Abstract

The utility model discloses an interior round square outside rectangle array silencer. Relates to an improvement of an array type silencer. The array muffler with the good muffling effect and the square inside and outside comprises a cuboid shell and muffling units which are fixed in the shell and arranged in a matrix mode, wherein a supporting unit is arranged between every two adjacent muffling units, each supporting unit comprises a first supporting plate and a second supporting plate which are fixed on two sides of each muffling unit, the supporting plates of the adjacent muffling units are mutually abutted, and a muffling material layer is fixed on the wall of each supporting plate. The auxiliary air inlet channel formed by the supporting plate prevents air flow from directly vibrating gaps between the outer frames, so that the noise elimination effect is better.

Description

Rectangular array silencer with inner circle and outer square

Technical Field

The utility model relates to a silencer especially relates to the improvement of array silencer.

Background

At present, a matrix muffler is generally a chinese patent application with application number 2018112634415 disclosed by national bureau 2018-12-28, and includes a housing in a rectangular shape and a plurality of noise elimination units, wherein the plurality of noise elimination units are distributed in the housing in a matrix shape, adjacent noise elimination units are tightly attached to each other, the noise elimination units are tightly attached to the inner wall of the housing, noise elimination holes are formed in the noise elimination units along the length direction of the noise elimination units, and the cross sections of the noise elimination holes are circular. The invention has the advantages of exquisite structure, good stability, good air flow passing effect and good noise elimination effect on air flow on the whole. However, the silencing units are connected together by bolts, and when airflow passes through the silencing units, vibration is generated among the silencing units, so that sound is generated to generate noise, and the silencing effect is influenced.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides an interior round square rectangle array silencer that noise elimination effect is good.

The utility model discloses a following technical scheme realizes: the array muffler comprises a cuboid shell and silencing units fixed in the shell in a matrix arrangement, wherein a supporting unit is arranged between every two adjacent silencing units, each supporting unit comprises a first supporting plate and a second supporting plate which are fixed on two sides of each silencing unit, the supporting plates of the adjacent silencing units are mutually abutted, and silencing material layers are fixed on the walls of the supporting plates.

The silencing unit comprises an outer frame and a silencing block filled in the outer frame, and the first supporting plate and the second supporting plate are fixed on the outer wall of the outer frame.

The silencing block is provided with a silencing hole, and the silencing hole is formed in the center of the silencing block.

The outer frame is provided with fixing holes, and adjacent silencing units penetrate through the fixing holes through bolts to be fixed with each other.

Clamping plates extending out of the center of the outer frame are arranged at the corners of the outer frame, and the silencing blocks are clamped and fixed between the clamping plates.

Compared with the prior art, the utility model discloses utilize the cooperation between the bearing plate to form supplementary inlet channel, still set up the noise elimination layer that noise elimination material made on the bearing plate, when supplementary admitting air, just can avoid the air current directly to the gap production vibration between the frame through the supplementary inlet channel that the bearing plate constitutes like this, noise cancelling effect is better like this.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural view of the present muffler unit;

in the figure: 1. a housing; 2. a sound attenuation unit; 21. an outer frame; 22. a sound-deadening aperture; 23. a noise elimination block; 24. a first support plate; 25. a second support plate; 26. an auxiliary intake passage.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-2, the array muffler with an outer and inner square shape includes a housing with a rectangular shape and noise elimination units 2 fixed in the housing and arranged in a matrix, a support unit is disposed between adjacent noise elimination units 2, the support unit includes a first support plate 24 and a second support plate 25 fixed on two sides of the noise elimination unit 2, the support plates of adjacent noise elimination units 2 are abutted against each other, and a noise elimination material layer is fixed on the wall of the support plate. The auxiliary air inlet channel 26 is formed by matching the supporting plates, and the silencing layer made of silencing material is arranged on the supporting plates, so that when auxiliary air inlet is carried out, the auxiliary air inlet channel 26 formed by the supporting plates can prevent air flow from directly vibrating gaps between the outer frames 21, and the silencing effect is better.

The sound attenuation unit 2 comprises an outer frame 21 and a sound attenuation block 23 filled in the outer frame 21, and the first support plate 24 and the second support plate 25 are fixed on the outer wall of the outer frame 21. The auxiliary air inlet channel 26 is formed by matching the supporting plates, and the silencing layer made of silencing material is arranged on the supporting plates, so that when auxiliary air inlet is carried out, the auxiliary air inlet channel 26 formed by the supporting plates can prevent air flow from directly vibrating gaps between the outer frames 21, and the silencing effect is better.

The silencing block 23 is provided with a silencing hole 22, and the silencing hole 22 is arranged in the center of the silencing block 23. The silencing holes 22 serve as the main air intake passage through which air circulates primarily, and the silencing blocks 23 eliminate noise as the air flows during the flow-through process.

The outer frame 21 is provided with fixing holes, and the adjacent silencing units 2 penetrate through the fixing holes through bolts to be fixed with each other.

Clamping plates extending towards the center of the outer frame 21 are arranged at the corners of the outer frame 21, and the silencing blocks 23 are clamped and fixed between the clamping plates. The clamping plates have certain elasticity, so when the silencing block 23 is fixed between the clamping plates, the clamping plates tightly clamp and fix the silencing block 23 in the outer frame 21 by using the elasticity, and the silencing block can be conveniently fixed by using bolts and the like.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
