The aeration pipe cylinder in the aeration equipment is installed at the bottom of the aeration tank for gas circulation, and the aeration head is installed on the aeration pipe cylinder for aeration.
[0003] Generally, the aeration directions of general aeration heads are the same (such as the aeration direction of the aeration disc in the aeration device in Patent CN219689481 U), and the aeration range is limited.
[0004] For the aeration pipe body with a T - shaped pipe body structure, refer to Figure 4 , if the second extrusion feed inlet 11 of the second mold 10 for extrusion molding is arranged at both ends of the aeration pipe body, insufficient extrusion will occur at the intersection line of the pipe bodies of the T - shaped pipe during two - end feeding.

[0006] In order to achieve the above - mentioned purpose, the utility model adopts the following technical scheme:
[0007] A one - word - shaped swirling aeration cylinder includes an aeration pipeline. One side of the middle part of the aeration pipeline is provided with an air inlet pipe communicated with the aeration pipeline. The axis of the air inlet pipe is perpendicular to the axis of the aeration pipeline. On the other side of the middle part of the aeration pipeline, a columnar convex block is provided, and the columnar convex block is coaxially arranged with the air inlet pipe;
[0008] Between the connection pipe holes at both ends of the aeration pipeline, a first aeration branch pipe and a second aeration branch pipe are arranged. The first aeration branch pipe is located at the first end of the aeration pipeline, and the second aeration branch pipe is located at the second end of the aeration pipeline. The first aeration branch pipe and the second aeration branch pipe are bent pipes, and the exhaust directions of the first aeration branch pipe and the second aeration branch pipe are opposite.
[0009] Preferably, the aeration pipeline, the air inlet pipe, the first aeration branch pipe, the second aeration branch pipe and the columnar convex block are integrally formed.
[0010] The utility model also proposes a mold for producing the above - mentioned one - word - shaped swirling aeration cylinder. The extrusion feed inlet of the mold is located in the middle of the aeration pipeline.
[0011] Preferably, the extrusion feeding port of the mold is located above the columnar convex block.
