Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a mixer integrated with vacuum feeding. Background Art

[0002] In industrial production, mixers are widely used in the pharmaceutical, chemical, food, and plastics industries. Traditional mixer material conveying methods typically rely on manual feeding or simple mechanical conveying, which can easily cause material dust. This not only affects the health of operators and leads to material loss and waste, but also has low feeding efficiency, reducing overall production efficiency. Therefore, traditional mixers cannot meet the material conveying and mixing efficiency requirements of industrial production.

[0003] Vacuum feeding technology uses a vacuum pump or vacuum generator to create a certain vacuum within the conveying pipeline, allowing the material to be drawn into the pipeline due to the air pressure difference and transported to the designated location. To improve the feeding efficiency of the mixer, a mixer incorporating vacuum feeding technology has been developed, providing a more efficient, cleaner, and more precise feeding method for industrial production. However, current mixers with integrated vacuum feeding are typically only compatible with one standard vacuum feeder and cannot be flexibly adapted to different sizes, causing inconvenience during use.
