Abstract
Description
Technical field
The utility model relates to a kind of air draft groove, is specifically related to a kind of air draft groove that has soundproof effect.
Background technique
The noise pollution of blower is multi-point and wide-ranging.Existing technology often only installs wind inlet silencing device additional on the blower air sucking mouth when solving this noise like, disc type is arranged, and cartridge type is also arranged, but the noise elimination effect is bad.Its reason is that the noise of blower not only is the intake grill place, derives from blower casing and motor greatly simultaneously.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 industrial pollution such as oxygen compressor, air compressor, ball mushroom machine, blower fan and noise pollution such as civilian and other association area has dropped into great amount of manpower and material resources and financial resources.But still have design and structural defective: 1. the main components and parts of noise adopt 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 influenced the proper functioning of axial-flow blower, thereby has reduced the effect of heat dissipation ventilation, and energy consumption is also bigger.First-selection adds acoustic hood in the equipment outside when solving this problem of noise, but adds the heat radiation that has influenced equipment such as blower, compressor behind the acoustic hood again, and in order to solve heat dissipation problem, we are some air intake ducts of design and air draft groove on acoustic hood usually.And the place is provided with the pressure air draft at the air draft groove, promptly generally selects axial-flow blower for use, has caused the secondary noise so again.
Summary of the invention
Goal of the invention: the purpose of the utility model is in order to overcome deficiency of the prior art, a kind of New of Air groove that reduces the ventilating fan noise to be provided.
Technological scheme: the described novel noise reduction air draft groove of the utility model; 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, on this top cover, be fixed with the air draft baffler, between this air draft baffler, be fixed with acoustic(al)absorbent.
Said acoustic(al)absorbent comprises the middle part acoustic(al)absorbent and is located at these acoustic(al)absorbent both sides, middle part and leans against the side acoustic(al)absorbent on the said air draft noise reduction wall that this side acoustic(al)absorbent and middle part acoustic(al)absorbent fixedly are located in the said ventilation channel through supporting element.
Below said acoustic(al)absorbent, be provided with ventilating fan.
Said ventilating fan is fixed on the joint of said acoustic hood and said ventilation channel through bolt arrangement.
Be provided with overhead guard on said air draft baffler top.
In actual production, equipment such as blower, air compressor can produce very big noise, so entire equipment need install acoustic hood additional; Solve the running noise problem, this acoustic hood is provided with air intake duct and air draft groove, and air draft groove place is provided with ventilating fan; Air intake duct is through natural air inlet, and the air draft groove adopts axial-flow blower to force air draft, solves the heat dissipation problem of acoustic hood; And the ventilating fan noise at air draft groove place is bigger, so in the air draft groove, silencer need be set.Novel noise reduction air draft slot device is simple in structure, has guaranteed the low noise operation of entire equipment such as blower, air compressor.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: adopt silencer, solved the secondary noise pollution that ventilating fan produces in the acoustic hood.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Of Fig. 1; The described novel noise reduction air draft groove of the utility model 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; On this top cover 3, be fixed withair draft baffler 4, between thisair draft baffler 4, be fixed with acoustic(al)absorbent 5; Said 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 leans against the side acoustic(al)absorbent 7 on saidair draft baffler 4 walls that this side acoustic(al)absorbent 7 and middle part acoustic(al)absorbent 6 fixedly are located in the said ventilation channel 2 through supporting element 8; Below said acoustic(al)absorbent 5, be provided with ventilating fan 9; Said ventilating fan 9 is fixed on the joint of said acoustic hood 1 and said ventilation channel 2 through bolt arrangement 10; Be provided with overhead guard 11 on saidair draft baffler 4 tops.The utility model 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 entire equipment such as blower, air compressor.
The utility model does not relate to all identical with the existing technology existing technology that maybe can adopt of part to be realized.
