To close to panel 14.Structure as wind deflector 6 as a result, forms smoke chamber, can will enter in shell 1 from panel 14 and spread
Oil smoke guide to ternary blower 4, improve smoking efficiency.Wind deflector 6 increases the centrifugation supercharging effect of 4 front side of ternary blower,
Reduce the pressure loss.
Since the noise of ternary blower 4 is larger, and noise frequency range is wide, in the cavity of shell 1, is preferably located at ternary blower
4 lower section, shell 1 the bottom of cavity be provided with noise reduction module 7, referring to fig. 4~8, noise reduction module 7 includes right baffle-plate 711, right
Baffle 712, front apron 713, rear baffle 714, bottom baffle 715 and top baffle 716, width of the top baffle 716 in front and rear direction
Greater than bottom baffle 715, front apron 713 is from top to bottom gradually tilted backwards, and right baffle-plate 711 and right shell body 712 are in rough triangle
Shape, the sound absorption back chamber that thus above-mentioned each plate collectively forms is in rough triangulo column (up big and down small).Top baffle 716 is from front to back
Gradually inclination upwards, it is consistent with 4 bottom of ternary blower, the inclined direction of cover board 64 and preferred, top baffle 716 it is close or
It is close to the cover board 64 of wind deflector 6, thus increases the effect of water conservancy diversion noise reduction.
Noise reduction module 7 further includes intermediate bulkhead 72, first chamber partition 73 and second chamber partition 74.Intermediate bulkhead 72 is set
Set sound absorption back it is intracavitary, and will sound absorption back chamber be divided into positioned at the first chamber 751 in left side and positioned at the second chamber on right side
752.Preferably, intermediate bulkhead 72 can be parallel with right baffle-plate 711 or right shell body 712, the first chamber that intermediate bulkhead 72 is separated into
Room 751 and second chamber 752 are equal.
First chamber partition 73 is arranged in first chamber 751, including at least two, each first chamber partition 73 is on a left side
Extend between baffle 711 and intermediate bulkhead 72, and each first chamber partition 73 from top baffle 716 from front to back diagonally downward
It bends after extending certain distance towards rear baffle 714.One of first chamber partition 73 is located at another first chamber partition
73 lower section, each baffle and first chamber partition 73 will from top to bottom be separated at least three first in first chamber 751 as a result,
Resonant cavity 761.
Second chamber partition 74 is arranged in second chamber 752, including at least one, second chamber partition 74 is at middle interval
Extend between plate 72 and right shell body 712.One of second chamber partition 74 can be bent downward from top baffle 716 extend into it is several
Section is parallel with front apron 713, rear baffle 714 and bottom baffle 715 respectively, and second chamber 752 is thus separated into two second and is total to
Shake chamber 762, i.e. the second chamber partition 74, top baffle 716, intermediate bulkhead 72, second resonant cavity between right shell body 712
762, rest part then constitutes another the second resonant cavity 762.Can also be arranged in another resonant cavity 762 another
Two compartment spacers 74 are in tabular, extend between intermediate bulkhead 72 and right shell body 712, thus by another second resonance
Chamber 762 is divided into two.
At least two first sound-absorbing hole 771 and at least two second sound-absorbing hole 772 are offered on top baffle 716, first inhales
Acoustic aperture 771 and the second sound-absorbing hole 772 are distributed in the top of first chamber 751 and second chamber 752, it is preferred that the first sound absorption
Hole 771 can be in array-like, be covered with the surface of top baffle 716, and the surface straggly for being arranged in top baffle 716 of the second sound-absorbing hole 772.
First sound-absorbing hole 771 can be round hole, square hole, hex hole etc., a diameter of 0.8mm~3mm, this is because noise reduction mould
Block 7 is close or is close to have certain spacing between cover board 64, with ternary blower 4, and noise frequency range is wider, only by the first sound absorption
The diameter in hole 771 reduces within the above range, and noise reduction module 7 could be made to reach band limit.The diameter of second sound-absorbing hole 772
Greater than the first sound-absorbing hole 771.
Top baffle 716 has attached the first acoustical cotton 781 above, offers on the first acoustical cotton 781 and the second sound-absorbing hole 772
Matched third sound-absorbing hole 773, to increase the acoustic absorptivity of low-frequency noise.Top baffle 716, the first acoustical cotton 781 and cover board
64 can be close to mutually.The outside (arranged on left and right sides of wind deflector 6) of the side wind deflector 62 of wind deflector 6, the main body 61 of wind deflector 6
The position that rear side is located at 4 lower section of ternary blower can attach the second acoustical cotton 782, further in the noise transmission of ternary blower 4
Noise is reduced on path.
Due on 4 lower section noise transmission path of ternary blower, leftward position is mainly high-frequency noise, therefore above-mentioned first
The cavity volume of resonant cavity 761 can increase the sound absorption system to high-frequency noise less than the second resonant cavity 762, i.e. the first resonant cavity 761
Number, the second resonant cavity 762 are then semi-open space, increase the acoustic absorptivity to mid-frequency noise.This mazy resonant cavity
Increase the wide band sound absorption of the first acoustical cotton 781.
In order to reduce absorbed noise frequency, micro-pore diameter is reduced, the spacing between adjacent cells is increased, increases resonance
The height of chamber, the largest interval between each sound-absorbing hole preferably should be 1/5th of corresponding wave length of sound, preferably 8~
50mm, largest interval 70mm, the highly preferred one third that should be corresponding wave length of sound of each resonant cavity.
In order to reduce absorbed noise frequency, micro-pore diameter is reduced, the spacing between adjacent cells is increased, increases resonance
The thickness of chamber, the largest interval between each sound-absorbing hole preferably should be 1/5th of corresponding wave length of sound, the thickness of each resonant cavity
Degree preferably should be the one third of corresponding wave length of sound.
By above-mentioned arrangement, ternary blower 4 has very well 4 radiated noise of ternary blower close to noise reduction module 7
Inhibiting effect, and it is compact-sized.And the structure of noise reduction module 7, sound absorption frequency range greatly improved, can effectively absorb each frequency range
Noise.
At least one first oil dripping hole 7151 is offered on bottom baffle 715, offers the second oil dripping on the bottom plate 17 of shell 1
Hole 171 (can be corresponding with the first oil dripping hole 7151, can not also correspond to), and the position of the position of above-mentioned oil dripping hole and lubricating cup 3
Set correspondence.Even if thus there is the grease after separation to enter noise reduction module 7, the first oil dripping hole 7151 and the second oil dripping hole can also be passed through
171 are discharged to lubricating cup 3, in order to avoid influence the noise reduction effect of noise reduction module 7.
