Abstract
An unpowered efficient smoke-exhausting funnel cap comprises a bottom board (1), a wind shield (2), a guide segment (3) and a cap cover (4). The cylindrical or cone-frustum-shaped wind shield is arranged on the circular bottom board (1). Drain pipes (5) are distributed on the bottom board (1). The conical guide segment (3) is connected with an exhaust duct (6). The cap cover (4) is supported by cap columns (7). The lower portion of the cap cover (4) is arc-shaped, the upper portion of the cap cover (4) is conical, and the upper portion and the lower portion are connected through a screw. By the unpowered efficient smoke-exhausting funnel cap, exhaust efficiency of the building exhaust duct is improved greatly, and the problems that backflows occur in the duct, smoke exhausting efficiency is low and the like are solved. The funnel cap among series of products is made in factories by forms, shape and size of the funnel cap are both guaranteed, and construction quality and using effect are guaranteed.
Description
Technical field
The utility model relates to the building smoke removal facility, and concrete is a kind of passive highly effective smoke discharging blast cap.
Background technology:
Building blow-out shaft blast cap mainly cooperates building kitchen, washroom exhaust gas flue to use, and can effectively improve the smoke evacuation and the drafting efficiency of exhaust gas flue through the installation of blast cap, prevents that pouring in down a chimney from appearring in exhaust gas flue and prevents that rainwater from getting into exhaust gas flue phenomenon etc.But because of blast cap is installed in building high building roof; Often let the people ignore its existence and importance thereof easily; Therefore many blast cap products that only can satisfy anti-rainwater infiltration function occurred, and be used in a large number in the building operations, such product does not only reach and improves smoke evacuation, drafting efficiency; Also can hinder the discharge of flue gas nature, lose the blast cap most important function.
Weather shield is arranged at existing building exhaust gas flue vertical shaft top; Steam vent is arranged all around, when not having air to flow smoke discharging effect still can, it is smooth even the phenomenon that flue gas pours in down a chimney takes place when air flows, can to form smoke evacuation; Its construction is that build by laying bricks or stones at the scene, thereby can't form quality certification system.The windproof blast cap that keeps off the rain that the squarely made is also arranged, because its simple structure only has certain effect in specific direction, it is not smooth can to form smoke evacuation in other directions yet.
Summary of the invention:The purpose of the utility model is to provide a kind of passive highly effective smoke discharging blast cap, and this blast cap has improved the smoke exhaust efficiency of building exhaust gas flue greatly, has fundamentally solved flue and has occurred pouring in down a chimney and problems such as smoke discharging efficient is low.This blast cap is designed with series of products, uses Mold Making in factory, and geomery is all guaranteed, has also just guaranteed construction quality and result of use.
The formation of the utility model: a kind of passive highly effective smoke discharging blast cap, comprise base plate, windshield, diversion section and blast cap lid, it is characterized in that; Be cylindrical windshield on the circular bottom plate, be distributed with tapping pipe on the base plate, the taper diversion section is connected with exhaust gas flue; The blast cap post supports the blast cap lid; Blast cap lid bottom is curved, and it is conical that top is, and top and the bottom connect through screw rod.
Described windshield can also be a circular platform type.
Compared with prior art; The utility model makes full use of aerodynamics and fluid mechanics principle; Through columniform windshield and the design of conical blast cap lid, make blast cap under the situation that has the gentle breeze air to flow, the opposite zone of flowing at air forms negative pressuren zone; Thereby flue gas is extracted out the efficient of increased the smoke evacuation of vertical shaft exhaust gas flue, ventilating rapidly.And speed air flow is fast more, and smoke discharging efficient is high more.This blast cap is used Mold Making in factory, and fabricating quality, appearance and size all have the technical quality management to ensure.Simultaneously, this blast cap need not to use high-grade energy to drive, and meets the industrial policy of national energy-saving and emission-reduction.
Description of drawings:
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the vertical view of Fig. 1,
Fig. 3 is another embodiment circular platform type windshield blast cap sketch map.
Among the figure: 1, base plate, 2, windshield, 3, diversion section, 4, the blast cap lid, 5, tapping pipe, 6, exhaust gas flue, 7, the blast cap post.
The specific embodiment:According to accompanying drawing and embodiment the passive highly effective smoke discharging blast cap of the utility model is further described below.
As shown in the figure, a kind of passive highly effective smoke discharging blast cap comprises base plate 1, windshield 2, diversion section 3 and blast cap lid 4; It is characterized in that, be cylindrical windshield 2 on the circular bottom plate 1, is distributed with tapping pipe 5 on the base plate 1; Taper diversion section 3 is connected with exhaust gas flue 6, and blast cap post 7 supports blast cap lid 4, and it is curved that blast cap covers 4 bottoms; Top is tapered, and top and the bottom connect through screw rod.
Described base plate: mainly bear the whole total amount of blast cap, and with windshield, diversion section, prefabricated blast cap post, spilled water hole is installed and fix;
Described windshield is cylindrical, and according to fluid mechanics principle, circular windshield design can make full use of the air draught of any direction in roof, through the method for partial compression air, forms available air force.And speed air flow is fast more, and smoke discharging efficient is high more.
Described windshield can also be a circular platform type.
Described diversion section is the taper diversion section: the design of bell-mouthed diversion section with flue gas according to diffusion way gradually to around diffusion, to reduce the diffusional resistance loss.
Described blast cap lid is for conical, air draught along guiding on the frontal arc alignment, and formed the air-negative-pressure district at the back at the circular cone dish, thereby improve the drag characteristic of blast cap, improves the smoke discharging efficient of smoke discharging hoistway.
The utility model has improved the smoke exhaust efficiency of building exhaust gas flue greatly, has fundamentally solved flue and has occurred pouring in down a chimney and problems such as smoke discharging efficient is low.This blast cap is designed with series of products, uses Mold Making in factory, and geomery is all guaranteed, has also just guaranteed construction quality and result of use.
Claims (2)
1. a passive highly effective smoke discharging blast cap comprises base plate (1), windshield (2), diversion section (3) and blast cap lid (4), it is characterized in that: be cylindrical windshield (2) on the circular bottom plate (1); Be distributed with tapping pipe (5) on the base plate (1); Taper diversion section (3) is connected with exhaust gas flue (6), and blast cap post (7) supports blast cap lid (4), and blast cap lid (4) bottom is curved; Top is tapered, and top and the bottom connect through screw rod.
