Description

Technical Field

[0001] The utility model relates to the technical field of additive manufacturing, and in particular to a novel cyclone separator for additive manufacturing. Background Art

[0002] In the field of additive manufacturing, cyclone separators are used to improve the recycling rate of metal powder. Figure 1 A cyclone separator typically consists of a spiral section, an outer cylinder, an inner cylinder, and a cone. After use, metal powder remains on the inner surface of the cyclone. This metal powder is typically distributed on the surfaces of the spiral section and inner cylinder and cannot be removed by strong airflow. This powder requires the operator to wipe it with a cotton cloth dipped in anhydrous ethanol. However, the spiral section and outer cylinder of a suitable cyclone separator are small in diameter, making it difficult for a human hand to fully reach and wipe it. This is usually done using a steel pipe with an anhydrous ethanol cloth attached to it. The absence of metal powder on the cloth indicates that the cyclone's inner surface is clean. To prevent contamination between different types of metal powder when changing powders within the same device, operators perform a cleaning operation on the cyclone separator. However, because traditional cyclones are welded together, the spiral joints are difficult to clean thoroughly, making this operation time-consuming and labor-intensive. Furthermore, conventional cyclones lack grounding, posing a risk of dust explosions. Furthermore, existing cyclones suffer from overhead flow, which reduces separation efficiency.
