[0006] Furthermore, four blade supports are evenly spaced apart in a circular plane, and the fan-shaped blades are correspondingly arranged in a quarter-circle structure.

[0007] Furthermore, the blade bracket is formed by connecting a long bracket in the middle through a slot, and the fan-shaped blade is a semicircular structure with the long bracket as the diameter, and the middle part is separated and deflected to both sides.

[0008] Furthermore, the deflection angle of the fan-shaped blades is 45°.

[0009] The pipeline mixer based on the above blades includes a mixing pipeline, in which a plurality of blade groups are axially spaced apart, the blade groups are fixed to the inner wall of the mixing pipeline through the outer ring of the blade bracket, the flow direction of the medium in the pipeline is consistent with the side where the blades of the blade group are located, and the rotation directions of adjacent blade groups are opposite.

[0010] Furthermore, adjacent blade groups are arranged with a circumferential deflection of 45°.

[0011] Beneficial effects: Compared with the prior art, the advantages of the utility model are: adopting a specific structure, changing the medium passage into four, and using a combination of forward and reverse rotating blades, which greatly increases the mixing efficiency, and has a simple structure and is easy to install; it can be processed by laser cutting, with low cost, and is suitable for use in pipes of various sizes.
