Description
Whirlpool jet composite aerator is oxygenation or the aerator in a kind of aquaculture and the waste water treatment industry.
The water body of aquaculture because the influence of biological activity oxygen consumption and climatic variation can make the natural dissolved oxygen content in the water drop to the limit that jeopardizes existence such as fishes and shrimps, needs to use oxygen increasing equipment artificially to water body supply oxygen this moment.In addition, in waste water treatment industry, also use aerator, be commonly referred to aerator.The kind and the pattern of aerator are various, and using then is the mechanical type aerator comparatively widely, and kinds more than ten such as vane type, Waterwheel-type, jetting type, water jet, inflatable are arranged at present.With the position of equipment oxygenation mechanism with respect to water body, the two big classes that are divided into still all right, promptly surperficial aeration-type and aeration-type under water, vane type, Waterwheel-type and water jet etc. belong to the former, jetting type and inflatable then belong to the latter.From national all kinds of aerator performance in 1984 unified test, the result that appraises and chooses excellent: the dynamic efficiency of paddle aerator is 1.2～1.8kgo
2/ kwh, Waterwheel-type are 0.98～1.3kgo
2/ kwh, water jet be 0.53～0.68kgo
2/ kwh, and jetting type or to penetrate the formula of stirring be 0.22～0.62kgo
2/ kwh.Suggestion in the unified test report: develop new product, old product will update.
The purpose of this utility model provides a kind of molten water surface oxygenation and oxygenation under water is one, and the zone of action is big, simple in structure, vibrating noise is little, oxygen transfer efficiency is high, and new-type oxygen-increasing equipment applied widely is realized the update of product.
According to gas as can be known, to " double-film theory " of liquid migration mobility mainly with gas and liquid two-phase between contact surface and exchange process in liquid phase to lose oxygen gradient relevant.Therefore, for developing aerator rational in infrastructure, well behaved, development person competitively makes great efforts " smashing bubble " and stirs water body with strength and strengthen mixing.The turbine type impeller that the utility model adopts the whirlpool of being made up of power transmission shaft, the pump housing, pump cover, turbine type impeller etc. to penetrate pump is first order oxygenation.The characteristics of turbine type impeller be simple in structure, be easy to processing, with a kind of little specific speed turbulence pumps that can run up of composition such as the pump housing, pump cover, power transmission shafts.Turbulence pump is in the process that is converted to the liquid energy by mechanical energy, repeat to have an effect between liquid and the blade, be attended by vortex disturbance mixing phenomena consumingly, though hydraulic efficiency descends, but this phenomenon just in time helps oxygenation mixes, and turbulence pump has good self-priming, air water to mix and the ability of gas-liquid mixture conveying.The lift that utilizes turbulence pump to set up then, the work of two stage jet device after supporting, promptly one-level water～gas promotes, and another grade water～water promotes.Interval one diffusion runner in this two stage jet device.The circulation road that the vortex pump impeller radial outer end is made up of a pump housing and pump cover, upwards first order ejector is installed from the circulation road to spreading the runner immovable fitting, the diffusion runner is upwards installed second level ejector, and downward immovable fitting is installed the bottom outlet pipe from the circulation road.Through the gas liquid mixture that one-level ejector nozzle sprays at a high speed, form one jet entrainment and gas and enter the diffusion runner, be in the gas liquid mixture of turbulent condition, carry out emulsion reaction, increase the contact interface of water and air greatly, promoted the diffusion of oxygen molecule, quickened the dissolved oxygen process.The dissolved oxygen water that this strand reaches the over-saturation state enters second level ejector to carry out the second time and sprays, further emulsification oxygenation, spray at a high speed from nozzle then, the jet entrainment of this moment the oxygen deprivation water that enters from the water sucking mouth of diffusion cover both sides and is mixed in diffusion cover and playpipe, in the emulsification shape over-saturation dissolved oxygen water excessive oxygen with oxygen deprivation water mixed in, be diffused in the oxygen deprivation water and go, make more water become saturated and the over-saturation state, spray in the water body.Half of liquid directly raised into atmosphere like this, splashes to the water surface again, plays the effect of jet water-spraying oxygen-increasing machine.Second half of liquid enters the bottom, pond by the bottom outlet pipe, the bottom water body carried out the oxygen diffusion play water body oxygenation effect.And micro air bubble continues the infiltrate body in floating-upward process, and the middle level water body is carried out oxygen diffusion oxygenation.For the radial load that produces in the conventional turbulence pump of balance, the utility model adopts two intake-outlets, two sections runners, so the corresponding water inlet in a position is arranged respectively on the pump housing, pump cover, and by screw one group of water inlet suction modulation device of being made up of water-logged base, inlet valve is installed at the pump cover water inlet.There is a pair of oblong suction hole the water-logged base both sides.The inlet valve location of being made up of air-breathing valve seat, air-breathing valve pocket, air-breathing spool is fastened in the water-logged base, and the valve of the air-breathing valve seat of tubulose extends water-logged base both sides suction hole horizontal centerline.In the air-breathing valve pocket, the front portion tightly is enclosed within on the inlet valve, afterbody has a screwed hole, the screwed hole top has an air admission hole, afterbody to have the air-breathing spool of externally threaded suction and threaded engagement to regulate the gap of air-breathing spool top cone and inlet valve air inlet, adjusting suction air capacity.The upper end of threeway is tightly overlapped in air-breathing valve pocket bottom, and an end of threeway connects pipe to the water surface, sucks air and enters the pump housing thus.The lower end of threeway can regulate the inlet valve core and inlet valve air inlet gap is blocked with plug screw to the appropriate location.
Because the utility model has been cancelled the deceleration device of common aerator, directly drive by electromotor, mechanical efficiency height, running are steadily, noise is low, the oxygenation scope is big, oxygen transfer efficiency is high.Because its mode of action is multistage mixing oxygenation, so its dynamic efficiency can reach 2.0～2.6kgo
2/ kwh.The whirlpool jet composite aerator of power 2.2kw motor generally can be applicable to 5～7 mu of water surfaces for aquaculture.
