Therefore, they should not be construed as limitations on this utility model.
[0022] The dissolved oxygen cone disclosed in this utility model is mainly used in fish pond oxygen supply scenarios.
[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A dissolved oxygen cone for fish farming includes a dissolved oxygen cone 1, an inlet pipe 2 installed at the top of the dissolved oxygen cone 1, and an oxygenation pipe 3 installed on the side of the top of the dissolved oxygen cone 1. A mixing mechanism 6 is provided at the bottom of the dissolved oxygen cone 1.
[0024] The mixing mechanism 6 includes a base 601 fixedly installed at the bottom of the dissolved oxygen cone 1. A motor 602 is fixedly installed at the bottom of the base 601. The output end of the motor 602 extends vertically into the interior of the base 601 and is connected to an agitator 603. The agitator 603 is distributed inside the base 601. A port 604 is opened on one side of the agitator 603. An oxygen pump 605 is fixedly installed on the outer side of the base 601. Several oxygen inlets 606 are opened through the side wall of the base 601. The oxygen inlets 606 are irregularly staggered along the outer side of the base 601. The oxygen pump 605 and the oxygen inlets 606 are connected through each other. At the same time, the agitator 603 blocks the side of the oxygen inlet 606.
[0025] In this embodiment: When supplying oxygen to the fish pond, the operator connects the water inlet pipe 2 at the top of the dissolved oxygen cone 1 to the external water guiding device, and simultaneously connects the oxygenating pipe 3, the oxygenating outlet 605, and the external oxygen supply device. Water is introduced into the interior of the dissolved oxygen cone 1 through the water inlet pipe 2, and oxygen is introduced into the interior of the dissolved oxygen cone 1 through the oxygenating pipe 3. Utilizing the special cone structure of the dissolved oxygen cone 1, and with the help of the positive and negative pressure (atmospheric pressure) working mode, the oxygen is initially dissolved in the water. The oxygenated water that has completed the initial dissolution enters the interior of the base 601. At the same time, the motor 602 drives the stirring blade 603 to rotate, stirring the oxygenated water inside the base 601. Meanwhile, the oxygen inlet 606 and the port 604 on the side of the stirring blade 603 are intermittently aligned. At this time, the oxygen inside the oxygenator 605 can be injected into the base 601 through the port 604, thereby impacting the oxygenated water. In conjunction with the operation of the agitator 603, the dissolved oxygen rate of the water flow is further improved. A guide pipe 5 is connected between the bottom of the base 601 and the dissolved oxygen cone 1. A water outlet 607 is opened through the side wall of the base 601. The water outlet 607 and the guide pipe 5 are symmetrically distributed. A base 8 is fixedly installed at the bottom of the base 601. The motor 602 is distributed inside the base 8. The water flow that has completed the initial oxygenation inside the dissolved oxygen cone 1 can enter the interior of the base 601 through the guide pipe 5. After the water flow inside the base 601 has completed the secondary oxygenation, it can be introduced into the interior of the fish pond through the water outlet 607.
[0026] Reference Figure 1 and Figure 2 In a preferred embodiment, a return oxygen pipe 4 is provided on the side of the dissolved oxygen cone 1, and several one-way valves 7 are provided on the outside of the return oxygen pipe 4. Water is introduced into the interior of the dissolved oxygen cone 1 through the water inlet pipe 2, and oxygen is introduced into the interior of the dissolved oxygen cone 1 through the oxygenation pipe 3. When the oxygen initially dissolves in the water, the oxygen that has not reacted with the clean water will be returned to the top of the dissolved oxygen cone 1 through the return oxygen pipe 4. The operator can control the opening and closing of the return oxygen pipe 4 by rotating the one-way valves 7.
[0027] Working principle: During use, the operator connects the water inlet pipe 2 at the top of the dissolved oxygen cone 1 to the external water guiding device, and simultaneously connects the oxygenating pipe 3, the oxygen pump 605, and the external oxygen supply device. Water is introduced into the interior of the dissolved oxygen cone 1 through the water inlet pipe 2, and oxygen is introduced into the interior of the dissolved oxygen cone 1 through the oxygenating pipe 3. Utilizing the special cone structure of the dissolved oxygen cone 1, and employing a positive and negative pressure (atmospheric pressure) working mode, oxygen is initially dissolved in the water. The initially dissolved oxygenated water then enters the interior of the base 601 through the guide pipe 5. When the motor 602 drives the agitator 603 to rotate, it agitates the oxygenated water inside the base 601. At the same time, the oxygen inlet 606 and the port 604 on the side of the agitator 603 are intermittently aligned. At this time, the oxygen inside the oxygen pump 605 can be injected into the interior of the base 601 through the port 604, thereby impacting the oxygenated water. In conjunction with the operation of the agitator 603, the dissolved oxygen rate of the water flow is further increased. After the water inside the base 601 has completed secondary oxygenation, it will be introduced into the interior of the fish pond through the outlet 607.
[0028] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
