Description
The technical field is as follows:
the utility model belongs to the technical field of sound-proof equipment, in particular to room that gives sound insulation of making an uproar falls in fan.
Background art:
industrial fans in domestic and foreign markets generally adopt two-stage to eight-stage rotating speeds, and the lower the rotating speed is, the larger the noise which may appear is. Most of the silencers matched with the fans can achieve the best effect that the noise outside the silencer is 85 db. However, when the fan room is near a living area or a factory needs low noise, the silencer of the existing fan cannot meet the requirements.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.
The utility model has the following contents:
an object of the utility model is to provide a room that gives sound insulation of making an uproar falls in fan to overcome the defect among the above-mentioned prior art.
In order to achieve the purpose, the utility model provides a noise reduction and sound insulation room for a fan, which is formed by splicing sound insulation unit plates; the sound insulation unit plate is of a rectangular structure and comprises an outer panel, a sound insulation layer, an inner panel and a keel, the keel is arranged between the outer panel and the inner panel, the keel is connected with the outer panel and the inner panel through welding, the outer panel, the inner panel and the keel form a hollow structure, and the sound insulation layer is filled in the hollow structure; the sound insulation layer comprises a rock wool layer, a glass wool layer and an alkali-free glass fiber cloth layer, wherein the rock wool layer is positioned at the outer side and is in contact with the outer panel, the glass wool layer is positioned at the middle part and is respectively connected with the rock wool layer and the alkali-free glass fiber cloth layer, the alkali-free glass fiber cloth layer is positioned at the inner side and is in contact with the inner panel; the sound insulation unit plates are connected into a whole through welding among the keels; the outer panel and the inner panel are made of galvanized plates.
Preferably, in the technical scheme, the thickness of the glass wool layer is 50mm, and the thickness of the rock wool layer is 70 mm.
Compared with the prior art, the utility model discloses following beneficial effect has:
through setting up the room that gives sound insulation in the fan outside, the noise can fall the fan noise below 60db through the processing of the interior noise elimination material of sound insulation layer for the area that can not set up the fan because the noise factor also can use the fan, has enlarged the application of fan.

The specific implementation mode is as follows:
the following detailed description of the embodiments of the present invention is provided, but it should be understood that the scope of the present invention is not limited by the embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
Example 1
As shown in fig. 1-4, a noise reduction and sound insulation room for a fan is formed by assembling sound insulation unit plates; the sound insulation unit plate is of a rectangular structure and comprises an outer panel 1, a sound insulation layer 2, an inner panel 3 and a keel 4, the keel 4 is arranged between the outer panel 1 and the inner panel 2, the keel 4 is of a rectangular structure and comprises a transverse keel and a vertical keel, the transverse keel forms a long edge and a central line of the rectangular structure, the vertical keel forms a short edge of the rectangular structure, the vertical keel is uniformly distributed on the transverse keel of the central line, the keel 4 is connected with the outer panel 1 and the inner panel 2 in a welding manner, the outer panel 1, the inner panel 2 and the keel 4 form a hollow structure in a surrounding manner, and the sound insulation layer 2 is filled in the hollow structure; the sound insulation layer 2 comprises a rock wool layer 5, a glass wool layer 6 and an alkali-free glass fiber cloth layer 7, wherein the rock wool layer 6 is positioned on the outer side, the rock wool layer 6 is in contact with the outer panel 1, the glass wool layer 6 is positioned in the middle, the glass wool layer 6 is respectively connected with the rock wool layer 5 and the alkali-free glass fiber cloth layer 7, the alkali-free glass fiber cloth layer 7 is positioned on the inner side, and the alkali-free glass fiber cloth layer 7 is in contact with the inner panel 2; the sound insulation unit plates are connected into a whole through welding between keels 4; the outer panel 1 and the inner panel 2 are made of galvanized plates, wherein the thickness of the outer panel 1 is 1.5mm, the thickness of the inner panel 2 is 1.0mm, the thickness of the glass cotton layer 6 is 50mm, and the thickness of the rock wool layer 5 is 70 mm.
The fan during operation, the noise that produces gets into the puigging, because rock wool, glass cotton, the fine cloth of alkali-free glass in the puigging all have a large amount of little holes, the noise sound wave gets into along the hole, makes air and hole inner wall friction through the vibration, turns into acoustic energy into heat energy and consumes. Set up the room that gives sound insulation in the fan outside, the noise can fall the fan noise below 60db through the processing of the interior noise elimination material of sound insulation layer for the area that can not set up the fan because the noise factor also can use the fan, has enlarged the application of fan.
The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. It is not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and its practical application to enable one skilled in the art to make and use various exemplary embodiments of the invention and various alternatives and modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims and their equivalents.
