Abstract

The invention relates to the field of sound insulation equipment, and discloses sound insulation equipment. The sound insulation equipment is applicable to a fan and a turbine. An outer partition board coated with a damping layer at the bottom is embedded inside an internal partition board paved with an anti-flaming layer at the bottom, so that a standard shell is formed; the standard shell and a standard inner cavity filled with a sound absorption material together form a standard board; another standard shell 1 is embedded between a partition board pressing edge and another outer partition board coated with a damping layer at the bottom and is in another inner partition board paved with a anti-flaming layer at the bottom, and the standard shell 1 and another standard inner cavity filled with a sound absorption material together form another standard board 1; a rubber shock insulation cushion is arranged between the two standard boards, and is located inside the standard board 1 through bolts and gaskets; the rubber shock insulation cushion and the standard board 1 are integrally welded through another gaskets and another nuts; and an access door and a lighting window are designed on each standard board. With the adoption of the technical scheme, the standard boards have no need of being fixed through a framework. The sound insulation equipment directly uses a hook-up bending design and a nut fitting embedding design, so that the sound insulation equipment has the advantages of simple structure, elegant appearance, and low cost.

Description

A kind of sound insulation device

Technical field

The present invention relates to the sound insulation device field, is a kind of sound insulation device.Be applicable to blower fan, steam turbine.

Background technology

The environmental requirement gap of the huge noise source of the generations such as blower fan, steam turbine, high velocity ram machine and national regulation is very far away at present.And the most project organization of noise control device is numerous and diverse, parts redundant, waste material, the inconvenient detachable maintaining of each parts, mostly be the rigidity contact easily vibrations produce noise, and serviceable life is low, outward appearance is ugly, inflammable, more be difficult to the noise reduction that reaches desirable.

Summary of the invention

The objective of the invention is to provide a kind of simple in structure, reduction cost, for convenience detach, each parts is that flexible contact is difficult for producing vibration, high life, and appearance looks elegant, fire-retardant, and the very little a kind of novel sound equipment of noise.

Technical scheme of the present invention is: in the bottom is covered with the internal partition 5 of flame-retardant layer 6, be embedded in the external partition 8 that the bottom scribbles damping layer 20, consist of the cosmetic shell, the cosmetic shell consists of style strip 1 jointly with the cosmetic inner chamber 7 that is filled with the sound absorption material; The bottom is covered with in the internal partition 11 of flame-retardant layer 12, is embedded in dividing plate flanging 10 and bottom and scribbles formation cosmetic shell between damping layer 14 external partitions 9, and the cosmetic shell consists of style strip 2 jointly with the cosmetic inner chamber 13 that is filled with the sound absorption material; Be lined with rubber vibration isolation cushion 17 between style strip 1 and the style strip 2, be locked in the style strip 2 by coupling bolt 19, pad 18, be integral by pad 16 and nut 15 assembly weldings, be designed with access door 3 and light inlet window 4 at style strip.

Owing to having adopted technique scheme, need not skeleton between style strip and the style strip and fix, directly adopt bending design all linked with one another and the pre-buried design of nut fittings, make sound insulation device simple in structure, outward appearance is generous, cost.Each style strip is designed with flame-retardant layer and realizes flame retardant effect when running into naked light, and posts Rubber shock-absorbing pad between each style strip, and inside scribbles damping layer and makes each parts become flexible contact by rigidity contact can not produce resonance noise.The style strip inner chamber is filled with the cotton acoustic absorbant that waits of sound absorption, can realize sound absorption 20～40dB (A).

In the drawings: 1, style strip; 2, style strip; 3, access door; 4, light inlet window; 5, internal partition; 6, flame-retardant layer; 7, cosmetic inner chamber; 8, external partition; 9, external partition; 10, dividing plate flanging; 11, internal partition; 12, flame-retardant layer; 13, cosmetic inner chamber; 14, damping layer; 15, nut; 16, pad; 17, rubber vibration isolation cushion; 18, pad; 19, coupling bolt; 20, damping layer.

Embodiment

The present invention is further illustrated below in conjunction with drawings and Examples.

In Fig. 1 and Fig. 2, whole sound insulation device is assembled by style strip 1 and style strip 2 modules, the external partition 8 of style strip 1 and style strip 2 and external partition 9, internal partition 5 and internal partition 11 all adopt galvanized sheet or cold-reduced sheet material, the thickness of external partition 8 and external partition 9 is 2～3mm bending and molding, internal partition 5 and internal partition 11 are that the thick zinc-plated orifice plate of 0.5～1mm is made, and the punching rate is 24%～34%.The connecting portion nut fittings of style strip 2 is formed by pad 16 and nut assembly welding, is embedded in advance in the style strip 2, only needs to get final product with coupling bolt 19 and pad 18 lockings at style strip 1 place when the assembling sound insulation device, and bolt head does not leak outside.Need the thick rubber vibration isolation cushion 17 of note 2～10mm between style strip 1 and the style strip 2.Damping layer 14 and damping layer 20 materials are pitch, and damping layer thickness is 3 times of external partition thickness, and flame-retardant layer 6 and flame-retardant layer 12 materials are nonwoven fabrics, and inner chamber 7 and inner chamber 13 filling materials are the materials such as sound absorption cotton.Style strip 1 and style strip 2, access door 3, light inlet window 4 all metalworks need to do the electrostatic dusting PROCESS FOR TREATMENT after the pickling.
