Abstract

The utility model relates to a silencing device adapted for using the combustion engine exhaust system and decreasing the exhaust noise, in particular to a vortex type silencer adapted for the exhaust systems of automobile, motorcycle, tractor, craft, etc. The utility model comprises an air inlet (4), an outer cylinder body (3) and an air outlet (5). An arc baffle (1) is arranged in the interior of the outer cylinder body in interval arrangement, and the outer edge of the baffle (1) is connected with the outer cylinder body (3). The bottom of the baffle (1) is provided with a through hole. A connection fixing piece (2) is connected and fixed between each baffle. Based on the different silencing requests, the arc baffle can adopt the regular circle or the ellipse and the concentric circle or the eccentric circle, and the connection fixing piece can be a hole plate or a solid plate. The silencer of the utility model has greatly improvement on the silencing effect, and the power loss is small. When the air current is stronger, the silencing effect is better.

Description

The vortex type silencing apparatus
Technical field
The utility model relates to a kind of use internal combustion engine exhaust system that is applicable to, reduces the silencer of exhaust sound, is specifically related to a kind of vortex type silencing apparatus that is applicable to vent systems such as automobile, motorcycle, tractor, boats and ships.
Background technique
Engine exhaust noises such as automobile, motorcycle, tractor pollute has at present become big public hazards that influence town environment.Country has formulated the noise reduction standard, and manufacturer also solves an engine exhaust noise reduction difficult problem in active research.Not only power loss is big and existing silencing apparatus is when solving the noise reduction problem, and noise reduction is not ideal.The utility model provide a kind of simple in structure, power loss is little, the effective silencer of eliminating the noise.
Summary of the invention
The utility model according to aerodynamic principle, has adopted arc-shaped partition (the little bowl in the similar no end) technology on the basis of having researched and analysed existing silencing apparatus technology.
Specifically, vortex type silencing apparatus of the present utility model, comprise suction port (4), outer cylinder body (3), air outlet (5), it is characterized in that: inner barrel outside, be arranged at intervals with arc-shaped partition (1), dividing plate (1) outer is connected with outer cylinder body (3), and dividing plate (1) bottom is provided with through hole, is connected and fixed by being connected and fixed part (2) between each dividing plate.
According to different noise elimination requirements, arc-shaped partition can adopt just circle or oval, eccentric or concentric; Be connected and fixed part and can be orifice plate or real plate.
Through experiment, the noise elimination effect improves a lot, and power loss is little, and air-flow is strong more, and the noise elimination effect is good more.
Description of drawings
Accompanying drawing is the sectional view of the utility model silencing apparatus.
(1) is arc-shaped partition (the little bowl in the similar no end); (2) be the part that is connected and fixed of each dividing plate; (3) be outer cylinder body; (4) be suction port (being connected) with motor; (5) be the air outlet.
Embodiment
The utility model mainly adopts arc-shaped partition.After the powerful fluctuation air-flow of discharging from motor enters outer cylinder body (3) from suction port (4), run into arc-shaped partition (1), on arcwall, rotate, form eddy current, with the flexible way sound energy consumption.Behind the same manner noise reduction repeatedly, discharge (5) from the air outlet at last, promptly reaches the purpose of noise elimination noise reduction.

Claims (3)

1, a kind of vortex type silencing apparatus, comprise suction port (4), outer cylinder body (3), air outlet (5), it is characterized in that: inner barrel outside, be arranged at intervals with arc-shaped partition (1), dividing plate (1) outer is connected with outer cylinder body (3), dividing plate (1) bottom is provided with through hole, is connected and fixed by being connected and fixed part (2) between each dividing plate.
2, vortex type silencing apparatus according to claim 1 is characterized in that: arc-shaped partition (1) can be just circle or oval, and is eccentric or concentric.
3, vortex type silencing apparatus according to claim 1 is characterized in that: being connected and fixed part (2) is orifice plate or real plate.
