Abstract

A lifting type water oxygenation circulation promoting device comprising a lifting pipe of a water inlet and a water outlet is characterized in that: an aerator consisting of an aerator head and an air supply pipe is arranged on the water inlet of the lifting pipe, and the aerator head is provided with a tube union connected with a compressor exhaust pipe. The design principle is that: compressed air is led to an air sprayer and sprays out through an exhaust hole to form a plurality of air bubbles in water, the oxygen partial pressure in every bubble is higher than the dissolved oxygen partial pressure in water, and oxygen enters water through gas-water interfaces, thereby improving dissolved oxygen content in water for treatment. The pumping device which integrates pump function and aerator function with scientific design, simple and rational structure can not only meet the water circulation lifting requirement for growth of aquatic products but also meet the requirement of oxygenation in aquaculture waters. The dual functional lifting type water oxygenation circulation promoting device has a good energy-saving effect.

Description

The short circulation device of oxygenation in the hoisting type water

Technical field

The utility model relates to a kind of water treatment system or landscape water round-robin device of being used for, especially a kind of have a short circulation device of oxygenation in the hoisting type water that increases oxygen in water.

Technical background

At present, having a lot of occasions all to need to be provided with water treatment system in daily life promotes the water in the pond, to realize the movable or circulation down waterborne in the pond, help aquatic plant or biological growth, as: fish jar water cycle etc. is viewed and admired by aquaculture or family, realize that the sole mode that this water is carried is to rely on the vane type water pump, the vane type water pump is by motor, the impeller that is provided with the pump case of intake-outlet and is arranged in the casing is formed, its principle of work and process are: by the middle wheel high speed rotating in the electric motor driving casing, make between the water-in of casing and water outlet and produce pressure reduction, thereby realize the conveying of the suction of low level water to the water of high position discharging.This vane type water pump can satisfy the water of a lot of occasions and carry requirement, and the efficient height.But the water delivery function that it is simple can not satisfy aquaculture pond or view and admire both needs water cycles of fish jar, needs the breed needs of oxygen supply in water simultaneously.As everyone knows, the oxygen that the growth needs of the animal and plant in the water is enough, when water body dissolved oxygen insufficient the time, means that must be by artificial aeration's oxygen supply are to meet the demands under natural ecological environment.Traditional method is to promote pending water and employing aerator aeration with submersible pump.But the water pump of big flow to selecting little pressure head whenever in the design is difficult to find suitable model on the market, selects the water pump of excessive pressure head to cause waste on the energy; The efficient of the aerator on the market is generally all lower in addition, and at shallow water position aeration, the duration of contact of bubble and pending water is short, and dissolution rate of oxygen is low, wastes energy.

Summary of the invention

The purpose of this utility model is the deficiency that exists in the above-mentioned traditional design, a kind of low power consuming is provided and can satisfies water to promote requirement, can increase the short circulation device of oxygenation in the hoisting type water of oxygen in water again.

The short circulation device of oxygenation in the hoisting type water of the present utility model, comprise: the riser tube that is provided with water-in and water port, it is characterized in that: the nearly water-in of riser tube position is provided with an aerator that is made of aeration head and pneumatic tube, aeration head be provided with can with the tube stub of compressor air-discharging pipe coupling.

The principle of design of the short circulation device of oxygenation is in the utility model hoisting type water: pressurized air is guided to jet thrust spray through venting hole, in water, form countless bubbles, bubble is because of gently rising in riser tube, pending water reduces because of being full of bubble density in the riser tube, form pressure difference outward with riser tube, the result makes pending water lifting in the riser tube, bubble and water are in lifting process, oxygen partial pressure in the bubble is higher than the dissolved oxygen dividing potential drop in the water, oxygen sees through air-water interface and enters in the water, thereby the dissolved oxygen content in the raising water, form a kind of air water mixed solution, therefore the water dissolution oxygen level of discharging from the riser tube water port is higher than general water far away, and it is moving in the water that the current of high-solubility oxygen content more are of value to undoubtedly, the growth of plant.

The short circulation device design science of oxygenation in the utility model hoisting type water, simple and reasonable for structure, during use, described riser tube can be lower than the water surface, also can be higher than the water surface, the riser tube that is lower than the water surface all can satisfy the lifting of water and add oxygen demand with the riser tube that is higher than the water surface, has tangible pump water function but be provided with this device that is higher than water surface riser tube.This device had both satisfied the required water cycle lifting requirement of animal and plant growth in the water, had satisfied again for culturing the requirement of the continuous oxygenation in waters.The device of this two-in-one function has good energy-saving effect.

The concrete structure of the short circulation device of oxygenation is provided in detail by the following drawings and embodiment in the utility model hoisting type water.
