Description
Technical field
The utility model relates to boiler, specifically a kind of combustion natural gas boiler labyrinth type smoke box hermetically-sealed construction.
Background technology
Condenser boiler utilizes efficient smoke condensing waste heat recovering device to carry out sensible heat in the smoke evacuation of absorption boiler afterbody and steam condense the latent heat discharged, to reach the object of raising boiler thermal output.Along with industrial expansion, improving constantly of scientific and technological level, UTILIZATION OF VESIDUAL HEAT IN to economize energy, improve working conditions, reduce the aspects such as production cost and play a part more and more important, become the indivisible part of industrial production.There is the problem of insulation and seal aspect in traditional plain cylindrical furnace, as when pressure combustion, smoke box encapsulation process is bad in Long-Time Service, is easy to cause smoke box to leak cigarette, finally causes quality accident.
Summary of the invention
The defect of seal aspect is there is in the utility model mainly for existing condenser boiler, invent a kind of combustion natural gas boiler labyrinth type smoke box hermetically-sealed construction, the hermetically-sealed construction of smoke box is improved, adopt concavo-convex step-like snap-in structure, form the space of mazy bending, space and sealant complement each other, block flue gas and directly rush at outlet, effectively guarantee that smoke box seals, and avoids smoke spillage, prevent quality accident.
Above-mentioned technical problem of the present utility model is implemented by the following technical programs: a kind of combustion natural gas boiler labyrinth type smoke box hermetically-sealed construction, comprise smoke box casing, cover the smoke box door-plate of smoke box box opening end, it is characterized in that, the concavo-convex step shape in some rank is arranged to inside the openend of smoke box casing, be called faying face A, simultaneously, the step shape that some rank of being arranged to match with faying face A, the edge of smoke box door-plate are concavo-convex, be called faying face B, then pass through faying face A between smoke box casing and smoke box door-plate, concavo-convex engaging formation between faying face B removably connects, at faying face A, sealant is provided with between faying face B.
As preferably, described faying face A is at least arranged to two rank right angle platform scalariforms.
As preferably, described faying face B is at least arranged to two rank right angle platform scalariforms.
As preferably, described sealant is clamped between faying face A and faying face B, and sealant is near the outer end of faying face A and faying face B.
Due to the existence of sealant, make the space being similar to labyrinth defining bending between faying face A, faying face B, so flue gas needs can closely to export through turning round; Again due to the existence of sealant, block smoke spillage.Generally speaking, space and the sealant of mazy bending complement each other, and the space of bending blocks flue gas and directly rushes at outlet, defines obstruction to smoke spillage, and sealant near outlet, with faying face A and faying face B compact siro spinning technology, avoid flue gas to overflow.
As preferably, have the pressing plate for suppressing smoke box door-plate in the end arranged outside of smoke box casing, pressing plate is connected with smoke box casing, and meanwhile, pressing plate extends to outside smoke box door-plate from smoke box casing, props up smoke box door-plate.
As preferably, curved shape is arranged to by described pressing plate, and one end of pressing plate is connected with smoke box casing; The middle part of pressing plate, has a fastening bolt to be connected to smoke box casing through after pressing plate; The other end of pressing plate extend to smoke box door-plate outside, prop up smoke box door-plate from outside; It not compact siro spinning technology between faying face A and faying face B, that is not tight engaging between smoke box casing and smoke box door-plate, be not fixedly connected with, so need foreign object to locate smoke box door-plate, and the opening and closing controlling smoke box door-plate is flexibly convenient in the setting of pressing plate.
In sum, the utility model compared with prior art tool have the following advantages:
The utility model carries out the hermetically-sealed construction of smoke box, and space and the sealant of mazy bending complement each other, and the space of bending blocks flue gas and directly rushes at outlet, obstruction is defined to smoke spillage, effectively guarantee that smoke box seals, handle smoke box well and leak cigarette problem, can quality accident be prevented.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Number in the figure is: 1, smoke box casing; 11, faying face A; 2, smoke box door-plate; 21, faying face B; 3, sealant; 4, pressing plate.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment 1:
As shown in Figure 1, a kind of combustion natural gas boiler labyrinth type smoke box hermetically-sealed construction, comprise smoke box casing 1, smoke box door-plate 2, smoke box door-plate 2 covers the openend of smoke box casing 1; Be arranged to the right angle step shape that three rank are concavo-convex inside the openend of smoke box casing 1, be called faying face A11; Simultaneously, the right angle step shape that two rank being arranged to match with faying face A11, the edge of smoke box door-plate 2 are concavo-convex, be called faying face B21, then formed between smoke box casing 1 with smoke box door-plate 2 concavo-convex engage removably connect, sealant 3 is provided with between faying face A11, faying face B21, sealant 3 is clamped between faying face A11 and faying face B12, make the space being similar to labyrinth defining bending between faying face A11, faying face B21, and sealant 3 is near the outer end of faying face A11 and faying face B21.
