Detailed Description
The core idea of the invention is as follows: the impact aeration is that in the process of pumping gas (air, oxygen, ozone and other gases) into the aeration component for aeration, the aerated liquid (the technical scheme of the invention can be used for river water, lake water, sewage, garbage penetrating fluid, wine, milk and other liquids) impacts the surface of the aeration component to obtain micron-sized (the diameter is between 5 microns and 50 microns) and even nano-sized bubbles (the diameter is less than 5 microns). The invention further controls the size of aeration bubbles by controlling the speed of the liquid to be aerated impacting the surface of the aeration component. The greater the velocity of the aerated liquid impacting the surface of the aeration member, the smaller the aeration bubbles. The invention can further rotate the aeration component in the aeration process, so that the bubbles generated by aeration are smaller.
The principle of the impact aeration in the invention is as follows: the air flow emerges from the micropores, and the liquid on the surface of the aeration part flows in a direction vertical to the emerging direction of the air flow because the aeration part is impacted by the liquid, so that the air flow is cut to form bubbles just after emerging a little. The faster the liquid impact velocity, the faster the night flow velocity at the surface of the aeration member, the greater this cutting force and the faster the cutting frequency, the shorter the "air column" that is "cut" and therefore the smaller the air bubbles. When the aeration part rotates in the aeration process, the liquid flow speed on the surface of the aeration part is faster, and the generated bubbles are smaller.
The smaller the bubbles are, the larger the specific surface area is, the higher the gas utilization rate is, and the lower the aeration cost is. In addition, the micron-sized bubbles have strong air floatation effect and can support and float blue algae and the like so as to be beneficial to quick removal; the smaller the oxygen bubbles are, the stronger the oxidation effect is, and the more beneficial the purification of the liquid is; the nano-sized bubbles can also inhibit bacterial viruses. The aerator with the shell is combined with the robot, and intelligent aeration can be realized.
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of a first embodiment of the present invention, and as shown in fig. 1, the aerator includes: an aeration section 101; a connecting part which comprises a plug 102 and a gas pipe 103; a power plant comprising a submerged motor 104 and blades 105; a cylindrical case 106; in addition, a filter screen 107 and a power cord 108 are included.
The connecting part is used for connecting the gas supply device and the aeration part to send the gas delivered by the gas supply device into the aeration part; the power device makes the liquid impact the surface of the aeration component. The cylindrical housing 106 has a liquid inlet and a liquid outlet, and the power device, the aeration part 101 and the connecting part are sequentially and centrally fixed in the housing, wherein the power device is close to the liquid inlet.
The aeration part 101 according to the first embodiment of the present invention is a tube made of a microporous material having one end into which gas is introduced through a connection part and the other end closed, and the microporous material may be of various materials, as long as there are micropores in the material, the smaller the micropores themselves, the better. The closed end of the aeration component is a smooth curved surface protruding outwards.
The connection part of the first embodiment of the present invention is a plug 102 and a gas pipe 103 connected to a gas supply device. The air inlet of the aeration part 101 is connected with the air pipe 103 through the plug 102, namely the air pipe 103 is connected to the plug 102, and the plug 102 is connected to the air inlet of the aeration part 101. In the present embodiment, the aeration member 101 does not rotate.
The power device of the first embodiment of the invention is a submerged motor 104 which is positioned on the front surface of the closed end of the aeration part and can change the rotating speed, and blades 105 which are driven by the submerged motor 104 to rotate so as to push the liquid to flow and enable the liquid to impact on the surface of the aeration part 101, and the submerged motor 104 is input with electric energy through a power cord 108. By varying the rotational speed of the submerged motor 104, the speed at which the liquid impacts the aeration member 101 can be varied, thereby affecting the size of the bubbles produced. The central axis of the aeration part 101 is required to be aligned with the rotating shaft of the paddle 105, so that the liquid flow can impact the surface of the aeration part 101 more fully.
The cylindrical housing 106 of the first embodiment of the present invention may be cylindrical, square cylindrical, elliptical cylindrical, or the like. The liquid inlet of the cylindrical housing 106 may be processed into a flat shape, even if the height of the liquid inlet is reduced and the width of the liquid inlet is increased, so as to be suitable for a shallow liquid region or avoid submerged objects (such as submerged animals and plants) as much as possible, of course, the liquid inlet of the cylindrical housing 106 may also be processed into a circular shape, and in addition, a wire mesh 107 may be installed on the liquid inlet to prevent impurities from entering the interior of the cylindrical housing 106. The liquid outlet of the cylindrical housing 106 can be processed into a circular shape, and the cross-sectional area of the inner cavity of the liquid outlet can be reduced, so that the flow velocity of the aerated liquid is increased. It is also possible to provide the cylindrical housing 106 with a plurality of liquid outlets each directed in a different direction so as to allow a larger range per unit time of the aerated bubble-containing liquid.
In all embodiments of the present invention having a housing, the inner cavity of the housing may also be designed in the shape of a venturi tube, and fig. 2 is a schematic structural view of an embodiment of the aerator according to the present invention in which the inner cavity of the housing is in the shape of a venturi tube. As shown in fig. 2, when the inner cavity of the cylindrical housing 206 is venturi-shaped, the inner cavity of the cylindrical housing 206 has a smaller cross-sectional area at the portion overlapping the aeration member 201 than at other portions, so that when the liquid in the housing 206 flows near the aeration member 201 under the action of the submerged motor 204 and the paddles 205, the liquid flow rate increases because the inner cavity of the cylindrical housing 206 has a smaller cross-sectional area at this point, and the larger liquid flow rate increases the impact effect when the gas enters the aeration member 201 through the gas pipe 203 and the plug 202 for aeration. The inner cavity of the cylindrical shell 206 is arranged in a venturi shape, so that the liquid flow rate at the aeration part 201 can be increased or the pressure on the surface of the aeration part 201 can be changed to generate smaller bubbles under the condition of the same energy consumption, or more energy can be saved under the condition of generating more bubbles with the same size.
In addition, the inner wall of the cylindrical shell according to the first embodiment of the present invention may have a spiral streamline shape to reduce the inner cavity drag coefficient as much as possible.
In a second embodiment of the invention, the means for forcing the liquid to impinge on the surface of the aeration means is an immersed pump having a liquid outlet facing the aeration means of the aerator for impinging the liquid on the surface of the aeration means.

