Abstract
The utility model provides an improved muffler structure which can enable the fact that airflow of an upper cavity and a lower cavity of a muffler goes up and down to be effectively avoided, and therefore noise abatement effect is guaranteed. The improved muffler structure comprises a muffler shell and a muffler core, wherein the muffler core is placed in the muffler shell, a protrusion is arranged on the outer side of the muffler core, and the muffler is divided into two cavities by the protrusion. The improved muffler structure is characterized in that a muffler shell protrusion which is matched with the protrusion is arranged on the inner side of the muffler shell.
Description
Technical field
The utility model relates to the technical field of pressurized machine component, is 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 utility model provides a kind of improved acoustic wave filter structure, can effectively avoid up and down ganging up of cavity air-flow of silencing apparatus, has 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 utility model, 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.
