Abstract

The utility model discloses a kind of air inlet noise-reducing structures of magnetic suspension blower, magnetic suspension blower is placed in cabinet, air inlet is equipped on four sides of cabinet, it further include soundproof plate, several soundproof plates are uniformly distributed along the circumferencial direction of air intake duct in magnetic suspension blower, and the both ends of soundproof plate are fixed in cabinet, soundproof plate is located at the inside of air inlet.The utility model uses radial circular arc soundproof plate noise reduction by the center of circle of air inlet passage center, to reduce flow resistance, noise is reduced, when magnetic suspension blower starts, extraneous gas enters interior of equipment cabinet by the air inlet of cabinet, enters air intake duct using the silencing cavity between internal radiation shape circular arc soundproof plate.Since soundproof plate uses arcuate structure, the resistance of air-flow can be reduced and then the noise of gas flowing can be reduced, since soundproof plate uses the structure of surface porous metal plate and internal silencing cotton, some high frequency noises spread out of inside host can also be eliminated.

Description

A kind of air inlet noise-reducing structure of magnetic suspension blower
Technical field:
The utility model relates to a kind of air inlet noise-reducing structures of magnetic suspension blower.
Background technique:
Existing magnetic suspension centrifugal blower mainly uses sound-insulating covering structure by host air intake duct and air inlet part Noise reduction is separated, existing soundproof plate is vertically or horizontally to design mostly, and flow direction changes greatly when air-flow passes through baffle, and flow resistance is larger, Noise is easy to produce in the place that air flow direction changes greatly.
Utility model content:
The utility model is to provide a kind of air inlet of magnetic suspension blower to solve the above-mentioned problems of the prior art Noise-reducing structure.
Technical solution used by the utility model has: a kind of air inlet noise-reducing structure of magnetic suspension blower, including cabinet and Magnetic suspension blower, the magnetic suspension blower are placed in cabinet, and cabinet is rectangular structure, are equipped on four sides of cabinet Air inlet further includes soundproof plate, several soundproof plates are uniformly distributed along the circumferencial direction of air intake duct in magnetic suspension blower, and phase Silencing cavity is formed between adjacent two soundproof plates, silencing cavity is connected with air inlet, and the both ends of soundproof plate are fixed in cabinet;
The soundproof plate is convex structure, including Inner arc orifice plate, external arc orifice plate, intermediate silencing cotton and end plate, institute It states Inner arc orifice plate and external arc orifice plate is arranged in parallel, and formed between filling between Inner arc orifice plate and external arc orifice plate Gap, intermediate silencing cotton are filled in the filling gap, and end plate is fixed on the surrounding of inside and outside circular arc orifice plate and will filling gap envelope It closes.
Further, it is fixedly connected with connection sheet on the outer wall of the soundproof plate, fixation hole is equipped in connection sheet.
Further, the air inlet is equipped with strainer.
The utility model has the following beneficial effects: the utility model uses radial circular arc by the center of circle of air inlet passage center Soundproof plate noise reduction reduces noise to reduce flow resistance, and when magnetic suspension blower starts, extraneous gas enters by the air inlet of cabinet Interior of equipment cabinet enters air intake duct using the silencing cavity between internal radiation shape circular arc soundproof plate.Since soundproof plate uses arc Structure can reduce the resistance of air-flow and then can reduce the noise of gas flowing, since soundproof plate uses surface porous metal plate With the structure of internal silencing cotton, some high frequency noises spread out of inside host can also be eliminated.
Detailed description of the invention:
Fig. 1 is the utility model structure chart.
Fig. 2 is the structure chart of soundproof plate in the utility model.
Specific embodiment:
The utility model will be further described below with reference to the accompanying drawings.
Such as Fig. 1 and Fig. 2, a kind of air inlet noise-reducing structure of magnetic suspension blower of the utility model, including cabinet 1, magnetic suspension wind Machine 2 and soundproof plate 3.
Magnetic suspension blower 2 is placed in cabinet 1, cabinet 1 be rectangular structure, be equipped on four sides of cabinet 1 into Air port 11, several soundproof plates 3 are uniformly distributed along the circumferencial direction of air intake duct 21 in magnetic suspension blower 2, and adjacent two sound insulation Silencing cavity 30 is formed between plate 3, silencing cavity 30 is connected with air inlet 11.The both ends of soundproof plate 3 are fixed in cabinet 1, sound insulation Plate 3 is located at the inside of air inlet 11.
Soundproof plate 3 is convex structure, including Inner arc orifice plate 31, external arc orifice plate 32, intermediate silencing cotton 33 and end plate, Inner arc orifice plate 31 and external arc orifice plate 32 are arranged in parallel, and are formed and filled out between Inner arc orifice plate 31 and external arc orifice plate 32 Gap is filled, intermediate silencing cotton 33 is filled in the filling gap, and end plate is fixed on the surrounding of inside and outside circular arc orifice plate and will filling Gap closing.
For the fixed installation convenient for soundproof plate 3, connection sheet 34 is fixedly connected on the end plate of bottom surface in soundproof plate 3, Connection sheet 34 is equipped with fixation hole.Soundproof plate 3 is fixed by bolts on cabinet 1 and magnetic suspension blower 2.
Strainer is equipped at air inlet 11.
The utility model uses radial circular arc soundproof plate noise reduction by the center of circle of 21 center of air intake duct, to reduce flow resistance, drop Low noise, when magnetic suspension blower 2 starts, extraneous gas enters interior of equipment cabinet by the air inlet 11 of cabinet, using internal spoke The silencing cavity 30 penetrated between shape circular arc soundproof plate 3 enters air intake duct.Since soundproof plate uses arcuate structure, air-flow can be reduced Resistance can reduce the noise of gas flowing in turn, since soundproof plate uses the structure of surface porous metal plate and internal silencing cotton, The some high frequency noises spread out of inside host can also be eliminated.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as The protection scope of the utility model.
