Abstract
The utility model relates to an impeller-type oxygenator for aquaculture industry. Primarily, a wheel hub is provided with a central hole which is connected with a horizontal water blocking plate, a wheel upper section and a wheel hub lower section arranged above the water blocking plate and under the water blocking plate are respectively provided with a plurality of upper through holes and lower through holes, and the outer margin lower section of the wheel hub is provided with a plurality of inclined impeller blades. Thereby, the oxygenating amount in water is added, and the oxygen supply is reliable.
Description
The utility model relates to the oxygen increasing equipment that uses in a kind of aquaculture industry.
At present, common paddle aerator is directly or through decelerator impeller sheet to rotate in water with motor, mixes with water and produce the negative pressure oxygen intake, and still, it is still little to draw amount of oxygen in the water.
In view of this, the purpose of this utility model provides a kind of paddle aerator, offers passage on rotary hub, makes oxygen have stationary conduit to enter in the water, enters oxygen-supplying amount in the water with increase.
The purpose of this utility model is achieved in that a kind of paddle aerator comprises a floating seat, a motor and a rotating shaft, it is characterized in that: set firmly a wheel hub in the rotating shaft lower end, has centre bore in this wheel hub, and outer rim connects a horizontal water fender, offer through hole on several, lower through-hole respectively at the wheel hub epimere and the hypomere of this water fender upper and lower again, the outer rim lower section at wheel hub is provided with narrow meshed several pieces inclination impeller blades again.
Described impeller blade and hub axis tilt 25 °-35 °.
Described impeller blade is three and is distributed on the wheel hub outer rim.
Owing to adopt such scheme: increase oxygenation amount in the water, and oxygen supply is reliable.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 the utility model exemplary embodiments schematic diagram.
Fig. 2 the utility model exemplary embodiments wheel hub and impeller blade schematic diagram.
Among the figure: through hole, 43 lower through-holes, 44 water fenders, 5 impeller blades, 51 apertures on 1 floating seat, 11 supporting bases, 12 floating drums, 2 motors, 21 motor cover, 3 rotating shafts, 4 wheel hubs, 41 centre bores, 42.
Present embodiment mainly comprises floating seat 1, motor 2, rotating shaft 3, wheel hub 4 and several pieces impeller blades 5, as shown in Figure 1, 2, and wherein:
Floating seat 1 is that the supporting base 11 supported by three uniform overhanging floating drums 12 (in establish bearing) constitutes, on supporting base 11, support to prevent in addition the motor 2 of motor cover 21, connect a rotating shaft 3 with shaft coupling and be bearing in the supporting base 11 at the axle head of this motor 2, rotate synchronously with motor 2, all belong to prior art.
Three impeller blades 5 are to become 25 °-35 ° uniform obliquely wheel hub 4 hypomeres (place, lower through-hole 43 places) that are connected with wheel hub 4 axis, offer several apertures 51 on this impeller blade 5, reduce the resistance of impeller blade 5 in water, air is fully mixed with water.
The operation principle of present embodiment is as follows:
When the motor 2 of floating seat 1 to support at the buoyancy of the water surface, drive wheel hub 4, in water, rotate the generation vortex through rotating shaft 3 until three impeller blades 5, air on vortex produces negative pressure, the air of water fender 44 belows is sucked in the water, simultaneously, last through hole 42 sucks air and enters centre bore 41, enters the water from lower through-hole 43 again, and fully mix with water, reach abundant oxygenation effect.
Claims (3)
1, a kind of paddle aerator comprises a floating seat (1), a motor (2) and a rotating shaft (3), it is characterized in that: set firmly a wheel hub (4) in rotating shaft (3) lower end, has centre bore (41) in this wheel hub (4), and outer rim connects a horizontal water fender (44), offer through hole on several (42), lower through-hole (43) respectively at wheel hub (4) epimere and the hypomere of this water fender (44) upper and lower again, be provided with several pieces inclination impeller blades (5) of band aperture (51) again at the outer rim lower section of wheel hub (4).
2, by the described a kind of paddle aerator of claim 1, it is characterized in that: described impeller blade (5) tilts 25 °-35 ° with wheel hub (4) axis.
