Abstract
The utility model discloses a safe discharging silencer, comprising a silencing drum (1), silencing pieces (2), an inlet pipe (3), a rain preventing cap (4) and a discharging port (5); the silencing pieces (2) are arranged in the silencing drum (1), the inlet pipe (3) and the discharging port (5) are respectively arranged at two ends of the silencing drum (1), the rain preventing cap (4) is arranged above the inlet pipe (3), the silencing pieces (2) and the silencing drum (1) are compressed by a compressing ring (6) and a sealing packing (7) is filled between the two layers of silencing pieces (2). The safe discharging silencer has the advantages of simple structure, small size, easiness in manufacturing, low cost, good silencing property and the like.
Description
Technical field
The utility model belongs to the noise controller field, is specifically related to a kind of safety dumping silencing apparatus.
Background technique
In the prior art, the silencing apparatus of vent systems is made up of the device of acoustics filtering or sound energy consumption.The expanssion type exhaust silencer that adopts on the present internal-combustion engine, sound deadening capacity is little, and its exhaust sound is higher than the noise of other parts, becomes the main noise source of internal-combustion engine, and air-flow is big by resistance, and power loss is big, and exhaust stroke is long.And the vortex type exhaust silencer that occurs recently although it is differential to reduce exhaust noise preferably, reaches the purpose of eliminating noise, but its complex structure, manufacturing be difficulty comparatively, the cost height, air-flow is big by resistance, and power loss is more, therefore also is difficult to promote the use of.
Summary of the invention
The purpose of this utility model will overcome problems of the prior art exactly, and a kind of simple and reasonable, volume is little, sound deadening capacity is big, power loss is few safety dumping silencing apparatus is provided.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of safety dumping silencing apparatus, comprise silencing pot (1), anechoic sheet (2), inlet duct (3), rainhat (4), efflux mouthful (5), described anechoic sheet (2) is arranged on the inside of silencing pot (1), inlet duct (3) and efflux the two ends that mouthful (5) are separately positioned on silencing pot (1), rainhat (4) is installed in the top of inlet duct (3).
Described anechoic sheet (2) has two-layer, and silencing pot (1) is divided into three sections.
Compress by retainer ring (6) between described anechoic sheet (2) and the silencing pot (1).
Stuffing box packing (7) is housed between the described two-layer anechoic sheet (2).
The beneficial effects of the utility model are: safety dumping silencing apparatus of the present utility model utilizes anechoic sheet (2) and stuffing box packing (7) to absorb acoustic energy, and is simple in structure, volume is little, be easy to make, cost is low, acoustic attenuation performance good.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, silencing pot; 2, anechoic sheet; 3, inlet duct; 4, rainhat; 5, efflux mouth; 6, retainer ring; 7, stuffing box packing.
Embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified.
As shown in the figure, a kind of safety dumping silencing apparatus that the utility model provides, comprise silencing pot (1), anechoic sheet (2), inlet duct (3), rainhat (4), efflux mouthful (5), anechoic sheet (2) is arranged on the inside of silencing pot (1), inlet duct (3) and efflux the two ends that mouthful (5) are separately positioned on silencing pot (1), rainhat (4) is installed in the top of inlet duct (3); Anechoic sheet (2) has two-layer, and silencing pot (1) is divided into three sections; Compress by retainer ring (6) between anechoic sheet (2) and the silencing pot (1); Stuffing box packing (7) is housed between the two-layer anechoic sheet (2).
When a kind of safety dumping silencing apparatus of the present utility model uses, anechoic sheet (2) and stuffing box packing (7) be the noise of absorbing high-frequency or low frequency well, detects through experiment, and the maximum sound-damping qualities of silencing apparatus of the present utility model reaches 48dB, minimum sound-damping qualities reaches 35dB, has good erasure effect.
Claims (4)
1. safety dumping silencing apparatus, comprise silencing pot (1), anechoic sheet (2), inlet duct (3), rainhat (4), efflux mouthful (5), it is characterized in that: described anechoic sheet (2) is arranged on the inside of silencing pot (1), inlet duct (3) and efflux the two ends that mouthful (5) are separately positioned on silencing pot (1), rainhat (4) is installed in the top of inlet duct (3).
