Preferably, the knob that presses is clamped with air-flow nozzle, and nose end presses first flange on the right side of the air-flow nozzle.
Preferably, the opening on the hollow shelf is not arranged on the same straight line, and filled with sound absorption cotton in hollow shelf.
Preferably, it is connected through a screw thread between the first flange, second flange and housing.
Preferably, the housing includes outer housing layer, noise reduction layer, inner housing layer.
Compared with prior art, the beneficial effects of the utility model are：The utility model is to be applicable in subtract with industry nozzle
It makes an uproar device, including housing, is provided on the left of housing and presses knob, pressed knob and the silencing apparatus and noise nozzle are consolidated
It is fixed so that the air-flow in nozzle enters silencing apparatus, the hollow shelf being open in housing equipped with several bands, the opening of hollow shelf
It is not arranged on the same straight line so that air-flow increases by the distance of silencing apparatus, and sound absorption cotton is filled in hollow shelf, reduces
The noise that air-flow vibrations are brought, air-flow enter right side after being come out from hollow shelf and cover, be provided with many through-holes in capping, reduce
The noise that air-flow generates, it is therefore seen that the utility model has the advantages of simple structure, noise reduction effect is notable, and convenient disassembly, is produced into
This is low, is the high performance-price ratio denoising device of industrial nozzle noise abatement.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
~2 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of simple silencing apparatus of industry nozzle, including
Housing 1 is equipped with first flange 2 in the housing 1 at the air flow inlet 15 of left side, 1 left side of housing, which is provided with, presses knob 4,
The periphery of knob 4 of pressing is equipped with external screw thread 6, and the housing 1 is provided with internal thread 3 pressing at knob 4, described to press knob
Gasket 5, the hollow shelf 8 being open in the housing 1 equipped with several bands are arranged on 4,1 right side of housing is equipped with second flange
