Description

Technical Field

[0001] The utility model relates to the technical field of micro-bubble aquaculture, in particular to a micro-bubble aquaculture device. Background Art

[0002] Aquaculture is the use of waters available for aquaculture by humans. According to the ecological habits of the aquaculture objects and the requirements for the environmental conditions of the waters, aquaculture techniques and facilities are used to cultivate aquatic economic animals and plants. In the existing aquaculture process, in order to supply oxygen to the internal water bodies, aeration devices are generally used for aeration;

[0003] Traditional aeration devices are generally composed of an aeration plate or an aeration plate and a hole body opened on its upper end surface. In existing aquaculture devices, especially some larger aquaculture devices, the aeration part is fixed, which leads to poor aeration uniformity and uneven oxygen concentration in the overall water body, which is easy to affect the internal aquatic products. During the aquaculture process, some food residues and impurities are easy to settle, and the aeration device is generally not started all the time. When it is not started, the settled impurities and debris are easy to enter the aeration disk and the inner wall of the hollow plate through the aeration holes. Over time, the aeration part may be blocked. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a micro-bubble culture device, which can effectively improve the uniformity of aeration during use.

[0007] Preferably, the moving mechanism includes a motor installed on the left side of the shell, the output shaft of the motor extends into the breeding trough and is fixedly connected to a bidirectional threaded rod, and the right end of the bidirectional threaded rod is rotatably connected to the right inner wall of the breeding trough.

[0008] Preferably, a moving block is threadedly connected to the bidirectional threaded rod, the rear side of the moving block is slidably connected to the rear inner wall of the breeding trough, and the front side of the moving block is fixedly connected to the hollow plate.

[0009] Preferably, the motor is a servo motor with variable rotation speed.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By using the moving mechanism and the aeration mechanism simultaneously, uniform aeration can be achieved inside the breeding device, improving the uniformity of the overall aeration and preventing uneven aeration from affecting the normal growth of the internal culture. In addition, a shielding mechanism is provided.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-4 The micro-bubble culture device comprises a shell 1, and a culture tank 5 is provided at the upper end of the shell 1;

[0021] The air bubble generating mechanism is also included, and the air bubble generating mechanism includes a hollow plate 8 horizontally arranged in the breeding tank 5, and a plurality of aeration holes 9 are opened on the inner top of the hollow plate 8. A high-pressure air pump 3 is fixedly connected to the left side of the housing 1, and a hose 4 is connected to the air outlet end of the high-pressure air pump 3. The other end of the hose 4 extends into the breeding tank 5 and is connected to the inside of the hollow plate 8.

[0022] Wherein, it also includes a moving mechanism, which is used to move the hollow plate 8 left and right. The moving mechanism includes a motor 2 installed on the left side of the shell 1. The output shaft of the motor 2 extends into the breeding trough 5 and is fixedly connected with a bidirectional threaded rod 6. At this time, a rotating sealing gasket is installed at the place where the motor 2 passes through the shell 1. The right end of the bidirectional threaded rod 6 is rotatably connected to the right inner wall of the breeding trough 5. A moving block 7 is threadedly connected to the bidirectional threaded rod 6. The rear side of the moving block 7 is slidably connected to the rear inner wall of the breeding trough 5. The front side of the moving block 7 is fixedly connected to the hollow plate 8. The motor 2 is a servo motor with variable rotation speed;

[0023] Among them, it also includes a shielding mechanism, which is used to protect multiple aeration holes 9. The shielding mechanism includes a horizontal plate 11 fixedly connected between the front and rear inner walls of the breeding tank 5. A slide groove 12 is opened at the lower end of the horizontal plate 11. A sliding plate 10 that can slide up and down is arranged in the slide groove 12. The upper end of the sliding plate 10 is elastically connected to the inner top of the slide groove 12 through multiple springs 13, and the lower end of the sliding plate 10 contacts the upper end of the hollow plate 8.

[0024] In the utility model, when aeration is not required, Figure 1 State, at this time, the upper end surface of the hollow plate 8 is blocked by the horizontal plate 11 and the sliding plate 10, which can prevent the settled impurities from falling into the hollow plate 8 through the aeration holes 9, and effectively reduce the probability of the aeration holes 9 being blocked;

[0025] When aeration is required, the motor 2 and the high-pressure air pump 3 are started. After the motor 2 is started, the bidirectional threaded rod 6 is driven to rotate, so that the moving block 7 moves left and right, and finally drives the hollow plate 8 to reciprocate left and right. After the high-pressure air pump 3 is started, the gas is pressed into the hollow plate 8, and finally discharged from multiple aeration holes 9 in the form of bubbles. The hollow plate 8 is aerated in a moving state to improve the aeration uniformity.

[0026] It should be noted here that when the hollow plate 8 moves to below the transverse plate 11, the airflow discharged from the aeration holes 9 will move against the sliding plate 10 and overflow from both sides of the sliding plate 10. This can prevent the aeration holes 9 from being blocked when they are displaced to below the transverse plate 11, thereby increasing the load on the high-pressure air pump 3.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
