Abstract
Description
Technical Field
[0001] This invention relates to the field of aquaculture technology, specifically to a flow-propelling oxygenation device. Background Technology
[0002] In aquaculture, if there is insufficient oxygen in the ponds, aquatic species are prone to disease and even death. Since feed and aquatic excrement can easily lead to low dissolved oxygen levels in ponds, existing aquaculture farms use aeration devices to increase the dissolved oxygen content.
[0003] Existing aeration equipment generally suffers from a single aeration function, with only one air inlet chamber and one air inlet pipe. When aerating water, the impeller only outputs air at the front end under negative pressure. The water and air are not fully mixed and cut by the bubbles before being pushed, resulting in low aeration efficiency. The dissolved oxygen value of the aquaculture water is not effectively improved, which can easily cause severe hypoxia and death of aquatic animals in the aquaculture water. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a propulsion oxygenation device that solves the problems mentioned in the background section.
[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, more specifically, a flow-propelling oxygenation device includes a motor, a connector fixed to the top of the motor, a second air inlet pipe connected to the front of the outer surface of the connector, a vertical pipe inserted into the top port of the connector, a first air inlet pipe connected to the upper surface of the outer surface of the vertical pipe, a motor shaft sleeve provided below the interior of the second air inlet chamber, a water impeller inserted into the top of the motor shaft sleeve, and three blades welded to the outer surface of the water impeller above the vertical pipe.
[0006] Furthermore, a water seal and air seal ring are fitted above the outer surface of the motor shaft sleeve, and several through-holes are opened on the outer surface of the motor shaft sleeve below the water seal and air seal ring.
[0007] Furthermore, the interior of the vertical pipe is configured as a first air inlet chamber above the water seal air seal ring, and the interior of the vertical pipe, below the water seal air seal ring, inside the connector, and inside the motor shaft sleeve are configured as a second air inlet chamber. The top port of the vertical pipe is opened as a first circumferential air outlet, and the top port of the water impeller is configured as a second circumferential air outlet.
[0008] Furthermore, the top end of the motor output shaft extends through the interior of the connector and is fixedly connected to the bottom end of the motor shaft sleeve.
[0009] The beneficial effects of the propulsion oxygenation device of the present invention are as follows:
[0010] (1) This invention solves the problem that traditional push-flow oxygenation equipment generally has a single oxygenation function, with only one air inlet chamber and one air inlet pipe. When pushing water to oxygenate, the water impeller only outputs air at the front end under negative pressure. The water and air are not fully mixed and the bubbles are cut before pushing the flow, resulting in low oxygenation efficiency. The dissolved oxygen value of the aquatic water body cannot be effectively improved, which can easily cause severe hypoxia and death of aquatic animals in the aquatic water body.
[0011] (2) The device of this invention has multiple functional options: 1. Simultaneous use of dual air chambers and dual air pipes. 2. High-speed cutting using mixed air bubbles in a single air chamber and a single air pipe. 3. Traditional water-air mixing using a single air chamber and a single air pipe. 4. Microbubbles can be generated by adjusting the air intake (a small amount of air) using the air intake regulating valve of the first air chamber.
[0012] (3) When the present invention selects the dual-air chamber interconnection dual-effect air output and the dual-effect push flow oxygenation mode with air output at the rear end and front end of the water impeller, the effect is increased by 50% compared with the traditional push flow oxygenation equipment. Moreover, the water and air are mixed more fully, which effectively improves the value of the oxygenation equipment. It is also suitable for the high dissolved oxygen value requirements of aquaculture water bodies required by modern high-density aquaculture, and achieves the purpose of high efficiency and energy saving.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.
[0020] like Figure 1-4As shown, according to one aspect of the present invention, a propulsion oxygenation device is provided, including a motor 1, a connector 2 fixed to the top of the motor 1, a second air inlet pipe 3 connected to the front of the outer surface of the connector 2, a vertical pipe 4 inserted into the top port of the connector 2, a first air inlet pipe 5 connected to the upper surface of the outer surface of the vertical pipe 4, a motor shaft sleeve 6 provided at the lower part of the interior of the second air inlet chamber 12, a water impeller 8 inserted into the top of the motor shaft sleeve 6, a water seal air seal ring 7 sleeved on the upper surface of the outer surface of the motor shaft sleeve 6, three blades 9 welded to the outer surface of the water impeller 8 above the vertical pipe 4, a regulating valve can be installed on the first air inlet pipe 5 for adjusting the air intake, and a plurality of through-type air outlet holes 10 opened on the outer surface of the motor shaft sleeve 6 below the water seal air seal ring 7.
[0021] In this embodiment, the interior of the vertical pipe 4 above the water seal air seal ring 7 is set as the first air inlet chamber 11, and the interior of the vertical pipe 4 below the water seal air seal ring 7, the interior of the connector 2, and the interior of the motor shaft sleeve 6 are set as the second air inlet chamber 12. The top port of the vertical pipe 4 is opened as the first circumferential air outlet 13, and the top port of the water impeller 8 is set as the second circumferential air outlet 14.
[0022] When in use, you can choose to cancel the installation of the water seal air seal ring 7, which will allow the first and second air chambers to communicate with each other for dual oxygenation. If the water seal air seal ring 7 is installed, the first air inlet chamber 11 and the second air inlet chamber 12 will not communicate with each other. After closing the air inlet pipe of the other air chamber, air can be introduced into a single air chamber. If the air inlet regulating valve at the air inlet pipe of the first air inlet chamber 11 is used alone to introduce a small amount of air, the air will be discharged through the first circumferential air outlet 13. The bubbles generated by the high-speed water meter body at one end of the water impeller contacting and rubbing with the air will be pushed out by the high-speed cutting of the bubbles by the water impeller, which are microbubbles (the smaller the air intake, the finer the bubbles).
[0023] In this embodiment, the top end of the output shaft of the motor (1) extends through the inside of the connector (2) and is fixedly connected to the bottom end of the motor shaft sleeve (6), so that the motor 1 operates to drive the water impeller 8 to rotate.
[0024] The working principle of this invention is as follows: The air outlet of the first air inlet chamber 11 can be used as a separate oxygenation unit. The water seal and air seal ring 7 between the first air inlet chamber 11 and the second air inlet chamber 12 isolate the two air inlet chambers and prevent them from communicating with each other. When the water impeller 8 rotates at high speed to push water, under the action of negative pressure, air enters through the first air inlet pipe 5, passes through the air chamber, and is then diverted to the circumferential air outlet for the water impeller 8 to carry out and mix with water for propulsion.
[0025] When the water impeller 8 rotates at high speed, under the action of negative pressure, the second air inlet pipe 3 draws in air into the second air inlet chamber 12, and then through several air inlet holes of the double-effect water impeller 8 in the second air inlet chamber 12, it is transported to the second circumferential air outlet 14 of the double-effect water impeller 8 to mix with water and propel the flow.
[0026] When the intake valve of the first intake pipe 5 is adjusted to a very small amount, the gas entering under the negative pressure of the water impeller is output through the first circumferential outlet 13 and generates friction with the water meter body of the high-speed rotating water impeller 8 to form mixed bubbles. After being cut by the high speed of the water impeller 8, it becomes water-air mixed microbubbles (Note: the smaller the intake volume, the finer the bubbles).
[0027] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
