Description

Technical Field

[0001] The utility model relates to the technical field of silencing equipment, and particularly relates to a muffler assembly. Background Art

[0002] High-temperature and high-pressure gases are often used in fields such as petroleum and chemical industries. During the emission process of their waste gases, noise is inevitably generated. Without a silencing device or with an unsatisfactory silencing effect, this kind of waste gas will seriously affect on-site operations. Moreover, during the operation of the equipment, a large amount of waste gas is usually generated. It is rather troublesome to replace the components of an ordinary muffler assembly, and the impurities generated inside cannot be cleaned thoroughly. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and propose to design a muffler assembly that facilitates the repair and replacement of the components of the muffler assembly and the cleaning of internal impurities.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] A muffler assembly includes:

[0006] An assembly housing, with an intake pipe provided at the bottom, and gas enters through the intake pipe;

[0007] Sound-absorbing cotton, closely attached to the inner surface of the assembly housing,

[0008] Muffler pipes, evenly arranged inside the assembly housing, with their lower parts connected to a gas distribution plate and their upper parts fixed to the assembly housing through a fixing plate, and the gas distribution plate is installed inside the assembly housing;

[0009] A drain ball valve, provided at the bottom of the assembly housing for facilitating drainage;

[0010] An assembly support, installed at the bottom of the assembly housing.

[0011] For the above technical solution, the assembly housing is installed on the assembly support, which facilitates the operation of the bottom of the assembly housing, such as the installation and repair of the drain ball valve and the intake pipe. In addition, the impurities inside the assembly housing can be discharged through the drain ball valve; the overall structural design facilitates the disassembly and replacement of the muffler pipes.

[0012] Further, an exhaust flange is provided at the top of the assembly housing, and other pipelines can be externally connected to the exhaust flange according to actual needs.

[0013] Further, the gas distribution plate is integrally welded to the assembly housing.

[0014] Further, the sound-absorbing cotton is fixed to the assembly housing by screws.

[0015] Further, the lower part of the assembly housing is connected to the assembly support by bolts.

[0016] Further, the assembly housing is of a circular structure.

[0017] The technical effects of the present utility model:

[0018] Compared with the prior art, a muffler assembly of the present utility model facilitates the repair and replacement of the components of the muffler assembly and the cleaning of internal impurities, can meet the muffling requirements when discharging high-pressure, high-temperature and large-volume gases, reduce noise pollution, and improve the working conditions at the operation site.

[0021] In the figure, 1, assembly housing; 2, assembly support; 3, intake pipe; 4, sound-absorbing cotton; 5, fixed plate; 6, muffler pipe; 7, air distribution plate; 8, sewage ball valve; 9, exhaust flange. Specific embodiments

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the specification.

[0023] Embodiment 1:

[0024] As Figure 1 shown, a muffler assembly involved in this embodiment includes an assembly housing 1, an assembly support 2, an intake pipe 3, sound-absorbing cotton 4, a fixed plate 5, a muffler pipe 6, an air distribution plate 7, a sewage ball valve 8 and an exhaust flange 9.

[0025] The intake pipe 3 of the muffler assembly is below the assembly housing 1 and is welded to the assembly housing 1 as a whole. The port of the intake pipe 3 is connected by a flange, which ensures airtightness and is convenient for installation. The pipeline for discharging gas is connected to the intake pipe 3 and then enters the muffler assembly.

[0026] The lower part of the assembly housing 1 is connected to the assembly support 2 by bolts, which is convenient for disassembling and replacing the muffler pipe 6 inside; the assembly housing 1 is of a circular structure, and an air distribution plate 7, a muffler pipe 6, a fixed plate 5, sound-absorbing cotton 4 and an exhaust flange 9 are designed inside.

[0027] The sound-absorbing cotton 4 is closely attached to the inner surface of the assembly housing 1 and is fixed on the assembly housing 1 by screws.

[0028] The silencer tube 6 is evenly arranged inside the assembly housing 1, its lower part is connected to the air distribution plate 7, and its upper part is fixed to the assembly housing 1 through the fixing plate 5. The air distribution plate 7 is welded to the assembly housing 1 as a whole.

[0029] The exhaust flange 9 is arranged at the upper part of the assembly housing 1, and other pipelines can be externally connected according to actual needs to lead the gas to other required areas, or it can be directly emptied when there is no need to discharge it to other areas.

[0030] A drain ball valve 8 is designed at the lower part of the assembly housing 1, and small particle impurities can be discharged by reverse purging at the drain ball valve 8, which increases the convenience of sewage discharge.

[0031] Working principle: When the utility model is in use, after the gas passes through the intake pipe 3, it first enters the cavity between the assembly housing 1 and the lower part of the air distribution plate 7 for buffering, and then through the guiding action of the air distribution plate 7, the gas evenly enters the silencer tube 6, and then the silenced and noise-reduced gas is discharged through the exhaust flange 9.

[0032] The above specific implementation manners are only specific cases of the utility model. The patent protection scope of the utility model includes but is not limited to the above specific implementation manners. Any appropriate changes or modifications made by any person skilled in the art who meets the claims of the utility model shall fall within the patent protection scope of the utility model.
