Abstract
The utility model relates to a silencer, in particular to a throttling pressure reduction type silencer for a blower. According to the throttling pressure reduction type silencer, the technical problems that the silencer for the blower is short in service cycle, easy to damage and the like are solved. The throttling pressure reduction type silencer comprises a casing, wherein a core body is arranged in the casing; a core body structurally comprises a throttling pressure reduction plate in a three-vane shape and a circular throttling pressure reduction plate which are adjacent and are serially connected through a fixed rod; the projection of the throttling pressure reduction plate in a three-vane shape in the axial direction is fully-closed circular; and slicing holes are distributed in the throttling pressure reduction plate in a three-vane shape and the circular throttling pressure reduction plate. According to the throttling pressure reduction type silencer disclosed by the utility model, noise generated by the blower is reduced without influencing gas emission, and thereby the difficult problem that ambient noise exceeds standard is solved.
Description
Technical field
The utility model relates to a kind of silencing apparatus, is specially a kind of blower expenditure and pressure formula baffler.
Background technique
Silencing apparatus is a kind of when allowing air communication to cross, and can stop or weaken the device that acoustic energy is outwards propagated again effectively.It is mainly used in the noise control of the inlet and outlet pipeline or the ventilation duct of machinery.At present in the design of baffler, most of producers all design and produce according to the experience of oneself, and technological secret relatively again.The silencing apparatus type is a lot, mainly contains following three types by its principle of noise reduction: dissipative muffler, reactive muffler and complex muffler.
What originally the used baffler of blower adopted is hole tube coupling streaming noise reduction mode, but the selection of material is thin excessively, and life cycle is shorter, and the internal holes pipe is often blown brokenly by air-flow, influences erasure effect.
Summary of the invention
The utility model is short with the silencing apparatus life cycle in order to solve blower, and technical problems such as easy breakage provide a kind of blower expenditure and pressure formula baffler.
The utility model is realized that by following technological scheme a kind of blower expenditure and pressure formula baffler comprises housing, is provided with core body in the housing; Core comprises the throttling decompression board of three blade-shaped, circular throttling decompression board; The throttling decompression board of three blade-shaped is adjacent with circular throttling decompression board to be connect side by side and through the fixing rod polyphone; The throttling decompression board of three blade-shaped is totally-enclosed circle at axis projection, is distributed with sound attenuation hole on the throttling decompression board of described three blade-shaped and the circular throttling decompression board.
After the noise air-flow gets into from housing one end like this,, can the noise that blower produces be reduced, do not influence gaseous emission again, thereby solve the difficult problem that ambient noise exceeds standard through the throttling hypotensive effect of some throttling decompression boards and the effect of aperture noise reduction.
