Description

Double-combination silencer
Technical Field
The utility model relates to a silencing device especially relates to a two combination silencing device.
Background
Silencers are a device that prevents sound transmission while allowing airflow through, and are an important measure for eliminating aerodynamic noise. The silencer is a device for reducing noise, which is arranged on an airflow channel of air power equipment (such as a blower, an air compressor, a boiler exhaust port, a generator, a water pump and other equipment with high noise at an exhaust port) or in an air inlet and exhaust system.
Most of steam silencing devices in the prior art are conventional silencing devices, expected noise reduction effect cannot be achieved in the using process, the noise reduction effect is poor, and when the environmental protection problem is increasingly severe, the phenomena that the environmental protection does not reach the standard and the like are caused frequently because of large noise.
Disclosure of Invention
In view of this, the utility model aims at providing a two combination silencing device, aim at solving the serious problem of noise pollution when steam exhausts.
In order to achieve the purpose, the technical scheme is as follows:
a double-combination silencing device comprises an inner silencing barrel, an outer silencing barrel and a connecting pipe;
one end of the inner silencing barrel is fixedly communicated with the connecting pipe, the other end of the inner silencing barrel is connected with the barrel cover through threads, the connecting pipe is fixedly provided with the connecting cover, one end of the outer silencing barrel is closed, the other end of the outer silencing barrel is open, the other end of the outer silencing barrel is opened, the other end of the outer silencing barrel is connected with the connecting cover through threads, meanwhile, the inner silencing barrel is arranged in the outer silencing barrel, and a plurality of through holes are formed in the barrel walls of the inner silencing barrel and the outer silencing barrel;
silencing cotton is filled between the outer silencing tube and the inner silencing tube, and a silencing cotton pad is attached to the inner wall of the inner silencing tube.
As a further improvement of the present invention, the connecting pipe is provided with a thread at its outer end.
As a further improvement of the utility model, the inner silencing tube is a seamless steel tube with the diameter of 100 mm and 600mm, the outer silencing tube is a seamless steel tube with the diameter of 300 mm and 800mm, and the diameter of the through hole is 5 mm.
The utility model has the advantages that:
1. the utility model has simple structure, reasonable design, small volume, light weight, good effect and low manufacturing cost, and greatly improves the working environment;
2. the outer silencing barrel can be detached, the barrel cover of the inner silencing barrel can be opened, the silencing barrel is convenient to clean and replace silencing cotton and silencing cotton pads, and moreover, the double-layer silencing barrel is adopted, so that the silencing effect is remarkable, the double-layer silencing barrel can be repeatedly utilized, and the service life is prolonged while the operation environment is improved.
