Definitions
- the invention relates to a firing grate for a combustion furnace, in particular for the incineration of garbage, with grate bar rows covering a downwind area and consisting of grate bars adjoining one another with side cheeks, the side cheeks of two adjoining grate bars being molded onto the underwind area and being connected to one another via removable coupling elements.
- grate bars must not be fixed too rigidly, since some of them must be quickly and easily removable if damaged.
- a bolt is formed on the side of the head of a grate bar and can be inserted into a blind hole in the neighboring grate bar.
- Another possibility is to connect all the heads of the grate bars of a row of grate bars by means of a bar transverse to the direction of flow of the material to be burned, the grate bars being under lateral spring pressure in order to permit thermal expansion.
- the disadvantage here is that to replace a
- the inventor has set itself the goal of eliminating the identified disadvantages and of creating a firing grate of the type mentioned at the outset, which ensures the desired sealing and is also easy to handle, in particular allowing simple replacement of defective grate bars.
- the connection should be form-fitting, but allow for thermal expansion and allow the relative movement of two grate bars towards one another and at the same time keep the uncontrolled air passage and the grate diarrhea between two grate bars low.
- the projections protrude from the side cheek with a shoulder heel and are encompassed by a common coupling element.
- the strip-like projection formed on the edges preferably allows two adjacent side cheeks to lie closely together. This is encompassed by the projection so that it has the shape of a foot in cross-section in the area of a rib or bar, the side cheeks resting against one another with the heels, which ensures that the space between two grate bars is almost eliminated.
- the coupling element intended for this rib consists of the section of a rectangular hollow profile with a cavity, one side of which has a slot with a width which corresponds to at least twice the wall thickness of the side cheek.
- the cavity itself has a height that corresponds to the height of the projection and a width of at least twice the wall thickness of the side cheek plus twice the thickness of the projection.
- the coupling element designed in this way can be pushed in a simple manner over two adjacent side cheeks or ribs and hold them together - and thus the associated grate bars. If a defective grate bar is to be replaced, only the two or more grate bars coupled with it need to be lifted, the coupling element removed from the ribs, the grate bar lifted out of its anchoring, a new one inserted and the coupling element pushed back over the ribs. This repair takes very little time.
- the coupling element holds the grate bars tightly together, wherein according to the invention the ribs are formed at locations with a favorable clamping effect, namely approximately in the middle of the underside of the grate bar. Penetration of fuel or slag parts into the interstices occurs extremely rarely, an undesirable underwind passage is excluded.
- the invention also includes internally of the coupling element on the clamping jaws arranged clamping elements, which ensure the positive fit both with cold and hot grate bar equally. It is intended here for traceable compression springs or leaf springs, or also pressure rollers mounted against the return force of an energy store, the latter making it easier to push the coupling element onto the strips.
- the coupling element is secured against slipping at least at one end by a single stop. If both ends of the coupling element are to be provided with stops, one of them must be removable.
- the coupling element is secured against displacement at least on one side cheek or a projection.
- This can e.g. B. happen by a bolt engaging from the outside of the coupling element in a blind hole in the projection.
- this pin can be removed from the blind hole by means of a rocker arm against the return force of an energy store.
- one of the two corresponding blind holes can be designed as an elongated hole, in order to enable the two grate bars to move relative to one another.
- Another advantage of this coupling is its simple and inexpensive manufacture, while maintaining a high degree of flexibility during the work process.
- a firing grate F has rows of grate bars 2 which are arranged in steps, overlapping like roof tiles, and are delimited by side walls 3. The latter close off a so-called underwind area, which is covered by the grate bar rows 2.
- a stationary grate bar row 4 and a grate bar row 5 movable in the flow direction x alternate in the flow direction x of a product not shown.
- Each of the movable grate bar rows 5 is connected by arms to a shaft 1 which penetrates the side wall 3 and is coupled to a drive 8 via a lever system 7. Only one drive 8 with the corresponding lever system 7 and the shaft 1 is shown as an example.
- Both the stationary and the movable grate bar rows 4 and 5 are formed by a plurality of grate bars 10 claw-like shape.
- the grate bars 10 of the movable grate bar row 5 are articulated on the one hand by means of a semi-cylindrical indentation 11 to a grate bar support 6 and are on the other hand with a claw tip 12 on the grate bars 10 of the grate bar row 4 following in the flow direction x.
- a box-shaped middle part 13 with a cover part 14 and two side cheeks 15 extends between the indentation 11 and the claw tip 12 (FIG. 3).
- the grate bar 10 ends with an inclined end face 16, from which end ribs 16m protrude.
- the side walls 15 carry ribs 17 which are formed on the underwind area and which, in the embodiment of FIG. 4, protrude from the side walls 15 as a projection 20 forming a shoulder shoulder 19 and also allow the side walls 15 of two adjacent grate bars 10 to lie against one another.
- a coupling element 22 which consists of a section of a box-shaped hollow profile, one side of which has a longitudinal slot 23, the width b of which corresponds to at least twice the wall thickness d of the side wall 15.
- the cross-sectionally approximately rectangular cavity 24 of the hollow profile 22 has a height h, which corresponds to the height g of the projection 20, and a width c, which is somewhat larger than twice the wall thickness d plus twice the cantilever width f of the projection 20.
- the longitudinal slot 23 allows two adjacent strips 18 of two side walls 15 to be inserted into the cavity 24, a simple stop 25 being provided in FIG. 5 to limit the insertion depth.
- a leaf spring 26 according to FIG. 6, which is subjected to pressure, is present on at least one side wall 27 of the clamping element 22 acting as a clamping basin in the cavity 24.
- a pin 29 projecting into the cavity 24 is provided, which engages in a blind hole 30 of the strip 18 or the projection 20.
- the bolt 29 can be removed from the blind hole 30 again by means of a rocker arm 32 that can be guided against an energy store 31, and the coupling element 22 can thus be released.
- a further securing possibility of the coupling element 22 detects a wedge 33 which is inserted into an incision 34 crossing the longitudinal slot 23 and is held on both sides by a locking plate 35.
- the shoulder shoulders 19 and the molded strips 18 are also cut.
- the width i of the incision 34 is selected so that the relative movement of two adjacent grate bars is possible.
