Abstract
A mixed stirring underwater aerator comprising an air supply pipe of a tube union connected with a compressor exhaust pipe and a bracket is characterized in that: an aerator head consists of a rotor and aerator pipes spreading over the rotor, and every aerator pipe is provided with air orifices; a motor is arranged on the bracket, one end of the rotor of the aerator head is fixed with the motor shaft, and the other end of the rotor is connected with the air supply pipe. The design principle of the aerator is that: compressed air is led into the rotatable aerator head and sprays into water when the aerator head rotates at high speed with the motor, and the compressed air which has sprayed into water is instantly broken up by the rotating aerator pipes, thereby forming mixture of water and gas and improving dissolved oxygen content in water. With scientific design, simple and rational structure, the mixed stirring underwater aerator is suitable not only for sewage treatment but also for oxygenation in aquaculture waters.
Description
Technical field
The utility model relates to aerating apparatus, especially a kind of stirring-type underwater aerator.
Technical background
At present, adopting pressurized air to squeeze into mode in the pond usually in wastewater treatment and aquaculture waters handles water quality or improves oxygen level in the water.Realize the movable or circulation down waterborne in the pond, help aquatic plant or biological growth, well-known, 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.The aeration tube structure that tradition is used for pressurized air introducing water is very simple, just import in the water with the aeration tube of pressurized air pipe coupling one, the gas that aeration tube discharges forms the bubble that varies in size and rises naturally in water, though this aeration method simple in structure is simple, but because it is bigger usually to enter the bubble that the gas in the water forms naturally, the gas that bubble contacts with water, liquid interface amass less, and therefore, it is undesirable that it improves oxygen in water effect.The efficient of this aeration tube is generally all lower, 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 at above-mentioned aeration tube, and a kind of stirring-type underwater aerator that can increase the oxygen in water mixed effect is provided.
Stirring-type underwater aerator of the present utility model comprises: be provided with pneumatic tube and support with compressor air-discharging pipe connected pipe joint, it is characterized in that: aeration head is made of rotor and the aeration tube that distributes thereon, is equipped with production well on each aeration tube; Motor is installed on the support, and an end of the rotor of aeration head is fixedlyed connected with motor shaft, and the other end of rotor connects pneumatic tube.
The principle of design of the utility model stirring-type underwater aerator is: pressurized air is introduced in the rotatable aeration head, pressurized air sprays in the water under with motor high speed rotating state at aeration head, the instantaneous aeration tube that promptly is rotated of pressurized gas that sprays in the water is broken up, stir the countless microbubbles of formation with water, bubble is because of gently rising in water, water reduces because of being full of bubble density, these bubbles and water are in uphill 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, because this device can produce microbubble, under the identical situation of gas work output, the total area of microbubble is higher than air pocket far away, thereby makes gas, liquid contact interface is long-pending to be increased greatly.Therefore the water dissolution oxygen level of this air water mixed solution is higher than general water far away, and the current of high-solubility oxygen content more are of value to the growth of animal and plant in the water undoubtedly.
The utility model stirring-type underwater aerator design science, simple and reasonable for structure, both be applicable to sewage disposal, also be applicable to the oxygenation in aquaculture waters.
The concrete structure of the utility model stirring-type underwater aerator is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is the structural representation of stirring-type underwater aerator;
Fig. 2 is another stirring-type underwater aerator structural representation.
Embodiment
Embodiment 1: can be clear that from Fig. 1 the stirring-type underwater aerator is by support 1, aeration head 2, motor 3 and pneumatic tube 4 and form.Support 1 is columnar structured, comprises on it being used for the rotor 21 localized lower bracket rings 12 that motor 3 is installed localized upper bracket 11 and is used for aeration head 2; Described aeration head 2 constitutes by rotor 21 with " ten " word shape distribution four aeration tubes 22 thereon, is distributed with production well 23 on each aeration tube 22; Described motor 3 is installed in the center of support 11 on the support 1, and the rotor 21 of aeration head 2 is installed on the motor shaft 31, and rotor 21 is plugged under the cylinder-shaped bracket in the support ring 12 in the clearance fit mode.Be provided with the pneumatic tube 4 of compressor air-discharging pipe connected pipe joint 41 and be connected from rotor 21 end centers insertion fitted seal.
The using method of this stirring-type underwater aerator and working process: the stirring-type underwater aerator is placed in the pond, and its degree of depth must guarantee that aerator is immersed in the water level below.The tube stub 41 of pneumatic tube 4 ends of aeration head 2 is connected with the vapor pipe of air compressor, after starting air compressor, pressurized air is exported by aeration head 2 behind pneumatic tube 4, when motor 3 energising runnings, the rotor 21 that can drive aeration head 2 rotates synchronously, be distributed in aeration tube 22 rotations on the rotor 21, aeration tube 22 is outside emission gases in the fast rotational whipping process, form uniform distribution and the tiny bubble of volume, the generation of micro-bubble increases the liquid gas interface area greatly, has increased the dissolved efficiency of oxygen in water thus; The viscosity of water slows down the microbubble lift velocity in addition, has also increased air water duration of contact, has the effect that improves the gas-vapor mix degree.
Embodiment 2: can be clear that from Fig. 2 this is the fabulous stirring-type underwater aerator of a kind of operation stability, its basic structure is identical with embodiment 1, difference is, be used for the localized support 1 of aeration head 2 installations and be the shaped as frame structure, shaped as frame structure stand 1 is provided with the lower bracket ring 12 that power supply machine is installed localized upper bracket 11 and is used for rotor 21 installations of aeration head 2.Be arranged with two aeration tubes 22 on the rotor 21 of aeration head 2, be distributed with production well 23 on the aeration tube 22.The using method of present embodiment is identical with embodiment 1.