The aeration amount of the aerator in unit time can be increased by adopting the aeration group 302, and simultaneously, the impact liquid flow generated by the power device is more fully utilized. The other parts of the third embodiment of the present invention are the same as those of the first or second embodiment of the present invention, and will not be repeated here

When power devices 405 and 406 cause liquid to impinge on the surface of aeration member 401, the flowing liquid simultaneously causes aeration member paddles 404 to rotate aeration member 401 about its axis. Other parts of the fourth embodiment of the present invention are the same as those of the first embodiment or the second embodiment of the present invention, and will not be repeated here.

The other parts of the fifth embodiment of the present invention are the same as those of the first, second or fourth embodiment of the present invention, and will not be repeated here.
Referring to fig. 6, fig. 6 is a schematic structural view of an embodiment of the aerator according to the present invention, in which the aerator uses a motor as power to rotate the aerator, and as shown in fig. 6, the power device for making liquid impact the surface of the aerator 601 is a submerged motor 602 with variable rotation speed and a paddle 604 mounted on its rotating shaft 603 and rotating with the rotating shaft. Meanwhile, the rotation shaft 603 of the submerged motor 602 is connected to the closed end of the tubular aeration member 601 made of a microporous material through a stopper 605. That is, the motor shaft 603 is connected to the plug 605, and the plug 605 is connected to the aeration member 601. At the air inlet end of the aeration part 601, an air pipe 606 is connected to the air inlet of the aeration part 601 through a submerged seal bearing 607.

By varying the rotational speed of the submerged motor 602, the speed at which the liquid impacts the aeration member 601 may be varied, thereby affecting the size of the bubbles produced. The other parts of the sixth embodiment of the present invention are the same as those of the first embodiment of the present invention, and will not be repeated here.

The aerator tubular housing 701 is fixed to the fixing shaft 702 in a direction perpendicular to the vertical axis of the fixing shaft 702, but it is also possible to perform the same operation as long as the angle between the axis of the aerator tubular housing 701 and the axis of the fixing shaft 702 is not zero even if the axis of the aerator tubular housing 701 and the axis of the fixing shaft 702 are not perpendicular. Thus, in the aeration process, the fixed shaft 702 can also drive the aerator to rotate in the liquid, so as to realize mobile aeration and enlarge the aeration influence range.

The fan 804 in this embodiment is fixed to a stationary column 806 in the liquid by a bearing 805, and the fan 804 may be located above or below the liquid. The blower 804 is connected with the aerator housing 801 through a traction rope 807.
