The described rod seal structure that hangs also includes the upwardly extending tubular shell of upper surface from described sealed body, and this tubular shell around described sealing member and with this sealing member separately, is filled with buffer fillings parts between described tubular shell and described sealing member.
Preferably, described sealing member is the asbestos cord being wrapped on described suspension rod.
Preferably, described filling component is plastic refractory.
Preferably, described tubular shell is higher than described sealing member along the height of described suspension rod, described tubular shell is arranged around described suspension rod and described sealing member and with this suspension rod and sealing member interval, described filling component all it is filled with, thus the height of described sealing member is lower than the height of described filling component in clearance space between described sealing member, described suspension rod and described tubular shell.
Preferably, described filling component is filled in described clearance space by cast.
Preferably, described tubular shell is metallic cylinder.
Preferably, the top of described tubular shell is provided with the rain cover around described suspension rod, and this rain cover covers the top end opening of described tubular shell.
Preferably, described rain cover is fixed on described suspension rod, and along extending obliquely downward to riding over described tubular shell from described suspension rod radially outward direction.
This utility model also provides for a kind of boiler, and described boiler includes hanging as above rod seal structure, described in hang the furnace roof that described sealed body is described boiler in rod seal structure.
What this utility model provided hangs rod seal structure, by arranging the sealing member of the suspension rod that reclines, and between sealing member tubular shell and sealing member, it is filled with buffer fillings parts, can be well carried out the gap between suspension rod and sealed body sealing, and owing to filling component has cushioning effect, hang rod seal structure be applied to boiler etc. by time in thermal condition at this, filling component can absorbing thermal expansion, produce bigger thermal deformation and the problem that causes this sealing device poorly sealed thus not havinging because this hangs rod seal structure.
Other features and advantages of the utility model will be described in detail in detailed description of the invention part subsequently.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.It should be appreciated that detailed description of the invention described herein is merely to illustrate and explains this utility model, it is not limited to this utility model.
In this utility model, when not making contrary explanation, the noun of locality of the use word such as direction indications such as " upper and lower " or orientation is based on direction shown in the drawings or position relationship.
This utility model provides one to hang rod seal structure, this hangs rod seal structure and includes sealed body 1 and be through the suspension rod 2 on described sealed body 1, as depicted in figs. 1 and 2, this hangs rod seal structure and also includes the sealing member 3 of outer surface of the suspension rod 2 that reclines arranged around suspension rod 2, and the bottom of sealing member 3 is against on the upper surface of sealed body 1；This hangs rod seal structure and also includes from the upwardly extending tubular shell 4 of the upper surface of sealed body 1, and this tubular shell 4 around sealing member 3 and with this sealing member 3 separately, is filled with buffer fillings parts 5 between tubular shell 4 and sealing member 3.
What this utility model provided hangs rod seal structure, by arranging the sealing member 3 of the suspension rod 2 that reclines, and between sealing member tubular shell 4 and sealing member 3, it is filled with buffer fillings parts 5, can be well carried out the gap between suspension rod 2 and sealed body 1 sealing, and owing to filling component 5 has cushioning effect, hang rod seal structure be applied to boiler etc. by time in thermal condition at this, filling component 5 can absorbing thermal expansion, thus do not have because this hang rod seal structure produce bigger thermal deformation and cause the problem that this sealing sealing structure is not tight.Therefore, what this utility model provided hangs rod seal structure, can either ensure to seal reliably between suspension rod 2 and sealed body 1, moreover it is possible to ensure to cause because of thermal expansion deformation seal failure in application process.
In detailed description of the invention of the present utility model, sealing member 3 is preferably the asbestos cord being wrapped on suspension rod 2, this hang rod seal structure be applied in worst hot case time, this sealing member 3 is preferably high temperature asbestos cord.
Filling component 5 is filled with preferably by the mode of cast, and the material of this filling component 5 is preferably plastic refractory, it is more preferred to, plastic refractory is that high-temperature flame-proof is moldable, plastic refractory has fire resistance, but also has certain plasticity, it is possible to absorbing thermal expansion.
Certainly, this sealing member 3 is not limited to as asbestos cord, it is possible to for other the sealing member being capable of sealing.Filling component 5 is also not necessarily limited to as plastic refractory, it is possible to select other the material with cushioning effect with elasticity or plasticity.
In present embodiment, it is preferable that the height of sealing member 3 is lower than the height of filling component 5.Concrete, in Fig. 1, tubular shell 4 is higher than sealing member 3 along the height of suspension rod 2, tubular shell 4 is arranged around suspension rod 2 and sealing member 3 and with this suspension rod 2 and sealing member 3 interval, filling component 5 all it is filled with, thus the height of sealing member 3 is lower than the height of filling component 5, so in clearance space between sealing member 3, suspension rod 2 and tubular shell 4, the upper end of sealing member 3 can be enclosed in filling component 5 so that seal relatively reliable.
Tubular shell 4 is preferably metallic cylinder, and the bottom of this metal cylinder can be fixed by welding on the upper surface of sealed body 1.
Be provided with the rain cover 6 around suspension rod 2 on the top of tubular shell 4, this rain cover 6 covers the top end opening of tubular shell 4, and can prevent rainwater from entering in this sealing device affects sealing property.
Preferably, this rain cover 6 is fixed on suspension rod 2, and along extending obliquely downward to riding over tubular shell 4 from suspension rod 2 radially outward direction.Rain cover 6 is ridden on tubular shell 4, but not is fixed on tubular shell 4, can prevent rain cover 6 from expanding drive tubular shell 4 when being heated and be deformed.
This utility model also provides for a kind of boiler on the other hand, and this boiler includes hanging as above rod seal structure, and this hangs the furnace roof that sealed body 1 is described boiler in rod seal structure.
This boiler adopts and hangs rod seal structure as above, and the sealing of furnace roof is reliable, and does not have and make the sealing malformation of this suspension rod cause poorly sealed problem because boiler produces heat.
Preferred implementation of the present utility model is described in detail above in association with accompanying drawing; but; this utility model is not limited to the detail in above-mentioned embodiment; in technology concept of the present utility model; the technical solution of the utility model can being carried out multiple simple variant, these simple variant belong to protection domain of the present utility model.
