Upper acoustic filter B uses aluminum starframe to support, and by vibration isolator 25, (rubber hinders with the starframe of reactor body
Buddhist nun's device) connect fastening；Connect fastening and use austenitic stainless steel bolt 22；Rubber cushion assembly can completely cut off the vibration of reactor body
Passing to acoustic filter B, austenitic stainless steel is non-magnet material；
The smoothing reactor that umbrella A, upper acoustic filter B, body acoustic hood C, lower acoustic filter D from top to bottom form efficiently drops
The system of making an uproar is integral rigidity structure, this structure only on upper acoustic filter B starframe position and reactor starframe pass through vibration isolator
25 connect (being only connected with smoothing reactor body 12) by vibration isolator 25, and remaining position is all without rigid contact, it is ensured that vibration
This noise reduction system cannot be passed to.
Inside upper acoustic filter, fill straight plate anechoic sheet, sound deadening capacity can be made to reach more than 15dB, simultaneously on the top of upper acoustic filter
Umbrella is installed in portion, sound deadening capacity can be made further up to more than 18dB；This utility model is filled straight plate inside lower acoustic filter and is disappeared
Sound sheet, can make sound deadening capacity reach more than 20dB.Three kinds of structures that body acoustic hood uses are respectively as follows: modified glass cotton sound absorption+sound insulation
Plate, microwell plate+glass cotton+sound insulationg board, sound insulationg board；The oise insulation factor of three kinds of structures is followed successively by 25dB, 30dB, 20dB.Survey through reality
Amount, test under power frequency, tetra-kinds of operating modes of 75Hz, 150Hz, 200Hz, the body acoustic hood of three kinds of structures with " umbrella, on
Lower acoustic filter " noise reduction system that forms, finally it is followed successively by through being scaled A weighted sound pressure level noise reduction: 15dB, 18dB and 14dB.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, all in this utility model power of awaiting the reply
Within the scope of profit is claimed.
