Abstract
The utility model discloses a low-noise blower. The low-noise blower comprises an impeller. The low-noise blower is characterized in that an inner layer machine enclosure and an outer layer machine enclosure are arranged outside the impeller, and sound-absorbing cotton is arranged between the inner layer machine enclosure and the outer layer machine enclosure. The low-noise blower is mainly used in places requiring low noise.
Description
Technical field
The utility model relates to a kind of blower fan, relates in particular to a kind of silent ventilator.
Background technique
Blower fan belongs to conventional machinery, and the product that any factory produces is formed by casing, impeller, transmitting assemblies and motor, because product does not have too high technical requirements; Its noise is very big; Do not meet environmental requirement, in order to address this problem, the utility model is transformed the structure of blower fan.
Summary of the invention
The purpose of the utility model is to provide a kind of silent ventilator, with compliance with environmental protection requirements.
For realizing above-mentioned purpose, the technical solution of the utility model is: a kind of silent ventilator, comprise impeller, and it is characterized in that the outside of described impeller 2, be provided with internal layer casing 1 and outer casing 3, be provided with acoustical cotton 4 between internal layer casing 1 and the outer casing 3.
The beneficial effect of the utility model is: owing to be provided with double-deck casing in the impeller outside; And between two-layer casing; Be filled with acoustical cotton; Thereby, most ofly absorbed, thereby reached the purpose of reduction noise compliance with environmental protection requirements by casing itself and acoustical cotton by impeller high speed rotating and pneumatic noise of producing in casing.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Among the figure: 1-internal layer casing, 2-impeller, the outer casing of 3-, 4-acoustical cotton, 5-support.
Embodiment
Below in conjunction with accompanying drawing the utility model and embodiment thereof are done further explain.
Referring to accompanying drawing, the utility model comprises impeller, it is characterized in that: the outside of described impeller 2, be provided with internal layer casing 1 and outer casing 3, and be provided with acoustical cotton 4 between internal layer casing 1 and the outer casing 3.
The outer casing 3 of blower fan is welded by general steel plate; Internal layer casing 1 adopts acoustic board; Between outer casing 3 and internal layer casing 1, be filled with acoustical cotton 4, thereby make impeller 2 high speed rotating and the pneumatic noise major part that produces is absorbed by internal layer casing and acoustical cotton, reached the purpose that reduces noise.Acoustical cotton has commercially available.
