Submerged aerator with gas cylinder direct air-intake

An air guide, submersible-floating technology, applied in water aeration, sustainable biological treatment, water/sludge/sewage treatment, etc., can solve the problem of fragile, poor water-air mixing effect, and inability to form atomization. Bubbles and other problems can be eliminated, and the effects of enhanced stirring and pushing flow, remarkable energy saving effect and high pressure difference can be achieved

Problems solved by technology

[0009] Then, because there are many connecting points between the ventilation pipe 4, the sealing rotary joint 6, the flange 7 and the upper shaft extension 14 of the motor, they are easily damaged in practical applications.
[0010] Finally, because the jet impeller 11 just throws the air sent into the water by the centrifugal fan 1 into the water body, the mixing effect of water and air is not good, and it is impossible to form atomized tiny bubbles

Abstract

The invention discloses a submersible floating aerator with direct air intake from an air cylinder. The aerator mainly comprises a fan holder (2), an air inlet (3), a submersible hollow-axis motor (9). A gas ring compressor (29) is fixed on the fan holder (2) through a support (34). The fan holder (2) is welded and fixed on an upper end of an air cylinder (35). An air outlet (30) and the air inlet (3) of the gas ring compressor (29) are sealed and connected through a stainless steel pipe or a hose (33). A lower end of the air cylinder (35) is fixed with a first motor flange (19) through a first flange (36). A second motor flange (20) is fixed with an air guide sleeve (38) through a second flange (37). A lower shaft extension (18) of the submersible hollow-axis motor is coaxially connected with a propeller assembly consisting of a propeller (39), a jet mixer (40) and vapor crushing slices (41). With the technical proposal, the aerator can carry out deepwater aeration.

Description

technical field [0001] The invention relates to a submersible aerator which is suitable for aerating and increasing oxygen in a deep water area in a sewage purification biological treatment method to increase dissolved oxygen content and dissolved oxygen saturation in sewage, and is directly fed by an air guide cylinder. Background technique [0002] There are a large number of microorganisms in nature, which have the ability to oxidize and decompose complex organic and certain inorganic substances, and convert these substances into simple substances, or convert toxic substances into non-toxic substances. Practice has shown that the use of microorganisms to treat organic matter in wastewater has the advantages of low investment, high efficiency, stable operation, low operating costs, good effluent quality, good sludge settling performance, and can be used as fertilizers. Among the biological treatment methods, the activated sludge method occupies an extremely important posit...
