Abstract
A built-in cone-shaped muffler device is fit to an axial-flow fan which is a special conduit-type double-impeller axial-flow fan for kitchens, and the structure of the axial-flow fan is not described in detail. The built-in cone-shaped muffler device is characterized in that the device comprises an outer cylinder, a muffler device, more than three brackets and a flange structure component; the muffler device is fixedly connected with the brackets through the outer cylinder; the outer cylinder is fixedly connected with the axial-flow fan through the flange structure; the muffler device adopts a cone-shaped structure; the gradient of the outer part of the muffler device is the same as that of an impeller shaft disc, and the bottom surface thereof is bonded with impellers; superfine glass fiber fabric filler is filled in the muffler device; and a muffler madreporic plate is arranged at the outer part of the muffler device in the position opposite to the impellers. The cone-shaped muffler device is directly mounted at the front end of the impeller shaft disc of the fan, so that the outer space of the fan is not occupied; the cone-shaped streamline design of the whole device plays the role of flow guide, which ensures that airflow can enter smoothly without hindrance; meanwhile, the efficient air intake area is enlarged, and the friction resistance of airflow entering is reduced by more than 60 percent, so that the work efficiency of the fan is improved by 30 percent compared with that of a conventional fan; and the operating noise of the impellers, the motor, the wind speed and the like is directly reduced at the noise source, so that the noise reduction capability is increased by 15 percent compared with a conventional muffler device.
Description
Technical field
The utility model relates to a kind of blower fan silencing equipment, relates in particular to a kind of round silencer of awl that is built in blower fan structure itself.
Background technique
Blower fan is a kind of general machinery equipment, and its using scope is very wide, and the production of every profession and trades such as electric power, mine, machinery, metallurgy, chemical industry all be unable to do without blower fan.The noise of the on-stream generation of blower fan usually becomes influences the misfortune of workers ' health and interference environment source.Particularly be close to the blower fan in living area, the air power noise of its intake grill and the radiation of exhaust outlet institute, the principal element of befouling environment forms public hazards especially, is that Industry Branch is administered one of main object of noise pollution in recent years.For the fan noise pollution control, conventional silencer all adopts outer Placement to be installed in the complete blower front end, and volume is big, it is more to take space outerpace, and the gas current friction resistance that enters is very big, and incoming air area is less, cause the task performance of blower fan integral body to reduce greatly, cause waste.
The model utility content
The purpose of this utility model is to overturn present round structure and rectangular configuration silencing apparatus, and main adaptive existing axial-flow blower provides a kind of built-in awl round silencer.
The utility model achieves the goal by following measure:
The round silencer of built-in awl, adaptive with axial-flow blower, axial-flow blower is the special-purpose bilobed wheel axial-flow blower in a kind of pipe type kitchen, concrete structure is no longer given unnecessary details, it specifically is characterised in that, comprise urceolus, silencer, support and flange arrangement parts, silencer is fixedlyed connected by support with urceolus, number of holders is more than three, and urceolus is fixedlyed connected by flange arrangement with axial-flow blower, and silencer is the awl round structure, the gradient of outside is identical with the impeller reel gradient, bottom surface and impeller are fitted, and the silencing apparatus internal material is a ultra-fine fibre glass cloth stuffing, and outside is the noise elimination perforated plate over against impeller.
The beneficial effects of the utility model are: because the round silencing apparatus of awl is directly installed on draught fan impeller reel front end, do not take the blower fan space outerpace, the round Streamline Design of whole awl, play guide functions, guarantee air-flow without hindrance entering smoothly, enlarged effective incoming air area simultaneously, the surface friction drag that air-flow enters reduces more than 60%, the conventional raising of working efficiency that makes blower fan is more than 30%, make the operational noise of impeller, motor, wind speed etc. just carry out direct noise reduction process in noise source, conventional silencer has promoted 15% noise reduction capability.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Shown embodiment of the present utility model in the accompanying drawing.
The round silencer of built-in awl, adaptive with axial-flow blower, axial-flow blower is the special-purpose bilobed wheel axial-flow blower in a kind of pipe type kitchen, concrete structure is no longer given unnecessary details, it specifically is characterised in that, comprise urceolus 1, silencer 2, support 3 and flange 4 structure members, silencer 2 is fixedlyed connected by support 3 with urceolus 1, support 1 quantity is more than three, and urceolus 1 is fixedlyed connected by flange 4 structures with axial-flow blower, and silencer 2 is a conical structure, the gradient of outside is identical with the impeller reel gradient, bottom surface and impeller are fitted, and silencer 2 internal materials are ultra-fine fibre glass cloth stuffing, and outside is the noise elimination perforated plate over against impeller.
