Abstract
The invention relates to a silencer barrel installation structure of an entrance silencer. According to the silencer barrel installation structure, the upper part of the inner wall of a silencer barrel body is fixedly provided with a upper end ring sealing plate; the lower part of the inner wall of the silencer barrel body is fixedly provided with a lower end ring sealing plate; an inner barrel body is arranged in the silencer barrel body; the inner barrel body is made of orifice plates; excircle upper part of the inner barrel body and incircle part of the upper end ring sealing plate are fixed together, and excircle lower part of the inner barrel body and incircle part of the lower end ring sealing plate are fixed together; and a first silencing screen mesh is arranged between the inner barrel body and the silencer barrel body. The silencer barrel installation structure possesses advantages such as less operation vibration and operation noise, simple and reasonable structure, and stable and firm installation.
Description
Technical field
The present invention relates to a kind of structure of intake silencer, especially a kind of hush pipe mounting structure of intake silencer.
Background technique
At present, on the gas pipeline of access helical-lobe compressor, baffler is not installed, during work, can be produced very large noise, workman's work situation is poor.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide that a kind of operational shock is little, operation noise is little, simple and reasonable for structure, it is stable to install, the hush pipe mounting structure of intake silencer firmly.
According to technological scheme provided by the invention, the hush pipe mounting structure of described intake silencer, inwall upper end portion at baffler cylindrical shell is fixed with top ring shrouding, inwall underpart at baffler cylindrical shell is fixed with lower loop shrouding, in baffler cylindrical shell, be provided with inner barrel, inner barrel is orifice plate, the cylindrical upper end portion of inner barrel and the inner circle of top ring shrouding are fixed, the cylindrical underpart of inner barrel and the inner circle of lower loop shrouding are fixed, and are provided with the first noise reduction silk screen between inner barrel and baffler cylindrical shell.
Inwall upper end portion at inner barrel is fixed with girth sheets, in the inwall underpart of inner barrel, is fixed with lower girth sheets.
Inwall middle part at inner barrel is fixed with support ring, is fixed with bearing rib on support ring.
The present invention has the advantages such as operational shock is little, operation noise is little, simple and reasonable for structure, installation is stable, firm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
The hush pipe mounting structure of this intake silencer, inwall upper end portion at baffler cylindrical shell 1 is fixed with top ring shrouding 2, inwall underpart at baffler cylindrical shell 1 is fixed with lower loop shrouding 3, in baffler cylindrical shell 1, be provided with inner barrel 4, inner barrel 4 is orifice plate, the cylindrical upper end portion of inner barrel 4 and the inner circle of top ring shrouding 2 are fixed, and the cylindrical underpart of inner barrel 8 and the inner circle of lower loop shrouding 3 are fixed, and are provided with the first noise reduction silk screen 5 between inner barrel 8 and baffler cylindrical shell 1.
Inwall upper end portion at inner barrel 4 is fixed with girth sheets 6, in the inwall underpart of inner barrel 4, is fixed with lower girth sheets 7.
Inwall middle part at inner barrel 4 is fixed with support ring 8, is fixed with bearing rib 9 on support ring 8.
Due to the cylindrical upper end portion of inner barrel 4 and the inner circle of top ring shrouding 2, fix, the cylindrical underpart of inner barrel 8 and the inner circle of lower loop shrouding 3 are fixed, and have limited the vibration of inner barrel 4 when work, have avoided generation vibrating noise.
And by bearing rib 9, supported in the middle part of the inwall of inner barrel 4, bearing rib 9 two end part are all fixed with support ring 8, have further limited the vibration of inner barrel 4 when work, have avoided generation vibrating noise.
