Pipeline anti-blocking device and filling system

The utility model relates to a pipeline anti-blocking device and a filling system.The pipeline anti-blocking device comprises an anti-blocking pipe, at least one flow guide line is arranged on the inner side wall of the anti-blocking pipe in the axis direction of the anti-blocking pipe, and the flow guide line is spirally distributed on the inner side wall of the anti-blocking pipe; the flow guide lines protrude or sink in the radial direction of the anti-blocking pipe relative to the inner side wall of the anti-blocking pipe so that filling fluid can be accelerated. The connecting parts are arranged at the two ends of the anti-blocking pipe and are used for being connected with a filling pipe. The moving track of the filling fluid rotates along the flow guide line, the fluid and particles in the fluid are accelerated, rotated and stirred, and the particles pass through the anti-blocking pipe in an accelerated manner, so that the particles are prevented from depositing to the bottom of the pipe, and the filli
