Description
Technical field
The present invention relates to a kind of only absorbing sweeper truck noise reduction box, belong 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 more and more higher to highway cleaning equipment
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 a kind of using vacuum suction
Dirt principle carries out the vehicle that road surface cleaning and dust, granular substance are reclaimed.Only absorbing sweeper truck in operation, transport at a high speed by blower fan
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 blower fan, it is characterised in that also include：Noise reduction box air inlet, noise reduction box shell, outer sound arrester, outer sound-absorbing shell, inner bag 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 is produced, upper guiding device, lower guiding device guide the circulating direction of air-flow, reduce gas circulating resistance, carry
The percent of pass of high gas flow, the effect of noise is reduced so as to reach, and its connected mode is：Blower fan 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 inner bag 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 the noise produced 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 making an uproar produced by air-flow
Sound.
Upper guiding device, the sealing of lower guiding device are tapered, and upper guiding device cone angle is 45-60 degree, and diffusive gas flow is reduced
Air outlet resistance, makes air-out 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 screen cloth, punched-plate, cloth, filter screen.Outer sound-absorbing shell, interior sound-absorbing shell are network structure,
Interior sound arrester, outer sound arrester pass through network structure and air flow contacts.
When blower fan runs at high speed, air-flow flows through from 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
Accompanying drawing is structural representation of the invention：
Specific embodiment;
As illustrated, a kind of only absorbing sweeper truck noise reduction box, including：Blower fan 1, it is characterised in that also include：Noise reduction box enters
Air port 2, noise reduction box shell 3, outer sound arrester 4, outer sound-absorbing shell 5, inner bag fixing device 6, upper guiding device 7, interior sound arrester
8th, interior sound-absorbing shell 9, lower guiding device 10, the peripheral seal of noise reduction box shell 3, lower end are connected with noise reduction box air inlet 2, and upper end is by gas
Stream discharge；Noise reduction box shell 3, outer sound-absorbing shell 5 are connected with outer sound arrester 4, and inner bag fixing device 6 fixes interior sound-absorbing shell 9, above leads
Stream device 7 is connected with interior sound-absorbing shell 9, and interior sound arrester 8 is connected with interior sound-absorbing shell 9, interior sound-absorbing shell 9 and the lower phase of guiding device 10
Even.The upper figure direction of arrow is airflow direction.When blower fan 1 is operated, the air-flow of the discharge of blower fan 1 enters outer suction through noise reduction box air inlet 2
In the cavity that sound shell 5 is formed with interior sound-absorbing shell 9, air-flow is broken up shunting, outer sound arrester 4, interior sound-absorbing dress by lower guiding device 10
Put 8 and get rid of the noise that part fan operating is produced, the discharge of the dredging flow of upper guiding device 7.
