Abstract
The invention discloses a silent fan of a xylene distilling machine. The silent fan of the xylene distilling machine comprises a drive motor, wherein a rotary head is arranged on the drive motor rotationally; three fan blades are arranged on the periphery of the rotary head; the periphery of each fan blade is provided with a damping periphery; the damping peripheries are provided damping tail tips; the damping peripheries are made of plastics. As the damping peripheries are arranged on the peripheries of the fan blades and the damping tail tips are arranged on the damping peripheries, vibration can be absorbed to the maximum extent in the rotation process of the fan, and noise is greatly lowered.
Description
Technical field
The present invention relates to a kind of fan, or rather, is a kind of dimethylbenzene distilling machinery quiet fan.
Background technique
Dimethylbenzene distilling machinery is widely used in the industrial production, but the fan noise of the dimethylbenzene distilling machinery generally used at present is larger.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus the dimethylbenzene distilling machinery quiet fan providing a kind of noise little.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of dimethylbenzene distilling machinery quiet fan, comprise a drive motor, described drive motor is provided with a swivel head rotationally, some flabellums are arranged with at the outer of described swivel head, respectively be provided with a noise elimination in the periphery of described flabellum peripheral, place outside described noise elimination and be also provided with a noise elimination tail point.
As preferred embodiment of the present invention, the quantity of described flabellum is 3.
As preferred embodiment of the present invention, described noise elimination periphery is made of plastics.
Because dimethylbenzene distilling machinery quiet fan of the present invention is provided with in the periphery of flabellum periphery of eliminating the noise, and be provided with noise elimination tail point outer the placing of noise elimination, in the process of fan turns, such arranging can absorb vibration to greatest extent, thus greatly reduces the generation of noise.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of dimethylbenzene distilling machinery quiet fan of the present invention;
Fig. 2 is the perspective view of the dimethylbenzene distilling machinery quiet fan in Fig. 1, is now another visual angle.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The invention provides the dimethylbenzene distilling machinery quiet fan that a kind of noise is little.
As shown in Figure 1 and Figure 2, a kind of dimethylbenzene distilling machinery quiet fan 1, comprise a drive motor 21, described drive motor 21 is provided with a swivel head 22 rotationally, some flabellums 3 are arranged with at the outer of described swivel head 22, respectively be provided with a noise elimination periphery 4 in the periphery of described flabellum 3, described noise elimination periphery 4 be also provided with a noise elimination tail point 5.
As shown in Figure 1 and Figure 2, the quantity of described flabellum 3 is 3.
As shown in Figure 1 and Figure 2, described noise elimination periphery 4 is made of plastics.
The dimethylbenzene distilling machinery quiet fan of this invention is provided with periphery of eliminating the noise in the periphery of flabellum, and be provided with noise elimination tail point outer the placing of noise elimination, in the process of fan turns, such arranging can absorb vibration to greatest extent, thus greatly reduces the generation of noise.
Below only in one embodiment mentality of designing of the present invention is described, when system allows, the present invention can expand to external more function module simultaneously, thus expands its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
