Description
Technical field
The invention belongs to fishery cultivating field of mechanical technique, and in particular to a kind of oxygen increasing machine impeller and have the aerator leaf
The aerator of wheel.
Background technology
Paddle aerator is that Shanghai fishing machine was succeeded in developing in 1972, and nearly 30 provinces and the southeast have been promoted in the whole nation at present
Subregion, now possesses tens million of.Pond culture per mu yield is promoted the use of by past 5~600 with paddle aerator
Jin once brings up to that very heavy or even 7~8 is very heavy, is known as rescuing fish machine by numerous fishermen, volume increase machine is pond culture revolution,
It is also that current oxygenation effect is best and indispensable fishery machinery at the same time.
Fisherman is often that more aerators are placed in a pond for the maximization devoted exclusive attention to output, so that pond yields obtain
To improve, the increasing of increase and feeding amount however as yield result in the deterioration of breeding water body and taking place frequently for fish disease, fishman
The pond waters of processing aging are often simply changed water, and treatment fish disease is exactly largely to use disinfectant and antibiotic.Support
Grow waste water and directly discharge the pollution for having aggravated rivers,lakes and seas and the waste of groundwater resources.And in fish disease therapeutic process, fishing
Medicine largely uses the serious threat food security of people and compromises the safety of surface water.According to the 9th phase in 2014《Science is led to
Report》Investigated and found by the research team of East China University of Science, Tongji University and Tsinghua University：It is anti-containing 68 kinds in China's surface water
Raw element, and concentration is far above foreign countries.In this regard, environmental protection administration explicitly indicates that its main pollution source comes from aquaculture, including
Culture fishery.
For case above fishman for the maximization of itself economic interests and benefit, handle the pond waters of deterioration into
Row simply changes water；But the direct discharge of pond waste water has aggravated the pollution of rivers and the waste of groundwater resources.Fish disease is big
In part because using caused by substantial amounts of disinfectant and antibiotic, and the food of a large amount of people using serious threat of fishing medicine are pacified
Entirely.
Researcher, which studies, during the use of aerator finds：Breeding water body oxygenation relies primarily on photosynthesis.Noon
The period that illumination is most sufficient in one day afterwards, and in water phytoplankton the photosynthesis most active period.Due in water body
Most deep can only achieve the transparent depth of water body twice of photosynthesis, when fish pond surface water body dissolved oxygen amount reaches over-saturation, middle and bottom layers
Water body also in oxygen debt state, at this moment just need paddle aerator to be stirred and be aerated, the over-saturation dissolved oxygen on upper strata
Water body takes middle bottom to, and the oxygen debt water body of bottom takes upper strata to and carries out photosynthesis in, while pernicious gas such as ammonia bottom of pond,
Hydrogen sulfide, methane, carbon monoxide etc. take the water surface to by waterfall qi leel solution, are improved fish pond entirety dissolved oxygen level, and
Reduce the harmful substance in water body.The thermocline of cultivating pool water body can effectively be removed by opening aerator.Oxygen spring layer passes through
The aeration performance of aerator, the harmful substance in breeding water body are effectively removed, and improvement pond water quality, which is played, actively to be had
The effect of effect.
Researcher further study show that：The wheel rotation of fine day noon aerator stirs water body, makes bottom water upward
Lifting, then outwards pushed open by top layer center, so as to form a large-scale stereo circulating current, make whole water body and air
Contact, is irradiated by sunlight；Phytoplankton discharges substantial amounts of oxygen through photosynthesis, makes upper strata supersaturation dissolved oxygen water body and bottom
Low dissolved oxygen water body is constantly swapped, mixed, and improves the dissolved oxygen of whole water body.Vane type oxygenation can form larger water
Jump, aeration and air contact have effectively decomposed the harmful substance in breeding water body, form benign cycle；And by sunlight
Ultraviolet light irradiation, the harmful microorganism in water body is suppressed again, kills water body and is purified the reason of " Running water never becomes putrid "
It is achieved, its effect is more notable with the extension of available machine time.If have in pond an oxygenation function 24 it is small when open
It is the problem of can solve the above to open and constantly pond waters are stirred with water and aeration, and the 24 of 3kw aerators open fishing when small
People's panesthesia is power-consuming and adds aquaculture cost.Feel to change that water most directly quick and cost is minimum, daytime aerator unlatching
Ingesting for fish can also be influenced by forming substantial amounts of hydraulic jump.
The design feature of paddle aerator is that higher power and rotating speed form larger hydraulic jump based on oxygenation to stir
Supplemented by water aeration.Discovery is constantly furtherd investigate through researcher：Pond waters is formed upper and lower circulative convection and be not required to
Want larger power and rotating speed；Suitable aeration hydraulic jump can effectively remove the harmful substance in water body.If existing vane type
Start and waste that is uneconomical and causing the energy when aerator 24 is small.Accordingly, successively have developed again with relatively low rotating speed 3 ~ 4
Turn/min, less 40 ~ 60 W of power, drive one group of wheel rotation, there is the water-ploughing machine of stir water function and utilize water-ploughing machine
Principle optimizes impeller shape, increases the surge machine of wheel speed and power of motor.Water-ploughing machine power is too small to be relatively adapted to low yield
Pond, surge machine have the function of to make well unrestrained, realize the convection current up and down of pond waters, but the hydraulic jump formed is smaller goes to remove water
Harmful substance ability in body is poor.Then again have developed on paddle aerator install additional auxiliary-motor cultivated aerator in water and
Attached with frequency converters changes frequency of supply, regulation motor rotating speed and the impeller for reducing power of motor on original paddle aerator
Aerator in water is ploughed in formula frequency conversion.The former gearbox designs are complicated, manufacture fisherman of high cost and are difficult to receive；The latter is due to having installed frequency conversion additional
Though device rotating speed and power are reduced but the high fisherman of frequency converter price is difficult to receive at this stage, and with special variable-frequency motor.
Frequency converter is influenced by use environment, often protects motor to cause not working for aerator in advance, and prestige is shut down in premature protection
The safety of cultivating pool is coerced, so being not particularly suited for cultivating pool.The so external cultivating pool in the foster pond in the country is also in this way, real
