Embodiment
Embodiment 1
As shown in figure 1, a kind of silene system for mechanical-draft cooling tower, including disappear for the vibration damping of motor 1 and gearbox 2
Sound mechanism 3, for fan outlet air draft silencer mechanism 4, for the water drenching silencer mechanism 5 at air intake；It is described to be used for motor and change
The vibration damping silencer mechanism 3 of fast case includes some vibration-damped components 31, the one end of vibration-damped component 31 connection cooling pylon or capital construction face, and the other end connects
Loading plate 32 is connect, motor 1 and gearbox 2 are arranged on loading plate 32, the connection fan 6 of gearbox 2；The air draft silencer mechanism 4
Including at least one circle air duct 41, air duct 41 is using suction sound-insulating structure；The water drenching silencer mechanism 5 includes housing and installed in housing
The noise reduction grid 51 of interior some bloops composition.
The vibration-damped component 31 is elastic damping part or inflating vibration damping part.
Embodiment 2
It is used as the decision design of embodiment 1, in actual use, elastic damping part, such as spring, rubber, although can eliminate and shake
It is dynamic, but still there is certain solid-borne sound transmission, therefore, the present invention preferably inflating vibration damping part.
The inflating vibration damping part is the air bag that two ends set connecting plate.
The air bag is arranged on the middle area and marginal zone of loading plate.The middle area and marginal zone of loading plate are arranged on, is allowed
Loading plate distribution of force is more balanced, reduces for a long time in use, being exerted a force positioned at middle gearbox and fan in the middle of loading plate
Loading plate is caused to deform.
The section of the air duct 41 is circle, increases some concentric hush pipes in air duct when noise reduction does not reach requirement
42, hush pipe 42 is connected in air duct 41, and the center of circle of hush pipe section circle is overlapped with the center of circle of air duct section circle.
In the noise reduction grid 51, in the middle of the adjacent vertical bloop of each two, some crosspiece bloops are tiltedly installed with,
Constitute the noise reduction cell that multiple sections are square.
Embodiment 3
As another design of inflating vibration damping part,
The inflating vibration damping part sets the inflated wheel of connecting shaft for centre.
The inflated wheel is arranged on the marginal zone of loading plate, the pylon or capital construction face outside loading plate and sets limiting block
Plate, keeps off outside inflated wheel.
Using inflation wheel construction, this structure is directly commercially available, such as various small-sized inflation wheels, in setting,
Inflated wheel needs the quantity set many compared with air bag, and in order to prevent wheel from rolling, capital construction face or pylon outside loading plate
Upper setting baffle plate, blocking it can not rotate, and realize spacing.So gather the structure design of wheel, can add in the middle of loading plate or
It is not added with inflated wheel.
