Abstract
The utility model relates to a resistive plate silencer which is used for silencing of ventilation and air conditioning systems as well as middle-low pressure gas conveying systems in industrial and civil buildings. The resistive plate silencer includes a shell which is a hollow structure; a plurality of silencing plates arranged up and down are embedded in the shell; in order to disperse sound waves, one end of each silencing plate is arc; and both the left end and the right end of the shell are connected with a transition body. The resistive plate silencer has the advantages of simple structure, little pressure loss and high silencing capacity.
Description
Technical field:
The utility model relates to a kind of silencing apparatus, and particularly a kind of resistive strip-type silencer is used for the noise elimination of ventilation, air-conditioning system and the mesolow gas delivery system of industry and civil building.
Background technique:
Silencing apparatus is to stop sound transmission and a kind of device of allowing air communication to cross, is the important measures of eliminating air power noise.Silencing apparatus is mounted on the air-flow path of aerodynamic force equipment (as blower, air compressor) or the device of the reduction noise in the inlet and exhaust system.Silencing apparatus can stop the propagation of sound wave, allows the air communication mistake, is the effective tool of control noise.At present, strip-type silencer complex structure, pressure fall from the sky or outer space and lose greatlyyer, and sound deadening capacity is little, and the noise elimination effect is bad, has influenced the environment of work and life.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, to provide a kind of simple in structure, pressure fall from the sky or outer space lose little, the resistive strip-type silencer that sound deadening capacity is big.
The purpose of this utility model is achieved through the following technical solutions: a kind of resistive strip-type silencer, comprise housing, housing is a hollow-core construction, be connected with a plurality of anechoic sheets of placing up and down on the inwall of housing, the rear and front end of anechoic sheet is embedded in the inwall of housing, for dispersed sound waves, an end of each anechoic sheet is circular arc, and the two ends, the left and right sides of housing all are connected with the transition body.
The utility model compared with prior art has the following advantages:
The utility model adopts a plurality of anechoic sheets of placing up and down, and is simple in structure like this, and pressure falls from the sky or outer space and loses for a short time, and sound deadening capacity is big, and it is effective to eliminate the noise.
Description of drawings:
Fig. 1 is the sectional view of structural representation of the present utility model;
Fig. 2 is the structural representation of A-A among Fig. 1;
Number in the figure: 1-housing, 2-anechoic sheet, 3-transition body.
Embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Show a kind of mode of execution of the resistive strip-type silencer of the utility model as Fig. 1 and Fig. 2, comprise housing 1, housing 1 is a sound-absorbing material, housing 1 is tetragonal body or cylindrical body, housing 1 is a hollow-core construction, be connected with a plurality of anechoic sheets of placing up and down 2 on the inwall of housing 1, the rear and front end of anechoic sheet 2 is embedded in the inwall of housing 1, the two ends, the left and right sides of housing 1 all are connected with transition body 3, one end of each anechoic sheet 2 is circular arc, and one sound wave can be divided into the above sound wave of twice when running into the circular arc end face, has reduced the frequency of original sound wave, make that sound wave energy is better absorbed, the two ends, the left and right sides of housing 1 all are connected with transition body 4.
The utility model utilizes acoustic resistance to eliminate the noise, and adopts a plurality of anechoic sheets of placing up and down 2 in housing 1, and is simple in structure like this, pressure fall from the sky or outer space lose little, pressure loss 25-55Pa, sound deadening capacity is big, sound deadening capacity Δ R 〉=20-25dB (A), it is effective to eliminate the noise, and is the dissipative muffler of using always.
