Description

Technical Field

[0001] The present invention relates to the technical field of raw material pipeline conveying devices, in particular to a raw material pipeline conveying device for foam metal smelting. Background Art

[0002] Foam metal refers to a special metal material containing foam pores. Due to its unique structural characteristics, foam metal has a series of advantages such as low density, good thermal insulation, good sound insulation, and the ability to absorb electromagnetic waves. There are two methods for preparing foam metal: powder metallurgy and electroplating. The former is made by adding a foaming agent to the molten metal, and the latter is replicated into foam metal on a polyurethane foam plastic skeleton through an electroplating process. When transporting metal powder, a pipeline conveying device is often used for feeding.

[0003] Existing pipeline conveying devices for foam metal smelting raw materials transport metal powder along the pipeline under the action of the wind force of the blower. However, in actual use, because the powder needs to be transported from a low point to a high point, powder will accumulate at the bends of the pipeline.
