Abstract
The utility model belongs to mechanical and electrical products and particularly relates to a noise enclosure for a Roots blower used in industrial production. The technical scheme includes that the noise enclosure comprises the Roots blower and a noise enclosure body covered around the Roots blower and is characterized in that an air inlet ventilating fan and an air outlet exhaust fan are arranged on the noise enclosure body. The noise enclosure has the advantages that when the Roots blower is started, the exhaust fan is started simultaneously, therefore cross-ventilation is achieved inside the noise enclosure, the temperature in the noise enclosure is reduced, the service life of the Roots blower is prolonged, and the noise enclosure is simple in structure and practical.
Description
Technical field
The utility model relates to dynamo-electric field, especially relate to the sound-insulating cover that is used for Roots blower that in industrial production, uses.
Background technique
The Roots blower application is very extensive, still, produces higher noise in the Roots blower running, therefore needs to be equipped with sound-insulating cover, reduces noise by the method for blocking sonic transmissions.Sound-insulating cover is generally to adopt one of method that prevents noise thus.
In the prior art, known technology is that sound-insulating cover is built up by soundproof material, be the space of relative closure, blower places in the sound-insulating cover, and is provided with a venetian blind at sound-proof shield wall, be used for the air natural circulation, because blower fan in running, produces a large amount of high-temperature gases, although blocked sound, but thermal diffusivity is relatively poor, cause the sound insulation case temperature higher, affect the working life of Roots blower, this is the existing deficiency of prior art.
Summary of the invention
The purpose of this utility model, be exactly for the existing deficiency of prior art, and providing a kind of noise of can blocking not affect the blower technological scheme in working life, the sound-insulating cover of this scheme can be realized the forced convection of air, makes acoustic hood inside temperature and external temperature basically identical.And simple in structure, save material, cost is low.
This programme is achieved by the following technical measures: a kind of sound-insulating cover for Roots blower, comprise Roots blower, cover on Roots blower sound-insulating cover all around, the characteristics of this programme are: at described sound-insulating cover suction port ventilation fan and air outlet ventilating fan are set.When opening Roots blower, ventilating fan is opened synchronously, so that the cross-ventilation in the sound-insulating cover has reduced the temperature in the sound-insulating cover.
The further improvement of this programme has, and described suction port ventilating fan is arranged on the top of sound-insulating cover.From security consideration, be arranged on the top safer.
The further improvement of this programme also has, and described suction port ventilating fan adopts axial-flow blower.
The further improvement of this programme also has, described relief opening ventilating fan be arranged on the equidirectional wall of blower relief opening on.Around blower, form convection currents, prolong the working life of Roots blower.
The beneficial effect of this programme can be learnt according to the narration to such scheme, a kind of sound-insulating cover for Roots blower, comprise Roots blower, cover on Roots blower sound-insulating cover all around, it is characterized in that: at described sound-insulating cover suction port ventilation fan and air outlet ventilating fan are set.The beneficial effects of the utility model are: when opening Roots blower, ventilating fan is opened synchronously, so that the cross-ventilation in the sound-insulating cover has reduced the temperature in the sound-insulating cover, the working life of having improved Roots blower.And simple in structure, practical.
The utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement also is apparent.
