Abstract
The invention discloses an energy-saving two-stage fan comprising a ventilation channel and a motor-driven device. The energy-saving two-stage fan is characterized in that the ventilation channel is formed by an outer air cavity and an inner air cavity; the motor-driven device is formed by a motor, a shaft coupling device, an inner shaft, an outer shaft, gears and a shaft connected with the inner air cavity; the inner shaft is sleeved with the outer shaft, and opposite rotation of the inner shaft and the outer shaft is achieved so that a second-stage impeller connected with the outer shaft and a first-stage impeller connected with the inner shaft can be driven to rotate. The front and back contra-rotating impellers of the contra-rotating fan are reserved, the number of motors is reduced to one, and cost and use expenses are saved.
Description
Technical field
The present invention relates to field of ventilation equipment, especially a kind of energy-conservation two-stage ventilator.
Background technique
The ventilation equipment that current large-scale place uses have main fan and booster, mainly contain axial flow, centrifugal and convection rotary type three kinds of structures.Main fan is arranged in the separate cavities of I and II air duct by the common motor that impeller is housed.Booster the blower fan definite-purpose motor of impeller or flange-type motor will be housed in I and II air duct, and what have fixes by dunnage, and what have then fixes with cylinder.That the blower fan of main fan or booster convection rotary type mechanism all has obvious advantage, but contra-rotating fan to realize revolving by installing driven by motor two impeller respectively in the separate cavities of firsts and seconds air duct respectively, this makes counter rotating fan complex structure, body is heavy, price is high, consume energy high, often second-stage electric machine is overloaded because sencond stage impeller working environment increases than one stage impeller official post sencond stage impeller air horsepower and burns, especially growing apart from high blast ventilation situation, this accident more easily occurs.
Summary of the invention
Object of the present invention carries out technological innovation to original counter-rotating axial flow fan structure exactly, is keeping, on the basis that its efficiency is high, air supplying distance is long, optimizing product structure, reducing volume, improve its technical performance index further.Product advantage after improvement is, retains front and back two contra-rotating impeller of contra-rotating fan and motor number is reduced to one, cost-saving and cost of use.
In structure optimization, the energy-conservation two-stage ventilator of one of the present invention, comprise vent passages and maneuvering gear, it is characterized in that: vent passages is formed by exogenous wind chamber (11), interior wind chamber (10), maneuvering gear is by motor (1), hitch bar (2), interior axle (9), outer shaft (4), gear (2,3,7) axle (8) and with interior wind chamber be connected forms, outer shaft (4) is enclosed within interior axle (9), and interior outer shaft is realized revolving thus driving the sencond stage impeller be connected with outer shaft and the one stage impeller be connected with interior axle to rotate.
Accompanying drawing explanation
Fig. 1 is a kind of energy-conservation two-stage ventilator schematic diagram;
Fig. 2 is two-stage bispin structural drawing.
specific implementation process
The energy-conservation two-stage ventilator of one of the present invention, comprise vent passages and maneuvering gear, vent passages is formed by exogenous wind chamber 11, interior wind chamber 10, maneuvering gear is made up of motor 1, hitch bar 2, interior axle 9, outer shaft 4, gear 2,3,7 and the axle 8 that is connected with interior wind chamber, outer shaft 4 is enclosed within interior axle 9, and interior outer shaft is realized revolving thus driving the sencond stage impeller be connected with outer shaft and the one stage impeller be connected with interior axle to rotate.
Claims (1)
1. an energy-conservation two-stage ventilator, comprise vent passages and maneuvering gear, it is characterized in that: vent passages is formed by exogenous wind chamber (11), interior wind chamber (10), maneuvering gear is by motor (1), hitch bar (2), interior axle (9), outer shaft (4), gear (2,3,7) axle (8) and with interior wind chamber be connected forms, outer shaft (4) is enclosed within interior axle (9), and interior outer shaft is realized revolving thus driving the sencond stage impeller be connected with outer shaft and the one stage impeller be connected with interior axle to rotate.
