Description
Technical field
The invention belongs to environmental protection facilities, and in particular to a kind of fog gun silencing means.
Background technique
With atmosphere pollution be on the rise and raising of the people to habitation environment quality requirement, country is also further to ring
Guarantor is strictly administered, and the flour dust overflow of the generations such as major coal yard and each metropolitan removal, floating are got worse, in improvement
In method, commonly using this dust falling device adjustable, effect is good, high-efficient of fog gun, play to a certain extent really
Depositing dust effect.But fog gun can generate biggish noise pollution in use, to cause the noise pollution of environment, give
Office around, resident, school etc. sensitizing range exert a certain influence.
Summary of the invention
In order to reduce fog gun noise, the present invention provides a kind of fog gun silencing means.
A kind of fog gun silencing means, including tail portion silencing means, cylinder sound-absorbing material, cylinder sound insulation vibration-absorptive material, cylinder
Outside plate.The tail portion of power section is arranged in the tail portion silencing means；The cylinder sound-absorbing material is tightly attached on water conservancy diversion drum outer wall；
The cylinder sound insulation vibration-absorptive material is close to cylinder sound-absorbing material；The hull plating is wrapped on the outside of sound insulation vibration-absorptive material.
Noise in guide shell reduces noise energy by the friction of the cylinder sound-absorbing material, is a flat；
Sound after flat hinders the relative motion of object using the sound insulation vibration-absorptive material, and kinergety is changed into heat
Can, it is secondary flat；
Noise after secondary flat is decayed along the radial transmitting vibration of the sound insulation vibration-absorptive material, and it is attached to weaken resonant frequency
Close vibration, to reduce vibration；
The hull plating not only separates noise, and plays beautiful effect；
The tail portion silencing means, the ventilating noise reduction item of the different length equipped with multiple matrix arrangements, noise is wherein
By multiple reflection, collision, expansion, cooling and reduce its pressure, mitigate vibration and energy；
The ventilating noise reduction item includes sound-absorbing material, outside plate with holes；Filling sucting sound material in the space that outside plate with holes surrounds,
Sound-absorption hole ordered arrangement on the outside plate with holes.
The cylinder sound-absorbing material, sound-absorbing material are the mashed up of mineral wool or rock wool or mineral wool and rock wool；
The sound insulation vibration-absorptive material is damping sheet.
The tail portion ventilating noise reduction device includes that tail portion sound-absorbing material, tail portion sound insulation vibration-absorptive material, buttock planking, tail portion are logical
Wind noise elimination item；The tail portion absorbent treatment is wrapped on the outside of the tail portion sound insulation buffer layer, and the tail portion sound insulation buffer layer is wrapped in
On the outside of buttock planking.Three layers of closely knit ordered arrangement play the role of damping of insulating against sound；
The tail portion ventilating noise reduction device is arc；Reflection efficiency height, good appearance is arranged in arc, and the tail portion ventilation disappears
Sound matrix arrangement, noise can mitigate vibration and energy by repeatedly transmitting, collision, expansion, cooling and reduce pressure.
The cylinder sound-absorbing material can be reduced energy when noise and the friction；Institute is utilized through the reduced sound
It states tail portion sound insulation vibration-absorptive material damping sheet and hinders the relative motion of object, and kinergety is changed into thermal energy；Disappear by reduction
The noise of sound is decayed along the radial transmitting vibration of tail portion sound insulation vibration-absorptive material, and weakens the vibration near resonant frequency, from
And reduce vibration.
Detailed description of the invention
