Abstract
The present invention provides a kind of curved row's acoustic filter, and described acoustic filter includes exhaustor, upper shell and lower house；Described exhaustor includes some exhaust duct apertures；The horizontally disposed air inlet pipe of described lower house；Described exhaustor is stretched out through upper shell, lower house, is connected with air inlet pipe in lower casing in vitro；When gas enters air inlet pipe, due to air inlet pipe have continuous bending, vertical plane 2 90 bends, the impulsive force of gas gradually decreases, it is possible to reduce noise, invention also reduces manufacturing cost, firm in structure durable.
Description
Technical field
The invention belongs to the deafener apparatus field of Diesel engine, specially a kind of curved row's acoustic filter.
Background technology
Generally simple after the tail gas air inlet expansion air-flow chamber of existing acoustic filter, can so reduce certain making an uproar
Sound, but the control being a lack of on gas impulsive force is reduced, reduce noise pollution, the noise abatement dress in existing minimizing gas impulsive force
Standby expensive, and complex structure, it is easily damaged, use cost is high；It is therefore desirable under the conditions of certain cost, completing to existing
Some acoustic filters are improved.
Content of the invention
The purpose of the present invention is to provide a kind of curved row's acoustic filter for market；Noise can be reduced in gas impulsive force, drop
Low cost.
The technical scheme is that：A kind of curved row's acoustic filter, described acoustic filter include exhaustor, upper shell and lower casing
Body；Described exhaustor includes some exhaust duct apertures；Described exhaustor is stretched out through upper shell, lower house, external in lower casing
It is connected with air inlet pipe；Described air inlet pipe is the bend pipe of continuous bending 2 90, and 2 folding surfaces are vertical；Described air inlet pipe
Parallel with exhaustor gas outlet plane.
Preferably, dividing plate is fixed with the middle of upper shell and lower house；Described dividing plate is provided with air-vent, and peripherally point
Weldering is connected in acoustic filter；Solid sprue is provided with the middle part of described exhaustor, and exhaust duct aperture is divided into upper and lower two part；Air-flow leads to
After crossing air inlet pipe, discharged by the air vent of exhaustor after the air-vent of dividing plate and exhaust duct aperture shunting, noise reduction.
Preferably, there is at the boil on the nape opposite the mouth of the upper shell and lower house flange, the flange of the flange and lower house of upper shell
Connected by rolling.
Preferably, under the air vent of described exhaustor, it is provided with and is covered in the external anti-scald cover of upper shell and lower casing.
Preferably, described anti-scald cover is provided with circular, square or oval louvre.
Preferably, the convex portion for fixed and sealing exhaust pipe and acoustic filter is provided with aerofluxuss tube body, and described is convex
Portion is pressed on upper shell.
Preferably, described convex portion aerofluxuss tube body is integrally formed, through swollen type and upper lower cavity die extruding aftershaping.
The invention has the beneficial effects as follows：A kind of Anti-burn silencing device, in gas impulsive force aspect can reduce noise, reduce
Manufacturing cost, firm in structure durable.

Top views of the Fig. 5 for anti-scald cover；
In figure：1 is exhaustor, and 2 is upper shell, and 3 is dividing plate, and 4 is lower house, and 5 is air inlet pipe, and 6 is anti-scald cover.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Such as Fig. 1 and Fig. 2, a kind of curved row's acoustic filter, described acoustic filter include exhaustor 1, upper shell 2 and lower house 4；Institute
The exhaustor 1 that states includes some exhaust duct apertures；Described exhaustor 1 is stretched out through upper shell 2, lower house 4, outside lower house 4
It is connected with air inlet pipe 5；Described air inlet pipe 5 is the bend pipe of continuous bending 2 90, and 2 folding surfaces are vertical；Described air inlet
Pipe 5 is parallel with 1 gas outlet plane of exhaustor.When gas enters air inlet pipe 5, due to have continuous bending, the 2 of vertical plane
Individual 90 bend, the impulsive force of gas are gradually decreased, it is possible to reducing noise.
Such as Fig. 3, in the middle of upper shell 2 and lower house 4, it is fixed with dividing plate 3；Described dividing plate 3 is provided with air-vent, and along week
Edge point weldering is connected in acoustic filter；Solid sprue is provided with the middle part of described exhaustor 1, exhaust duct aperture is divided into upper and lower two part；
Air-flow is discharged by the air vent of exhaustor 1 after air inlet pipe after the air-vent of dividing plate 3 and exhaust duct aperture shunting, noise reduction.
The flange at the boil on the nape opposite the mouth of the upper shell 2 and lower house 4 with flange, the flange of upper shell 2 and lower house 4 passes through
Rolling connection.
Such as Fig. 4 and Fig. 5, under the air vent of described exhaustor 1, be provided be covered in anti-scald outside upper shell 2 and lower house 4
Cover 6.
Described anti-scald cover 6 is provided with circular, square or oval louvre.
The convex portion for fixed and sealing exhaust pipe 1 and acoustic filter is provided with aerofluxuss tube body, and described convex portion is pressed
On upper shell 2.
