Description
Technical field
This utility model relates to boiler structure technical field, is specially a kind of sealing structure for suspending boiler top wall pipe in midair.
Background technology
Current suspended boiler is generally the roof tube of film water cold wall structure for boiler top, and wall pipe is generally superheater, reheater and column pipe. At top, the sealing structure at place through walls is generally adopted steel plate case and adds the structure that circular casing plug aluminosilicate fiber cotton is fixing for they, as shown in Figure 1. Under boiler operatiopn state, high-temperature flue gas flows through each place through walls, this structure is adopted to can be good at ensureing to seal, but wall pipe produces thermal expansion after being heated, and there occurs the change of displacement relative to bag wall ceiling, cause and produce stress in wall pipe and the junction sealing steel plate, if displacement is excessive, sealing steel plate can be torn, causing blow-by, even can cause pipe torsional deformation, this can give significantly, and boiler is properly functioning causes very big threat. Meanwhile, circular sleeve structure quantity is in the majority, and when processing cost height, installation, workload is big.
Summary of the invention
In order to solve the problems referred to above, this utility model provides a kind of sealing structure for suspending boiler top wall pipe in midair, its free wxpansion after ensureing to ensure again to be heated while place through walls seals, and will not damage pipe.
Its technical scheme is such that a kind of sealing structure for suspending boiler top wall pipe in midair, it roof tube including lateral arrangement and the wall pipe being vertically arranged, described roof tube is installed by welding with steel plate case, described steel plate case has the first perforation, it is characterized in that, described steel plate case upper end connects end plate by expansion joint, described end plate has the second perforation, described wall pipe runs through described steel plate case, expansion joint, end plate, gap is left between described wall pipe and described first perforation inwall, welded seal between described wall pipe and described second perforation inwall.
It is further characterized by, and described expansion joint is formed by polylith V-arrangement thin plate;
It is further characterised by, described V-arrangement thin plate lateral arrangement, described expansion joint is welded described end plate by four pieces of described V-arrangement thin plate upper ends, lower end is welded to connect described metal cap hull shape and becomes the rectangular configuration of all round closure, and described V-arrangement thin plate does not contact with described wall pipe;
It is further characterized by, and runs through multiple described wall pipe in a described expansion joint;
Described steel plate case and described end plate are spliced to form by multi-disc combed plate;
It is filled with insulated pouring material in described steel plate case, described wall pipe is provided with bitumen layer or is tied with aluminosilicate fiber cotton layer, in described expansion joint, being filled with aluminosilicate fiber cotton.
After adopting structure of the present utility model, add expansion joint structure, after expanded by heating, wall pipe can be vertically movable under the effect of expansion joint, pipe will not cause torsional deformation to damage pipe, be ensure that the sealing at place through walls by the welded seal of expansion joint, wall pipe and end plate.

Detailed description of the invention
See Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, a kind of sealing structure for suspending boiler top wall pipe in midair, it roof tube 1 including lateral arrangement and the wall pipe 2 being vertically arranged, roof tube 1 is installed by welding with steel plate case 3, steel plate case 3 has the first perforation 4, steel plate case 3 upper end connects end plate 6 by expansion joint 5, and end plate 6 has the second perforation, and wall pipe 2 runs through steel plate case 3, expansion joint 5, end plate 6, gap, welded seal between wall pipe 2 and the second perforation inwall is left between wall pipe 2 and the first perforation 4 inwalls.
Expansion joint 5 is formed by four pieces of V-arrangement thin plates 7, V-arrangement thin plate 7 lateral arrangement, expansion joint 5 is welded to connect metal case 3 by four pieces of V-arrangement thin plate 7 upper end welded end plate 6, lower end and forms the rectangular configuration of all round closure, convenient processing and installation, and V-arrangement thin plate 7 does not contact with wall pipe 2.
In Fig. 4, Fig. 5, in an expansion joint 5, all run through multiple wall pipe 2, it is possible to by all wall pipes 2 by an expansion joint 5, it is also possible to by triplet by an expansion joint 5.
Steel plate case 3 and end plate 6 are spliced to form by multi-disc combed plate, enormously simplify installation workload.
It is filled with insulated pouring material in steel plate case 3, wall pipe 2 is provided with bitumen layer or is tied with aluminosilicate fiber cotton layer, in expansion joint 5, being filled with aluminosilicate fiber cotton.
