After filling further mixing, the unit for entering back into second group of aerator continues cutting aeration, passes through supplement twice or more than twice
Water aeration, will significantly improve aeration effect and coefficient of oxygen utilization.
Embodiment three
Referring to Fig. 6, the also mountable lower end in the air inlet pipe 12 and upper end of air inlet pipe 12 seals, fan of intake pipe connection 6
Blade face dentation salient point rotary cutting aerator and the mode of the compressed air hose of outside connection are changed to lower part connection, i.e., by air inlet pipe 12
Upper orifice is shut, the lower nozzle of air inlet pipe 12 be it is open, intake pipe connection 6 is mounted on 12 lower part of air inlet pipe, so that it may
To realize the air inlet of aerator lower part, it is suitable for original pond using the transformation of the aerating system of dish-style micro-hole aerator, that is, utilizes
Originally compressed air pipe network is arranged installation.
Example IV
Referring to Fig. 7, the lower end of air inlet pipe 12 can also be connected with air inlet spray head 14 by air inlet spray head connector 13, by air inlet
The nozzle of air supply 10 of 12 bottom of pipe is changed to air inlet spray head 14, and air inlet spray head 14 is connected on air inlet spray head connector 13, to increase gas
Water mixing dynamics, make into aerator air-water mixture more evenly, to enhance aeration effect, air inlet spray head 14 can be adopted
With spiral nozzle or other types of spray head.
Working principle: the compressed air hose of compressed air from the outside enters intake pipe connection 6, then from 12 bottom of air inlet pipe
Nozzle of air supply 10 and water jet be mixed into aerator bottom, due to the buoyancy of air, rapid increase and in aerator
Interior generation relatively low pressure area, also from bottom, indentation aerator forms air-water mixture, mixing wastewater with air to the water of the relatively high pressure in outside
Object passes through the helical duct formed in aerator by flabellum 3, impact at a relatively high speed under climbing power and centrifugal force double action
The dentation salient point 4 being covered in helical duct, air pocket are ground into a large amount of micro-bubble, while generating and swashing in helical duct
Strong stirring, mixing, the effect of mass transmitting of oxygen and water in air strongly, when the mixing wastewater with air for including a large amount of micro-bubbles
When object is gone out at the top of aerator at high speed with spiral shape, strong impact is generated with the water of outside, is mixed, then generates helical form
Air-water mixture rises, and the path of air-water mixture residence time in water and ascending motion is increased, in addition, mixing wastewater with air
Object generates convection action during spiral, and the micro-bubble in air-water mixture compares air pocket because of opposite specific gravity
Greatly, thus the lower part that there is a large amount of micro-bubble to reenter water body under the convection action of water, make in water up and down full of small
Bubble, so that the oxygen in air is adequately dissolved, coefficient of oxygen utilization is obviously increased.
In summary: the utility model flabellum face dentation salient point rotary cutting aerator does not block, and mixing power is strong, non sludge heap
Product, crushing is small, and low energy consumption, energy conservation, and non-maintaining, long-life, performance is stablized, and oxygen delivery capacity will not decline with the increase for using the time
Subtract, be always maintained at DO value stable in pond, is fixedly mounted without bottom of pond, maintenance is very convenient, can without clearing up pond or halt production
Online installation has the micro-bubble ratio generated more thinner, and the path of thread mixing is longer, bubble stop in water when
Between more long, stir it is more violent, it is more fully mixed, therefore transmit that oxygen is more, and dissolved oxygen is promoted and coefficient of oxygen utilization is higher, power consumption
The features such as smaller.
