Description
Technical field
This utility model belongs to sound insulation and noise reduction technical field, is specifically related to a kind of high pressure positive blower denoising device.
Background technology
Industrial blower fan is the equipment continuously run, and the noise given off during fan operation, up to 100 decibels, especially goes out
The high pressure positive blower that mouth pressure is higher, turn up 15000 to 30000 turns is bigger to extraradial noise during operating.During fan operation
The intense noise produced severely impacts the peace and quiet of surrounding enviroment, normal communication contact and the friendship of language in not only hindering workshop
Talk, bring certain impact to safety in production；And the generation of attending class doing work and school to the rest of surrounding resident, office is tight
The interference of weight.The main harm of strong noise on human body not only damages auditory system, and serious also can affect linguistic competence.As
Fruit does not use noise countermeasure, and fan noise can substantially exceed the requirement of acoustic environment standard, and therefore denoising device is the actual fortune of blower fan
Device indispensable in row.
Fan noise is mainly made up of three parts, and one is intake stack vibration noise, two is motor running noises, three is high
Speed exhaust noise.In actual use, the air vent of blower fan is expelled to corresponding pipeline, air inlet/outlet pipeline after often accessing acoustic filter
Also major part does silencing cotton protection, but noise of motor is the biggest, if simply at height plus the noise produced that runs up
Using seal bootr to carry out sound insulation and noise reduction outside pressure fan, the higher temperature of high pressure positive blower discharge gas can make the operation of high pressure positive blower
Environment heats up, and causes motor temperature rise rising, operational efficiency to reduce, and therefore pole is necessary to consider the overall sound insulation of design outside blower fan
Device, carries out sound insulation and noise reduction process, preferably to reduce noise of equipment to inner and outer ring in the case of ensureing motor running environment
The pollution in border.
Utility model content
This utility model aims to provide the high pressure positive blower fall of misconstruction around constituting between a kind of intake and exhaust
Make an uproar device technique scheme, to overcome problems of the prior art.
Described high pressure positive blower denoising device, the motor of high pressure positive blower and main frame are in front and back's arrangement, it is characterised in that
Being equipped with enclosed blimp outside high pressure positive blower, on the blimp lower cover wall of the motor left and right sides, a relative set left side is entered
Air regulator, right air-inlet window, the blimp above main frame connects and arranges ventilation fan.
Described high pressure positive blower denoising device, it is characterised in that the cover wall of described blimp uses multi-layer compound structure,
It is equipped with deadener layer between outer layer plate and internal layer steel plate with holes.
Described high pressure positive blower denoising device, it is characterised in that described left air-inlet window, right air-inlet window are symmetricly set on electricity
Machine both sides.
Described high pressure positive blower denoising device, it is characterised in that described blimp uses removable full-closed structure, by
Skeleton and window blimp wall are spliced to form.
Above-mentioned high pressure positive blower denoising device, novel, simple and reasonable, have that sound insulation and noise reduction is effective, unit
Operational efficiency high, before and after the motor of left air-inlet window, right air-inlet window high pressure positive blower corresponding with ventilation fan, main frame use, left
Dextroposition is arranged, the fresh air air-inlet window from motor both sides enters, and the ventilation fan above main frame is discharged, constitute air inlet with
The air flow structure of dislocation around between aerofluxus, makes the space between blimp internal sound insulation cover and high pressure positive blower constitute and is formed
From bottom to top, from front air convection channel then, while realizing sound insulation and noise reduction, reduce high pressure positive blower running environment temperature
Degree, it is achieved that weaken displacement noise, reduce motor operation temperature rise, the beneficial effect of raising motor operational efficiency.

Detailed description of the invention
In conjunction with Figure of description, describe detailed description of the invention of the present utility model in detail:
As shown being high pressure positive blower denoising device, the motor 4b and main frame 4a of high pressure positive blower 4 are in front and back's arrangement, high
Pressure fan 4 is outside is equipped with enclosed blimp 1, and the cover wall of blimp 1 uses multi-layer compound structure, and outer layer plate is with interior
Being equipped with deadener layer between layer steel plate with holes, the aperture on internal layer steel plate with holes constitutes sound absorption passage, makes blimp 1
Have and preferably inhale effect of making an uproar, completely cut off the partial noise that high pressure positive blower outwards discharges, decreased the pollution of Noise upon Environment, be
The effective measures of noise are controlled at sound source.Left air-inlet window 5, the right side are set on the blimp 1 lower cover wall of the motor 4b left and right sides
Air-inlet window 2, left air-inlet window 5, right air-inlet window 2 are symmetricly set on motor 4b both sides, the blimp 1 above main frame 4a connect and arranges
Ventilation fan 3, fresh air enters from left air-inlet window 5, right air-inlet window 2, utilize space between blimp 1 and high pressure positive blower 4 from
Flowing toward top in bottom, discharges from ventilation fan 3, defines and constitute mistake around between intake and exhaust in blimp 1
The air flow structure of position, takes away the heat that the operating of blimp 1 inner high voltage blower fan 4 produces, can effectively reduce the operation ring of high pressure positive blower 4
Border temperature, reduces the temperature rise of motor 4b and the operational efficiency improving motor 4b.
In above-described embodiment, blimp 1 uses removable full-closed structure, skeleton and window blimp wall splice structure
Becoming, some skeletons and window blimp wall are spliced, this dismountable structure is conducive to the transport of denoising device, installation,
It is also convenient for the operation of high pressure positive blower, overhauls and safeguard.
