Description
Technical field
The utility model relates to boiler seal technical fields, and in particular to a kind of boiler labyrinth-type excluder.
Background technique
The leakproofness of boiler has very big influence to the economy of boiler operatiopn, as boiler seal it is not tight caused by leak
Wind will cause burning difficulty, increases unburned carbon loss, increases excess air coefficient, can not only greatly increase boiler
Heat loss due to exhaust gas, cause additional air inducing power consumption, it is also possible to influence normal combustion process in furnace.
It is connected and sealed by the way of grafting between existing boiler and external flue, but due to boiler and outer cigarette receiving
The volume in road is larger, boiler in combustion boiler and external flue junction because boiler nozzle and external flue heat
The coefficient of expansion is different, is easy to appear formation gap or outlet flue between outlet flue and external flue and is located at external flue splicing position
There is slight crack because expansion is less than external flue (outlet flue) in the outlet flue (external flue) in outside, influences sealing effect.
Summary of the invention
For the problems of in the prior art, a kind of boiler labyrinth-type excluder provided by the utility model,
It is matched respectively with steel plate, right angle frid by trough plate, is flexibly connected realization between outlet flue and external flue, is conducive to
The thermal expansivity between boiler and external flue is improved, while flue gas can effectively avoid by trough plate directly impacts asbestos and filling out
Material is conducive to improve sealing effect.
To achieve the goals above, the technical solution adopted in the utility model is as follows:
A kind of boiler labyrinth-type excluder including the outlet flue on boiler and is plugged on external in the outlet flue
Flue, the outlet flue is interior to be equipped with the crossbeam matched with the external flue, is equipped between the outlet flue and external flue
The equally distributed sealing structure of several layers, asbestos packing is filled between the adjacent sealing structure, and the sealing structure includes
Steel plate and right angle frid, the steel plate are vertically mounted on the external flue close to the side of the outlet flue, the trough with straight angle
Plate is vertically mounted on the outlet flue close to the side of the external flue, and the steel plate is matched with right angle frid, the steel
The trough plate that can move freely is installed between plate and right angle frid.
Preferably, the sealing structure can be respectively formed protection to the asbestos packing two sides, avoid institute at least provided with 2 layers
Asbestos packing is stated because abrasion influences sealing effect.
Preferably, one end that the trough plate is matched with steel plate is higher than one end that the trough plate and right angle frid cooperate
10-15cm,
Preferably, several equally distributed floors are equipped on the outside of the outlet flue, smoke can be enhanced by the floor
The structural strength of mouth.
The beneficial effects of the utility model are shown:
1, make outlet flue and outer cigarette receiving by matching trough plate with steel plate, right angle frid respectively in the utility model
It is formed and is flexibly connected between road, make between outlet flue and external flue to can avoid because of the coefficient of expansion there are good thermal expansivity
Occur phenomena such as cracked on gap, outlet flue or external flue between outlet flue caused by difference and external flue, influences
The sealing effect of boiler；
2, it matches with steel plate, right angle frid respectively by trough plate in the utility model and to form once sealing, pass through phase
It is good that asbestos packing between adjacent sealing structure forms secondary seal sealing effect, while trough plate can protect asbestos packing and avoid
Directly washing away for flue gas, can keep being in close contact between asbestos packing and sealing structure, be conducive to improve sealing effect；
3, flute profile board ends are directly taken and are placed on steel plate and right angle frid in the utility model, trough plate disassembling, assembling and replacing letter
Singly, conveniently.
Detailed description of the invention
Fig. 1 is a kind of overall structure diagram of boiler labyrinth-type excluder of the utility model；
Fig. 2 is the partial enlarged view of A in Fig. 1
Fig. 3 is a kind of cross-sectional view of boiler labyrinth-type excluder of the utility model.
In figure: the external flue of 1- outlet flue, 2-, 3- asbestos packing, 4- steel plate, the right angle 5- frid, 6- trough plate, 7- are horizontal

Specific embodiment
In order to facilitate the understanding of those skilled in the art, the utility model will be further described below with reference to the accompanying drawings.
A kind of boiler labyrinth-type excluder as shown in Figs. 1-3 including the outlet flue 1 on boiler and is plugged on described
External flue 2 in outlet flue 1, the outlet flue 1 is interior to be equipped with the crossbeam 7 matched with the external flue 2, the outlet flue
It is equipped with the equally distributed sealing structure of several layers between 1 and external flue 2, is filled out between the adjacent sealing structure filled with asbestos
Material 3, the sealing structure include steel plate 4 and right angle frid 5, and the steel plate 4 is vertically mounted on the external flue 2 close to described
The side of outlet flue 1, the right angle frid 5 are vertically mounted on the outlet flue 1 close to the side of the external flue 2, described
Steel plate 4 is matched with right angle frid 5, and the trough plate 6 that can move freely is equipped between the steel plate 4 and right angle frid 5.
The sealing structure can be respectively formed protection to 3 two sides of asbestos packing, avoid the asbestos at least provided with 2 layers
Filler 3 influences sealing effect because of abrasion；One end that the trough plate 6 is matched with steel plate 4 is than the trough plate 6 and right angle frid
