Description
Technical field
The invention belongs to technical field of aquaculture, and in particular to a kind of paddle aerator.
Background technology
Aerator, it is a kind of more commonly used machine of fishery cultivating industry, is driven by power sources such as motor or diesel engines
Dynamic workpiece, makes " oxygen " in air to be quickly transferred to the equipment in breeding water body, and the machine is mainly used for increasing in water
Oxygen content, with ensure the biologies such as the fish in water will not anoxic, while can also suppress the growth of anaerobic bacteria in water, prevent pond
Aqueous metamorphism threatens island Fish Survival environment.The machine is usually that the air pump carried using it is squeezed into air in water, is come with this
Realize the purpose of increase water oxygen content.Can not only solve that caused fish floats because of anoxic in pond culture using aerator
The problem of head, and pernicious gas can be eliminated, promote water body convective exchange, improve condition of water quality, reduce feed coefficient, improve
Fishpond activity and primary productivity, so as to improve breeding density, the intensity of feeding of increase cultivation object, promote growth, make mu
Production increases substantially, and sufficiently achieves the purpose that cultivation increases income.
In jet aerator, all using three-phase alternating current, rated speed that motor dispatches from the factory exists defeated in actual applications
Go out the problem of unstable, the actual rotating speed of motor is less than rated speed；Overloading problems also be present, such as the specified work(of motor
Rate is 1500W, and the power in actually using is 1900-2000W, has seriously exceeded rated output, and use cost is high, uses the longevity
Life is low.In addition, using three-phase alternating current, once phase shortage, motor just can not normal work, long-time phase shortage easily burns out electricity
Motivation coil windings, causing motor to burn out can not start.In addition, conventional three-phase motor uses iron casting motor housing, because
Heat can be produced under electric machine operation state, is limited by use environment and easily generation salt efflorescence is often contacted with water body, motor housing holds
Perishable damage of getting rusty.
And the motor used in jet aerator its rotor structure, as shown in figure 9, being mostly directly in hollow cylinder
8 dovetail groove projections 12 are set on the periphery of the iron core 11 of body, and dovetail groove protruding block is integrally formed with iron core, 8 dovetail geosynclinal convexs
The dovetail groove of bittiness arbitrary neighborhood between the two is correspondingly provided with 8 magnetic links 13, the insertion dovetail groove fitting of annular magnetic links 13
The outer surface of cylinder, the outer surface of cylinder and the inner surface of magnetic links are directly realized by spreading glue layer 14 and bonded.This
The rotor of kind structure, in production process is manufactured, there are the following problems：Each dovetail groove between two dovetail groove projections is applied
When covering glue, because the dovetail groove of dovetail groove projection be present, glue is directly smeared from outer surface in the presence of inconvenient, also glue painting
Smear and also easily smear uneven, push magnetic links 13 from one side of the outer surface 111 of fitting cylinder during installation, gradual magnet steel
The inner surface 131 of piece 13 shifts the outer surface 111 of fitting cylinder completely onto, and the appearance of cylinder will be applied to during the push
The paste portion in face pushes out so that magnet steel plate inner surface, cylinder outer surface 111 glue missing, glue it is uneven,
Cause to need to repeat gluing in process, have impact on the firmness between magnetic links, cylinder so that the use of whole rotor
Service life reduction.In addition, magnetic links are easily lost in this rotor in use, the magnetic links on rotor cylinder easily take off
Glue, come off even fragmentation.
In jet aerator, impeller mostly uses plastic material, and plastic impeller surface sets a circle to fetch water and blade and fetched water
Blade height is equal to plastic impeller height, and impeller is arranged on aerator and is centrally located at below motor, and this structure impeller turns
Dynamic space is limited, and the amount of fetching water that blade of fetching water rotates is little, can increased oxygen amount by motor power (output), impeller size influenceed compared with
Greatly, impeller and air contact area are limited, limited to the increased amount of oxygen of water body within the unit interval, and are made an uproar in operation process
Sound is larger；The impeller of plastic material easily accumulates algae moss in use, is placed in water easy to aging, plastic blade need for a long time
Certain thickness is wanted, therefore is increasing the resistance of rotation, oxygenation effect is influenceed, increases the bearing power of motor so that whole three
Phase motor bears a heavy burden high and the problem of easily burning out be present；Other paddle aerator is typically by impeller, motor, control device, several
Individual floating body etc. is formed, and impeller is set in the bottom of motor, and impeller is extend into below the water surface, is realized by control device to motor
Control, wheel rotation is moved by motor rotational band, wheel rotation drives spray of water, realizes that oxygen enters water body in an air
Purpose；And in this structure aerator, control device is set together with motor, impeller, in the process of wheel rotation oxygenation
In, spray of water, easily get control device wet, once control device failure, can cause electric leakage, aerator to be stopped etc. and ask
Topic, is likely to result in security incident when serious.
