[0034] Specifically, a stirring rack 2 is provided in the filling bin 1, which continuously stirs during the process of adding the drag reducer and filling to reduce stratification, and a filter barrel 3 is provided. During the stirring process, filtering is performed through the filter barrel 3 to reduce the possibility of incompletely stirred lumps entering the pipeline and causing blockage.

[0035] In this way, by providing the stirring rack 2 for stirring, the stratification of the drag reducer solution is reduced, and the possibility of incompletely stirred lumps entering the pipeline and causing blockage is reduced through the filter barrel 3.

[0036] In some feasible embodiments, the filling tank 1 is a cylindrical tank, and the filter barrel 3 is a cylindrical tank with porous plate sidewalls and a bottom. The feed port 11 and feed pipe 12 are positioned above the filter barrel 3, allowing the drag reducer and solvent to enter the filter barrel 3 for mixing before they are fused. The feed pipe 12 is connected to a petroleum pipeline, using petroleum as the solvent to minimize the impact of other solvents on petroleum quality. A filling pipe 5 is positioned at the bottom of the filling tank 1, with the inlet located outside the filter barrel 3. A booster pump 51 is used to pressurize the liquid in the filling pipe 5 for easy entry into the petroleum pipeline.

[0037] As a specific embodiment of the drag reducer filling structure for pipeline transportation provided in the application, a partition plate 13 is provided in the middle of the filling chamber 1. The partition plate 13 divides the stirring frame 2 into an upper chamber 201 and a lower chamber 202. The upper chamber 201 and the lower chamber 202 are connected by a rotating shaft passing through the partition plate 13. The filter barrel 3 is located in the upper chamber 201. The partition plate 13 is provided with a flow hole, and the flow hole is equipped with a control valve 41. The partition plate 13 is fixedly installed with an exhaust pipe 131, which extends upward through the filling chamber 1. To reduce backflow during the filling process, the feed pipe 12 and the filling pipe 5 are both equipped with a one-way valve at one end.

[0038] Overall, by setting The partition plate 13 divides the filling tank 1 into two spaces. By setting a control valve 41, the two spaces can be independent of each other.
