Definitions
- the invention relates to a device for attaching lining panels refractory ceramic material on a metallic wall, especially for a waste incineration plant, with metallic, slotted on the wall Anchor pins are attached that support the liner panels.
- the object of the invention is to provide a device of the type mentioned propose that simplifies the attachment of the lining panels.
- the above object is for a device of the type mentioned Art solved in that the anchor pin forms at least two resilient tongues and that radial projections are designed on the tongues, which behind one with the Lining plate in connection with the stop edge like a push button are snapped.
- the Lining plate with an opening forming the stop edge on the Anchor pin inserted and then pressed, the radial projections of the tongues Snap positively behind the stop edge.
- the tongues swing due to their elasticity. It is not necessary to use the anchor pin spreading a tool. Because the location of the projections on the tongues is established, it is also ensured that the lining plates in the desired orientation.
- the replacement of a defective lining plate is comparatively easy. This is removed from the anchor pin or broken away, after which a new one Snap the lining plate onto the exposed anchor pin.
- a cap on the ends of the tongues fireproof ceramic material plugged into an insulating compound can be embedded.
- a particularly safe corrosion protection of the anchor pin is achieved in a preferred embodiment of the invention in that the Lining plate is attached to a molding, which is one the ends of the tongues has receiving and forming the stop edge. Through the Dimensioning of the cavity in relation to the tongues is preferably done simultaneously also reaches a depth stop for the tongues, which improves the position of the Lining panel further improved.
- a combustion furnace for example a waste incineration plant, has one metallic tube wall (1) with water-carrying tubes (2) and connecting them Web (3) or fins on to the combustion chamber (4) are on the Pipe wall (1) lining plates (5) made of refractory ceramic material, in particular SiC material. The surface of the lining plate 5 can be wavy. Between this and the pipe wall (1) is an insulating and Compensation layer (6), for example made of ceramic fiber material.
- Anchor pins (7) made of metal, for example, are distributed on one of the webs (3) Spring steel, welded on.
- the anchor pin (7) has a round or rectangular one Cross-section. It has a longitudinal slot (8) next to the elastic one Tongues (9,10) exist.
- the anchor pin (7) can also be slit two or more times be, whereby there are correspondingly more resilient tongues.
- the Lining plate (5) has a conical recess (19), the Pipe wall (1) facing smaller opening forms a stop edge (20).
- Anchor pin (7) happens approximately as follows:
- the lining plate (5) with its opening forming the stop edge (20) put on the ends (13, 14) of the anchor pin (7) in the direction of the arrow (M), the ends (13, 14) easily fitting into the opening. To make this easier
- the opening can then be attached to the stop edge (20) with a Insertion bevel (21) may be provided. Then it is in the direction of arrow (M) Pressure is exerted on the lining plate (5). It slides under spring elastic Deformation of the tongues (9, 10) of the stop edge (20) on the front slopes (15.16). When he has overcome the front slopes (15, 16), he glides to the rear bevels (17,18) further, the tongues (9,10) resilient snap open.
- the lining plate (5) is now shown in FIG. 1 Position held. In order for the stop edge (20) to lie flat against the To achieve rear slopes (17, 18), the angle of the rear slopes (17, 18) the angle of the conical recess (19).
- the projections (11, 12) project radially beyond the cross section of the anchor pin (7) close to the web (3).
- the cross section of the anchor pin (7) close to the web (3) can also be as large or larger than the cross section in the area in which the front bevels (15, 16) into the pass over the rear slopes (17, 18).
- Recess (19) is aligned with the surface (5.1) of the lining plate (5).
- Compensating bore (26) may be provided.
- Cap (25) Through the seated in the insulating compound (24) Cap (25) is the anchor pin (7) against that in the combustion chamber (4) prevailing corrosive atmosphere and against the temperatures prevailing there, protected, for example, about 1200 ° C.
- an anchor pin (7) attached lining panels (5) arranged in rows overlapping. Between are two lining plates (5) attached to anchor pins (7) Intermediate plates (27) are provided, not on anchor pins, but thereby are held that they and the adjacent lining plates (5) stepped Have edges (28, 29), the stepped edges (29) of the Lining plates (5) the stepped edges (28) of the intermediate plates (27) overlap the combustion chamber (see Fig. 3). It is a single one Replacing defective lining plates (5) in a particularly simple way possible. To replace a destroyed lining plate (5), this is from their anchor pin (7) removed, for example broken down.
- Molded part (30) made of refractory ceramic material attached which is a special has low porosity, especially almost 0% porosity, and high strength owns.
- the molded part (30) can be fixed on the lining plate (5) by that it is in the manufacture of the lining plate (5) in the mass forming it is pressed in, a positive connection being produced via conical surfaces (31).
- the molded part (30) has a cavity (32) in which, following an opening (33) there is a rounded extension (34). According to this are the Projections (11,12) of the tongues (9,10) shaped.
- the lining plate (5) with its molded part (30) in the direction of the arrow (M) on the front slopes (15, 16) of the tongues (9, 10). This deform resiliently when passing through the opening (33) and then snap with their projections (11, 12) into the extension (34) of the Cavity (32).
- the tongues (9, 10) are found on the one hand on the bottom (35) of the Hollow (32) a stop and on the other hand find the rear bevels (17, 18) in the cavity (32) a stop.
- the lining plate (5) is thereby on Anchor pin (7) attached.
- the anchor pin (7) is in against the corrosive atmosphere of the combustion chamber (4) protected because it is opposite the combustion chamber (4) by the Lining plate (5) itself and covered by the molded part (30).
