Description

Aerator

Technical field

The utility model relates to the aerator of used for aquiculture.

Background technology

The most frequently used aerator in the aquaculture industry, oxygenation effect aerator preferably has paddle aerator, waterwheel aerator, jet aerator etc., but these aerators are all only joined a kind of impeller, thereby the mode of oxygenation and function just be confined to a kind of pattern, and oxygen transfer rate and oxygenation efficient just can not further improve.

Summary of the invention

Therefore, the purpose of this utility model is to provide a kind of aerator, by having the impeller of two kinds of different types different rotating speeds, realizes the oxygenation of different modes, thereby has improved oxygen transfer rate and oxygenation efficient, has saved the energy.

The purpose of this utility model is achieved in that

A kind of aerator comprises motor, decelerator, two kinds of multi-form impellers, supporting arm and buoyancy aids, and decelerator comprises gear-box and gear train again.

The characteristics of the utility model maximum are that inside and outside two different output shafts of rotating speed are arranged on the same axis of decelerator output, and these two output shafts connect the impeller of two kinds of different types respectively, thereby realize the oxygenation of different modes simultaneously.This decelerator is that the output shaft of realizing two same axis is like this exported different rotating speeds and power.Motor shaft head stretches into first order driving gear is housed in the decelerator.First order driving gear and first driven gear engagement that is contained on the jackshaft rotate thereby drive the jackshaft that is contained in the decelerator.Two driving gears also are housed: go up driving gear and following driving gear on the jackshaft.Last driving gear and the last driven gear engagement that is contained on the interior output shaft, thus output shaft rotates in driving.Following driving gear and the following driven gear engagement that is contained on the outer output shaft rotate thereby drive outer output shaft.Interior output shaft is connected with small impeller, and outer output shaft is connected with big impeller.

Inside and outside output shaft of the present utility model all passes through the two-stage speed change and drives big or small wheel rotation respectively.The small impeller that interior output shaft drives, diameter is little, blade is many, the rotating speed height, and the spray of playing is many, the spread is good, thereby the oxygen transfer rate height, the water lift ability is strong simultaneously, and water body is exchanged up and down, make following water body put on the water surface and air even contact absorption oxygen, thereby realize water body surface layer and all oxygenation of deep layer.And the big impeller diameter that outer output shaft drives is big, and blade is few, and rotating speed is low, thereby its oxygen transfer rate is not as good as small impeller.But it rotates with slower speed because diameter is big, and the water body that drives in a big way rolls, and its blade is arranged on the water body periphery that small impeller rolls.Therefore it except self playing certain oxygenation, bigger effect be through small impeller oxygenation water body push the four directions to, diffusion has rapidly improved the scope of oxygenation water body greatly.The impeller of the oxygenation way that two kinds of different types are different is worked together, effectively improves oxygen transfer rate and oxygen transfer efficiency, has saved the energy.

Embodiment

The utility model is described in further detail below in conjunction with embodiment:

Embodiment, in conjunction with Fig. 1 to Fig. 3, a kind of aerator comprises protective cover 1, motor 2, gear-box 3, gear train, outer output shaft 4, interior output shaft 5, big impeller 6, small impeller 7, supporting arm 8, buoyancy aid 9.Gear train comprises first order driven gear 12, goes up driving gear 13 and following driving gear 14.Supporting arm 8 one ends are installed on the gear-box, and the other end is connected in buoyancy aid 9.Interior output shaft 5 is located in outer output shaft 4 bodies, and interior output shaft 5 axially passes outer output shaft 4, is connected by bearing between interior output shaft 5 and the outer output shaft 4, is rotatably assorted between the two.Between outer output shaft and the gear-box also is to be connected by bearing, is rotatably assorted between the two.

Output shaft and outer output shaft rotated in motor 1 drove after slowing down, thus drive be contained on the output shaft 5 small impeller 7 and be contained in and export big impeller 6 on the uranium 4 outward with different speed rotations, finish the oxygenation of different modes.

Motor shaft head stretches in the gear-box and first order driving gear 10 is housed, first order driving gear 10 and first order driven gear 11 engagements that are contained in jackshaft 12, rotate thereby drive jackshaft 12, first order driving gear 10 diameters are less than first order driven gear 11 diameters.Last driving gear 13 and following driving gear 14 are fixed on the jackshaft 12 simultaneously, last driving gear 13 and last driven gear 15 engagements that are contained in interior output shaft 5 tops, thus output shaft 5 rotates in driving, and interior output shaft 5 bottoms are stretched out gear-box and small impeller 7 are housed.Following driving gear 14 and following driven gear 16 engagements that are contained in outer output shaft 4 tops rotate thereby drive outer output shaft 4, and outer output shaft 4 bottoms are stretched out gear-box and big impeller 6 is installed.The slightly larger in diameter of last driving gear 13 is in last driven gear 15 diameters, and following driving gear 14 diameters then are far smaller than down driven gear 16 diameters, so the small impeller rotating speed is greater than big wheel speed.Small impeller 7 diameters are little, and blade is many, the rotating speed height, and the spray of playing during rotation is many, and the spread is good, thereby the oxygen transfer rate height, and the water lift ability is strong simultaneously, and water body is exchanged up and down, makes following water body put on the water surface and air even contact absorption oxygen.Thereby realize water body surface layer and all oxygenation of deep layer.Because the impeller diameter of small impeller 7 is less, so the scope of oxygenation water body is not too large.And big impeller 6 diameters are big, blade is little, and rotating speed is low, and oxygen transfer rate is not as good as small impeller 7, but it is because diameter is big, rotate with slower speed, the water body that drives in a big way rolls, and its blade is arranged on the water body periphery that small impeller 7 rolls, therefore it is except self playing certain oxygenation, bigger effect be through small impeller 7 oxygenation water body push the four directions to, rapidly diffusion has improved the scope of oxygenation water body greatly.The impeller of two different types friction speeds is formed best combination, has both brought into play strong point separately, remedies the other side's deficiency again, improves oxygen transfer rate and oxygen transfer efficiency effectively, has saved the energy.
