Description
Technical field
The present invention relates to a kind of only absorbing sweeper truck noise reduction box, belongs to field of environment protection cleaning outfit class.
Background technology
With the increase of highway in China mileage, the foundation of highway network, it is also proposed highway cleaning equipment higher and higher
Requirement.Found through patent retrieval, Chinese patent grant number 201310605801.6, patent application day is November 26 in 2013
Number, patent name is only absorbing sweeper truck, discloses a kind of only absorbing sweeper truck.Only absorbing sweeper truck is that one kind is inhaled using vacuum
Dirt principle carries out road surface cleaning and dust, the vehicle of granular substance recycling.Only absorbing sweeper truck in operation, transport at a high speed by wind turbine
Turn, produce noise.Using a kind of only absorbing sweeper truck noise reduction box, only absorbing sweeper truck fan noise can be reduced.
The content of the invention
The present invention is for prior art deficiency and defect, there is provided a kind of only absorbing sweeper truck noise reduction box, can reduce pure suction
Formula road sweeper fan noise.
In order to realize foregoing invention purpose, the technical solution adopted in the present invention is：A kind of only absorbing sweeper truck noise reduction box,
Including wind turbine, it is characterised in that further include：Noise reduction box air inlet, noise reduction box shell, outer sound arrester, outer sound-absorbing shell, liner are solid
Determine device, interior sound arrester, interior sound-absorbing shell, upper guiding device, lower guiding device, interior sound arrester, outer sound arrester absorb gas
The noise that body flowing produces, upper guiding device, the circulating direction of lower guiding device guiding air-flow, reduces gas circulating resistance, carries
The percent of pass of high gas flow, so as to have the function that to reduce noise, its connection mode is：Wind turbine is connected with noise reduction box air inlet, case
Air inlet is connected with noise reduction box shell, and noise reduction box shell is connected with outer sound arrester, and outer sound arrester connects with outer sound-absorbing shell phase, drop
Make an uproar case shell, interior sound-absorbing shell is connected with liner fixing device, and upper guiding device connects with interior sound-absorbing shell phase, interior sound arrester and interior suction
Sound shell phase connects, and interior sound-absorbing shell is connected with lower guiding device.
Outer sound arrester material be glass fibre, acoustical cotton, sound deadening coating, plasterboard with holes, sound-absorbing plank, foamed aluminium,
Polyester fibre acoustic panel, foam glass.Outer sound arrester has sound absorption function, reduces noise caused by air-flow.
Interior sound arrester material is glass fibre, acoustical cotton, sound deadening coating, plasterboard with holes, sound-absorbing plank, sound-absorbing painting
Material, foamed aluminium, polyester fibre acoustic panel, foam glass.Interior sound arrester has sound absorption function, reduces and makes an uproar caused by air-flow
Sound.
Upper guiding device, the sealing of lower guiding device are tapered.Upper guiding device cone angle is 45-60 degree, and diffusive gas flow, reduces
Air outlet resistance, makes outlet air unobstructed.Lower guiding device cone angle is 15-30 degree, and guiding air-flow is evenly distributed in interior sound arrester
Between outer sound arrester, 15-30 degree cone angle reduces the resistance of air-flow.
Outer sound-absorbing shell, interior sound-absorbing shell are sieve, punched-plate, cloth, strainer.Outer sound-absorbing shell, interior sound-absorbing shell are net structure,
Interior sound arrester, outer sound arrester pass through net structure and air flow contacts.
When wind turbine runs at high speed, air-flow flows through inside noise reduction box, and outer sound arrester and interior sound arrester filter out portion
Divide noise, so as to reduce only absorbing sweeper truck noise.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention：
Embodiment;
As shown in the figure, a kind of only absorbing sweeper truck noise reduction box, including：Wind turbine 1, it is characterised in that further include：Noise reduction box air inlet

Sound-absorbing shell 9, lower guiding device 10,3 peripheral seal of noise reduction box shell, lower end are connected with noise reduction box air inlet 2, and air-flow is arranged in upper end
Go out；Noise reduction box shell 3, outer sound-absorbing shell 5 are connected with outer sound arrester 4, sound-absorbing shell 9 in the fixation of liner fixing device 6, upper water conservancy diversion dress
Put 7 with interior sound-absorbing shell 9 to be connected, interior sound arrester 8 is connected with interior sound-absorbing shell 9, and interior sound-absorbing shell 9 is connected with lower guiding device 10.On
The figure direction of arrow is airflow direction.When wind turbine 1 operates, the air-flow that wind turbine 1 is discharged enters outer sound-absorbing shell 5 through noise reduction box air inlet 2
In the cavity formed with interior sound-absorbing shell 9, air-flow is broken up shunting by lower guiding device 10, and outer sound arrester 4, interior sound arrester 8 are gone
Remove the noise that part fan operating produces, upper 7 dredging flow of guiding device discharge.
