Abstract
The utility model provides an exhaust muffler device, which comprises a case body, a conical diffuser section, a diffusion tank, a saddle-shaped sound insulation baffle, and a conical guide shell which is arranged in the diffusion tank, wherein, small holes are formed on all the case body inner part, the diffusion tank and the saddle-shaped sound insulation baffle; and the inner parts of the case body and saddle-shaped sound insulation baffle are filled with sound absorption materials. The exhaust muffler device integrates the small holes and a labyrinth anechoic structure as a whole, thereby having the advantages of small size, light weight, low cost, simple structure, obvious anechoic effect and the like, and realizing muffling and airflow diverting in a limited space simultaneously, therefore, the exhaust muffler device is particularly suitable for horizontal exhaust equipment.
Description
Technical field
The utility model relates to a kind of silencer, especially a kind of air exhaust muffler device.
Background technique
Existing exhaust silencer adopts the tubular type dissipative muffler usually, and such silencing apparatus inside is provided with a plurality of independently ducts, filling sucting sound material between each duct, and the duct inwall is provided with a large amount of apertures, and air-flow is realized eliminating the noise through the duct time.Such silencing apparatus noise elimination effect is better, the exhaust flow resistance is also less.But such silencing apparatus can only be installed in the straight length usually, and volume and weight are bigger, resembles horizontal equipment exhaust, and exhaust need change airflow direction, and needing increases extra accessory, is difficult to realize in narrow space.
Summary of the invention
The purpose of this utility model provide a kind of volume little, in light weight, simple in structure, eliminate the noise effective and can realize the air exhaust muffler device of air flow divert.Technical solution of the present utility model is, silencing apparatus comprises casing, at casing blowhole place one taper diffuser is set, be provided with diffusion barrel and streamlined saddle type sound insulation baffle in the casing, the taper diffuser is connected with diffusion barrel, 2-4 taper guide shell on average is set in the diffusion barrel, saddle type sound insulation baffle is arranged between the exhaust port of diffusion barrel and casing, diffusion barrel, cabinet wall and saddle type sound insulation baffle are provided with aperture, casing and saddle type sound insulation baffle inside all are filled with sound-absorbing material, as superfine glass silk floss.Compare with silencing apparatus in the past, the utility model integrates aperture, mazy type noise elimination structure, have that volume is little, in light weight, cost is low, simple in structure, characteristics such as the noise elimination effect is remarkable, in limited space, realized noise elimination and air flow divert simultaneously, be specially adapted to horizontal equipment exhaust.

Embodiment
As shown in the figure, device comprises casing 4, the blowhole place of described casing 4 is provided with a taper diffuser 3 and is connected with diffusion barrel 1 in the casing, 2-4 taper guide shell 2 on average is set in the diffusion barrel 1, one streamlined saddle type sound insulation baffle 5 is set between the exhaust port 6 of diffusion barrel 1 and casing 4, the inwall of described diffusion barrel 1, casing 4 and saddle type sound insulation baffle 5 are provided with aperture, and described casing 4 and saddle type sound insulation baffle 5 inside are filled with sound-absorbing material.
At first 3 expansions reduce flow velocity to the gas that equipment is discharged through diffuser, realize preliminary the noise elimination through aperture diffusion barrel 1 again, for reducing the exhaust flow resistance loss, 2-4 guide shell 2 is set in aperture diffusion barrel 1, make air-flow evenly by aperture diffusion barrel 1, air-flow enters in the sound proof box body 4 after changing direction, and sound insulation casing 4 inwalls are provided with aperture and have filled sound-absorbing material in inside, realize the secondary noise elimination.Saddle type sound insulation baffle 5 places between aperture diffusion barrel 1 and the relief opening 6, avoids noise from relief opening 6 outside direct radiations, and saddle type insulates against sound that baffle 5 surfaces also are provided with aperture and at inner filling sucting sound material, with raising noise elimination effect simultaneously.The air-flow of discharging from aperture diffusion barrel 1 flows through from saddle type sound insulation baffle 5 both sides and enter atmosphere in the lump from relief opening 6 after joining in the top.For reducing flow resistance, saddle type sound insulation baffle 5 is taked airflow design.
Embodiment
System comprises casing 4, the blowhole place of described casing 4 is provided with a taper diffuser 3 and is connected with diffusion barrel 1 in the casing, 3 taper guide shells 2 on average are set in the diffusion barrel 1, one streamlined saddle type sound insulation baffle 5 is set between the exhaust port 6 of diffusion barrel 1 and casing 4, the inwall of described diffusion barrel 1, casing 4 and saddle type sound insulation baffle 5 are provided with aperture, and described casing 4 and saddle type sound insulation baffle 5 inside are filled with superfine glass silk floss.
At first 3 expansions reduce flow velocity to the exhaust of combustion machine through diffuser, realize preliminary the noise elimination through aperture diffusion barrel 1 again, for reducing the exhaust flow resistance loss, 3 guide shells 2 are set in aperture diffusion barrel 1, make air-flow evenly by aperture diffusion barrel 1, air-flow enters in the sound proof box body 4 after changing direction, and sound insulation casing 4 inwalls are provided with aperture and have filled superfine glass silk floss in inside, realize the secondary noise elimination.Saddle type sound insulation baffle 5 places between aperture diffusion barrel 1 and the relief opening 6, avoids noise from relief opening 6 outside direct radiations, and the baffle of saddle type sound insulation simultaneously 5 surfaces also are provided with aperture and fill superfine glass silk floss in inside, to improve the noise elimination effect.The air-flow of discharging from aperture diffusion barrel 1 flows through from saddle type sound insulation baffle 5 both sides and enter atmosphere in the lump from relief opening 6 after joining in the top.For reducing flow resistance, saddle type sound insulation baffle 5 is taked airflow design.
