Abstract
The invention relates to a novel silencing exhaust groove, which comprises an exhaust channel formed on the upper part of an acoustic shield, and top covers arranged on two sides of the bottom of the exhaust channel, wherein the top covers are fixedly provided with exhaust silencers; and a sound absorption body is arranged between the exhaust silencers. A silencer device is adopted to solve the problem of secondary noise pollution generated by exhaust fans in the acoustic shield.
Description
Technical field
The present invention relates to a kind of air exhaust slot, be specifically related to a kind of air exhaust slot with soundproof effect.
Background technique
The noise pollution of blower is multi-point and wide-ranging.Prior art often only installs wind inlet silencing device additional in the blower air sucking mouth when solving this noise like, disc type is arranged, and cartridge type is also arranged, but soundproof effect is bad.Its reason is that the noise of blower not only is the intake grill place, derives from simultaneously greatly blower casing and motor.Moreover, install silencing apparatus additional at its intake grill, have because the silencing apparatus resistance is excessive, make electromotor overload and shut down.Had a strong impact on its functional reliability.At present, the protection of people's pay attention to day by day environment, the improvement for the industrial pollution such as oxygen compressor, air compressor, ball mushroom machine, blower fan and the noise pollution such as civilian and other association area has dropped into a large amount of human and material resources and financial resources.But still have design and structural defective: 1. the noise main components adopts simple insulation board, thereby defening effect is bad, can not meet customer need well and national environmental standard; 2. heat dissipation ventilation places in the cover with axial-flow blower, because case temperature is too high, has affected the normal operation of axial-flow blower, thereby has reduced the effect of heat dissipation ventilation, and energy consumption is also larger.First-selection adds acoustic hood in the equipment outside when solving this problem of noise, but adds the heat radiation that has affected again the equipment such as blower, compressor behind the acoustic hood, and in order to solve heat dissipation problem, we are usually at acoustic hood some air intake ducts of design and air exhaust slot.And at the air exhaust slot place pressure air draft is set, namely generally selects axial-flow blower, caused so again quadratic noise.
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome deficiency of the prior art, a kind of New of Air groove that reduces the ventilating fan noise is provided.
Technological scheme: Novel noise-reduction air exhaust slot of the present invention, comprise the ventilation channel that is located at acoustic hood top, and the top cover that is located at these both sides, ventilation channel bottom, be fixed with the air draft baffler at this top cover, between this air draft baffler, be fixed with acoustic(al)absorbent.
Described acoustic(al)absorbent comprises the middle part acoustic(al)absorbent and is located at these acoustic(al)absorbent both sides, middle part and lean against side acoustic(al)absorbent on the described air draft noise reduction wall, and this side acoustic(al)absorbent and middle part acoustic(al)absorbent fixedly are located in the described ventilation channel by supporting element.
Below described acoustic(al)absorbent, be provided with ventilating fan.
Described ventilating fan is fixed on the joint of described acoustic hood and described ventilation channel by bolt arrangement.
Be provided with overhead guard on described air draft baffler top.
In actual production, the equipment such as blower, air compressor can produce very large noise, so whole equipment need to install acoustic hood additional, solve the running noise problem, this acoustic hood is provided with air intake duct and air exhaust slot, the air exhaust slot place is provided with ventilating fan, air intake duct is by natural air inlet, and air exhaust slot adopts axial-flow blower to force air draft, solves the heat dissipation problem of acoustic hood, and the ventilating fan noise at air exhaust slot place is larger, so need to arrange silencer in air exhaust slot.The Novel noise-reduction air exhaust slot apparatus structure is simple, has guaranteed the low noise operation of the whole equipment such as blower, air compressor.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: adopt silencer, solved the secondary noise pollution that ventilating fan produces in the acoustic hood.
Description of drawings
Fig. 1 is structural representation of the present invention.
Wherein:
1, acoustic hood; 2, ventilation channel; 3, top cover; 4, air draft baffler; 5, acoustic(al)absorbent; 6, middle part acoustic(al)absorbent; 7 side acoustic(al)absorbents; 8, supporting element; 9, ventilating fan; 10, bolt arrangement; 11, overhead guard
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As described in Figure 1, Novel noise-reduction air exhaust slot of the present invention comprises the ventilation channel 2 that is located at acoustic hood 1 top, and the top cover 3 that is located at these both sides, ventilation channel 2 bottom, be fixed with air draft baffler 4 at this top cover 3, between this air draft baffler 4, be fixed with acoustic(al)absorbent 5; Described acoustic(al)absorbent 5 comprises middle part acoustic(al)absorbent 6 and is located at these middle part acoustic(al)absorbent 6 both sides and lean against side acoustic(al)absorbent 7 on described air draft baffler 4 walls, and this side acoustic(al)absorbent 7 and middle part acoustic(al)absorbent 6 fixedly are located in the described ventilation channel 2 by supporting element 8; Below described acoustic(al)absorbent 5, be provided with ventilating fan 9; Described ventilating fan 9 is fixed on the joint of described acoustic hood 1 and described ventilation channel 2 by bolt arrangement 10; Be provided with overhead guard 11 on described air draft baffler 4 tops.The present invention is simple in structure, adopts silencer, has solved the secondary noise pollution that ventilating fan 9 produces in the acoustic hood, has also guaranteed the low noise operation of the whole equipment such as blower, air compressor.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
