Description
Technical field
The utility model belongs to Fan Equipment technical field, relates to a kind of silencer of high pressure blower.
Background technique
High pressure blower, also be high pressure positive blower, its inside is provided with fan blade, in the time that fan blade rotates, due to the effect of centrifugal force, wind vane impels gas outwards motion forward, thereby form a series of spiral helicine motions, air between fan blade blade accelerates in the shape of a spiral rotation and the gas outside the pump housing is clamp-oned to side channel, after its approaching side passage, gas is compressed, then be returned to again between impeller blade and again accelerate to rotate, the degree that each impeller blade has increased compression and accelerated, along with the carrying out of rotation, the kinetic energy of gas increases, the gas pressure passing through along side canal is further increased, final gas is extruded blade and discharges the pump housing by outlet.Current high pressure blower, except impeller outer, does not have other moving parts, and the direct connecting motor of impeller, and small-sized being easy to carry about with one is widely used in cooling etc. the general suction air-supply of printing machinery, burning machine, woodworking machinery, dryer, incinerator, machinery.Because the air-flow of high pressure blower can produce a large amount of noises, therefore at the exhaust outlet place of high pressure blower, baffler all can be installed.
As Chinese invention patent application (application number: 200620074272.7) disclose a kind of silencer of blower, for blower noise reduction, it comprises airduct, inner tube and flexible packing, inner tube is set in airduct, it is characterized in that described inner tube has many, between each inner tube and between inner tube and airduct, be filled with flexible packing, each inner tube is supported in airduct by flexible packing.Although this model utility changes original single internal tube noise reduction the noise reduction of into many inner tubes, increase the area of contact between inner tube and soft sound absorbing material, strengthen sound-absorbing efficiency, if but on a blower, paper is installed an above-mentioned baffler, and its erasure effect is still limited.
Summary of the invention
There are the problems referred to above for existing technology in the utility model, has proposed a kind of silencer of high pressure blower, and the erasure effect of the silencer of this high pressure blower is better, improves the total quality of blower.
The purpose of this utility model can realize by following technical proposal: a kind of silencer of high pressure blower, comprise wind bucket and motor, the output shaft of described motor stretches into wind bucket, and the inserting end at output shaft is fixed with fan blade, on described wind bucket, offer intake grill and exhaust outlet, it is characterized in that, described silencer comprises that one is the box body of strip, on one end end face of described box body, offer intake opening, on the other end end face, offer exhaust vent, described intake opening is connected with the exhaust outlet of wind bucket, in described box body, be fixed with the dividing plate of some strips, and become several chambers by this baffle for separating, described two adjacent chambers connect, above-mentioned intake opening is connected with the chamber of box body one side, exhaust vent is connected with the chamber of box body opposite side.
Wind bucket is connected mutually with motor, the output shaft of motor stretches into wind bucket and is directly connected mutually with fan blade afterwards, can drive fan blade rotation, the air-flow of its generation is discharged from exhaust outlet, and enter in box body from intake opening, because the inner chamber of box body becomes several chambers by baffle for separating, and two adjacent chambers connect, therefore the air-flow that enters box body can form the roundabout route advancing by each chamber successively, and finally get rid of from exhaust vent, in air current flow process, air-flow can clash into and be absorbed noise, therefore good muffling effect mutually with dividing plate and inboard wall of cartridge.
In the silencer of above-mentioned high pressure blower, the cross section of described box body is fan-shaped, and described dividing plate has two, and the length direction of dividing plate is consistent with the length direction of box body, and the width direction of dividing plate is radially consistent with box body.Cross section is fan-shaped box body and can fits with motor outer surface, after box body is fixing, makes overall structure compacter.
In the silencer of above-mentioned high pressure blower, the two ends that are positioned at the chamber at box body middle part all offer vent hole, described intake opening is opened in one end of the chamber that is positioned at box body one side, the other end of this chamber offers vent hole, described exhaust vent is opened in one end of the chamber of box body opposite side, the other end of this chamber also offers vent hole, and described adjacent two vent holes are connected.Be that air-flow is entered by one end of chamber, and flow out and enter adjacent chamber from the other end, so form roundabout glide path.
In the silencer of above-mentioned high pressure blower, the two ends of described box body are all fixed with a cover plate, between described cover plate inner side surface and box body end face, form vent passages, and described adjacent two vent holes are connected by vent passages.Cover plate plays seal action to box body, changes air flow direction simultaneously, makes air-flow can enter smoothly adjacent chamber.
In the silencer of above-mentioned high pressure blower, on described cover plate inner side surface, be fixed with muffle coating.Air-flow changes the flow direction under the effect of cover plate, it can clash into cover plate, muffle coating is a sound deadening coating, main biological fiber, the mineral fibre etc. of adopting spray in conjunction with adhesive together for main raw material, being attached to baffle surface, forming the apparent cotton shape coating of concrete dynamic modulus that has, is the comparatively general antidrumming compound of a kind of use, therefore can absorb noise, improve the erasure effect of box body.
Compared with prior art, the silencer of this high pressure blower has the following advantages:
1, because the inner chamber of box body becomes several chambers by baffle for separating, and two adjacent chambers connect, therefore the air-flow that enters box body can form the roundabout route advancing by each chamber successively, air-flow can clash into and be absorbed noise, therefore good muffling effect mutually with dividing plate and inboard wall of cartridge.
2, owing to being fixed with muffle coating on cover plate inner side surface, air-flow and cover plate clash into, and muffle coating can absorb noise, improve the erasure effect of box body.
3, because the cross section of box body is fan-shaped, can fit with motor outer surface, after box body is fixing, make overall structure compacter.
