Description
The utility model relates to the flexible silencer of the ventilation equipment of the silencer of the ventilation equipment of industrial use, particularly mine, tunnel or the use of other industrial department.
The ventilation equipment of industrial use, in general noise is very big, and the JBT profile shaft streaming ventilating fan of using as mine (abbreviation portable blower) can produce 105～120 decibels heat-flash noise.People have developed various silencer for this reason, as the tapered portable blower silencer of circular shape, Z type and microperforated panel.The sound deadening capacity of these silencer and drag losses, still can meet the demands at the use initial stage, but, because the dust under the mine is big, high humidity, sound-absorbing material is perishable, the perishable damage of micropore the phenomenon that sound deadening capacity descends even scraps generally will occur after half a year, so its application is restricted.
Present comparatively approaching prior art is as Chinese patent CN85204510 and the 21st page of disclosed silencer of 1985 the 10th phases " labor protection " magazine.The former is made up of base, inside and outside hush tube, end cap, core frame and aluminium or the netted guard shield of steel, is mainly used in specific occasions; The latter is by joint flange, outer hush tube, noise elimination stem stem and stationary links thereof, the netted guard shield of steel and shell, and aerofoil profile guide flow noise elimination sheet, composition such as water spray purification plant etc.Because the netted guard shield of existing silencer and shell normally adopt sheet metal to make, therefore when humidity is used with the occasion that steam is arranged, corrosion even hole occurs gets rusty easily, it is very big to offset the sound effective value influence, when the silencer of this structure of while, its sound-absorbing material used in the many occasions of dust, the very fast micropore sound-absorbing material of dust blocked, it is very big that its acoustic absorptivity is descended, and plays sound absorption hardly.Steel shell weight is big in addition, and volume is also big, is unfavorable for moving and carrying not vibration isolation simultaneously.
The utility model has very been done improvement to the problem of above-mentioned existence, provide a kind of volume little, in light weight, rational in infrastructure, be convenient to loading and unloading, sound-absorbing material is replaceable, simultaneously, both noise attenuation, the flexible silencer of collapsible compression again effectively.The utility model is achieved in the following way: a kind of flexible silencer, comprise shell, outer hush tube and on armour layer, the noise elimination stem stem and on armour layer and the connecting rod that is used for fixing the noise elimination stem stem, joint flange, end flange etc., shell of the present utility model, be to adopt by metal spring, the igelite of metal-containing element, the collapsible compression that high-intensity fibre cloth and graphite etc. are formed is the soft shell of sound insulation again, wherein metal spring is made skeleton, the igelite of filling metal-containing element, behind high-intensity fibre cloth and the graphite, bonding or once hot-forming through adhesive, promptly become the soft shell of collapsible compression.This shell acid resistant alkali, the mechanical strength height has the effect of expanding with heat and contract with cold with the sound insulation vibration isolation that compensates simultaneously.Also have antistatic and age inhibiting effect in addition.
Said shell is provided with a suspension gear of being made up of supporting ring and last several uniform suspension ring thereof along its radial circumference surface, wherein suspension ring can be three, also can be six.The main effect of this mechanism is to be convenient to install.
Said shell is provided with an expansion regulating mechanism of being made up of adjustable lever I, adjustable lever II, loose-proof sleeve and fixing pin along its axial circumferential surface, its volume that is mainly used in flexible silencer reduces, so that carrying also has the effect of reinforcing and supporting soft shell simultaneously.
Armour layer on said outer hush tube and the noise elimination stem stem by covering fabric and on the mask film and the support spring that play supporting role form, the stem stem of wherein eliminating the noise is made the cylindrical body or the cone of cavity, corresponding support spring is arranged in the cavity.Outer hush tube and noise elimination stem stem can adopt existing various sound-absorbing material, its armour layer can adopt the mask film on covering fabric and the Tu Duqi and use support spring fixed-type, to replace original covering fabric and protection slab (perforated plate), so both can play the corrosion resistant effect of dustproof and waterproof, collapsible again compression.After outer in addition hush tube and noise elimination stem stem adopted this structure, it was also very convenient to install and change.
The utility model is compared with prior art, because shell, outer hush tube and noise elimination stem stem all are flexible, therefore have collapsible compression, volume little, in light weight, be convenient to carry, the long service life of sound-absorbing material and characteristics such as replaceable, have simultaneously that compensation is expanded with heat and contract with cold, sound insulation vibration isolation and antistatic, age inhibiting characteristics.
