Technical Field

[0001] The utility model belongs to the technical field of mixing devices, in particular to a powder mixing device for producing double-wall corrugated pipes. Background Art

[0002] Double-wall corrugated pipe is a lightweight, high-strength, corrosion-resistant plastic pipe with a smooth inner wall and corrugated outer wall. It is commonly used in municipal engineering, drainage systems, farmland irrigation and other fields. It is widely used in underground pipeline systems due to its excellent ring stiffness and good chemical stability. The production process of double-wall corrugated pipe mainly includes raw material preparation, mixing and stirring, melt extrusion, molding and cooling, sizing and cutting, quality inspection, packaging, storage and delivery to ensure that the quality of the pipe meets the standards and meets customer needs.

[0003] At present, most of the mixing barrels of the mixers used in the production of double-wall corrugated pipes are arranged vertically, which may result in residual powder when discharging, affecting the quality of the next batch of mixed powder products, and the mixing barrel is inconvenient to clean.
