Abstract

The invention provides a kind of baffler, interior, between urceolus, porous packing is set, the gap between inner/outer tube and porous packing can be utilized to absorb a part of noise, and the cavity volume outwardly arranged on urceolus, because this cavity volume is large compared with the size of the circle of urceolus and be multiple setting that is spaced apart, therefore absorption part noise that can be interim, absorbed by next one cavity volume outwardly again after acoustic noise reducing, the grid arranged at inner core is provided with dispersing tablet, dispersing tablet is provided with the sound-absorption layer of the material formation with sound-absorbing effect, noise is absorbed.Because grid is also multiple and separation arrangement, also can plays interim noise-reduction, progressively by noise absorbent, thus reach good erasure effect.

Description

A kind of baffler
Technical field
The present invention relates to a kind of baffler, belong to silencer field.
Background technique
Noise being produced in exhaust ports, baffler can be installed for eliminating these noises.Baffler contains outer tube and interior pipe, and baffler is generally made up of outer tube and interior pipe, and outer tube upper end is connected with relevant device relief opening.During work, the noise entered the gas of outer tube from outer tube upper end enters interior pipe, is absorbed, then carry out sound insulation by the spacing between interior pipe and outer tube by the tube wall of interior pipe, realizes the object reducing noise.But find in working practice, erasure effect is poor.
In view of this special proposition the present invention.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of baffler, overcomes the problem of existing baffler erasure effect difference.
The invention provides following technological scheme:
A kind of baffler, comprise inner core and urceolus, urceolus is distributed with cavity volume outwardly, inner core is socketed in urceolus, is filled with porous packing between inner core and urceolus, and inner core inside is provided with the grid be made up of top slat iron and perpendicular skeleton, the dividing plate of grid is provided with dispersing tablet, dispersing tablet is V-shaped to be arranged on perpendicular skeleton, and the V-arrangement inclined-plane of dispersing tablet is identical with airflow direction, leaves gap between the end of dispersing tablet and top slat iron.
The cavity volume outwardly that urceolus distributes is that interval is arranged, and arranges along urceolus central axial direction.
Further, the cavity volume outwardly on urceolus is circular, is concentric circle with the circle of urceolus.
Further, the cavity volume outwardly on urceolus is square, and square each length of side is greater than the diameter of a circle of urceolus, and the center of cavity volume is consistent with the round center of urceolus.
Further, the grid in inner core has multiple, is separated arrangement along inner core central axis.
A kind of baffler of the present invention, between inner/outer tube, porous packing is set, the gap between inner/outer tube and porous packing can be utilized to absorb a part of noise, and the cavity volume outwardly arranged on urceolus, because this cavity volume is large compared with the size of the circle of urceolus and be multiple setting that is spaced apart, therefore absorption part noise that can be interim, absorbed by next one cavity volume outwardly again after acoustic noise reducing, the grid arranged at inner core is provided with dispersing tablet, dispersing tablet is provided with the sound-absorption layer of the material formation with sound-absorbing effect, noise is absorbed.Because grid is also multiple and separation arrangement, also can plays interim noise-reduction, progressively by noise absorbent, thus reach good erasure effect.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and forms a part for specification, together with embodiments of the present invention for explaining the present invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of baffler of the present invention.
Fig. 2 is the schematic side view of a kind of baffler of the present invention.
1, urceolus 2, inner core 3, cavity volume 4, top slat iron 5, perpendicular skeleton 6, dispersing tablet 7, porous packing.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of baffler, comprise inner core 2 and urceolus 1, urceolus 1 is distributed with cavity volume 3 outwardly, inner core 2 is socketed in urceolus 1, porous packing 7 is filled with between inner core and urceolus, inner core inside is provided with the grid be made up of top slat iron 4 and perpendicular skeleton 5, and the dividing plate of grid is provided with dispersing tablet 6, dispersing tablet is V-shaped to be arranged on perpendicular skeleton, the V-arrangement inclined-plane of dispersing tablet is identical with airflow direction, leaves gap between the upper and lower end parts of dispersing tablet and top slat iron.Grid in inner core has multiple, and the central axis along inner core 2 is separated arrangement.
The cavity volume outwardly that urceolus distributes is that interval is arranged, and arranges along urceolus central axial direction.
In the present embodiment, the cavity volume 3 outwardly on urceolus 1 is square, and square each length of side is greater than the diameter of a circle of urceolus, and the center of cavity volume is consistent with the round center of urceolus.
In other facility examples, the cavity volume outwardly on urceolus 1 is circular, is concentric circle with the circle of urceolus 1.
A kind of baffler of the present invention, interior, porous packing 7 is set between urceolus, in can utilizing, gap between urceolus and porous packing 7 absorb a part of noise, and the cavity volume 3 outwardly arranged on urceolus 1, because this cavity volume is large compared with the size of the circle of urceolus and be multiple setting that is spaced apart, therefore absorption part noise that can be interim, absorbed by next one cavity volume outwardly again after acoustic noise reducing, the grid arranged in inner core 2 is provided with dispersing tablet, dispersing tablet is provided with the sound-absorption layer of the material formation with sound-absorbing effect, noise is absorbed.Because grid is also multiple and separation arrangement, also can plays interim noise-reduction, progressively by noise absorbent, thus reach good erasure effect.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
