Abstract
The utility model discloses a high temperature non-metal compensator for a CFB boiler with features of no blockage of a dilation joint, no fall-off of a seal ring, good temperature resistance and long service life, comprising a main body comprising a metal frame and a casting layer, a cover around the main body, a dilation joint in the main body, a baffler in the dilation joint and a combined wear plate arranged at one side of the baffler. The high temperature non-metal compensator is suitable for the outlet position connection of the CFB boiler furnace-the cyclone separator.
Description
Technical field
The utility model relates to a kind of compensator, relates in particular to the non-metal compensator of a kind of CFB of being used for boiler furnace-cyclone separator outlet.
Background technology
Burner hearth-cyclone separator compensator is in the high temperature emulsion zone of CFB boiler, the work condition environment complexity, and mill run is in use, occurring adiabatic sealing ring easily comes off, framework serious distortion distortion, the heat insulation layer material scatters and disappears, phenomenons such as covering burns, tears, dilatation joint dust stratification, obstruction.
The utility model content
The technical problems to be solved in the utility model provide a kind of dilatation joint do not have obstruction, sealing ring do not have come off, temperature tolerance is good, the CFB boiler Non-Metallic Expansion Joints of long service life.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises body, the covering of being located at the body periphery be made up of metal framework and pouring layer, is located at intrinsic dilatation joint, is located at the deflector in the dilatation joint, and described deflector one side is provided with the combined type wear strip.
As preferably, described deflector is positioned at the medium channel inboard and also is provided with the anticreep plate.
As preferably, described metal framework is provided with the reinforcement gusset.
As preferably, described dilatation joint is positioned at the body center, is provided with sealing gasket in the described dilatation joint, and described sealing gasket is made by the alloy silk fine cloth parcel aluminium silicate wool of making pottery.
As preferably, be provided with two-layer thermal insulation layer between described wear strip and the covering, form by the ceramic fibre global formation of heatproof at 1250 ℃.
As preferably, be provided with fixation kit in the described two-layer thermal insulation layer, described fixation kit is fixedlyed connected with wear strip.
The utility model compared with prior art has following obvious advantage and beneficial effect:
1, dilatation joint does not have obstruction, sealing ring does not have and comes off.Because the utility model deflector is provided with the anticreep plate, not only can avoid the dilatation joint dust stratification, and make sealing ring avoid coming off.
2, wear-resisting, temperature tolerance good.Because the utility model not only adopts the combined type wear strip, and adopts two-layer thermal insulation layer between wear strip and the covering, thereby improved wear-resisting and heat resistance.
3, long service life.Do not have and come off because dilatation joint has obstruction, sealing ring in the utility model, and wear-resisting and heat resistance good, thereby improved product service life.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail: as shown in drawings: the utility model comprises the body of being made up of metal framework 1 and pouring layer 2, the body periphery is provided with covering 3, metal framework 1 is provided with strengthens gusset 5, can improve the intensity of metal framework 1 like this, be provided with dilatation joint in the body, dilatation joint is positioned at the body center, be provided with sealing gasket 6 in the dilatation joint, can avoid when boiler startup, the cyclone separator of negative pressure state directly siphons away sealing ring; Sealing gasket 6 is made by the alloy silk fine cloth parcel aluminium silicate wool of making pottery, be provided with deflector 7 in the dilatation joint, deflector 7 is positioned at medium channel 8 inboards and is provided with anticreep plate 9, deflector 7 opposite sides are provided with the combined type wear strip, the combined type wear strip that is positioned at body the first half and the latter half is also asymmetric, wherein the first half arrangement form is a labyrinth type, the wear strip 10 that is yi word pattern by the vertical section shape is formed with the wear strip 11 that the vertical section shape is the Z font, the latter half arrangement form is a run-in index, its vertical section shape all is the wear strip 12 of yi word pattern, 13 form, the utility model inside that can avoid the difference in height of boiler furnace and cyclone separator to cause is like this watered material feeding and is produced synchronous difference in height, thereby reduce the flow area of furnace outlet, and the anticreep plate that makes exposure is subjected to the erosive wear of granule medium, influences service life of the present utility model; Be provided with two-layer thermal insulation layer 15,16 between combined type wear strip and the covering 3, form by the ceramic fibre global formation of heatproof at 1250 ℃, be provided with fixation kit 17 in the two-layer thermal insulation layer 15,16, fixation kit 17 is fixedlyed connected with the combined type wear strip, fixation kit 17 can adopt bolt, can guarantee like this in that the utility model is hot when being subjected to displacement, thermal insulation layer can be followed expansion direction of the present utility model and be moved, effectively stop leaking of hot flue gas, when the utility model cold conditions, thermal insulation layer again can be very fast is returned to reset condition.
