The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. The following describes an embodiment of the present invention according to its overall structure.

Referring to fig. 1 to 3, the utility model discloses a pipeline conveying device, the pipeline 20 is stirred thoughtlessly of avoiding liquid deposition including a plurality of sections infusion pipeline 10 and a plurality of sections disturbance liquid that are used for carrying liquid, infusion pipeline 10 with the head and the tail both ends of stirring the pipeline 20 thoughtlessly all are provided with flange joint piece, and it is fixed through bolt group between two adjacent flange joint pieces. The interior of the infusion pipeline 10 is a smooth wall surface, the head end and the tail end of the mixing pipeline 20 are both provided with fixed first support frames 21, and the cross section area of each first support frame 21 is smaller than 80% of the cross section of the mixing pipeline 20, so that the first support frames 21 do not obstruct the liquid flow. Further, the surface of the first support frame 21 is provided with an arc transition.

A second support shaft 22, the axis of which is coaxial with the mixing pipe 20, is arranged between the two first support frames 21 of the mixing pipe 20, a stirring blade 23 is arranged on the second support shaft 22, the axis of the stirring blade 23 is penetrated by the second support shaft 22, only the self-rotating freedom degree of the stirring blade 23 is reserved, the stirring blade 23 passively rotates when the fluid impacts the stirring blade, and a limit structure is arranged at a position of the second support shaft 22 corresponding to the end part of the stirring blade 23 to prevent the stirring blade 23 from moving in the axial direction. The stirring blades 23 are passively rotated to both shear and rotate the liquid, thus avoiding the suspended matter from settling in the pipe.

As an improvement of the scheme, the infusion pipelines 10 and the mixing and stirring pipelines 20 are alternately arranged, and the distance between every two adjacent mixing and stirring pipelines 20 is 1m-2m. By adopting the scheme, the stirred liquid can continuously keep a rotating state due to inertia, and the rotating state starts to be greatly weakened after the liquid flows through 1m, so that the manufacturing cost can be reduced by arranging the mixing and stirring pipeline 20 at a reasonable position, and the liquid can be continuously mixed.

As a modification of the above, the passive rotation directions of the stirring vanes 23 of two adjacent mixing pipes 20 are different, so that the liquid is first rotated forward or backward when passing through the first mixing pipe 20, and is stirred in a direction different from the previous rotation when passing through the next mixing pipe 20. By adopting the scheme, the mixing effect is better when the liquid is positively and negatively stirred.

As an improvement of the above scheme, the mixing and stirring pipes 20 have the same structure, and the water inlets of two adjacent mixing and stirring pipes 20 have opposite directions, so that the passive rotating directions of the stirring blades 23 are different. In other embodiments, the stirring blade 23 may be inverted to achieve the same effect. By adopting the scheme of the mixing and stirring pipeline 20, only one structure needs to be manufactured, the manufacturing cost is reduced, and the inlet and outlet directions only need to be simply changed during installation. As shown in fig. 3, the triangular arrow indicates that the liquid entering along the direction can drive the stirring blade 23 to rotate clockwise, and the liquid entering against the direction can drive the stirring blade 23 to rotate counterclockwise, so that the direction is marked for the user to distinguish.

When the mixing and stirring pipeline 20 is manufactured, the second support shaft 22 penetrates through the stirring blade 23, a hoop 24 is arranged on the second support shaft 22, then the first support frames 21 are welded at the head end and the tail end of the second support shaft 22, the components are placed into a conventional pipeline, and finally the components are welded and fixed.

As shown in fig. 2, as an improvement of the above scheme, the first support frame 21 is three round bars uniformly distributed around the circumference of the second support shaft 22, an included angle between two adjacent round bars is 120 °, and the first support frame 21 is welded and fixed to the inner wall of the mixing and stirring pipe 20. In other schemes, the first support frame 21 is an elongated rod, and the second support shaft 22 is connected to a midpoint of the first support frame 21.

As a modification of the above, the limiting structure is a clip 24 fixed to the second support shaft 22, and the two clips 24 limit the stirring blade 23.

As an improvement of the above scheme, the head and the tail ends of the stirring blade 23 at the axis are in a circular truncated cone structure, and the end with the smaller diameter of the circular truncated cone structure faces the end of the mixing pipe 20, so that the obstruction to the flowing liquid is reduced.
