However, the following embodiments are only preferred embodiments of the present invention, not all of them. . Based on the examples in the implementation manners, other examples obtained by those skilled in the art without creative work shall fall within the protection scope of the present invention.
[0022] The specific embodiments of the present invention will be described below in conjunction with the drawings.
[0023] Such as Figure 1-4 As shown, an oxygen supply device for container fish farming includes an oxygen dispenser 1, which is characterized in that: the outlet end of the oxygen dispenser 1 is fixedly connected to the upper end of the air pipe 4, and the top of the air pipe 4 is fixedly provided with a feeding pipe 3 for feeding One end of the pipe 3 extends into the gas pipe 4, and the other end of the feeding pipe 3 extends to the outside of the gas pipe 4 and is fixed to the funnel 2. The gas pipe 4 is provided with a number of air outlets 6 along the length of the gas pipe 4, and the gas pipe 4 has a sliding sleeve An upper sleeve 5 is provided. The side of the upper sleeve 5 is threadedly connected with a screw 8, and the screw 8 abuts on the air pipe 4. The upper sleeve 5 is fixedly sleeved with a top plate 10, and under the top plate 10 is provided to enclose the air pipe 4 The top of the feed tube 12 is fixedly connected to the bottom surface of the top plate 10, the bottom of the feed tube 12 is fixedly provided with a bottom plate 22, the center of the bottom plate 22 is fixedly provided with a middle sleeve 13 which is slidably sleeved on the air pipe 4 , The upper part of the feed barrel 12 is provided with a plurality of feed outlets, a protective net 11 is fixed on the feed outlet, a discharge pipe 9 is arranged on the top plate 10, and a sealing cap 7 is screwed on the discharge pipe 9.
[0024] A water filter plate 14 is provided under the bottom plate 22. The top surface of the water filter plate 14 is fixed to the bottom surface of the bottom plate 22 through a plurality of connecting rods 23. The water filter plate 14 is in a downwardly concave arc shape, and the center of the water filter plate 14 is provided with a circular shape. Opening 24, the air pipe 4 is slidably sleeved in the circular opening 24, a number of short pipes 20 are fixed through the water filter plate 14, the upper end of the short pipe 20 is fixed to the second funnel 19, and the lower end of the short pipe 20 is connected to the connecting pipe 18. Threaded connection, the lower end of the connecting pipe 18 is fixedly connected and communicated with the residual material collection bag 21. A number of permeable meshes are provided on the residual material collection bag 21. The bottom center of the water filter plate 14 is fixedly provided with a lower sleeve 15 and a sliding sleeve of the lower sleeve 15 It is arranged on the air pipe 4, and a limit disk 16 is fixed at the bottom end of the air pipe 4.
[0025] A cavity interlayer 25 is arranged inside the water filter plate 14, and a plurality of air outlet pipes 17 communicating with the cavity interlayer 25 are fixedly arranged on the top surface of the water filter plate 14.
[0026] Working principle: Start the oxygen dispenser 1, and blow oxygen into the water in the fish-breeding container through the air outlet 6 through the air pipe 4. While the oxygen is being blown in, feed the air into the air pipe 4 through the feeding pipe 3 to make the feed follow. The air is synchronously discharged from the air outlet 6, so that a set of equipment can be used to simultaneously realize oxygen and feed feeding.
[0027] Part of the feed discharged from the air outlet 6 enters the feed barrel 12. This part of the feed is continuously discharged from the protective net 11 with the disturbance of the air discharged from the air outlet 6, thereby avoiding the conventional one-time throwing of feed, resulting in a large amount of feed It happens that it sinks to the bottom without being eaten by fish.
[0028] The bulging air accumulates at the bottom of the top plate 10 and drives the top plate 10 to rise under the action of buoyancy, thereby driving the water filter plate 14 to rise synchronously, so that water flows through the short pipe 20, the connecting pipe 18, and the residual material collecting bag 21 to the bottom of the water filter plate 14. Circulation, the feed that is not eaten by fish during the circulation process is trapped in the residual material collection capsule 21, thereby effectively collecting the residual feed, and preventing these feeds from remaining in the water and polluting the water quality.
[0029] During the ascent of the water filter plate 14, part of the air enters the cavity interlayer 25 through the air outlet 6, and then is discharged through a number of air outlet pipes 17 on the water filter plate 14, thereby effectively expanding the oxygen supply range.
[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the description are only preferred examples of the present invention, and are not used to limit the present invention, without departing from the spirit and scope of the present invention. Under the premise, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the claimed invention. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
