Description
Technical field
The invention belongs to and ventilate and the air purifying process field, relate in particular to a kind of low noise centrifugal wind wheel with purification function.
Background technique
Centrifugal wind wheel is widely used in ventilating and air purification field, go up a large amount of centrifugal wind wheels that use as air conditioner, air cleaner (device), for guaranteeing that centrifugal wind wheel keeps enough rigidity when the high speed rotating, wind wheel adopts high-strength engineering plastic even metallic material to make usually, so wind wheel surface hardness height, air-flow and wind wheel interior edge face and blade surface bump produces very big aerodynamic force noise when high speed rotating like this.
A kind of low noise centrifugal cutter wind wheel is disclosed among model utility ZL95219987.4 and the ZL95219986.6, it is passing through to cover one deck noise reduction layer at blade and wind wheel interior edge face, the noise reduction layer material is by being rubber or foamed plastics or chemical fibre suede or flexible PVC, and covering method can be static flocking or spraying or bonding.This method reduces noise result clearly but exist obviously not enough, be that the fan wind wheel is after operation a period of time, because air friction produces static, the attached collection of dust in air particle is on the wind wheel surface, cause the wind wheel operating load to strengthen, wind wheel loses dynamic balancing and wind wheel operation noise is gone up not down, and can not keep noise reduction, wind wheel does not have purifying functions yet, has influenced the application of this model utility.
Summary of the invention
The objective of the invention is to the above problem, a kind of low noise centrifugal wind wheel with purification function of giving the effect of wind wheel to purify fresh air in lasting maintenance wind wheel noise reduction is provided at existing centrifugal wind wheel existence.
The object of the present invention is achieved like this: the present invention is coated with the elastomeric paint coating that one deck has silencing function on the surface of centrifugal wind wheel, and described elastomeric paint coating is elastic caoutchouc lacquer coating or elasticity fine hair lacquer coating, and the thickness of elastomeric paint coating is the 1-100 micron; Also scribble one deck nano-photo catalytic coating on the surface of elastomeric paint coating, the thickness of nano-photo catalytic coating is the 0.01-100 micron.
Elastomeric paint coating among the present invention is used for noise reduction.Elastic rubber paint or elasticity fine hair lacquer are the paint that a class can form certain elasticity paint film, it can be that one-component also can be two components, can be solvent borne also can be the paint of water-based, best results be the elastic polyurethane rubberbase paint or the elasticity fine hair lacquer of two components.The thickness of elastomeric paint coating is preferably the 10-40 micron.
As preferred version, described nano-photo catalytic coating is nano titanium dioxide photocatalysis coating or its rare earth doped modifier coating.The nano titanium dioxide photocatalysis coating particularly excites behind the ultraviolet and is adsorbed on the airborne oxygen molecule of catalyst surface and water molecule and forms active group absorbing luminous energy, have high chemically active active group and decompose the surface tension that the organic chemicals that is adsorbed on the wind wheel surface reduces wind wheel simultaneously fast, can prevent that like this dust granule is at the attached collection in wind wheel surface, the cleaning that keeps the wind wheel surface, the dynamic balancing that has kept wind wheel, guarantee the long-term good running state of wind wheel, thereby keep the lasting noise reduction of wind wheel, give wind wheel certain effect that purifies air simultaneously.
Described nano titanium dioxide photocatalysis coating can adopt hydrosol type or solvent-borne type nano titanium oxide as coating, described hydrosol type nano titanium oxide is to be precursor, to be medium with water, to be the titanium dioxide aqueous dispersion of dispersing aid with the surface active agent with the titanate ester compound, described solvent-borne type nano titanium oxide is to be precursor, to be that medium is the titanium dioxide dispersion of dispersing aid with the surface active agent with the alcohol equal solvent with the titanate ester compound, the weight percentage of titanium dioxide is 0.1-20% in above-mentioned coating, preferred 1-1.5%.The thickness of nano-photo catalytic coating is preferably the 0.1-10 micron.
In order further to improve the purifying property of wind wheel, the present invention is in elastomeric paint coating and/or nano-photo catalytic coating, promptly in the elastomeric paint coating or in the nano-photo catalytic coating or simultaneously in elastomeric paint coating and nano-photo catalytic coating, also be mixed with anion-generating material, the incorporation of anion-generating material in each coating is 0-95% by weight percentage, is preferably 1%-20%.Described anion-generating material is tourmaline, holder morpholine stone, germanite or its composite etc.Like this wind wheel in the running anion-generating material constantly discharge negative ion, thereby improve airborne anion concentration, eliminate airborne positive charge and positively charged particulate matter, reach the purpose that purifies fresh air.
Technique effect of the present invention is: the present invention can keep the lasting noise reduction of wind wheel, gives the effect that wind wheel purifies air simultaneously.The present invention can be widely applied on purification and the ventilation plant, noise-decreasing and energy consumption.
The invention will be further described below in conjunction with drawings and Examples.
