Abstract
The invention discloses a cabin heat exchange centrifugal fan for wind power generation. The cabin heat exchange centrifugal fan is safe, reliable and high in work efficiency and comprises a base, a motor arranged at the lower end of the base, and a fan volute arranged at the upper end of the base. A motor shaft of the motor extends into the fan volute and is connected with an impeller base. The portion, in the fan volute, of the impeller base is fixedly provided with an impeller through a screw and an impeller pressing plate. An air inlet is formed in the upper end of the fan volute. One side of the fan volute is provided with a square air outlet and a fan protecting net matched with the air outlet. The centrifugal fan has the advantages that as the fan protecting net is additionally arranged on the air outlet, the safety performance of the fan is improved, the air inlet and the air outlet are modified to be square, and the area for instant air inlet and outlet is increased; as the air inlet and the air outlet are connected with the fan volute in an inward-sunken arc mode, the air jetting effect can be improved, the air inlet and outlet efficiency is improved, and the work efficiency is high.
Description
Technical field
The present invention relates to a kind of blower fan, relate in particular to a kind of cabin used for wind power generation heat exchange centrifugal blower.
Background technique
China's wind-power electricity generation is started late, and the Technology origin of most of producers is in abroad.And geographical environment and weather conditions difference external and that I enclose are very big, if copied mechanically and applied indiscriminately, certainly will cause " not acclimatized " of wind power generating set.THE WIND ENERGY RESOURCES IN CHINA enrichment area is often in the area that the temperature difference is large, sand and dust are larger, and wind power generating set not only will be considered ventilation and heat, the cabin heat exchange in the time of also will considering winter low temperature and summer high temperature.In blower fan generating, cabin heat exchange need to use centrifugal blower, the most exhaust outlets of existing cabin heat exchange centrifugal blower do not have protective equipment, and safety coefficient is low, and intake grill and exhaust outlet are all cylinder-like structure simultaneously, air intake and air-out efficiency are low, affect the cabin heat exchange in wind-power electricity generation.
Summary of the invention
Technical problem to be solved by this invention is: a kind of safe and reliable, cabin used for wind power generation heat exchange centrifugal blower that working efficiency is high is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: cabin used for wind power generation heat exchange centrifugal blower, comprise: base, be arranged on the motor of base lower end and be arranged on the volute of blower of base upper end, the motor-shaft extending of described motor enters volute of blower and is connected with impeller base, on impeller base in described volute of blower, by screw and impeller pressing plate, be fixedly installed impeller, upper end at described volute of blower is provided with intake grill, the blower fan protective net that is provided with square exhaust outlet and cooperatively interacts with exhaust outlet in a side of described volute of blower.
In order to solve the problems of the technologies described above better, the further technological scheme that the present invention adopts is: between described intake grill, exhaust outlet and volute of blower, be provided with indent arc guide plate.
Advantage of the present invention is: above-mentioned cabin used for wind power generation heat exchange centrifugal blower, by set up the Safety performance that blower fan protective net has increased blower fan at exhaust outlet, by intake grill and exhaust outlet are repacked into square, increased the area of moment during air inlet/outlet, simultaneously between intake grill and exhaust outlet and volute of blower, adopt indent arc to be connected the jeting effect that can increase air, improved air intake and air-out efficiency, working efficiency is high.

Embodiment
Below in conjunction with the drawings and specific embodiments, describe in detail particular content of the present invention.
As shown in Figure 1 and Figure 2, cabin used for wind power generation heat exchange centrifugal blower, comprise: base 1, be arranged on the motor 2 of base 1 lower end and be arranged on the volute of blower 3 of base 1 upper end, the motor shaft 4 of described motor 2 stretches into volute of blower 3 and is connected with impeller base 5, on impeller base 5 in described volute of blower 3, by screw 6 and impeller pressing plate 7, be fixedly installed impeller 8, in the upper end of described volute of blower 3, be provided with intake grill 9, the blower fan protective net 11 that is provided with square exhaust outlet 10 and cooperatively interacts with exhaust outlet 10 in a side of described volute of blower 3.
As shown in Figure 1 and Figure 2, in this example, for air produces jeting effect when passing in and out volute of blower 3, increase work efficiency, between described intake grill 9, exhaust outlet 10 and volute of blower 3, be provided with indent arc guide plate 12.
When above-mentioned cabin used for wind power generation heat exchange centrifugal blower uses, starting electrical machinery 2, motor shaft 4 impeller seat 5 rotations of motor 2, thereby impeller 8 rotations, blower fan work, during intake grill 9 air intake, because intake grill 9 is square structure, moment incoming air area become large, air enters volute of blower 3 when interior from intake grill 9, through the indent arc guide plate 12 between intake grill 9 and volute of blower 3, air first compresses rear injection, has improved the flow velocity of air, and working efficiency is high, exhaust outlet 10 is consistent with the structure of intake grill 9, and function is consistent.
Above-mentioned cabin used for wind power generation heat exchange centrifugal blower, by set up the Safety performance that blower fan protective net has increased blower fan at exhaust outlet, by intake grill and exhaust outlet are repacked into square, increased the area of moment during air inlet/outlet, simultaneously between intake grill and exhaust outlet and volute of blower, adopt indent arc to be connected the jeting effect that can increase air, improved air intake and air-out efficiency, working efficiency is high.
