Abstract
The invention relates to the technical field of a silencer, in particular to a silencer, and the silencer comprises a primary silencer, a secondary silencer and a silencing pipe for joining the primary silencer with the secondary silencer, wherein the primary silencer is connected with a flange, both the primary silencer and the secondary silencer are in cylindrical shapes, and the cylindrical walls of the primary silencer and the secondary silencer are respectively provided with a sound absorption material. Two silencers are in cascade connection with each other, so that the silencing effect is improved; the cylindrical walls of the primary silencer and the secondary silencer are respectively provided with the sound absorption material, so that the noise is further reduced; and in addition, the silencer has the characteristics of simplicity in structure, good silencing effect, convenience in installation and long service life and is widely applicable to an airflow passage of a pneumatic device.
Description
Technical field
The present invention relates to the silencing apparatus technical field, be specifically related to silencing apparatus.
Background technique
Silencing apparatus is mounted in the low noise device that falls on the air-flow path of aerodynamic force equipment (as blower, air compressor) or in inlet and exhaust system.Silencing apparatus can stop the propagation of sound wave, allows air-flow to pass through, and is the effective tool of controlling noise.Although many similar silencing apparatuss institutes that behaves is arranged at present to be known, but in the slight change of apparatus structure form, will make soundproof effect be improved, therefore how its structure be improved, to improve soundproof effect, remain the technical problem that is worth solution in prior art.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, soundproof effect good, silencing apparatus easy for installation.
In order to solve the existing problem of background technique, the present invention is by the following technical solutions: silencing apparatus, comprise first order silencing apparatus, second level silencing apparatus and the hush tube that connects described first order silencing apparatus and second level silencing apparatus, described first order silencing apparatus is connected with flange, described first order silencing apparatus and second level silencing apparatus are tubular, and the barrel of described first order silencing apparatus and second level silencing apparatus is provided with sound-absorbing material.
Further, described sound-absorbing material is foamed plastics, plastic film or canvas.
Further, the outside of described first order silencing apparatus and second level silencing apparatus is provided with rain cover.
The present invention has following beneficial effect: silencing apparatus of the present invention, comprise first order silencing apparatus, second level silencing apparatus and the hush tube that connects first order silencing apparatus and second level silencing apparatus, and adopt the two-stage silencing apparatus to be connected in series, to improve soundproof effect; And be provided with sound-absorbing material on the barrel of first order silencing apparatus and second level silencing apparatus, further reduce noise; In addition, the characteristics such as that the present invention has is simple in structure, soundproof effect good, easy for installation, long service life are widely used on the air-flow path of aerodynamic force equipment.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing.
as shown in Figure 1, silencing apparatus, comprise first order silencing apparatus 1, second level silencing apparatus 2 and the hush tube 3 that connects described first order silencing apparatus 1 and second level silencing apparatus 2, wherein, hush tube can be connected with second level silencing apparatus with first order silencing apparatus respectively by welding procedure, and first order silencing apparatus communicates with second level silencing apparatus by hush tube, described first order silencing apparatus 1 is connected with flange 4, the effect of its flange is and silencing apparatus can be installed on the air-flow path of aerodynamic force equipment, be convenient to install, described first order silencing apparatus 1 and second level silencing apparatus 2 are tubular, the barrel of described first order silencing apparatus 1 and second level silencing apparatus 2 is provided with sound-absorbing material 5, adopt sound-absorbing material can further reach noise reduction, to improve the functional reliability of silencing apparatus.
Described sound-absorbing material 5 is foamed plastics, plastic film or canvas, and design, can not only reach good soundproof effect like this, reduces simultaneously manufacture cost.
The outside of described first order silencing apparatus 1 and second level silencing apparatus 2 is provided with rain cover 6, and the effect of its rain cover is can be rainproof, moistureproof, can work to guarantee silencing apparatus, improves silencing apparatus working life.
Explanation is at last, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, other modifications that those of ordinary skills make technological scheme of the present invention or be equal to replacement, only otherwise break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
