor is formed, which consists of small, thermally insensitive lamellar bodies with sufficient thermal expansion joints, and in which the lamellar bodies have a form fit that is preferably limited to one degree of freedom.
- the grate floor formed in this way can be designed to be extremely advantageous and versatile with regard to the gas passages, in particular if the gas passage opening between the lamella bodies is formed by joining the lamella bodies together. It is particularly advantageous to design the gas outlet opening as a slot that is inclined in the transport direction over the entire width of the lamellar bodies. By overlapping the lamellar bodies, the gas slot can be formed with a trough below the grate surface in such a way that no bulk material can fall under the grate floor.
- a flow around the L; - ⁇ me ⁇ enkörte ensures good cooling of the lamellar body and reduces thermal stresses.
- the positive locking of the assembled lamellar body and the free design of the attachment to a support structure enables the formation of thermal expansion joints to avoid warping and cracks.
- a particularly advantageous embodiment of the present invention is created in that a separation of the grate floor and support structure enables the versatile use of this grate floor on a wide variety of grates, for example for known stationary slanted grates in the radiator inlet area, driven sliding grates and grates with a flat grate floor and for various other grates on which bulk goods are transported and heat treated.
- the cover plate can be replaced relatively easily by the present invention of an interlocking form-fitting grate floor.
- the design of the box element is simple and, due to the open accessibility, in particular from above, when mounting, the best possible and easy attachment to the support structure, generally referred to as a grate support.
- the box element is also not statically weakened by further lateral openings or lowered end walls.
- the configuration of the support structure for receiving a grate floor according to the present invention is possible in a more versatile and cost-effective manner.
- the grate floor can also be fastened, for example, via a central locking device by means of a shaft, as described in the attached drawing, or via a recessed and thus protected fastening from above.
- the reduction of wear parts to that exclusively with the Contact surfaces to be conveyed are particularly advantageous, since the material for the grate floor is subject to different requirements than the support structure and the mass of wear parts is reduced.
- the present invention reduces the wear parts by separating the grate floor and support structure and, depending on the application, the connecting elements of the grate floor and support structure are completely protected and are no longer considered wear parts.
- a particularly advantageous embodiment of the present invention is created in that the generally highly thermally and wear-prone grate surface is essentially formed from identical and therefore more cost-effective slat bodies. This high proportion of identical parts is also particularly advantageous with regard to warehousing.
- the slat body (1) consists of a slat front part (2) forming the grate surface and a slat rear part (3) covered by the previous slat body.
- Profiles (4) are arranged laterally on the lamella front part (2) forming the grate surface.
- Counter profiles (5) are machined on the side of the slat rear part (3).
- Fig. 4 shows a plate pack (6) consisting of two plate bodies (1).
- a third slat body (7) is located in front of the plate pack (6).
- the profiles (4) and the counter profiles (5) are shaped and arranged in such a way that the lamellar bodies (1) can be pushed into one another.
- a straight, level grate surface is created.
- Fig. 5 shows a typical grate surface (8).
- the grate surface (8) is formed by individual lamella bodies (1) arranged one behind the other.
- Below the slat body (1) there is a box-shaped slat carrier (9), dimensioned and fastened in a similar way to, for example, a conventional modern grate plate.
- a grate plate on which the invention is based is to fasten the slat bodies (1), which are put together to form a slat package (6), on a box-shaped slat carrier (9), in that some slat bodies (1) have straps (10) on both sides, which have Align the corresponding tabs (11) in the disk carrier (9) and connect the disk body (1) and disk carrier (9) to one another using shafts (12) that are inserted through the disk carrier end walls (13).
- the openings for the shafts (12) in the slat carrier end walls (13) are preferably closed by adjustable front plates to reduce the shear gaps and thus the shafts (12) are secured against falling out.
- FIG. 6, 7 and 8 show how an even grate floor can be built up with an invention of the type mentioned in patent claims 1 and 2.
- a grate floor can advantageously also be provided with a central locking system.
- Tabs (14) are attached to the plate carrier (9) on each side. The eyes of these tabs are in alignment.
- a shaft (15) is inserted into the tab eyes pushed into it.
- This shaft (15) is machined on one side and therefore has a surface (16).
- the shafts (15) are rotated so that the surface (16) faces the respective outer sides of the disk carrier (9).
- the slat bodies (22) to be fastened are provided with swords (17) on the sides. These swords (17) are made wider at the bottom.
- the lamellar bodies (22) can be placed on the lamellar carrier (9). By rotating the shafts (15), the lamella body (22) is fixed. In this way, any length of grate floor can be built. 8 shows a section of FIG. 7
- the guide profile (18) is open.
- the slat rear part (19) acts as a counter profile (20).
- a positive connection is created by pushing a slat body (21) onto the previous slat body (23).
