Abstract
The invention discloses a silencer for automobile engine exhaust, which comprises a barrel body, wherein a cone end is formed at the front end of the barrel body; the barrel body is provided with a plurality of partition plates from the cone end to the tail end sequentially, and is divided into a plurality of silencing cavities by the partition plates; a communicating pipe communicating the silencing cavities is arranged in the centers of the partition plates; radially formed first silencing holes are formed in the outer wall of the communicating pipe; conical barrels are arranged in the silencing cavities between every two adjacent partition plates; the cone ends of the conical barrels face towards the cone ends of the barrel body; and second silencing holes formed along the radial direction of the barrel body at intervals are formed in the conical barrels. The silencer is novel in structural design; a part of gas directly enters from the communicating pipe or penetrates through the various silencing cavities, and a part of gas directly penetrates through the various partition plates axially, and then radially flows along barrel walls of the conical barrels in the various silencing cavities, so that the noise can reduced effectively; the silencing effect is good; and the manufacturing cost is low.
Description
Technical field
The present invention relates to baffler, particularly relate to a kind of automobile engine to exhaust baffler.
Background technique
The device of the reduction noise on the air-flow path that silencing apparatus is mounted in air powered equipment or in inlet and exhaust system.The noise that the periodic pressure that automobile engine to exhaust door periodically opens and closes and produces excites is part main in exhaust noise, and the general method reducing exhaust noise arranges silencing apparatus on the relief opening of motor.
The dissipative muffler that automobile primary in the market will be applied is mainly better to high frequency noise treatment effect, but actual manufacturing cost is also relatively high, and working life is short, and process noise result is poor.
Summary of the invention
In order to make up prior art problem, the object of this invention is to provide a kind of automobile engine to exhaust baffler, can car noise be effectively reduced, improve erasure effect.
Technological scheme of the present invention is as follows:
Automobile engine to exhaust baffler, comprise the cylindrical shell that front end is cone end, it is characterized in that: described cylindrical shell is interval with multiple dividing plate from cone end successively to end, cylindrical shell is divided into multiple silencing cavity by multiple dividing plate, multiple dividing plate centers are provided with the connecting tube of the multiple silencing cavity of UNICOM, the outer wall of connecting tube is provided with radial the first bloop arranged, conically shaped is provided with in silencing cavity between two wherein adjacent dividing plates, the cone end of conically shaped, towards the cone end of cylindrical shell, conically shaped is equipped with along spaced second bloop of cylindrical shell radial direction.
Described automobile engine to exhaust baffler, is characterized in that: the first bloop on described connecting tube is uniformly distributed.
Described automobile engine to exhaust baffler, is characterized in that: described multiple dividing plates are resistant to elevated temperatures mesh plate, and the mesh of mesh plate is axially arranged, and the mesh density of multiple dividing plate holds a left side to diminish gradually from the cone of cylindrical shell.
Described automobile engine to exhaust baffler, is characterized in that: the on described conically shaped second radial bloop density holds a left side to diminish gradually from the cone of cylindrical shell.
Advantage of the present invention is:
Novel in structural design of the present invention, a gas part directly to enter connecting tube or through each silencing cavity, a part of gas directly from each dividing plate axially across, barrel Radial Flow again along conically shaped in each silencing cavity, effectively can reduce noise, good muffling effect, cheap for manufacturing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
See accompanying drawing:
Automobile engine to exhaust baffler, comprise the cylindrical shell 1 that front end is cone end, cylindrical shell 1 is interval with multiple dividing plate 2 from cone end successively to end, cylindrical shell is divided into multiple silencing cavity 3 by multiple dividing plate 2, multiple dividing plate 2 centers are provided with the connecting tube 4 of the multiple silencing cavity of UNICOM, the outer wall of connecting tube 4 is provided with radial the first bloop 5 arranged, conically shaped 6 is provided with in silencing cavity between two wherein adjacent dividing plates, the cone end of conically shaped 6, towards the cone end of cylindrical shell, conically shaped 6 is equipped with along spaced second bloop 7 of cylindrical shell radial direction.
The first bloop 5 on connecting tube 4 is uniformly distributed.
Multiple dividing plate 2 is resistant to elevated temperatures mesh plate, and the mesh of mesh plate is axially arranged, and the mesh density of multiple dividing plate holds a left side to diminish gradually from the cone of cylindrical shell.
On conically shaped 6 second radial bloop 7 density holds a left side to diminish gradually from the cone of cylindrical shell 1.
After the present invention's installation in the course of the work, a gas part is directly from entering connecting tube 4 or passing each silencing cavity 3, a part gas directly from each dividing plate axially across, barrel Radial Flow again along conically shaped 6 in each silencing cavity 3, gas forms certain convection current in each silencing cavity 3, thus the noise that the periodic pressure reducing engine exhaust port periodically to open and close and produce excites.
