Abstract
The utility model discloses a no filler shell and tube silencer, including silencer metal casing all around, both ends are equipped with to connect and use the angle bar flange about the muffler shell, both ends are equipped with silencer seal head plate about the muffler shell, be equipped with between the silencer seal head plate of both ends and be a plurality of perforation noise elimination pipe of indulging transverse arrangement, the utility model discloses simple structure does not fill sound absorbent, makes more portably, and the product is the environmental protection more, has satisfied the have relatively high expectations demand in place of cleanliness factor, has better economic benefits and social.
Description
[technical field]
The utility model relates to a kind of sound suppressor for environmental protection noise reduction engineering, especially a kind of non-filler shell and tube sound suppressor.
[background technology]
Along with the progress of society, the fast development of modernization industry, all kinds of noise pollution has a strong impact on people's work, studying and living, especially in the environment that some are open, as industrial working noise, traffic noise, the noise sources such as noise of equipment, reduce or stress release treatment so people have invented various sound suppressor, but existing sound suppressor is adopt at metal construction inside filling acoustic absorbant to reach the form of sqouynd absorption lowering noise mostly, although the effect reducing noise source can be played, but acoustic absorbant such as the glass wool etc. of filling can produce secondary pollution to environment simultaneously, the feature of environmental protection is poor, and not easily produce, the requirement of people to environmental protection can not be met.
Therefore, for avoiding above-mentioned technical matters, the necessary one that provides has structure improved sound suppressor, to overcome described defect of the prior art.
[utility model content]
In order to overcome above shortcomings part in prior art, it is simple that the purpose of this utility model is to provide a kind of structure, and easily produce, easy accessibility is laborsaving, the non-filler shell and tube sound suppressor that installation cost is low.
In order to reach above-mentioned object, the utility model adopts following concrete technical scheme: non-filler shell and tube sound suppressor, comprise the metal shell of sound suppressor surrounding, two ends, described muffler shell left and right are provided with connection angle iron flange, two ends, described muffler shell left and right are provided with sound suppressor head plate, are provided with in vertical transversely arranged a plurality of perforation hush tubes between the sound suppressor head plate of described two ends.
Further, perforation hush tube described in the utility model is cylinder hollow structure, and its two ends are that openend forms the perforation hush tube with hush tube air vent.
The utility model advantage is compared with prior art: the utility model structure is simple, not filling sucting sound material, and manufacture easier, product is environmental protection more, meet to purity requirements high field demand, there is good economic benefit and social benefit.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
[embodiment]
In order to explain the technical solution of the utility model further, below by instantiation, the utility model is elaborated.
Refer to shown in Figure of description 1 and Fig. 2, the utility model is non-filler shell and tube sound suppressor, comprise muffler shell 4, outside described muffler shell about 4 two ends, surrounding is provided with sound suppressor angle iron flange 1, described muffler shell about 4 two ends are provided with sound suppressor head plate 2, be provided with in vertical transversely arranged a plurality of perforation hush tubes 3 between described two ends sound suppressor head plate 2, described perforation hush tube 3 is cylinder hollow structure, its two ends are that openend forms the perforation hush tube with hush tube air vent 5, the utility model structure is simple, not filling sucting sound material, manufacture easier, product is environmental protection more, meet to purity requirements high field demand, there is good economic benefit and social benefit.
But above-mentioned embodiment is exemplary, being to better enable those skilled in the art understand this patent, can not being interpreted as it is restriction this patent being comprised to scope; As long as according to this patent disclose any equivalent change done or the modification of spirit, all fall into the scope that this patent comprises.
