Abstract
The utility model discloses a centrifugal induced draft fan which comprises a casing. The centrifugal induced draft fan is characterized in that the casing is cylindrical; an exhaust opening is formed in one end of the casing; a centrifugal impeller connected with a motor shaft is arranged at the other end of the casing; and rectangular ring sealing structures which are mutually meshed are arranged on an impeller body at the periphery of the exhaust opening of the centrifugal impeller and a casing corresponding to the impeller body. According to the centrifugal induced draft fan disclosed by the utility model, the casing and the impeller structure are adopted and the corresponding sealing structures are added. The centrifugal induced draft fan has the characteristics of high air inducing efficiency, high air volume and simple structure.
Description
Technical field:
The utility model belongs to the blower fan technical field, is specifically related to a kind of centrifugal induced draught fan.
Background technique:
Induced draught fan is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and it is a kind of driven fluid machinery.Induced draught fan is widely used in ventilation, the dust discharge and cooling of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building; The ventilation of boiler and industrial furnace and air inducing; Cooling and ventilation in the apparatus of air conditioning and domestic electric appliance; The oven dry of cereal and selecting and recommending; The inflation of wind-tunnel wind regime and Hovercraft and propelling etc.Working principle and the turbocompressor of induced draught fan are basic identical, and just because gas flow rate is lower, pressure changes little, does not generally need to consider the variation of gas specific volume, namely gas is processed as incompressible fluid.
Traditional induced draught fan is due to its reasons in structure, inefficiency, and air quantity is little, haves much room for improvement.
The model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of centrifugal induced draught fan is provided, and the gap backflow of this blower fan is revealed small, and air inducing efficient is high.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of centrifugal induced draught fan, comprise housing, it is characterized in that: described housing is cylindrical body, one end of this housing is the air sucking mouth, the receded disk impeller that is connected with motor shaft is arranged on the other end of housing, is provided with intermeshing rectangular ring sealing configuration on the air sucking mouth of the receded disk impeller periphery impeller body housing corresponding with it.
Beneficial effect: the utility model adopts described housing and blade wheel structure, has increased corresponding sealing configuration, has the advantages that air inducing efficient is high, air quantity is large, simple in structure.
Description of drawings:
Fig. 1 is the sectional view of the utility model structural representation;
Fig. 2 is the sectional view of sealing configuration described in the utility model.
Embodiment:
Embodiment: see illustrated in figures 1 and 2, a kind of centrifugal induced draught fan, comprise housing 3, described housing 3 is cylindrical body, one end of this housing 3 is air sucking mouths 4, the receded disk impeller 1 that is connected with motor shaft 2 is arranged on the other end of housing 3, is provided with intermeshing rectangular ring sealing configuration 6 on the peripheral impeller body in the air sucking mouth 5 of receded disk impeller 1 housing corresponding with it.
