Abstract
The utility model discloses a sealing structure of a wall-penetrating body of a horizontal pipeline of a waste heat boiler. The sealing structure is characterized by comprising a sealing plate which is arranged on a wall plate, a round hole which the wall-penetrating pipeline can just penetrate through is formed in the sealing plate, and pressing plates are arranged on two sides of the sealing plate. The sealing structure has the advantages of being simple in structure, good in sealing effect, safe, capable of guaranteeing the smooth expansion of the wall-penetrating pipeline and the like.
Description
Technical field
The utility model relates to the hermetically-sealed construction of a kind of waste heat boiler horizontal pipe body through walls, belongs to field of boilers.
Background technology
Waste heat boiler body flue front wall and both walls all have many pipelines through walls, these pipelines are along with boiler heating surface down expands together, during boiler operatiopn, because pipeline through walls will expand downwards, therefore have macropore in the poling road of body of wall part, being beneficial to pipeline through walls expands smoothly, reveal from the body of wall tapping for preventing flue gas, perforate partly seals need to body of wall, in traditional structure, often seal with expansion joint in the body of wall outside, and in body of wall inside (fume side), then seal with high temp glass cloth.
But because this position through walls is in preboiler body flue gas import department, flue-gas temperature is higher, and this partial fume washes away seriously, in actual motion, the situation that the drawing crack of high temp glass cloth, embrittlement often occur even burn out causes high temp glass cloth to damage, and makes flue gas directly enter expansion joint by the body of wall perforate, thereby burn out expansion joint, even burn out outside wallboard.
Summary of the invention
The purpose of this utility model is to solve not seal in body of wall inside, and cause burning out expansion joint and outside wallboard, make the problem that flue gas is revealed from the body of wall tapping, the hermetically-sealed construction of the waste heat boiler horizontal pipe body through walls of a kind of simple in structure, good sealing effect, safety, the smooth and easy expansion of assurance pipeline through walls is provided.
In order to achieve the above object, the utility model provides the hermetically-sealed construction of a kind of waste heat boiler horizontal pipe body through walls, it is characterized in that, comprise sealing plate, sealing plate is located on the wallboard, and sealing plate is provided with one just can hold the circular hole that pipeline through walls passes, and the both sides of sealing plate are provided with pressing plate.
Preferably, on the described sealing plate diameter of circular hole less than the diameter of porthole on the wallboard.
Preferably, described pressing plate is stepped ramp type.
Preferably, an end of described pressing plate perk and the distance between the wallboard are greater than the thickness of sealing plate.
Preferably, an end of described pressing plate is connected with wallboard, is provided with sealing plate between an end of pressing plate perk and the wallboard.
Preferably, the quantity of described pressing plate is at least 2.
Preferably, described sealing plate is to be spliced by at least 2 blocks of plates.
The utility model is simple in structure, be at a kind of hermetically-sealed construction of the inner increase of body of wall, no matter how pipeline through walls expands, sealing plate all is close to wallboard, to guarantee the good sealing effectiveness of waste heat boiler, can prevent to greatest extent that flue gas from scurrying in the expansion joint of wallboard outside, both guaranteed the safety of expansion joint, outside body of wall and boiler, can also prevent the outflow of flue gas heat and waste, thereby promote the efficient of waste heat boiler.Sealing plate can also move freely with pipeline through walls, can at utmost guarantee the smooth and easy expansion of pipeline through walls.

The specific embodiment
For the utility model is become apparent, now with preferred embodiment, and conjunction with figs. is described in detail below.
Embodiment
The utility model is the hermetically-sealed construction of a kind of waste heat boiler horizontal pipe body through walls, as shown in Figure 1, is the structural representation of the hermetically-sealed construction of a kind of waste heat boiler horizontal pipe body through walls.Sealing plate 1 at a band of pipeline 4 covers through walls circular hole, prevent to greatest extent that for making flue gas from scurrying into body of wall perforate (being porthole 3) by the circular hole of sealing plate 1, Circularhole diameter on the sealing plate 1 is slightly larger than pipeline 4 external diameters through walls, guarantee the smooth and easy circular hole that passes sealing plate 1 of pipeline energy, and can stop flue gas to be scurried into from the circular hole of sealing plate 1 again to greatest extent, namely this circular hole just can hold pipeline 4 through walls and passes.The diameter of circular hole is less than the diameter of porthole 3 on the wallboard 5 on the sealing plate 1, and sealing plate 1 can move up and down in porthole 3 with pipeline 4 through walls.With at least 2 pressing plates 2 sealing plate 1 is pushed down and to be touched wallboard 5, prevent that flue gas from scurrying into porthole 3.The back side of wallboard 5 is equipped with expansion joint 6.Pressing plate 2 is installed in the both sides of sealing plate 1, and pressing plate 2 is stepped ramp type.For effectively touching sealing plate 1, be unlikely to influence sealing plate 1 again with pipeline 4 free wxpansions through walls, an end and the distance between the wallboard 5 of pressing plate 2 perks are a bit larger tham sealing plate 1 thickness.One end of pressing plate 2 is fixed on the wallboard 5, and sealing plate 1 places between the end and wallboard 5 of pressing plate 2 perks.Install for ease of the scene, sealing plate 1 is to be spliced by at least 2 blocks of plates.
In the present embodiment, the quantity of pressing plate 2 is 4, and swell increment is bigger up and down to consider pipeline, 2 both sides that are fixed on sealing plate 1 of pressing plate, and sealing plate 1 is to be spliced by 2 blocks of plates.
The utility model is at a kind of hermetically-sealed construction of the inner increase of body of wall, when guaranteeing pipeline free wxpansion, effectively stops flue gas to flow out, thereby guarantees the safety of expansion joint even outside body of wall.
The utility model can seal porthole 3 when pipeline through walls 4 body 5 through walls, guaranteeing the sealing effectiveness of waste heat boiler, thereby promotes the efficient of waste heat boiler, guarantees the waste heat boiler safe operation.
