The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model is to reduce to produce tempering phenomenon after wind enters the boiler exhaust gas cover.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of boiler exhaust gas cover, be arranged on boiler, and comprise outer cover and be arranged on outer cover interior nozzle for flow dismounting plate, nozzle for flow dismounting plate support, deflector; Described outer cover is shaped as trapezoidal, be provided with a chimney at trapezoidal end face, described deflector is an arc, below and two ends that described arc is arranged on chimney are connected with the both sides, front and back of outer cover, and the distance of the top of described arc and outer cover right plate is greater than the bottom of arc and the distance of outer cover right plate; Described nozzle for flow dismounting plate all is connected with the both sides, front and back of outer cover with left side and two ends that the nozzle for flow dismounting plate support all is arranged on deflector, this nozzle for flow dismounting plate also is arranged on the upside of nozzle for flow dismounting plate support, described nozzle for flow dismounting plate is a swash plate, the distance of the top of described swash plate and outer cover right plate is greater than the bottom of nozzle for flow dismounting plate and the distance of outer cover right plate, described nozzle for flow dismounting plate is divided into outer cover the first flow region and second flow region of mutual circulation, described the first flow region is communicated with boiler, and described the second flow region leads to the outside.
Described nozzle for flow dismounting plate and horizontal angle of inclination are 30 °.
Described deflector is arranged in the second flow region.
(3) beneficial effect
Boiler exhaust gas cover of the present utility model, by being set, nozzle for flow dismounting plate and deflector the external world can be carried out water conservancy diversion from a part of wind that chimney enters, be discharged to the external world by the second flow region, thereby reduced wind and entered the interior wind-force of boiler, reduced the power that in stove, fire refluxes, thereby reduced the injury to boiler fitting, improved the service life of boiler integral body, strengthened again security.
Description of drawings
Fig. 1 is the stereogram of boiler exhaust gas cover of the present utility model;
Fig. 2 is that boiler exhaust gas cover of the present utility model is arranged on the structural representation on boiler;
In figure, 1 is that outer cover, 2 is that deflector, 3 is that nozzle for flow dismounting plate, 4 is that nozzle for flow dismounting plate support, 5 is that chimney, 6 is that the first flow region, 7 is that the second flow region, 8 is boiler.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
a kind of boiler exhaust gas cover as depicted in figs. 1 and 2 is arranged on boiler, comprises outer cover 1 and is arranged on outer cover 1 interior nozzle for flow dismounting plate 3, nozzle for flow dismounting plate support 4, deflector 2, described outer cover 1 is shaped as trapezoidal, be provided with a chimney 5 at trapezoidal end face, described deflector 2 is an arc, below and two ends that described arc is arranged on chimney 5 are connected with the both sides, front and back of outer cover 1, and the distance of the top of described arc and outer cover 1 right plate is greater than the bottom of arc and the distance of outer cover right plate 1, by this structure can be with a part of wind of coming in from chimney 5 by arc discharged to the external world, described nozzle for flow dismounting plate 3 all is connected with the both sides, front and back of outer cover 1 with left side and two ends that nozzle for flow dismounting plate support 4 all is arranged on deflector 2, this nozzle for flow dismounting plate 3 also is arranged on the upside of nozzle for flow dismounting plate support 4, described nozzle for flow dismounting plate 3 is a swash plate, the distance of the top of described swash plate and outer cover 1 right plate is greater than the bottom of nozzle for flow dismounting plate 3 and the distance of outer cover 1 right plate, described nozzle for flow dismounting plate 3 is divided into outer cover 1 the first flow region 6 and second flow region 7 of mutual circulation, described the first flow region 6 is communicated with boiler 8, described the second flow region 7 leads to the outside.Also a part of wind of coming in from chimney 5 can be passed through arc side by side to the external world by this structure.Reduce the wind-force of the first flow region 6, reduce the pressure that wind refluxes, thereby reduce the injury to boiler fitting, in the service life of having improved boiler integral body, strengthened again security.
