Abstract
The invention discloses an anti-impact silencer. The anti-impact silencer comprises a first silencing barrel and a second silencing barrel. The second silencing barrel is concentrically arranged in the first silencing barrel. A third silencing barrel extending to the outer portion of the first silencing barrel is arranged at the tail end of the second silencing barrel. A spring is arranged in the third silencing barrel. A conical hole is formed in the tail end of the second silencing barrel. A conical table corresponding to the conical hole is arranged at the tail end of the spring. The anti-impact silencer is connected to the exhaust end of a device through a gas inlet connection flange, and exhausting is conducted through the first silencing barrel and the second silencing barrel at ordinary times so that noise can be reduced; and when gas flow suddenly increases to form impact, the conical table bears force and gradually disengages from the conical hole so that the third silencing barrel can communicate with the second silencing barrel, the gas impact resistant performance is improved, and the noise generated during gas impact is further reduced.
Description
Technical field
The present invention relates to silencing apparatus field, particularly relate to a kind of protecting against shock acoustic filter.
Background technology
Equipment component adopts compression air to be driven, and the compression air of air compressor and other gas equipments easily produces noise in the process of discharge.
In order to reduce the noise of equipment aerofluxus, need to install corresponding acoustic filter in gas outlet, differentiation air-flow, reduce the noise that air-flow produces in discharge process, but the discharge of gas is not uniform, be often the intermittent discharge with certain impact, common acoustic filter is when experience has impact air-flow, it is difficult to process in time, affects the smooth discharge of gas, even add noise.
Summary of the invention
It is an object of the invention to provide a kind of protecting against shock acoustic filter, resist the impact of gas, reduce noise when impacting.
For reaching this purpose, the present invention by the following technical solutions:
A kind of protecting against shock acoustic filter, including: the first silencing pot and the second silencing pot, described second silencing pot is arranged concentrically in the first silencing pot, the end of described second silencing pot is provided with the 3rd silencing pot extended to outside the first silencing pot, it is provided with a spring in described 3rd silencing pot, the end of described second silencing pot is provided with a bellmouth, and the end of described spring is provided with a taper platform corresponding with bellmouth.
Wherein, the front end of described first silencing pot is provided with a connector drum, and the front end of described connector drum is provided with an air inlet adpting flange.
Wherein, the barrel of described first silencing pot, the second silencing pot and the 3rd silencing pot has been respectively adopted muffler plate, and described muffler plate includes two-layer microwell plate respectively, is provided with noise reduction layer between described two-layer microwell plate.
Wherein, described noise reduction layer is non-woven fabrics or glass cotton.
Wherein, described microwell plate is densely covered with outgassing micropore.
Wherein, described second silencing pot is provided with several gas port.
Beneficial effects of the present invention: a kind of protecting against shock acoustic filter, air inlet adpting flange is utilized to be connected to the exhaust end of equipment, it is exhausted by the first silencing pot and the second silencing pot at ordinary times, reduce noise, and air-flow is when strengthening suddenly and form impact, taper platform stress and progressively disengage bellmouth so that the 3rd silencing pot and the connection of the second silencing pot, improve the performance that opposing gas impacts, reduce noise when gas impacts further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Technical scheme is further illustrated below in conjunction with Fig. 1 and by specific embodiment.
A kind of protecting against shock acoustic filter, including: the first silencing pot 1 and the second silencing pot 2, described second silencing pot 2 is arranged concentrically in the first silencing pot 1, is weldingly connected by gripper shoe 21 between the cylindrical of the first silencing pot 1 inwall and the second silencing pot 2, sound construction.
The end of described second silencing pot 2 is provided with the 3rd silencing pot 3 extended to outside the first silencing pot 1, it is provided with a spring 32 in described 3rd silencing pot 3, the end of described second silencing pot 2 is provided with a bellmouth 23, and the end of described spring 32 is provided with a taper platform 4 corresponding with bellmouth 23.When air-flow strengthens suddenly and forms impact, taper platform 4 stress and progressively disengage bellmouth 23 so that the 3rd silencing pot 3 connects with the second silencing pot 2, improves the performance that opposing gas impacts, and reduces further noise when gas impacts.
In the present embodiment, the front end of described first silencing pot 1 is provided with a connector drum 5, and the front end of described connector drum 5 is provided with an air inlet adpting flange 6, utilizes air inlet adpting flange 6 to be connected with outside exhaust equipment.
In the present embodiment, the barrel of described first silencing pot the 1, second silencing pot 2 and the 3rd silencing pot 3 has been respectively adopted muffler plate, and described muffler plate includes two-layer microwell plate respectively, is provided with noise reduction layer 31 between described two-layer microwell plate, composite construction, it is easier to reduce noise when gas flows through.
In the present embodiment, described noise reduction layer 31 is non-woven fabrics or glass cotton, and many hollow structures, noise when air-flow passes through is little.
In the present embodiment, described microwell plate being densely covered with outgassing micropore, the diameter of outgassing micropore is little, it is possible to differentiation air-flow, reduces the noise of aerofluxus further.
In the present embodiment, described second silencing pot 2 being provided with several gas port 22 so that the portion gas in the second silencing pot 2 flows directly into the first silencing pot 1, increase the treatment effeciency of air-flow, work efficiency is high, is conducive to the densification of structure, reduces cost.
Above content is only presently preferred embodiments of the present invention, for those of ordinary skill in the art, according to the thought of the present invention, all will change in specific embodiments and applications, and this specification content should not be construed as limitation of the present invention.
