Abstract
The invention discloses a low-noise ventilator which comprises a housing, wherein a base is mounted at the bottom end of the housing; a ventilation opening is formed in the base; an impeller and a motor are arranged in the housing; the impeller is mounted at the bottom end of the motor; a noise-reduction housing is mounted outside the motor; an air outlet is formed in the top end of the housing; and a filter screen is arranged at the air outlet. The low-noise ventilator has the following beneficial effects: the low-noise ventilator is simple in structure, small in size, convenient to maintain and convenient to operate and use; by adopting a double-layer housing structure, the low-noise ventilator can greatly reduce noise pollution, doesn't affect the working environment of workers and meanwhile is improved in stability; and an arranged heat dissipation layer can effectively prevent a motor overheating phenomenon and has high stability performance.
Description
Technical field
The present invention relates to a kind of ventilation blower, particularly relate to a kind of low noise ventilator.
Background technology
Ventilation blower is a kind of plant equipment having a large capacity and a wide range, and is widely used in the industrial circles such as energy source and power, petrochemical industry, metallurgy and all kinds of naval vessel of military project.Impeller is rotary part, rotary centrifugal force and air-flow power that bias causes will make impeller produce vibration, volute of blower belongs to thin-walled pressure vessel structure, the pressure fluctuation that the flowing of gas and the interaction of spiral case wall are formed will make spiral case produce bigger vibration radiated noise, affecting work and rest, the reduction service life of equipment of erect-position personnel, vibration is transferred to equipment mounting feet will affect stability.
Therefore, for solving the problems referred to above, a kind of new technical scheme of special offer.
Summary of the invention
The present invention provides a kind of low noise ventilator.
The technical solution used in the present invention is:
A kind of low noise ventilator, including housing, described housing bottom is provided with base, described base has vent, being positioned at enclosure interior and be provided with impeller and motor, described motor bottom is provided with impeller, is provided with noise-reduction case in the outside of motor, the top of described housing is provided with air outlet, is provided with filter screen at air outlet place.
Further, described housing is ellipticity.
Further, it is provided with heat dissipating layer inside described noise-reduction case.
Further, it is connected by bracing frame is fixing between described noise-reduction case and housing.
Further, space is left between described impeller and noise-reduction case.
Further, the diameter of described impeller is less than the diameter of vent.
The invention has the beneficial effects as follows: simple in construction, volume is little, easy to maintenance, easy for operation, adopt the version of double Shell, sound pollution can be substantially reduced, do not affect the working environment of staff, improve the stability of ventilation blower simultaneously, the heat dissipating layer of setting, effectively preventing the appearance of motor overheating phenomenon, stability is high.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is the structural representation of the present invention.
Wherein: 1, housing, 2, base, 3, vent, 4, impeller, 5, motor, 6, noise-reduction case, 7, air outlet, 8, heat dissipating layer, 9, bracing frame, 10, filter screen.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment is only used for explaining the present invention, is not intended that the restriction to protection scope of the present invention.
A kind of low noise ventilator as shown in Figure 1, including housing 1, housing 1 bottom is provided with base 2, having vent 3 on base 2, be positioned at housing 1 inside and be provided with impeller 4 and motor 5, motor 5 bottom is provided with impeller 4, in the outside of motor 5, noise-reduction case 6 is installed, the top of housing 1 is provided with air outlet 7, is provided with filter screen 10 at air outlet 7 place, and housing 1 is in ellipticity；
Noise-reduction case 6 is internal is provided with heat dissipating layer 8, is connected by bracing frame 9 is fixing, fixation between noise-reduction case 6 with housing 1；
Leaving space between impeller 4 and noise-reduction case 6, the diameter of impeller 4, less than the diameter of vent 3, improves stablizing effect and performance of ventilating.
The invention has the beneficial effects as follows: simple in construction, volume is little, easy to maintenance, easy for operation, adopt the version of double Shell, sound pollution can be substantially reduced, do not affect the working environment of staff, improve the stability of ventilation blower simultaneously, the heat dissipating layer of setting, effectively preventing the appearance of motor overheating phenomenon, stability is high.
The above, be only presently preferred embodiments of the present invention, is not the restriction that the present invention makees any other form, and any amendment that the technical spirit of the foundation present invention is made or equivalent variations, still fall within present invention scope required for protection.
