Air contact aerator power consumption is big, and energy conversion efficiency is low.Many aerator manufacturers all continuous transformation, Amendment impeller parameters promote water body efficiency so that impeller is in many styles in the market to improve, but restricted by design concept (and The design concept of water body is directly stirred under the working environment of ingress of air by impeller) it is difficult big breakthrough.It is basic former Because being:

Impeller rotation with water body contact process in, impeller be exposed in air environment directly water body is sported from static state it is dynamic State, water body, air, impeller triple interaction generate bubble, punching bubble is crumbled and fall because of the change of water body pressure again caused by It hits, vibrates the in-fighting of formation, form the spray of sputtering shape, reduce the contact surface of impeller and water body, it cannot be completely by motor Power, which is converted to, sheds acting to water body.Therefore air contact aerator all has reduction gearbox, and purpose is exactly to reduce impeller Revolving speed reduces the generation of bubble, impeller is allowed effectively to contact with water body, therefore improves the cost of such aerator, manufactures work Skill, and electric energy can be lost for reduction gearbox and wheel speed is too low, the distance for spraying water body will reduce, and the area in oxygenation waters will (water spray distance is bigger more advantageous for high-density fish culture, and the unit space that anoxic shoal of fish individual pours into oxygenation water body will be more for reduction Greatly, the individual of anoxic is made to obtain oxygen supply rapidly).

Impeller accelerates injection direction when water body excessively to dissipate, and water body water spraying direction, which excessively dissipates, will lead to water body in air Total flying distance reduce, water body and air contact surfaces will reduce, that is, reduce the dissolved oxygen efficiency of water body, and directly result in oxygenation The reduction of water surface area.

Air insulated formula aerator has pump body structure, and working efficiency is directly restricted by pump housing efficiency.And improve pump housing effect One important channel of rate is exactly the regurgitant volume for reducing water body in the pump housing, this part water body consumes electric energy.Flowed in the pump housing The water body (high-pressure side water body, i.e. water discharging direction) of the pump housing pumps intracorporal water body (low-pressure side water body, i.e. water suction direction) to inflow out Direction reflux.This defect be in the pump housing between impeller and pump case there are gap, this gap can only reduce, and can not eliminate, i.e. impeller There is relative motion (impeller will rotate) between pump case to meet pump housing requirements of one's work, and this gap can lead to it is a series of Negative technical characteristic: gas is turbid, impact, noise, construction chemical attack impeller, pump case condition.

Air contact aerator: motor is using air cooling way heat dissipation, motor not by sealing water-proofing treatment, motor quilt Pontoon is maked somebody a mere figurehead on the water surface, therefore air contact aerator is big with volume, it is inconvenient to install and use, if air contacts Formula aerator is overturned by unexpected in the water surface at work, since motor is not over the motor for sealing water-proofing treatment, leading to energization Water inlet will cause the extremely hazardous safety accidents such as electric shock.

Air insulated formula aerator, complete machine suspends and the water surface, the only water outlet of exposed floating drum 151,152 and spray head 23 on the water surface Mouthful, and air contact aerator complete machine by floating ball 15 (or pontoon) set up with the water surface on, directly occupy the field of the water surface or more Ground space, under Same Efficieney environment: the volume of the equipment of itself of air contact aerator is greater than air insulated formula oxygenation Machine from volume, therefore air insulated formula aerator technical solution be more suitable for needing to save space-efficient application environment.

And relative to existing air insulated formula aerator, Same Efficieney in the case of: since this programme is without reflux impeller Structure superiority, air insulated formula aerator, the machine volume that this programme can provide micro high efficiency can accomplish, such as: 20 cubic centimetres of space sizes or less than 20 cubic centimetres space sizes；Since existing space isolation aerator has water pump Structure and use existing air insulated formula aerator technical solution, such as: when machine volume accomplishes 20 cubic centimetres of space sizes, The working efficiency of the pump housing reduces, and conversion ratio reduces, and accessory requirement is more accurate, and processing and manufacturing difficulty is increased sharply, manufacturing cost Also it improves.Therefore this programme is relative to existing air insulated formula aerator is more creative and practicability: the more energy efficient, service life is more It is long, volume is smaller etc., more can adapt in the oxygenation environment for using aerator the restricted requirement of occupied space.

In summary: the advantages of technical solutions of the utility model, is:

(1), by adopting the above-described technical solution, this can guarantee to enter impeller without impeller is flowed back when shedding water body Water body, except be attached to without reflux impeller internal cavity water droplet in addition to, remaining water will all by without reflux impeller acting be shed out The water surface can be sprayed the water for entering the unit volume without reflux impeller without reflux impeller with the water of unit volume.It goes In addition to the reflux defect of air insulated formula aerator, i.e. conventional leaf wheel pump (such as: axial flow pump, centrifugal pump) impeller (centrifugation leaf Piece or propeller blade) and pump case between gap caused by negative technical characteristic: reflux, gas is turbid, impact, noise, constructionization The design defect for learning the condition of corrosion impeller, pump case improves this without the reflux service life of impeller, electric flux conversion ratio.

(2), the acceleration water body that can be oriented makes water body have single spray angle, solves air contact oxygenation Machine accelerates the divergence problem of water body, expands the area in oxygenation waters, enhances the dissolved oxygen efficiency for contacting water body with air.

(3), can smoothly accelerate water body in the case where completely cutting off air conditions, reduce accelerate water body because air participation caused by In-fighting idle work caused by oscillation, impact improves impeller and accelerates water body that water body is made to sport dynamic energy turn from static state Rate improves the efficiency that electric energy is converted to water body kinetic energy.

(4), power-adjustable is wide, can produce big water yield, big sprayed fiber concrete without reflux impeller, improve this aquatic products and support Grow the adaptability of the use scope of aerator.

It (5), is an entity, i.e. extension, first shell, second shell, centrifuge blade, spiral shell without reflux impeller due to this Revolving paddle (propeller can be omitted) is a connected entity, has stronger mechanical strength, relative to existing on the service life Air insulated formula aerator has biggish advantage, and the manufacture of no reflux impeller can be completed by one procedure of mold, due to this nothing Than existing air insulated formula aerator in the case of the compact constructed air insulated formula aerator of the blade wheel structure that flows back, Same Efficieney Volume is smaller, accessory is less, the manufacturing cycle is shorter, with more versatility, performance stablize, longer life expectancy, thus manufacturing cost, Technique, service life have on job stability and have great advantage.
