Abstract
A kind of Novel induced draft fan impeller, relate to field of electrical equipment, fan including leaf, protective cover, leaf fan fifth wheel, notch and air-introduced machine connector, described leaf fan fifth wheel be formed around multiple notch being arranged in order, leaf fan it is provided with in described notch, described leaf fan fifth wheel one end is provided with protective cover, leaf fan connector it is provided with inside described leaf fan fifth wheel, this utility model solve impeller in use between there will be dust grease long afterwards and pile up increasingly thicker, affect rotating speed, and not easy cleaning and maintenance, impeller is aging seriously, the peace shifting method on the leaf fan inclined-plane that common impeller has been faced directly the most, air inducing power is weak, this utility model is rational in infrastructure, easy cleaning, maintain, air inducing power is strong, and do not interfere with a kind of Novel induced draft fan impeller of the rotating speed of leaf fan, substantially prolongs the life-span of impeller.
Description
Technical field:
This utility model relates to field of electrical equipment, is specifically related to a kind of Novel induced draft fan impeller.
Background technology:
Air-introduced machine is widely used in the ventilation of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building, dust discharge and cooling；Boiler and the ventilation of industrial furnace and air inducing；Cooling in the apparatus of air conditioning and domestic electric appliance and ventilation；The drying of corn and selecting and recommending；Wind-tunnel wind regime and the inflation of aircushion vehicle and propelling etc..The operation principle of air-introduced machine is essentially identical with turbocompressor, only because gas flow rate is relatively low, pressure change is little, typically without the concern for the change of gas specific volume, i.e. gas is processed as incompressible fluid.
Existing draught fan impeller is generally with welding leaf fan in the middle of upper and lower circle wheel, based on a side opening in the middle of impeller, this leaf fan rotating speed when rotating is high, air inducing power is strong, can this impeller in use between there will be long afterwards dust grease pile up increasingly thicker, affect rotating speed, and not easy cleaning and maintenance, impeller is aging seriously, the peace shifting method on the leaf fan inclined-plane that common impeller has been faced directly the most, air inducing power is weak, hinders production and processing.
Utility model content:
Technical problem to be solved in the utility model be to overcome existing technological deficiency provide a kind of rational in infrastructure, easy cleaning, maintain, air inducing power is strong and does not interferes with a kind of Novel induced draft fan impeller of rotating speed of leaf fan.
Technical problem to be solved in the utility model uses following technical scheme to realize:
A kind of Novel induced draft fan impeller, it is characterized in that: include leaf fan, protective cover, leaf fan fifth wheel, notch and air-introduced machine connector, described leaf fan fifth wheel be formed around multiple notch being arranged in order, leaf fan it is provided with in described notch, described leaf fan fifth wheel one end is provided with protective cover, is provided with leaf fan connector inside described leaf fan fifth wheel.
Further, the described " u "-shaped that leaf fan is certain radian, can be when running, the wind extracted large-area can be brought into air outlet, will not put incessant sweating due to affection by pathogenic wind power.
Further, the lower section of described leaf fan mouth of connecting trough is provided with fastener, convenient cleaning and maintenance so that leaf fan is difficult to aging.
Further, described protective cover is semicircle cover body, when air inducing, can will not be incorporated into inside with dust such as, and circular cover body can allow wind-force preferably take out of through leaf fan.
The beneficial effects of the utility model are: 1, and when running, the wind extracted large-area can be brought into air outlet, will not put incessant sweating due to affection by pathogenic wind power.2, convenient cleaning and maintenance so that leaf fan is difficult to aging.3, can will not be incorporated into inside with dust such as, circular cover body can allow wind-force preferably take out of through leaf fan.
Accompanying drawing illustrates:
Fig. 1 is Facad structure schematic diagram of the present utility model.
Fig. 2 is cross-sectional view of the present utility model.
Fig. 3 is structure schematic diagram of the present utility model.
Detailed description of the invention:
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with being specifically illustrating, this utility model is expanded on further.
As Figure 1-3, a kind of Novel induced draft fan impeller, it is characterized in that: include leaf fan 1, protective cover 2, leaf fan fifth wheel 3, notch 4 and air-introduced machine connector 6, described leaf fan fifth wheel 3 be formed around multiple notch 4 being arranged in order, described leaf fan 1 is arranged in notch 4, described protective cover 2 is arranged on leaf fan fifth wheel 3 one end, and described leaf fan fifth wheel 3 is internal is provided with leaf fan connector 6.
Described leaf fan 1 is the " u "-shaped of certain radian, can be when running, and the wind extracted large-area can be brought into air outlet, will not put incessant sweating due to affection by pathogenic wind power.
Described leaf is fanned the lower section of 1 mouth of connecting trough and is provided with fastener 5, convenient cleaning and maintenance so that leaf fan 1 is difficult to aging.
Described protective cover 2 is semicircle cover body, when air inducing, can will not be incorporated into inside with dust such as, and circular cover body can allow wind-force preferably take out of through leaf fan 1.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
Claims (4)
