Technical Field

The invention relates to a novel silencing pipeline.

Background

In industrial and mining enterprises or large-scale machine processing workshops, large-scale fans or engines of large-scale equipment inside the large-scale fans are often both medium and low frequency noise sources, and the large-scale fans or engines have strong scattering capacity and have large hearing damage to field workers.

In a workshop design process, a single room is adopted to reduce noise of a fan, and the influence of the fan on the workshop is reduced by adopting a sound insulation and noise reduction mode. The noise elimination pipeline is used as an effective sound insulation and noise reduction structure thereof, and is widely applied to noise reduction treatment of the fan.

However, the existing muffling pipelines have limited noise reduction capability, and are often more prone to exhaust air and ventilate or discharge noise outdoors, so that although indoor noise pollution can be effectively reduced, the quality of life of the whole industrial park is seriously affected, and unnecessary complaints are often incurred.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a novel silencing pipeline.

A novel silencing pipeline comprises a main frame; the main frame is formed by splicing a bent pipe part and a plurality of straight pipe parts, an air inlet and an air outlet are respectively arranged at two ends of the main frame, a plurality of silencing pieces distributed at equal intervals are arranged in the main frame, the silencing pieces are in a wedge shape at the air inlet, and the tip parts of the wedge shape are flush with the end parts of the air inlet.

Preferably, the outer walls of the straight pipe part and the bent pipe part are sequentially provided with a galvanized steel plate, environment-friendly glass wool, a damping pad, a galvanized steel plate, environment-friendly glass wool, black glass fiber wool and a galvanized hole plate from outside to inside.

Preferably, the silencing sheet is respectively made of environment-friendly glass wool, black glass fiber felt and a galvanized hole plate from inside to outside.

Preferably, the elbow part and the straight pipe part are connected through a buckle, and the straight pipe part is connected through a buckle.

Preferably, the bent pipe portion has a bending angle of 90 degrees.

Preferably, adjacent straight tube portions are connected by a socket, the socket having an elastic gasket disposed therein.

Preferably, the thickness of the elastic sealing gasket is 3 mm.

Preferably, the bottom of body frame is equipped with the T shape lead screw that a plurality of equidistance distributes, T shape lead screw on the cover be equipped with the nut, the nut link to each other with the body frame. The height of the silencing pipeline can be finely adjusted through the T-shaped screw rod, so that the requirement of noise reduction of equipment is better met.

Preferably, the number of the noise-reduction sheets is four.

Has the advantages that:

this device can be better introduces the noise from the air inlet through the design of wedge formula to creatively install the noise reduction piece in the inside of body frame, through the combination between a plurality of noise reduction piece with the further absorption of noise, and through the design of return bend, when the noise is about to discharge, the design through the return bend reduces the further weakening of the energy of noise, prevents the emergence of noise disturbing citizen's phenomenon.

Compared with the existing silencing pipeline, the noise reduction capacity of the product can be effectively improved by at least 60%.
