Can produce a large amount of high temperature flue gases in the production process in fields such as petrochemical industry, electric power, coal chemical industry, smelting, and contain a large amount of granule floaters in the flue gas, corrosivity is strong, in order to prevent that the flue gas from directly entering into the air, uses sealed baffle on zero leakage flue usually. The sealing retainer rings used on the existing commonly used sealing retainer plates are directly welded on the shell of the retainer plate, and the sealing retainer rings do not have release space when being heated and expanded and can only be bent and deformed, so that a gap is generated between the retainer plates and the sealing strips, and the leakage of smoke is caused. Therefore, the conventional sealing structure has poor sealing performance and is troublesome to replace.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing a simple structure, good, the convenient seal structure of change for flue of leakproofness to the not enough of prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a sealing structure of a sealing baffle for a flue comprises a circular fixing plate fixedly arranged on the inner side of the sealing baffle, wherein a retainer ring is arranged on the fixing plate, and a gasket is arranged on the retainer ring; the inner side of the sealing baffle is located at the outer side of the fixing plate, a plurality of mounting plates are uniformly distributed and fixedly arranged on the outer side of the fixing plate, mounting holes are formed in the mounting plates, limiting holes corresponding to the mounting holes are formed in the gaskets, and the check rings and the gaskets are tightly propped against the fixing plate through the pressing bolts arranged in the mounting holes and the limiting holes.
According to the technical scheme, the fixing plate is fixedly welded on the sealing baffle plate, the sealing retainer ring is tightly pressed on the fixing plate through the compression bolt, the space for preheating and free expansion of the sealing retainer ring is provided, deformation of the sealing retainer ring is avoided, sealing performance of the sealing retainer ring is ensured, the gasket is convenient to position the retainer ring, the sealing retainer ring is in close contact with the fixing plate, and meanwhile the structure is convenient to disassemble and replace, and the retainer ring is convenient to replace.
Preferably, an annular fixing groove is formed in the inner side of the upper plate surface of the fixing plate, a plurality of clamping grooves are uniformly formed in the retainer ring and located right above the fixing groove, and flexible positioning blocks penetrate through the clamping grooves and the fixing groove and are used for positioning the retainer ring. And the check ring is positioned to ensure that the check ring and the sealing baffle are concentric all the time.
Preferably, a plurality of grooves are formed in the upper plate surface of the fixing plate, flexible lower sealing strips are respectively arranged in the grooves, and the height of each flexible lower sealing strip is larger than the depth of each groove.
Preferably, the bottom of packing ring is equipped with inlays the groove inlay the inslot and be equipped with flexible upper seal strip, flexible upper seal strip highly be greater than inlay the degree of depth in groove.
The flexible upper sealing strip and the flexible lower sealing strip enable a certain space to exist between the retainer ring and the fixing plate as well as between the retainer ring and the gasket, and the gasket expands when being heated, so that the gasket has a proper telescopic space, deformation of the retainer ring is avoided, and the sealing effect of the retainer ring is ensured.
Preferably, a plurality of expansion gaps are uniformly distributed on the retainer ring. The expansion joint also prevents that the retaining ring from being heated and warp, makes it obtain effective extension after the thermal expansion to avoid the retaining ring to lead to the baffle to leak because of being heated and warp.
The utility model has the advantages that:
the utility model discloses convenient to use, convenient to detach change, the retaining ring can effectively be extended after the thermal expansion, and the leakproofness is good, and effectively avoids the retaining ring to lead to the leakage of baffle because of the thermal deformation.
