Description
Technical Field
The utility model belongs to the auxiliary assembly field in the pit, concretely relates to pneumatic roofbolter muffler in pit.
Background
A silencer ((Muffler)) is a device that prevents sound from propagating while allowing airflow to pass through, and is an important measure to eliminate 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.
The noise pollution of the pneumatic jumbolter used under the mine is serious, the silencer has obvious reduction effect on various industrial noises, but the existing silencer is large in size, and meanwhile, the installation and disassembly of a machine are inconvenient. In addition, the silencer main body is mainly made of metal such as steel, so that the silencer main body is heavy in weight, inconvenient to install and insufficient in corrosion resistance.
In summary, in order to overcome the structural deficiency of the existing silencer, a silencer with simple structure, small volume, light weight and good effect needs to be designed.
Disclosure of Invention
In view of this, the present invention provides a muffler for a downhole pneumatic jumbolter, …
In order to achieve the purpose, the technical scheme is as follows:
the silencer of the underground pneumatic jumbolter comprises an explosion-proof hose and a silencer, wherein an air inlet at one end of the silencer is connected with the explosion-proof hose, and an air outlet is formed at the other end of the silencer; the silencer comprises a silencing barrel, silencing cotton and a silencing net, wherein the silencing net is arranged inside the silencing barrel, the silencing cotton is filled between the silencing net and the inner wall of the silencing barrel, and the silencing net is a rhombic grid.
Further, the explosion-proof hose is connected with the silencer through threads.
Furthermore, the sound-deadening net is in a rhombic grid shape.
Further, the sound-deadening net can be a corrugated filter net.
The utility model has the advantages that: the utility model discloses simple structure, reasonable in design, it is with low costs, the noise cancelling effect is good, reduces more than 60% than before, also improves constructor's operation environment, and work efficiency also obtains improving.
