Abstract
The invention relates to the technical field of silencing equipment, in particular to a high-efficiency silencer. The high-efficiency silencer comprises a silencer body, an air inlet, an air outlet, a first silencing chamber, a second silencing chamber, a third silencing chamber, silencing boards, a sound absorption box, sound absorption cotton and an air outlet channel, wherein the air inlet is formed at one end of the silencer body; the air outlet is formed at the other end of the silencer body; the first silencing chamber, the second silencing chamber and the third silencing chamber are arranged in the silencer body; the silencing boards are arranged among the first silencing chamber, the second silencing chamber and the third silencing chamber; the sound absorption box is arranged in the first silencing chamber; the sound absorption cotton is arranged in the second silencing chamber; the air outlet channel is arranged in the third silencing chamber; and an air bell is arranged outside the air outlet channel. The high-efficiency silencer is simple, compact and reasonable in structure, convenient and quick to assemble, reliable in connection, low in power loss, good in silencing effect, and easy to use and popularize; a purpose of silencing is achieved by disturbing an air flow and a sound wave of the silencer; the noise is reduced; air inlet and exhaust in the silencer are smooth; and the working reliability of the silencer is greatly improved.
Description
Technical field
The present invention relates to a kind of technical field of silencing equipment, especially a kind of high efficiency silencer.
Background technique
Silencing apparatus is the device of abatement pneumatic noise, is installed in the duct or on inlet and outlet mouth, while air-flow passes through, has certain consumption to noise.Existing silencing apparatus soundproof effect is poor, and intake and exhaust resistance is larger, and air flow property is poor, greatly reduces the reliability of silencing apparatus work.
Summary of the invention
In order to overcome the deficiency that existing silencing apparatus soundproof effect is poor, air flow property is poor and functional reliability is low, the invention provides a kind of high efficiency silencer.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high efficiency silencer, comprise body, suction port, air outlet, anechoic chamber one, anechoic chamber two, anechoic chamber three, acoustical panel, sound-absorbing box, acoustical cotton and outlet passageway, body one end is provided with suction port, the other end is provided with air outlet, anechoic chamber one, anechoic chamber two and anechoic chamber three is provided with in body, anechoic chamber one, between anechoic chamber two and anechoic chamber three, be equipped with acoustical panel, sound-absorbing box is provided with in anechoic chamber one, be provided with acoustical cotton in anechoic chamber two, in anechoic chamber three, be provided with outlet passageway.
According to another embodiment of the invention, comprise outlet passageway outside further and be provided with air bell.
The invention has the beneficial effects as follows, this high efficiency silencer structure is simple, compact and reasonable, fast easy to assembly, connect reliable, by upsetting the air-flow of silencing apparatus and sound wave thus reaching the object of noise elimination, reduce noise, inner intake and exhaust are smooth and easy, and power loss is little, and soundproof effect is good, substantially increase the reliability of silencing apparatus work, be easy to use and promote.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. bodies, 2. suction port, 3. air outlet in figure, 4. anechoic chamber one, 5. anechoic chamber two, 6. anechoic chamber three, 7. acoustical panel, 8. sound-absorbing box, 9. acoustical cotton, 10. outlet passageway, 11. air bells.
Embodiment
If Fig. 1 is structural representation of the present invention, a kind of high efficiency silencer, comprise body 1, suction port 2, air outlet 3, anechoic chamber 1, anechoic chamber 25, anechoic chamber 36, acoustical panel 7, sound-absorbing box 8, acoustical cotton 9, outlet passageway 10, with air bell 11, body 1 one end is provided with suction port 2, the other end is provided with air outlet 3, anechoic chamber 1 is provided with in body, anechoic chamber 25 and anechoic chamber 36, anechoic chamber 1, acoustical panel 7 is equipped with between anechoic chamber 25 and anechoic chamber 36, sound-absorbing box 8 is provided with in anechoic chamber 1, acoustical cotton 9 is provided with in anechoic chamber 25, outlet passageway 10 is provided with in anechoic chamber 36, outlet passageway 10 outside is provided with air bell 11.
During use, gas enters from suction port 2, through the noise reduction of anechoic room 1, anechoic room 25 and anechoic room 36, finally discharges from air outlet 3.This high efficiency silencer structure is simple, compact and reasonable, fast easy to assembly, connect reliable, by upsetting the air-flow of silencing apparatus and sound wave thus reaching the object of noise elimination, reduce noise, inner intake and exhaust are smooth and easy, power loss is little, soundproof effect is good, substantially increases the reliability of silencing apparatus work, is easy to use promote.
