Abstract
The invention provides an improved muffler structure, which can be used for effectively preventing air current in upper and lower cavities of the muffler from being mixed and ensuring the muffling effect. The improved muffler structure comprises a muffler shell and a muffler core, wherein the muffler core is arranged in the muffler shell; the outer side of the muffler core is provided with a bump; and the muffler shell is partitioned into two cavities. The improved muffler structure is characterized in that: the inner side of the muffler shell is provided with a muffler shell bump which is matched with the bump.
Description
Technical field
The present invention relates to the technical field of pressurized machine component, be specially a kind of improved acoustic wave filter structure.
Background technique
After through the pressurized machine supercharging, in the air that blows out of air outlet of pressure shell, very strong pressure and flow velocity are arranged, during by long pressure shell runner, can produce and scream and noise, cause the pressurized machine job insecurity, undesired vibrations, cause the pressurized machine lost of life, affect engine work, and produce noise, for eliminating this phenomenon, be provided with silencing apparatus, existing silencing apparatus is seen Fig. 1, and it comprises silencing apparatus shell 1 and silencing apparatus core 2, be provided with a projection 3 on the silencing apparatus core, silencing apparatus shell 1 is divided into up and down two cavity 4-1,4-2 installs for the ease of the silencing apparatus core, and silencing apparatus core 2 is usually little than silencing apparatus shell 1, at this moment two cavity 4-1 about, the 4-2 air-flow will be ganged up, and has affected the soundproof effect of silencing apparatus.
Summary of the invention
For the problems referred to above, the invention provides a kind of improved acoustic wave filter structure, can effectively avoid up and down ganging up of cavity air-flow of silencing apparatus, guaranteed soundproof effect.
Its technological scheme is such: a kind of improved acoustic wave filter structure, it comprises silencing apparatus shell and silencing apparatus core, described silencing apparatus core is placed in the described silencing apparatus shell, described silencing apparatus core arranged outside has a projection, described silencing apparatus shell is divided into two cavitys, it is characterized in that: described silencing apparatus shell inboard is provided with the silencing apparatus shell projection that cooperates with described projection.
In the said structure of the present invention, because silencing apparatus shell inboard is provided with the silencing apparatus shell projection that cooperates with projection, effectively cut off up and down two cavitys, avoided up and down ganging up of cavity air-flow of silencing apparatus, guaranteed soundproof effect.
Description of drawings
Fig. 1 is existing acoustic wave filter structure master TV structure figure;
Fig. 2 is the main TV structure figure of acoustic wave filter structure of the present invention;
Fig. 3 is the sectional view of Fig. 2.
Embodiment
See Fig. 2, Fig. 3, a kind of improved acoustic wave filter structure, it comprises silencing apparatus shell 1 and silencing apparatus core 2, silencing apparatus core 2 is placed in the silencing apparatus shell 1, and silencing apparatus core 2 arranged outside have a projection 3, and the silencing apparatus shell is divided into two cavity 4-1,4-2, silencing apparatus shell 1 inboard is provided with the silencing apparatus shell projection 5 corresponding with protruding 3, effectively cut off up and down two cavitys, avoided up and down ganging up of cavity air-flow of silencing apparatus, guaranteed soundproof effect.
