Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment: An aeration assembly for animal protein fermentation, such as Figure 1-Figure 3 The invention comprises a chassis 1, an upper cover 2 and a rotating shaft 3. The upper cover 2 is a shell with an open top. The chassis 1 can be detachably mounted on the upper cover 2 for easy maintenance. Aeration components are evenly arranged on the upper cover 2. An air inlet pipe 8 communicating with the chassis 1 is fixedly mounted in the middle of the bottom end surface of the chassis 1. Oxygen enters the chassis 1 through the rotating shaft 3 and is ejected from the aeration component on the upper cover 2.

[0024] In particular, the aeration assembly includes a rotating shaft 3, which is fixedly installed in the middle of the chassis 1, and a first plate 4 and a second plate 5 are movably installed on the top of the rotating shaft 3, and the first plate 4 and the second plate 5 are fixedly connected. A plurality of aeration nozzles 7 are fixedly installed on the first plate 4 and the second plate 5, and a bellows 6 is fixedly installed between each group of aeration nozzles 7 and the chassis 1, and oxygen passes through the bellows 6 and is sprayed from the aeration nozzle 7, wherein the top of the aeration nozzle 7 is inclined, and the aeration nozzles 7 at both ends of the first plate 4 and the aeration nozzles 7 at both ends of the second plate 5 are bent in opposite directions, and the aeration nozzles 7 at both ends of the first plate 4 are bent in opposite directions. When the aeration nozzle 7 on the first plate 4 is aerated, the first plate 4 is driven to rotate around the central shaft 3. Similarly, when the aeration nozzle 7 on the second plate 5 is aerated, the second plate 5 also rotates around the central shaft 3. Further, the aeration nozzle 7 on the adjacent end of the first plate 4 and the second plate 5 is inclined in opposite directions. When the aeration nozzle 7 on the first plate 4 or the second plate 5 is supplied with air, the first plate 4 and the second plate 5 are rotated reciprocatingly. During aeration, it can be evenly distributed inside the fermenter, and the swinging bellows 6 can stir the protein liquid in the fermenter to improve the uniformity of the protein liquid fermentation.

[0025] Furthermore, an active rotating shaft 10 is movably installed in the chassis 1 and can rotate in the chassis 1. A baffle 12 is fixedly installed on the top of the active rotating shaft 10. The baffle 12 is in contact with the upper cover 2 and can regularly block the aeration nozzles 7 related to the first plate 4 and the second plate 5 from inputting oxygen during the rotation process.

[0026] In a preferred embodiment, the first plate 4 and the second plate 5 are staggered at an angle of ninety degrees, and the baffle 12 is composed of two groups of ninety-degree fan-shaped plates. During the continuous rotation of the baffle 12, the aeration input on the first plate 4 and the second plate 5 is regularly blocked.

[0027] Furthermore, the active rotating shaft 10 extends into the air intake pipe 8, and at least two groups of fixed plates 9 are fixedly installed on the inner wall surface of the air intake pipe 8 from top to bottom. The part of the active rotating shaft 10 extending into the fixed plate 9 penetrates the fixed plate 9 and is movably connected to the fixed plate 9 through a bearing. The part of the active rotating shaft 10 extending into the air intake pipe 8 has multiple groups of fan blades 11 fixedly installed at uniform intervals. When the high-pressure oxygen gas flow passes through the fan blades 11, the fan blades 11 are driven to drive the active rotating shaft 10 to rotate, and then drive the baffle 12 to rotate, thereby improving the degree of automation, without relying on drivers such as motors, and reducing energy consumption.

The corrugated pipe 6 can be easily replaced by setting the pipe base 13 and the pipe top seat 14.

[0029] The working principle of the utility model is as follows: high-pressure oxygen enters the chassis 1 through the air inlet pipe 8, and then is sprayed out from the aeration nozzle 7 through the bellows 6 on the upper cover 2. When the aeration nozzle 7 on the first plate 4 aerates, the first plate 4 is driven to rotate around the central shaft 3. Similarly, when the aeration nozzle 7 on the second plate 5 aerates, the second plate 5 also rotates around the central shaft 3. When air is supplied to the aeration nozzle 7 on the first plate 4 or the second plate 5, the first plate 4 and the second plate 5 are rotated reciprocatingly. During aeration, the air can be evenly distributed inside the fermentation tank, and the swinging bellows 6 can stir the protein liquid in the fermentation tank to improve the uniformity of the protein liquid fermentation.

[0030] In addition, by using the fan blades 11 on the active rotating shaft 10, when high-pressure oxygen passes through, the fan blades 11 can drive the active rotating shaft 10 to rotate, thereby driving the baffle 12 to rotate under the upper cover 2, and a filtered circulation is provided to supply air to the bellows 6 connected to the first plate 4 and the second plate 5.
