Abstract
The utility model relates to a blower, comprising a shell, an impeller installed at the inner cavity of the shell, and a motor for driving the impeller to rotate, wherein the shell is provided with a wind inlet and a wind outlet. The blower is characterized in that silencing cotton is wrapped on the outer surface of the shell; and a first through hole communicated with the wind inlet and a second through hole communicated with the wind outlet are formed on the silencing cotton. The silencing cotton has the characteristics of low heat conductivity, good sound absorption performance, no combustion, corrosion resistance and the like, so that the silencing cotton can play a part in sound absorption and heat insulation; therefore, the blower has relatively strong thermal insulation ability, and can keep good heat preservation and heat insulation effects; and synchronously, the silencing cotton has excellent damping performance so that noise produced in the operation process of the blower can be reduced.
Description
Technical field
The utility model relates to a kind of air exhausting device, relates in particular to a kind of blower fan.
Background technique
Blower fan more or less all can produce vibrations in the course of the work, especially for industrial blower fan, general because power is big and volume is comparatively huge, vibrations are particularly evident under the impact of crossing flow medium, vibrations both can bring bigger noise, had a strong impact on the working life of blower fan again.In addition, blower fan is in running, and the heat of crossing flow medium very easily is delivered to the casing housing of blower fan, cause casing surface temperature higher on the one hand, scald the field personnel easily, make blower fan effectively to be incubated on the other hand, and then have influence on the working efficiency of blower fan crossing flow medium.The multiple blower fan that can be incubated thermal insulation is also arranged in the prior art, as the patent No. is that the Chinese utility model patent of CN200920115272.0 (notice of authorization number for CN201368038Y) discloses a kind of high temperature centrifugal blower, it comprises housing, impeller, motor and transmission shaft, described housing comprises front side plate, back side panel and coaming plate, on front side plate, be provided with intake grill, described impeller is provided with axle sleeve, and described motor and impeller are in transmission connection by transmission shaft and axle sleeve; The end face of described transmission shaft and axle sleeve joint is provided with thermal shield, and described thermal shield covers the end of transmission shaft and the close intake grill direction of axle sleeve.Because the end face of transmission shaft and axle sleeve joint is provided with thermal shield, thermal shield covers the end of transmission shaft and the close intake grill direction of axle sleeve again, so just effectively avoided transmission shaft and axle sleeve to be subjected to the influence of high-temperature gas and temperature sharply raises, thereby heat is delivered to bearing by transmission shaft, makes bearing temperature too high and influence the ride quality and the working life of blower fan.But this model utility has just effectively been protected transmission shaft and axle sleeve, still is difficult to avoid housing because being subjected to heat transmits and cause surface temperature too high, and the method for this set thermal shield is to reducing vibrations in the fan operation process without any effect.
The model utility content
Technical problem to be solved in the utility model is at above-mentioned prior art, provides a kind of good muffling effect to have the blower fan of better insulation insulation effect simultaneously again.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this blower fan comprises casing, is installed in the impeller and the energy impeller motor rotating of chassis cavity, described casing is provided with intake grill and exhaust outlet, it is characterized in that: described casing outer surface is enclosed with the noise reduction cotton, has first through hole that communicates with aforementioned intake grill and second through hole that communicates with aforementioned exhaust outlet on the described noise reduction cotton.
As improvement, the cotton outer surface of described noise reduction is enclosed with the protection housing.Like this, can play better noise reduction and function of heat insulation.
Further improve, cotton assembly is fastening forms by being block a plurality of noise reductions for described noise reduction cotton.Like this, when the noise reduction cotton is installed, only need the cotton assembly of noise reduction one by one to be bolted together, very convenient, and also for the noise reduction cotton of integrative-structure, this assembled noise reduction cotton can make full use of material, saves manufacture cost.
Further improve, described blower fan also comprises a frame, and described casing and motor all are fixed on the frame.The general volume of industrial blower fan is bigger, effectively damping after fixing by frame.
Compared with prior art, advantage of the present utility model is: this blower fan is enclosed with the noise reduction cotton at casing outer surface, the noise reduction cotton has that thermal conductivity is low, sound absorbing capabilities good, performance such as do not burn, corrosion-resistant, it can play good noise reduction and heat insulating function, make blower fan possess stronger heat resistanceheat resistant radiating capacity, no matter operation all can keep good insulation and effect of heat insulation in high temperature or low temperature environment; Simultaneously, the noise reduction cotton is used in also has very excellent shock absorbing characteristics on the blower fan, reduce the noise that produces in the fan operation process.

Fig. 2 is the partial sectional view of Fig. 1;
Fig. 3 is the structural representation figure after the casing among Fig. 1 is opened;
Fig. 4 is the cotton structural representation that splits after coming of noise reduction among Fig. 3.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figures 1 to 4, the motor (not shown) of this blower fan and casing 1 all are fixed on the frame 5, and the impeller (not shown) is fixedly mounted on casing 1 inner chamber, and the output shaft of motor is connected on the impeller, and impeller is positioned at casing 1 inner chamber.Be wrapped in noise reduction cotton 2 at casing 1 outer surface, galvanized sheet iron is wrapped again as protection housing 4, to play better noise reduction and function of heat insulation in cotton 2 outsides of noise reduction.Wherein noise reduction cotton 2 is fixedly formed by cotton assembly 3 assembly units of noise reduction that the polylith shape differs, and with respect to the noise reduction cotton of integrative-structure, this assembled noise reduction cotton 2 had both made full use of material, had saved manufacture cost.On casing 1, be provided with intake grill 6 and exhaust outlet 7, on noise reduction cotton 2, have first through hole 8 that communicates with intake grill 6 and second through hole 9 that communicates with exhaust outlet 7, can guarantee that like this blower fan crosses the smooth circulation of flow medium.
The noise reduction cotton 2 that present embodiment adopted has that thermal conductivity is low, sound absorbing capabilities good, and performance such as do not burn, corrosion-resistant by the noise reduction cotton 2 in casing 1 this specific character of outer wrapping, can be improved the working environment of blower fan greatly.
The utility model can have multiple modification not only for above-mentioned mode of execution in this specification scope of disclosure.All adopt the equivalent technologies means to replace the technological scheme that realizes and all are regarded as in the protection domain of the present utility model.
